SAPCR Mootness After Later Modification Order | Kacerova v. Garrett (2026)

Kacerova v. Garrett, 03-25-00125-CV, August 27, 2026.

On appeal from 200th District Court of Travis County

Synopsis

A pending appeal from an earlier final SAPCR modification order does not deprive the trial court of jurisdiction to hear and render a later Chapter 156 modification order. Once that later final order is signed, the appeal from the earlier order becomes moot and must be dismissed for want of jurisdiction.

Relevance to Family Law

This is a consequential jurisdiction-and-strategy decision for Texas family lawyers handling custody and possession litigation. In modification practice, parties often assume that an appeal freezes the field; Kacerova confirms that, in SAPCR cases, it does not. A trial court may continue to exercise its ongoing Chapter 156 modification authority even while an earlier final SAPCR order is on appeal, which means custody, access, support, and related conservatorship issues can be re-litigated and superseded before the appellate court reaches the merits of the earlier order. The same strategic lesson carries into divorce cases with children: if post-decree SAPCR issues are severable and modifiable, counsel must account for the real possibility that a later order will moot the pending appeal.

Case Summary

Fact Summary

The appeal in Kacerova v. Garrett challenged an earlier final SAPCR modification order. After the appeal was set for submission, the appellee moved to dismiss for lack of jurisdiction, arguing that the trial court had since rendered a new final SAPCR modification order on a later-filed petition to modify under Family Code Chapter 156. That later order was itself final and was already the subject of a separate appeal in the Third Court.

The appellant resisted dismissal by arguing that the trial court lacked jurisdiction to render the later modification order while the earlier order remained on appeal. Her position depended on the premise that plenary or appellate jurisdiction over the earlier SAPCR order barred the trial court from entering a subsequent final order modifying that same parent-child framework.

The Austin Court of Appeals rejected that premise. It held that the trial court retained jurisdiction to adjudicate the later Chapter 156 modification proceeding notwithstanding the pending appeal from the earlier order, and that the later final order therefore displaced the controversy presented in the earlier appeal.

Issues Decided

• Whether a Texas trial court retains jurisdiction under Family Code Chapter 156 to render a later final SAPCR modification order while an earlier final SAPCR order is pending on appeal.
• Whether rendition of that later final modification order renders the appeal from the earlier final SAPCR order moot.
• Whether the reasoning of In re E.W.N., 482 S.W.3d 150 (Tex. App.—El Paso 2015, no pet.), should control the jurisdictional analysis.

Rules Applied

The court relied principally on Texas Family Code Chapter 156, which authorizes modification of prior SAPCR orders. The opinion treats that statutory modification framework as a continuing source of trial-court authority that is not suspended merely because an earlier final SAPCR order is on appeal.

The court followed the line of authority holding that a pending appeal does not strip the trial court of jurisdiction to hear a later petition to modify in a SAPCR. The principal authorities were:

• In re Reardon, 514 S.W.3d 919, 921–30 (Tex. App.—Fort Worth 2017, orig. proceeding)
• Blank v. Nuszen, No. 01-13-01061-CV, 2015 WL 4747022, at *1–3 (Tex. App.—Houston [1st Dist.] Aug. 11, 2015, no pet.) (mem. op.)
• Hudson v. Markum, 931 S.W.2d 336, 337–38 (Tex. App.—Dallas 1996, no writ)

The court also addressed In re E.W.N., 482 S.W.3d 150 (Tex. App.—El Paso 2015, no pet.), which had concluded that a trial court lacked jurisdiction to render a new final SAPCR modification order while the prior order was on appeal. The Third Court noted that E.W.N. had been rejected by Reardon and later abandoned by the El Paso court itself in Kom v. Kom, No. 08-24-00022-CV, 2025 WL 1057731, at *3 n.2 (Tex. App.—El Paso Apr. 8, 2025, pet. denied) (mem. op.).

As to mootness, the court applied the principle that once a later valid final SAPCR modification order is rendered, an appeal concerning the superseded earlier order no longer presents a live controversy and must be dismissed for want of jurisdiction.

Application

The court’s analysis was direct and practical. Garrett’s motion to dismiss presented a threshold jurisdictional fact: after the appealed SAPCR order was signed, the trial court adjudicated a later Chapter 156 petition to modify and rendered another final SAPCR order. That later order did not merely supplement the prior judgment; it modified it and became the new operative order governing the parties’ parent-child rights and duties.

Kacerova attempted to avoid mootness by attacking the validity of the later order itself. Her argument was that if the trial court lacked jurisdiction to sign the later modification order during the pendency of the first appeal, then the later order could not moot anything. The viability of the motion to dismiss therefore turned on whether Texas law recognizes continuing trial-court authority to hear a new modification proceeding during appeal.

