    ORDER
    ¶1     Held: The trial court erred in finding that the mother’s claim for child support arrearage
    was barred by laches and equitable estoppel; we also find the court abused its
    discretion when it determined that the additional income the father earned from
    working at a healthcare facility could not be considered in calculating his child
    support obligation. Conversely, we find the court properly: calculated the downward
    modification of the father’s child support obligation; made the modification of child
    support retroactive to June 2020, rather than February 2020; determined that the
    parties did not have an agreement to equally share their daughter’s college costs;
    allocated the parties’ respective contributions toward the college expenses; and
    denied the father’s petition for attorney fees.
    No. 1-21-1187
    ¶2        Petitioner Lynn P. Christos (Lynn) appeals, and respondent Steve C. Christos (Steve)
    cross-appeals, from a post-decree order entered by the circuit court of Cook County. For the
    reasons that follow, we affirm in part, reverse in part, and remand for further proceedings. 1
    ¶3                                         I. BACKGROUND
    ¶4        Lynn and Steve were married on December 9, 2000. Two children were born during the
    marriage, Christina on May 1, 2002, and Peter on September 22, 2003. A judgment for dissolution
    of marriage was entered on February 6, 2006, dissolving the parties’ marriage. Incorporated into
    the judgment was the parties’ marital settlement agreement (MSA) and joint parenting agreement
    (JPA). The JPA provided that the parties would have joint custody of the children, with Lynn
    having their primary residential custody.
    ¶5        The court also issued a uniform order for support setting forth Steve’s child support
    obligations under the MSA. Paragraph five of the MSA provided that based on Steve’s annual
    income of $241,654 as a medical doctor, he was to pay $3,688 per month in child support. In
    addition, Steve was required to pay 28% of any net income he received from additional
    employment (moonlighting) within seven days of receipt. “Net income” was defined as income
    Steve received from “moonlighting,” less any deductions as set forth in section 505(a)(3) of the
    Illinois Marriage and Dissolution of Marriage Act (Dissolution Act) (750 ILCS 5/505(a)(3) (West
    2000)).
    ¶6        The MSA also included a provision regarding the parties’ obligations to contribute toward
    their children’s college expenses. Paragraph nine of the MSA provided that each party would
    contribute to their children’s college expenses “commensurate with his/her respective ability to do
    1

    appeal has been resolved without oral argument upon entry of a separate written order.
    2
    No. 1-21-1187
    so at the time each child is ready to attend college.”
    ¶7      On January 29, 2020, Steve filed a motion to modify child support and for contribution
    toward college expenses. The motion was based on Steve’s claim of substantial change in
    circumstances, namely that Christina had been exclusively residing with him since August 2014.
    Steve’s request for contribution for college expenses was based on his contention that the parties
    agreed to allocate those costs equally between them, after application of any scholarships Christina
    received.
    ¶8      Lynn responded by filing a petition for rule to show cause, seeking to hold Steve in indirect
    civil contempt of court. 2 In the petition, Lynn alleged that Steve violated the MSA by failing to
    provide her with copies of his federal income tax returns for 2006, “or for any year thereafter.”
    Lynn based her allegation on paragraph five of the MSA which contained a handwritten notation
    stating that “[t]he parties will exchange copies of their filed Federal income tax returns no later
    than April 21st of each year (or as soon as filed if thereafter) until their obligations under this
    agreement are satisfied.” Lynn maintained that she required Steve’s federal income tax returns to
    determine if he was earning any income in addition to the annual income he represented he was
    earning in the MSA. Lynn subsequently issued a subpoena to Steve’s accountant requesting
    production of Steve’s federal income tax returns for the years 2006 through 2017.
    ¶9      Lynn asserted that before the trial court ruled on Steve’s motion to modify child support,
    the court should order Steve to tender the federal income tax returns she requested. Lynn further
    asserted that any contributions she was required to pay toward Christina’s college expenses should
    be based on “in state college education expenses which the child were to incur if she were to attend
    2
    “[T]he purpose of a rule to show cause petition is to determine if a party has complied with a prior
    court order, allows the allegedly noncompliant party the opportunity to explain any noncompliance and, if
    necessary, allows the trial court to enforce the prior court order.” In re Marriage of Britton, 
    2022 IL App (5th) 210065
    , ¶ 42.
    3

    the University of Illinois at Urbana-Champaign.”
    ¶ 10   Lynn also filed a petition for interim and prospective attorney fees, claiming to have
    insufficient funds to pay for an attorney. Lynn averred that she borrowed funds from her father to
    cover her legal expenses. Lynn alleged that Steve had the financial ability to contribute to her
    attorney fees, as well as pay his own attorney fees.
    ¶ 11   In response, Steve argued that Lynn’s petition for rule to show cause was premature as
    there was no trial court finding that he had violated the MSA by failing to provide Lynn with
    copies of his federal income tax returns. Steve maintained that the provision in the MSA regarding
    the obligation to turn over federal income tax returns was mutual. Steve claimed that he provided
    Lynn with copies of his federal income tax returns for the years 2006 through 2010. He argued
    that Lynn was the one who breached the MSA by only providing him with copies of her federal
    income tax returns for the years 2006 through 2008, and he maintained that she had done so only
    to claim Christina as a dependent exemption. Steve moved to quash the subpoena for his 2006 -
    2017 tax returns.
