    EIGHTH DISTRICT OF TEXAS
    EL PASO, TEXAS
    §                No. 08-21-00058-CV
    IN THE INTEREST OF:
    §                   Appeal from the
    D.A.A.-B.,
    §                 388th District Court
    A CHILD.
    §              of El Paso County, Texas
    §               (TC# 2016DCM0868 )
    OPINION
    The parties here were in a legally recognized same-sex marriage during which one of the
    spouses conceived and bore a child through artificial insemination. This appeal asks us to
    determine whether, following divorce, the non-biological former spouse has standing to bring a
    Suit Affecting the Parent-Child Relationship (SAPCR) to determine her rights to possession of the
    child, as well as child support issues. The trial court ruled that the non-biological spouse lacked
    standing to bring the suit, in part, because the court believed she did not meet the definition of a
    “parent” under the gender-specific definitions set forth in the Texas Family Code. Interpreting
    the Family Code in a gender-neutral fashion, as we are constitutionally required to do, we conclude
    that the non-biological spouse has standing to file a SAPCR petition based on her allegation that
    she is the child’s mother. Although we do not reach the merits of her allegation, we simply hold
    that she is entitled to her day in court. We therefore reverse the order of dismissal of the SAPCR,
    and remand the case for further proceedings.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    A. The Parties’ Marriage and Divorce
    The two former spouses, Cristina and Andrea,1 were legally married in New Mexico in
    2013.2 During the marriage, they agreed that Andrea would become pregnant through artificial
    insemination, using sperm donated by a male friend, who we refer to as “Luis.” The parties did
    not utilize a doctor or other medical professional to accomplish the insemination, but did so at
    home using an insemination kit that Cristina and Andrea had bought for this purpose. Cristina
    participated in the insemination procedure, with the understanding that she and Andrea would both
    be considered the child’s parents. The insemination succeeded, and Cristina attended all of
    Andrea’s OB-GYN appointments, and the two attended multiple baby showers before the child’s
    birth.
    Andrea gave birth to the child in an El Paso hospital on August 27, 2014, with Cristina
    present. Andrea informed the hospital’s registrar that she and Cristina were both the child’s
    parents, but since same-sex marriages were not yet legal in Texas, they could not list Cristina as
    the other parent on the birth certificate; only Andrea’s name appears on it. However, at Andrea’s
    request, the child’s surname, as it appears on the birth certificate, is a combination of the two
    spouse’s last names.
    Over the next two years, Andrea and Cristina raised the child together in the same home,
    1
    To protect the identity of the child, we refer to the parties solely by their first names.
    2
    In the proceedings below, Cristina presented uncontested testimony and evidence about the circumstances of the
    parties’ marriage and divorce, the events occurring both before and after the birth of the child, and the oral agreements
    that the parties had over the child and her parentage. We take our recitation of the facts from that testimony.
    2
    shared parenting duties, represented to others that the child belonged to both of them, and
    encouraged the creation of a bond between the child and their extended families. However, the
    spouses separated in November 2015, with Cristina remaining in the family home, while Andrea
    first moved out with a family member. Shortly before the separation, Cristina began suffering
    from depression, and began counseling. And during this same time, Cristina was diagnosed with
    cancer that required her to undergo chemotherapy treatments.
    Despite knowing of Cristina’s medical and mental health issues, Andrea—who appeared
    to have taken primary custody of the child—gave Cristina assurances, as reflected in a series of
    text messages between the two, that Cristina would always be the child’s mother and would have
    the right to spend time with her. The two entered into an informal oral agreement resembling a
    standard possession schedule in which Cristina had possession of the child every other weekend,
    as well as every Wednesday starting at 4:00 pm until Thursday at 7:00 pm.3 In addition, (1)
    Cristina routinely picked up the child Sunday night on Andrea’s weekends keeping her until
    Monday morning, (2) the two split holidays and school vacation days by agreement, and (3)
    Cristina took possession of the child at other times when Andrea’s work schedule required her to
    travel. During the child’s overnight visits, Cristina would perform typical parenting duties,
    including bathing the child, dressing her, and brushing her teeth. Cristina also began paying Andrea
    a minimum of $100 in child support each month, representing her half of the child’s daycare
    expenses, and further kept the child on her health insurance through her employment.
    In April 2016, Andrea filed a divorce petition in an El Paso district court, and the two,
    3
    A standard possession schedule provides that “the possessory conservator shall have the right to possession of the
    child as follows: (1) on weekends throughout the year beginning at 6 p.m. on the first, third, and fifth Friday of each
    month and ending at 6 p.m. on the following Sunday; and (2) on Thursdays of each week during the regular school
    term beginning at 6 p.m. and ending at 8 p.m., unless the court finds that visitation under this subdivision is not in the
    best interest of the child.” TEX.FAM.CODE ANN. § 153.312.
    3
    proceeding without counsel, obtained an agreed-upon divorce decree. In the petition, however, due
    to what Cristina described as “confusion,” Andrea stated that there were no children of the
    marriage, and the decree contained that statement as well, and the decree thus did not address
    custody, visitation, or support issues for the child.4 Despite the decree’s failure to address custody
    or support issues, the spouses orally agreed that they would maintain the same possession schedule
    they had been following since their separation, and Cristina continued to make support payments
    to Andrea and kept the child on her insurance. According to Cristina, there were periods when
    she had possession of the child for more than 50% of the time after the divorce. Cristina, however,
    admitted that she never adopted the child or sought any court decree determining her rights until
    she filed the SAPCR petition, explaining that she did not believe it was necessary to do so given
    the assurances Andrea had given her that she would not deny Cristina her rights as a parent.
    According to Cristina, their informal arrangement continued without incident until
    September 2017 when the two began to have “arguments.”                             Cristina testified that Andrea
    thereafter unilaterally decided to stop allowing Cristina to have overnight visitation with the child,
    claiming that she was concerned about Cristina’s mental and physical health, and that she believed
    Cristina’s “judgment was off.” Cristina recalled that her last overnight visit with the child was on
    or about September 30, 2017. Despite being denied visitation, Cristina continued to send Andrea
    support payments and kept the child on her insurance policy.
    B. Cristina Files Her Original SAPCR Petition
    In November 2017, Cristina filed her original SAPCR petition, seeking the entry of a
    conservatorship order to determine custody and support issues, alleging that she had standing to
    4.
    The record indicates that Cristina filed a bill of review to clarify the divorce decree, which the trial court ruled on
    at some point during the pendency of the SAPCR proceedings. However, the record before us does not contain any
    information regarding that ruling.
    4
    bring the suit as “the mother of the child.” In her petition, Cristina sought temporary orders
    appointing her and Andrea as joint managing conservators, and giving Cristina the exclusive right
    to designate the child’s primary residence. She also sought an order requiring Andrea to pay child
    support. In response, Andrea filed a general denial of Cristina’s allegations, and expressly denied
    that Cristina was the child’s mother.
    At the first hearing on Cristina’s request for temporary orders, the trial court refused to rule
    on the request until Luis, the sperm donor, could be served, so that the court could determine his
    rights to the child, if any. Cristina then filed an amended SAPCR petition, which she served on
    Luis, again alleging that she had standing as the mother of the child. Luis filed a general denial,
    but did not expressly deny Cristina’s status as the mother of the child, and did not seek to have his
    rights adjudicated over the child.
    C. The Trial Court Denies Cristina’s Request for Temporary Orders
    In September 2018, the trial court held a second hearing on Cristina’s request for temporary
    orders, at which all parties were represented by counsel. Cristina was the only witness at the
    hearing. She testified to the facts set forth above about the parties’ marriage, the oral agreements
    she had with Andrea on the child’s parentage, and Cristina’s right to possession of the child. In
    addition, Cristina testified that Luis never provided any financial assistance for the child’s
    support—nor had she and Andrea expected him to do so. Neither Andrea nor Luis contradicted
    Cristina’s testimony, and Luis never asserted that he was claiming any rights to the child.
