My 83 year old aunt's home is unfit to live in. My 63 year old male cousin lives with her. She has brain washed him that if it wasn't for her he would be dead. I have offered to help but my aunt is a controller and refuses the help and says they are getting along fine. She can't see to drive so my cousin goes with her everywhere to help her see. She has hit a motorcyclist who stopped to fast and side swipe a car, maybe more mishaps but this is all we know of. My male cousin has fallen and broken his knee cap, can't get around the house due to my aunts hoarding. what legal action can our family take to move him out and move her to a safe facility ?