    ¶ 12   Steve contended that Lynn requested copies of his federal income tax returns only after he
    filed his motion to modify child support. Steve argued that Lynn’s request for his tax returns should
    be denied on the basis of one or more of the following affirmative defenses: (a) breach of contract;
    (b) waiver; (c) estoppel; (d) laches; or (e) unclean hands.
    ¶ 13   Steve added that the subpoena should be quashed on the grounds that it was overbroad and
    sought information unrelated to issues pending before the trial court. Steve further claimed that, in
    ruling on Lynn’s petition for interim and prospective attorney fees, the trial court must consider
    the parties’ current incomes and assets, and the amounts paid to their respective attorneys.
    ¶ 14   On May 8, 2020, the trial court ordered Steve to produce his tax returns for 2006 through
    4
    No. 1-21-1187
    2019. On May 28, 2020, following a hearing, the court entered an order denying Lynn’s petition
    for rule to show cause. The court found that: (1) Lynn “shall issue an Amended Request to Produce
    regarding [Steve’s] tax returns on or before May 29, 2020”; (2) Steve “shall provide responses
    and/or objections to the Amended Request to Produce on or before June 12, 2020. If [Steve]
    produces documents containing redactions, he shall also provide a corresponding privilege log
    regarding those redactions with the production”; and (3) Steve “is granted leave to file an Amended
    Motion for Protective Order in connection with the production of his tax returns.” The court also
    quashed the subpoena that was served on Steve’s accountant.
    ¶ 15   Lynn filed a second petition for rule to show cause on June 12, 2020, which she later
    amended on September 10, 2020. Lynn alleged that Steve violated the child support provision of
    the MSA by failing to pay her “28% of his net income in excess of the amount of $241,654 on an
    annual basis.” Lynn claimed Steve owed child-support arrearage for 2008, and 2016 through 2019.
    ¶ 16   On June 16, 2020, Lynn filed an emergency petition for a temporary restraining order and
    preliminary injunction seeking to enjoin and prohibit Steve from discussing their pending litigation
    with their daughter Christina. According to Lynn, Christina had become verbally abusive toward
    her after discussing the pending litigation with Steve. Lynn claimed that the verbal abuse included
    references to her counsel and his daughter. Lynn noted that Christina and her counsel’s daughter
    recently graduated together from the same high school. Lynn contended that, in light of Christina’s
    verbal abuse, her counsel had become concerned about his and his daughter’s safety with regard
    to Christina.
    ¶ 17   Steve countered that it was Lynn who had discussed the pending litigation with Christina
    and added that his ex-wife and daughter had not had a civil relationship since Christina moved in
    with him in August 2014. Steve contended that Lynn’s emergency petition was rife with hearsay,
    5
    No. 1-21-1187
    was not well grounded in fact or existing law, and lacked any good-faith arguments. He claimed
    that the emergency petition was filed to harass and cast him in a negative light. Steve moved to
    disqualify Lynn’s counsel on the ground that counsel’s status as a witness to Lynn’s emergency
    petition barred counsel from serving as Lynn’s attorney.
    ¶ 18   Lynn subsequently withdrew her emergency petition prior to a hearing on the merits and
    she retained new counsel. Steve was granted leave to file a motion for sanctions pursuant to Illinois
    Supreme Court Rule 137 (eff. Jan. 1, 2018). On July 29, 2020, the trial court granted Steve’s
    motion for sanctions and gave him leave to file a fee petition relating to the motion. In addition,
    the court denied Lynn’s petition for interim and prospective attorney fees, without prejudice.
    Thereafter, Steve filed a fee petition and an amended motion to modify child support and for
    contribution toward college expenses.
    ¶ 19   On February 19, 2021, the trial court commenced a seven-day bench trial on the parties’
    respective post-decree claims. At the close of the evidence, the parties submitted written closing
    arguments, and proposed findings of fact and conclusions of law. The trial court took the case
    under advisement, and on August 30, 2021, issued a detailed written order.
    ¶ 20   In its order, the trial court made certain findings of fact and conclusions of law relevant to
    the issues on appeal. The court found that a substantial change in circumstances occurred in August
    2014, when Christina began exclusively residing with Steve and he became her sole caretaker. The
    court noted that after Christina moved in with Steve, he continued to pay Lynn monthly child
    support in accordance with the terms of the MSA, without any financial contributions from Lynn.
    The court also noted that Steve continued to have nearly 50% parenting time with Peter.
    ¶ 21   The trial court determined that this de facto change in custody entitled Steve to a
    modification of child support. The court modified Steve’s child support obligation from $3,688
    6
    No. 1-21-1187
    per month to $1,865 per month. The order made this modification retroactive from June 1, 2020.
    The court determined that Steve was entitled to a credit of $7,783 for overpaid child support.
