Did some work for a guy few weeks ago. 3 people most of the day there. All kinds of work from landscaping, lawn trimming, edging, tree trimming etc. Writes me a letter to let me know he's not going to pay. He decided it was too much. Told me if I want my money I need to hire an attorney. This guy is in his late 80's or early 90's. I didn't have a contract, always done my work on a handshake. Bad thing is, I have done work for this guy for 7 or so years and never had a problem with him before. I did his snow every winter and did his mowing and other small landscaping every year also. No idea where this came from. Not sure if I should just turn it to collection or hire a lawyer and put a lien on his house if I can even do that. What have some of you others done in this situation?
