A Day Late and a Dollar Short: Section 263.401 Automatic Dismissal Voids Late Extension | In re L.M. (2026)

In the Interest of L.M., a Child, 05-26-01297-CV, November 03, 2026.

On appeal from County Court at Law No. 1, Kaufman County, Texas

Synopsis

Texas Family Code § 263.401(a) automatically dismissed the Department’s termination suit when trial did not commence—and no extension was granted—by March 23, 2026. The extension order signed one day later was void, could not revive the trial court’s jurisdiction, and required vacatur of the subsequent termination order and dismissal of the suit.

Relevance to Family Law

In re L.M. is directly controlling in Department-filed termination and conservatorship proceedings subject to § 263.401. It reinforces that the statutory dismissal date is jurisdictional, not merely a docket-control deadline that can be waived, extended by agreement, or corrected after expiration. Although § 263.401 does not govern an ordinary divorce, private custody dispute, or marital-property case, the decision remains strategically important to family-law litigators handling consolidated SAPCRs, intervening relatives, competing conservatorship claims, or parallel proceedings involving DFPS. Counsel must determine which claims fall within the Department-filed suit, whether the statutory deadline affects the court’s authority to adjudicate those claims, and whether separate divorce, custody, or property issues remain pending in a proceeding supported by an independent jurisdictional basis.

Case Summary

Fact Summary

On March 20, 2025, the Department of Family and Protective Services filed suit seeking termination of Mother’s parental rights to L.M. and appointment of the Department as the child’s permanent managing conservator. On the same date, the trial court rendered a temporary order appointing the Department as L.M.’s temporary managing conservator.

That temporary appointment triggered the deadline in Texas Family Code § 263.401(a). The first Monday after the first anniversary of the temporary order was March 23, 2026. Unless trial commenced or the court granted a qualifying extension by that date, the court’s jurisdiction would terminate and the suit would be dismissed automatically.

The trial court did not commence trial by March 23. Nor did the record contain an extension granted on or before that date. Instead, on March 24, 2026—one day after the statutory deadline—the trial court signed an order purporting to retain the suit and reset the dismissal date to September 19, 2026.

Trial began months later, and the court ultimately terminated Mother’s parental rights and appointed the Department permanent managing conservator. The trial court signed a September 3, 2026 nunc pro tunc termination order to correct a scrivener’s error in the original judgment.

Mother appealed and requested findings of fact and conclusions of law. While considering motions to abate, the Fifth Court of Appeals independently identified the apparent jurisdictional defect. The court requested letter briefs explaining why the trial court had not lost jurisdiction, but no party responded.

Issues Decided

• Whether § 263.401(a) automatically dismissed the Department’s suit when trial did not commence and the court did not grant an extension by March 23, 2026.

• Whether an order signed on March 24, 2026, could extend the dismissal deadline after the trial court’s jurisdiction had already terminated.

• Whether the trial court possessed jurisdiction to conduct the later trial and sign the termination order.

• What disposition was required when the order under appellate review was void for lack of jurisdiction.

Rules Applied

Texas Family Code § 263.401(a) provides that, unless trial on the merits has commenced or an extension has been granted under subsection (b) or (b-1), the court’s jurisdiction terminates on the first Monday after the first anniversary of the temporary order appointing the Department temporary managing conservator. The suit is then automatically dismissed without the necessity of a dismissal order.

Section 263.401(b) permits the trial court to retain the suit for no more than 180 additional days if the court finds that extraordinary circumstances necessitate the child’s continued placement in the Department’s temporary managing conservatorship and that continuation of the appointment is in the child’s best interest. Those findings and the resulting extension must be granted before jurisdiction expires.

The court relied principally on the following authorities:

• In re C.S., 740 S.W.3d 448, 450, 452–55 (Tex. 2026), recognizing that the Legislature has made prompt resolution of termination proceedings a jurisdictional mandate and addressing what the record must show concerning a timely extension.

• In re G.X.H., 627 S.W.3d 288, 292 (Tex. 2021), holding that dismissal is mandatory and jurisdiction terminates when the trial court neither commences trial nor properly extends the deadline under § 263.401.