    ¶ 22   The trial court found that based on these facts, Lynn’s claim for child support arrearage
    was barred by the doctrine of equitable estoppel. In addition, the court determined that Lynn’s 14-
    year delay in seeking to collect purported child support arrearage was unreasonable and prejudicial
    to Steve. As a result, the court held that Lynn’s claim for arrearage was also barred by the equitable
    doctrine of laches.
    ¶ 23   In regard to Steve’s amended motion to modify, which requested contribution toward
    college expenses, the trial court found that the parties had not reached “an agreement to equally
    divide the costs of Christina’s attendance at college.” The court determined that Steve had a
    substantially greater ability to contribute to Christina’s college costs than Lynn. The court
    retroactively allocated 80% of the college expenses to Steve and 20% to Lynn.
    ¶ 24   The trial court denied Steve’s petition for attorney fees and denied Lynn’s amended second
    petition for rule to show cause. However, the court found that based upon its interpretation of
    paragraph five of the parties’ MSA, Steve had certain “moonlighting” income from which he owed
    Lynn child support. At the same time, though, the court found that Steve’s failure to pay the
    amounts due for additional child support was not willful because he “presented compelling cause
    and justification for his failure to make the payments.” Thus, the court held that Steve was not in
    indirect civil contempt.
    ¶ 25   The trial court found that Steve owed Lynn $8,264 in support arrears for years 2006 through
    2020, plus interest. The court determined that this amount was offset by the credit Steve received
    for his overpayment of child support.
    ¶ 26   Lynn has appealed from these rulings and Steve has cross-appealed. We first address the
    7
    No. 1-21-1187
    arguments raised by Lynn in her appeal.
    ¶ 27                                      II. ANALYSIS
    ¶ 28                                     A. Lynn’s Appeal
    ¶ 29      Lynn argues the trial court erred in finding that her claim for child support arrearage was
    barred by laches and equitable estoppel. She also argues that the court improperly construed the
    meaning of the term “moonlighting” as set forth in the decree. We address each argument in turn.
    ¶ 30                              1. Laches and Equitable Estoppel
    ¶ 31      The trial court held that Lynn’s 14-year delay in seeking to collect child support arrearage
    was unreasonable. The court determined that Steve was prejudiced by the delay because he
    continued to pay child support even though he was entitled to petition the court to modify his
    support obligations after Christina moved in with him. Based on this, the court applied laches to
    bar Lynn’s claim for child support arrearage for the time Christina resided with Steve. Lynn
    contends this was error.
    ¶ 32      Laches is an equitable affirmative defense that bars recovery by a litigant whose
    unreasonable delay in bringing an action prejudices the opposing party. BankUnited, National
    Ass’n v. Giusti, 
    2020 IL App (2d) 190522
    , ¶ 39; In re Marriage of Davenport, 
    388 Ill. App. 3d 988
    , 993 (2009). The party asserting a laches defense must show, by a preponderance of the
    evidence, that: (1) the plaintiff failed to exercise due diligence in bringing the action and (2) they
    suffered prejudice as a result of the delay. Kampmann v. Hillsboro Community School District No.
    3 Board of Education, 
    2019 IL App (5th) 180043
    , ¶¶ 14-15. The doctrine of laches is “grounded
    in the equitable notion that courts are reluctant to come to the aid of a party who has knowingly
    slept on his rights to the detriment of the opposing party.” Tully v. State, 
    143 Ill. 2d 425
    , 432
    (1991).
    8
    No. 1-21-1187
    ¶ 33   “Whether laches is available as a defense is determined by the facts and circumstances of
    each case.” Kampmann, 
    2019 IL App (5th) 180043
    , ¶ 14. The determination as to whether laches
    applies to bar a claim is generally left to the sound discretion of the trial court, whose decision will
    not be disturbed absent an abuse of that discretion. Richter v. Prairie Farms Dairy, Inc., 
    2016 IL 119518
    , ¶ 51. Lynn contends, however, that de novo review is appropriate since the trial court
    misapplied the law when it determined that laches applied to bar her claim for child support
    arrearage.
    ¶ 34   We agree that de novo review is appropriate. Whether the trial court misapplied Illinois
    law requires us to interpret statutory language. Statutory interpretation presents a question of law
    subject to de novo review. In re Andrew B., 
    237 Ill. 2d 340
    , 348 (2010).
    ¶ 35   Lynn contends that, as a matter of law, laches does not apply to bar her claim for child
    support arrearage. Lynn relies on language in section 12-108(a) of the Code of Civil Procedure
    (Code), as amended in 1997, which provides that “[c]hild support judgments, including those
    arising by operation of law, may be enforced at any time.” 735 ILCS 12-108(a) (West 2004). 3
    Lynn maintains that this statutory language precludes the application of laches as a defense against
    the enforcement of her claim for child support arrearage.
