    PATRICIA H. PARKS MONTEITH
    v.
    GEORGE H. MONTEITH JR.
    GORMAN, J.
    [¶1] Patricia H. Parks Monteith appeals from a judgment of the District
    Court (Portland, Cashman, J.) declining Patricia’s request to register in Maine a
    child support order issued in Maryland against George H. Monteith Jr. as to the
    parties’ four children. Patricia contends that the court erred by concluding that,
    because the Maryland court lacked subject matter jurisdiction to enter the
    order, it cannot be registered for enforcement in Maine. We disagree and affirm
    the judgment.
    [¶2] This matter requires us to interpret, for the first time, certain
    provisions of the Uniform Interstate Family Support Act (UIFSA), 19-A M.R.S.
    §§ 2801-3401 (2021). To place the events of the present matter and the parties’
    arguments in some context, we begin with the background of UIFSA.
    2
    [¶3]       UIFSA was promulgated by the National Conference of
    Commissioners on Uniform State Laws (NCCUSL)1 in 1992 to create a uniform
    national system for the issuance, enforcement, and modification of child and
    spousal support. UIFSA cmt., Prefatory Note(I)-(II), included with L.D. 986
    (121st Legis. 2003); In re Ball, 
    123 A.3d 719
    , 723 (N.H. 2015).                             In 1996,
    Congress mandated that enactment of UIFSA was a precondition to states’
    eligibility for obtaining federal grant money to fund child and spousal support
    programs. Child Care and Development Block Grant Amendments of 1996,
    Pub. L. No. 104-193, 
    110 Stat. 2105
     (codified as amended at 
    42 U.S.C.S. § 666
    (f)
    (LEXIS through Pub. L. No. 117-26, approved July 6, 2021)). By 1998, all fifty
    states had adopted UIFSA—Maine in 1993, P.L. 1993, ch. 690, §§ A-2, A-3
    (effective July 1, 1995), and Maryland in 1996, 
    1996 Md. Laws 667
    .2 See UIFSA
    cmt., Prefatory Note(I); Ball, 123 A.3d at 723.
    [¶4] The hallmark of UIFSA is the “one-order system,” by which a child
    support order issued in one state is enforceable in every other state, but which
    prevents any other state from modifying that order except in limited
    circumstances, all for the purposes of eliminating competing child support

    [¶5] A person may seek registration of an issuing court’s child support
    order in the appropriate court of any other state for enforcement and/or
    modification. 19-A M.R.S. §§ 3150-3153, 3251-3256; 
    Md. Code Ann., Family Law §§ 10-340
     to 10-343, 10-348 to 10-353 (LEXIS through legis. effective
    June 1, 2021, of the 2021 Reg. Sess. of the Gen. Assembly). Registration occurs
    upon the petitioning party’s submission of certain documentation to the court
    of the registering state. 19-A M.R.S. §§ 3151, 3152(1); 
    Md. Code Ann., Family Law §§ 10-341
    , 10-342(a); see Hawley v. Murphy, 
    1999 ME 127
    , ¶ 9, 
    736 A.2d 268
    .
    4
    [¶6] Once such an order is registered, the nonregistering party may
    challenge the validity or enforcement of the registered order and request a
    hearing, at which it is the nonregistering party’s burden to prove one or more
    of eight possible defenses, among them, that “[t]he alleged controlling order is
    not the controlling order.” 19-A M.R.S. §§ 3201, 3202, 3203(1)(H); 
    Md. Code Ann., Family Law §§ 10-344
    , 10-345, 10-346(a)(8) (LEXIS through legis.

