Unmarried Couple Splitting up with Joint Ownership of Home
Because you're not married, its a partnership agreement, and unless there's a written contract, either the two of you agree on how to handle the home, or it's off to court you go. If you were both supposed to pay for the home, and he failed to for a a while, that would put him in breach of contract which I would think gives you a good position in court. On the other hand, if you are at all concerned about your safety from this louse, remember, he knows exactly where the house is.
