Where Connecticut liens are filed and enforced

A Connecticut mechanics lien is filed with the Town Clerk in the county where the project sits — 90 days from completion. Filing in the wrong county does not perfect the claim, which matters on projects that straddle county lines. Those are two different clocks against two different offices, and Connecticut claimants lose rights far more often by missing the second one than the first.

Connecticut deadlines by claimant role

For general contractors: Record the lien — 90 days from last furnishing (Conn. Gen. Stat. § 49-34). For subcontractors and suppliers: Record the lien — 90 days from last furnishing (Conn. Gen. Stat. § 49-34); file suit — 1 years from lien recorded (Conn. Gen. Stat. § 49-39); bond notice — 180 days from last furnishing (Conn. Gen.

Interest at the contract rate or § 37-3a from the date the notice of claim was served; fees to either party where a claim, denial or defense lacked substantial basis (§ 49-42(a)(2)).
