Can a Texas court give custody or decision-making rights to someone other than the biological parent?

This question has been addressed in 2 Texas court opinions:

In the Matter of the Marriage of Gertha Marie Chatman and Kraton Dorrell Chatman and In the Interest of A.M.H. and A.L.H., Children

COA12February 11, 2026

This case involved a custody dispute between a biological father and nonparent intervenors (the maternal aunt and uncle) who had been caring for twin infants. The primary issues were whether the nonparents had legal standing to seek custody and whether the trial court erred in awarding them conservatorship over the fit biological father. The Twelfth Court of Appeals determined that while the nonparents' initial petition was properly struck, their second petition established standing because they had exercised exclusive 'actual care, control, and possession' for at least six months following the mother's departure from the home. However, the court reversed the conservatorship award, holding that under the Texas 'parental presumption,' a nonparent must prove that a parent's appointment would significantly impair the child's physical health or emotional development. The court found that evidence of the father's past drug use and the intervenors' concerns about his 'lifestyle' were insufficient to meet this high evidentiary bar.

Litigation Takeaway

Standing is a jurisdictional threshold that can be cured by the passage of time; a nonparent who fails the six-month residency requirement today may acquire standing through a subsequent filing once the timeframe is met. However, establishing standing does not guarantee custody, as nonparents must overcome the powerful 'parental presumption' with specific evidence of significant impairment to the child, rather than mere 'best interest' comparisons or vague lifestyle grievances.

In the Interest of B.R.H., A Child

COA06February 11, 2026

In this modification case, the Sixth Court of Appeals upheld a trial court's order restricting a mother's visitation to supervised, therapeutic-only access after she unilaterally and unnecessarily admitted her child to a psychiatric facility. The appellate court analyzed the child's best interests under the Texas Family Code, weighing expert testimony from a counselor and an in-chambers interview where the child expressed fear of the mother's medical decision-making. The court held that the trial court did not abuse its discretion in limiting the mother’s access, awarding the father exclusive educational rights, and calculating child support based on the mother’s earning capacity instead of her reported income.

Litigation Takeaway

A parent's unilateral and unwarranted medical or psychiatric decisions can be legally characterized as harmful acts, providing sufficient grounds for a court to restrict that parent to supervised visitation and transfer exclusive decision-making rights to the other parent.
