My mom own a rental house and let a 53 year old man move in because he was homeless. He has paid no money for this sleeping and she would not let me do a lease for him. Now he is driving her car and my deceased step father's truck. He also spends the night with her??? She has given him money for mowing the yard and now is giving him the power to take care of and collect rent from this rental house. She told my brothers and I to stay out of her business. We can't let this man keep doing this. What do we do? I have been in charge of paying her bills for four years or longer now she wants me to turn all my information over to him. I believe she has dementia. This is the second time in a year she has done this with a younger man. The last one took her for about three thousands dollers. Help, I need answers.
