Long story short, if he knocks on your door and you open it, tell him you are going to get what he asks for, unless he is government, he is SOL. If he is government, he'll knock your door in and treat your place like a Axl Rose treats a hotel room. If he isn't government, he might try to sneak into your place and take stuff while you aren't looking and you can't even bring a case because everything is hearsay. However, they are like vampires in Buffy, if you invite them into your home, they can rip your shit up and if you try to force them to leave, they are within their rights to knife you in self-defence. Then again, that is just how stuff used to work in Texas where my brother was working, laws in massachusetts probably are more sympathetic to deadbeats who can't make their payments, so no worries greg.
