Mom can't live on her own and we checked assisted living facilities near her old home town where some of her brothers and sisters live. Mom did not like any of the facilities and wanted to move in with her much younger sister. I had POA and Health care responsibility, plus oversight of all financials. The sister was to provide a family living situation (she has lots of adult children and grandkids) also provide company for mom along with a more consistent diet on a daily basis. Now the sister has convinced Mom that I live too far away and has had everything switched to her name. The whole family (me -my brother and the grandkids) know that the sister is using mom's money like her own piggy bank. Mom won't talk to anyone about this because she has blind faith in her sister. However when I and the family try to talk to mom about this she hands the conversation to her sister. And the sister's response is your mother wants me to do this for her. What do we (the immediate family) do in this situation?
