I am the mother of a 12 year old boy whom I share joint custody of with his father, but I am the primary custodial parent. My question is why can't the police retrive my son from his fathers possession when the father failed to return the child home after visitation? They say I have to go back to court and file a motion to hold him in contempt. Do I not have more "rights" than his father, or do we share them equally?
