I had a "friend of a friend" install our new air conditioning. He has his own a/c business. We had a verbal agreement that we would give him a check upfront for the work, however he needed to wait 4 days to actually deposit the check. We were waiting for a paycheck to be deposited in our account. He agreed, yet went to the bank and deposited the check the next day. He thought it would take a few days to clear. He was wrong, and the check bounced. We have offered to write a new check. But he will not respond. I fear he is consulting his attorney. Can he take us to court, even though we are still offering to pay?