    ¶ 36   In construing section 12-108(a) of the Code, our primary objective is to ascertain and give
    effect to the intent of the legislature. In re Craig H., 
    2022 IL 126256
    , ¶ 25. The most reliable
    indicator of that intent is the statutory language itself, which must be given its plain and ordinary
    meaning. Evanston Insurance Co. v. Riseborough, 
    2014 IL 114271
    , ¶ 15. “When the statutory
    3
    Prior to July 1, 1997, the statute of limitations governing the enforcement of child support
    judgments required that an action be brought within 20 years of the judgment. See In re Marriage of
    Davenport, 
    388 Ill. App. 3d 988
    , 992 (2009) (citing 735 ILCS 5/13-218 (West 1996)). On July 1, 1997, the
    legislature enacted Public Act 90-18, which amended the statute of limitations to provide that “[c]hild
    support judgments, including those arising by operation of law, may be enforced at any time.” 
    Id.
    9
    No. 1-21-1187
    language is clear and unambiguous, it must be construed as written, without reading in exceptions,
    conditions, or limitations not expressed by the legislature.” In re Craig H., 
    2022 IL 126256
    , ¶ 25.
    ¶ 37    In In re Marriage of Saputo, 
    363 Ill. App. 3d 1011
     (2006), this court held that the 1997
    amendment to section 12-108(a), which added the phrase “may be enforced at any time,” allowed
    for child support judgments to be enforced at any time, even after expiration of the applicable
    statute of limitations. 
    Id. at 1013-16
    .
    ¶ 38    Saputo concerned a statute of limitations defense rather than a laches defense. In general,
    “[s]tatutes of limitations, applicable in legal actions, are not directly controlling in suits seeking
    equitable relief.” Meyers v. Kissner, 
    149 Ill. 2d 1
    , 12 (1992). “Statutes of limitations apply to
    actions at law, while laches is the doctrine of limitations applied to actions in equity.” 54 C.J.S.
    Limitations of Actions § 5 (2005). However, “a statute of limitations may serve as a guide in
    determining whether an action is barred by laches.” 13 Am. Jur. 2d Cancellation of Instruments §
    40 (2023) (citing Diehl v. Olson, 
    141 Ill. App. 3d 110
    , 115 (1986)). “When fixing the period in
    which rights and claims would be barred by laches, equity follows the law, and courts of equity
    adopt the period of limitations fixed by statute.” In re Marriage of Smith, 
    347 Ill. App. 3d 395
    ,
    401 (2004). Consequently, in cases such as this, where a claim or right is not barred by the statute
    of limitations, laches is available as a defense where special circumstances exist that would make
    it inequitable to grant the requested relief. See In re Marriage of Smith, 347 Ill. App. 3d at 401;
    Cannella v. Village of Bridgeview, 
    284 Ill. App. 3d 1065
    , 1071 (1996).
    ¶ 39    Steve contends there are special circumstances which support the application of laches to
    bar Lynn’s claim for child support arrearage. In support of this contention, Steve relies on the same
    reasoning the trial court relied upon—namely that Steve was prejudiced by Lynn’s delay in seeking
    to collect child support arrearage because he continued to pay child support, even though he was
    10
    No. 1-21-1187
    entitled to petition the court to modify the support after Christina moved in with him. Steve seems
    to suggest that Lynn’s conduct in continuing to accept child support payments from him, without
    objection or complaint, lulled him into not filing a motion to modify. We find that such a
    suggestion unfairly penalizes Lynn for Steve’s inaction in failing to petition the court to modify
    his child support obligations. Steve’s failure in this regard was a result of his own doing and cannot
    be attributed to Lynn. Steve cannot now complain that he was prejudiced by his own decision not
    to file a motion to modify child support. Indeed, it appears that Steve is the party who failed to
    exercise due diligence.
    ¶ 40   Steve has failed to show any prejudice to his ability to petition the trial court to modify his
    child support obligations. Therefore, we find the trial court erred in finding that laches barred
    Lynn’s claim for child support arrearage where Steve suffered no prejudice as a result of Lynn’s
    delay in seeking to collect the arrearage. “Mere delay in bringing suit is not enough to establish
    laches; the defendant must show prejudice or hardship from the delay.” Gacki v. Bartels, 
    369 Ill. App. 3d 284
    , 293 (2006). Here, there was no prejudice from the delay.
    ¶ 41   For these same reasons, we also hold that the trial court erred in finding that Lynn’s claim
    for child support arrearage was barred by equitable estoppel. Like laches, equitable estoppel
    requires a showing of prejudice. See, e.g., Northwest Diversified, Inc. v. Desai, 
    353 Ill. App. 3d 378
    , 399 (2004) (noting that prejudice is an essential element of equitable estoppel).
    ¶ 42                        2. Construction of the Word “Moonlighting”
    ¶ 43   Paragraph five of the MSA obligated Steve to pay Lynn 28% of any net income he received
    from additional employment (“moonlighting”) within seven days of receiving it. The trial court
    found that the language in this paragraph was ambiguous on the ground that it was susceptible to
    more than one interpretation. In an effort to resolve this purported ambiguity, the court determined
    11
    No. 1-21-1187
    that “moonlighting” meant “additional employment,” which in turn meant “working for another
    employer as an employee and/or as an officer of another entity.” Based on this construction, the
    court held that the additional income Steve earned from working at Resurrection Healthcare did
    not constitute “moonlighting” income because it was not derived from “additional employment.”
