My mother has been living with Alzheimer’s for a number of years. She has always been very independent and insisted on managing her own affairs even after my father passed away. Unfortunately of late, she has deteriorated very badly, to the point where I am very concerned about her financial situation and her care. I know my father left her some money, and I want to make sure that this money is correctly used for her care. But am I allowed to take over control of her affairs?
