My mother recently signed over POA to both me and my brother. My brother and his wife have taken charge without asking me if this was ok. They've removed her from her home and have taken her to live with them in a cramped home. Whereas I have space and are being told you can't take her. She is due for surgery and would like to use her old doctor yet my brother and his wife have taken it upon themselves to find her a new doctor. She's in the beginning stages of Alzheimers, she has clear moments in between. When I talk to her it's all fine she tells me her wishes and when I say I will help, suddenly I get pushed away and they take over. What are my rights and is a POA valid in every state? They are not abusing her but persuading her to think like them. We are not children we are in our 50's and I am the oldest. I want to know legally can I do something against my brothers actions? or do I have to sit back in another state and wait till it all falls apart. I am very torn right now.
