If she doesn't, she will co own with whoever inherited his share. She could buy them out, they could buy her out, or they can sell it and split the proceeds. If the person inheriting is family, they may agree to let her live there if she covers maintenance, or credit her with what she spent on the house if they buy her out or sell. Otherwise, I doubt her paying for costs on a house she owns will be legally enforceable as an agreement for her to own his share as real estate agreements generally need to be in writing.
Yes that 50/50 purchase way back when may have had a right of survivorship, which sundown grandpa may have forgotten about in his disinheriting rants.
