When Child Support Ends in Florida: Age, Graduation, and Other Stopping Points

Child support in Florida ends when your child turns 18, graduates high school, or becomes self-supporting — whichever happens last

Florida law sets a default end date: the month your child turns 18. But that is not always the final answer. If your child is still in high school when they turn 18, support continues through graduation or the end of that school year, whichever comes first. If your child has a disability, support may continue indefinitely. And if your child is 18 but not yet self-supporting, a judge can order support to continue longer. The paying parent does not automatically stop payments on the 18th birthday — the order must be modified or terminated in court, or both parents must agree in writing.

Understanding when support ends matters for both parents. The receiving parent needs to know how long they can count on that income. The paying parent needs to know when they can stop, and what steps they must take to avoid being held in contempt for stopping too early. The rules are clearer than many people think, but they do require action — not just the passage of time.

Key Takeaways

• Child support ends the month your child turns 18, unless they are still enrolled in high school, in which case it continues through graduation or the end of that school year.
• If your child has a mental or physical disability that prevents self-support, child support can continue past age 18 with a court order.
• A judge can extend support past high school graduation if the child is not yet self-supporting, though this is less common and requires a motion to modify.
• The paying parent must file a motion to terminate support or both parents must sign an agreement — support does not stop automatically on the end date.
• If your child moves out, joins the military, gets married, or becomes emancipated before age 18, support may end earlier.

The standard end date: age 18 or high school graduation

Florida Statute 61.13 sets the baseline: child support ends when the child turns 18. However, if the child is still enrolled in high school at that birthday, support continues through the end of that school year or graduation, whichever is earlier. This means a child who turns 18 in September but is a senior in high school will receive support through May or June, depending on when their school year ends.

This rule applies even if the child is not living with the receiving parent. The law looks at enrollment status, not living arrangement. Once the child graduates or the school year ends, support stops — no further court action is required at that point, though the paying parent should still file a motion to formally terminate the order to avoid confusion or future disputes about whether payments are still owed.

When support continues past age 18: disability and dependency

If your child has a mental or physical disability that prevents them from becoming self-supporting, Florida courts can order child support to continue indefinitely. The disability must exist before the child turns 18, and the receiving parent must file a motion before the child's 18th birthday or shortly after, asking the court to extend support. The court will examine medical evidence and the child's ability to work or live independently.

A child who is 18 but still dependent — meaning they cannot support themselves through work or other means — may also receive extended support if a judge finds it appropriate. This is less common than disability cases and typically requires the receiving parent to prove the child is making a genuine effort to become self-supporting (through school, job training, or employment) but has not yet reached that point. The court has discretion here, and outcomes vary by judge and circumstance. Extended support for dependency alone is not may provide and requires clear evidence that the child cannot yet live independently.

How to end child support: filing a motion or reaching an agreement

Child support does not stop automatically. The paying parent must file a Motion to Terminate Child Support with the court, or both parents must sign a written agreement to end support. If you wait until after the child turns 18 (or graduates), you are still responsible for payments until the court officially terminates the order. Filing the motion costs a court filing fee, which varies by county but is typically $200 to $400.

If both parents agree that support should end, you can submit a Stipulated Agreement — a document both of you sign — to the judge for approval. This is faster and cheaper than a contested motion. If the receiving parent objects to termination, the paying parent must attend a hearing and present evidence that the child no longer meets the legal definition of a dependent child. The judge will review the evidence and decide whether to grant the motion.

Events that end support before age 18

Child support can end before the child turns 18 if certain events occur. If your child gets married, joins the military, or moves out and becomes self-supporting, support may end early. If the child is emancipated — a legal process where a minor is declared independent by the court — support stops. Emancipation is rare and requires a formal petition, but it can happen if a teenager is living independently and working full-time.

If the receiving parent dies, support ends when ready. If the paying parent dies, the obligation typically ends as well, though the receiving parent may have a claim against the paying parent's estate depending on the circumstances. If custody changes and the child moves to live with the paying parent, support ends because the paying parent is now the custodian. Any of these changes should be documented with the court through a motion to terminate or modify, even if both parents agree the support should end.

What happens if the paying parent stops paying before the end date

If the paying parent stops making payments before the child turns 18 or graduates, they are in violation of the court order. The receiving parent can file a motion for contempt of court, and the judge can order the paying parent to pay all back support plus interest, attorney fees, and court costs. A pattern of non-payment can also result in wage garnishment, driver's license suspension, or other enforcement actions.

The correct way to stop paying is to file the motion to terminate or reach an agreement with the other parent. If you believe your circumstances have changed — you lost your job, your income dropped, or the child's needs have changed — you can file a Motion to Modify instead, asking the court to reduce or end support based on changed circumstances. This protects you from contempt charges while your case is pending and shows the court you are acting in good faith.

Frequently Asked Questions

Does child support end automatically when my child turns 18?

No. The court order remains in effect until it is formally terminated. You must file a motion to terminate or reach a written agreement with the other parent. If you stop paying without court approval, you can be held in contempt and ordered to pay back support plus fees.

My child is 18 but still in high school. Do I have to keep paying?

Yes, until the child graduates or the school year ends, whichever comes first. Once either event occurs, support ends unless the child has a disability or the court has ordered extended support for another reason.

What if my child drops out of high school at 18?

Support ends when the child turns 18, even if they drop out. The law says support continues through graduation or the end of the school year — but if the child is no longer enrolled, that condition is no longer met. The paying parent should file a motion to terminate to make this official.

Can child support continue past age 18 if my child goes to college?

Florida law does not require support to continue for college attendance alone. Support ends at 18 or high school graduation. However, if the child has a disability or the court has ordered extended support for dependency reasons, that support may continue regardless of college enrollment. A new agreement between parents could also provide for college support, but it would not be enforceable as child support under Florida law.

How much does it cost to file a motion to terminate child support?

Court filing fees vary by county but typically range from $200 to $400. If both parents agree, you can file a stipulated agreement, which costs the same but avoids the need for a hearing. If you cannot afford the filing fee, you may request a fee waiver from the court.
