Child support does not automatically stop when your child turns 18 in Texas
Texas law requires child support to continue past age 18 if certain conditions are met. The order does not end on the child's birthday — a parent or the court must take action to stop it. The most common reason support continues is if the child is still in high school. Even if the child has graduated or left school, support can extend to age 19 or 20 depending on when they finish their senior year.
If your child turns 18 while still enrolled in high school, the obligor (the parent paying support) must keep paying until one of three things happens: the child graduates, the child turns 19, or the child drops out. If the child is no longer in high school and has not graduated, support ends automatically on the child's 18th birthday. The paying parent does not need to file anything — the obligation simply stops.
Key Takeaways
- Child support continues past 18 only if the child is still enrolled in high school at the time of their 18th birthday.
- If the child is in high school, the paying parent must continue support until the child graduates, turns 19, or drops out — whichever comes first.
- If the child is not in high school when they turn 18, support stops automatically with no court action needed.
- The receiving parent should notify the paying parent and the court if the child drops out of school or if circumstances change.
- Support never continues past age 19 in Texas, even if the child is still in high school.
What "still in high school" means under Texas law
Texas defines a child as still in high school if they are enrolled in a secondary school and attending classes. The child does not have to be passing their classes or making progress toward graduation — enrollment and attendance are what matter. A child who is 18, enrolled, and attending is considered a dependent child for support purposes.
If your child turns 18 in September and is a senior, support continues through graduation. If your child turns 18 in June after graduating, support stops that day. If your child turns 18, is enrolled as a senior, but then drops out in October, support stops when the school reports the dropout — not when the child physically leaves.
How the paying parent finds out support should stop
The court does not send a notice on the child's 18th birthday telling the obligor that support has ended or will end. The paying parent is responsible for knowing the child's enrollment status. If the child is no longer in high school, the obligor should stop paying and notify the receiving parent in writing that the obligation has ended.
If the receiving parent continues to demand payment after the child is no longer in high school, the obligor can file a motion to enforce the termination. The obligor will need to show proof that the child was not enrolled — a letter from the school, a withdrawal form, or a transcript showing the child is no longer a student. Without this proof, a court may order the obligor to pay arrears (back payments) plus interest.
What happens if the child is in college or vocational school
Enrollment in college or a vocational program does not extend child support past 18 or 19. Texas law specifically limits the extension to high school enrollment. A child who graduates high school and then attends community college, a four-year university, or a trade school is no longer a dependent child for support purposes, and the obligation ends.
Some child support orders include language requiring the obligor to pay for college or vocational training, but this is a separate agreement — not automatic under state law. If the original order says the obligor must pay for higher education, that language remains in effect until the court modifies it. If there is no such language, the obligor has no legal duty to pay for college.
Modifying or enforcing the order when the child turns 18
Either parent can file a motion to modify the child support order if circumstances change before or after the child turns 18. If the child drops out of school, the obligor can file to terminate support immediately. If the obligor stops paying when the child is still in high school, the receiving parent can file an enforcement action to collect arrears.
The parent filing must submit proof of the child's status — school records, enrollment verification, or a transcript. The court will review the evidence and issue an order. If the obligor owes back payments, the court can add interest and court costs. If the receiving parent was wrong about the child's status, the court can order a refund of overpaid amounts.
What to do if you disagree about the child's enrollment status
If the obligor believes the child is no longer in high school but the receiving parent disagrees, do not simply stop paying. Contact the school directly and request an enrollment verification letter. This letter shows whether the child is currently enrolled and attending. Provide a copy to the receiving parent and keep a copy for your records.
If the receiving parent still demands payment, send a written notice stating that you have verified the child is not enrolled and that support has ended under Texas law. Keep a copy of this letter. If the receiving parent files an enforcement action, you can present the enrollment verification to the court. If you stop paying without proof and the child was actually still in school, you could owe arrears plus penalties.
Frequently Asked Questions
Does child support stop automatically on the child's 18th birthday?
Only if the child is not in high school. If the child is enrolled in high school, support continues. The obligor must keep paying until the child graduates, turns 19, or drops out. There is no automatic notice from the court — the obligor must verify the child's enrollment status.
What if my child is 18 and still in high school but refuses to go to class?
Attendance and enrollment are both required. If the child is enrolled but not attending, the school may report a dropout or truancy. Once the school formally withdraws the child, support ends. If the child is simply skipping class but remains enrolled, support continues. The obligor should request written confirmation from the school of the child's status.
Can I stop paying child support if my child turns 18 and gets a job?
Not based on the child's employment alone. Support continues if the child is in high school, regardless of whether they work. If the child is not in high school, support stops at 18 regardless of employment. The child's income does not affect when the obligation ends.
What if my child is 18, in high school, but living with the obligor?
The child's residence does not change the support obligation. If the child is enrolled in high school, the obligor must continue paying support even if the child lives with them. The obligation is based on enrollment status, not custody or living arrangements. The obligor can file a motion to modify support based on changed circumstances, but support does not stop automatically.
Can the court extend child support past 19 if the child is still in high school?
No. Texas law sets 19 as the absolute maximum age for child support, even if the child is still enrolled in high school. If the child has not graduated by age 19, support ends. The court cannot extend the obligation beyond 19 under any circumstances.
