My dad remarried at age 80, and has dementia. My aunt is attorney-in-fact, and has medical power of attorney as well. She was also named as the only person other than Dad who could cash his CD. However, he is now in the hospital. His wife has gotten a lawyer to give her medical POA. The CD was changed, unbeknownst to my aunt to payable to the new wife on death. I am unable to get anything other than basic information from the hospital, such as 'he is stable'. My question is whether or not the power of attorney and the medical POA can be changed, or what to do about this situation. My dad was also convinced to buy his wife's daughter a car this year, and I believe his savings are gone, other than the CD. His wife is looking at putting him in a nursing home for the indigent, even though it is within the realm of possibility that he could go home with in-home nursing care. I want him to get the best care possible. What can I do? I appreciate any info. PLEASE help!
