My grandmother passed away in 2009. She left her house to two of her children 50/50, her daughther who has lived in Arizona for the last twenty years and my granfmothers son who has lived with her at the house the last 17 or so years. Since my grandmother passed away, her son has continued to live in the house, paying all the bills including property taxes every 3 months of about 600$. Well for around two years now her daughter who legally owns 50% of the house has told ber brother (50% owner) to pay rent to make up for the revenue she would make if the house in question was vacant and rented out, although she hasn't paid any of the taxes on the property since she became 50% owner. My father has never asked for any money for taxes even though she owns 50% .
