National Child Support Enforcement Act

National Child Support Enforcement Act - Amends part D (Child Support and Establishment of Paternity) of title IV of the Social Security Act to require that in order for any State to be eligible for payments pursuant to title IV or title XIX (Medicaid) of the Act, to have enacted and implemented a State law providing for the collection of child support through a mandatory wage withholding system satisfying the requirements of this Act.

Requires a State system to: (1) apply in every case where child support has been ordered by a court or administrative process of the State; (2) provide for withholding from wages per pay period of child support payments due, plus any past-due support (to a maximum of 25 percent of gross pay); (3) require that any charges or fees imposed covering the costs of collection be paid by the individual from whom the amounts were collected; (4) utilize the services and facilities available under part D to locate individuals owing support, administer the withholding process, and distribute amounts withheld; and (5) include such other provisions as the Secretary of Health and Human Services determines necessary and appropriate.
