Dallas Court of Appeals Denies Mandamus for Noncompliance With Rule 52 and Strikes Filing for Unredacted Sensitive Data

In re Brittany Hilbert, 05-26-00549-CV, April 23, 2026.

On appeal from 469th Judicial District Court, Collin County, Texas

Synopsis

The Dallas Court of Appeals denied mandamus relief because the relator’s filing did not satisfy multiple mandatory requirements of Texas Rule of Appellate Procedure 52, including the certification and record requirements that are prerequisites to mandamus review. The court also struck the petition and appendix because they disclosed unredacted sensitive data in violation of Rule 9.9, underscoring that procedural noncompliance alone can end an original proceeding before the court ever reaches the merits.

Relevance to Family Law

For Texas family-law litigators, this opinion is a useful reminder that emergency appellate practice in custody, conservatorship, possession, support, fee, and property disputes is unforgiving. In family cases, lawyers often pursue mandamus on compressed timelines involving temporary orders, enforcement proceedings, discovery disputes, ex parte presentations, attorney-fee awards, and restrictions affecting parent-child contact. In re Brittany Hilbert shows that even when the underlying complaint invokes due process, parental presumptions, or best-interest concerns, the court will not reach those issues unless the petition strictly complies with Rule 52 and all family-law records are properly redacted under Rule 9.9. In other words, appellate procedure is often outcome-determinative in custody litigation.

Case Summary

Fact Summary

This original proceeding arose out of a conservatorship-related matter pending in the 469th Judicial District Court in Collin County. Acting pro se, the relator sought mandamus relief directing the court of appeals to require the trial court to vacate any order entered after April 17, 2026, to the extent the order was allegedly entered without due process or based on materials submitted outside her presence. She also sought relief from an attorney-fee award and from interim conservatorship or possession provisions, invoking the constitutional parental presumption and the required best-interest analysis.

The Fifth Court did not engage the substance of those complaints. Instead, it focused on threshold defects in the mandamus filing itself. The petition failed to comply with several mandatory provisions of Texas Rule of Appellate Procedure 52, and the filing also contained unredacted sensitive data. Those procedural defects controlled the disposition.

Issues Decided

The court decided the following issues:

• Whether the relator was entitled to mandamus relief when the petition did not comply with multiple mandatory requirements of Texas Rule of Appellate Procedure 52.
• Whether the court should consider the petition on the merits despite the absence of required certification and record components.
• Whether the petition and appendix should be struck for disclosure of unredacted sensitive data in violation of Texas Rule of Appellate Procedure 9.9.

Rules Applied

The court relied on the Texas Rules of Appellate Procedure governing original proceedings, especially the mandatory content and filing requirements for mandamus petitions.

• Texas Rule of Appellate Procedure 52.3(c): requires an identity-of-parties-and-counsel section.
• Texas Rule of Appellate Procedure 52.3(f): requires a statement of jurisdiction.
• Texas Rule of Appellate Procedure 52.3(k): requires an appendix containing specified documents.
• Texas Rule of Appellate Procedure 52.3(l)(1)(B): requires a certification that every factual statement in the petition is supported by competent evidence included in the appendix or record.
• Texas Rule of Appellate Procedure 52.7(a): requires a mandamus record, including certified or sworn copies of every material document and any necessary reporter’s record.
• Texas Rule of Appellate Procedure 9.9: requires redaction of sensitive data in filed documents.

The court also cited prior Dallas authority showing that Rule 52 compliance is not aspirational.

• In re Integrity Mktg. Grp., LLC, No. 05-24-00922-CV, 2024 WL 3770377, at *1 (Tex. App.—Dallas Aug. 13, 2024, orig. proceeding) (mem. op.), denying mandamus relief solely because the petition lacked the Rule 52.3 certification.
• In re Butler, 270 S.W.3d 757, 759 (Tex. App.—Dallas 2008, orig. proceeding), denying mandamus relief for lack of a Rule 52.3 certification and the absence of a sworn or certified record.

Application

The Fifth Court treated the defects as dispositive. The relator asked for extraordinary relief affecting trial-court orders, attorney’s fees, and interim conservatorship or possession provisions, but the court first examined whether the filing met the baseline requirements for mandamus review. It concluded that the petition failed to comply with Rule 52 “in numerous respects,” specifically identifying defects under Rules 52.3(c), 52.3(f), 52.3(k), 52.3(l)(1)(B), and 52.7(a).

That mattered because mandamus review depends on a properly assembled procedural vehicle. A court of appeals cannot evaluate whether a trial court clearly abused its discretion, or whether there is an adequate appellate remedy, unless the relator provides a compliant petition, a proper certification, and a sworn or certified record containing the material orders and evidence. The court’s citation to Integrity Marketing and Butler reinforces that the absence of the Rule 52.3 certification or a proper record is independently sufficient to deny relief without reaching the merits.

