I loaned my boyfriend a couple thousand dollars about a year ago so he could buy a new car. I wrote him a check but didn't include any clause saying he would have to pay me back. I asked him to start paying me back in small amounts. He then said he wanted to break up and we are no longer together. I was thinking of taking him to court, but I only have the receipt from the car dealer and the car is in his name. Can I win my money back if I take him to court?
