The Uniform Interstate Family Support Act states that the first court to take jurisdiction has continuing and exclusive jurisdiction. While there are specified reasons that may move jurisdiction from one court to another, only one court has jurisdiction at a time. Inform the other courts which one was first. If you are talking about her filing with child support collection agencies in 5 counties, let them know that more than one agency is trying to collect on the same order. By the way, if you are talking about registering an order by a court in another court so collections can take place, the term is registering according to this act which all states are parties to.