    , ¶ 9, 
    736 A.2d 268
    ; Brenckle, 675 N.E.2d at 394.
    [¶7] If the nonmoving party does not object to the registration of the
    order, or if the nonmoving party does not successfully prove at least one of the
    defenses, the registration of the order is confirmed and the registered order
    may then be enforced in the new state as if it were the issuing state. 19-A M.R.S.
    §§ 3153(3), 3202(2), 3203(3), 3204; 
    Md. Code Ann., Family Law §§ 10-343
    (c),
    10-345(b), 10-346(c), 10-347 (LEXIS through legis. effective June 1, 2021, of

    1999 ME 127
    , ¶ 9, 
    736 A.2d 268
    .
    [¶8] Notwithstanding the broad powers to enforce a child support order
    in every state, UIFSA circumscribes the ability of other states to modify the
    initial order. See 19-A M.R.S. § 3152(3) (“Except as otherwise provided in this
    5
    chapter, a tribunal of this State shall recognize and enforce, but may not modify,
    a registered support order if the issuing tribunal had jurisdiction.”); 
    Md. Code Ann., Family Law § 10-342
    (c); Ball, 123 A.3d at 723; Cohen v. Cohen, 
    25 N.E.3d 840
    , 845 (Mass. 2015). It sets out the general rule that when an issuing state
    enters a child support order, the issuing state retains continuing, exclusive
    jurisdiction to modify that order:
    1. Tribunal has continuing, exclusive jurisdiction. A
    tribunal of this State that has issued a support order consistent
    with the laws of this State has and shall exercise continuing,
    exclusive jurisdiction to modify its child support order if the order
    is the controlling order and:
    A. At the time of the filing of a request for modification this
    State is the residence of the obligor, the individual obligee or
    the child for whose benefit the support order is issued; or
    B. Even if this State is not the residence of the obligor, the
    individual obligee or the child for whose benefit the support
    order is issued, the parties consent in a record or in open
    court that the tribunal of this State may continue to exercise
    jurisdiction to modify its order.
    19-A M.R.S. § 2965(1); see 
    Md. Code Ann., Family Law § 10-308
    (a) (LEXIS
    through legis. effective June 1, 2021, of the 2021 Reg. Sess. of the Gen.
    Assembly); UIFSA cmt. to 19-A M.R.S. § 2965, included with L.D. 986 (121st
    Legis. 2003) (calling this section “the most crucial provision in UIFSA”). The
    Act identifies only three circumstances in which the continuing, exclusive
    6
    jurisdiction to modify the child support order passes from the issuing state to
    another state:
    [¶9] First, pursuant to 19-A M.R.S. § 3255(1), “[i]f all of the parties who
    are individuals reside in [the modification state] and the child does not reside
    in the issuing state, a tribunal of [the modification state] has jurisdiction to
    enforce and to modify the issuing state’s child support order in a proceeding to
    register that order.” Accord 
    Md. Code Ann., Family Law § 10-352
    (a).
    [¶10] Second, if section 3255(1) does not apply, jurisdiction passes to
    the modification state when
    (1) Neither the child, nor the obligee who is an individual, nor the
    obligor resides in the issuing state;
    (2) A petitioner who is a nonresident of [the modification state]
    seeks modification; and
    (3) The respondent is subject to the personal jurisdiction of the
    tribunal of [the modification state].
    19-A M.R.S. § 3253(1)(A)(1)-(3); accord 
    Md. Code Ann., Family Law § 10-350
    (a)(1)(i)-(iii); Bowman v. Bowman, 
    917 N.Y.S.2d 379
    , 382 (N.Y. App.
    Div. 2011). Notably, a transfer of jurisdiction pursuant to either of these first
    two circumstances does not involve any notice to or action in the issuing court
    but is instead based solely on the residence of the parties and the child and on
    the personal jurisdiction of the modification court.
    7
    [¶11] Third, jurisdiction to modify passes when “[the modification state]
    is the residence of the child, or a party who is an individual is subject to the
    personal jurisdiction of the tribunal and all of the parties who are individuals
    have filed consents in a record in the issuing tribunal for a tribunal of [the
    modification state] to modify the support order and assume continuing,
    exclusive jurisdiction.” 19-A M.R.S. § 3253(1)(B); accord 
    Md. Code Ann., Family Law § 10-350
    (a)(2); see 19-A M.R.S. § 2802(13-B) (defining “[r]ecord” as
    “information that is inscribed on a tangible medium or that is stored in an
    electronic or other medium and is retrievable in perceivable form”); Ball,
    123 A.3d at 723-24.           This consent requirement is echoed in 19-A M.R.S.
    § 2965(2)(A), by which the issuing state is precluded from exercising
    continuing, exclusive jurisdiction if “[a]ll of the parties who are individuals file
    consent in a record with the tribunal of [the issuing state] that a tribunal of
    another state that has jurisdiction over at least one of the parties who is an
    individual or that is located in the state of residence of the child may modify the
    order and assume continuing, exclusive jurisdiction.”3 Accord Md. Code Ann.,
    3   The issuing state’s exercise of continuing, exclusive jurisdiction is also precluded when “the
    [issuing state] tribunal’s order is not the controlling order,” that is, when an intervening order was
    properly issued after the order of which a party seeks modification. 19-A M.R.S. § 2965(2)(B) (2021);
    accord 
    Md. Code Ann., Family Law § 10-308
    (b)(2) (LEXIS through legis. effective June 1, 2021, of the
    2021 Reg. Sess. of the Gen. Assembly); see 19-A M.R.S. § 2967(2) (2021); Md. Code Ann., Family Law
    8
    Family Law § 10-308(b)(1) (LEXIS through legis. effective June 1, 2021, of the
    2021 Reg. Sess. of the Gen. Assembly).                          These two provisions are
    complementary—section 2965 detailing for the issuing court how it is divested
    of modification jurisdiction and section 3253 detailing for the modification
    court how it obtains modification jurisdiction. See 
    Md. Code Ann., Family Law §§ 10-308
    (b)(1), 10-350(a)(2).
    [¶12]      Unlike the first and second circumstances for a transfer of
    continuing, exclusive jurisdiction, this third circumstance requires action
    involving the issuing court, i.e., the filing of the parties’ consent to the
    modification court’s exercise of jurisdiction “in a record with the tribunal of
    [the issuing state].” 19-A M.R.S. § 2965(2)(A); accord 
    Md. Code Ann., Family Law § 10-308
    (b)(1). The consent requirement is thus plainly imposed when
    the issuing court would otherwise retain continuing, exclusive jurisdiction over
    the matter because one of the parties or the child continues to live in the issuing
    state. See 19-A M.R.S. § 2965(1)(A); Md. Code Ann. § 10-308(a)(1).

