Have you tried talking to your mom about how you don't wish to be kept from your father, and you certainly won't be used as a pawn in her feelings of upset about him? That you're old enough to determine for yourself how much or little you want him in your life?If that goes nowhere, then the fact is, the visitation plan was not made null.I do wish your father would apologize for being away and ask for his visitation back.You could write a letter to the court in your district. If you can find ANY papers relating to your parents' divorce or custody that has the court number on it, that would help. Just tell the judge what went on, say that it's not that you think either of them is in contempt, but that you need to get your visitation with your dad back on track http://www.nolegalaid.co.uk/