    The court determined that the additional income could not be considered in calculating Steve’s
    child support obligation. “A trial court’s determination of income is reviewed under an abuse of
    discretion standard.” In re Marriage of Britton, 
    2022 IL App (5th) 210065
    , ¶ 57; In re Marriage
    Sinha, 
    2021 IL App (2d) 191129
    , ¶ 43 (same).
    ¶ 44      Black’s Law Dictionary defines “moonlighting” as: “The fact or practice of working at a
    second job after the hours of a regular job. – Also termed dual employment; multiple job-holding.”
    Black’s Law Dictionary 1161 (10th ed. 2014) (italics in original). This definition is largely
    consistent with the definition adopted by the trial court. Therefore, we find no error in the court’s
    definition of “moonlighting.”
    ¶ 45      However, we disagree with the trial court’s finding that because the additional income
    Steve received from Resurrection Healthcare did not constitute “moonlighting” income, that it was
    not subject to a claim for child support arrearage. The statute makes no distinction between income
    derived from moonlighting employment, additional employment, or primary employment. “For
    purposes of determining statutory child support obligations, the General Assembly has adopted an
    expansive definition of what constitutes” income. In re Marriage of Rogers, 
    213 Ill. 2d 129
    , 136
    (2004).
    ¶ 46      Our supreme court has explained that for purposes of child support, income is “simply
    ‘something that comes in as an increment or addition *** : a gain or recurrent benefit that is
    usu[ally] measured in money *** : the value of goods and services received by an individual in a
    12
    No. 1-21-1187
    given period of time. ’ ” In re Marriage of Rogers, 
    213 Ill. 2d at 136-37
     (2004) (quoting Webster’s
    Third New International Dictionary 1143 (1986)). Income for purposes of calculating child support
    has been defined as “any form of payment to an individual, regardless of its source and regardless
    of whether it is nonrecurring, since ‘the relevant focus under section 505 is the parent’s economic
    situation at the time the child support calculations are made by the circuit court.’ ” In re Marriage
    of Dahm-Schell, 
    2021 IL 126802
    , ¶ 40 (quoting In re Marriage of Rogers, 
    213 Ill. 2d at 138
    ). The
    statutory definition of income is broad and “includes gains and benefits that enhance a
    noncustodial parent’s wealth and facilitate that parent’s ability to support a child or children.” In
    re Marriage of Mayfield, 
    2013 IL 114655
    , ¶ 16. The Marriage Act “creates a rebuttable
    presumption that any such gain or benefit is income for child support unless specifically excluded
    by the statute.” In re Marriage of Dahm-Schell, 
    2021 IL 126802
    , ¶ 41.
    ¶ 47   Based on these definitions of income and considering the principles which must guide the
    trial court in calculating child support, we hold that the court abused its discretion when it
    determined that the additional income Steve earned from working at Resurrection Healthcare could
    not be considered in calculating his child support obligation.
    ¶ 48   Lynn argues that if we reject Steve’s definition of “moonlighting,” this necessitates a
    reconsideration of the trial court’s finding that he was not guilty of indirect civil contempt for
    failing to provide her with copies of his federal tax returns. Lynn contends that the court
    determined that Steve was in compliance with the child support order based on its interpretation
    of the term “moonlighting.” Lynn suggests that “a different definition adopted on appeal would
    render Steve in noncompliance.”
    ¶ 49   Lynn’s arguments are an invitation to this court to relitigate the issue of Steve’s tax returns
    and substitute our judgment for that of the trial court. It is an invitation we decline to accept. Our
    13
    No. 1-21-1187
    finding does not disturb the trial court’s determination the Steve acted reasonably, in part, due to
    the ambiguity of the word “moonlighting.”

    ¶ 51                         1. Retroactive Modification of Child Support
    ¶ 52   The trial court determined that the de facto change in custody, which occurred in August
    2014, when Christina began exclusively residing with Steve, entitled Steve to a downward
    modification of child support. The court reduced Steve’s child support from $3,688 per month to
    $1,865 per month. The court made this modification retroactive from June 1, 2020 through July
    31, 2021.
    ¶ 53   In general, a trial court’s decision regarding the retroactivity of child support is reviewed
    for an abuse of discretion. In re Marriage of Schlei, 
    2015 IL App (3d) 140592
    , ¶ 12. An abuse of
    discretion occurs when the court’s ruling is arbitrary, fanciful, or unreasonable, or when the ruling
    rests on an error of law. Urban Partnership Bank v. Chicago Title Land Trust Co., 
    2017 IL App (1st) 162086
    , ¶ 15.
    ¶ 54   Steve contends that the trial court abused its discretion by applying an incorrect section of
    the Dissolution Act to calculate the downward modification of his child support obligation. Steve
    argues that the court should have relied on section 505(a)(3.8) of the Dissolution Act, rather than
    section 505(a)(2), in making the calculation. Section 505(a)(3.8) gives guidance in cases where
    physical care is shared between the parents and provides in relevant part that:
    “If each parent exercises 146 or more overnights per year with the child, the basic child
    support obligation is multiplied by 1.5 to calculate the shared care child support obligation.
