On my moms General Durable POA and Medical POA my sister is agent, then I am the successor agent then my brother. Can my sister tell a medical practice not to give me medical records or talk to me if I am on the POAs? This happened when I attempted to get medical records which my sister knew I was getting. After leaving several messages with no return calls I finally just said I was the daughter and they put me through to the person that I left messages with. She stated that she could not talk to me and that I was not to get moms medical records. According to this person my sister had me blocked. I am discussing what happened and why this happened with my sister tomorrow but for legal reasons I need clarification on the POAs. If my sister is out of town and I am next on the POAs how can I communicate with the medical office if I need to. Any thoughts. Thank you.
