Can a Narcissistic Ex Force You Back to Court to Modify a Custody Order in Texas?

 Posted on June 28, 2026 in Child Custody

A narcissistic ex can file to modify a custody order, and some do it more than once. For anyone who survived a hard divorce, getting served with another filing from the same person can feel defeating. Texas law sets a clear standard for what counts as a valid reason for an order modification, and courts are not required to grant every petition.

If you are facing an order modification in 2026, a Fort Worth, TX child custody attorney can help you figure out whether a filing has legal merit.

What Texas Law Requires to Modify a Child Custody Order

Texas Family Code Section 156.101 sets the standard for changing custody, visitation, or conservatorship orders. The parent filing must show a material and substantial change in circumstances that occurred after the current order or settlement agreement was signed. Courts also require that any proposed change serve the best interest of the child.

Changes courts generally accept include a parent moving far away, a major shift in work schedules, a new safety concern in the child's home, or a significant change in the child's needs. Minor disagreements, a new relationship, or a dislike of the current schedule do not, on their own, clear the bar.

Why Would a Narcissistic Ex Keep Filing to Modify Custody?

Most co-parents file to modify a custody order because something real has changed in their lives. For a narcissistic ex, the motivation is often different. According to a national study of 34,653 adults published in the Journal of Clinical Psychiatry, about six percent of people in the United States meet the criteria for narcissistic personality disorder over their lifetime. When a narcissistic person uses conflict to control an ex, repeated filings may become a way to drain the other parent financially and keep the fight going.

Common narcissistic tactics include filing without new evidence, turning small parenting disputes into claimed emergencies, and timing filings around good news in the other parent's life. A petition does require some initial paperwork, and that alone can force the other parent to hire an attorney and spend money responding, even when the claim is unlikely to win.

What "Material and Substantial Change" Means in a Texas Courtroom

Texas Family Code Section 156.401 does not specify exactly what constitutes a material and substantial change.

Courts decide cases on a case-by-case basis, but a few rules come up consistently:

• The change must have happened after the original order was signed. A parent cannot file based on facts that the court already considered when the decree was issued.
• The change has to affect the child's life in a real way. A parenting schedule that feels inconvenient, or a co-parent who makes different day-to-day choices, will not be enough.
• Courts look at the full picture, not a single incident. One argument or one bad weekend rarely justifies a modification. A consistent, documented pattern is what moves courts to act.

If your ex files and cannot meet this standard, the court may deny the petition before a full hearing is ever scheduled.

How to Respond to a Bad Faith Custody Modification Petition in Texas?

When a petition to modify custody is filed, the existing order stays in place until a judge signs a new one. The responding parent is formally served and has the right to contest the modification. Under Texas law, the filing parent must provide at least 45 days' notice before a final hearing is scheduled. That window gives the responding parent time to retain an attorney, gather documentation, and prepare a response.

At the hearing, both sides present evidence and arguments. The filing parent has to show the court that a material and substantial change has occurred. If they cannot meet that burden, the judge can deny the petition. In cases where the filing appears designed to harass rather than address a genuine change, under Texas Family Code Section 156.005, your attorney can ask the court to order the filing parent to pay reasonable attorney’s fees, court costs, and expenses.
