My boyfriends ex girlfriend took off and moved out of state before their son was born. For the first year he was flying out to that state or flying them back here to see his son and then she flat out left him and shut him out. He hasn't seen his son in almost 2 years and she hasn't spoken to him either. He is wanting to take this to court but doesn't know where to file. Can he do it in the state he lives in or does it have to be the state the child was born in? We've heard both. Help!
