The Uniform Interstate Family Support Act {"UIFSA") is a Uniform Act that has been adopted by every U.S. State, in order to address the widespread problem of non-payment of child support obligations. The Act establishes rules requiring every state to defer to child support orders entered by the courts of the child's home state. The place where the order was originally entered holds exclusive jurisdiction, and only the law of that state can be applied to requests to modify the order of child support.
The Act also provides various direct interstate enforcement mechanisms. For example, it allows a caretaker parent to have an order mailed to the employer of the obligated parent, which will require that employer to withhold pay for the benefit of the child. Furthermore, it allows the caretaker parent to have an order mailed to an out-of-state court to get the other state to enforce the order.
