Child Support Services — How They Work in 2026
State child support agencies (IV-D agencies) provide free services to establish, collect, and enforce child support orders. Services include locating the other parent, establishing paternity, setting up support orders, and collecting and distributing payments.
Child support amounts are determined by state guidelines based on both parents' incomes, number of children, and custody arrangements. Courts can modify orders when circumstances change significantly.
