My mom has lived with me for 5 years. My sister sold her home so she has money in the bank, but mom also has some land. Mom has left the land to me when she passes but if she "must" go into a nursing home my sister said she will "sell the land" to pay the nursing home. (She is moms POA). My question, is she "allowed" to do that before using moms "cash in the bank"? Thanks.
