I was asked to design a website. I met with the client (1 hour), took photos and send 2 preliminary drafts of designs. He paid me $50. Two weeks after our meeting, my daughter ended up in the hospital for 2 months and I dropped everything I was working on and took care of her. After she was discharged from the hospital, I was at home and got a letter from him stating that he had spoken with the state's attorney and I had to pay him the $50 plus $40 for "damages/income lost". I had a lot to catch up on so I just sent the $90. This was early this year. Yesterday I got a warrant to collect a debt from him for $90 and court costs. Looking over my records, he has never tendered the check I sent months ago. What should I do? We had no formal contract.
