The amendments involved two important changes to URESA. The amendments sought to correct a problem created by URESA. In some cases, the responding court only had evidence from the obligor and not have any evidence from the initiating state or the obligee. The responding court, with only one side represented tended to benefit the obligor. The Commission's solution was to amend URESA so the initiating state and the obligee would provide evidence to the responding court along with the original case file, so the responding court would have positions from both parties. The Commission also provided a second method to obtain redress via civil enforcement. The new method permitted the obligee to register the foreign support order in a court of the obligor's state, and present that case directly to the foreign court. RURESA provided new protection for mothers against noncompliant fathers; however, RURESA created a new problem—multiple support orders. Since every state could both enforce and modify a support order, a new support order could be entered in each state. Thus, if the father moved from State A to State B to State C to State D, and if the mother continually registered and had the order modified, then there would be four separate and independent support orders. RURESA allowed state courts to modify the original order so long as the court applied its own procedural law and the law of the original state, unless that contravened its own public policy. The Commission intended to correct the problem of inconsistent multiple orders by only allowing the support orders to be modified based upon a single state's law. In theory, states A, B and C could only modify a support order based upon the original state's substantive law; thus, all the support orders should be identical. In practice, however, this rule created ambiguities concerning whether child support guidelines are procedural or substantive, and if substantive, whether application of that substantive law contravened some public policy. The multiple order issue remained a problem. In 1992, NCCUSL completely revised and replaced URESA and RURESA with the Uniform Interstate Family Support Act (UIFSA) to correct the problem of multiple orders. UIFSA corrected this problem by providing that only one state would possess the power to make or modify child support at any one time ("continuing exclusive jurisdiction"). The state with continuous exclusive jurisdiction would use its own child support guidelines. Thus, if the child or either one of the parents remained in the original state, then that state retained jurisdiction and only that state could modify the support order.
