This question has been addressed in 1 Texas court opinion:
COA07 — January 28, 2026
The Seventh Court of Appeals affirmed a trial court's order transferring the exclusive right to designate the children's primary residence from the Mother to the Father. On appeal, the Mother admitted that a material and substantial change in circumstances had occurred but argued that the move was not in the children's best interest. The appellate court analyzed the case using the 'Holley' factors, which assess parental abilities, home stability, and the children's needs. The court ultimately held that because the trial court is in the best position to judge witness credibility and the nuances of the case, and because there was sufficient evidence that the Father could provide a stable environment, the trial court did not abuse its discretion in modifying the custody arrangement.
Litigation Takeaway
“In custody modifications, conceding that a "material and substantial change" has occurred focuses the entire legal battle on the child's "best interest." Because appellate courts give massive deference to trial judges on these issues, litigants must prioritize building a comprehensive record of stability and parental involvement at the trial level, as overcoming an "abuse of discretion" standard on appeal is a high hurdle.”
