Modifying Child Support Orders in Texas

Child support orders are set at a point in time. When life changes, including a job loss, a disability, a custody shift, or a child’s changing needs, the original amount can stop making sense. Many parents in San Antonio feel stuck, wondering how they will keep up with payments or, as a support recipient, how they will adequately provide for their child when the current amount no longer reflects reality.

Under Texas law, a path to child support modification exists, but the existing order stays in full force until a family law judge officially changes it. Falling behind on payments while waiting can result in income garnishment, license suspension, or contempt proceedings in the Bexar County court. Acting early gives you more options and better outcomes.

What Are the Legal Grounds to Modify Child Support in Texas?

Under Texas Family Code § 156.401, a court can modify a child support order if there has been a material and substantial change in circumstances affecting the child or a person bound by the order. The change must be meaningful, documented, and ongoing; it cannot simply be temporary or minor. Common grounds for a successful modification include the following:

• Job loss or significant income reduction: A layoff, termination, or reduction in hours that meaningfully lowers the paying parent’s net resources.
• Substantial income increase: If the paying parent’s income has grown significantly, the receiving parent can seek a higher amount.
• New disability: A disability affecting either parent’s capacity to earn income.
• Changed child needs: New medical diagnoses, therapy requirements, or special education costs that the original order did not account for.
• Custody change: A shift in parenting time affects the support calculation.
• Additional legal children: Other children the paying parent is legally obligated to support may reduce available net resources.

Pay stubs, termination letters, medical records, and tax returns all support a modification petition. § 156.401(a)(2) also provides an alternate pathway requiring no proof of change: if three years have passed since the order was last set and the current amount differs from what the Texas guidelines would produce today by at least 20 percent or $100 per month, either parent can seek a modification on that basis alone. 

Can You Modify Child Support Without Going to Court?

Sometimes, but only to a point. If both parents agree on a new amount, you can avoid a contested hearing entirely. Both parents sign the agreed modification, a child support attorney drafts the formal petition, and it gets submitted to the court for a judge’s signature. The existing order stays in place until that signature happens, but agreed-upon modifications move significantly faster than contested ones.

This route works well when both parties are cooperative, and the reason for the change is straightforward. When there is disagreement about the amount, the grounds, or whether a change is warranted at all, the case goes to a hearing before a Bexar County family court judge.

How Does the Child Support Modification Process Work in San Antonio?

Modification cases in San Antonio are handled in the Bexar County district courts. The general process follows these steps:

• File a Petition to Modify: File the Petition to Modify the Parent-Child Relationship in the appropriate Bexar County district court.
• Serve the other parent: The other parent must be formally served with the petition and a citation.
• Exchange financial documentation: Both parties share income information, tax returns, and supporting records.
• Agreed resolution or hearing: Agreed modifications may go directly to a judge for approval; contested cases require a hearing.
• Judge signs the order: The adjusted amount takes effect once the court signs and enters the new order.

One thing that catches parents off guard is that modifications generally do not apply retroactively. The new amount takes effect from the date the petition is filed, not from when your circumstances changed. Our San Antonio child support attorneys at Prince Contreras PLLC can help you assess your options before filing.

How Long Does a Child Support Modification Take in Texas?

An agreed modification can often be finalized within 60 to 90 days of filing. A contested modification can take six months or longer. Either way, the timing of your filing matters, as the adjusted amount generally takes effect from the date you file, and every month you wait is a month the existing order controls.

FAQ: Modifying Child Support in San Antonio, Texas

Can a Child Support Order Be Modified if the Child Moves in With the Paying Parent?

Yes. A significant change in parenting time is a recognized ground for modification under Texas Family Code § 156.401. If the child has moved in with the paying parent on a lasting basis, that shift in custody affects how support is calculated and may warrant a reduction or elimination of the obligation. Filing promptly ensures the adjustment takes effect as soon as possible.

Can I Request a Temporary Child Support Order While My Modification Case Is Pending?

Yes. If your circumstances have changed significantly and the process will take time to resolve, a Texas court can issue a temporary order adjusting the support amount while the case is pending. This can protect you from falling further behind or from receiving inadequate support during the modification process. Our attorneys can advise whether a temporary order makes sense in your situation.

What Happens if a Parent Misses Payments While a Modification Is Pending?

Missed payments accrue as arrears under the existing order, even if a petition has been filed. The court does not forgive them retroactively. Filing promptly and, if needed, requesting a temporary order protects you during the process.

How Is the New Child Support Amount Calculated After Modification?

Texas uses a percentage of the paying parent’s net monthly income under Texas Family Code § 154.125: 20 percent for one child, 25 percent for two, 30 percent for three, 35 percent for four, and 40 percent for five or more. Courts may deviate based on special needs or other factors. The Texas OAG child support calculator provides a starting estimate.

What Happens if the Other Parent Refuses to Agree to a Modification?

You can still file for a contested modification in the Bexar County court. Your lawyer will present your evidence at a hearing, and a judge will determine whether the standard for modification has been met.
