My son has three children 1 baby and one three year old girl and a 8year old boy who lives with me his grandmother and grandfather. His father wants him to live with him. the Question is can the boy share the room with the girl. And the other question is I have had temporary custody(given to me by the parents, I never asked for custody!!!) and have never been given a penny of child support. can i take him to court to pay child support. He promised he would help with support but never anything.