    I. BACKGROUND
    [¶13] On June 3, 2019, the Department of Health and Human Services4
    filed in the Maine District Court an affidavit and request for registration of a
    Maryland child support order on behalf of Patricia against George. See 19-A
    M.R.S. § 3001(1-A). That day, the court clerk issued a notice of registration of
    the order pursuant to 19-A M.R.S. § 3201. George challenged the registration
    of the Maryland order, requesting a hearing and asserting five defenses,
    including that the Maryland court lacked jurisdiction to issue its order, which
    would mean that the Maryland order was “not the controlling order.”
    19-A M.R.S. § 3203(1)(H); see 19-A M.R.S. §§ 3201(2)(B), 3202.
    [¶14] After a testimonial hearing, by order dated September 16, 2020,
    the court made the following findings, which are supported by competent
    record evidence and which the parties do not dispute. See Boyd v. Manter, 
    2018 ME 25
    , ¶ 9, 
    179 A.3d 906
    . In 2002, Patricia and George were divorced in Maine
    by a decision of the District Court (Biddeford, Stavros, CMO), which contained,
    inter alia, a provision requiring George to pay child support to Patricia for the
    4 Although the Department filed the initial affidavit and request for registration, it was excused
    from the case during the hearing and is not participating in the present appeal.
    10
    parties’ four children, who were then minors. At some point, Patricia and the
    children moved to Maryland, and George remained in Maine.
    [¶15] Roughly ten years after the divorce, and after their oldest child had
    turned eighteen, Patricia initiated a proceeding in Maryland, seeking
    modification of the Maine child support order. In the Maryland modification
    action, neither party filed a consent in Maine to the Maryland court’s exercise
    of jurisdiction to modify the Maine order. See 19-A M.R.S. § 2965(2)(A); 
    Md. Code Ann., Family Law § 10-308
    (b)(1). Nevertheless, George did appear and
    participate in the Maryland modification proceedings, which culminated in the
    entry of an agreed-to modified child support order. That order purported to
    increase George’s child support obligation for the three remaining minor
    children. It is this modified Maryland order that Patricia now seeks to enforce
    in the current registration action. George did not pay the amounts imposed in
    the modified Maryland order; instead, he continued to pay in accordance with
    the terms of the original Maine order. George has paid all child support sums
    due pursuant to the 2002 Maine order; the arrearage that Patricia claims—
    totaling $48,245.75—is for the additional amounts due only pursuant to
    Maryland’s 2013 modification order.5
    5   The last of the parties’ minor children turned eighteen early in 2019.
    11
    [¶16] The District Court concluded that the Maryland order was void
    ab initio based on the parties’ failure to file the required consents in Maine to
    the Maryland court’s exercise of jurisdiction, and it therefore vacated the
    registration of the Maryland order on that basis. On Patricia’s motion for
    findings of fact and for reconsideration, the court also determined that George
    had not waived his right to object to enforcement of the Maryland support
    order. Patricia appeals.
    II. DISCUSSION
    [¶17] Three different child support events occurred in this matter:
    (1) Patricia obtained a child support order in Maine in 2002; (2) Patricia sought
    registration of the 2002 Maine order in Maryland and then obtained a
    modification of the Maine order in Maryland in 2013; and (3) in 2019, Patricia
    sought registration of the 2013 Maryland order in Maine for purposes of
    enforcing the additional Maryland-imposed obligations.
    A.    Maine Proceedings in 2002
    [¶18] There is no dispute that Patricia, George, and the children all lived
    in Maine when the Maine District Court issued the initial child support order in
