I have 3 siblings...My youngest sister is my mom's POA (but not her medical POA) and has been a total witch since my father passed!!! My mom was in assisted living and feel 2 days ago and is in the hospital with a fractured her hip. There are some medical issues that need to be decided, and I am not sure which one of us is Medical POA...Where/how do I find this out and get a copy?
