Although there is a full faith and credit clause in the United States Constitution, 28 U.S.C. 1738, it was not clear that one state’s child support order is enforceable by another state. And even after UIFSA was enacted, parties continued to jump from state to state to try to pay less child support or avoid paying child support.
So Congress enacted the Full Faith and Credit for Child Support Orders Act (“FFCCSOA), 28 U.S.C. 1738B. The law requires that all states territories give full faith and credit to child support orders of sister states as long as the sister state properly exercised jurisdiction over the parties and the subject matter.