    2002; that the District Court entered the initial order consistent with Maine
    law; and that the 2002 order was the only child support order then in existence.
    12
    See 19-A M.R.S.A. §§ 1653(8), 2001-2009 (1998);6 19-A M.R.S. § 3153(1)
    (stating that the “law of the issuing state . . . governs”); MacDougall v. Dep’t of
    Hum. Servs., 
    2001 ME 64
    , ¶ 8, 
    769 A.2d 829
     (“Pursuant to UIFSA, the law of the
    state that issued the divorce decree governs the nature, extent, amount, and
    duration of the support obligation and payment of arrearages under the
    order.”); see also 4 M.R.S. § 152(11) (2021); 19-A M.R.S. § 103 (2021) (setting
    out the District Court’s jurisdiction as to child support). Thus, according to the
    plain language of section 2965(1)(A), Maine had continuing, exclusive
    jurisdiction to modify the 2002 child support order.
    B.       Maryland Modification Proceedings
    [¶19] In 2013, Patricia obtained a modification of the Maine order in
    Maryland, where she and the children lived. Because there is no dispute that
    George, the obligor, was still a resident of Maine, however, neither the first nor
    the second circumstance for the transfer of continuing, exclusive jurisdiction
    could apply. See 19-A M.R.S. §§ 3253(1)(A), 3255(1); 
    Md. Code Ann., Family Law §§ 10-350
    (a)(1), 10-352(a); supra ¶¶ 9-10; see also 19-A M.R.S. § 2802(13)
    (defining “[o]bligor”). Maryland could therefore obtain jurisdiction to modify
    Maine’s child support statutes have been amended on several occasions since 2002, but these
    6
    amendments are not relevant to the current appeal. E.g., P.L. 2007, ch. 142, § 1 (effective Sept. 2,
    2007).
    13
    Maine’s 2002 order—and Maine could be divested of that jurisdiction—only if
    the parties consented to the Maryland court’s exercise of jurisdiction according
    to the third circumstance, that is, by filing “consents in a record in the issuing
    tribunal” in Maine. 
    Md. Code Ann., Family Law § 10-350
    (a)(2); see 19-A M.R.S.
    § 2965(2)(A); accord 19-A M.R.S. § 3253(1)(B); 
    Md. Code Ann., Family Law § 10-308
    (b)(1). It is undisputed, however, that neither Patricia nor George filed
    in Maine a consent to the Maryland court’s exercise of jurisdiction. The
    question presented in this case is what the consequence is of Patricia and
    George’s failure to comply with section 2965(2)(A).
    C.    Maine Proceedings in 2019
    [¶20] In 2019, after George failed to comply with the Maryland order,
    Patricia sought registration and enforcement of the Maryland order in Maine.
    The District Court concluded that the failure to file consents in Maine deprived
    the Maryland court of jurisdiction to modify the child support order, that is, that
    Maine had retained its continuing, exclusive jurisdiction over the parties’ child
    support as a matter of law. Thus, when Patricia sought to register the Maryland
    order for enforcement in Maine, the court declined to do so based on the
    conclusion that the Maryland order was void, having been issued without the
    required Maine consents, and therefore, George met his burden of establishing
    14
    that the Maryland order was “not the controlling order” pursuant to section
    3203(1)(H).
    [¶21] Patricia argues that this conclusion was error. Although she
    concedes that filing the consents in Maine was required by section
    2965(2)(A)—and that those consents were not, in fact, filed—she asserts that
    the failure to file the consents presents no impediment to the enforcement of
    the Maryland order in Maine. Her argument is that she substantially complied
    with UIFSA and, at most, the failure to file consents created a barrier of
    procedural dimension rather than jurisdictional, which George could—and
    did—waive by participating in the Maryland modification action without
    objection.
    [¶22] Subject matter jurisdiction “refers to the power of a particular
    court to hear the type of case that is then before it.” In re Child of Nicholas P.,
    