    The court shall determine each parent’s share of the shared care child support obligation
    based on the parent’s percentage share of combined net income.” 750 ILCS 5/505(a)(3.8)
    14
    No. 1-21-1187
    (West 2018).
    ¶ 55    Steve claims that the parties’ JPA granted him at least 156 overnights, exclusive of holiday
    and vacation time. Steve maintains that his parenting time was increased in July 2007, when he
    was awarded parenting time with the children for one half of the summer, which he claims resulted
    in the parties having nearly equal parenting time. Steve points out that he had nearly 50% parenting
    time with Peter.
    ¶ 56    Steve contends that application of section 505(a)(3.8) to the income figures proposed by
    Lynn and adopted by the trial court, would have resulted in him owing $1,229 per month in child
    support rather than $1,865 per month. Lynn responds that the trial court properly exercised its
    discretion when, instead of relying on section 505(a)(3.8), it relied on the statutory factors
    enumerated in section 505(a)(2) (750 ILCS 5/505(a)(2) (West 2018)).
    ¶ 57    Section 505(a)(1) of the Dissolution Act establishes the statutory guidelines trial courts
    should consider in determining child support. In re Marriage of Mayfield, 
    2013 IL 114655
    , ¶ 17.
    The court computes the amount of child support to be paid by the supporting parent based on the
    number of children and a corresponding percentage of the supporting parent’s net income. Id. ¶¶
    16-17; In re Marriage of Turk, 
    2014 IL 116730
    , ¶ 17.
    ¶ 58    When custody is shared, the trial court has the discretion to choose between two options in
    determining child support: (1) apportion the percentage between the parents; or (2) consider the
    statutory factors enumerated in section 505(a)(2). 4 In re Marriage of Smith, 
    2012 IL App (2d) 110522
    , ¶ 66; In re Marriage of Reppen-Sonneson, 
    299 Ill. App. 3d 691
    , 695 (1998). Here, the
    4
    The statutory factors include, but are not limited to, the following: the financial resources and
    needs of the parents and child; the standard of living the child would have enjoyed had the marriage or civil
    union not been dissolved; and the physical and emotional condition of the child and the child’s educational
    needs. 750 ILCS 5/505(a)(2)(A)-(D) (West 2018).
    15
    No. 1-21-1187
    trial court chose the second option based on Steve’s greater income compared to Lynn’s income.
    The court found that Lynn’s imputed yearly income was $30,000, and that Steve’s yearly income
    was $331,802. “[W]hen one parent earns a disproportionately greater income than the other, that
    parent clearly should bear a larger share of the support.” In re Keon C., 
    344 Ill. App. 3d 1137
    ,
    1143 (2003). Based on the record before us, we cannot say that the court abused its discretion by
    choosing to apply section 505(a)(2), rather than section 505(a)(3.8).
    ¶ 59   Steve next contends the trial court erred by not making the downward modification of child
    support retroactive to February 2020—when Lynn received notice of the motion to modify. Lynn
    responds that it was Steve’s delay in producing his tax returns which justified the court’s decision
    to make the modification retroactive to June 2020, rather than February 2020.
    ¶ 60   The retroactive modification of child support is addressed in section 510(a) of the
    Dissolution Act (750 ILCS 5/510(a) (West 2014)). In re Marriage of Pratt, 
    2014 IL App (1st) 130465
    , ¶ 33. Section 510(a) “provides that the court may modify child support payments only as
    to installments accruing subsequent to due notice by the moving party of the filing of the motion
    for modification.” In re Marriage of Freesen, 
    275 Ill. App. 3d 97
    , 106 (1995) (citing section
    510(a)). The “due notice” requirement insures that the nonmoving party “is put on notice prior to
    any change being made with the respect to the original child support and expense obligations.” In
    re Marriage of Petersen, 
    2011 IL 110984
    , ¶ 18. Therefore, “the earliest point to which retroactive
    modification of *** support payments may be ordered is the date on which the non-moving party
    receives ‘due notice’ from the moving party of the filing of the modification petition.” In re
    Marriage of Hawking, 
    240 Ill. App. 3d 419
    , 426 (1992). However, a trial court’s decision whether
    to order a retroactive modification after the nonmoving party receives notice of the motion to
    modify, is a matter within the court’s discretion. See Brandt v. Brandt, 
    99 Ill. App. 3d 1089
    ,
    16
    No. 1-21-1187
    1108-09 (1981) (interpreting the predecessor to section 510(a), which allowed a modification to
    be retroactive to the date of the filing of the petition to modify). 5
    ¶ 61    Here, the record shows that in May 2020, the trial court ordered Steve to produce his tax
    returns for 2006 through 2019. In July 2020, the court ordered him to tender unredacted copies of
    his tax returns for 2011 through 2017. It subsequently took Steve a further six months to January
    2021, to agree to a protective order regarding the terms of the tender of his tax returns. We also
    note that in the same order the court made the downward modification of child support retroactive
    to June 1, 2020, the court found that Steve “lacked credibility” with respect to his income and tax
    filings. Under these circumstances, we cannot say that the court abused its discretion by making
    the modification retroactive to June 1, 2020.