    At the close of the hearing, Andrea made an oral motion for a directed verdict, arguing that
    Cristina lacked standing under the Texas Family Code to bring her SAPCR petition because she
    did “not meet the definition of mother” as set forth in the Code. Andrea emphasized that Cristina
    was admittedly not the child’s biological mother and never adopted the child. As explained
    5
    below, Cristina responded that she had standing under recent decisions from the United States
    Supreme Court recognizing the constitutional right of a spouse in a same-sex marriage to be treated
    just as a spouse in an opposite-sex marriage when determining parentage issues of a child born
    during the marriage. At the close of the hearing, the trial court stated that it was granting Andrea’s
    motion for a directed verdict. In particular, the court expressed its opinion that Cristina could not
    be considered the child’s parent, as she was admittedly not the child’s biological mother, and that
    there was “not a presumption of paternity anymore, because [Cristina] identified [Luis as] the
    father.”
    Following the hearing, the trial court denied Cristina’s request for temporary orders. In
    its order, the court expressly found that Cristina “lacked standing to maintain a Suit Affecting the
    Parent Child Relationship under Texas Family Code § 102.003(1) as she does not meet the Texas
    Family Code definition of parent as set forth in § 101.024, nor has the mother-child relationship
    been established under § 160.201 of the Texas Family Code.” The trial court, however, did not
    enter a final order denying Cristina’s SAPCR petition at that time.
    D. Cristina Files Her Second Amended SAPCR Petition
    Soon after, Cristina filed her second amended SAPCR petition, again seeking a
    conservatorship order, but this time alleging that she had standing to sue as “she is a person, other
    than a foster parent, who has had actual care, control, and possession of the child for at least six
    months ending not more than 90 days preceding the date of the filing of the petition pursuant to
    Texas Family Code section 102.003(a)(9).” 5                   And she once again sought temporary orders
    5
    Section 102.003(a)(9) provides that “An original suit may be filed at any time by . . . a person, other than a foster
    parent, who has had actual care, control, and possession of the child for at least six months ending not more than 90
    days preceding the date of the filing of the petition.” TEX.FAM.CODE ANN. § 102.003(a)(9).
    6
    appointing the parties as temporary joint conservators. However, she did not renew her allegation
    that she was the child’s “parent” in her amended petition.
    E. The Trial Court Grants Andrea’s Motion to Dismiss Cristina’s Petition
    Andrea thereafter moved to dismiss Cristina’s second amended petition, arguing that
    Cristina lacked standing to bring her petition, as she did not have actual care, control, or possession
    of the child for the required 90 days before filing her amended petition. In particular, she pointed
    out that Cristina admitted that she did not have possession of the child after September 30, 2017,
    and she argued that Cristina had only 90 days thereafter in which to file a petition asserting
    standing on that basis. And she also argued that, although Cristina filed her original petition
    within that 90-day period, she failed to allege in her original petition that she had standing on that
    basis, and it was too late to allege standing on that basis over a year later in her amended petition.
    In response, Cristina argued that her amended petition should relate back to the date she filed her
    original petition, which she contended should be considered the operative date for determining
    whether she had standing under this Code provision.6
    The trial court heard Andrea’s motion in October 2019, and at the end of the hearing, stated
    that it would take the matter under submission pending its review of the parties’ post-trial briefs.
    The court advised the parties, however, that she would not rule on Cristina’s renewed motion for
    temporary orders, believing that it would not be in the child’s best interest to “rekindle” her
    relationship with Cristina, as the relationship might not be permanent. Over a year later, on
    December 30, 2020, on the trial court judge’s last day in office, she signed an order granting
    Andrea’s motion to dismiss Cristina’s SAPCR petition, without providing any findings of fact or
    6
    At the hearing on Andrea’s motion to dismiss, as well as in post-hearing briefs, the parties also argued over whether
    Cristina had established that she had actual care, control, and possession of the child during the six months preceding
    the filing of her original petition as required by the Family Code.
    7
    conclusions of law. Cristina thereafter filed a request with the newly elected trial court judge
    seeking such findings under Rule 296 of the Texas Rules of Civil Procedure, and further filed a
    motion for new trial. Ultimately, however, the newly elected judge declined to enter any findings
    of fact or conclusions of law and denied Cristina’s motion for new trial.7 This appeal followed.
    II. ISSUES ON APPEAL
    In her first issue, Cristina contends that the trial court erred in finding that she lacked
    standing to bring her original SAPCR petition as the child’s parent under section 102.003(a)(1) of
    the Texas Family Code. The crux of the argument is that the trial court failed to construe the
    Code in a constitutionally-sound “gender-neutral” manner that affords spouses in same-sex
    marriages the same rights that spouses in opposite-sex marriages have in determining parentage.
    Andrea counters that Cristina cannot be considered the child’s “mother” under the gender-specific
    provisions set forth in the Family Code defining that term, and that in any event, Cristina waived
    her right to claim standing as a “parent” on appeal because: (1) Cristina only pled that she was the
    child’s “mother,” rather than her “parent,” in her original and first amended petitions; (2) Cristina
    eliminated her claim that she was the child’s mother as the basis for standing in her second
    amended petition, which is her “live pleading”; and (3) Cristina did not raise her constitutional
    challenges over her right to assert standing as a parent in a written pleading. Although we
    typically address waiver or preservation issues first, we find it appropriate here to first discuss the
    merits of Cristina’s and to address the waiver issues in the context of that discussion.
    In her second issue, Cristina contends that she has standing under section 102.003(a)(9) of
    the Code—as alleged in her second amended petition—arguing that she had possession of the child
    7
    Initially, the newly elected trial court judge issued an order granting in part Cristina’s motion for new trial, but later
    vacated that order and reinstated the original order dismissing Cristina’s petition.
    8
    for over six months, ending within 90 days of the date she filed her original petition, and that this
    allegation should relate back to date on which she filed her second amended petition, making it
    timely filed We need not address this issue, however, as we resolve Cristina’s first issue in her
    favor, finding that she has standing as the child’s parent under section 102.003(a)(1) of the Code.
    III. STANDARD OF REVIEW
    In general, standing involves a threshold determination of whether a plaintiff has a
    sufficient “justiciable interest” in the suit’s outcome to be entitled to a judicial determination. In
    Interest of H.S., 
    550 S.W.3d 151
    , 155 (Tex. 2018). “Without standing, a court lacks subject
    matter jurisdiction” over the case, and the merits of the plaintiff’s claims thus cannot be litigated
    or decided. 
    Id.,
     quoting Austin Nursing Ctr. v. Lovato, 
    171 S.W.3d 845
    , 849 (Tex. 2005); see also
    In re T.M.P., 
    417 S.W.3d 557
    , 566 (Tex.App.--El Paso 2013, no pet.) (recognizing that standing
    is a threshold issue in a case involving child custody and visitation issues, and is a component of
    subject matter jurisdiction); In re H.R.L., 
    458 S.W.3d 23
    , 29 (Tex.App.--El Paso 2014, no pet.)
    (recognizing that a party’s lack of standing in a child custody case deprives the trial court of subject
    matter jurisdiction). The question of whether an individual has standing must be determined
    before a court may reach the merits of the individual’s claims. In Interest of H.S., 550 S.W.3d at
    155 (recognizing that a standing issue is not about whether an individual will prevail in their suit,
    but about whether they may sue in the first place).
    Whether a party has standing, like other issues implicating a court’s subject matter
    jurisdiction, is a question of law that an appellate court reviews de novo. Id.; see also In re J.M.G.,
    
    553 S.W.3d 137
    , 141 (Tex.App.--El Paso 2018, no pet.). In evaluating standing, we construe the
    pleadings in the plaintiff's favor, but we also consider relevant evidence offered by the parties. In
    Interest of H.S., 550 S.W.3d at 155, citing Bland Indep. Sch. Dist. v. Blue, 
    34 S.W.3d 547
    , 555
    9
    (Tex. 2000). And when, as here, the trial court has entered no findings of fact or conclusions of
    law, we will imply that the trial court made all findings necessary to support its judgment, provided
    that: (1) the necessary findings are raised by the pleadings and supported by the evidence; and (2)
    the decision can be sustained by any reasonable theory consistent with the evidence and applicable
    law. See Worford v. Stamper, 
    801 S.W.2d 108
    , 109 (Tex. 1990) (per curiam,); see also Viera v.
