Some very excellent advice here. Definitely Stick to your guns on this one, that sounds like a terrible environment for anyone to live in. Until XP can make your son's safety and health #1 priority above the inconvenience of say having to pay rent for his own place, he is not mature enough to have visitation at his place. well that's my opinion anyway. Definitely get legal advice. Do everything you can to keep your son out of that house. Good luck with it all.
