Dad fell and fractured his hip. Was put into a Nursing Home on a short-term basis. Since his arrival he has been confused and delirious. We asked for an evaluation for dementia, and he was diagnosed with dementia. We believe this will turn into long term. I need to be the point person to assist in his care because my mother is elderly. She needs my help. The facility he is in now is an hour away. There are several facilities, with good reputations, closer to me.
Your father would at some point qualify for the help of Medicaid, then, while some of your mom's assets were preserved for her own care.
You will need to decide who is to serve as POA for your father if he is competent enough to appoint one. If there is already a will a Springing POA would likely be in it appointing your mother. She could serve with your helping her, but record keeping is needed.
I would advise you to start a diary now of everything to do with your Dad on a day to day basis.
I sure do wish you good luck and am glad your mom has your support here.