    Viera, 
    331 S.W.3d 195
    , 204 (Tex.App.--El Paso 2011, no pet.) (applying rule in reviewing a trial
    court’s judgment in a child custody case).
    IV. CRISTINA’S STANDING AS A PARENT
    Title 5 of the Texas Family Code, entitled “The Parent-Child Relationship and the Suit
    Affecting the Parent-Child Relationship,” governs standing questions in all SAPCR proceedings.
    See In Interest of H.S., 550 S.W.3d at 155 (recognizing that standing to bring a SAPCR petition is
    governed by section 102.003 of the Family Code). Section 102.003 of the Code, found in Subtitle
    A, provides that an original SAPCR proceeding “may be filed at any time by . . . a parent of the
    child.” TEX.FAM.CODE ANN. § 102.003(a)(1). And in turn, section 101.024 of the Code, also
    found in Subtitle A, provides that a “parent” means “the mother, a man presumed to be the father,
    a man legally determined to be the father, a man who has been adjudicated to be the father by a
    court of competent jurisdiction, a man who has acknowledged his paternity under applicable law,
    or an adoptive mother or father.” Id. §101.024. However, Subtitle A does not provide any
    definitions for determining who may be considered either a “mother” or a “presumed father” for
    purposes of bringing a SAPCR proceeding. Instead, Subtitle A directs our attention to Subtitle B
    of the Code, and more particularly to Chapter 160, known as the Uniform Parentage Act (UPA),
    which the Texas Legislature adopted in 2001, for guidance in determining who fits within these
    definitions. See TEX.FAM.CODE ANN. § 101.025 (the “[p]arent-child relationship” means the
    10
    legal relationship between a child and the child’s parents as provided by Chapter 160 [and]
    includes the mother and child relationship and the father and child relationship”).8
    In turn, section 160.204(a)(1) of the UPA provides that a “man is presumed to be the father
    of the child if he is married to the mother of the child and the child is born during the marriage.”
    TEX.FAM.CODE ANN. § 160.204 (a)(1).                 In addition, the Act provides that a “father-child”
    relationship between a “man and a child,” may be established by, among other things, (1) an
    “unrebutted presumption” that the man is the father of a child born during the marriage in
    accordance with section 160.204 of the Family Code, or (2) that he consented to “assisted
    reproduction” by his wife under Subchapter H of the Code, which resulted in the birth of the child.
    Id. § 160.201(b)(1)(5). But section 160.201 provides a very different method of establishing the
    “mother-child relationship, providing that the relationship is established between a “woman and a
    child” by: “(1) the woman giving birth to the child; (2) an adjudication of the woman’s maternity;
    or (3) the adoption of the child by the woman.” Id. § 160.201(a)(1)-(3).
    Given the gender-specific terminology of these provisions, if viewed in isolation, one
    might conclude that section 160.201 only applies to establishing a man’s paternity for a child born
    during an opposite-sex marriage, and does not apply to establish the maternity of a female spouse
    in a same-sex marriage under these same circumstances. However, because we cannot view these
    provisions in isolation, we find that this apparent interpretation by the trial court was in error.
    8
    To the extent that the concurring opinion believes that the definitions set forth in the UPA are not applicable to
    SAPCR proceedings, we disagree. As set forth above, the Code expressly provides that the definitions set forth in
    the UPA are to be applied to original SAPCR proceedings. Section 106.103(a) provides that the UPA governs every
    determination of parentage in this state. TEX.FAM.CODE ANN. § 160.103(a). Accordingly, in determining whether
    Cristina has standing to bring an original SAPCR petition in her status as a parent under section 102.003(1), we must
    necessarily look to the provisions of the UPA in making that determination.
    11
    A. Viewing the Texas Family Code Through the Lens of Obergefell and Pavan
    Our interpretation of the Code is necessarily guided by the United States Supreme Court’s
    rulings in Obergefell and its progeny, addressing the rights of spouses in same-sex marriages. In
    2015, the Court in Obergefell held that “the right to marry is a fundamental right inherent in the
    liberty of the person, and [that] under the Due Process and Equal Protection Clauses of the
    Fourteenth Amendment couples of the same-sex may not be deprived of that right and that liberty.”
    Obergefell v. Hodges, 
    576 U.S. 644
    , 675 (2015). Thus, the Court held that state laws must treat
    same-sex couples in a civil marriage “on the same terms and conditions as opposite-sex couples.”
    Id. at 675-76 (holding that Michigan state laws were invalid when they excluded same-sex couples
    from civil marriage). As well, the Court in Obergefell further held that there was “no lawful basis
    for a State to refuse to recognize a lawful same-sex marriage performed in another State on the
    ground of its same-sex character.” Id. at 681.
    Soon after, the Court, relying on its ruling in Obergefell, further recognized that spouses in
    same-sex marriages are also entitled to equal rights when it comes to children born of the marriage.
    Pavan v. Smith, 
    137 S. Ct. 2075
    , 2078–79 (2017) (per curiam). In that case, a same-sex couple
    was denied the right to have both of their names placed on the birth certificate of a child they had
    conceived through artificial insemination, based on an Arkansas statute that provided for the
    inclusion of the birth mother’s name on the birth certificate, and if married, the name of her
    “husband.” 
    Id. at 2077
    . The Arkansas Supreme Court held that the statute did not sidestep
    Obergefell, reasoning that the “statute centers on the relationship of the biological mother and the
    biological father to the child, not on the marital relationship of husband and wife.” 
    Id. at 2077
    .
    The United States Supreme Court disagreed, however, finding that the decision “denied married
    same-sex couples access to the “constellation of benefits that the Stat[e] ha[s] linked to marriage.”
    12
    
    Id. at 2078
    , citing Obergefell, 576 U.S. at 646-47. The Court reasoned that because the State gave
    a married woman in Arkansas who conceives a child by means of artificial insemination, the right,
    if not the duty, to put her male spouse’s name on the child’s birth certificate, it could not deny the
    same right of a married woman in a same-sex marriage to put her female spouse’s name on the
    certificate. Id. The Court further noted that being recognized as the parent of the child on a birth
    certificate gives a parent “important” rights, such as making medical decisions for the child or
    enrolling the child in school. Id. And in turn, the Court held that the Arkansas statute, as
    interpreted by the Arkansas Supreme Court, denied “same-sex parents” the benefits that the state
    accorded to parents in an opposite-sex marriage, resulting in the same type of “disparate treatment”
    that Obergefell proscribes. Id.
    We must therefore interpret the standing provisions in the Texas Family Code in
    accordance with the constitutional requirements of Obergefell and Pavan. See Treto v. Treto, 
    622 S.W.3d 397
    , 401–02 (Tex.App.--Corpus Christi–Edinburg 2020, no pet.) (recognizing the need to
    construe statutes, including the Texas Family Code, in a manner that is consist with the Texas and
    federal constitutions); see also City of Pasadena v. Smith, 
    292 S.W.3d 14
    , 19 (Tex. 2009), quoting
    City of Houston v. Clark, 
    197 S.W.3d 314
    , 324 (Tex. 2006) (recognizing that “[w]hen faced with
    multiple constructions of a statute, we must interpret the statutory language in a manner that
    renders it constitutional if it is possible to do so.”); see also TEX. GOV’T CODE ANN. § 311.021(1)
    (“[i]n enacting a statute, it is presumed that . . . compliance with the constitutions of this state and
    the United States is intended”). In other words, if possible, we must construe these provisions in
    a manner that affords spouses in a same-sex marriage the same benefits granted to spouses in an
    opposite-sex marriage—which includes treating them equally when determining whether a spouse
    (or former spouse) in a same-sex marriage has standing to bring a SAPCR petition to assert her
    13
    rights to a child born during the marriage. See Treto, 622 S.W.3d at 401–02 (recognizing that
    under Pavan, we are to give effect to the ancillary benefits of a same–sex marriage, including the
    determination of maternity for the non–gestational spouse of a child born to the marriage).
    And we can do so here based on the provisions of the Code itself. The UPA includes a
    section stating that the “provisions of this chapter relating to the determination of paternity apply
    to a determination of maternity.” TEX.FAM.CODE ANN. § 160.106. The unambiguous and plain
    language of this statute make it clear that the legislature intended to allow female spouses to
    establish their parentage just as male spouses are allowed to do. See Treto, 622 S.W.3d at 401–
    02 (concluding that section 160.106 of the Code must be read together with other provisions in the
    Family Code to give spouses in same-sex marriages the right to establish their parentage just like
    spouses in opposite-sex marriages have); see also Maxim Crane Works, L.P. v. Zurich Am. Ins.
