How to File a Mechanics Lien in Connecticut
Step 1 — Confirm you have lien rights in Connecticut
Connecticut's recorded rules cover general contractors, subcontractors and suppliers (Conn. Gen. Stat. § 49-34). Each of those roles has its own filing window — see Step 3. Connecticut rule detail: Record certificate of lien within 90 days of last furnishing of services or materials. Must serve copy on owner within 30 days of recording.
Step 2 — Connecticut requires no preliminary notice
Connecticut does not condition lien rights on an early notice. That removes the most common way claims are lost, but it also means the Step 3 filing date is your only checkpoint. Connecticut rule detail: Record certificate of lien within 90 days of last furnishing. Serve copy on owner within 30 days of recording. No prelim notice required.
Step 3 — Your Connecticut filing deadline
Connecticut sets the window by claimant role: • General contractors: within 90 days of your last day of work or materials. • Subcontractors and suppliers: within 90 days of your last day of work or materials. The clock runs from completion — not your invoice date. Punch-list and warranty callbacks generally do not restart it. Connecticut rule detail: File suit to foreclose lien within 1 year of recording. Lien expires after 1 year without enforcement.
Step 4 — Prepare and record the lien in Connecticut
Record in the county where the property sits, under Conn. Gen. Stat. § 49-41a. The document must identify the property, the owner of record, the amount actually owed, and what you furnished. Overstating the amount can void the claim outright. Connecticut rule detail: Written notice within 180 days of last furnishing on public works projects. No mechanic's lien on public property.
Step 5 — Serve the recorded Connecticut lien
Connecticut requires service on Town Clerk and Prime Contractor and Surety and Prime Contractor. Use Certified Mail, Return Receipt Requested and keep the receipt. In many states an unserved lien is unenforceable even though it appears on title. Connecticut rule detail: File suit on payment bond within 1 year of last furnishing.
Step 6 — Enforce before the Connecticut deadline expires
You must sue to foreclose within 1 year (filing) (40 U.S.C. § 3133(b)(2)). Miss it and the lien expires and title clears, leaving only a contract claim. Connecticut rule detail: Second-tier claimants only. No notice = no bond claim.
Retainage rules that affect your Connecticut claim
Connecticut treats retainage on its own schedule (Conn. Gen. Stat. § 42-158k), so money still held back may have a different due date than your progress billings. Connecticut rule detail: File no sooner than 90 days AND no later than 1 year.
Other Connecticut requirements that void liens
• Owner must pay prime within 30 days of invoice. Prime must pay subs within 30 days of receiving payment. Interest at 1%/month on late payments. • Retainage released within 30 days of substantial completion. 5% maximum retainage.
Frequently Asked Questions
How long do I have to file a mechanics lien in Connecticut?
Connecticut requires the lien to be recorded within 90 days, measured from completion. The exact window depends on your role — general contractors: within 90 days of your last day of work or materials.
Do I need to send a preliminary notice before filing in Connecticut?
No. Connecticut does not require a preliminary notice as a precondition to filing, which is unusual. Your filing deadline is therefore the only checkpoint protecting your lien rights.
Where do I file a mechanics lien in Connecticut?
File with the county recorder's office in the county where the property is located. Filing in the wrong county does not preserve your deadline, and re-filing in the correct county after the deadline will not save the claim.
What happens if I miss the Connecticut filing deadline?
Your lien rights are extinguished. Connecticut courts do not grant extensions for missed mechanics lien deadlines. You would be left with a breach-of-contract claim against whoever hired you, which carries no security interest in the property and is far harder to collect.
How long does a mechanics lien last in Connecticut?
Once recorded, you must file suit to enforce within 1 year (filing). If you do not, the lien expires automatically and no longer clouds the property's title.
