Family Code 156.006(b) Significant Impairment Requirement | In re McLean (2026)

In re Gentri Renee McLean, 11-26-00118-CV, May 21, 2026.

On appeal from 318th District Court of Midland County

Synopsis

Section 156.006(b)(1) does not permit a temporary modification changing the parent with the exclusive right to designate the children’s primary residence unless the movant proves the children’s present circumstances would significantly impair their physical health or emotional development. In In re McLean, the Eleventh Court held that denied visitation, school absences, and a parent’s positive cocaine test—without evidence connecting those facts to present significant impairment of the children—are legally insufficient, and mandamus relief is proper.

Relevance to Family Law

This opinion is immediately relevant to Texas custody-modification practice because it reinforces the narrow gatekeeping function of Family Code Section 156.006(b) in temporary-orders hearings. For family-law litigators, the case is a reminder that a trial court may punish visitation interference through available enforcement mechanisms, but it cannot use temporary modification of the primary-residence designation as a substitute sanction absent evidence of present significant impairment to the child. In practice, this sharpens proof requirements in SAPCR modification cases, constrains overbroad temporary-order relief, and provides a strong mandamus framework when trial courts conflate parental misconduct with the statutory impairment standard.

Case Summary

Fact Summary

The parties were divorced in 2025 under an agreed final decree that named Gentri McLean as a joint managing conservator with the exclusive right to designate the primary residence of the parties’ four children. Terry McLean later filed a modification action and sought temporary orders giving him that right.

At the February 2026 temporary-orders hearing, Terry focused largely on Gentri’s interference with his court-ordered possession and access. Gentri admitted she had not complied with visitation provisions, but she explained that the children were afraid of Terry. The evidence also showed that the children were participating in counseling and extracurricular activities, and there was testimony that at least one child’s grades had recently improved.

Terry also raised concerns about Gentri’s alleged cocaine use and aspects of her personal life. Both parties had submitted to hair-follicle drug testing, and both tested positive for cocaine. Gentri denied recent use and testified she had not used in over a year; Terry admitted he had used cocaine in December 2025. Critically, Terry also testified that he had not spoken to the children’s teachers, did not know their grades, did not know they were in counseling, and was unaware of any present danger to their physical health.

The trial court orally rendered temporary orders stripping Gentri of her primary-residence rights and reducing her to possessory conservator status. After an earlier mandamus proceeding in which the Eleventh Court directed the trial court to make the findings required by Section 156.006(b), the trial court withdrew its first ruling and issued a second letter ruling and temporary orders without hearing additional evidence. In the revised ruling, the trial court cited Gentri’s positive cocaine test, an inference that she used drugs while the children were with her, testimony that men spent the night with her, school absences, one occasion when her electricity had been disconnected, and her intentional denial of Terry’s visitation. The April 24 temporary orders appointed Terry temporary sole managing conservator with the exclusive right to designate the children’s primary residence and imposed stringent drug-testing conditions on Gentri before she could resume more substantial possession.

Issues Decided

• Whether Family Code Section 156.006(b)(1) permits a temporary order changing the person with the exclusive right to designate the children’s primary residence without evidence that the children’s present circumstances would significantly impair their physical health or emotional development.
• Whether evidence of denied possession and access, school absences, and a parent’s positive cocaine test, without proof linking those facts to present significant impairment of the children, is legally sufficient under Section 156.006(b)(1).
• Whether mandamus is an appropriate remedy to challenge temporary modification orders entered in a pending SAPCR modification proceeding.

Rules Applied

The court applied Section 156.006(b)(1) of the Texas Family Code, which prohibits a trial court from rendering a temporary order that changes the designation of the person with the exclusive right to determine a child’s primary residence unless the order is in the child’s best interest and is necessary because the child’s present circumstances would significantly impair the child’s physical health or emotional development.

The opinion reiterates that this is a high evidentiary burden. The movant must present evidence of acts or omissions affecting the child that are sufficiently grave to amount to present significant impairment, not merely evidence of parental noncompliance, hostility, or generalized concern. The court relied on authorities emphasizing that violations of a decree or alienation-type conduct, standing alone, do not satisfy the statute’s heightened threshold.

The court also applied settled mandamus principles. Because temporary orders in a modification proceeding are interlocutory and generally not appealable, mandamus is an appropriate vehicle when a trial court clearly abuses its discretion by entering a temporary order that exceeds the limits imposed by Section 156.006(b). The opinion specifically aligns with cases such as In re Sanchez, 228 S.W.3d 214 (Tex. App.—San Antonio 2007, orig. proceeding), and In re Payne, No. 10-11-00402-CV, 2011 WL 6091265 (Tex. App.—Waco Dec. 2, 2011, orig. proceeding) (mem. op.), both of which rejected temporary modifications unsupported by evidence of significant impairment.

Application

The Eleventh Court treated the statutory question as one of legal sufficiency under a tightly cabined temporary-modification standard. The trial court had plainly changed the parent with the exclusive right to designate the children’s primary residence; therefore, Section 156.006(b)(1) applied in full force. That meant the inquiry was not whether Gentri had behaved badly, obstructed access, or triggered understandable judicial frustration. The inquiry was whether the evidence showed that the children’s present circumstances would significantly impair their physical health or emotional development if the existing primary-residence arrangement remained in place pending final trial.

On that record, the court concluded the proof did not clear the statutory bar. The visitation-denial evidence may have supported the trial court’s criticism of Gentri, but it did not itself establish present significant impairment to the children. Likewise, evidence of school absences and the one-time loss of electricity was not developed in a way that demonstrated actual present harm rising to the level the statute requires. The cocaine evidence was similarly incomplete. Both parents tested positive. Terry admitted his own cocaine use. And while the trial court drew inferences that Gentri may have used while the children were in her possession, the evidentiary problem remained the same: there was no proof connecting that circumstance to present significant impairment of the children’s physical health or emotional development.

