Child support generally continues until the minor child emancipates or until otherwise noted in the child support order. Under California law, a parent’s obligation to pay support continues until the child becomes 18 years old. However, the current support obligation may continue until the child is 19, if the child is unmarried and attending high school full-time. A court may order current child support to continue after the child emancipates because of special circumstances.
If there are arrears (past due support) owed on the child support case, the local child support agency may continue to enforce collection of the arrears until the case is paid in full, including any interest that may have built up.
