CROSSOVER: Guardianship order vacated for failure to personally serve proposed ward under Estates Code § 1051.103

In re Guardianship of Stewart, 10-24-00286-CV, June 25, 2026.

On appeal from County Court of Coryell County, Texas

Synopsis

Texas Estates Code § 1051.103(a)(1) requires personal service on a proposed ward age 12 or older for the specific guardianship application on which the court is asked to act. In Stewart, the Tenth Court held that service of Mother’s later-filed guardianship application did not cure Father’s failure to personally serve his own application on the proposed ward, and the attorney ad litem’s participation could not supply jurisdiction. The resulting guardianship order in Father’s favor was therefore void and had to be vacated.

Relevance to Family Law

For family-law litigators, Stewart is a service-and-jurisdiction case with obvious crossover value in SAPCRs, modification suits, enforcement proceedings, third-party interventions, and property-related probate disputes that orbit divorce litigation. The opinion reinforces a basic but highly weaponizable point: when a statute requires personal service tied to a particular pleading seeking particular relief, participation by counsel, actual notice, or litigation activity elsewhere in the case will not necessarily rescue a jurisdictional failure. In family litigation, that principle matters whenever a party seeks affirmative relief through a new petition, intervention, modification, guardianship-adjacent filing, or post-divorce proceeding and assumes that prior service in a related matter is enough.

Case Summary

Fact Summary

Father filed an application on January 2, 2024 seeking appointment as permanent guardian of the person of the parties’ adult son, Nathan. Mother was personally served and answered, first pro se and then through counsel, objecting to Father’s request and disputing incapacity and suitability. A citation also issued for Nathan, but the return reflected personal service on “David Stewart,” not Nathan. In other words, the record did not show that Nathan was ever personally served with Father’s application.

Despite that defect, the trial court appointed an attorney ad litem for Nathan on Father’s motion, and the ad litem filed an answer and appeared at the final hearing. The hearing began in June 2024 and was continued to July 12, 2024.

During that recess, Mother filed her own application for appointment as guardian of Nathan’s person and estate on July 1, 2024. Nathan was personally served with citation and Mother’s application on July 10, 2024. The hearing concluded two days later, with the attorney ad litem again appearing on Nathan’s behalf. Nathan himself was not shown to have been present.

The trial court later determined that Nathan was incapacitated and that a guardian of the person should be appointed, but not a guardian of the estate. After encouraging a possible co-guardianship arrangement and receiving no agreement, the court ultimately signed a final order on August 14, 2024 appointing Father—not Mother—as permanent guardian of Nathan’s person. Mother appealed, arguing among other things that the court never acquired personal jurisdiction over Nathan as to Father’s unserved application.

Issues Decided

• Whether Texas Estates Code § 1051.103(a)(1) requires personal service on a proposed ward age 12 or older for the specific guardianship application on which relief is sought.
• Whether personal service of a different party’s separate guardianship application can satisfy the service requirement for the application actually resulting in the guardianship order.
• Whether the participation of an attorney ad litem can cure the complete absence of personal service on the proposed ward for that specific application.
• Whether the order appointing Father as guardian was void for lack of personal jurisdiction over the proposed ward.

Rules Applied

The court relied principally on the statutory service framework in Chapter 1051 of the Texas Estates Code and the Supreme Court’s personal-jurisdiction analysis in In re Guardianship of Fairley, 650 S.W.3d 372 (Tex. 2022).

