In re Megan Leigh Burch, 14-26-00358-CV, April 15, 2026.
On appeal from 300th District Court, Brazoria County, Texas
Synopsis
The Fourteenth Court of Appeals denied mandamus relief where the relator sought to overturn a trial-court order denying her motion to exclude an expert witness and to narrow the scope of a child custody evaluation. The court’s short memorandum opinion makes the practical point clear: absent a record and showing establishing a clear abuse of discretion and no adequate appellate remedy, discovery- and expert-related complaints in SAPCR litigation will not support extraordinary relief.
Relevance to Family Law
This opinion is directly relevant to custody litigation, especially modification suits and high-conflict conservatorship disputes in which one side challenges a court-appointed or retained evaluator, mental-health expert, or other opinion witness. For Texas family litigators, the case underscores a recurring reality: attempts to use mandamus to police the scope of child custody evaluations or to strike experts midstream face a steep burden, and the better practice is to build a precise record in the trial court tied to the Family Code, expert reliability principles, and concrete harm that cannot be cured by ordinary appeal.
Case Summary
Fact Summary
The relator, Megan Leigh Burch, filed an original proceeding in the Fourteenth Court of Appeals arising from a family-law case pending in the 300th District Court of Brazoria County. She asked the court of appeals to compel the trial court to vacate a March 17, 2026 order denying her motion to exclude an expert witness. She also sought an order directing the trial court to modify an earlier amended order for child custody evaluation, signed June 5, 2025, so as to limit the evaluation’s scope.
The memorandum opinion is notably brief and does not elaborate on the underlying dispute, the identity of the expert, the precise grounds for exclusion, or the particular ways in which the relator contended the child custody evaluation was overbroad. What the opinion does reveal is that the relator attempted to obtain extraordinary appellate intervention in two related areas that frequently arise in SAPCR practice: expert admissibility and the breadth of a custody evaluation. The court rejected both requests, concluding that the relator had not carried the burden required for mandamus relief.
Issues Decided
- Whether the relator established entitlement to mandamus relief compelling the trial court to vacate its order denying her motion to exclude an expert witness.
- Whether the relator established entitlement to mandamus relief compelling the trial court to modify its amended order for child custody evaluation to limit the scope of the evaluation.
Rules Applied
Although the court did not set out a detailed legal analysis, the opinion necessarily rests on standard Texas mandamus principles:
- Mandamus relief is available only when the relator shows a clear abuse of discretion by the trial court and the absence of an adequate remedy by appeal.
- The relator bears the burden to provide a sufficient record and legal showing establishing entitlement to extraordinary relief.
- Trial courts are generally afforded substantial discretion in managing pretrial matters, including evidentiary rulings, expert challenges, and the conduct and scope of evaluations in family-law proceedings.
- In family cases, complaints concerning discovery, procedure, expert testimony, and evaluation parameters often do not justify mandamus unless the complained-of ruling causes irremediable harm that cannot be addressed through a conventional appeal.
Because the opinion is a short memorandum disposition, it does not cite particular statutes or precedents. Even so, practitioners should read it against the backdrop of Texas Rule of Appellate Procedure 52 governing original proceedings, the well-settled abuse-of-discretion and inadequate-appellate-remedy framework used in mandamus practice, and the Family Code provisions authorizing child custody evaluations and broad trial-court case management in SAPCRs.
Application
The court’s application was concise but decisive. The relator asked the appellate court to intervene in two trial-management decisions: first, the refusal to exclude an expert witness; second, the refusal to narrow a child custody evaluation previously ordered by the trial court. In both respects, the court of appeals concluded that the relator had not demonstrated the exceptional circumstances necessary for mandamus relief.
That conclusion is important because it reflects the appellate court’s reluctance to second-guess interlocutory family-court management decisions absent a developed record showing both a clear departure from governing law and a harm that cannot be repaired later. Expert-exclusion disputes, even when important, are ordinarily reviewed through the normal appellate process after final judgment unless the ruling compromises a protected interest in a way that ordinary appeal cannot remedy. The same is true for disputes over the scope of a custody evaluation. Unless the relator can show that the order exceeds the court’s authority, intrudes on a legally protected interest in a way that cannot be undone, or otherwise creates irreparable prejudice, mandamus remains unlikely.
The opinion also highlights a structural problem that often undermines mandamus petitions in family cases: relators frequently frame the trial court’s ruling as urgent and harmful, but fail to present the appellate court with enough legal and factual material to establish why ordinary appeal is inadequate. The Fourth and Fourteenth Courts alike routinely require a disciplined showing, not just disagreement with the ruling. Here, the relator did not make that showing.
Holding
The Fourteenth Court of Appeals held that the relator failed to demonstrate entitlement to mandamus relief as to the trial court’s March 17, 2026 order denying her motion to exclude an expert witness. As a result, the court denied the request to compel the trial court to vacate that order.
