This Act limits the modification of family support orders to a single state if one party to the dispute resides in that state, thereby eliminating interstate jurisdictional disputes. However, jurisdiction can be shifted to a different state if none of the parents or children continue to reside in the state, or if there is mutual agreement to move the case to another state. This Act has been adopted by every state.
The key results of this Act from a payroll perspective are that only one support order can be in effect at one time, and that an income withholding order can be sent to an employer directly from another state. When a withholding order arrives, an employer must follow the rules stated on the order, which will probably specify the address to which payments must be sent, the amount and duration of payments, and possibly the amount of administrative fees that may be withheld.
