Have them sign a contract guaranteeing they won't sue you
Congratulations! You've just subjected your loved ones and family friends to what is more than likely the worst night of their lives, but unfortunately you've left your self open to some potentially costly lawsuits that could drain you of your life savings. Well, make sure they've signed a contract ensuring they won't sue you first. This is potentially another service that the mentally disturbed ex-convicts you've invited can handle. No one is going to refuse to sign a contract when seven foot tall Leon "Stabby" McGee asks nicely.
