my mother in law willfully gave me a truck she owned after my vehicle broke down. she did not want money but I insisted. we went to the DMV together and she signed everything pertaining to ownership over to me instantly. we later came to an agreement of 600, 100 per month. there is no written agreement of any kind, no bill of sale. I paid cash for two monthly payments and then the truck broke dwon from a busted timing chain, as the truck was already used. It was verbally communicated that my mother in law did not feel right asking for money for a truck that no longer worked, and she suggested to sell it. I did sell the truck and got 500. Me and my wife moved in next door to the mother in law and arguments between us have not stopped since. we moved after only living there 3 months, tired of her harassment on other issues. It was not until we started arguing over other things that she began demanding money for the truck. she has mailed us a certified letter demanding the remaining money or she will take me to court. the only evidence is two handwritten receipts for the payments I already made in cash. can she do this? and do I have other options besides paying her money for my property?
