How Do I Stop Child Support When My Child Turns 18 in Florida?

To stop child support in Florida when your child turns 18, start by reading your existing order. If it was entered on or after October 1, 2010, it must state the exact date support ends, and the obligation terminates on that date without a new court filing. If your order is older or lumps multiple children into a single payment with no end date, you have to file a petition and get a judge to sign an order terminating support. Either way, the income withholding coming out of your paycheck will not stop on its own — you have to send paperwork to your employer and the state disbursement unit.

Check Your Order for a Termination Date

The single most important question is what your order says. Every Florida child support order entered on or after October 1, 2010 is required to include the specific month, day, and year support ends, along with a schedule showing what happens as each child ages out.1Florida Legislature. Florida Statutes 61.13 – Support of Children; Parenting and Time-Sharing; Powers of Court If yours has that language, the obligation ends on the date printed in the order. No new filing is needed to terminate it. Your only remaining task is turning off the paycheck deduction.

Older orders often lack a specific end date. A common problem is the lump-sum order: one figure covering multiple children with no per-child breakdown, something like “$1,200 per month for the parties’ three minor children.” Orders written this way stay fully enforceable at the full amount until you go back to court and ask for a reduction or termination. Silence is not a defense. Until a judge signs a new order, you owe what the old one says you owe.

Florida sets 18 as the age of majority by removing the “disability of nonage” at that age, which is why 18 is the baseline end point.2Florida Legislature. Florida Statutes 743.07 – Rights, Privileges, and Obligations of Persons 18 Years of Age or Older

When Support Continues Past 18

Two situations extend the obligation beyond the 18th birthday, and both are worth knowing before you assume you’re done.

If your child is still enrolled full-time in high school at 18, support continues so long as the child is performing in good faith with a reasonable expectation of graduating. It ends at graduation or the 19th birthday, whichever comes first.1Florida Legislature. Florida Statutes 61.13 – Support of Children; Parenting and Time-Sharing; Powers of Court This trips up parents of seniors with fall birthdays.

If your child has a mental or physical disability that began before age 18, a court can order support to continue indefinitely. Orders for a dependent adult child have no automatic end date and stop only when a court signs a new order terminating them.2Florida Legislature. Florida Statutes 743.07 – Rights, Privileges, and Obligations of Persons 18 Years of Age or Older

Filing a Petition to Terminate an Older Order

If your order has no built-in termination date, you need a signed court order to end it. Here’s what that process looks like.

File a supplemental petition to terminate child support with the clerk of the circuit court in the county that issued the original order. Florida’s court system provides Form 12.951(a) for this purpose. You’ll need the original case number, both parents’ full legal names, and your child’s name and date of birth. Attach a certified copy of the child’s birth certificate. If your child turned 18 while still in high school and has since graduated, attach proof of graduation. The filing fee runs around $50.3Florida Courts. Petition to Disestablish Paternity and/or Terminate Child Support Obligation

Serve the other parent through formal service of process. That means a sheriff’s deputy or a certified private process server. File the proof of service with the court once it’s done.4Florida Legislature. Florida Statutes 48 – Process and Service of Process

Once a judge reviews and signs the order, keep certified copies. That signed order is what legally ends your obligation and sets the effective termination date. Courts can make termination retroactive to the 18th birthday even if you file later, but delay makes the accounting messier, so filing promptly is worth it.

Stopping the Paycheck Deduction

This is the step most parents miss. The income withholding order sitting with your employer does not expire when the child ages out. It stays in force until legal action ends it.5Florida Legislature. Florida Statutes 61.1301 – Income Deduction Orders Do nothing and your employer will keep sending money to the Florida State Disbursement Unit month after month.

Once you have a signed termination order, or once your post-2010 order’s built-in termination date has passed, send two documents to your employer’s payroll department: a copy of the court order and a completed Income Withholding Order form marked for “Termination.” Send the same package to the Florida State Disbursement Unit at P.O. Box 8500, Tallahassee, FL 32314-8500.6Circuit 19. Income Withholding Order Form Deductions continue until payroll processes that paperwork.

One important catch. If you owe any arrears, the income deduction does not stop when current support ends. It continues at the same rate and gets applied to your back balance until either the balance is paid in full or a court modifies the amount.5Florida Legislature. Florida Statutes 61.1301 – Income Deduction Orders

If the Department of Revenue Manages Your Case

Many Florida child support cases run through the Florida Department of Revenue under the Title IV-D program, especially where a parent applied for state assistance or asked the state for enforcement help. In those cases the DOR has its own procedures.

The DOR states that orders will generally stop when a child turns 18, with the same exceptions for high school students, disabled children, orders from other states, or orders that specifically extend support.7Florida Department of Revenue. Case Closure But closing your DOR case is not the same as terminating your court order. The DOR stops working the case; the underlying order remains enforceable until a court or the DOR formally terminates it.8Florida Department of Revenue. Income Withholding Call the DOR directly to confirm whether your order qualifies for administrative termination or whether you still need to file in court.

Arrears Continue After Support Ends

Terminating current support has no effect on past-due amounts. Florida statute is explicit: ending the current obligation does not terminate arrears, retroactive support, delinquencies, or costs.9Florida Senate. Florida Statutes 61.14 – Enforcement and Modification of Support, Maintenance, or Alimony Agreements or Orders The balance is owed regardless of how old the child is now.

Interest accrues on arrears at the statutory rate established under Section 55.03. Payments get applied first to any current support due, then to delinquent principal, and finally to accrued interest.9Florida Senate. Florida Statutes 61.14 – Enforcement and Modification of Support, Maintenance, or Alimony Agreements or Orders The longer the balance sits, the more interest stacks on it.

Enforcement If You Owe Back Support

State and federal collection tools do not switch off when a child turns 18. If you have unpaid arrears, expect any of the following to continue or start:

If you can’t cover the full amount, you can petition the court to modify the repayment schedule. The debt itself stays. Ignoring it is not a workable plan.