    2019 ME 152
    , ¶ 11,

    Brashear, 
    782 So. 2d 575
    , 577 (La. 2001) (“Jurisdiction . . . primarily indicates
    the power to adjudicate.”). In contrast, a court’s claim-processing rules, such as
    notice, pleading, and arbitration requirements, dictate how a court is to
    consider a case over which it has jurisdiction. Landmark Realty v. Leasure,
    
    2004 ME 85
    , ¶ 9,

    2009 ME 29
    , ¶ 20,
    15
    
    967 A.2d 690
    . Whereas claim-processing rules and lack of personal jurisdiction
    may be waived, lack of subject matter jurisdiction cannot be waived and may
    be raised at any time. M.R. Civ. P. 12(h)(1), (3); Hawley, 
    1999 ME 127

    511 A.2d 441
    , 443 (Me. 1986).
    [¶23]   To determine whether the consent requirement of UIFSA is
    jurisdictional or procedural, we interpret the statute de novo by evaluating its
    plain meaning to effectuate the Legislature’s intent. See Wuori v. Otis, 
    2020 ME 27
    , ¶ 6, 
    226 A.3d 771
    . We first interpret UIFSA’s “plain language by taking into
    account the subject matter and purposes of the statute, and the consequences
    of a particular interpretation.”

    58 A.3d 1083
     (“[S]tatutes
    must be read together and in light of the entire statutory scheme to produce
    cohesive results.”). If the plain language is ambiguous, we will then consider

    .
    [¶24] The UIFSA provisions at issue allow courts and litigants to identify
    which single court has “continuing, exclusive jurisdiction” to modify a child
    support order. 19-A M.R.S. §§ 2965(1), (2), 3253(1)(B), 3255(1); accord Md.
    16
    Code Ann., Family Law §§ 10-308(a), (b), 10-350(a)(2), 10-352(a). Patricia’s
    interpretation of these provisions would have us conclude that the Legislature
    simply did not mean “jurisdiction” when it used the word “jurisdiction” time
    and time again. See Wuori, 
    2020 ME 27
    , ¶ 10, 
    226 A.3d 771
     (affording a
    statutory term its “commonly understood” meaning); Jade Realty Corp. v. Town
    of Eliot, 
    2008 ME 80
    , ¶ 8, 
    946 A.2d 408
     (stating that a statute “may not be
    interpreted in such a way to read a provision out of existence or to render it
    surplusage”). Patricia’s interpretation would also wreak havoc on the word
    “exclusive,” which is defined as “[n]ot accompanied by others; single or sole”;
    “[n]ot divided or shared with others”; and “[n]ot allowing something else.”

