| Under the one-order system established by UIFSA, it is | 
| necessary to provide a new procedure to eliminate the multiple | 
| orders so common under RURESA and URESA. This requires | 
| cooperation between, and deference by, sister-state tribunals | 
| in order to avoid issuance of competing support orders. To | 
| this end, tribunals are expected to take an active role in | 
| seeking out information about support proceedings in other | 
| States concerning the same child. Depending on the | 
| circumstances, one or the other of two tribunals considering | 
| the same support obligation should decide to defer to the | 
| other. In 1992 UIFSA took a significant departure from the | 
| approach adopted by the UCCJA ("first filing"), by choosing | 
| the "home State of the child" as the primary method for | 
| resolving competing jurisdictional disputes, thereby adopting | 
| the choice of the federal PARENTAL KIDNAPPING PREVENTION ACT, | 
| 28 U.S.C. 1238A Section (C). Given the pre-emptive nature of | 
| the PKPA, and the possibility that custody and support will | 
| both be involved in some cases, the PKPA/UIFSA choice for | 
| resolving disputes between competing jurisdictional assertions | 
| was followed in 1997 by the decision of the Conference to | 
| replace the UCCJA with the UCCJEA. If the child has no home | 
| State, however, "first filing" will continue to control. |
