⭐ How to File a Connecticut Mechanics/Construction Lien (Step-By-Step)

Connecticut Construction Lien

Follow these steps to file a Connecticut mechanics lien and make sure you’re taking the right actions to protect your payment rights.

Step 1 —Serve the Notice of Intent to Claim a Lien


In Connecticut, every contractor and supplier, without exception, must serve a Notice of Intent to Claim a Mechanics Lien in order to preserve lien rights. This requirement applies equally to general contractors, subcontractors, suppliers, and design professionals, regardless of contract tier or project type.


The Notice of Intent must be served on the property owner within ninety (90) days of the claimant’s last furnishing of labor, materials, or services. This deadline is strictly enforced, and failure to properly serve the notice completely eliminates the right to file a mechanics lien.


Connecticut law allows the Notice of Intent to be served using the following methods:

  • Registered mail, return receipt requested

  • Certified mail, return receipt requested

  • Personal service, in the same manner as service of civil process

Step 2 — Prepare the Connecticut Mechanics Lien Claim


Once payment issues arise and work is complete, the next step is preparing the Connecticut Mechanics Lien Claim. This document formally asserts your claim against the property and must strictly comply with Connecticut’s statutory requirements.


The lien must clearly identify:

  • Claimant’s legal name and address

  • Property owner’s name

  • Hiring party

  • Legal description of the property

  • Description of labor or materials furnished

  • Amount unpaid and claimed

  • Last date of furnishing
