I have been caring for my grandparents for the past several years. They have 8 children. My mom and I live with them. My mom has health and financial POA. Grandpa has recently passed. 2 of my aunts and 2 uncles have become very controlling and just want grandma's money. They don’t care about anyone, not even their own mother. Grandma gets very agitated after they visit. They know nothing about her, not even her age or what year she was born in. They recently had petitioned for guardianship. What would it be like to fight it, with my mom and aunt who have POA and secondary POA? The siblings that have filed have not been involved.
