An unlicensed contractor in California was paid by a private homeowner to do concrete work for approximately $25,000. They started work on 12/19/2017 and we fired him for horrible work quality about three weeks later on or about January 10, 2018. We retained another concrete company who repaired the bad work and then poured and finished the job completely on Jan 19, 2018. I was never served a preliminary notice but on 12/26, 2018 (over 300 days after the project was completed) I received a Claim of Mechanics Lien for $50,000. We paid this guy a total of over $18,000 and ended up paying another $10,000 or so to a licensed concrete professional to finish this work. The claim for $50,000 has absolutely no basis whatsoever, the guy was unlicensed, we never received preliminary notice and the Claim of Mechanics Lien was sent to me over 300 days after the work was complete. Finally, I know for a fact that the lien has not yet been filed because we just refinanced the home and the title was perfectly clean as of a week ago. Can I prevent this guy from filing the Lien by contacting the Santa Barbara County recorders office and give them these facts? This is a shake down of epic proportions: the guy even listed all kinds of work that he NEVER did and was never contracted to do; he literally just made stuff up and put it onto the Lien. What can we do to get ahead of this thing and stop him from filing this fraudulent lien? Thank you SO much!!!
