Material and Substantial Change Under Family Code 156.101 | Janaka v. Hutagaol (2026)

Jaka Janaka v. Rina Sefrin Hutagaol, 01-24-00157-CV, June 30, 2026.

On appeal from 328th District Court, Fort Bend County, Texas

Synopsis

Family Code section 156.101(a)(1) does not allow a possession modification merely because the movant alleges false CPS reporting, interference, or noncompliance with the existing schedule. The movant must prove a threshold material and substantial change since the prior order or the underlying mediated settlement agreement, and when the evidence is conflicting, the trial court retains broad discretion to reject the modification request.

Just as importantly, Janaka v. Hutagaol reinforces the appellate reality that credibility-driven modification cases are difficult to reverse, particularly when filed shortly after a decree entered on an MSA.

Relevance to Family Law

This opinion matters directly to Texas custody and possession litigation because it is a reminder that modification is not a vehicle to relitigate post-decree co-parenting grievances unless those grievances amount to a provable material and substantial change under Family Code section 156.101(a)(1). For family-law litigators, the case is especially useful in post-divorce disputes involving CPS allegations, possession friction, extracurricular disagreements, and claims of parental alienation. It also has broader strategic importance in divorce practice: when the underlying decree follows a mediated settlement agreement, counsel should expect trial and appellate courts to scrutinize whether the alleged “change” is truly new, substantial, and outcome-relevant rather than simply a continuation of conflict that was already present around the time of settlement.

Case Summary

Fact Summary

The parties divorced in late 2022 after signing a mediated settlement agreement in September 2022. The agreed decree appointed both parents joint managing conservators, gave Janaka primary custody, awarded Hutagaol specified possession, and required her to pay monthly child support. Within a matter of months, Janaka filed a modification suit seeking tighter restrictions on Hutagaol’s possession and an increase in support. Only the possession ruling was at issue on appeal.

At trial, Janaka’s theory was that circumstances had materially and substantially changed because Hutagaol allegedly made a false CPS report, failed to comply with the possession schedule, and interfered with the children’s extracurricular activities. He characterized these events as evidence that she could not effectively co-parent and that the children were being adversely affected.

The CPS issue arose after the parties’ teenage daughter left Janaka’s home following a verbal altercation. Hutagaol picked the child up and contacted CPS. Janaka argued the report was false and designed to alienate the children from him, emphasizing that CPS ultimately found no abuse or neglect. Hutagaol testified that she contacted CPS because the child had run away, reported a panic reaction after the confrontation, and expressed a desire not to continue living with her father. She further testified that, based on her own experiences during the marriage, she believed agency involvement was necessary to assess the daughter’s safety.

The trial court denied the requested modification, found no material and substantial change in circumstances, found that the requested relief was not in the children’s best interest, and further found that the suit had been filed frivolously or with the design to harass Hutagaol. The trial court awarded Hutagaol $20,000 in attorney’s fees. On appeal, Janaka challenged the findings on material and substantial change and frivolousness.

Issues Decided

• Whether the trial court abused its discretion in finding no material and substantial change in circumstances under Texas Family Code section 156.101(a)(1) sufficient to justify modification of possession.
• Whether allegations of false CPS reporting, noncompliance with the possession schedule, and interference with extracurricular activities compelled a finding of changed circumstances.
• Whether the trial court abused its discretion in rejecting the movant’s credibility-based account where the evidence was disputed.
• Whether the trial court abused its discretion in finding that the modification suit was filed frivolously or with the design to harass and in awarding attorney’s fees.

Rules Applied

Texas Family Code section 156.101(a)(1) permits modification of an order governing possession or access if modification is in the child’s best interest and if the circumstances of the child, a conservator, or another affected person have materially and substantially changed since the earlier of the prior order or the mediated settlement agreement on which that order was based.

The court relied on established First Court of Appeals authority emphasizing that material and substantial change is a fact question and a threshold gatekeeping requirement intended to prevent repetitive relitigation of custody-related orders. The opinion specifically invokes Nellis v. Haynie, 596 S.W.3d 920 (Tex. App.—Houston [1st Dist.] 2020, no pet.), for the proposition that the inquiry is case-specific and committed to the factfinder. It also cites Smith v. Karanja, 546 S.W.3d 734 (Tex. App.—Houston [1st Dist.] 2018, no pet.), for the principle that the threshold requirement exists to prevent constant relitigation and for examples of circumstances that may qualify as material and substantial changes.

