In state of Virginia? This happened once to her and I found out afterwards. A family member knowing she was diagnosed with dementia took her to a dealership and she signed for a new car. She thought the family member was buying it and didn't know what she had done. Needless to say the dealership would not take the car back even after I explained and showed her medical condition. Because to them she seemed OK and their policy in Virginia was that the car could not be returned *24 hr window which we met but still she was stuck with paying the debt so I ended up taking the payments on the car to save her good line of credit. Is there anyway to alert companies that she has dementia to avoid such expensive transactions?