    ¶ 62                                      2. Allocation of College Costs
    ¶ 63    Steve next claims the trial court erred in finding that he and Lynn did not have an agreement
    to equally share Christina’s college expenses. Steve alleges that he, Lynn, and Christina, met at a
    restaurant in January 2020, where they agreed that Christina would attend the University of Denver
    (DU). Steve maintains that he and Lynn agreed to equally share Christina’s college expenses at
    DU, which after accounting for the scholarships she received, amounted to each party being
    obligated to contribute $25,000.
    ¶ 64    Steve claims that the parties’ agreement was subsequently memorialized in an exchange of
    two January 2020 emails and was reflected by objective conduct. Steve contends that in reliance
    on Lynn’s agreement to equally share the college expenses, Christina committed to attending DU,
    and he paid a deposit for her housing at the university. According to Steve, after Lynn reneged on
    the agreement, Christina decided not to attend DU, and instead enrolled at Michigan State
    5
    “[W]hether a modification is to be retroactive to the date of the filing of the petition, or at any time
    after, is a matter within the trial court’s discretion.” Brandt v. Brandt, 
    99 Ill. App. 3d 1089
    , 1108-09 (1981).
    17
    No. 1-21-1187
    University (MSU). Steve argues on appeal that based on the parties’ agreement to equally share
    Christina’s college expenses at DU, they should equally share her college expenses at MSU.
    ¶ 65   The formation of a valid contract requires an offer, acceptance of the offer, consideration,
    and terms that are reasonably definite and certain. Vassell v. Presence Saint Frances Hospital,
    
    2018 IL App (1st) 163102
    , ¶ 51. To form a valid contract, “there must be mutual assent by the
    contracting parties on the essential terms and conditions of the subject about which they are
    contracting.” Reese v. Forsythe Mergers Group, Inc., 
    288 Ill. App. 3d 972
    , 979 (1997). “[T]he
    issues of whether a contract existed, the parties’ intent in forming it, and its terms are all questions
    of fact to be determined by the trier of fact.” Prignano v. Prignano, 
    405 Ill. App. 3d 801
    , 810
    (2010). We give deference to the trial court’s findings of fact, which we disturb only if they are
    against the manifest weight of the evidence. 
    Id.
     A factual finding is against the manifest weight of
    the evidence only when the opposite conclusion is apparent, or when the finding is arbitrary,
    unreasonable, or not based on the evidence. Country Mutual Insurance Co. v. Olsak, 
    2022 IL App (1st) 200695
    , ¶ 109.
    ¶ 66   Some Illinois courts, and courts in other jurisdictions, have recognized that an exchange of
    emails may constitute an enforceable agreement if the writings include all of the agreement’s
    essential terms. See Nomanbhoy Family Ltd. Partnership v. McDonald’s Corp., 
    579 F. Supp. 2d 1071
    , 1095-97 (N.D.Ill. 2008); Kasowitz, Benson, Torres & Friedman, LLP v. Duane Reade, 
    98 A.D. 3d 403
    , 404, 
    950 N.Y.S. 2d 8
    , 9-10 (2012). In this case, a review of the emails upon which
    Steve relies are insufficient to establish an agreement regarding Christina’s college expenses.
    ¶ 67   On January 25, 2020, Steve sent an email to Lynn stating, in relevant part:
    “This is confirming our agreement with regard to Christina’s attendance at the University
    of Denver and our mutual agreement to each pay for half of her undergraduate college
    18
    No. 1-21-1187
    tuition and expenses. *** Per our conversation today, we each agreed to pay ½ of the total
    costs for Christina to attend the University of Denver. *** Based on this agreement, please
    confirm you will agree to an agreed order with regard to college and we will have that
    prepared.”
    ¶ 68   On January 26, 2020, Lynn responded to the email, stating in relevant part:
    “Yes, I agree to Christina attending the University of Denver and she can officially commit.
    *** We should know the details of any additional aid in the next 2 weeks and can move
    forward at that time with more specific numbers. *** We can put this into a formal
    agreement after we have agreed on the calculations and numbers. And then we can have a
    judge enter the Agreed Order.”
    ¶ 69   The above emails clearly show there were essential terms that were never agreed upon. For
    example, Lynn indicated that the parties could move forward with more specific numbers after
    they obtained further details of any additional aid Christina might receive. Moreover, “the emails
    make clear that both parties thought it essential that there be a written document that once and for
    all articulated the final understanding on the essential terms.” Nomanbhoy Family Ltd.
    Partnership, 
    579 F. Supp. 2d at 1096
    .
    ¶ 70   Thus, we hold that the trial court’s finding that the parties never reached an agreement to
    equally share Christina’s college expenses was not against the manifest weight of the evidence.
    We also hold that given the disparity in the parties’ respective incomes and resources, the court
    did not err by ordering Steve to pay 80% of Christina’s college expenses and Lynn to pay 20%.
