CROSSOVER: Texas mandamus: trial court needs Rule 19 good cause to deny pro hac vice admission

In re Tempus Holdings, Inc. d/b/a The Lodge Card Club, and Locus Enterprises, LLC, 04-26-00224-CV, June 10, 2026.

On appeal from 224th Judicial District Court, Bexar County, Texas

Synopsis

A Texas trial court cannot deny a Rule 19 pro hac vice application simply because it is skeptical of the out-of-state lawyer’s involvement or because opposing counsel levels unsupported objections. Under Rule 19(d), denial requires evidence of an enumerated ground or other actual good cause, and mandamus will lie when the record does not support the ruling because the client has no adequate appellate remedy after being deprived of chosen counsel.

Relevance to Family Law

This opinion matters in family law because high-asset divorce, interstate conservatorship, Hague-type custody disputes, business-valuation fights, and trust/property characterization cases often involve non-Texas lawyers who have long-standing relationships with the client or specialized subject-matter knowledge. Tempus Holdings gives family law litigators a strong mandamus framework when a trial court denies pro hac vice admission without record-based good cause, and it also limits the familiar tactical move of opposing admission through insinuations about unauthorized practice, “too many lawyers,” duplication, pricing, or vague claims that the lawyer might become a witness.

Case Summary

Fact Summary

The underlying case was a commercial debt-collection dispute in Bexar County, but the appellate principle is broader. The relators sought admission pro hac vice for Arlan P. Caplan, a Massachusetts lawyer in good standing who filed the required Rule 19 motion. At the hearing on the motion, the opposing party offered argument but no exhibits and had not filed a written response before the hearing. After the court took the matter under advisement, the opponent filed a supplemental brief, relators replied, and the trial court ultimately denied the motion through a bare order that gave no reason.

That absence of stated reasoning mattered. At the later hearing on entry of the order, relators expressly asked the court to identify any evidentiary basis for denial—whether a defect in the application, excessive Texas appearances, prejudice, or conduct justifying denial under Texas law. The court declined to do so and stated only that, having reviewed the case law, it did not think admission was appropriate “in this case.”

The objections asserted by the opposing party centered on three themes: alleged unauthorized practice of law, alleged ethical concerns based on a possible Rule 3.08 witness issue, and generalized “good cause” arguments. Those contentions rested on Caplan’s name appearing on pleadings that were actually signed and filed by Texas counsel, his attendance at a deposition where he did not question the witness, and assertions that he might be a material witness. The opponent also argued that his participation would be duplicative, that he lacked particular experience in the debt-collection niche, and that his hourly rate was unreasonably high.

Issues Decided

• Whether Texas Rule Governing Bar Admission 19(d) permits denial of a pro hac vice application absent evidence of an enumerated ground or other supported good cause.
• Whether an out-of-state attorney’s name appearing on pleadings signed and filed by Texas counsel is evidence of unauthorized practice of law.
• Whether an out-of-state attorney’s attendance at a deposition, without questioning the witness and while accompanied by Texas counsel, establishes unauthorized practice under Texas Government Code section 81.101(a).
• Whether an unsupported assertion that the out-of-state lawyer may be a material witness under Rule 3.08 constitutes good cause to deny pro hac vice admission.
• Whether mandamus is the proper remedy for an erroneous denial of pro hac vice admission.

Rules Applied

Rule 19 of the Rules Governing Admission to the Bar of Texas controlled the dispute. Rule 19(a) authorizes a reputable out-of-state attorney residing outside Texas to seek permission to participate in a particular Texas case by sworn motion. Rule 19(d) gives the trial court discretion to examine the non-resident attorney, but it also cabins that discretion. Denial must rest on one of the rule’s recognized grounds: the attorney is not reputable or will not observe Texas ethical standards, has been appearing in Texas courts on a frequent basis, has engaged in unauthorized practice of law in Texas, or “other good cause” exists.

The court also relied on the Texas Supreme Court’s recent pro hac vice decisions. In In re AutoZoners, LLC, 694 S.W.3d 219 (Tex. 2024), the Court held that the presence of out-of-state lawyers’ names on documents signed and filed by Texas counsel is no evidence of unauthorized practice and does not justify denial of pro hac vice admission. The Fourth Court also cited Verhalen v. Akhtar, 699 S.W.3d 303 (Tex. 2024), which reinforced that mere appearance on a signature block does not prove active participation amounting to unauthorized practice.

For the unauthorized-practice argument, the court referenced Texas Government Code section 81.101(a), which defines the “practice of law.” Although the statutory examples are not exhaustive, the conduct cited by the opponent still had to amount to actual practice in Texas, not mere passive attendance or association with Texas counsel.

On the witness-disqualification point, the court looked to Texas Disciplinary Rule of Professional Conduct 3.08 and the related case law, including Ayres v. Canales, 790 S.W.2d 554 (Tex. 1990), and In re Garza, 373 S.W.3d 115 (Tex. App.—San Antonio 2012, no pet.). Those authorities make clear that dual advocate-witness status does not automatically compel disqualification; the movant must show necessity and actual prejudice.