The court also held that the relator failed to demonstrate entitlement to mandamus relief regarding her request to modify the June 5, 2025 amended order for child custody evaluation in order to limit the scope of the evaluation. Accordingly, the court denied that request as well and denied the petition for writ of mandamus in its entirety.
Practical Application
For family litigators, the strategic takeaway is not merely that mandamus was denied, but why these disputes so often fail in the mandamus posture. If you are challenging a custody evaluator, a psychological expert, or a broad evaluation protocol, you should assume the court of appeals will treat the trial court’s ruling as discretionary unless you can anchor your challenge to a specific legal limit and show non-curable harm. General complaints that the evaluator is biased, the expert is unreliable, or the evaluation is too broad are rarely enough on their own.
In divorce and SAPCR litigation, this issue most often arises in at least four settings:
- A party seeks to exclude a custody evaluator or mental-health expert before temporary-orders, enforcement, modification, or final trial.
- A party challenges the scope of interviews, collateral contacts, psychological testing, records review, or home-study components of a custody evaluation.
- A party contends the evaluation invades privileged matters, exceeds the needs of the case, or functions as a discovery end-run.
- A party seeks emergency appellate intervention because the evaluation process itself is already underway and may affect settlement leverage, temporary rulings, or final conservatorship determinations.
The lesson from In re Burch is that the mandamus vehicle should be reserved for the unusual case. In the ordinary case, the stronger approach is to preserve objections meticulously, request narrowing provisions and protective measures in the trial court, secure express rulings, and create a record showing exactly how the complained-of order exceeds lawful discretion. If the concern is confidentiality, privilege, or scope, propose specific guardrails rather than asking only for wholesale exclusion. If the concern is expert methodology, tie the objection to admissibility standards and the concrete role the expert will play in the litigation.
Practitioners should also think ahead about remedy. The appellate question is not whether the trial court may have been wrong; it is whether waiting for appeal is inadequate. In custody disputes, that may require a showing that the evaluation or expert process will cause disclosure, intrusion, or prejudice that cannot later be unwound. Without that showing, mandamus is typically a long shot.
Checklists
Building a Mandamus-Ready Record in a Custody-Evaluation Dispute
- Obtain the signed order appointing or authorizing the child custody evaluation.
- Identify the precise provisions you contend are overbroad, unauthorized, or unsupported.
- File written objections or a motion to modify that targets the challenged provisions line by line.
- Support the motion with evidence, not just argument, including affidavits, records, transcripts, or expert materials if available.
- Request a hearing and obtain a clear ruling on each objection.
- Make sure the mandamus record includes the operative pleadings, motions, responses, exhibits, and hearing transcript.
- Frame the complaint around both prongs of mandamus: abuse of discretion and no adequate appellate remedy.
Challenging an Expert Witness in a Texas Family Case
- Identify whether the expert is court-appointed, retained, or functioning in a hybrid role.
- State the legal basis for exclusion with specificity: qualification, reliability, relevance, scope, methodology, bias, or violation of the appointment order.
- Request a reliability hearing where appropriate.
- Distinguish between objections to admissibility and complaints about weight or credibility.
- Develop evidence showing why the defect is material to the expert’s anticipated opinions.
- Obtain an express ruling and, if necessary, request findings or clarifications in the record.
- Consider whether a narrower remedy—limiting opinions, restricting testimony, or revising the appointment order—will be more attainable than complete exclusion.
Limiting the Scope of a Child Custody Evaluation
- Review the Family Code basis for the evaluation and compare it to the terms of the order.
- Object to unnecessary collateral contacts, excessive records requests, duplicative testing, or matters beyond the conservatorship issues in dispute.
- Raise privilege, privacy, and proportionality concerns with specificity.
- Propose protective language, including confidentiality restrictions, time limits, subject-matter limits, and sequencing requirements.
- Ask the trial court to define the evaluator’s authority in concrete terms rather than leaving broad discretion unstated.
- Preserve any complaint that the evaluation is being used to obtain improper discovery or to influence temporary rulings unfairly.
- Create a record of why the breadth of the evaluation will cause harm that cannot be cured after judgment.
Avoiding the Relator’s Problem on Mandamus
- Do not assume the court of appeals will infer irreparable harm from the nature of the dispute.
- Do not rely on generalized assertions that an expert is unfair or an evaluation is intrusive.
- Do not file mandamus without a complete Rule 52 record.
- Do not conflate a potentially erroneous ruling with a clear abuse of discretion.
- Do not ignore the adequate-remedy-by-appeal requirement.
- Do not wait too long to challenge an order if the complained-of process is already unfolding.
- Do not seek only all-or-nothing relief when a narrowed request may better expose the trial court’s abuse of discretion.