    ¶ 71   Section 513 of the Dissolution Act authorizes a trial court to award educational expenses
    to a non-minor child “as equity may require.” 750 ILCS 5/513(a) (West 2018). “In awarding
    educational expenses for adult children, the court should consider (1) the present and future
    19
    No. 1-21-1187
    financial resources available to the parties, (2) the standard of living the child would have enjoyed
    had the parents remained married, (3) the child’s financial resources, and (4) the child’s academic
    performance.” In re Marriage of Budorick, 
    2020 IL App (1st) 190994
    , ¶ 83 (citing section
    513(j)(1)-(4) of the Dissolution Act). A trial court’s decision to award educational expenses is
    reviewed for an abuse of discretion. In re Marriage of Thomsen, 
    371 Ill. App. 3d 236
    , 243 (2007).
    ¶ 72   Steve argues that the trial court abused its discretion in requiring Lynn to contribute only
    20% of the cost of Christina’s college expenses. In support of this contention, Steve claims that
    Lynn judicially admitted through her testimony and pleadings that she could contribute at least
    25% of the cost of Christina’s college expenses.
    ¶ 73   Steve contends that the following testimony by Lynn constitutes the judicial admission:
    “Q. So jump forward, now Christina is at Michigan State, not asking that she leave
    Michigan State, you indicated a willingness to contribute towards it. Do you know what
    you are able to do, in your view, as to how much you can contribute towards her
    college?
    A. I would say, say between 6 – to $8,000 a year.
    Q. And what is, to your knowledge, the net amount of Michigan State after any aid that
    Christina gets?
    A. I’m not sure. I know she got some scholarships, and I believe it’s down to about
    40,000 now, maybe a little bit under 40,000, and I could about 6 – to 8,000.”
    ¶ 74   Lynn’s testimony does not constitute a judicial admission. A statement does not constitute
    a judicial admission when the party’s testimony is uncertain or amounts to an estimate or opinion.
    Hall v. Cipolla, 
    2018 IL App (4th) 170664
    , ¶ 106; Dunning v. Dynegy Midwest Generation, Inc.,
    
    2015 IL App (5th) 140168
    , ¶ 50. Lynn’s testimony shows that she was equivocal regarding the
    20
    No. 1-21-1187
    amount she could contribute towards Christina’s college expenses and provided a range of
    numbers, rather than a concrete single number.
    ¶ 75   Steve also argues that Lynn misrepresented her financial condition, where she failed to
    disclose the substantial sums of money she received from her father. Steve points out that Lynn is
    a beneficiary of her father’s trust and represented on a loan application that she owned real property
    valued at $700,000.
    ¶ 76   Here, the record shows that both parties submitted various financial documents to the trial
    court regarding their respective incomes and financial resources. The trial court reviewed these
    documents, heard the parties’ testimony concerning their respective current incomes and debts,
    and was able to weigh the credibility of each party. The trial court was in a better position than
    this court to evaluate and determine what percentage each party should contribute towards
    Christina’s college expenses. Under these circumstances, we cannot say that the court abused its
    discretion in apportioning Christina’s college expenses.
    ¶ 77                               3. Petition for Attorney Fees
    ¶ 78   Steve’s final argument is that the trial court erred in denying his petition for attorney fees
    after it granted his motion for sanctions pursuant to Illinois Supreme Court Rule 137. “The
    determination of whether to grant a motion for sanctions is a matter committed to the sound
    discretion of the trial court, as is the assessment of a monetary award once sanctionable pleading
    has been found.” Century Road Builders v. City of Palos Heights, 
    283 Ill. App. 3d 527
    , 531 (1996)
    (internal citations omitted); see also Sterdjevich v. RMK Management Corp., 
    343 Ill. App. 3d 1
    ,
    22 (2003) (an award of attorney fees under Rule 137 is discretionary). We will not substitute our
    judgment for that of the trial court by reweighing the evidence or the discretionary factors upon
    which the court relied in denying the petition for attorney fees. Therefore, we see no abuse by the
    21
    No. 1-21-1187
    court in denying Steve’s request for attorney fees.
    ¶ 79                                   III. CONCLUSION
    ¶ 80   For the foregoing reasons we find: (1) the trial court erred in finding that Lynn’s claim for
    child support arrearage was barred by laches and equitable estoppel; and (2) the court abused its
    discretion when it determined that the additional income Steve earned from working at
    Resurrection Healthcare could not be considered in calculating his child support obligation.
    Therefore, these rulings are reversed, and the case is remanded to the trial court to recalculate
    Steve’s child support obligation and arrearage.
    ¶ 81   We affirm the trial court’s rulings: (1) as to its calculation of the downward modification
    of Steve’s child support obligation; (2) making the modification of child support retroactive to
    June 2020, rather than February 2020; (3) finding that the parties did not have an agreement to
    equally share Christina’s college expenses; (4) allocating the parties’ respective contributions
    towards Christina’s college expenses; and (5) denying Steve’s petition for attorney fees.
    ¶ 82   Affirmed in part and reversed in part; cause remanded for further proceedings.
