CROSSOVER: Unsworn Special Appearance Is Dead on Arrival: Dallas Court Affirms Rule 120a Strict-Compliance | Tan v. Moore (2026)

Chang Qing Tan v. Michelle Moore, 05-25-01468-CV, July 01, 2026.

On appeal from 429th Judicial District Court, Collin County, Texas

Synopsis

The Dallas Court of Appeals reaffirmed that Texas Rule of Civil Procedure 120a is a strict-compliance rule: a special appearance must be sworn or properly verified, or it is ineffective to challenge personal jurisdiction. If the motion is unsworn, the trial court may deny it without ever reaching minimum contacts, purposeful availment, or fair-play arguments.

Relevance to Family Law

This holding matters in family law because personal-jurisdiction fights routinely arise in divorce, SAPCR, modification, enforcement, and property-division litigation involving out-of-state or foreign-resident spouses, parents, and third parties. While interlocutory appeal rules differ in Family Code cases, the procedural trap does not: if a respondent or counter-respondent files an unsworn special appearance in a suit affecting conservatorship, support, divorce-related property claims, or post-divorce enforcement, the jurisdictional challenge may fail at the threshold, leaving the court free to proceed against that party without any merits determination on contacts with Texas.

Case Summary

Fact Summary

The underlying case was a negligence suit arising from an automobile collision in Plano. The plaintiff alleged that the defendant caused the crash by making an unsafe lane change and sought damages for significant personal injuries. Her petition alleged the defendant was a Texas resident and that venue was proper in Collin County because he resided there when the cause of action accrued.

Service became an issue. A process server was unable to complete traditional service and learned from the defendant’s ex-wife that he had moved back to China. The plaintiff then obtained substituted service by email. In response, the defendant filed a special appearance asserting that he was a resident of China, was only visiting Texas at the time of the accident, had not purposefully availed himself of Texas, and lacked the types of ongoing contacts that would support general jurisdiction. He later filed a supplemental special appearance attaching an affidavit from his daughter, who described his move back to China after his divorce and stated that he had no Texas property, business operations, bank accounts, office, or residence.

The problem was procedural, not substantive. Neither the original special appearance nor the supplemental special appearance was sworn or verified. Although the daughter’s affidavit was attached to the supplement, it did not state that the facts in the special appearance itself were true and correct, did not indicate that she had read the pleading, and did not even adequately verify the affidavit in the manner Rule 120a requires. The trial court denied the special appearance, and the Dallas Court affirmed without addressing the defendant’s actual jurisdictional arguments.

Issues Decided

• Whether Texas Rule of Civil Procedure 120a(1) requires a special appearance to be made by sworn motion.
• Whether an unsworn special appearance is ineffective to challenge personal jurisdiction.
• Whether an attached affidavit can cure an unsworn special appearance when the affidavit does not verify the facts alleged in the special appearance itself.

Rules Applied

The court relied on the text of Texas Rule of Civil Procedure 120a(1), which expressly provides that a special appearance must be made by sworn motion. It also referenced Rule 120a(3), which governs proof on special appearance practice and requires affidavits to be made on personal knowledge.

The court grounded its analysis in settled Texas Supreme Court authority and repeated Dallas precedent:

• TEX. R. CIV. P. 120a(1) — a special appearance must be brought by sworn motion.
• TEX. R. CIV. P. 120a(3) — affidavits used in special appearance practice must satisfy personal-knowledge requirements.
• Dawson-Austin v. Austin, 968 S.W.2d 319, 321–22 (Tex. 1998) — an unsworn special appearance does not comply with Rule 120a(1) and is ineffectual to challenge in personam jurisdiction.
• Dukatt v. Dukatt, 355 S.W.3d 231, 237 (Tex. App.—Dallas 2011, pet. denied) — when the record shows the special appearance was defective because it was not sworn, the denial must be affirmed.
• Casino Magic Corp. v. King, 43 S.W.3d 14, 18 (Tex. App.—Dallas 2001, pet. denied) (op. on reh’g) — strict compliance with Rule 120a is required.
• Kytel Int’l Grp., Inc. v. Rent-A-Ctr., Inc., 132 S.W.3d 717, 719 (Tex. App.—Dallas 2004, no pet.) — denial of an unsworn special appearance is proper.
• Smith & Nephew PLC v. Hardin, No. 05-23-01065-CV, 2024 WL 3439823 (Tex. App.—Dallas July 17, 2024, pet. denied) (mem. op.) — an attached affidavit verifies a special appearance only if it attests that the facts in the pleading are true and correct.
• W. Sec., Ltd. v. Jaffer, No. 05-24-01492-CV, 2025 WL 2577143 (Tex. App.—Dallas Sept. 5, 2025, no pet.) (mem. op.) — an affidavit or declaration that does not mention or verify the pleading does not cure the defect.
• Innovative Roofing Pros, LLC v. Hinkson, No. 05-25-00202-CV, 2025 WL 2645916 (Tex. App.—Dallas Sept. 15, 2025, no pet.) (mem. op.) — same rule; appellate courts may affirm on any legal theory supported by the record.

Application

The court’s reasoning was straightforward. The appellant presented what, in another posture, might have been a justiciable factual dispute about residency, minimum contacts, and the constitutional limits of Texas jurisdiction over a foreign resident allegedly visiting family in Texas. But the court never reached any of that because Rule 120a imposes a threshold pleading requirement that is mandatory, not aspirational.

The special appearance itself was unsworn. That alone was enough to create a fatal defect under Dawson-Austin and the Dallas line of cases. The appellant’s supplemental filing did not rescue the problem. The daughter’s affidavit discussed some jurisdictional facts, but it did not verify the truth of the allegations in the special appearance. It did not say she had read the special appearance. It did not say the facts set out there were true and correct. And, as the court noted, it did not even clearly satisfy the basic personal-knowledge and truthfulness predicates contemplated by Rule 120a(3). Because strict compliance governs this area, substantial compliance was irrelevant. The filing was dead on arrival.

That approach is especially important for appellate lawyers and trial lawyers handling special appearances in high-stakes family litigation. Texas courts continue to treat Rule 120a as a trapdoor rule: a party either satisfies the procedural prerequisites precisely or forfeits the challenge. Once the court identifies the verification defect in the record, affirmance follows without a merits analysis.

Holding

The Dallas Court of Appeals held that Rule 120a(1) requires a special appearance to be made by sworn motion, and an unsworn special appearance is ineffective to contest personal jurisdiction. Because the appellant’s special appearance and supplemental special appearance were unsworn, the trial court did not err in denying them.

The court further held that an attached affidavit does not cure the defect unless it verifies the special appearance itself by attesting that the facts set out in the pleading are true and correct. The daughter’s affidavit did not do that. It neither referenced nor adopted the special appearance’s allegations, so it failed to convert the pleading into a compliant sworn motion.

Finally, the court held that, where the special appearance is procedurally defective for lack of a sworn motion, the appellate court may affirm denial without reaching the underlying jurisdictional merits. The defendant’s arguments about nonresidency, lack of purposeful availment, absence of general jurisdiction, and fair play and substantial justice were therefore never considered.

Practical Application

For family lawyers, this case is less about tort jurisdiction and more about procedural discipline in multi-state and international domestic litigation. In divorce cases, a nonresident spouse may challenge personal jurisdiction over money judgments, reimbursement claims, fraud-on-the-community claims, enforcement requests, or attorney’s-fees exposure. In SAPCR and modification litigation, a parent may contest the trial court’s personal jurisdiction even when subject-matter jurisdiction under the UCCJEA is separately analyzed. In post-divorce enforcement and turnover disputes, an out-of-state obligor may try to appear specially before contesting contempt-adjacent relief or ancillary money claims. In each setting, an unsworn special appearance can forfeit the fight before it starts.

Strategically, this opinion gives the plaintiff-side family lawyer a clean procedural attack. If opposing counsel files a special appearance without a proper verification, do not be distracted by the merits of minimum contacts. Press the threshold defect. Conversely, if you represent the nonresident spouse or parent, treat Rule 120a compliance as mission-critical. The jurisdictional evidence may be excellent, but if the motion is not sworn, none of it matters.