Key authorities included:

• Texas Estates Code § 1051.103(a)(1): the sheriff or other officer shall personally serve citation to appear and answer an application for guardianship on a proposed ward who is 12 years of age or older.
• Texas Estates Code § 1051.105: persons other than the proposed ward may waive notice or service, implying that the proposed ward may not.
• Texas Estates Code § 1051.055(e): an attorney ad litem may not waive personal service of citation for the proposed ward.
• In re Guardianship of Fairley, 650 S.W.3d 372 (Tex. 2022): technical defects in the method of service may be overcome where the proposed ward was actually personally served with the guardianship applications and then appeared through counsel, but service cannot be waived altogether.
• Luciano v. SprayFoamPolymers.com, LLC, 625 S.W.3d 1 (Tex. 2021) and Kawasaki Steel Corp. v. Middleton, 699 S.W.2d 199 (Tex. 1985): personal jurisdiction requires valid invocation through proper service.
• In re E.R., 385 S.W.3d 552 (Tex. 2012) and Wilson v. Dunn, 800 S.W.2d 833 (Tex. 1990): citation must issue and be served in the manner provided by law.
• Gauci v. Gauci, 471 S.W.3d 899 (Tex. App.—Houston [1st Dist.] 2015, no pet.) and In re Martinez, No. 04-07-00558-CV, 2008 WL 227987 (Tex. App.—San Antonio Jan. 30, 2008, orig. proceeding): failure to personally serve a proposed ward deprives the court of jurisdiction and renders the resulting order void.
• In re C.T.F., 336 S.W.3d 385 (Tex. App.—Texarkana 2011, no pet.): service of one pleading does not authorize relief on another pleading seeking different relief by a different party.

Application

The Tenth Court treated the dispositive problem not as a technical defect in service, but as an absence of service on Father’s application altogether. That distinction drove the result. Father argued that because Nathan had been personally served with Mother’s later-filed guardianship application before the final order was signed, and because the attorney ad litem had actively participated, the court had sufficient jurisdiction to appoint Father. The court rejected that position.

The opinion emphasized that Mother’s and Father’s applications were not interchangeable. They were filed by different parties and sought different affirmative relief. Service of Mother’s application therefore put Nathan on notice of Mother’s request for appointment, not Father’s. Under § 1051.103(a)(1), Nathan was entitled to personal service of the application “to appear and answer” the particular guardianship request at issue. The court would not collapse separate pleadings into one generic guardianship controversy for service purposes.

The court also distinguished Fairley. In Fairley, the proposed ward had indisputably been personally served with both guardianship applications; the question involved technical deficiencies in the method of service, later followed by a general appearance through the ad litem. Here, by contrast, Nathan was never personally served with Father’s application at all. Because Chapter 1051 does not allow the proposed ward to waive service, and because the attorney ad litem cannot waive personal service on the ward’s behalf, the ad litem’s participation could not bridge that gap.

Once the court characterized the problem as no service rather than defective service, the rest followed cleanly: no valid service meant no valid invocation of personal jurisdiction over Nathan as to Father’s application, and no personal jurisdiction meant the order appointing Father was void.

Holding

The court held that Texas Estates Code § 1051.103(a)(1) requires personal service of citation on a proposed ward age 12 or older for the particular guardianship application on which relief is sought. It is not enough that the ward was served with some other guardianship application filed in the same proceeding by a different party.

The court further held that the attorney ad litem’s answer and participation did not cure the failure to personally serve Father’s application. The Estates Code does not permit the proposed ward to waive service, and the attorney ad litem cannot waive personal service on the ward’s behalf.

Because Nathan was never personally served with Father’s guardianship application, the trial court lacked personal jurisdiction to enter an order appointing Father as guardian. The order was void, so the court vacated it and remanded for further proceedings.

Practical Application

For family-law practitioners, Stewart is a reminder that pleadings seeking affirmative relief must stand on their own service footing when the governing statute demands personal service. That lesson extends beyond guardianship contests between parents over an adult child. In divorce and SAPCR litigation, lawyers frequently treat related proceedings as part of one continuous dispute and become less disciplined about whether each new filing, intervention, counter-petition, modification request, or probate-adjacent application has been properly served on the correct party in the correct capacity. Stewart is a useful authority when you need to argue that one side obtained an order on a pleading your client was never required by statute to answer because service never occurred.