• In re H.S., 550 S.W.3d 151, 155 (Tex. 2018), establishing de novo review for questions implicating subject-matter jurisdiction.

• In re P.Z.F., 651 S.W.3d 147, 150 (Tex. App.—Dallas 2021, pet. denied), recognizing an appellate court’s authority to determine whether the underlying judgment is void and to enter the appropriate disposition.

• In re A.M., No. 07-19-00391-CV, 2020 WL 1174579, at *3 (Tex. App.—Amarillo Mar. 11, 2020, no pet.) (mem. op.), explaining that jurisdiction lost through automatic dismissal cannot be revived by a later order.

• In re A.F., No. 02-19-00117-CV, 2019 WL 4635150, at *11 (Tex. App.—Fort Worth Sept. 24, 2019, no pet.) (mem. op.), holding that an extension order rendered after the court had been divested of jurisdiction was void.

Application

The statutory calculation began with the March 20, 2025 temporary order appointing the Department temporary managing conservator. The first Monday after the first anniversary of that order was March 23, 2026. That was the operative dismissal date under § 263.401(a).

The record did not show that trial commenced by March 23. It also did not show that the trial court granted an extension on or before that date. Accordingly, the statute operated automatically: the trial court’s jurisdiction terminated, and the suit was dismissed without the need for a separate dismissal order.

The March 24 order could not alter that result. By the time the trial court signed the order, it no longer had jurisdiction over the suit. The purported extension therefore was void and could not retroactively restore authority that the statute had already withdrawn.

Because jurisdiction was not revived, the trial court lacked authority to conduct the later trial or render a judgment terminating Mother’s parental rights. The nunc pro tunc character of the September 3 order did not cure the problem. A nunc pro tunc order may correct a clerical error in an otherwise valid judgment, but it cannot supply subject-matter jurisdiction or validate proceedings conducted after jurisdiction expired.

The appellate court also did not treat the parties’ silence, requests for abatement, or apparent participation in the later proceedings as a waiver. Subject-matter jurisdiction cannot be created by agreement, participation, acquiescence, or failure to object. Once the appellate record disclosed the jurisdictional defect, the court was obligated to address it.

Holding

The Fifth Court of Appeals held that the Department’s suit was automatically dismissed on March 23, 2026. Trial had not commenced, and no extension had been granted by the statutory deadline, so § 263.401(a) terminated the trial court’s jurisdiction by operation of law.

The court further held that the March 24, 2026 extension order was void. An extension signed after § 263.401(a) has already terminated jurisdiction cannot revive the case or retroactively extend the dismissal date.

Finally, the court held that the trial court lacked jurisdiction to conduct the subsequent trial or terminate Mother’s parental rights. The appellate court vacated the September 3, 2026 termination order, dismissed the underlying case, and dismissed the appeal. It denied the pending motions to abate as moot.

Practical Application

For counsel in a DFPS termination case, the § 263.401 date should be treated as a jurisdictional expiration date rather than a scheduling target. The key event is not when a proposed extension order is submitted, when the court orally indicates that an extension will be granted, or when the parties agree to a later trial setting. The record must establish that trial timely commenced or that a valid extension was granted before the statutory deadline.

Counsel seeking an extension should obtain a signed order well in advance of the deadline. The order should include the statutory findings concerning extraordinary circumstances and the child’s best interest, specify the new dismissal date, and comply with the 180-day limitation. Waiting until the final business day creates unnecessary risk involving presentment, signature, filing, rendition, and the sufficiency of the record.

Appellate counsel should independently calculate the § 263.401 deadline in every Department-filed appeal. The absence of an objection below does not eliminate the issue. If the trial court’s jurisdiction expired, findings of fact, mediation, abatement, or merits briefing cannot validate the resulting judgment.

The same analysis should inform representation of intervening grandparents, alleged fathers, foster parents, or relatives asserting conservatorship claims in a Department case. Counsel should determine whether a client’s pleadings are dependent on the Department’s suit, whether claims have been severed into a proceeding with an independent jurisdictional basis, and what remains justiciable if the DFPS action is automatically dismissed.

