Connecticut Notice of Intent to Claim a Lien & Mechanic's Lien — Conn. Gen. Stat. § 49-35 / § 49-34 / § 49-39 Filing Guide (2026)
What Is the Connecticut Mechanic's Lien Framework and How Does the Lien Workflow Operate?
Connecticut's mechanic's lien framework is Conn. Gen. Stat. ch. 847, §§ 49-33 to 49-40a. For a claimant not in privity with the owner the workflow runs in four steps: (1) the § 49-35 Notice of Intent to Claim a Lien — served on BOTH the owner and the original contractor within 90 days of ceasing work; (2) lodging the § 49-34 certificate of mechanic's lien with the town clerk within 90 days of ceasing work; (3) serving a true and attested copy of the certificate on the owner within 30 days of lodging; and (4) commencing the § 49-39 foreclosure action and recording a notice of lis pendens within one year of the recording date. The original contractor, who deals directly with the owner, skips the Notice of Intent. Connecticut is distinctive in three respects: town-clerk recording (Connecticut abolished county government in 1960 and has no county land-records office, so the certificate is lodged with one of 169 town clerks), the Notice of Intent prerequisite (a non-privity claimant who records without first serving the § 49-35 notice has no enforceable lien), and the subrogation / lien-fund cap under § 49-33 and § 49-36.
Who Must Serve a Connecticut Notice of Intent
The Notice of Intent to Claim a Lien under § 49-35 is required of claimants who furnish materials or render services but have no direct contract with the owner — subcontractors, sub-subcontractors, and suppliers below the original contractor. A non-privity claimant must serve a written Notice of Intent on BOTH the owner and the original contractor after commencing, and not later than 90 days after ceasing, to furnish materials or render services; failure to serve it within the 90-day window is generally fatal — the certificate that follows is unenforceable. The original contractor, who deals directly with the owner, does not serve a Notice of Intent, and a subcontractor whose contract with the original contractor is in writing and has been assented to in writing by the owner is also excused. The written-assent exception is narrow: it requires the owner's written assent to the subcontract, not merely the owner's knowledge that a subcontractor is on site.
Town-Clerk Recording — Connecticut's Threshold Trap
Connecticut is unlike nearly every other state: there are no county land-records offices. Connecticut abolished county government as an administrative unit in 1960, and land instruments — including mechanic's liens — are recorded at the town level. Each of Connecticut's 169 towns maintains its own land records through its town clerk, and a § 49-34 certificate of mechanic's lien must be lodged with the town clerk of the town where the property lies. (Connecticut adopted nine planning regions as county-equivalents for federal and census purposes effective 2024, but those regions are not recording offices.) A claimant that searches for a nonexistent county recorder, or that lodges the certificate in the wrong town, gets no protection from the filing. Confirming the correct town clerk — Hartford, New Haven, Stamford, Bridgeport, Norwalk, Danbury, Waterbury, Greenwich, New London, Groton, and the other towns — is the first step in any Connecticut lien filing.
§ 49-35 Notice of Intent, § 49-34 Certificate, and the § 49-39 One-Year Deadline
For a non-privity claimant, the § 49-35 Notice of Intent comes first: served on both the owner and the original contractor after commencing and within 90 days of ceasing work, by personal service or registered/certified mail. The lien is then perfected by lodging the § 49-34 certificate of mechanic's lien with the town clerk within 90 days of ceasing work — describing the premises, stating the amount claimed, naming the owner of record, and stating the date of commencement, subscribed and sworn to — with a true and attested copy served on the owner within 30 days of lodging. Under § 49-39, the lien is invalid and discharged as a matter of law unless the claimant commences a foreclosure action and records a notice of lis pendens within one year from the recording date, in the Connecticut Superior Court for the judicial district where the property lies. Both the § 49-35 Notice of Intent and the § 49-34 certificate run from the date the claimant ceased work — not the invoice date, a punch-list visit, or overall project completion.
