I purchased a vehicle from my ex boyfriends mom. We agreed upon $4500 ( part of that was to repay his debt to her). We signed an agreement (not notarized) and I have been making payments on it but did miss a couple, totalling $375.00. About a month after we signed the agreement she signed over the title to me with a purchase amount of $800.00 on it,in her hand writing. Her son and I broke up and she is upset over this and I am still sending her money for the truck. I was handed a letter at work today from her daughter in law, stating that she is demanding the truck back or the remainder of the loan. Can she just come pick up the truck without court papers or a lien on the vehicle?