The case also has strategic value where opposing counsel tries to rely on actual notice, counsel participation, ad litem participation, or attendance at hearings as a substitute for statutorily required service. If the statutory scheme makes service jurisdictional, those facts may be irrelevant. In high-conflict family matters involving incapacitated adult children, adult disabled dependents, special-needs planning, trust disputes, or parallel probate proceedings, counsel should assume that each distinct application for relief requires its own service analysis.

At a minimum, practitioners should take away four operational points:

• Verify the return, not merely the issuance of citation.
• Match the service to the exact live pleading on which the court will act.
• Do not assume an ad litem appearance cures absent service.
• When attacking an adverse order, frame the problem as a complete lack of service rather than a mere defect in form if the record supports that characterization.

Checklists

Service Audit for Guardianship-Adjacent Family Cases

• Identify every live pleading seeking affirmative relief.
• Confirm which party filed each pleading and what distinct relief it requests.
• Determine whether a statute requires personal service for that specific pleading.
• Obtain and review the actual return of service, not just the citation request.
• Verify that the named person served matches the intended respondent or proposed ward.
• Verify that the document served was the correct application or petition.
• Confirm service occurred before the court ruled on that pleading.
• Preserve the clerk’s record showing any mismatch between the pleading filed and the pleading served.

Pre-Hearing Jurisdiction Check

• Review whether all necessary parties were personally served in the manner required by statute.
• Confirm whether any waiver is legally permitted for that category of party.
• If an ad litem is involved, confirm the limits of the ad litem’s authority regarding waiver of service.
• Raise service defects before the merits hearing if possible.
• Request that the court refrain from ruling on an unserved application.
• If the defect is discovered mid-hearing, make a clean record distinguishing lack of service from technical defect.
• Consider requesting abatement or continuance to complete valid service rather than risking a void order.

Offensive Use in Family Litigation

• Evaluate whether the opposing party obtained relief on a petition, intervention, or modification that was never properly served.
• Compare the relief granted in the order against the pleading actually served.
• Argue that service of one pleading does not authorize judgment on another pleading seeking different relief.
• Resist arguments based on actual notice alone where the statute requires formal service.
• Distinguish cases involving technical defects from cases involving no service at all.
• If the record shows no valid service, argue the resulting order is void rather than merely voidable.

Defensive Drafting and Docket Management

• When filing multiple related applications or amended requests for relief, request fresh citation as needed.
• Do not assume earlier service carries over to a later-filed or competing application.
• Track service returns in a dedicated jurisdiction checklist before final hearing.
• If another party files a competing application, confirm your client’s application was also personally served if required.
• Before submitting a proposed order, confirm the court’s ruling aligns only with pleadings that were properly served.
• Train staff to flag any return showing service on the wrong person, wrong address, or wrong document.

Family Law Crossover

This ruling can be weaponized in family litigation wherever an opponent asks the court to act on a pleading that was never properly served, especially when they try to hide behind participation, appearance, or actual notice. In a divorce, that may arise when a party seeks disproportionate property relief, post-decree enforcement, turnover-type remedies, or trust/probate-adjacent relief through an amended or supplemental pleading that was never formally served. In custody litigation, the same logic applies to interventions, modification petitions, relocation requests, grandparent access pleadings, or nonparent conservatorship claims where the statutory notice and service requirements are strict and tied to the pleading itself.

The more strategic lesson is framing. Stewart gives family lawyers a clean template for arguing that the defect is not procedural sloppiness but a failure to invoke personal jurisdiction as to the specific request for relief granted. If the other side served Petition A and won on Petition B, Stewart supports the position that the order is vulnerable because the responding party was never properly brought before the court on that particular claim. That is especially potent when the other side argues that counsel’s participation, an ad litem’s involvement, or a related proceeding should cure the problem. Under Stewart, those facts do not substitute for statutorily required service where service is a prerequisite to the court’s power to bind the affected person.