    Co., 
    642 S.W.3d 551
    , 557 (Tex. 2022) (recognizing that in interpreting statutes, a court looks to
    the “plain meaning of the words chosen” by the legislature, and if the “statute is clear and
    unambiguous,” a court must apply its words according to their common meaning). When read
    alongside the U.S. Supreme Court’s holding that states must extend equal benefits to spouses in
    same-sex marriages, we reach the inexorable conclusion that the Family Code gives spouses in
    same-sex marriages the same opportunity to assert their parentage to a child born during the
    marriage, as it gives to spouses in opposite-sex marriages. This interpretation not only gives
    effect to all relevant portions of the Code, as written by the legislature, but also avoids an
    interpretation of the Code that would render it unconstitutional under the U.S. Supreme Court’s
    holdings. Treto, 622 S.W.3d at 402.
    B. The Code’s Presumed Parentage Provisions
    In the only Texas case that we have found applying the holding in Pavan in determining
    14
    the parental rights of spouses in same-sex marriages, our sister court in Treto used a similar
    analysis, and concluded that a female spouse in a same-sex marriage was the “presumed” parent
    of a child born during that marriage under a constitutionally-sound interpretation of the Code.9
    Id. at 402-403. As here, the two female spouses in Treto agreed that one of them (the gestational
    spouse) would become pregnant through means of artificial insemination conducted in a non-
    medical setting, and she successfully gave birth to a child during their marriage. Id. at 398.
    Unlike the current case, however, when the two spouses divorced, the non-gestational spouse
    sought to avoid a judgment declaring her the child’s parent and ordering her to pay child support.
    Id. at 399. In particular, she argued that she did not meet the definition of a parent under the
    Family Code, as she was not the child’s biological mother. Id. Our sister court disagreed, noting
    that under the Family Code, if “gender was not an issue,” the non-gestational spouse would be
    treated as the presumed “father” because she was married to the gestational spouse then she
    became pregnant and the child was born of the marriage. Id. at 400, citing TEX.FAM.CODE ANN. §
    160.204(a)(1) (“A man is presumed to be the father of a child if . . . he is married to the mother of
    the child and the child is born during the marriage.”). And in turn, the court held that under the
    Supreme Court’s ruling in Pavan, it was necessary to interpret this statute to apply equally to
    9
    Andrea relies on the Beaumont court’s holding in In re A.E., No. 09-16-00019-CV, 
    2017 WL 1535101
    , at *8
    (Tex.App.--Beaumont Apr. 27, 2017, pet. denied) (mem. op.), in which it held that a female spouse in a same-sex
    marriage lacked standing to bring a SAPCR petition to determine her rights to a child born during the marriage by
    means of artificial insemination, as she was not the child’s biological mother, and did not otherwise have any right to
    claim that she was a parent under the Family Code. In that case, the Beaumont court rejected the non-gestational
    spouse’s argument that the Family Code provisions should be interpreted in a gender-neutral manner under the
    Supreme Court’s holding in Obergefell. Id. at *3. The Beaumont court expressed its view that Obergefell was
    limited to prohibiting “the State from enforcing laws prohibiting same-sex couples from marrying or prohibiting the
    recognition of marriages between same-sex couples lawfully solemnized elsewhere.” Id., citing Obergefell, 135
    S. Ct. at 2605. And it concluded that Obergefell did not hold that every state law related to the marital relationship
    or the parent-child relationship must be “gender neutral.” Id. As the court in Treto observed, however, the
    Beaumont court’s opinion in In re A.E., which was decided in April of 2017, predated the Supreme Court’s holding
    in Pavan, which reached an opposite conclusion. Treto v. Treto, 
    622 S.W.3d 397
    , 401 n.2 (Tex.App.--Corpus
    Christi–Edinburg 2020, no pet.). We therefore conclude that Pavan impliedly disavowed this ruling.
    15
    spouses in same-sex marriages in establishing their maternity for children born during the
    marriage, as it does to male spouses in opposite-sex marriages in establishing their paternity. Id.
    at 402-03, citing Pavan, 
    137 S.Ct. at 2078
     (“under Pavan, we are to give effect to the ancillary
    benefits of a same–sex marriage, including the determination of maternity for the non–gestational
    spouse of a child born to the marriage”).
    The court therefore held that the non-gestational female spouse was the “presumed” parent
    of the child born during her same-sex marriage, and she could therefore not simply “walk away”
    from her responsibilities to the child simply because she was not its biological mother. 
    Id.
     at 402-
    03. In reaching this determination, the court observed that applying this presumption of parentage
    to spouses in same-sex marriages not only satisfies Pavan’s requirement of placing such spouses
    on equal footing with spouses in opposite-sex marriages, but also satisfies the policies of this state
    in promoting family stability and in protecting the interests of children through the enforcement of
    child support obligations.10 Id. at 401, citing In re J.W.T., 
    872 S.W.2d 189
    , 195 (Tex. 1994)
    (discussing history of marital presumption); Williams v. Patton, 
    821 S.W.2d 141
    , 145 (Tex. 1991)
    (recognizing that it is the “strong, long-standing policy of this state to protect the interests of its
    children,” which includes the policy of enforcing child support obligations).
    We agree with the court’s analysis in Treto in applying the presumption of parentage to
    same-sex spouses, and add the observation that applying the presumption promotes the long-
    standing principle that the “best interest of the child is always the primary consideration of the
    court in determining issues of conservatorship and possession of or access to a child.” See
    Doncer v. Dickerson, 
    81 S.W.3d 349
    , 353 (Tex.App.--El Paso 2002, no pet.), citing
    10
    The court in Treto also noted that other state courts that have adopted the Uniform Parentage Act have concluded
    that the marital presumption applies to non-gestational mothers in same-sex marriages. See Treto, 622 S.W.3d at
    401 (collecting cases).
    16
    TEX.FAM.CODE ANN. § 153.002. And in turn, it is presumed to be in a child’s best interest for
    parents to be appointed joint managing conservators, and to allow a child to have “frequent and
    continuing contact with parents who have shown the ability to act in the best interest of the child,
    and to encourage parents to share in the rights and duties of raising their children after the parents
    have separated or dissolved their marriage.” Id., citing TEX.FAM.CODE ANN. §§153.131(b);
    153.001; see also In re Mata, 
    212 S.W.3d 597
    , 604–05 (Tex.App.--Austin 2006, orig. proceeding),
    quoting Troxel v. Granville, 
    530 U.S. 57
    , 65 (2000) (“T]he interest of parents in the care, custody,
    and control of their children [ ] is perhaps the oldest of the fundamental liberty interests recognized
    by’ the courts.”).
    Unlike Treto, here we have a mother who has offered some testimony that she has already
    taken on the rights and responsibilities of raising and supporting a child born during her marriage,
    but has been denied the right to seek a conservatorship order from the court because she did not
    meet the gender-specific definitions of a “parent” as set forth in the Family Code. But just as the
    court in Treto would not allow the Code’s gender-specific definitions of a parent to be used as a
    shield to protect a female spouse in a same-sex marriage from the obligations owed to a child born
    of that marriage, so too, we will not allow those definitions to be used as a sword to prevent a
    spouse from asserting her rights as a parent. Accordingly, we conclude that Cristina can be
    considered the presumed parent of the child under section 160.201 of the Code, given her
    unrebutted testimony establishing that the child was born during her lawful marriage to Andrea.
    See TEX.FAM.CODE ANN. § 160.201(b)(1).
    C. The Code’s Assisted Reproduction Provisions
    Andrea, however, argues that even if we determine that Cristina can be considered the
    child’s presumed parent, the presumption was rebutted by Cristina’s own pleadings and testimony
    17
    in which she expressly acknowledged that she was not the child’s biological mother and was not
    genetically related to the child. Andrea points out that the Code provides that the presumption
    may be rebutted upon a determination that the presumed father is not genetically related to the
    child. See id. § 160.204(b)(1).11 And Andrea asserts that just as the presumption of paternity
    may be rebutted by establishing that a male spouse in an opposite-sex marriage is not genetically
    related to a child of his marriage, so too, any presumption of maternity should be rebutted by
    establishing that a female spouse in a same-sex marriage is not genetically related to a child of her
    marriage. She therefore argues that this refutes any claim that Cristina has to assert standing as a
    parent. We disagree.
