Almost there, you are in the same boat I am (kinda...see the new thread I posted) however my son lives in Florida (actually he is in prison) but the child support order is out of NY. I did petition the NY court and I was told that since my son lives in Florida I can file a petition through the state of Florida. I does not make sence to me but that is what they said

My problem has been Florida is ignoring me...NY was quite prompt in getting back to me.

Hope this helps!
