My question involves small claims court in the state of: Delaware
I am partners in a used car dealership. I sold a car last October. The customer left a deposit, and was coming back in a week to pay it off. He made excuses and I gave him 30 days to p[ay it off. He did make one payment about a month later. He came back in march and wanted his money back(I had just sold the car). I told him it was nonrefundable, but offered half back 350. He said no.
He called and wanted my full name so he could sue (claimed he was at the court)
I refused to give him my name.
I have a couple of questions. My business is a sole proprietorship.
1) if he files suit, can he sue me personally? It happened once before, and I lost.
2) if he does not have or lost his paperwork do I (should I) produce the bill of sale?
I don't think he has any case at all, but Delaware small claims is more informal and does not follow strict legal rules.
