My brother, who was never in my parents or my life until 2 days before my father died. After my father died, he took advantage of my mothers grief and failing mental capacity and had her sign over POA to him. He has been divorced 3 times, alcoholic and is dependent on pain medication. Unfortunately my mother has a major stroke under his "care" and is in a nursing home. He is spending my fathers estate money on himself. I can not do anything about this because I can not afford attorney. He has now been arrested for selling drugs. Can he lose his POA if he is convicted?
