A relative contacted my mother and convinced her to sign a auto loan cosigner only. The relative will not disclose the contract she has it in her posession. Nor the details pertaining to the transaction. She the relative has posession of the car. But, it is in my mothers name only. I contacted the dealer and the owner and he called the relative. She has not responded to any communication. I have contacted Nissan Motor Corp. they have sent me fraud paperwork. My mother is responsible for this vehicle totally. Because she is blind. She is uninsurable on my fathers policy. My father did not give permission for the loan. But they are using his income without his signature. I've been in the car business since 1982. . please help.