The Connecticut Lien Fund and the Home Improvement Act
A Connecticut subcontractor's lien is a subrogation / lien-fund lien. Under § 49-33 a subcontractor's lien cannot exceed the amount the owner agreed to pay the person through whom the subcontractor claims, and under § 49-36 the aggregate of all liens cannot exceed the price the owner agreed to pay the original contractor — with the owner credited for payments made in good faith to the original contractor before receiving notice of the lien. Advance payments are not treated as good faith unless the owner gave written notice at least five days beforehand. If the owner has already paid out the contract balance before any lien notice arrives, the fund may be small or empty, which is why serving the § 49-35 Notice of Intent early preserves a larger fund. On residential work, the Home Improvement Act (§ 20-418 et seq.) and the New Home Construction Contractors Act (§ 20-417a et seq.) require a compliant written contract and registration, and noncompliance can bar enforcement of the contract and the lien that depends on it.
Filing Fees and Where to File
The § 49-34 certificate of mechanic's lien is lodged with the town clerk of the town where the property is located — one of Connecticut's 169 towns, not a county recorder. Connecticut town-clerk land-recording fees are generally a modest per-document fee (commonly in the $53–$60 range for the first page plus a few dollars per additional page), and serving the § 49-35 Notice of Intent and the attested copy of the certificate by certified mail typically runs under $15 per party. Connecticut Superior Court filing fees to commence a lien-foreclosure civil action run roughly $360, with additional costs for service by a state marshal and recording the notice of lis pendens. Total perfection-and-enforcement filing costs typically run $450–$700 before attorney fees. Confirming the correct town clerk, that any non-privity claimant served the § 49-35 Notice of Intent within 90 days, that the certificate was lodged within 90 days and the attested copy served on the owner within 30 days, that residential work meets the Home Improvement Act, and that the § 49-39 one-year deadline is calendared is the most important intake step.
Frequently Asked Questions
What is the Connecticut Notice of Intent to Claim a Lien under Conn. Gen. Stat. § 49-35?
The Connecticut Notice of Intent to Claim a Lien is a written notice, required by Conn. Gen. Stat. § 49-35, that any person other than the original contractor — typically a subcontractor, sub-subcontractor, or material supplier with no direct contract with the owner — must give to BOTH the property owner and the original contractor to preserve mechanic's lien rights. It must be served after the claimant commences, and not later than 90 days after the claimant ceases, to furnish materials or render services. The only claimants excused are the original contractor and a subcontractor whose contract with the original contractor is in writing and has been assented to in writing by the owner. For everyone else, failure to serve a proper Notice of Intent within the 90-day window is generally fatal — the certificate of lien that follows will be unenforceable. The notice is separate from, and a prerequisite to, the certificate lodged with the town clerk under § 49-34.
When must a Connecticut certificate of mechanic's lien be recorded?
Under Conn. Gen. Stat. § 49-34, the certificate of mechanic's lien must be lodged with the town clerk of the town in which the property is located not later than 90 days after the claimant has ceased to perform services or furnish materials. The certificate must describe the premises, state the amount claimed as a lien, name the person against whom the lien is being filed (the owner of record), and state the date of commencement of the performance of services or furnishing of materials, and it must be subscribed and sworn to by the claimant. A true and attested copy of the recorded certificate must be served on the owner not later than 30 days after the certificate is lodged. Connecticut records land instruments at the town level — 169 towns and no county recorders. Missing the 90-day lodging deadline or the 30-day owner-service deadline defeats the lien.
Where are Connecticut mechanic's liens recorded — town clerk or county recorder?
