Joyce: If there is nothing in writing that states he has custody currently, then he probably doesn't. If he was paying child support, then he may be trying to keep the kids to avoid paying anymore. I would contact a Family Lawyer. They are the best when children are concerned. It sounds like parental alienation. My heart goes out to you. I have a grown daughter. My ex wanted custody of her, but she wanted to stay with me. She was an 18 year old full time college student at the time (his Lawyer told me because of her age she could live where she wanted, but since she was a full time student.......). Someday, the girls will see him for the type of man he is. I am sure they are missing their friends and life they had.
