Child support in Texas does not automatically stop at 18. Under Texas Family Code Section 154.001, your obligation runs until the child turns 18 or graduates from high school, whichever happens later, and even once that date arrives, wage withholding will keep coming out of your paycheck until a judge signs an order telling your employer to stop.1State of Texas. Texas Family Code FAM 154.001
When the Obligation Actually Ends
The ordinary end date is 18 or high school graduation, whichever comes later.2Justia. Texas Family Code Chapter 154 – Child Support If your child turns 18 in January but doesn’t graduate until May, you owe support through May. If your child graduates at 17, you still owe through the 18th birthday.
Four other events end the obligation before adulthood:1State of Texas. Texas Family Code FAM 154.001
- The child marries.
- A court removes the disabilities of minority (emancipation).
- The child dies.
- The child enlists in the military. The Texas Attorney General’s office treats enlistment as ending the obligation because it removes the child from parental dependence.3Office of the Attorney General. Military Parents and Child Support
Why Wage Withholding Keeps Coming Out
This is where most paying parents get caught. The child graduates, you assume everything stops, and the deductions keep appearing on your pay stub. That isn’t a payroll mistake. Withholding is driven by a court order, so neither you nor your employer has the authority to end it without a new court order.
To shut it off, you go back to the court that issued your child support order and file a petition to terminate the income withholding. The other parent gets a chance to respond. If everyone agrees the obligation has ended, the hearing is usually short. If the other parent disputes it — because arrears remain, or because they believe support should continue — the court sets a contested hearing. Once a judge signs the termination order, it has to reach your employer’s payroll department before the deductions actually stop.
Waiting it out is not a plan. Every dollar withheld after the obligation ends is still being processed through the state disbursement system, and recovering overpayments is far harder than preventing them. File the petition as the end date approaches rather than after.
When Support Can Run Past 18
A Child Still in High School
If your child is enrolled in an accredited secondary school on their 18th birthday, support can continue. Under Section 154.002, the child must be working toward a high school diploma and meeting minimum attendance requirements, which for private schools means the attendance standard that school sets.4Justia. Texas Family Code Chapter 154 – Child Support – Section 154.002 A parent can petition for this before or after the child turns 18. If the child drops out or stops attending, the basis for continuing support disappears.
A Child With a Disability
Texas courts can order support indefinitely for a child with a mental or physical disability that prevents self-support. Under Section 154.302, two things must be true: the child requires substantial care and personal supervision because of the disability, and the disability existed, or its cause was known, before the child’s 18th birthday. Payments can go to the custodial parent, a guardian, directly to the adult child if they can manage their own finances, or into a special needs trust.5State of Texas. Texas Family Code 154.302 – Court-Ordered Support for Disabled Child
One warning if your adult child receives Supplemental Security Income: the Social Security Administration counts the full child support payment as unearned income, with no partial exclusion for adults.6Social Security Administration. Child Support Payments Ongoing support can reduce an SSI check dollar for dollar, which is a reason many families route payments through a special needs trust instead.
Unpaid Support Doesn’t End With Childhood
If you owe back support when your child turns 18, the debt stays. The income withholding order remains in effect until the arrearages are paid off in full, and the other parent can keep pursuing enforcement through the courts. Reaching adulthood changes nothing about what you already owe.
Unpaid child support also accrues 6% simple interest per year from the date each payment became delinquent until it’s paid.7Texas Public Law. Texas Family Code 157.265 – Accrual of Interest on Child Support A $20,000 arrearage adds about $1,200 a year in interest alone. The Attorney General’s enforcement tools — license suspensions, passport denial, liens, bank levies, and tax refund interception — remain available after the child turns 18 as long as arrears exist.8Office of the Attorney General. How We Enforce A court can also hold a delinquent parent in contempt, and intentional nonsupport of a child under 18 is a state jail felony under Texas Penal Code Section 25.05.
Does Child Support Cover College in Texas?
No. Texas does not require parents to pay for college as part of a child support order, and no statute extends the obligation through a degree. Parents can voluntarily agree to share college costs in a divorce settlement, and when those terms are written into the decree they become enforceable as a contract. If you want the other parent to contribute to tuition, it has to be in the final order; a court will not add it on its own after the fact.
