My father in law came to visit a year and a half ago and hasn't left. He has an aide that comes in for a few hours a week. My children are not allowed to have friends over because he is staying with us. I live in the Northeast and he has my furnace at 71 in the winter and 68 in the summer. I have had to clean up bowel movements from my carpet, he stands in the entrance of our bathroom and just pees. I have a complete understanding and care for the man because of his age. Every few days my wife goes of the handle screaming and yelling at him. The kids and I walk on pins and needles just waiting for her to explode at us or him. I give up and want him out and a divorce. The man has been nothing but mean to me his whole life - he basically is a mean man and always has been. I am tired of the whole situation. I want my father in law out and then a divorce. The man has a sizable networth my wife will inherit and then divorce me anyways - I just want him out now. I have told him he needs to pay rent over and over and cover his cost to stay here which has been ignored. How can I kick him to the curb - he can easily pay the $5-8K a month to stay someplace nice, but my wife wants the money when he dies. Can I sue the estate for his back room and board and the damage to my home? Hardwood floors black, carpets and mattresses ruined?