On standard of review, the court applied the familiar abuse-of-discretion framework used in SAPCR modification appeals. Under Trammell v. Trammell, 485 S.W.3d 571 (Tex. App.—Houston [1st Dist.] 2016, no pet.), and Townsend v. Vasquez, 569 S.W.3d 796 (Tex. App.—Houston [1st Dist.] 2018, pet. denied), legal and factual sufficiency are not independent grounds of error but are components of the abuse-of-discretion analysis. In a bench trial, the trial judge is the sole judge of witness credibility and the weight to assign conflicting testimony.

Application

The court’s analysis is strategically important because it treats Janaka’s evidence as insufficient not in the abstract, but because each asserted “change” depended on factual inferences the trial court was not required to accept. On the CPS issue, Janaka asked the appellate court to infer falsity and alienating intent from the fact that CPS closed the case without a finding of abuse. The court refused to make that leap. Instead, it emphasized that the trial judge heard competing accounts of why Hutagaol made the report and was entitled to credit her explanation that she contacted CPS out of concern after the daughter ran away and reported emotional distress. The closure of the CPS matter did not conclusively establish bad faith, particularly where the records reflected limitations in CPS’s contact with the children and where the agency did not affirmatively validate Janaka’s theory.

The same logic governed the allegations of noncompliance with the possession schedule and interference with extracurricular activities. The opinion frames these complaints as contested factual matters, not self-proving evidence of a statutory change. Even if the record showed parental friction, scheduling disputes, and conflict over the children’s activities, the trial court could reasonably view those facts as ordinary post-divorce conflict rather than a material and substantial change arising after the decree or MSA. That distinction is the center of the opinion. Modification requires more than proof that co-parenting has become difficult or that one parent believes the other is acting unreasonably.

The appellate court also underscored the timing. This suit was filed only months after the mediated settlement agreement and decree. In that setting, the threshold-change requirement carries special force because courts are alert to efforts to revisit an agreed possession structure before any genuinely new circumstances have developed. The opinion therefore functions as a caution against filing a near-immediate modification based on disputes that either existed before entry of the decree or are merely expected manifestations of an already contentious relationship.

Finally, because the trial court’s findings turned heavily on credibility, the appellate court gave substantial deference to the bench-trial record. Once the trial court was entitled to disbelieve Janaka’s version of events and accept Hutagaol’s, reversal became highly unlikely. The opinion is a straightforward but powerful restatement of how abuse-of-discretion review operates in modification appeals: where the evidence is conflicting and the findings rest on credibility determinations, the appellate court will not substitute its judgment for that of the trial judge.

Holding

The First Court of Appeals held that modification of possession under Family Code section 156.101(a)(1) requires proof of a material and substantial change in the circumstances of the child, a conservator, or another affected person since the earlier of the prior order or the underlying mediated settlement agreement. On this record, the trial court did not abuse its discretion in finding that Janaka failed to carry that threshold burden. Allegations of false CPS reporting, schedule noncompliance, and extracurricular interference did not compel modification where the evidence was disputed and the trial court could resolve credibility issues against the movant.

The court also held that the trial court did not abuse its discretion in finding that Janaka filed the suit frivolously or with the design to harass Hutagaol and in awarding her attorney’s fees. Although the opinion’s broader lesson lies in the threshold-change analysis, the affirmance on frivolousness should not be overlooked: a weak, credibility-dependent modification filed shortly after an agreed decree may create fee exposure if the trial court views the case as harassment rather than a legitimate effort to protect the children.

Practical Application

For practitioners, Janaka is a strong case to cite both offensively and defensively in possession-modification litigation. If you represent the respondent, the opinion provides a clean framework for arguing that allegations of interference, bad motives, or isolated post-decree disputes do not satisfy section 156.101(a)(1) absent persuasive proof of a real, consequential change arising after the operative baseline date. It is particularly useful when the movant tries to bootstrap a CPS investigation, school conflict, or extracurricular dispute into a statutory change without linking the event to a demonstrable deterioration in the child’s circumstances or the responding parent’s fitness.

