My sister's ex boyfriend is nuts!! He has been threatening her with small claims court for a while now. All because he helped her, while they were still together, get a 4 wheeler, by getting the loan in his name; but she's paid every penny of it. It's only been late once, that was last month, but it did get paid. She has proof of every payment she's made. He told her earlier this week that he wanted the 4 wheeler back and she said that he can have it he gave her the money she's paid so far, he told her no and is taking her to court. My question is, what should she do? What do you think could happen in the case?
