Child support enforcement in the United States at the Federal level is the responsibility of the Administration for Children and Families in the Department of Health and Human Services. There is an overarching framework of federal legislation (title IV-D of the Social Security Act) and regulation within which the states must operate if they wish to receive federal funding. States may also receive additional financial "incentive" payments for establishing paternity, or establishing or modifying child support orders. Although the federal child support program in the United States traces its origins to a congressional concern for recouping from absent parents some of the cash assistance paid to custodial parents, total U.S. child support collections in Federal fiscal year 2006 totaled $23.9 billion, $11 billion of which was paid to families who have never been recipients of public assistance.
