My 87-year-old aunt suffering from moderate dementia fell and broke her hip resulting in a rehab care home. Her husband is deceased and she has no children. She lives alone. My mom (her sister) is detached so her business is left up to my brother, sister and I. She never gave anyone power of attorney or signed her home over to a family member. So now the arguments between us have begun. My brother and I want her to go back home if possible and my mom and sister want her to stay in the care home. What can/should we do?
