Dallas Court Denies Mandamus for Defective Record and Strikes Filing for Unredacted Sensitive Data

New Texas Court of Appeals Opinion - Analyzed for Family Law Attorneys

In re Brittany Hilbert, 05-26-00573-CV, May 04, 2026.

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

Synopsis

The Dallas Court of Appeals denied mandamus relief because the relator did not supply a mandamus record that complied with Texas Rules of Appellate Procedure 52.3 and 52.7. The court also struck the petition and appendix because they disclosed unredacted sensitive data in violation of Rule 9.9, underscoring that even potentially serious conservatorship complaints will not be reached when the filing is procedurally defective.

Relevance to Family Law

This opinion matters directly to Texas family-law litigators because emergency and extraordinary appellate practice often arises in SAPCRs, modification suits, divorce cases involving interim orders, attorney’s-fee awards, possession restrictions, and constitutional parental-rights arguments. The court’s message is blunt: in custody and conservatorship disputes, appellate courts will not rescue a poorly assembled mandamus record, and they will enforce redaction rules even when the underlying issues involve parental presumption, best interest, or final-order defects. For practitioners handling fast-moving family cases, the opinion is a reminder that procedural discipline is not secondary to merits presentation—it is the gateway to merits review.

Case Summary

Fact Summary

The relator, proceeding pro se, filed a petition for writ of mandamus arising from a conservatorship-related matter pending in the 469th Judicial District Court in Collin County. She asked the Dallas Court of Appeals to direct the trial court to vacate its final order, an attorney’s-fee award, and any interim conservatorship or possession provisions, arguing that the rulings were inconsistent with the constitutional parental presumption and the required best-interest analysis.

But the petition arrived with fundamental record problems. The relator filed a notice acknowledging that her appendix did not contain the challenged final order or a transcript of the relevant proceedings. The documents she did provide were also not properly authenticated under the mandamus rules because they were neither certified copies from the clerk nor properly sworn copies supported by an affidavit or unsworn declaration establishing, based on personal knowledge, that the attached documents were true and correct copies of the originals. Compounding those defects, the petition and appendix disclosed unredacted sensitive data.

Those omissions and defects controlled the outcome. Because the court could not confirm the operative order, review what occurred in the hearing below, or rely on a compliant record, it declined to reach the requested mandamus relief.

Issues Decided

Rules Applied

The court relied on the familiar principle that the relator bears the burden to present a record sufficient to establish entitlement to mandamus relief. It cited Walker v. Packer, 827 S.W.2d 833, 837 (Tex. 1992) (orig. proceeding), for that foundational proposition.

The court then applied Texas Rules of Appellate Procedure 52.3(l)(1)(B) and 52.7(a), which require a relator to provide certified or sworn copies of the challenged order and all documents material to the claim for relief. In discussing what qualifies as a compliant record, the court noted that certified copies must come from the appropriate clerk and that sworn copies require an affidavit or unsworn declaration made under penalty of perjury showing personal knowledge that the attached documents are true and correct copies of the originals.

The court also relied on In re Butler, 270 S.W.3d 757, 759 (Tex. App.—Dallas 2008, orig. proceeding), which rejects equivocal verification language such as “to my knowledge” because that phrasing falls short of the personal-knowledge showing required by Rule 52.

On the necessity of including the operative order and relevant transcript, the court cited In re DeMattia, No. 05-21-00460-CV, 2021 WL 5480680, at 1 (Tex. App.—Dallas Nov. 23, 2021, orig. proceeding) (mem. op.), and In re Lowery, No. 05-14-01401-CV, 2014 WL 5862199, at 1 (Tex. App.—Dallas Nov. 13, 2014, orig. proceeding) (mem. op.), both of which reinforce that mandamus relief cannot be evaluated without the order being challenged and, where evidence was received, the reporter’s record.

Finally, the court enforced Texas Rule of Appellate Procedure 9.9, which prohibits disclosure of unredacted sensitive data in appellate filings.

Application

The court treated the mandamus defects as threshold failures, not technicalities that could be overlooked in the interest of reaching the merits. It began with the record-authentication problem. The relator submitted materials, but she did not unequivocally attest that they were true and correct copies of the originals based on personal knowledge. That distinction mattered. Dallas has long insisted that Rule 52 requires certainty, not approximation, and the court expressly invoked Butler to reject verification language that implies something less than personal knowledge. Without certified copies or properly sworn copies, the record was unusable for mandamus purposes.

The court then turned to the more basic omission: the challenged final order and the hearing transcript were absent. That omission was fatal because the relator was asking the appellate court to vacate a final order, an attorney’s-fee award, and conservatorship or possession provisions, yet the court had not been given the operative order itself or a record of the proceedings that produced it. In family-law mandamus practice, where trial courts often make fact-intensive determinations after live testimony, the absence of a reporter’s record can be especially damaging. The court noted that the relator had not shown she sought relief in the trial court relating to obtaining these materials, and it concluded it could not evaluate the merits without them.

The court also addressed the separate Rule 9.9 violation. Rather than merely noting the problem, it struck the petition, including the appendix, for disclosing unredacted sensitive data. That remedy is significant for practitioners: confidentiality failures in family cases—where filings often contain children’s identifying information, birth dates, financial account data, and other protected material—can derail the proceeding independently of any merits issue.

Holding

The court first held that the relator failed to establish entitlement to mandamus relief because she did not provide a properly certified or sworn record. The record submitted did not satisfy Rules 52.3 and 52.7 because the supporting statement did not unequivocally establish, based on personal knowledge, that the attached documents were true and correct copies of the originals.

The court separately held that mandamus relief was unavailable because the relator did not include the challenged final order or the relevant hearing transcript. Those materials were necessary to evaluate the complaints directed at the final order, attorney’s fees, and conservatorship and possession provisions, and without them the court could not reach the merits.

The court further held that the petition and appendix should be struck for disclosing unredacted sensitive data in violation of Rule 9.9. Thus, the proceeding failed on both record-sufficiency grounds and confidentiality-compliance grounds.

Practical Application

For family-law litigators, this case is a practical warning about appellate hygiene in original proceedings. In conservatorship fights, it is common to seek mandamus over temporary orders, jurisdictional rulings, compelled child interviews, discovery sanctions, attorney disqualification, fee awards, or rulings that allegedly impair parental rights. But the urgency of the relief sought does not relax Rule 52. If the petition attacks a final SAPCR order, a divorce decree with conservatorship provisions, or a fee ruling tied to a custody dispute, the petition must include the operative order, every material filing, and the reporter’s record from any hearing where evidence or argument informs the complained-of ruling.

The opinion also has immediate implications for post-trial family litigation. If counsel intends to challenge a final conservatorship ruling or ancillary fee award by mandamus—whether correctly or as part of a broader strategic posture—counsel must first ensure that the clerk’s record and reporter’s record can be assembled in certified or properly sworn form. Filing first and attempting to patch the record later is risky, particularly in Dallas.

Equally important, Rule 9.9 compliance should be treated as a mandatory filing protocol in every family case. SAPCR, divorce, and modification records routinely contain minor children’s identifying information, medical references, school information, and financial-account data. A rushed filing that reproduces trial-court materials without appellate redaction can result in the filing being struck, delaying relief and potentially exposing counsel and client to unnecessary complications.
