I currently have medical POA on my mother who is late stages Alzheimer's. A situation has arised where I need a Durable POA. Mom can no longer feed herself or write anything down. I am my Mom's representative according to the federal government, as Mom receives SSDI. I also take care of the county for her medicaid/medicare. What can I do to get Durable POA, or will my Medical POA hold up in a court setting?
