My husband and I co-own an old car that is on its last leg - or last wheel. My husband has Alz and can no longer give consent or sign anything anymore. I am his financial power of attorney. I am thinking of trading in the current car and getting another car. Do I need his consent to sell the current car? Does my role as his financial POA permit me to sell it without his signature/consent? Also, does he have to be on the title of the new car?
