My father's been a permanent resident in a nursing home for 2.5 yrs, has mild dementia along with a number of other health issues and can no longer sign his name nor make competent decisions. He's been on Medicaid since admission into the nursing home however, my mother died recently and now his house has to be sold in order to pay for the reverse mortgage previously taken out as well as to retroactively pay Medicaid back for his care. I have a brother who I recently found out has been signing my father's name on his bank account checks for his own personal expenses and this needs to stop. I have primary medical POA for him, but don't know if that is enough. I would greatly appreciate any guidance as to what legally needs to be done in order to take care of my dad. Thank you in advance!