    Andrea’s argument ignores section 160.703 of the Family Code, which expressly provides
    for times when spouses have agreed to conceive a child through means of “assisted reproduction.”
    Section 160.703—which like other sections in the Family Code—is gender specific, provides that
    when a “husband . . . consents to assisted reproduction by his wife as provided by Section 160.704,
    he is the father of a resulting child.” Id. § 160.703(a). Section 160.704 further provides that the
    husband’s consent may be reflected in a document signed by both the husband and wife and kept
    by a licensed physician, but that a husband’s failure to sign such a consent either “before or after
    the birth of the child does not preclude a finding that the husband is the father of a child born to
    his wife if the wife and husband openly treated the child as their own.” Id. § 160.704(a), (b).
    Although the language used in this provision seemingly only relates to situations involving
    11
    Section 160.204(b) provides that “A presumption of paternity established under this section may be rebutted only
    by: (1) an adjudication under Subchapter G; or (2) the filing of a valid denial of paternity by a presumed father in
    conjunction with the filing by another person of a valid acknowledgment of paternity as provided by Section 160.305.
    TEX.FAM.CODE ANN. § 160.204(b)(1)(2). Subchapter G provides that a “civil proceeding may be maintained to
    adjudicate the parentage of a child,” which includes genetic testing to determine a child’s paternity.
    TEX.FAM.CODE ANN. § 160.601 et seq.
    18
    opposite-sex spouses, for the same reasons that we construed the parental presumption provisions
    in a gender-neutral manner, so too we must interpret this provision in a gender-neutral manner in
    accordance with the holding in Pavan. Constitutionally, it must apply equally in determining
    parentage of a child born to a same-sex couple through assisted reproduction.
    Andrea, though, asserts that this Code provision—whether construed in a gender-neutral
    manner or not—is inapplicable to their situation because she was not artificially inseminated with
    help from a licensed physician, and was instead inseminated in a non-medical setting. In this
    regard, Andrea points out that the Family Code defines a “donor” as “an individual who provides
    eggs or sperm to a licensed physician to be used for assisted reproduction” and expressly provides
    that a “donor is not a parent of a child conceived by means of assisted reproduction.” Id.
    § 160.702. In turn, Andrea correctly argues that Luis cannot be considered a “donor” under the
    Code, given the non-medical setting in which the insemination took place, and that Luis was
    therefore “not excluded from the definition of parent under the Family Code.” In light of this
    provision, Luis could bring his own claim of paternity given his genetic relationship to the child.
    See In Interest of P.S., 
    505 S.W.3d 106
    , 110 (Tex.App.--Fort Worth 2016, no pet.) (individual who
    provided sperm to a “friend” for purposes of artificial insemination without the use of a licensed
    physician could not be considered a “donor” under the Family Code, and was therefore not
    prohibited from asserting his rights as the father).12
    But Luis’s right to claim paternity under these circumstances does not deprive Cristina of
    standing to bring a SAPCR petition, even though the insemination occurred in a non-medical
    12
    As discussed above, the unrebutted evidence presented at the temporary orders hearing demonstrated that the parties
    did not intend for Luis to have any parental rights, and he has not yet asserted any such rights, nor has he taken on any
    parental obligations to the child. However, if on remand he attempts to do so, we are confident the trial court will be
    able to resolve any such factual dispute regarding who the parties intended would be the child’s parents.
    19
    setting. Simply stated, the Code does not make this a requirement for determining a spouse’s
    parentage of a child born through such a procedure. As set forth above, the Code provides that a
    husband who has consented to “assisted reproduction” by his wife—either formally or
    informally—is considered the father of the “resulting child.” 
    Id.
     § 160.703. And, in turn, the
    Code defines “assisted reproduction” to mean “a method of causing pregnancy other than sexual
    intercourse,” to include, among other things, “intrauterine insemination.” Id. § 160.102(2)(A).
    The Code does not provide that the intrauterine insemination must be accomplished in a medical
    setting before a non-gestational spouse may assert his or her parental rights to a child born by such
    means during a marriage. In other words, the Code only addresses a donor’s right to bring a claim
    of paternity when the insemination occurs in a non-medical setting, and does not address the rights
    of the non-gestational spouse in this situation. See Treto, 622 S.W.3d at 400 (recognizing that the
    question of whether a donor can claim that he is a child’s parent is distinct from the question of
    whether a spouse has standing to assert her rights as a parent to a child conceived by artificial
    insemination in a same-sex marriage).
    We see no rational basis for concluding that a non-gestational spouse who consents to have
    her spouse artificially inseminated outside of a medical setting should be denied standing to bring
    a SAPCR petition seeking conservatorship over the child. To the contrary, under the plain
    language of the statute, if both spouses have signed a written consent document agreeing to the
    insemination, or if they have openly treated a child born through that method as their own after its
    birth, the trial court may still find that the non-gestational spouse is the parent of the child born in
    this way. Id. § 160.704(a), (b). We therefore conclude that the fact that Andrea was artificially
    inseminated in a non-medical setting does not alter Cristina’s standing to claim her status as a
    parent under the Code.
    20
    D. Cristina Did Not Waive Her Right to Claim That She Has Standing as a Parent
    We next turn to Andrea’s various arguments that Cristina waived her right to assert her
    standing as a parent under the Family Code, either due to pleading deficiencies, or her failure to
    preserve her “constitutional claims” for appellate review. And as well, we address the concurring
    opinion’s related concerns regarding the sufficiency of Cristina’s pleadings, together with the issue
    of whether Cristina should be estopped from asserting that she is the child’s mother in light of the
    agreed divorce decree’s statement that no children were born during the marriage.
    1. Cristina sufficiently alleged that she was a “parent” in her original pleadings
    Andrea argues that no matter how we interpret the Family Code, we should not consider
    Cristina’s argument that she has standing as the child’s “parent” for two procedural reasons. First,
    she contends that Cristina waived her to right to assert standing as the child’s parent, as she failed
    to allege that she was the child’s “parent” in any of her pleadings, or more particularly, the child’s
    “presumed parent,” and instead only alleged in her original and first amended petitions that she
    was the child’s “mother.” Second, she contends that Cristina dropped the allegation that she had
    standing as a parent in the second amended petition, and instead only alleged that she had standing
    as a person who previously had “care, control, and possession of the child” within the requisite
    time frames under the Code.
    The question of whether Cristina’s pleadings sufficiently alleged standing is a question of
    law that we review de novo. See Ryder Integrated Logistics, Inc. v. Fayette Cnty., 
    453 S.W.3d 922
    , 927 (Tex. 2015) (per curiam) (recognizing that appellate courts review jurisdiction and
    pleading sufficiency de novo).     In answering that question, we keep in mind that technical
    pleading rules do not carry the same weight in family law cases as they would in a typical civil
    case—family law cases are distinct because the “best interest” of the child is of paramount concern
    21
    in cases involving child custody and support issues. See Interest of S.G., No. 08-19-00008-CV,
    
    2020 WL 103971
    , at *5 (Tex.App.--El Paso Jan. 9, 2020, no pet.) (mem. op.), citing In re L.D.F.,
    
    445 S.W.3d 823
    , 832 (Tex.App--El Paso 2014, no pet.) (“In child custody cases, where the best
    interests of the child are the paramount concern, technical pleading rules are of reduced
    significance.”); Leithold v. Plass, 
    413 S.W.2d 698
    , 701 (Tex. 1967) (recognizing that technical
    rules of practice and pleadings are of little importance in determining issues on the custody of
    children).
    Under this relaxed standard, Cristina’s pleadings are not insufficient simply because she
    did not label herself as the child’s “parent” or “presumed parent,” or otherwise identify the Family
    Code provisions on which she asserted standing. To the contrary, by alleging that she was the
    child’s “mother” she sufficiently conveyed standing as the child’s “parent” under the Family Code.