A few practical implications stand out:

• In divorce litigation, distinguish between contesting status jurisdiction to dissolve the marriage and personal jurisdiction to impose monetary or coercive obligations. A defective special appearance can expose the client to the latter.
• In custody disputes, do not conflate UCCJEA home-state questions with personal jurisdiction objections. They are different doctrines, and Rule 120a still governs the latter.
• In international family cases, where translation issues, remote communications, and affidavit logistics are common, verification defects are especially easy to miss.
• If substituted service was used, do not assume service defects excuse Rule 120a compliance. Preserve each procedural objection correctly and separately.
• Build the verification language into your template practice so the motion itself is expressly sworn or unequivocally verified by affidavit or declaration that adopts the motion’s factual allegations.

Checklists

Special Appearance Compliance Checklist

• Confirm the special appearance is filed before any general appearance or merits-seeking request.
• Caption the filing clearly as a Special Appearance under Rule 120a.
• Ensure the motion is a sworn motion or is accompanied by a compliant verification that expressly verifies the pleading.
• Include language stating that the facts set out in the special appearance are true and correct.
• If using an affidavit or unsworn declaration, make sure the affiant states they have read the special appearance or otherwise expressly adopt its factual allegations.
• Confirm the affidavit or declaration is based on personal knowledge.
• Verify that all exhibits referenced in the motion are attached and properly authenticated where necessary.
• Set the special appearance for hearing without seeking affirmative relief inconsistent with the jurisdictional objection.

Affidavit-Drafting Checklist

• Identify the affiant and establish personal knowledge.
• State expressly that the affiant has read the special appearance.
• State expressly that the facts contained in the special appearance are true and correct.
• Avoid limiting the truthfulness statement to only the affidavit’s contents if the goal is to verify the motion itself.
• Include facts supporting the absence of Texas contacts, including residence, property ownership, business activity, banking, employment, travel patterns, and alleged acts in Texas.
• Confirm dates are consistent with the filing date of the special appearance.
• Review for execution defects, translation issues, and notarial or declaration-formality problems, especially in foreign-country signings.

Plaintiff-Side Response Checklist

• Review the special appearance first for procedural defects before briefing minimum contacts.
• Check whether the motion is actually sworn.
• Check whether any attached affidavit verifies the motion itself, not merely separate facts.
• Compare filing dates to determine whether the affidavit predates or fails to adopt the pleading.
• Object if the affidavit does not show personal knowledge.
• Preserve the strict-compliance argument in writing and at hearing.
• Request denial without merits analysis where Rule 120a is not satisfied.

Family Law Use-Case Checklist

• In divorce, determine whether your client is contesting status jurisdiction, personal jurisdiction, or both.
• In SAPCR/modification cases, separately analyze UCCJEA subject-matter issues and Rule 120a personal-jurisdiction issues.
• In enforcement or property litigation, identify what relief sought requires personal jurisdiction over the nonresident.
• If your client resides abroad, plan early for execution of compliant affidavits or declarations.
• Coordinate with appellate counsel before hearing if the jurisdictional issue may frame the entire case.
• Make a clean record, including a reporter’s record, because family cases often turn on preservation and procedural posture.

Family Law Crossover

This is the kind of civil-procedure ruling that can be weaponized effectively in divorce and custody litigation because it converts a potentially difficult factual jurisdiction dispute into a simple rules-based knockout. If opposing counsel represents a nonresident spouse, parent, paramour, business entity, or third-party custodian and files a defective special appearance, you can force the court to bypass the substantive contacts analysis altogether. That is particularly powerful in cases involving foreign-resident spouses, out-of-state property transfers, Hague-adjacent factual settings, international service complications, or post-divorce enforcement against a party claiming to be beyond Texas reach. On the defense side, the opinion is a warning that sophisticated jurisdiction arguments are worthless if Rule 120a’s verification requirement is mishandled. In practice, this means family litigators should view special appearance drafting as appellate work from day one: exact, verified, and preservation-driven.
