Understanding the Prelien Process on Construction Projects in Connecticut by Role

Connecticut does not require a preliminary notice before furnishing labor or materials. However, claimants (excluding general contractors) must serve a Notice of Intent to Lien within 90 days of last furnishing. A lien certificate must be recorded within this time and then served on all property owners within 30 days of recording.

Mechanic's Liens in Connecticut

All lien claimants must file a Certificate of Mechanics Lien in the town where the property is located within 90 days after the last furnishing of labor or materials. The lien must be served on the owner within 30 days after recording. Foreclosure must be commenced within one year. A Notice of Intent to Lien is often served concurrently with the lien certificate to meet notice obligations for lower-tier claimants.

Bond Claims in Connecticut

On public projects, mechanic's lien rights are typically replaced by bond claim rights. Bond claim notice and enforcement timelines can vary by project type and bond language, so coordinate with your construction attorney to confirm the correct deadline and required notice path.

Construction Lien Waivers in Connecticut

Required format: Connecticut does not require any specific statutorily required verbiage to be valid but be sure to check with your constuction attorney and consult any relevant state statutes.

Required notarization: Connecticut does not require waivers to be notarized.

Connecticut does not impose a statutory waiver format. Waivers are enforceable as contracts and should be reviewed to ensure they do not inadvertently waive rights before payment is received.