The court then addressed a separate defect: the filing disclosed unredacted sensitive data. In a family-law proceeding, that problem is especially acute because filings often contain birth dates, names of minors, financial account information, and other protected identifiers. The court therefore not only denied the petition, but also struck the petition and appendix under Rule 9.9. The opinion makes clear that a party can lose both on mandamus sufficiency grounds and on confidentiality grounds in the same order.

Holding

The court held that the relator was not entitled to mandamus relief because the petition failed to comply with multiple mandatory provisions of Texas Rule of Appellate Procedure 52. In particular, the deficiencies included required petition contents, certification, appendix, and mandamus-record components necessary for the court to consider the request for extraordinary relief.

The court also held that the relator’s petition and attached appendix should be struck because they disclosed unredacted sensitive data in violation of Rule 9.9. Thus, even apart from the Rule 52 defects, the filing itself was improper for public filing in its submitted form.

Practical Application

Family-law appellate practice frequently develops under pressure, particularly when trial courts enter temporary conservatorship rulings, possession restrictions, emergency protective measures, sanctions, attorney-fee awards, or orders entered after contested hearings with disputed notice and participation issues. This case is a sharp reminder that counsel should treat mandamus assembly as a discipline separate from merits briefing. A strong due-process argument is useless if the petition lacks the required Rule 52 certification, omits the operative order, fails to include sworn or certified copies of material documents, or neglects a necessary reporter’s record.

The opinion also has direct application to confidentiality management in family cases. Many family files are saturated with Rule 9.9 material. If counsel is rushing to file an emergency mandamus involving children, financial records, medical records, school information, or identifying information, redaction cannot be an afterthought delegated without supervision. The filing team should assume that every appendix tab and every page of the mandamus record may contain sensitive data requiring review. A Rule 9.9 failure does not merely create embarrassment; it can lead to the filing being struck and can delay urgent relief in cases where hours matter.

Strategically, this decision supports three practice points. First, preserve the mandamus record in the trial court before the emergency arises. Second, maintain a standardized Rule 52 template for original proceedings in family cases, including a certification block that tracks Rule 52.3(l)(1)(B). Third, build a redaction protocol specific to family-law filings, particularly for exhibits drawn from SAPCR, divorce, modification, and enforcement proceedings.

Checklists

Mandamus Petition Compliance Review

• Confirm the petition includes the identity of parties and counsel required by Rule 52.3(c).
• Confirm the petition includes a statement of jurisdiction under Rule 52.3(f).
• Confirm the petition contains all other required Rule 52 sections in proper form.
• Include the Rule 52.3(l)(1)(B) certification stating that every factual statement is supported by competent evidence in the appendix or record.
• Verify that the relief requested is stated with precision and tied to identifiable trial-court rulings.
• Make sure the petition identifies the exact order or action challenged and the date it occurred.

Mandamus Record Assembly

• Include a certified or sworn copy of every order material to the claim for relief.
• Include all motions, responses, exhibits, and docket materials necessary to understand the complained-of ruling.
• Include any reporter’s record necessary to show what occurred at the hearing.
• If the complaint involves ex parte submissions or lack of notice, include documents and transcripts establishing that procedural history.
• Check that every record item is authenticated as required by Rule 52.7(a).
• Organize the record so the court can quickly identify the operative ruling and supporting materials.

Family-Law Sensitive Data Redaction

• Review the petition, appendix, and mandamus record for Rule 9.9 material before filing.
• Redact birth dates, minor-identifying information, financial account numbers, driver’s-license numbers, Social Security numbers, and other protected identifiers.
• Review custody evaluations, school records, medical records, and financial documents line by line.
• Confirm that scanned exhibits did not preserve visible unredacted text beneath highlighting or boxes.
• Use sealed filings where authorized and appropriate rather than publicly filing sensitive material unredacted.
• Perform a final PDF review of the exact upload version, not merely the source document.

Emergency Family-Law Mandamus Triage

• Determine whether the complaint concerns a temporary order, fee award, possession restriction, discovery ruling, or due-process issue that may warrant mandamus.
• Identify whether there is a clear abuse of discretion and no adequate appellate remedy.
• Secure signed orders immediately; do not rely on oral rulings or docket-sheet descriptions.
• Order the reporter’s record on an emergency basis if hearing testimony or arguments matter.
• Prepare a chronology of notice, hearing settings, submissions, and trial-court action.
• Conduct a same-day procedural sufficiency audit before filing.

Avoiding the Relator’s Outcome

• Do not assume a court will overlook Rule 52 defects because the client is pro se or the issues are urgent.
• Do not file without the Rule 52 certification.
• Do not rely on unsworn, uncertified attachments when certified or sworn copies are required.
• Do not treat confidential family-law data as a clerical issue; treat it as a merits-affecting filing requirement.
• Do not expect the court to reach constitutional or best-interest arguments if the petition is procedurally defective.
• Do not separate appellate strategy from document-control and redaction workflows.
