To reduce child support in Texas, you have to qualify under one of two legal grounds, then either file a modification petition in the court that issued your order or request an administrative review through the Office of the Attorney General. You cannot simply start paying less. Every dollar under your existing order keeps coming due as a legal judgment until a judge signs a new one, so the sooner you file, the less you lose.
Do You Qualify for a Modification?
Texas law gives you two separate paths. You only need one.
A Material and Substantial Change in Circumstances
The most common ground is showing that something significant has changed since your current order was signed. The change can involve you, the other parent, or the child.1State of Texas. Texas Family Code FAM 156.401 – Modification of Child Support Situations that typically qualify include:
- An involuntary job loss, layoff, or forced reduction in hours or pay
- Becoming legally responsible for additional children from another relationship
- A meaningful change in the child’s medical costs, insurance coverage, or living arrangements
- A substantial increase in the other parent’s income
The change has to be real and lasting. A single bad month at work or a short gap between jobs usually will not persuade a judge that your financial picture has genuinely shifted.2Texas Law Help. Legal Standards in Custody and Support Modification Cases
The Three-Year Review
Even without a major life event, you can seek a modification if at least three years have passed since the order was signed or last modified, and the amount you would owe under the current guidelines differs from your existing order by at least 20% or $100 per month.1State of Texas. Texas Family Code FAM 156.401 – Modification of Child Support The Attorney General’s office uses the same test when reviewing cases administratively.3Office of the Attorney General. Support Modification Process
To check whether you clear the threshold, you need to run the guideline math on your current income. Texas calculates support as a percentage of your monthly net resources: 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five, with a lower schedule if your net resources fall below $1,000 per month.4State of Texas. Texas Family Code Section 154.125 – Application of Guidelines Net resources include wages, self-employment income, rental income, and most other income you actually receive, minus Social Security taxes, federal and state income taxes, union dues, and the cost of court-ordered health or dental coverage for the child.5State of Texas. Texas Family Code FAM 154.062 – Net Resources If the guideline figure for your current income is meaningfully lower than what you’re paying now, you have grounds to ask for a reduction.
When a Court Will Not Lower Your Payment
If your income dropped because you chose to earn less, the judge can refuse to modify your order and instead calculate support based on what you could be earning. The statute lets the court apply the guidelines to your earning potential rather than your actual income when a parent is intentionally unemployed or underemployed.6State of Texas. Texas Family Code FAM 154.066 – Intentional Unemployment or Underemployment
Quitting a well-paying job for a lower-paying one without a strong reason, turning down overtime you used to work, or voluntarily cutting your hours will draw scrutiny. The other parent’s attorney will argue you engineered the drop to shrink your obligation, and judges hear that argument often. If the court agrees, your modification is denied and the original order stands.
One exception matters: incarceration cannot be treated as intentional unemployment when a court sets or modifies support.6State of Texas. Texas Family Code FAM 154.066 – Intentional Unemployment or Underemployment If you are behind because you were in jail or prison, the court must look at your real circumstances rather than imputing your pre-incarceration wages.
Two Ways to File
Petition the Court Directly
The formal document is a Petition to Modify the Parent-Child Relationship. Texas Law Help maintains a free toolkit with the current form and instructions,7TexasLawHelp.org. Petition to Modify the Parent-Child Relationship and you can also get it from the district clerk in the county where the original order was issued.
You will need your original case number, the court number, and identifying information for both parents and each child covered by the order. The petition must state which legal ground you are relying on and describe the changed circumstances. Pull your supporting documents together before you file:
- Recent pay stubs, a termination letter, or records showing reduced hours or wages
- Two to three years of tax returns to show a sustained income trend, not one bad year
- Birth certificates for any additional children you now support
- Medical records or insurance statements if the child’s health care costs have changed significantly
Most courts also require a financial information sheet or sworn affidavit covering your current income, expenses, assets, and debts. The base statutory clerk’s fee for a modification within an existing family case is $15, but service fees, court costs, and any domestic relations office fees push the real total higher depending on your county.8Texas Judicial Branch. District Court Civil Filing Fees After filing, you must have the other parent formally served through a process server or the sheriff’s office, typically another $75 to $125.
Ask the Attorney General to Review Your Case
You can skip court as a first step and ask the Office of the Attorney General to handle your modification through the Child Support Review Process. The CSRP is an administrative proceeding where a child support officer reviews both parents’ finances and proposes an adjusted amount.9Office of the Attorney General of Texas. Understanding the Legal Process If both parents accept, the agreement goes to the court for approval and becomes binding. If either parent rejects it, the case is forwarded to court for a hearing.
The CSRP is free and well suited to straightforward cases where the income change is clear. It is less useful when the facts are disputed, self-employment income is hard to verify, or the other parent contests whether your income drop was voluntary. The eligibility requirements are the same as for a court-filed modification.3Office of the Attorney General. Support Modification Process
Agreed Orders Move Faster Than Contested Ones
If you and the other parent agree on the new amount, you can sign an agreed modification order and submit it to the judge, who reviews it against the guidelines and the child’s best interest.10Texas Law Help. I Need to Change a Custody, Visitation, or Support Order This is the fastest and cheapest path.
When the other parent disagrees, the case is contested. After service, the court may refer both sides to mediation. If that fails, the case proceeds to a hearing where each parent presents evidence and the judge rules. Expect at least six months from filing to a final modified order, and longer in contested cases with scheduling delays or discovery fights.11Office of the Attorney General. Modification Journey
File the Day Your Circumstances Change
This is the single most expensive mistake parents make. Under federal law, every child support payment becomes a legal judgment the moment it comes due, and no state court can erase support debt that accumulated before you filed.12Office of the Law Revision Counsel. 42 USC 666 – Requirement of Statutorily Prescribed Procedures
The earliest a modification can take effect is the date the other parent is served with your petition. Not the date you lost your job. Not the date you decided to file. The actual service date. Every month between your income drop and that service date, you owe the full original amount. If you cannot pay it, the unpaid balance becomes arrearages that follow you until paid in full. No judge can wipe that slate clean, and bankruptcy will not discharge it.
Lose your job on March 1 and wait until August to file, and you owe five months at the old rate no matter what happened to your paychecks. File as soon as the qualifying change happens.
Keep Paying the Current Order Until a Judge Changes It
While your case is pending, you are legally obligated to pay the full amount under your existing order. Informal side agreements with the other parent do not change what you owe. Even if the other parent verbally agrees to accept less, the original order controls until a judge signs a new one.3Office of the Attorney General. Support Modification Process
Falling behind while you wait is costly. The Attorney General can petition to suspend your driver’s license, professional licenses, and hunting and fishing permits once you owe three or more months of overdue support.13Office of the Attorney General. License Suspension A judge can also hold you in contempt, which carries potential jail time, and the federal government can deny or revoke your passport for arrearages over $2,500.
If your income has truly collapsed and you cannot pay in full, pay whatever you can. Partial payments show good faith and reduce the arrearages piling up. Paying nothing when you had some ability to pay is the worst possible posture when you finally stand in front of the judge.