The Third Court aligned itself with Reardon and the authorities following it. In doing so, it treated SAPCR modification jurisdiction as materially different from the more rigid jurisdictional assumptions that sometimes govern ordinary civil judgments. Family Code Chapter 156 contemplates ongoing judicial supervision and repeated modification when statutory standards are met. The court was persuaded that this statutory structure allows a trial court to entertain a new modification case even though an earlier SAPCR order remains under appellate review.

Once the court concluded that the later order was jurisdictionally valid, the rest followed cleanly. The earlier order was no longer the live source of the parties’ rights and obligations; it had been overtaken by a subsequent final modification order. Because the appellate court could no longer grant effectual relief as to the earlier order alone, the pending appeal was moot and had to be dismissed for want of jurisdiction.

Holding

The Third Court held that a trial court does not lose jurisdiction to render a later final SAPCR modification order under Family Code Chapter 156 merely because an earlier final SAPCR order is on appeal. In reaching that conclusion, the court expressly followed In re Reardon, Blank v. Nuszen, and Hudson v. Markum, and declined to follow the abandoned reasoning of In re E.W.N.

The court further held that, because the later final modification order was validly rendered, the appeal from the earlier final SAPCR order became moot. The proper disposition was dismissal for want of jurisdiction rather than resolution of the merits of the earlier order.

Practical Application

For family-law litigators, Kacerova should change how you evaluate appellate leverage in modification cases. A notice of appeal from an adverse SAPCR order is no longer enough—if it ever was—to preserve a stable appellate target. If circumstances continue to evolve, the opposing party may file a new Chapter 156 petition, obtain a later final order, and thereby undercut or eliminate the practical value of the first appeal.

This has several immediate consequences:

• In custody and possession cases, counsel should assess whether appellate relief may be overtaken by anticipated factual developments before the appeal is decided.
• When defending an appeal, consider whether a later modification petition is both substantively warranted and strategically capable of superseding the appealed order.
• When prosecuting an appeal, do not assume the appellate court will ever reach the merits if the trial court signs a later final modification order.
• In advising clients, explain that appellate success may become academic if a new final SAPCR order replaces the one under review.
• If a later modification proceeding is filed, coordinate the trial and appellate strategy together; treating them as separate silos is a mistake.
• In post-divorce cases involving conservatorship, possession, access, or support, build a record with the possibility in mind that the “real” battleground may shift from the pending appeal to the next modification trial.

This decision also has briefing implications. If your opponent moves to dismiss the earlier appeal as moot, a generalized assertion that the trial court lacked jurisdiction because of the pending appeal is unlikely to succeed in the Third Court after Kacerova. Any responsive strategy must grapple with Reardon and the now-weakened status of E.W.N..

Checklists

Preserving Value in a SAPCR Appeal

• Determine whether any new Chapter 156 petition is pending or likely to be filed during the appeal.
• Evaluate whether changed circumstances could produce a later final order before appellate disposition.
• Advise the client that the existing appeal may become moot if a new final modification order is signed.
• Monitor the trial-court docket continuously during appeal.
• Calendar hearings, submissions, and trial settings in any later modification action.
• Consider whether emergency appellate relief is realistically available and legally supportable, rather than assuming the appeal alone protects the client’s position.

Defending Against Mootness

• Confirm whether the later order is in fact final.
• Analyze whether the later order truly modifies the order on appeal or instead addresses distinct relief.
• Review whether the later proceeding was brought under Chapter 156 and resulted in a new operative SAPCR framework.
• Assess whether any issue in the earlier appeal survives independently of the later order.
• Prepare to address Reardon, Blank, Hudson, and Kacerova directly rather than relying on abstract jurisdiction arguments.
• If arguing against mootness, identify a concrete form of effectual relief the appellate court can still grant.

Using a Later Modification Proceeding Strategically

• Evaluate whether there is a good-faith factual and statutory basis for a new modification petition.
• Plead for relief that will produce a final, operative order if granted.
• Build a clear record showing that the requested modification is based on current circumstances, not a collateral attack on the appeal.
• Obtain a final order with unambiguous modification language.
• Once the later final order is signed, consider a motion to dismiss the earlier appeal as moot.
• Be prepared for a separate appeal from the later order and preserve error accordingly.

Avoiding the Non-Prevailing Party’s Problem

• Do not assume a pending appeal strips the trial court of SAPCR modification jurisdiction.
• Do not rely on In re E.W.N. without acknowledging its erosion and the authorities rejecting it.
• Do not let the appellate case proceed in isolation from ongoing trial-court modification litigation.
• Do not wait until submission to investigate whether a later final order has superseded the appealed order.
• Do not frame appellate strategy without considering whether a later order may become the only order that matters.