    Servs. v. Monty,

    , ¶ 6, 
    704 A.2d 401
     (relying on the dictionary
    definition of statutory language in interpreting a child support provision). By
    its very nature, the continuing, exclusive jurisdiction for which UIFSA expressly
    provides places jurisdiction to modify in only one court at a time, thereby
    necessarily precluding the same exercise of jurisdiction by any other court.
    [¶25] Indeed, it is for just this reason that UIFSA also contains a guide to
    determining which order is “the controlling order” when more than one child
    support order has been issued:
    17
    1. Recognition of orders; one tribunal. If a proceeding is
    brought under this chapter and only one tribunal has issued a child
    support order, the order of that tribunal controls and must be so
    recognized.
    2. Recognition of orders; 2 or more tribunals. If a
    proceeding is brought under this chapter and 2 or more child
    support orders have been issued by tribunals of this State or
    another state or a foreign country with regard to the same obligor
    and same child, a tribunal of this State having personal jurisdiction
    over both the obligor and individual obligee shall apply the
    following rules and by order shall determine which order controls
    and must be recognized.
    A. If only one of the tribunals has continuing, exclusive
    jurisdiction under this chapter, the order of that tribunal
    controls.
    B. If more than one of the tribunals has continuing, exclusive
    jurisdiction under this chapter:
    (1) An order issued by a tribunal in the current home
    state of the child controls; or
    (2) If an order has not been issued in the current home
    state of the child, the order most recently issued
    controls.
    C. If none of the tribunals have continuing, exclusive
    jurisdiction under this chapter, the tribunal of this State shall
    issue a child support order, which controls.
    19-A M.R.S. § 2967(1)-(2); accord 
    Md. Code Ann., Family Law § 10-310
    (a)-(b)
    (LEXIS through June 1, 2021, of the 2021 Reg. Sess. of the Gen. Assembly). As
    the state in which the child support order was initially issued and the state
    18
    where the obligor continues to reside, and in the absence of consents to another
    state’s exercise of jurisdiction, Maine’s 2002 order remained the controlling
    order pursuant to sections 2965(1)(A) and 2967.
    [¶26]    Moreover, when the Legislature has intended for a UIFSA
    requirement to be procedural rather than jurisdictional, it has expressly said
    so. Title 19-A M.R.S. § 3256 requires a party who has obtained a modified child
    support order in another state to file a certified copy of that order with the
    Maine court that previously had continuing, exclusive jurisdiction in the
    matter.7     It also states, however, that the failure to file such notice is
    sanctionable but “does not affect the validity or enforceability of the modified
    order of the new tribunal having continuing, exclusive jurisdiction.” 19-A M.R.S.
    § 3256. In short, if the consent requirement of section 2965 were intended to
    be merely procedural, rather than jurisdictional, the Legislature could have
    stated so expressly, as it did with regard to the notice requirement of section
    3256. See HL 1, LLC v. Riverwalk, LLC, 
    2011 ME 29
    , ¶ 25, 
    15 A.3d 725
     (“It is
    apparent that the Legislature knew how to create statutory language that
    allows [the intended result in other provisions] . . . . Consequently, the absence
    The record suggests that Patricia did not file a copy of the Maryland modified order in Maine,
    7
    contrary to 19-A M.R.S. § 3256 (2021).
    19
    of such language [in this provision] demonstrates the Legislature’s intent [to
    provide for a different result].”); Anthem Health Plans of Me., Inc. v.
    Superintendent of Ins., 
    2012 ME 21
    , ¶ 17, 
    40 A.3d 380
    . Section 2965 dictates
    not how to approach child support modification cases (considerations
    addressed to claim-processing rules), but whether any of the courts of a given
    state may address a child support modification case at all—that is, subject
    matter jurisdiction. See In re Child of Nicholas P., 
    2019 ME 152
    , ¶ 11, 
    218 A.3d 247
    .
    [¶27] We therefore interpret the unambiguous plain language of UIFSA
    to state that the consent requirement set out in sections 2965(2)(A) and
    3253(1)(B) is jurisdictional rather procedural, as the District Court concluded.
    To interpret UIFSA as Patricia suggests would violate both the letter and spirit
    of UIFSA. Section 2965(1) contains the default provision that Maine has
    “continuing, exclusive jurisdiction” to modify its own child support orders.
    Sections 2965(2)(A), 3253(1), and 3255(1) then set out the narrow
    circumstances in which Maine no longer has “continuing, exclusive jurisdiction”
    to modify its own orders.     There is no dispute that none of these three
    circumstances was satisfied in this matter: George remained a resident of
    Maine, which precluded the Maryland court’s exercise of jurisdiction pursuant
    20
    to 
    Md. Code Ann., Family Law §§ 10-350
    (a)(1) or 10-352(a), see 19-A M.R.S.
    §§ 3253(1)(A), 3255(1), and no consents were filed on the record in Maine to
    Maryland’s exercise of jurisdiction pursuant to section 2965(2)(A),8
    see 
    Md. Code Ann., Family Law § 10-350
    (a)(2); Penkul v. Matarazzo, 
    2009 ME 113
    , ¶ 14, 
    983 A.2d 375
     (“The Massachusetts Probate and Family Court [as the
    issuing court] still has continuing, exclusive jurisdiction over the matter
    because the parties have not consented to another forum.”).
    [¶28] Because the plain language is unambiguous, we need not consider
    other indications of the Legislature’s intent in enacting UIFSA, see Wuori,
    
