Child support does not automatically stop when a child turns 18 in Florida — it stops when a specific legal condition is met, and that condition is often after the child's 18th birthday.
Florida law says child support continues until the child reaches 18 and graduates from high school, whichever happens later. If your child is still in high school after turning 18, the parent paying support must keep paying until graduation or age 19, whichever comes first. If your child has already graduated before turning 18, support stops at 18. The key is that both conditions must be satisfied — age alone is not enough.
The order does not stop on its own. The parent paying support does not receive a notice saying "you can stop now." Either parent can file a motion to terminate support once the conditions are met, but the safer move is to get a written court order confirming the end date. Without that order, the paying parent risks being held in contempt if the receiving parent claims support should continue.
Key Takeaways
- Child support in Florida continues until the child turns 18 and graduates from high school, whichever happens later — not at 18 alone.
- If a child is still enrolled in high school after their 18th birthday, support continues through graduation or age 19, whichever is earlier.
- The support order does not terminate automatically; one parent must file a motion to end it once the conditions are met.
- A written court order confirming the end date protects both parents and prevents disputes over when payments should stop.
- If a child is in college or trade school, support does not continue unless the original order specifically says it does.
The "18 and Graduated" Rule Explained
Florida Statute 61.13 sets the rule: support ends when the child reaches 18 years old and is no longer in high school. This is an "and" condition, not an "or" condition. A child who turns 18 in October but is still a senior in high school stays on the support order through graduation. A child who graduates in May at age 17 stays on the order until age 18.
The statute also caps support at age 19. Even if a child is still in high school at 19, support stops then. This is rare — most Florida high school students graduate by 18 — but it matters if a child has been held back or started school late.
The rule applies to biological children and adopted children. It does not explore to stepchildren unless the stepparent formally adopted them. If you are unsure whether adoption happened, check the original child support order or ask the court clerk.
What "Graduation" Means in the Order
Graduation means earning a standard high school diploma from a public or private high school. It does not include GED certificates, vocational certificates, or completion of alternative education programs, unless the original order specifically names those. If your child earned a GED instead of a diploma, support stops at 18 regardless of when the GED was earned.
If your child is homeschooled, the rule still applies — support continues until age 18 and the child has completed the homeschool curriculum. You may need to provide documentation of completion to the other parent or the court.
If your child drops out of high school, support stops at 18. The receiving parent cannot force the child to stay in school to extend support, and the paying parent is not required to pay beyond 18 if the child is no longer enrolled.
How to Stop Payments Once the Conditions Are Met
Once your child has turned 18 and graduated (or turned 19, or dropped out), the paying parent should file a Motion to Terminate Child Support with the court that issued the original order. This motion asks the judge to enter an order ending the support obligation. You can file this motion yourself or through an attorney.
Include in the motion the date the child turned 18, the date of high school graduation (or the date the child dropped out or turned 19), and a copy of the graduation certificate or transcript if you have it. The receiving parent has a chance to object — for example, if they claim the child is still in high school — so be ready to prove your facts.
Some counties allow you to file this motion online through the court's e-filing system. Others require a paper filing. Call the family law clerk's office in the county where the order was issued to learn the local process. Filing fees vary by county but typically range from $50 to $150.
What Happens If You Stop Paying Without a Court Order
Stopping payments without a written court order is risky, even if you believe the conditions have been met. If the receiving parent disagrees about the graduation date or claims the child is still in school, they can file a contempt motion against you. The judge may order you to pay back support plus attorney fees, even if you were technically correct about when support should have ended.
The receiving parent might also claim you owe support retroactively if they did not know you stopped paying. Getting a court order protects you by creating a clear, documented end date that both parents and the court recognize.
If you cannot afford the filing fee, ask the court clerk about fee waivers. If you and the other parent agree that support should end, you can file a joint motion, which is faster and cheaper than fighting it out.
College and Post-Secondary Education
Florida child support does not continue into college or trade school unless the original order explicitly says it does. Some parents negotiate orders that require support through age 21 or through college graduation, but this is a choice, not a legal requirement. If your order does not mention college, support ends at high school graduation or age 19.
If the original order does require college support, it typically specifies an age limit (often 21 or 23) and may require the child to maintain a certain grade point average or be enrolled full-time. Check your order carefully to see what it says.
If you want to modify an order to add or remove college support, either parent can file a motion to modify. The court will consider the parents' income, the child's needs, and the child's academic performance. This is a separate process from terminating support at 18.
Special Situations: Disability and Emancipation
If a child has a permanent disability that prevents them from becoming self-supporting, Florida law allows child support to continue past 18 and graduation. The parent receiving support must file a motion showing the disability and the child's need for ongoing support. The court may order support to continue indefinitely or until the child's circumstances change.
If a child is emancipated before age 18 — meaning they are legally declared independent — child support typically ends at emancipation, not at 18. Emancipation requires a court order and is not automatic. If you believe your child should be emancipated, consult an attorney about filing a petition.
If a child joins the military, gets married, or becomes pregnant, these events do not automatically end support in Florida. Support still ends at 18 and graduation unless the order says otherwise. If you believe one of these events should change the support obligation, you can file a motion to modify.
Frequently Asked Questions
What if my child turns 18 but is still in 12th grade?
Support continues through graduation or age 19, whichever comes first. You cannot stop paying just because the child turned 18. Once the child graduates, you can file a motion to terminate support, and it will end as of the graduation date.
Do I need to tell the other parent when my child graduates?
You should notify them in writing and keep a copy of the notification. Provide a copy of the graduation certificate or a transcript showing the graduation date. This creates a record if there is later a dispute about when support should have ended. It is not legally required, but it protects you.
What if the other parent refuses to stop collecting support after my child graduates?
File a motion to terminate support with the court. If the receiving parent continues to collect after the court order ends support, you can file a motion for contempt or seek reimbursement of overpaid support. Keep records of all payments made after the termination date.
Can I stop paying if my child drops out of high school at 17?
Yes. If your child is no longer enrolled in high school and is not pursuing a diploma, support ends at age 18. The receiving parent cannot require the child to stay in school to extend support. Document the date the child withdrew from school.
Does support continue if my child is in college?
Only if the original order specifically requires it. Standard Florida child support ends at high school graduation or age 19. If your order requires college support, it will name an age limit and may set conditions like full-time enrollment or grade requirements. Check your order to be sure.
