Connecticut Mechanic’s Lien

Select a State

Below is an overview of the preliminary steps for filing a mechanic’s lien in the state of Connecticut.


  • Upfront Notice: BICA sends a Courtesy Notice.
  • Follow-up Notices (if not paid):
    • Notice of Intent:
      • A Notice of Intent to Claim a Lien must be served within 90 days of your last delivery.
      • Notice must be served by “any indifferent person, state marshal or other proper officer”.
      • Note that this is the same deadline as for filing the Certificate of Lien.


  • Same handlings as for Commercial jobs.


  • Upfront Notice: BICA sends a Courtesy Notice.
  • Follow-up Notices:
    • Notice of Claim (Notice of Non-Payment):
      • If you are not paid within 30 days of the date the Contractor or Subcontractor you are working for received payment for your services, you can send this notice.
      • If you are then not paid within 10 days of receipt of the notice, the non-paying party becomes liable for the amount owed, plus 1% interest per month.
      • You may also demand that the amount claimed, plus interest, be placed in an escrow account in the state.
        • BICA includes this demand in our notice.
        • If non-paying party fails to set up the escrow account, and you are found to have substantially performed the work according to the terms of employment, then the non-paying party will be required to pay your attorney fees.
      • This notice is available on the BICA member portal.
  • Notice of Claim on Bond:
    • This notice must be sent to the Surety (and copy to the Contractor) within 180 days of your last delivery on the job.
    • The first date you can make this claim against the bond varies:
      • It is 90 days after the Contractor or Sub-contractor received payment—if you were included on a paid requisition submitted to the awarding authority, or on an estimate prepared by the awarding authority.
        • For example, you may make claim 60 days after the payment was due, which was 30 days after the non-paying party received payment.
      • If not included on a requisition or estimate, it is 60 days after your last delivery.
    • This notice is available on the BICA member portal.