The court was especially attentive to the absence of child-focused evidence. Terry had not spoken with teachers, did not know the children’s grades, did not know they were in counseling, and was not aware of any present physical danger to them. The appellate court therefore viewed the trial court’s second order as an effort to retrofit Section 156.006 findings onto a record that still lacked the required nexus. The statute demands more than suspicion, moral disapproval, or punitive response to parental disobedience. It requires proof that the children’s current situation is significantly impairing them now.

Holding

The Eleventh Court held that Section 156.006(b)(1) bars a temporary order changing the person with the exclusive right to designate the children’s primary residence unless the evidence shows that the children’s present circumstances would significantly impair their physical health or emotional development. Because the trial court’s order transferred that right from Gentri to Terry, the statute applied and imposed a heightened evidentiary requirement.

The court further held that the evidence cited by the trial court—denied visitation, school absences, a positive cocaine test, testimony regarding overnight male guests, and related concerns—was legally insufficient on this record because it was not tied to proof of present significant impairment to the children. The trial court therefore abused its discretion in entering the temporary modification.

Finally, the court held that mandamus relief was proper because temporary orders in a pending modification case are interlocutory and not subject to direct appeal. The petition was conditionally granted.

Practical Application

For practitioners, McLean is a strong reminder that Section 156.006(b) is not a generalized “best interest” provision. If the requested temporary relief changes the primary-residence designation in substance, the movant must build a child-specific impairment record, not simply a misconduct record against the current primary conservator. Trial judges may be understandably frustrated by denied possession, but frustration with a parent is not evidence that the child’s present circumstances significantly impair the child.

This case is especially useful in three recurring litigation scenarios. First, in denied-access cases, McLean helps separate enforcement from modification. If your client has been wrongfully denied periods of possession, that may justify contempt, enforcement, make-up time, or other remedial relief; it does not automatically justify temporary transfer of primary custody. Second, in drug-use allegations, McLean underscores the need for nexus evidence. A positive test, standing alone, is rarely enough under Section 156.006(b) unless the movant can show how the use is affecting the child in the present tense. Third, in cases involving school attendance or instability in the home, counsel should develop concrete evidence—teacher testimony, counselor testimony, attendance records with context, medical or psychological evidence, and specific proof of impact on the child’s functioning.

For the responding parent, McLean provides a mandamus roadmap. If the trial court changes primary designation on a thin or punitive record, counsel should frame the issue as a statutory overreach, emphasize the absence of evidence of present significant impairment, and move quickly. For the movant, the case is a warning: if you seek temporary primary custody, you must prove more than decree violations, lifestyle concerns, or bad optics.

Checklists

Building a Section 156.006(b) Record for the Movant

• Confirm that the requested temporary relief will, in substance, change the primary-residence designation.
• Plead Section 156.006(b) expressly and track the statutory language.
• Develop evidence focused on the child’s present circumstances, not just the other parent’s misconduct.
• Present testimony from teachers, counselors, therapists, physicians, or other neutral witnesses when available.
• Tie school absences, behavioral issues, emotional dysregulation, or physical neglect directly to current impairment.
• If drug use is alleged, prove timing, frequency, exposure, supervision failures, and actual impact on the child.
• Show why lesser temporary relief would be inadequate short of changing primary designation.
• Request express findings that the child’s present circumstances would significantly impair physical health or emotional development.

Defending Against a Temporary Change of Primary Residence

• Force the movant to identify the exact evidence of present significant impairment.
• Distinguish parental wrongdoing from child-focused statutory impairment.
• Emphasize gaps in the movant’s knowledge of the child’s academics, counseling, medical condition, and daily functioning.
• Highlight evidence that the child is engaged in school, counseling, activities, or otherwise functioning adequately.
• Challenge speculative inferences, especially where drug-test evidence lacks a nexus to the child.
• Argue that possession interference should be addressed through enforcement remedies, not an end-run around Section 156.006(b).
• Request the trial court make specific statutory findings on the record.
• Preserve the mandamus record with transcripts, exhibits, and written temporary orders.

Using Drug-Test Evidence Effectively

• Establish who tested positive, when, and under what testing methodology.
• Avoid assuming that a positive test alone proves use during possession periods.
• Connect any alleged substance use to supervision deficits, exposure, unsafe conditions, or demonstrable child harm.
• Anticipate reciprocal impeachment if both parents have positive results or substance-use history.
• Consider corroborating evidence such as admissions, eyewitness testimony, messages, or incident reports.
• Be prepared to explain why testing conditions imposed by the court are symmetrical or asymmetrical and why that matters.

Responding to Denied Visitation Without Overreaching

• Evaluate whether enforcement, contempt, clarification, or make-up possession is the better procedural vehicle.
• Avoid presenting denied access as if it automatically satisfies significant impairment.
• Develop evidence showing how the denial is presently affecting the child emotionally or developmentally, if that is the theory.
• Separate the parent’s litigation misconduct from the child’s current condition.
• Ask for narrower temporary relief if the evidence does not support a primary-residence change.

Preparing a Mandamus Challenge

• Obtain the reporter’s record from the temporary-orders hearing immediately.
• Compare the trial court’s written findings to the actual evidence admitted.
• Identify whether the order changes primary designation in effect, even if not in label.
• Frame the issue as a failure to comply with Section 156.006(b), not merely a disagreement with factfinding.
• Cite In re McLean, In re Sanchez, and In re Payne for the legal-insufficiency and mandamus framework.
• Explain why no adequate appellate remedy exists because the order is interlocutory.
