Although child support enforcement is primarily left up to state enforcement, a non-payment of child support may also become a federal criminal offense under certain conditions. Using the commerce clause as its base of authority, Congress enacted the Child Support Recovery Act of 1992 (CSRA), Pub. L. No. 102-521, making a willful failure to pay a past due support obligation, with respect to a child residing inanother state, a federal offense. 18 U.S.C. § 228 The intent of the statute was to prevent non-custodial parents from fleeing across state lines to avoid paying their child support obligations and to facilitate recovery of unpaid child support.
