My sister who has medical power of attorney has decided to take our mother out of a nursing home. Take her home. My 20 yr old niece is going to sleep there at night, and my sister is going to stay there during the day. She admitted to paying her daughter to care for our mother. And thinks nothing is wrong with it and claims her daughter is responsible. I think it is stealing our mother's money to pay her daughter. My sister says she is "saving mom money" by doing this. I really need advice.
