My nephew is 16, and lives with my brother, who has full custody. He gained custody when my nephew was 2, due to his mother being unfit. The problem is that now my brother is going through a very bad depression, and has basically given up on life (quit paying bills, doesn't leave the house, about to lose good job). His new wife is getting ready to leave him, and based on his current mental state, we want my nephew to come live with us. We are scared what he will do once his wife leaves. Does my nephew have the right to choose where he wants to live, even if his father doesn't agree? Does he have to be emancipated in order to do this? He doesn't want to go live with his mother, and has stated he wants to live with us. What steps can we take?
