Blessing v. Freestone
520 U.S. 329 (1997)
United States Supreme Court
“not intended to benefit individual children and custodial parents”
The Supreme Court held that Title IV-D's “substantial compliance” requirement was not intended to benefit individual children and custodial parents, and did not itself create an individual entitlement to systemwide Title IV-D services.
Read carefully: this is narrower than saying “child support does not benefit children.” The decision did not abolish child support and does not say a parent owes nothing. It concerns whether individuals can sue to enforce systemwide compliance.
