I was asked to become my mother's 86 yr. olds best friend POA after my mom was told she had cancer (mom passed away). We went to her attorney & got the papers. A year later Loretta had brain surgery. I was taking care of her for months and had her in rehab/nursing facility. She was on the long road to recovery. While there, someone else came by with a notary and told her to agree to have her POA (she wasn't in her right state of mind) would that even be legal?
