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.
