 Okay, so here's what I would think, and I'm very sorry to hear about this situation, and it must be really painful. My first thought would be to find out whether or not they can evict your brothers. I know it sounds terrible, but if they're causing such mayhem, that seems to me the first step to consider. Now, in some states, and I'm not a lawyer, obviously I can't give legal advice, so go consult a lawyer.