    The Code expressly provides that a “mother” is included in the definition of a “parent.”
    TEX.FAM.CODE ANN. § 101.024(a). As well, standard dictionary definitions mirror this Code
    provision, defining a “mother” as a “female parent” of a child. See Mother, MERRIAM-WEBSTER,
    https://www.merriam-webster.com/dictionary/mother (last visited August 18, 2022).
    We also reject the suggestion that a child may only have one mother, and that Cristina as
    the non-gestational spouse may not use that term in her pleadings, based Pavan’s recognition that
    non-gestational spouses have a constitutional right to be recognized as the parents of a child born
    during a marriage. Pavan, 
    137 S. Ct. at
    2078–79. And to state the obvious, a child born into a
    same-sex marriage between two female spouses will necessarily have two “mothers” serving as
    parents. We therefore conclude that Cristina’s allegation that she has standing as the child’s
    “mother” was sufficient to allege standing under a gender-neutral and constitutionally mandated
    interpretation of the Family Code.
    22
    We also reject Andrea’s argument that Cristina cannot rely on the allegation that she has
    standing as a parent because she failed to include this allegation in her second amended petition.
    In support of her argument, Andrea relies on Rule 65 of the Texas Rules of Civil Procedure, for
    the proposition that Cristina’s second amended petition superseded earlier petitions, and that we
    may therefore only consider the allegations asserted there. However, we do not construe Rule 65
    so narrowly. Rule 65 provides that:
    Unless the substituted instrument shall be set aside on exceptions, the instrument
    for which it is substituted shall no longer be regarded as a part of the pleading in
    the record of the cause, unless some error of the court in deciding upon the necessity
    of the amendment, or otherwise in superseding it, be complained of, and exception
    be taken to the action of the court . . . .
    TEX. R. CIV. P. 65. Accordingly, under Rule 65, an amended petition typically supersedes the
    allegations made in the plaintiff’s original petition. See FKM P’ship, Ltd. v. Bd. of Regents of
    Univ. of Hous. Sys., 
    255 S.W.3d 619
    , 633 (Tex. 2008) (recognizing that causes of action not in an
    amended pleading are usually effectively dismissed when the amended pleading is filed); Mekeel
    v. U.S. Bank Nat. Ass’n, 
    355 S.W.3d 349
    , 354–55 (Tex.App.--El Paso 2011, pet. dism’d)
    (recognizing that the purpose of filing an amended petition is to add something to, or withdraw
    something from, what has been previously pleaded, and when an amended pleading is filed, it
    supplants all former pleadings). However, Rule 65 itself provides an exception when a party is
    complaining of “some error of the court in deciding upon the necessity of the amendment.” TEX.
    R. CIV. P. 65; see also Wells Fargo, N.A. v. Clower, No. 02-20-00058-CV, 
    2021 WL 4205056
    , at
    *6 n.12 (Tex.App.--Fort Worth Sept. 16, 2021, no pet.) (mem. op.) (recognizing that a “superseded
    pleading can still be regarded as part of the case if someone has complained about ‘some error of
    the court in deciding upon the necessity of the amendment’”); Kinney v. Palmer, No. 04-07-00091-
    CV, 
    2008 WL 2515696
    , at *2 (Tex.App.--San Antonio June 25, 2008, no pet.) (mem. op.), citing
    23
    TEX. R. CIV. P. 65 (recognizing exception).
    Cristina alleged in her original and first amended petitions that she had standing to bring a
    SAPCR petition as the child’s “mother.” However, in its order denying Cristina’s request for
    temporary orders, the trial court expressly ruled that Cristina did not have standing as a parent
    under the Family Code to bring her SAPCR petition.13 And in response to that ruling, Cristina
    requested permission to file an amended petition setting forth an alternative basis for standing—a
    request in effect caused by the trial court’s erroneous ruling that she lacked standing as a parent.
    And on appeal, Cristina is complaining of the trial court’s error in making that earlier ruling. We
    therefore conclude that the exception set forth in Rule 65 applies to allow Cristina to bring her
    challenge to the trial court’s ruling that she lacked standing as the child’s parent to bring a SAPCR
    as alleged in her earlier petitions.
    2. Cristina adequately raised her constitutional claims in the trial court
    Andrea contends that Cristina waived her right to bring her “constitutional challenge” to
    the gender-neutral provisions in the Family Code, because Cristina only raised her constitutional
    arguments orally during the temporary orders hearing and failed to raise them in a written pleading.
    In support of her waiver argument, Andrea relies on In re M.M.M., 
    428 S.W.3d 389
    , 397
    (Tex.App.--Houston [14th Dist.] 2014, pet. denied), in which our sister court held that a party
    could not raise a constitutional challenge to the validity of a statute on appeal because he failed to
    13
    The trial court’s order finding that Cristina lacked standing was made in denying Cristina’s request for temporary
    orders and was therefore not a final appealable judgment. See In re K.N.K., No. 05-10-01053-CV, 
    2011 WL 489932
    ,
    at *1 (Tex.App.--Dallas Feb. 14, 2011, no pet.); see also TEX.FAM.CODE ANN. § 105.001(e) (“Temporary orders
    rendered under this section are not subject to interlocutory appeal.”). Cristina might have challenged this ruling by a
    petition for writ of mandamus, but she could also challenge the ruling once the trial court entered a final judgment.
    See TEX.FAM.CODE ANN. § 109.001(b-5) (“A party may seek review of the trial court’s temporary order under this
    section by: (1) petition for writ of mandamus; or (2) proper assignment in the party’s brief.”); see also In re Moore,
    
    511 S.W.3d 278
    , 286 (Tex.App.--Dallas 2016, no pet.) (recognizing that a party may review a finding in a temporary
    order as part of a “pending appeal from the final judgment”).
    24
    raise the issue in written pleadings in the trial court, and that raising the issue orally at a hearing
    could not preserve the challenge. In that case, however, the party was appealing from an order
    granting summary judgment, and Rule 166a(c) of the Texas Rules of Civil Procedure specifically
    provides that in summary judgment proceedings, “Issues not expressly presented to the trial court
    by written motion, answer or other response shall not be considered on appeal as grounds for
    reversal (emphasis added).”       TEX.R.CIV.P. 166a(c); In re M.M.M., 428 S.W.3d at 397
    (recognizing that even constitutional challenges not expressly presented to the trial court by written
    motion, answer, or other response in a summary judgment proceeding will not be considered on
    appeal as grounds for reversal). Here, the trial court’s ruling was not made in the context of a
    summary judgment proceeding. Instead, as set forth above, the trial court entered its ruling
    finding that Cristina lacked standing in response to an oral motion for directed verdict that Andrea
    made during the midst of the temporary orders hearing.             Accordingly, Rule 166a’s strict
    requirement that all issues must be presented in writing in the trial court is inapplicable.
    Instead, we apply the general preservation rule set forth in Rule 33.1(a) of the Texas Rules
    of Appellate Procedure, which provides that a party may preserve an issue for appellate review by
    presenting it to the trial court in a “timely request, motion, or objection,” and by obtaining either
    an express or implied ruling on the issue. TEX.R.APP.P. 33.1(a)(1)(A),(2)(A). And Rule 33.1
    has no requirement that a party must raise an issue in writing to preserve it for appellate review;
    courts have held that a party may preserve error under this rule by raising an issue through oral
    objection. See Wright v. State Farm Lloyds, No. 03-20-00384-CV, 
    2022 WL 567860
    , at *2
    (Tex.App.--Austin Feb. 25, 2022, no pet.) (mem. op.) (party preserved error where counsel
    verbally argued issue during a hearing in response to opposing party’s motion for sanctions,
    finding that counsel’s argument constituted a sufficient “complaint,” “request,” or “objection” to
    25
    satisfy the requirements of Rule 33.1), citing Van Es v. Frazier, 
    230 S.W.3d 770
    , 775–76
    (Tex.App.--Waco 2007, pet. denied) (party preserved error for appellate review where he
    presented his grounds in opposition to a request for sanctions “in written responses and/or in
    arguments presented in the hearings”); see also Tex. Dep’t of Protective & Regul. Servs. v. Sherry,
    
    46 S.W.3d 857
    , 861 (Tex. 2001) (holding that purported father did not preserve his constitutional
    claim to standing in paternity case when he neither asserted his constitutional claims in his trial
    court pleadings or at the trial court hearing on standing).        We thus conclude that Cristina
    sufficiently preserved her constitutional issues by arguing these issues at the temporary orders
    hearings. In fact, it was Andrea who first raised the issue at the hearing by making her oral motion
    for directed verdict claiming that Cristina did not meet the definition of a parent under the Family
    Code. And Cristina responded in kind by arguing—just as she does on appeal—that the Family
    Code must be interpreted in a constitutionally-sound and gender-neutral manner under the
    Supreme Court’s holdings in Obergefell and its progeny to permit same-sex spouses in to assert
    their rights as parents just as opposite-sex spouses have a right to do under the Code. And in turn,
    the trial court impliedly rejected this argument when it concluded that Cristina lacked standing as
    a “parent” under the Code.
