My ex lied to get temporary custody
I have divorce decree that states I have custody in NV. My ex took my son to Massachusetts and got emergency custody order and was granted. I'm in NV with our other child, and can't appear in the scheduled hearing next week in MA for permanent custody.. I have emergency custody hearing in NV scheduled as well, but only after his hearing in Massachusetts. He lied to the judge to get this temp custody order, he's never paid child support, which I've also filed in NV. He violated the original order, and told the judge we were still married.. I now can't find my son! He has a disability and needs his care which he's not receiving in Massachusetts with his dad. I don't know what to do and I don't have a attorney. Do I just wait for my court date here in NV? What happens if he gets granted custody? Will courts here later overturn?