    2020 ME 27
    , ¶¶ 6-7, 
    226 A.3d 771
    , but we are not unaware of the abundant
    other authorities—in the official commentary to the uniform statute as
    promulgated by the NCCUSL, in the interpretations of the courts of a vast
    majority of other jurisdictions, and in the legislative history of Maine’s UIFSA
    enactment itself—that confirm identical language to set out the jurisdictional
    limits on child support modifications.9 Aside from the persuasiveness of these
    Patricia’s additional suggestion—that Maryland obtained jurisdiction because she and George
    8
    consented to it in the Maryland court’s record—is untenable given the statute’s language requiring
    the parties to “file consent in a record with the tribunal of this State” as the issuing state. 19-A M.R.S.
    § 2965(2)(A) (2021).

    authorities in their own right, Maine’s UIFSA specifically encourages us to
    interpret the statute consistent with these other jurisdictions: “In applying and

    uniformity of the law with respect to its subject matter among states that enact
    it.” 19-A M.R.S. § 3401; see HL 1, LLC,

    omitted).
    [¶29] The intent of UIFSA, in Maine and across the country, is to promote
    uniformity in child support through the one-order system, by which
    enforcement is broadly available and modification is narrowly circumscribed.

    another state was sufficient to divest the issuing court of its continuing, exclusive jurisdiction would

