Adam Horwitz v. City of Denton, et al., 02-26-00025-CV, March 19, 2026.
On appeal from the 442nd District Court, Denton County, Texas.
Synopsis
In an accelerated appeal from an interlocutory order, the notice of appeal must be filed within 20 days of the signing of the order. Under Texas Rule of Appellate Procedure 28.1(b), the filing of a motion for new trial does not extend this jurisdictional deadline, making any notice filed after the 20-day window (plus any applicable 15-day extension period) untimely and necessitating dismissal.
Relevance to Family Law
While Horwitz arises from a civil plea to the jurisdiction, its procedural trap is a minefield for family law litigators. Many critical family law orders—such as those appointing a receiver, granting or denying a temporary injunction, or resolving jurisdictional disputes under the UCCJEA—are classified as accelerated appeals. Litigators accustomed to the 90-day “buffer” provided by a Motion for New Trial in final decrees will find themselves barred from appellate review if they apply that same logic to interlocutory orders in a divorce or SAPCR.
Case Summary
Fact Summary
Appellant Adam Horwitz attempted to appeal two interlocutory orders: one granting a plea to the jurisdiction and another granting a Rule 91a motion to dismiss. The trial court signed these orders on October 13, 2025. Because the orders dismissed claims against only six of the seventeen named defendants, they were interlocutory rather than final judgments. Horwitz, operating under the assumption that his filing of a motion for new trial extended his appellate timetable, did not file his notice of appeal until January 9, 2026—nearly three months after the orders were signed. He argued that the trial court’s docket had labeled the orders as “Final Order/Judgment,” which reinforced his belief that the standard 90-day deadline applied.
Issues Decided
- Does the filing of a motion for new trial extend the deadline to file a notice of appeal in an accelerated, interlocutory appeal?
- Does a trial court’s docket entry labeling an order as “final” override the legal reality that the order is interlocutory for purposes of the appellate timetable?
Rules Applied
- Tex. R. App. P. 26.1(b): Establishes that the notice of appeal for accelerated appeals must be filed within 20 days after the order is signed.
- Tex. R. App. P. 28.1(a) & (b): Defines appeals from interlocutory orders as accelerated and explicitly states that a motion for new trial will not extend the time to perfect the appeal.
- Tex. Civ. Prac. & Rem. Code § 51.014(a)(8): Authorizes interlocutory appeals for orders granting or denying a plea to the jurisdiction by a governmental unit.
- Lehmann v. Har-Con Corp., 39 S.W.3d 191 (Tex. 2001): Clarifies that a judgment is only final if it disposes of all remaining parties and claims in the record.
Application
The Second Court of Appeals determined that because the October 13 orders left unresolved claims and parties, they were interlocutory. Consequently, the appeal was governed by Rule 28.1, which mandates an accelerated timeline. The court rejected Horwitz’s reliance on his motion for new trial, noting that Rule 28.1(b) is unambiguous: such motions do not extend the 20-day deadline.
The court further addressed the “trap” created by the trial court’s docketing system. Although the docket labeled the orders as “Final Order/Judgment,” the court held that the substance of the order and the state of the record control finality, not the clerk’s docket entry. Because the notice of appeal was filed months past the 20-day deadline, the court concluded it lacked jurisdiction to hear the merits.
Holding
The court held that it lacks jurisdiction over any interlocutory appeal where the notice of appeal is not filed within the 20-day window required by Rule 26.1(b). The court reaffirmed that the filing of a motion for new trial is ineffective to extend appellate deadlines in the context of an accelerated appeal.
The court further held that a litigant’s reasonable belief regarding finality—even if prompted by misleading docket notations—cannot create appellate jurisdiction where the notice of appeal is untimely under the Texas Rules of Appellate Procedure.
Practical Application
For the family law practitioner, this case serves as a stark reminder to audit the “finality” of every order immediately. If you are appealing an order that does not dispose of the entire case (like a temporary injunction or a jurisdictional ruling), you must file your notice of appeal within 20 days. Do not wait for a ruling on a motion for new trial or a motion for reconsideration. If you are unsure if an order is final or interlocutory, the safest course of action is to file the notice of appeal within 20 days to preserve the court’s jurisdiction.
Checklists
Determining the Appellate Timeline
- Identify if the order is interlocutory (e.g., temporary injunction, receiver appointment, special appearance denial).
- Verify if the order disposes of all parties and all claims (the Lehmann test).
- If any party or claim remains, treat the appeal as accelerated.
- Check for specific statutes in the Family Code or Civil Practice & Remedies Code that characterize the specific order as “accelerated.”
Avoiding the 20-Day Trap
- Calendar the notice of appeal for 20 days from the date of the judge’s signature.
- Do not rely on a Motion for New Trial to extend the deadline.
- If the 20-day deadline is missed, file a Motion for Extension of Time and the Notice of Appeal within the 15-day “grace period” allowed by Rule 26.3.
- Disregard docket labels like “Final” or “Case Closed” if the order itself does not actually resolve all issues for all parties.

Full Opinion
Family Law Crossover
In Texas family law, the “Crossover” utility of Horwitz is significant for defense strategy. If an opposing party is aggrieved by an interlocutory order—such as an order denying a stay in a multi-state custody battle—and they mistakenly file a Motion for New Trial instead of an immediate Notice of Appeal, they are effectively waiving their right to interlocutory review.
Strategic litigators can weaponize this by remaining silent until the 20-day (and subsequent 15-day extension) window has closed. Once the deadline has passed, the interlocutory order becomes unappealable until a final judgment is entered. In many divorce cases, this means the “temporary” status quo remains in place for months or years, with the opponent having lost their only window for immediate appellate correction. This creates massive settlement leverage, as the window for interlocutory relief is narrow and unforgiving.