    Accordingly, for the reasons set forth above, we conclude that Cristina did not waive her
    right to challenge the trial court’s ruling that she lacked standing as a parent under the Family Code
    to bring her SAPCR petition. And because we conclude that Cristina did in fact have standing
    under the Code to bring her SAPCR petition, we conclude that the trial court erred in dismissing
    her petition.
    26
    3. Cristina was not required to bring an independent suit to adjudicate her
    parentage
    Although not raised by Andrea, the concurring opinion faults Cristina for not expressly
    requesting an “adjudication” of her parentage under the UPA in her SAPCR petition, and for
    instead only requesting a conservatorship and support order. As the argument goes, this failure
    means that Cristina lacks standing to bring her SAPCR petition on that basis alone.
    But we disagree that Cristina was required to expressly seek an “adjudication” of her
    parentage under the UPA as a prerequisite for asserting standing as a parent in her SAPCR petition.
    The UPA provides that a party may bring an independent civil suit seeking the adjudication of his
    or her parentage of a child.     See TEX.FAM.CODE ANN. § 160.601(a) (providing that “civil
    proceeding may be maintained to adjudicate the parentage of a child”). However, the Code
    provides that a party may also bring an original SAPCR seeking conservatorship and support of a
    child and allows for at least two situations in which a man may bring such a petition before having
    his parentage established.     First, a “presumed father” may bring a SAPCR seeking a
    conservatorship order regarding a child born during a marriage, and is entitled to have his rights
    determined in that proceeding without the need to file an independent adjudication proceeding
    under the UPA. See Ortiz v. Hernandez, No. 14-11-01031-CV, 
    2012 WL 5988847
    , at *1-2
    (Tex.App.--Houston [14th Dist.] Nov. 29, 2012, no pet.) (mem. op.) (holding that a presumed
    father had standing under section 102.003 of the Code to pursue a SAPCR seeking custody of child
    born during his marriage to mother, even though he was time-barred from seeking to adjudicate
    his parentage under the UPA). Similarly, section 102.003(8) gives standing to a “man alleging
    himself to be the father of a child.” TEX.FAM.CODE ANN. § 102.003(8). In that event, a trial court
    has the authority to determine the man’s status as a father, without the need to file an independent
    27
    UPA adjudication proceeding. See In re K.I.A., 
    205 S.W.3d 14
    , 15-16 (Tex.App.--Eastland 2006,
    no pet.) (finding that a man who alleged that he was a child’s biological father had standing under
    section 102.003(a)(8) to bring a SAPCR petition seeking a conservatorship order, and trial court
    had the authority to adjudicate his rights in that proceeding); In re J.H., No. 02-20-00366-CV,
    
    2021 WL 733083
    , at *2 (Tex.App.--Fort Worth Feb. 25, 2021, no pet.) (mem. op.) (man alleging
    himself to be father of child had standing to bring a SAPCR petition under section 102.003(a)(8)
    seeking conservatorship of child, as well as an independent adjudication proceeding under the
    UPA). Applying a gender-neutral interpretation of these provisions, it follows that if a man
    contending that he is a child’s father has the opportunity to have his rights determined in an original
    SAPCR proceeding, so too should a woman be afforded that same opportunity.
    Our sister court’s holding in Interest of N.M.B., No. 04-18-00111-CV, 
    2018 WL 6516120
    ,
    at *2 (Tex.App.--San Antonio Dec. 12, 2018, pet. denied) (mem. op.) does no violence to this
    conclusion. In N.M.B., the appellant, who had been in a same-sex (unmarried) relationship with
    the appellee, brought an original SAPCR proceeding seeking a custody and support order for a
    child born during the relationship through means of artificial insemination. She alleged standing
    as the “intended parent” of the child. Id. at *1. The court observed, however, that at the time of
    the lawsuit, the Code only gave an “intended parent” the right to bring a suit to adjudicate parentage
    under the UPA. 14 Id. at *2, citing TEX.FAM.CODE ANN. § 160.602(8) (“[A] proceeding to
    adjudicate parentage may be maintained by . . . a person who is an intended parent.”). And,
    significantly, although section 102.003 of the Code was later amended to give standing to certain
    categories of “intended parents” to bring an original SAPCR proceeding, at the time it did not. Id.
    14
    The UPA defines the term “intended parents” to mean “individuals who enter into an agreement providing that the
    individuals will be the parents of a child born to a gestational mother by means of assisted reproduction, regardless of
    whether either individual has a genetic relationship with the child.” TEX.FAM.CODE ANN. § 160.102(9).
    28
    Given the prior Code’s failure to recognize an “intended parent” as an individual with standing to
    bring an original SAPCR petition, the court in N.M.B. therefore affirmed the trial court’s decision
    to dismiss the SAPCR petition for lack of standing. Id.
    The opinion in N.M.B. was therefore based solely on the fact that the Code at the time did
    not grant “intended parents” standing to bring an original SAPCR petition. In contrast, Cristina
    brought her original SAPCR petition based on her allegation that she had standing as the parent of
    a child born during her legal marriage to Andrea—a category expressly recognized by section
    102.003(1) of the Code. We therefore find nothing in the opinion in N.M.B., or elsewhere in the
    Texas Family Code, that would prohibit Cristina from asserting standing as the child’s parent in
    her SAPCR proceeding, and to have her rights determined in that proceeding.
    4. The impact of the parties’ divorce decree
    The concurring opinion raises a second issue that is not addressed by the parties in their
    briefing—whether Cristina should be estopped from asserting her standing as a parent due to the
    statement the parties made in their agreed-divorce decree that no child was born during the parties’
    marriage.
    Andrea did not properly raise an estoppel issue in the trial court, nor did the trial court rely
    on an estoppel theory in reaching its decision to dismiss Cristina’s SAPCR petition. If Andrea
    had wished to assert that Cristina was judicially estopped from claiming that a child was born
    during the marriage based on their divorce proceedings, she was required to raise the issue of
    estoppel as an affirmative defense in her pleadings, which she failed do.15 See Burket v. Delaware
    Drilling Corp., 
    435 S.W.2d 307
    , 308–09 (Tex.App.--El Paso 1968, writ dism’d), citing TEX. R.
    15
    Judicial estoppel is a common law doctrine utilized to prevent a party from asserting a claim in a legal proceeding
    that is inconsistent with position taken by that party in a previous proceeding. Garcia v. BNSF Ry. Co., 
    387 S.W.3d 763
    , 767 (Tex.App.--El Paso 2012, no pet.).
    29
    CIV. P. 94 (providing that a party shall set forth in a pleading all affirmative defenses); see also
    Anadarko Petroleum Corp. v. Thompson, 
    94 S.W.3d 550
    , 553 (Tex. 2002) (recognizing judicial
    estoppel as an affirmative defense). As such, it is not a defense that is properly before us. See
    Neeley v. Sw. Inv. Co., 
    430 S.W.2d 465
    , 469 (Tex. 1968) (appellate court “could not properly
    render judgment on the basis of an affirmative defense which had not been urged in the trial
    court”); In re Estate of Dillard, 
    98 S.W.3d 386
    , 396 (Tex.App.--Amarillo 2003, pet. denied) (claim
    of judicial estoppel was waived where party failed to affirmatively plead it as a defense); Gulf
    States Abrasive Mfg., Inc. v. Oertel, 
    489 S.W.2d 184
    , 186 (Tex.Civ.App.--Houston [1st Dist.]
