Custody Modifications in Texas — When and How to Change a Custody Order

The Legal Standard for Custody Modification in Texas

Texas courts do not modify custody orders simply because a parent is unhappy with the existing arrangement or believes a different arrangement would be better. The law sets a specific threshold that must be met before a court will consider modifying a prior custody order.

Under Tex. Fam. Code §156.101, a court may modify a conservatorship or possession order if:

• The circumstances of the child, a conservator, or another party affected by the order have materially and substantially changed since the order was entered, AND
• The modification is in the best interest of the child

Both elements must be satisfied. A material and substantial change that does not result in a better outcome for the child is insufficient. And a proposed arrangement that would benefit the child is not enough without a qualifying change in circumstances.

Common Grounds for Custody Modification in Texas

The Child’s Preference as Grounds for Modification

Texas Family Code §156.101(a)(2) provides a specific modification pathway based solely on a child’s preference: if a child who is 12 years of age or older files a written statement with the court expressing a preference about which parent should have the right to designate their primary residence, the court must hold a hearing on the modification — without requiring any other showing of changed circumstances.

This is unique to Texas and is an important tool. However, the child’s preference triggers a hearing — it does not automatically result in a modification. The judge will still evaluate whether granting the preference is in the child’s best interest, and will look carefully at whether the preference was influenced by a parent.

Relocation and Geographic Restrictions

Most Texas custody orders include a geographic restriction — a provision limiting the child’s primary residence to a specific county or counties. Common restrictions include Williamson County and contiguous counties, or Travis County and contiguous counties.

When the primary parent wants to move outside the geographic restriction — whether across Texas or to another state — they must either obtain the other parent’s written agreement or seek a court order modifying the geographic restriction.

For the Parent Wanting to Relocate

You must demonstrate that the relocation is in the child’s best interest — not merely convenient for you. Courts consider the reason for the move, the impact on the child’s relationship with the other parent, the proposed new possession schedule, and the overall effect on the child’s stability and wellbeing.

For the Parent Opposing Relocation

You can file a modification seeking to prevent the relocation or, alternatively, seeking to become the primary parent if the other parent relocates. Courts regularly award primary conservatorship to the non-relocating parent when the proposed move would significantly impair the child’s relationship with that parent.

Emergency Custody Modifications — Temporary Restraining Orders

When a child faces an immediate danger — active abuse, a parent’s acute substance abuse crisis, or another threat to the child’s safety — a party can seek an emergency modification through a Temporary Restraining Order (TRO) without prior notice to the other parent (an ex parte order).

To obtain an emergency ex parte order modifying custody, the requesting party must show that the child’s physical health or emotional welfare would be in immediate danger if the other parent is given notice before the order is entered (Tex. Fam. Code §105.001).

An emergency TRO is temporary — typically lasting 14 days. A full temporary orders hearing must be held quickly to determine whether temporary custody changes should remain in effect while the modification case is pending.

The Modification Process — Step by Step

• File a Petition to Modify — filed in the court that entered the original order (Tex. Fam. Code §155.001 controls jurisdiction)
• Service of process — the other parent must be served with the petition
• Temporary orders hearing (if requested) — to establish interim arrangements while the modification case is pending
• Discovery — exchange of financial records, communications, and evidence supporting or opposing the modification
• Mediation — required in most Texas courts before a contested modification goes to trial
• Trial — if mediation fails, the judge hears evidence and enters a final modified order

Defending Against a Custody Modification

If the other parent has filed a modification against you, the most important thing to understand is that the burden of proof is on the party seeking modification. They must prove the material and substantial change. Your job is to demonstrate that no qualifying change has occurred — or that even if it has, the proposed modification is not in the child’s best interest.

Effective defenses include:

• Demonstrating that the alleged change in circumstances is not material or substantial
• Showing that the circumstances the other parent relies on were known or foreseeable at the time of the original order
• Building a strong affirmative record of your parenting — stability, involvement, the child’s thriving in the current arrangement
• Demonstrating that the proposed modification would disrupt the child’s stability rather than improve it
• If false allegations are involved — cooperative investigation combined with affirmative documentation of your positive parenting
