But like everything else you best cover your bases. I would have your roommate use your address to receieve mail. I would also get him to change the address on his Dirvers Licence to yours. Or register to vote in your district. You know, some paper trail that shows he lives there.

Lastly I would go over your state laws. Just because I can get away with it doesn't mean you can. It should be under co-habitating patients.
