My sister who was my mom's (89) caregiver passed away suddenly last week. She lived with my mom. My mom can hardly see, hear or walk, her memory is also failing. She depends on someone to take her anywhere. She can't live with us because she cannot go up and down stairs. I live an hour away. My (44) year old Nephew who has been living there and would have been kicked out many years ago if not for my sister (his mother) was taking advantage of his mom. Stole money from her, she was his enabler. He doesn't work depends on SS disability because of a foot injury, doesn't have a valid driver's license, former drug addict although I suspect he still does drugs. In my mom's "eyes" he is a saint and does anything she asks. Him and I have had some blowup arguments because he feels he is entitled and refers to my mom's house and property as his. I am legally my mom's POA. His sisters have disowned him. I need to get my mom away from there and sell her home and property before he tries something. Can I get her Primary Care doctor to sign something that says she is not capable of making rational decisions?
