I have the DPOA for my mom's business affairs as well as healthcare. Her cognition is markedly changed. Our current documents were prepared 10 years ago, when my father passed. My mom's cognition is clearly altered now. The documents state that I am to carry out the responsibilities as POA, but that she may revoke them at any time. How do I go about having her evaluated and if the evaluation shows dementia who needs to see that form in order to bring the POA into irrevocable status?
