When parents disagree about a child’s last name during a Texas divorce, neither parent has the exclusive right to make that decision. Under Texas Family Code § 45.004(a)(1), a court may order a child’s name changed if the change is in the child’s best interest.
A recent Texas appeals court decision examined whether a mother could retain the surname she selected for her child without the father’s input, despite the parents remaining married when the child was born: In re Marriage of Callahan and Lewis, No. 06-25-00104-CV (2026).
