I am the current POA. It was decided in a family meeting with my mom that I was the best choice for financial and medical POA. My mom made this suggestion and all my siblings agreed. Now my mom is in the hospital after a bad fall. She is on pain medication. Two of my sisters have convinced her to change POA to them. I am most concerned with the financial aspect. The general feeling is that my sisters would take all the assets if there was an opportunity.
I only found out when I was doing a follow up with her primary physician.
Do you have any access to your mother's checking account? If so, you could check to determine if any payments have been made recently to attorneys.
How were the changes made? Did an attorney come to the hospital to have your mother execute new POAs?
