My mom and uncle have Poa over my grandmother who has alheizmer and is 95 years old. They are having the issues of one being more money hungry over the other. My grandmother left her home to my sister and I and my uncle is furious about my mother putting my sister name on house and thinks because we aren't her kids we shouldn't be left with anything. My mother stays and takes care of my grandmother in her home. He has called social services and made a complaint of neglect of her health and money to get her poa revoked. My mother doesn't know what to do and is also older and need to know procedures of what she should do. Please help!