In a divorce or private custody case running parallel to a Department proceeding, practitioners should avoid assuming that the § 263.401 dismissal necessarily disposes of every issue between the parties. Instead, counsel should identify the cause number, pleadings, consolidation or transfer orders, parties, and jurisdictional basis for each claim. Divorce dissolution and marital-property claims may remain pending even when a Department-filed termination action cannot proceed, but the court’s authority over child-related claims must be evaluated carefully in light of the governing orders and statutory framework.

Checklists

Calculate and Calendar the Dismissal Date

• Obtain the signed temporary order appointing the Department temporary managing conservator.

• Identify the date the trial court rendered the temporary appointment; do not rely solely on the petition’s filing date.

• Calculate the first anniversary of the temporary appointment.

• Identify the first Monday following that anniversary.

• Confirm the calculation against the clerk’s record and the court’s docket.

• Calendar internal reminders at least 90, 60, and 30 days before the dismissal date.

• Verify that the court provided the notice required by § 263.401(a), while recognizing that counsel should not rely exclusively on court-generated notice.

Secure a Timely Extension

• File any motion to retain sufficiently before the statutory deadline.

• Present evidence supporting extraordinary circumstances.

• Establish why the child must remain in the Department’s temporary managing conservatorship.

• Establish that continuation of the appointment is in the child’s best interest.

• Obtain an express ruling before jurisdiction expires.

• Obtain a signed, file-stamped order rather than relying on an anticipated ruling or proposed order.

• Ensure the order includes the necessary statutory findings.

• State the new dismissal date clearly.

• Confirm that the extension does not exceed the statutory 180-day period.

• Preserve the motion, evidence, ruling, and signed order in the clerk’s and reporter’s records.

Confirm That Trial Timely Commenced

• Determine whether the proceeding was actually a trial on the merits rather than a status conference, pretrial hearing, or docket call.

• Identify the precise date on which trial allegedly commenced.

• Secure a reporter’s record reflecting the commencement of trial.

• Ensure the record demonstrates substantive commencement rather than a nominal appearance intended only to avoid dismissal.

• Object to any unexplained recess or delay that could create a dispute about whether trial genuinely commenced.

• Recalculate any extended deadline and confirm that trial began within the extension period.

Audit the Record Before Final Judgment

• Confirm that the original and any extended dismissal dates are reflected accurately in the record.

• Verify that the extension order was rendered before the original deadline.

• Compare the date of rendition with the date of signing and filing.

• Confirm that the order contains the findings required by § 263.401(b).

• Review docket-sheet entries, but do not assume they substitute for a valid order or complete appellate record.

• Raise any jurisdictional defect before proceeding to trial or requesting final relief.

• Avoid relying on a nunc pro tunc order to correct a jurisdictional failure.

Preserve and Present the Issue on Appeal

• Recalculate the § 263.401 deadline independently from the parties’ appellate arguments.

• Include the temporary managing-conservatorship order in the clerk’s record.

• Include every motion, ruling, and order concerning retention or extension.

• Request the reporter’s record for any hearing at which an extension allegedly was granted.

• Address whether the record shows a timely rendition under controlling precedent.

• Explain why participation, consent, or failure to object cannot confer subject-matter jurisdiction.

• Request vacatur of the void order and dismissal of the underlying suit when jurisdiction expired.

• Respond promptly to any appellate request for jurisdictional briefing.

Evaluate Parallel or Consolidated Family-Law Claims

• Identify every pending claim, party, and cause number.

• Determine whether divorce, private conservatorship, possession, support, or property claims have an independent jurisdictional basis.

• Review all transfer, consolidation, severance, and intervention orders.

• Determine which claims belong to the Department-filed suit governed by § 263.401.

• Assess whether automatic dismissal affects intervenors’ or relatives’ requested relief.

• Seek severance or other appropriate relief before the deadline when necessary to protect independently viable claims.

• Avoid assuming that dismissal of the Department’s case either resolves or preserves separate divorce, custody, or property claims.