If you represent the movant, the case is a warning that narrative alone is not enough. You need chronology, corroboration, and a theory of change that distinguishes newly arisen facts from preexisting parental conflict. In practical terms, that means anchoring every alleged development to the date of the prior order or underlying MSA and proving both novelty and significance. A CPS closure can cut against the movant if counsel overstates it as conclusive proof of falsity; unless the agency affirmatively found bad-faith reporting, the trial court may still credit a safety-based explanation.

The opinion also matters in case screening. Lawyers should think hard before filing a modification shortly after an agreed decree, especially one built on disputes that were foreseeable at the time of settlement. Early-filed modification suits invite the court to ask whether anything has truly changed or whether one party simply regrets the bargain. That question becomes even more dangerous when the requested relief seeks to narrow the other parent’s possession on a record of mixed evidence and mutual accusations.

Several strategic takeaways follow:

• Tie your proof to the statutory baseline date: the earlier of the prior order or the mediated settlement agreement.
• Distinguish changed circumstances from continuing conflict.
• Use third-party corroboration whenever possible, including school records, counselors, medical providers, neutral witnesses, and detailed communication logs.
• Be cautious in characterizing a CPS report as “false” unless the record supports more than a no-findings closure.
• Evaluate fee exposure under frivolous-filing standards before initiating an aggressive post-decree modification.

Checklists

Screening a Possession Modification Before Filing

• Identify the operative comparison date under Family Code section 156.101(a)(1):
• the date of the prior order; or
• the date of the mediated settlement agreement underlying that order, if earlier
• List each alleged change and ask whether it arose after that date.
• Separate genuinely new developments from ongoing co-parenting conflict that predated the decree.
• Evaluate whether the alleged facts affect the child, a conservator, or another affected person in a substantial way.
• Assess whether the requested modification is proportional to the alleged change.
• Consider whether the facts support best interest independently of the threshold change requirement.
• Analyze the risk that the court may view the suit as retaliatory, premature, or harassment-driven.

Building Proof of Material and Substantial Change

• Create a timeline beginning with the MSA and decree.
• Collect objective records:
• school attendance and performance
• counseling or therapy records, if admissible
• medical records
• extracurricular participation records
• law-enforcement or agency records
• Preserve complete communications rather than selected excerpts.
• Develop testimony from neutral witnesses where available.
• Show concrete impact on the child rather than relying on abstract complaints about co-parenting difficulty.
• Be prepared to explain why the complained-of conduct is materially different from what existed at the time of the decree.
• Anticipate and address credibility problems before trial.

Handling CPS-Related Allegations

• Obtain the full CPS file, not just the closure notation.
• Determine whether CPS made any affirmative findings relevant to motive, safety, or access to the children.
• Avoid equating “ruled out” or “unable to determine” with proof of a knowingly false report.
• Prepare for the other side to frame the report as a good-faith safety measure.
• If alleging bad-faith reporting, gather evidence of:
• inconsistent statements
• contemporaneous admissions
• timing suggesting leverage or retaliation
• patterns of interference tied to the report
• Show how the CPS allegation changed circumstances in a legally material way, not merely that it generated conflict.

Defending Against a Weak Modification Suit

• Frame the case around the threshold statutory requirement first.
• Emphasize the short time between decree and modification filing, if applicable.
• Show that the alleged facts are continuations of preexisting conflict rather than new changes.
• Highlight evidentiary gaps, selective texts, and lack of neutral corroboration.
• Reinforce the trial court’s role as sole judge of credibility in a bench trial.
• Preserve attorney’s-fees evidence and a frivolousness record where warranted.
• Request findings of fact and conclusions of law to fortify affirmance on appeal.

Avoiding the Non-Prevailing Party’s Mistakes

• Do not file quickly after an agreed decree unless the record clearly shows a new and substantial development.
• Do not assume that proving conflict proves statutory change.
• Do not overread a CPS closure as definitive proof of falsity or alienation.
• Do not base the case primarily on your client’s interpretation of motives without corroboration.
• Do not neglect the best-interest element while focusing on changed circumstances.
• Do not ignore the possibility of an attorney’s-fees award if the court perceives the suit as harassment.
