Connecticut Mechanic's Lien Guide

Not required, but it is recommended to send a Preliminary Notice at the start of the project to notify parties of potential lien rights.

If the general contractor filed a 15-day affidavit, claimant must serve a Notice of Intent to Claim a Lien on the owner and general contractor at some point within the 90-day period after you last furnished labor or materials and before you file the lien certificate. It is best practice to send by day 60 of claimant's last day in order to give ample warning of a lien claim. A lien is due 90 days from the claimant's last furnishing, and the Notice of Intent needs to be sent to the owner and general contractor prior to the lien recording (if 15-day affidavit was filed). If you are not sure the affidavit was filed, you can still send the Notice of Intent to be safe.

Must file a "Certificate of Mechanic's Lien" with the town clerk in the town where the property is located within 90 days after you have ceased to furnish labor, materials, or services. You must then serve a true and attested copy of that lien certificate upon the owner and general contractor within 30 days of its recording. Enforcement must be initiated within 1 year of lien filing. Mechanic's liens cannot be extended in Connecticut.
