I signed a lease June 1st, 2012 to live in a home. My landlord knew I would have a roommate. I pay the rent, my roommate handles the utilities and two of the utility bills are currently in his name and he receives mail at my address. I have given him sixty days verbal notice the leave the premise; he is not paying all of his bills as agreed upon, is inviting guests into the home far too often (25 days out of a 31 day month) , throwing parties with underage drinking. When asked to stop these behaviors, my roommate threatened me legally and sexually. He is refusing to leave unless I pay him $1,100 which he paid in portions in a security deposit upon entering the home. Is there any way I can remove him from the property or insure he will leave if I pay the deposit to him directly?
