I need to explain to my Sis that while Mother gave her rights to sign for medical treatments this is not the same as having the POA. Sis stated to a AL employee that she had POA but she doesn't. Mother has never signed and notarized any form for POA only the Medical directives and assignment which only requires a simple witness signature. I think because Mother has Sis' name on her financial accounts that is enough. Help me explain the difference better!
