Legal Question in Family Law in Maryland

First of all, if there is a written agreement or court order setting forth the schedule and child support you described, your wife should enforce that by letting the father know that if he doesn't adhere to it he will not get visitation. If this is all informal, she should go to court for a court order. As for the move to FL, she will have to come to some agreement or failing that file a court petition proposing a visitation schedule that gives him reasonable access to the children. This may involve her covering the transportation cost of sending the children back here unless he is willing to come there for visits. The children's ages are important here.