    1972, writ ref’d n.r.e.) (same).
    Nor does our record support the argument. At the hearing on the temporary orders,
    Cristina testified that due to their “confusion,” she and Andrea submitted a pro se agreed divorce
    decree to the trial court for signature, in which they stated that there were no children born during
    the marriage. At another hearing, Andrea’s attorney made statements indicating that Cristina had
    filed a bill of review in the divorce case, presumably to clarify that a child had in fact been born
    during the marriage, and further indicated her belief that the trial court had ruled upon the bill.
    However, that ruling does not appear in the record, and there is nothing in the appellate record to
    indicate how the trial court ruled on the bill of review, nor have the parties asked us to take judicial
    notice of the proceedings in which the bill was considered.
    We also sense a finality problem with a divorce decree where the parties failed to inform
    the trial court of the existence of a child born during the marriage. The Family Code expressly
    provides that during a divorce proceeding, the parties must disclose the names and identities of
    any children born during the marriage so that the trial court may determine the parties’ support
    obligations. See TEX.FAM.CODE ANN. § 6.406(a) (“The petition in a suit for dissolution of a
    30
    marriage shall state whether there are children born or adopted of the marriage who are under 18
    years of age or who are otherwise entitled to support as provided by Chapter 154.”). In effect,
    this requirement amounts to a mandatory joinder of a divorce proceeding with a SAPCR
    proceeding to determine support obligations that the parents might have to the children. When
    the parties do not include a required SAPCR in the divorce proceeding, any resulting divorce
    decree cannot be considered final.16 See, e.g., Diaz v. Diaz, 
    126 S.W.3d 705
    , 708 (Tex.App.--
    Corpus Christi–Edinburg 2004, no pet.); In Interest of B.T.G., 
    494 S.W.3d 839
    , 843–44 (Tex.App.-
    -Dallas 2016, no pet.) (where SAPCR was improperly separated from divorce, the
    divorce decree was “interlocutory,” preventing appellate court from addressing any issues in the
    divorce proceedings, and instead warranting a remand of the proceedings to the trial court); see
    also Brown v. Brown, 
    917 S.W.2d 358
    , 361 (Tex.App.--El Paso 1996, no writ) (McClure, J.
    concurring) (collecting cases for the proposition that “[d]ivorce decrees which reserve issues of
    child support are not accorded the presumption of finality”).
    Stated otherwise, a divorce decree that mistakenly states that no children were born during
    the marriage, or which fails to include all the children who were born during the marriage, cannot
    be considered final. See Clark v. Clark, 
    196 S.W.2d 343
    , 345 (Tex.App.--Texarkana 1946, no
    writ) (where husband sought and obtained a default judgment in a divorce proceeding, which
    erroneously stated that no children had been born during the marriage, the decree could not be
    considered final where the wife later filed a motion for new trial and came forward with evidence
    that a child was in fact born during the marriage); see also Hawkins v. Hawkins, 
    999 S.W.2d 171
    ,
    16
    In fact, at least one court has held that the parties’ failure to follow the Code’s mandatory joinder requirements
    renders a divorce decree void. See, e.g., Soliz v. Soliz, No. 13-02-010-CV, 
    2003 WL 21025900
    , at *2 (Tex.App.--
    Corpus Christi–Edinburg May 8, 2003, no pet.) (mem. op.), citing Daniels v. Daniels, 
    45 S.W.3d 278
    , 282 (Tex.App.-
    -Corpus Christi 2001, no pet.).
    31
    177 (Tex.App.--Austin 1999, no pet.) (where wife obtained a default judgment in divorce
    proceeding, but only disclosed the existence of three of the four children born during the marriage,
    husband was entitled to reopen the divorce decree to address paternity and support issues for the
    fourth child); Gonzalez v. Gonzalez, 
    177 S.W.2d 328
    , 329, 331 (Tex.App.--El Paso 1943, no writ)
    (husband’s divorce petition was “insufficient” to support a divorce decree where the petition only
    provided the court with information regarding two of the three children that were born during the
    marriage). Here, the unrebutted evidence demonstrated that Andrea gave birth to a child during
    her marriage to Cristina (regardless of who the other parent might be), yet the parties failed to
    disclose the child’s existence to the court during the divorce proceeding and failed to include a
    SAPCR to address custody and support issues as required by the Family Code. Accordingly, the
    parties’ divorce decree cannot be considered final for the purpose of giving conclusive effect on
    any issues pertaining to the undisclosed child.
    For similar reasons, we reject any assertion that the UPA requires us to treat the divorce
    decree as being a “final adjudication” that no child was born during the parties’ marriage. Section
    160.637 of the UPA provides that “a determination of parentage is binding on . . . all parties to an
    adjudication by a court acting under circumstances that satisfy the jurisdictional requirements of
    Section 159.201,” (i.e., relating to out-of-state parties).              See TEX.FAM.CODE ANN.
    § 160.637(a)(2). One might read this section to say that if a divorce decree makes a finding that
    there were no children of the marriage, it becomes a conclusive adjudication of parentage (or more
    particularly, non-parentage). That argument, however, overlooks section 160.637 of the UPA,
    which provides that “in a proceeding to dissolve a marriage, the court is considered to have made
    an adjudication of the parentage of a child if “the final order: (1) expressly identifies the child as
    ‘a child of the marriage’ or ‘issue of the marriage’ or uses similar words indicating that the husband
    32
    is the father of the child; or (2) provides for the payment of child support for the child by the
    husband unless paternity is specifically disclaimed in the order.”                          TEX.FAM.CODE ANN.
    § 160.637(c). Here, however, although there is no doubt that a child was born during the
    marriage, the parties’ divorce decree failed to identify the existence of the child and did not provide
    for the payment of child support.              Consequently, the divorce court did not make a “final
    adjudication” with respect to any parentage issues.17
    Here, the limited evidence in our record suggests that during their divorce proceedings,
    Andrea and Cristina took two improper actions. First, they failed to disclose the existence of a
    child that was admittedly born during their marriage and failed to initiate a SAPCR proceeding
    that would have allowed the court to determine custody and support issues during their divorce
    proceeding, as required by the Family Code. Second, they entered into a private agreement
    regarding custody and support issues pertaining to the child, without seeking court approval. As
    explained above, however, their improper unilateral actions in avoiding the entry of a formal
    SAPCR order cannot alter the existence of a support duty, nor should their actions prohibit a court
    from entering an appropriate conservatorship and support order to address the child’s needs now
    that her existence has come to light. And given our conclusion that Cristina has standing to bring
    a SAPCR petition as a presumed parent under a gender-neutral interpretation of the Family Code
    to seek such an order, we cannot allow the errors that occurred in the earlier divorce proceeding to
    stand in her way.
    17
    And were it otherwise, we would be sanctioning the parties’ ability fail to disclose to the court the existence of
    children born to the marriage when obtaining a court sanctioned divorce. That in turn would frustrate the legislative
    policy of protecting the interests of children, which includes the policy of establishing and enforcing child support
    obligations. See Treto, 622 S.W.3d at 402, citing Williams, 821 S.W. 2d at 145 (recognizing that the Code expressly
    requires that all parental agreements concerning child support be approved by the court, which can accept or reject the
    agreement depending on whether or not it is in the child’s best interest), citing TEX.FAM.CODE ANN. § 14.06(a)–(d)
    (repealed 1995) (recodified at TEX.FAM.CODE ANN. § 154.124) (requiring court approval of agreements pertaining to
    child support to ensure that any such agreements are in the child’s best interest).
    33
    Cristina’s Issue One is sustained.
    V. CONCLUSION
    In conclusion, although we express no opinion on the merits of Cristina’s claim to be
    appointed the conservator of the child born during the parties’ same-sex marriage, we simply hold
    that she can exercise her constitutional right to assert that claim and to have her day in court. We
    therefore reverse the trial court’s judgment dismissing Cristina’s SAPCR petition, and remand this
    matter to the trial court for further proceedings in accordance with our opinion. Because we
    reverse on Cristina’s first issue, we find it unnecessary to consider her second issue.
