FORMULA How Florida Calculates Child Support
Florida Statutes Section 61.30 governs child support. Florida’s guidelines include specific adjustments when the non-custodial parent has the children more than 20% of overnights (73+ nights). Florida applies 6% interest on arrears.
AGE When Does Child Support End in Florida?
Child support in Florida ends when the child turns 18 — or high school graduation, whichever is later. Support also ends upon the child’s death, marriage or emancipation. Important: In most cases support does not stop automatically — you need a court order. Stopping payments without a court order creates arrears even after the child reaches the cutoff age.
INTEREST Arrears Interest in Florida
Florida charges 6% annual interest on unpaid child support arrears. There is generally no statute of limitations on child support debt.
ENFORCEMENT Florida Child Support Enforcement
Florida has broad enforcement powers including wage garnishment, tax refund interception, driver’s license suspension, professional license suspension, passport denial, and credit bureau reporting. Criminal charges may apply for significant or long-term non-payment.
MODIFY Modifying Child Support in Florida
Child support can be modified in Florida when there is a material and substantial change in circumstances — typically a significant income change, job loss, new children from another relationship, or change in custody. Most states also allow a periodic review every 3 years. File a petition with the court — private agreements to change support are not legally enforceable.
