Have been caring for mom going on 5 years, and have POA, Executor, Proxy, etc. Youngest sibling stated two years ago "that she knows I'm living on mom's money" which is not the case. She pulled back stating it was just in saying, yet not apologizing. This past week on her annual visit she was telling her own son that mom pays me. When my dad passed in 2013, she helped herself to my mothers wallet and gained access to her accounts as a result of having her driver's license and social security card. It was then that she found out I was the POA, and at that time very anxiously inquired whether she could help. The question is, how could I verify with the bank (B of A) if she indeed has access and that all further access should be stopped? Is this something where an attorney should become involved? Does anyone know if there could be more than one username to each account and how would this be done? Appreciate all and any feedback.