    in the issuing court superfluous”); Chalmers v. Burrough,

    child support, . . . the district courts’ jurisdiction over child support proceedings was modified when
    Utah passed the Uniform Interstate Family Support Act” (quotation marks omitted)).
    22
    part, through the detailed provisions setting out which single state enjoys
    continuing, exclusive jurisdiction in a host of different circumstances. 
    Id.
     That
    intent is compromised—and the cornerstone provisions of UIFSA thereby
    rendered impotent—by allowing multiple states to fashion child support
    orders regarding the same family at the same time, the exact problem UIFSA
    was intended to fix.10 See Cohen, 25 N.E.3d at 848 (declining to “upset a
    carefully constructed uniform set of laws adopted in all fifty States”).
    We are not persuaded by Patricia’s contention that her “substantial compliance” with UIFSA is
    10
    sufficient to allow for the registration and enforcement of the Maryland order in Maine or that, in any
    event, George may no longer collaterally attack the Maryland order on this basis because he did not
    challenge the Maryland court’s jurisdiction before the Maryland court. Substantial compliance is
    allowed in other contexts, if at all, for harmless, technical oversights, often in relation to notice
    requirements, see, e.g., Erickson v. State, 
    444 A.2d 345
    , 350 (Me. 1982), but substantial compliance
    cannot convey subject matter jurisdiction pursuant to UIFSA where it otherwise does not exist.
    Nor is George precluded from collaterally attacking the Maryland order on the basis of jurisdiction
    because he did not make that same argument to the Maryland court, to whose jurisdiction he
    submitted. By participating in the Maryland proceedings, George waived his right to challenge its
    personal jurisdiction, not its subject matter jurisdiction. See Fore, LLC v. Benoit, 
    2012 ME 1
    , ¶ 5,
    
    34 A.3d 1125
     (“The term ‘personal jurisdiction’ refers to a court’s power to bring a person into its
    adjudicative process.” (alteration omitted) (quotation marks omitted)); Penkul v. Matarazzo,
    
    2009 ME 113
    , ¶ 8, 
    983 A.2d 375
     (characterizing the lack of personal jurisdiction as a “procedural
    defect”); supra ¶ 22. In contrast, a judgment issued without subject matter jurisdiction is void, and
    thus, subject matter jurisdiction may be raised at any time, including sua sponte by the court. Hawley
    v. Murphy, 
    1999 ME 127
    , ¶ 8, 
    736 A.2d 268
    . “A challenge to a court’s subject matter jurisdiction is
    one instance where a collateral attack on a judgment is permissible, because fundamental lack of
    authority in the court to enter the judgment for want of jurisdiction either of the subject matter or
    over the parties transcends any waiver of the right of appeal.” Faith Temple v. DiPietro, 
    2015 ME 166
    ,
    ¶ 21, 
    130 A.3d 368
     (alterations omitted) (quotation marks omitted).
    Indeed, consideration of the subject matter jurisdiction of a prior court is not only approved at
    common law, it is expressly required by UIFSA. See 19-A M.R.S. § 3152(3) (2021) (instructing Maine
    courts to evaluate the jurisdiction underlying another state’s entry of a child support order: “Except
    as otherwise provided in this chapter, a tribunal of this State shall recognize and enforce, but may
    not modify, a registered support order if the issuing tribunal had jurisdiction.” (emphasis added));
    19-A M.R.S. § 2967(2) (2021) (providing the means to determine which child support order is
    “controlling” in the face of multiple orders); Cohen, 25 N.E.3d at 847-48; Hawley, 
    1999 ME 127
    ,
    23
    [¶30] Patricia and George’s failure to file consents pursuant to section
    2965(2)(A) deprived the Maryland court of subject matter jurisdiction to
    modify Maine’s 2002 child support order, the order Maryland issued was
    therefore void ab initio, and the Maine District Court correctly declined to
    register the Maryland order for enforcement in Maine on that basis.
    The entry is:
    Judgment affirmed.

    orders only if the issuing court had jurisdiction to issue the order” and stating that “Maine courts . . .
    do not have the authority to enforce a divorce order issued in another state by a court lacking subject
    matter jurisdiction to issue the order”).
    Our decision today is also consistent with our prior determinations that a judgment may be
    subject to collateral attack for lack of subject matter jurisdiction when “there is ‘manifest abuse of
    authority, substantial infringement of the authority of another tribunal, or a need to entertain a
    belated challenge as a matter of procedural fairness.’” State v. Thompson,

    see Restatement (Second) of Judgments § 12 (Am. Law Inst. 1982). Allowing registration and
