A friend wrote a check for $30K against their AMEX account. They deposited it into my personal bank account. I then withdrew funds in the form of a cashier's check to purchase a vehicle. All records for this vehicle are in my name only. Four months after purchasing the vehicle, my friend wrote up a simple contract for repayment. I was to pay $400/month at 2% interest until/if they sold their home (which would then cancel the loan per their words) or until she cancelled it voluntarily. We both signed this agreement; however, it was not notarized. Three weeks after this signing, she notified me in writing that she is cancelling the repayment agreement and considered the loan resolved. She indicated, also in writing, that she would not be changing her mind. She stated that I can, or not, pay her back if I wanted to. Our relationship is now over. I had been paying her $300/month, not because the agreement was still being adhered to, but because I thought it was the right thing to do. She is now wanting to revert back to the original agreement we signed and I refused. She claims to be consulting an attorney. Would anybody know how to interpret the legalities of the agreement to repay? What actions can/should I take? I am even thinking of transferring ownership of the vehicle just so she cannot try to take it back.
