I live in another state than my court order , do I need a child support lawyer from that state or can I have one from my current residence?

Under the Uniform Reciprocal Support Act, the state where the child support order was issued generally has continued and exclusive jurisdiction over the modification or enforcement of a support order, if one of the parties or children reside in the state. The short answer to your question, is probably to first consult with a family lawyer in the state where the order was issued to confirm that is where you need to pursue your case.
