Modifying a Divorce Decree in Texas: When and How It Can Be Done

A Texas divorce decree is a final court order that settles all terms of a divorce, including property division, spousal maintenance, child custody, visitation, and child support. While meant to be permanent, life changes—jobs, health, finances, family needs—often make the original terms unworkable or unfair. Texas law recognizes this and allows modifications, but only under specific rules, standards, and procedures. Below is a complete guide on when you can modify a decree, what can be changed, and exactly how to go through the process.

When Can You Modify a Divorce Decree?

1. Within the First 30 Days: Plenary Power

For 30 days after the judge signs the decree, the court retains plenary power, meaning it can correct, change, or even set aside the order almost freely. You do not need to prove a major change in circumstances—you can ask for adjustments due to errors, omissions, or new information discovered right after the ruling. This is the easiest and fastest time to make changes. Once 30 days pass, the order becomes final, and stricter rules apply.

2. After 30 Days: The Core Legal Standard

Once the 30-day window closes, you may only modify orders if you prove a material and substantial change in circumstances has happened since the original decree was issued. This is the main rule in Texas family law. The change must be significant, not minor or temporary, and something that could not have been reasonably anticipated at the time of divorce.

Common qualifying changes include:

• A large increase or decrease in income, job loss, disability, or retirement
• Relocation that makes the current custody or visitation schedule impossible or impractical
• Serious health issues, new medical needs, or special education requirements for a child
• Evidence that the current arrangement harms the child’s well-being, safety, or development
• Remarriage or long-term cohabitation of the person receiving spousal support
• Repeated violation of the existing order or unsafe living conditions

3. Special Rules for Specific Issues

Child Custody & Visitation

To change conservatorship, primary custody, or visitation:

• You must prove a material/substantial change OR
• The order is at least 3 years old, and modification would serve the child’s best interests
• Courts always prioritize the best interest of the child as the final deciding factor
• If a child is 12 or older, Texas law allows them to share their preference with the judge regarding where they want to live, though it is not binding.

Child Support

You may modify if:

• There has been a material/substantial change, OR
• It has been 3 or more years since the last order, and the change would be at least 20% or $100 more or less per month
• Changes in income, medical costs, or number of children supported are the most common reasons.

Spousal Maintenance

Modification or termination is possible if:

• The receiving spouse remarries or lives with a romantic partner continuously
• Either party’s income or financial situation changes drastically
• The supported person becomes self-sufficient or no longer needs assistance
• Note: You generally cannot modify property division or debt allocation—these are final and almost never changed, except in cases of proven fraud or concealment of assets, which has very short deadlines.

How to Modify a Divorce Decree: Step-by-Step Process

Step 1: Determine What You Want to Change and Why

Clearly list every term you want adjusted and gather all evidence to prove the change in circumstances: pay stubs, medical records, school reports, witness statements, or proof of relocation or unsafe conditions.

Step 2: Try to Reach an Agreement (Uncontested Modification)

If you and your ex-spouse agree on all changes, this is the simplest, cheapest, and fastest path. You will draft a written agreement, both sign it, and present it to the court. Judges almost always approve agreed modifications as long as they are fair and in the child’s best interest.

Step 3: File a Petition to Modify

If you cannot agree, you must file a formal legal document: Petition to Modify the Decree of Divorce or Petition to Modify Parent-Child Relationship (for child-related issues).

• File it in the same county and court that issued your original divorce decree.
• Pay the filing fee (usually $200–$300, varies by county). Most courts require electronic filing via eFileTexas.gov.
• You must include:
  • Case number and names from original divorce
  • Exactly what you want changed
  • Full facts proving the material/substantial change
  • Why the new arrangement is fair and best for children

Step 4: Serve the Other Party

After filing, you must legally notify your ex-spouse. This is called “service of process.” You can use a process server, sheriff, or agree to accept service in writing. They then have a deadline (usually 20 days) to file a response. If they do not respond, you may get a default order in your favor.

Step 5: Attend Mediation (Required in Most Texas Counties)

Before a trial, courts almost always order mediation. A neutral third party helps you both discuss and negotiate. Most modification cases settle here, saving time and money. If you still disagree, the case proceeds to a hearing.

Step 6: Court Hearing

At the hearing, you present all your evidence, documents, and testimony. Your ex will also present their side. The judge reviews everything under Texas law and decides whether to grant the modification. They will issue a new Modified Decree of Divorce, which replaces the old terms and becomes the new enforceable order.

Step 7: Finalize and Enforce

Once signed, the new order is legally binding. Both parties must follow it exactly. If either disobeys, you can file for enforcement or contempt of court.

Key Limitations and Important Facts

• Property and debt division are almost never modified after 30 days, unless you prove fraud or hidden assets within strict deadlines.
• You cannot modify terms just because you are unhappy or want a better deal—you must meet the legal standards.
• There is no limit to how many times you can file, but you must prove a new change each time.
• Legal representation is highly recommended, especially for contested cases, complex finances, or high-conflict custody battles. Mistakes in paperwork or procedure can cause delays or denial.

Modifying a Texas divorce decree is possible, but it follows strict rules designed to balance stability with fairness as life evolves. Whether you need to adjust child support, custody, or spousal support, the success of your request depends entirely on showing clear proof of significant changes and following the correct legal steps. If you and your ex can work together, the process is straightforward; if not, being prepared with strong evidence and proper legal help is your best path to a fair outcome. Always remember: for all child-related orders, the court’s number one priority is what serves the best interests and safety of the children involved.
