Florida child support payments can be processed by the Florida Department of Revenue for $25. With this application the Florida child support authorities will establish paternity, order child support, serve as the intermediary for the collection of payments, review existing agreements and ensure the payments are keeping with guidelines set by the state. The custodial parent seeking support is obligated to keep all appointments with the child support services, maintain court appearances, and provide documentation that can help authorities locate noncustodial parents. Failure to meet these obligations will cause the state to close the child support case. Child support arrangements can be reviewed every three years or if there is a permanent and significant change to the income of the custodial parent or the needs of the children have increased substantially. Florida child support authorities can be contacted at 1-8000-622-KIDS.
