I have been the live in primary caregiver for my father, (and mother before she passed last year), for almost 4 years. My sister who lives in another state is POA. I transport my father to appointments and take him places in my own personal car. Now my sister is trying to tell me I can't loan my car to MY son, because, "what if something happens and you don't have your car?". The family trust pays for the gas in my car and the insurance, however, if I let my son drive it, he puts gas in it, with his own funds.