Finally, the mandamus standard came from In re AutoZoners, LLC, In re AutoNation, Inc., and In re Sanders. The appellate court emphasized that an erroneous order depriving a party of chosen counsel presents the kind of harm that ordinarily lacks an adequate appellate remedy.

Application

The Fourth Court began from the premise that a litigant’s right to select counsel is substantial, and that this principle applies to qualified non-Texas counsel just as it does to Texas-licensed lawyers. From there, the court focused not on whether the trial judge had broad intuition-based discretion, but on whether the record contained evidence supporting any Rule 19(d) ground.

It did not. The court refused to infer a valid basis from a silent order and a record in which the trial court expressly declined to articulate one. That was particularly significant because the relators had invited the court to identify any proper basis—application defect, ethical issue, excessive appearances, prejudice, or unauthorized practice—and the court still issued only a conclusory denial.

On unauthorized practice, the court treated the case as controlled by AutoZoners and Verhalen. Caplan’s name on pleadings did not matter because the pleadings were signed and filed by licensed Texas counsel. His attendance at one deposition also did not move the needle because he asked no questions, was accompanied by Texas counsel, and that conduct did not establish practice of law under section 81.101(a). The court thus rejected the effort to convert peripheral involvement into evidence of unauthorized practice.

The ethical-attacks branch of the opposition fared no better. Caplan’s sworn motion established, without contradiction, that he was licensed and in good standing, admitted in multiple federal courts, approved pro hac vice in numerous states, and not subject to relevant recent discipline or denials. Against that sworn showing, the opponent produced nothing demonstrating that he was not reputable or would fail to comply with Texas ethical standards.

The Rule 3.08 argument was similarly unsupported. The court noted that even if an attorney could theoretically become a witness, disqualification does not follow automatically. The opponent had not shown that Caplan was necessary to prove an essential fact for his own client or that actual prejudice would result from any dual role. In other words, the opponent offered speculation, not evidence.

The remaining “good cause” theories—duplication of counsel, supposed lack of niche experience, and an allegedly excessive billing rate—were dismissed as legally irrelevant under Rule 19. Those are client-side decisions, not recognized bases for excluding otherwise qualified nonresident counsel. Because no valid Rule 19(d) basis appeared in the record, the denial was an abuse of discretion, and mandamus was the proper remedy.

Holding

The court held that a trial court abuses its discretion when it denies a Rule 19 pro hac vice application without evidence supporting a ground authorized by Rule 19(d). A silent order, coupled with a record that contains no proof of an enumerated basis or real “other good cause,” cannot stand.

The court further held that an out-of-state attorney’s name appearing on pleadings signed and filed by Texas counsel is not evidence of unauthorized practice of law. That proposition is now firmly anchored in AutoZoners and reaffirmed through this opinion’s application of that precedent.

The court also held that attendance at a deposition, without questioning the witness and while accompanied by Texas counsel, does not establish unauthorized practice under Texas Government Code section 81.101(a). Passive presence is not the same as managing the proceeding or rendering legal services in a manner prohibited by Texas law.

The court additionally held that an unsupported Rule 3.08 material-witness assertion does not constitute good cause to deny pro hac vice admission. Without proof that the lawyer is necessary to establish an essential fact and without a showing of actual prejudice, the objection is insufficient.

Finally, the court held that mandamus is proper because erroneous denial of pro hac vice admission deprives the party of chosen counsel, and that harm is not adequately remediable by ordinary appeal.

Practical Application

For Texas family law litigators, Tempus Holdings is less about commercial collections than about control of the courtroom when out-of-state counsel is involved. In modern family litigation, parties often retain non-Texas lawyers because of parallel litigation in another state, embedded knowledge of family-office structures, prior representation in premarital or trust matters, or specialized experience with digital assets, executive compensation, or interstate custody disputes. This case gives practitioners a clean framework: if you are opposing pro hac vice admission, you need evidence tied to Rule 19(d), not irritation, suspicion, or rhetoric. If you are sponsoring admission, build a disciplined record and force the opponent and the court to identify a valid basis.

In a divorce case, for example, one side may want longtime non-Texas counsel who negotiated marital agreements, structured family entities, or handled prior litigation affecting characterization and tracing. The opposing side may argue that the lawyer’s historical involvement makes the lawyer a “witness” or that the Texas team is already large enough. Tempus Holdings undermines those objections unless they are supported by concrete proof satisfying Rule 3.08 or another Rule 19(d) ground.

In a SAPCR or relocation case, one party may attempt to frame an out-of-state lawyer’s strategy involvement, attendance at interviews, or name on filings as unauthorized practice. This decision makes clear that courts must examine actual conduct, not labels. Mere association with Texas counsel, appearance on papers signed by Texas counsel, or attendance at proceedings does not itself justify exclusion.

