My sister had a stoke and signed forms for me, her brother, to be POA. Upon verifying that my sister wanted to me to be POA, the Hospital Social Worker prepared the documents, phoned a notary that the hospital uses and gathered witness from patients rooms. We got the documents signed. Three banks have accepted my original copy as authentic to access my sister's accounts and made their own copies! However the Benefits and Retirement Department of my sister's employer is requesting a certified copy of the power of attorney! I know for a fact I need to keep the original. So how do I go about satisfying their request for this so called: "Certified Copy of POA" to access my sister's 401K?
Is there another way to get them to accept differently? Where can I get a Certified COPY of POA?
