He isn't on the lease, he never paid a deposit and he agreed to move out by Feb 1st, back in November. Now, he's threatening to sue, despite the fact that he's a drug addict and alcoholic who is relapsing again. I found him passed out in his car earlier this week, and I keep finding empty bottles in his room. We share a space that's broken into two rooms and both live and work there. What can I do to get rid of him?
