We did not have a contract with him and paid in full the verbalized amount. He did a terrible job and he requested more money to fix what we asked for so we declined and fixed them ourselves. We did have a contractor for our new contruction that has said will act as witnesses to prove the amount. We have nothing in writing as a matter of fact-quote, invoices on materials, etc but we do have all our checks used to pay. So far he has not filed to foreclose on the lien but what can we do to defend ourselves and end this quickly?
