My mother and her brother own the home their mom left them. My uncle has gotten verbally abusive to her, to me, and threatened to kill my brother and my cat. He owns guns, and is very unpredictable. My mother wants to buy him out of his half of the house and is now getting the information from the bank about appraisal of the house and then a loan for half of that amount. I am concerned for her needing some sort of mediating party that can document properly the things he says and agrees to because up until this point every agreement they ever have is verbal and he is drunk a lot of the time and doesn't remember what he agrees to and goes back on his word often. We don't have a lot of money and this is going to be a strain financially already so we need a lawyer just when?
