What is IV-D?
The child support service called the IV-D (4-D) Program is a federal, state, and local effort to collect child support from parents who are legally obligated to pay.
Established in 1975 as Title IV-D (4-D) of the Social Security Act, the child support enforcement program functions in all 50 states and some foreign countries as well.
Through the IV-D Program absent parents can be located, parentage can be established, and support orders can be enforced to ensure child support payments.
