Child Support Modification in Texas: When and How to Change Your Order

Life changes. Jobs change, incomes fluctuate, children’s needs evolve, and the child support order that made sense three years ago may no longer reflect current circumstances. Texas law recognizes this reality by allowing parents to modify child support orders when circumstances warrant a change.

Whether you’re the parent paying support who has experienced a significant income reduction, or the parent receiving support whose child’s needs have increased, understanding the modification process helps you take appropriate action. At Griffin & Cain, Attorneys at Law, our Conroe child support attorneys help families throughout Montgomery County, Walker County, and the Houston area navigate the modification process.

When Can You Modify Child Support in Texas?

Texas Family Code Section 156.401 establishes when courts can modify child support orders. You may be eligible to modify if:

Option 1: Material and Substantial Change

The circumstances of the child or a person affected by the order have materially and substantially changed since the last order. Examples include:

• Significant increase or decrease in either parent’s income
• Job loss or change in employment
• Changes in the child’s needs (medical, educational, etc.)
• Changes in health insurance costs or availability
• Changes in custody or possession arrangements
• One parent receiving government benefits
• Birth of additional children (to either parent)

Option 2: Three Years Plus Guideline Change

Alternatively, you can modify if:

• It has been at least three years since the order was signed or last modified, AND
• The monthly support amount under the guidelines differs from the current order by either 20% or $100

This provision allows modification even without dramatic life changes, simply based on the passage of time and changes in income.

The 2025 Child Support Cap Increase: A New Basis for Modification

In September 2025, Texas increased the child support cap from $9,200 to $11,700 in monthly net resources—a 27% increase. This legislative change creates potential grounds for modification for many families.

Who Benefits from the New Cap?

Parents receiving support may benefit if:

• The paying parent earns more than $9,200 per month in net resources
• The current order was calculated using the old $9,200 cap
• Recalculating with the new $11,700 cap would increase support

Example Scenario

If a noncustodial parent earns $15,000 per month in net resources and has one child:

• Under old cap ($9,200): 20% × $9,200 = $1,840/month
• Under new cap ($11,700): 20% × $11,700 = $2,340/month
• Potential increase: $500/month ($6,000/year)

The Child Support Modification Process

Step 1: Evaluate Your Situation

Before filing, honestly assess whether modification makes sense:

• Do you meet one of the eligibility requirements?
• What outcome are you seeking?
• Can you document the changed circumstances?
• Will the other parent likely agree or contest?

Step 2: Gather Documentation

Collect evidence supporting your modification request:

• Recent pay stubs (last 3-6 months)
• Tax returns (last 2-3 years)
• W-2s and 1099s
• Proof of changed employment status
• Documentation of child’s expenses
• Medical bills or special needs documentation
• Health insurance information
• Daycare or childcare expenses

Step 3: Attempt Agreement

If possible, try to reach an agreement with the other parent. An agreed modification is:

• Faster than a contested case
• Less expensive
• Less stressful for everyone, especially children
• Still requires court approval to become enforceable

Note: Private agreements without court approval are not enforceable. Even if you agree, you need a court order reflecting the new terms.

Step 4: File the Petition to Modify

If agreement isn’t possible, file a Petition to Modify in the court that issued the original order. In Montgomery County, this typically means filing with the District Clerk. The petition must:

• Identify the original order being modified
• State the grounds for modification
• Describe the changes you’re requesting
• Provide required financial information

Step 5: Serve the Other Parent

The other parent must be formally notified of the modification request and given an opportunity to respond.

Step 6: Discovery and Disclosure

Both parties exchange financial information. This includes income documentation, expense records, and other relevant financial data. Full disclosure is required—hiding income or assets can have serious consequences.

Step 7: Mediation (Often Required)

Montgomery County courts typically require mediation before trial. Many cases settle at mediation, saving time and money.

Step 8: Hearing or Trial

If mediation doesn’t resolve the case, a hearing is scheduled. The judge will hear evidence and decide whether modification is appropriate and what the new support amount should be.

What Counts as Income for Child Support?

Texas defines “net resources” broadly. Income includes:

• Wages, salary, and commissions
• Overtime pay
• Tips and bonuses
• Self-employment income
• Interest, dividends, and royalties
• Rental income
• Retirement and pension income
• Trust income
• Social Security benefits (except SSI)
• Unemployment benefits
• Disability benefits
• Gifts and prizes (in some circumstances)

Certain deductions reduce net resources:

• Federal income taxes
• Social Security taxes
• Union dues
• Health insurance for the child
• Child support for other children from prior relationships

Can Support Be Modified Retroactively?

Generally, modifications take effect from the date of filing, not before. This means:

• If you need more support, file as soon as circumstances warrant—waiting costs money
• If you need a reduction, file immediately when circumstances change—delays increase your arrears

Courts have very limited authority to modify support retroactively. Don’t wait to file, hoping the court will backdate the modification.

Modifying Support When You’ve Lost Your Job

Job loss is a common reason parents seek modification. If you’ve lost your job:

• File for modification immediately: Don’t wait until you’re behind on payments
• Document your job search: Courts expect you to actively seek employment
• Don’t voluntarily reduce income: Quitting a job or taking a lower-paying position by choice may not justify reduced support
• Continue paying what you can: Showing good faith effort matters

Courts may “impute” income to a parent who is voluntarily unemployed or underemployed—meaning they calculate support based on what you could earn, not what you actually earn.

What If the Other Parent Won’t Comply?

If the other parent isn’t paying the ordered support, modification isn’t the right remedy—enforcement is. Enforcement remedies include:

• Wage withholding
• License suspensions
• Tax refund interception
• Contempt of court (possible jail time)
• Liens on property

Frequently Asked Questions

Can I stop paying child support if I lose my job?

No. You must continue paying the ordered amount until a court modifies the order. Failure to pay results in arrears, which continue to accrue interest. File for modification immediately when circumstances change.

Can child support be modified if my ex got a raise?

Possibly. If the other parent’s income has increased significantly and the children have needs that aren’t being met, this may support modification. The 2025 cap increase also creates potential grounds for modification.

How long does modification take?

An agreed modification can be completed in 4-8 weeks. Contested modifications typically take 3-6 months, sometimes longer if trial is required.

Can I modify support and custody at the same time?

Yes. If circumstances have changed significantly, you may seek modification of both support and custody/possession arrangements.

What if we agree to change support informally?

Informal agreements are not enforceable. The other parent could later pursue you for the full amount under the court order, plus interest. Always get modifications court-approved.
