Modifying Custody, Possession, and Support Orders in Texas

A custody order reflects a family at one moment in time, but families change. Children grow, parents move, jobs shift, and new concerns arise. Texas lets custody, possession, and support orders be modified, but not casually: you generally have to show that circumstances have materially and substantially changed, and that the change you want serves the child. This page explains the standard, the special rules that protect stability, and what kinds of changes actually qualify.

Unhappy with the order is not the same as entitled to change it

Modification requires a genuine, material change in circumstances since the last order, plus best interest. Courts protect the stability of existing orders, so a strong modification case is built on real, documented change. A parent who files a frivolous, baseless modification case may be required to pay the attorney’s fees of the responding parent. We have obtained tens of thousands of dollars in judgment against parents who brought frivolous suits against our clients, which is why we carefully vet cases before allowing them to proceed to litigation.

The Core Standard

To modify a conservatorship or possession order, you generally must prove two things: that the circumstances of the child, a parent, or a conservator have materially and substantially changed since the order was rendered, and that the modification is in the child’s best interest. Both are required. A real change with no benefit to the child will not succeed, and a change a parent considers beneficial will not succeed without a genuine change in circumstances. The best-interest standard governs the second half of the test just as it governs the original order.

What Qualifies as a Material and Substantial Change

Whether a change crosses the threshold is fact-specific, but recognized examples include:

  • A parent’s relocation, or a planned move that affects the schedule.
  • A significant change in a parent’s work schedule or availability.
  • Remarriage or a meaningful change in the household.
  • A change in the child’s needs as they grow older.
  • A parent’s substance abuse, instability, or family violence.
  • A parent repeatedly interfering with the other’s access.

Safety-related changes, such as evidence of abuse or a dangerous living situation, carry particular weight and can support not only a modification but emergency relief.

The One-Year Rule for Changing Primary Custody

Texas adds a protective hurdle when a parent seeks to change who has the exclusive right to designate the child’s primary residence within one year of the existing order. In that window, the request must be accompanied by an affidavit setting out facts showing serious circumstances, such as that the child’s present environment may endanger the child’s physical health or significantly impair emotional development, or that the parent with primary residence has agreed to or is voluntarily relinquishing primary care. This rule exists to protect children from being uprooted repeatedly. After the first year, the ordinary material-and-substantial-change standard applies.

Modifying Child Support

Support orders can also be modified. The same material-and-substantial-change standard applies, and Texas provides an additional path: support can be revisited when a set period has passed since the last order and the amount under the current guidelines would differ from the existing order by a threshold amount or percentage. A change in either parent’s income, the child’s needs, or the possession arrangement can all support a support modification.

Agreed Modifications

Not every modification is a fight. When both parents agree that a change makes sense, they can present an agreed modification for the court to approve, which is faster, cheaper, and less stressful than litigation. As with the original order, an agreed change is often reached through negotiation or mediation, then submitted for the court’s approval.

Frequently Asked Questions

Generally you must show a material and substantial change in circumstances since the last order, and that the requested change is in the child’s best interest. The change can involve the child, a parent, or the conservators. Without a real change, a court will not simply revisit a final order because a parent is unhappy with it.

Examples include a parent’s relocation, a significant change in work schedule, remarriage, a change in the child’s needs, a parent’s substance abuse or instability, or family violence. A child growing older and the existing schedule no longer fitting can also qualify. Whether a given change is “material and substantial” is fact-specific.

There is a heightened standard for changing the parent with the exclusive right to designate the primary residence within the first year after the order, requiring an affidavit showing serious circumstances, such as the child’s present environment endangering their physical health or emotional development. After a year, the ordinary material-and-substantial-change standard applies.

Yes. Child support can be modified when there has been a material and substantial change, or under a separate rule when enough time has passed and the guideline amount would differ meaningfully from the current order. The base custody framework and the support guidelines both feed into a support modification.
