To file a mechanic’s lien in Connecticut, you prepare a sworn certificate containing the property description, the amount owed, the owner’s name, and the date you started work; record it with the Town Clerk in the town where the property sits within 90 days of your last day of work or delivery; and serve a true and attested copy on the owner within 30 days after recording. Subcontractors and suppliers without a direct written contract with the owner have an extra step first. Miss any deadline or leave out any required element, and the lien is invalid.
Confirm You Have the Right to File
Under C.G.S. § 49-33, anyone with a claim over ten dollars for materials furnished or services rendered in the construction, raising, removal, or repair of a building, or in the improvement of a lot, can claim a lien against that property.1Connecticut General Statutes. Connecticut Code 49-33 – Mechanic’s Lien The work must have been done under an agreement with the owner, by the owner’s consent, or by someone the owner authorized to procure the labor or materials. General contractors, subcontractors, material suppliers, and laborers all qualify. If the work was done under a lease, the lien attaches to the leasehold interest rather than the fee title.
If you contracted directly with the owner, you can skip to the certificate itself. If you did not, read the next section first.
Subcontractors and Suppliers: Serve a Notice of Intent First
If you are not the original contractor and do not have a written contract with the general contractor that the owner has assented to in writing, C.G.S. § 49-35 requires you to serve a written notice of intent on both the property owner and the general contractor before recording a lien.2Connecticut General Statutes. Connecticut Code 49-35 – Notice of Intent, Liens of Subcontractors and Materialmen The notice must go out after you begin furnishing materials or services and no later than 90 days after you stop. It must state that you have furnished or begun furnishing materials or services and that you intend to claim a lien.
Service follows the same method used later for the lien certificate: hand delivery by a proper officer or an indifferent person (someone with no stake in the dispute). If the owner is out of state, alternative methods such as certified mail or service on a registered agent may be acceptable. Keep the endorsed return of service. Skipping the notice or serving it late destroys your lien rights entirely, so treat the 90-day window as fixed.
What the Certificate Must Contain
C.G.S. § 49-34 lists the required contents of a valid certificate. Every element matters; leave one out and the lien can be thrown out.3Connecticut General Statutes. Connecticut Code 49-34 – Certificate of Lien to be Recorded and Notice Given to Owner
- A legal description of the premises. A street address alone is not enough. Use a metes-and-bounds description or reference the volume and page of a previously recorded deed in the town land records.
- The amount claimed. State the dollar amount you are actually owed. The statute requires you to affirm the amount is “justly due, as nearly as the same can be ascertained.”
- The name of the property owner, exactly as it appears in the land records.
- The date you first performed services or furnished materials for the project.
- A sworn statement, subscribed and sworn to before a notary public or other official authorized to administer oaths.
The statute lists the commencement date but does not explicitly require the cessation date. The cessation date drives your 90-day recording deadline, and most standard forms include a field for it. Filling it in strengthens your documentation if the lien’s timeliness is later challenged.
State the Amount Accurately
Claim what you are owed, not an inflated figure meant as leverage. Connecticut courts look at whether the amount reasonably reflects the debt, and a grossly overstated lien invites litigation and weakens your position in any later foreclosure.
Notarization
The certificate is not valid without the sworn-and-subscribed formality. Bring it to a notary unsigned, sign in the notary’s presence, and have the notary apply their seal and signature. Without this step, the Town Clerk cannot accept the document for recording.
Where to Get the Form
Connecticut does not publish a single mandatory template. Standardized certificate forms are available from legal stationery suppliers and some Town Clerk offices, and attorneys and construction law form sets have their own. Whichever form you use, confirm it includes fields for every element required by § 49-34. Cross-check the property description against the land records before you fill anything in. A mismatch between the certificate and the recorded deed is one of the most common reasons liens are challenged.
Record the Certificate With the Town Clerk Within 90 Days
File the notarized certificate with the Town Clerk in the town where the property is located within 90 days after you last performed work or delivered materials.3Connecticut General Statutes. Connecticut Code 49-34 – Certificate of Lien to be Recorded and Notice Given to Owner This deadline is absolute. If day 91 arrives without the certificate in the land records, your lien right is permanently gone.
Recording fees are set by C.G.S. § 7-34a. The combined statutory fees total $70 for the first page and $5 for each additional page.4Connecticut General Assembly. Connecticut Code 7-34a – Fees Bring the certificate in person if you can, or confirm the Town Clerk’s mailing and payment procedures well in advance. A mailed submission that arrives after the 90-day window closes is worthless.
Serve the Owner Within 30 Days After Recording
Recording is only half the job. Within 30 days after the certificate is lodged with the Town Clerk, you must serve a true and attested copy on the property owner.3Connecticut General Statutes. Connecticut Code 49-34 – Certificate of Lien to be Recorded and Notice Given to Owner Service must be made in the same manner as the § 49-35 notice: by a proper officer or indifferent person who can provide proof of delivery.
The person who serves the copy will produce a return of service endorsement showing the date, time, and method of delivery. Hold onto it. It is your proof that you met the 30-day requirement, and you will need it if you later foreclose. An otherwise valid lien becomes unenforceable if the owner is never properly served.
Keep the Lien Alive: Foreclose Within One Year
A recorded mechanic’s lien does not last forever. Under C.G.S. § 49-39, the lien expires and is automatically discharged as a matter of law unless you commence a foreclosure action within one year of the recording date.5Connecticut General Statutes. Connecticut Code 49-39 – Time Limitation of Mechanic’s Lien, Action to Foreclose Privileged Commencing the action means filing a complaint (or cross-complaint or counterclaim) and recording a notice of lis pendens on the land records in the same town. Both steps must happen within the one-year window. If the owner has filed an application to discharge or reduce the lien under § 49-35a, you get an alternative deadline of 60 days after the final disposition of that application, including any appeal, whichever is later.
Filing the certificate can feel like the hard part, but letting the one-year clock run out is where many lienors lose their leverage. When the deadline passes, the lien vanishes from the title and you are back to an unsecured debt.
Advance Lien Waivers Are Void
If a contract clause purported to waive your mechanic’s lien rights before the work was performed and paid for, that clause is unenforceable. Under C.G.S. § 42-158l, any contract provision or periodic lien waiver that tries to waive the right to claim a mechanic’s lien, or to make a claim against a payment bond, for services or materials not yet performed and paid for is void as against public policy.6Connecticut Judicial Branch. Mechanic’s Liens in Connecticut – A Guide to Resources in the Law Library A waiver signed at the same time as or after you receive payment for specific work is valid; one signed in advance as a condition of getting the job is not.