Strategically, the opinion also changes how family lawyers should preserve error. If the trial court denies admission without explanation, ask on the record for the specific Rule 19(d) basis and the evidence supporting it. If the court declines, that silence can become part of the mandamus story. The same is true if the opponent presents only argument and no proof. In pro hac vice fights, the absence of evidence is often the decisive evidence.

Checklists

Checklist for Sponsoring Pro Hac Vice Counsel in Family Cases

• Confirm the nonresident lawyer resides outside Texas and is licensed and in good standing in another jurisdiction.
• File a sworn Rule 19 motion that fully tracks the rule’s required disclosures.
• Include affirmative statements regarding familiarity with and willingness to comply with Texas ethical rules.
• Address disciplinary history, prior denials, and prior pro hac vice appearances with precision.
• Make clear that Texas counsel will sign and file pleadings.
• Avoid creating a record that suggests the nonresident lawyer is independently managing the case in Texas before admission.
• If the lawyer attended any deposition or conference before admission, explain exactly what the lawyer did and did not do.
• Be prepared to rebut any “frequent appearances” argument with specifics rather than general assurances.
• At the hearing, ask the court to identify the precise Rule 19(d) ground at issue.
• If admission is denied, request that the court state its reasons on the record or in the order.

Checklist for Opposing Pro Hac Vice Admission Without Overreaching

• Start with Rule 19(d), not generalized fairness arguments.
• Identify the exact ground you contend applies: lack of reputability, ethical noncompliance, frequent Texas appearances, unauthorized practice, or other good cause.
• Support the objection with actual evidence, not just argument of counsel.
• If asserting unauthorized practice, tie the conduct to Texas Government Code section 81.101 and develop a factual record.
• If asserting frequent appearances, gather admissible proof of repeated Texas-court participation.
• If asserting a Rule 3.08 problem, show why the lawyer is a necessary witness on an essential fact.
• Also show actual prejudice from the alleged advocate-witness conflict.
• Do not rely solely on the lawyer’s name appearing on pleadings signed by Texas counsel.
• Do not assume attendance at a deposition, standing alone, proves unauthorized practice.
• Avoid objections based on duplication of counsel, billing rate, or your view that the lawyer lacks the right niche experience; those are poor Rule 19 arguments.

Checklist for Preserving a Mandamus Record

• Ensure the Rule 19 motion, supporting declaration, and all attachments are filed and included in the clerk’s record.
• Require the opponent to put objections in writing when possible.
• At the hearing, insist that evidentiary objections and offers be clearly recorded by the court reporter.
• Ask whether the opponent has exhibits or sworn testimony supporting the objection.
• Request express findings or, at minimum, an on-the-record explanation of the Rule 19(d) basis for denial.
• If the court enters a bare order, object to the absence of reasons and request clarification.
• Obtain transcripts from all hearings touching the motion, including any later hearing to “enter” the order.
• Frame the prejudice as deprivation of chosen counsel and cite the no-adequate-remedy line of cases.
• Move quickly on mandamus; delay weakens the practical urgency of the complaint.
• Anchor the petition in AutoZoners, Verhalen, and now Tempus Holdings.

Checklist for Family Law-Specific Use

• In complex property cases, document why the non-Texas lawyer has unique historical or transactional knowledge.
• In interstate custody matters, explain the lawyer’s connection to related proceedings in other jurisdictions.
• If the opponent alleges the lawyer is a witness, identify whether the facts can be proved through documents or other witnesses instead.
• Keep Texas counsel visibly in charge of filings, settings, and courtroom management before admission is granted.
• Monitor communications with experts, amicus attorneys, and discovery participants so the record does not get distorted into an unauthorized-practice argument.
• If a hearing is imminent, show concrete case disruption from denial of admission.
• Use this case offensively when the other side attempts to block admission through speculation rather than evidence.
• Use it defensively when your own client is accused of gamesmanship for wanting out-of-state specialty counsel.
• In temporary-orders settings, emphasize that exclusion of chosen counsel can materially affect urgent rulings on conservatorship, support, or property control.
• Consider mandamus promptly where denial affects a major evidentiary hearing, temporary injunction, or trial setting.

Family Law Crossover

This ruling can be weaponized in divorce or custody litigation in two directions. First, if your client needs specialized non-Texas counsel—perhaps because the marital estate includes out-of-state entities, parallel trust litigation, family-office structures, or interstate custody proceedings—Tempus Holdings is a strong shield against exclusion by ambush objections. It tells the trial court that discomfort with nonresident counsel is not enough; the objection must fit Rule 19(d), and it must be supported by evidence.

Second, the opinion can be used as a sword against meritless tactical objections from the other side. Family cases often breed accusations that outside counsel is “really running the case,” “already practicing here,” “duplicative,” “too expensive,” or “going to be a witness.” Tempus Holdings narrows those arguments substantially. If the nonresident lawyer’s name appears on papers signed by Texas counsel, if the lawyer merely attended a deposition, or if the witness theory is undeveloped and prejudice-free, those points should not block admission. For litigators trying cases with national dimensions, that is not a minor procedural point; it is a meaningful protection of client autonomy and litigation strategy.
