I sold a computer to a previous customer of mine for $550 with a mouse, keyboard and monitor. He payed me $50 for getting the parts together and promised me the rest when it was built and delivered to him. We never signed any contract because I worked with him and people said he was a nice guy. A month and a half later, I still can't get in touch with him. I do have taped conversations with his friends admitting he owes me $500. If I went to the court with this, what are my chances of winning that case with the proof I have now? His roommates said I could just come by tomorrow, use their key and just take the computer. I don't know if that is legal or not. But, I just want to know what my options are/my chances in court with the proof I have.