Connecticut mechanic's liens are recorded with the TOWN CLERK, not a county recorder. Connecticut abolished county government in 1960 and, unlike nearly every other state, has no county-level land records office. Each of Connecticut's 169 towns maintains its own land records through the town clerk, and a § 49-34 certificate is lodged with the town clerk of the town where the property lies — Hartford, New Haven, Stamford, Bridgeport, Norwalk, Danbury, Waterbury, Greenwich, New London, Groton, and so on. (Connecticut adopted nine planning regions as county-equivalents for federal and census purposes effective 2024, but those regions are not recording offices.) A claimant who tries to record at a nonexistent county office, or who lodges in the wrong town, loses the protection of the recording.
How long does a Connecticut mechanic's lien last and when must a foreclosure action be filed?
Under Conn. Gen. Stat. § 49-39, a Connecticut mechanic's lien does not continue in force for longer than one year after the lien has been perfected unless the party claiming the lien commences an action to foreclose it AND records a notice of lis pendens, both within one year from the date the lien was recorded. If the claimant does not both file the foreclosure action and record the lis pendens within that one-year window, the lien is invalid and discharged as a matter of law — no separate court order is required. The foreclosure action is brought in the Connecticut Superior Court for the judicial district where the property is located, and § 49-39 directs that foreclosure actions are privileged in respect to assignment for trial. Because the one-year clock runs from the recording date and cannot be extended by settlement talks, calendar the deadline the moment the certificate is lodged.
How does the Connecticut lien-fund (subrogation) rule limit a subcontractor's lien?
Under Conn. Gen. Stat. § 49-33, a subcontractor's lien cannot exceed the amount the owner has agreed to pay the person through whom the subcontractor claims, and under § 49-36 the aggregate of all liens may not exceed the price the owner agreed to pay the original contractor. The owner is credited for payments it made in good faith to the original contractor before receiving notice of the lien — so if the owner has already paid the general contractor most or all of the contract price before any lien notice arrives, the fund available to subcontractor liens may be small or nonexistent. Payments made in advance of the time stipulated in the original contract are not treated as good faith unless the owner gave written notice at least five days beforehand. The practical lesson: a subcontractor that serves its § 49-35 Notice of Intent early — before the owner pays out the balance — preserves a larger fund for its lien.
Does Connecticut's Home Improvement Act affect residential mechanic's liens?
Yes. Connecticut's Home Improvement Act (HIA), Conn. Gen. Stat. § 20-418 et seq., requires a written contract meeting specific statutory requirements and registration as a home improvement contractor for most residential home-improvement work. Connecticut courts have held that a contractor who fails to comply with the HIA's written-contract and registration requirements can be barred from enforcing the contract — and that bar can extend to the mechanic's lien that depends on the underlying contract. For new residential construction, the New Home Construction Contractors Act, § 20-417a et seq., imposes its own registration and contract requirements. A residential contractor or subcontractor that proceeds without a compliant written contract or without the required registration can find that even a perfectly recorded § 49-34 certificate is unenforceable.
How does Connecticut handle public works and federal projects?
No mechanic's lien attaches to public property in Connecticut. On Connecticut state, municipal, and authority public works, an unpaid subcontractor or supplier pursues a claim against the prime contractor's payment bond required by the Connecticut Little Miller Act, Conn. Gen. Stat. § 49-41, with enforcement and notice requirements under § 49-42 (a claimant without a direct contract with the general contractor generally must give notice within 180 days of last furnishing and sue within one year). On federal projects the federal Miller Act at 40 U.S.C. § 3131 et seq. preempts state lien rights — pursue the prime contractor's federal Miller Act payment bond. Connecticut's federal construction base includes Naval Submarine Base New London (Groton), the U.S. Coast Guard Academy (New London), the Abraham A. Ribicoff Federal Building and U.S. Courthouse in Hartford, the Richard C. Lee U.S. Courthouse in New Haven, the Brien McMahon Federal Building in Bridgeport, the VA Connecticut Healthcare System campuses in West Haven and Newington, and U.S. Army Corps of Engineers Connecticut River basin projects. Connecticut prompt payment is governed by § 42-158i et seq. (private) and § 49-41a (public).
