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

Maine Construction Lien

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

Step 1 — Determine Your Contract Tier


This controls your path in Maine:

  • Direct contract with owner (GC/prime): you may proceed straight to enforcement (lawsuit) within 120 days, without the 90-day recorded claim requirement.

  • No direct owner contract (subs/suppliers): you typically must record the lien claim within 90 days and mail the owner a copy, then enforce by lawsuit within 120 days.

Step 2 — Lock Your “Last Furnishing” Date


Identify the last date you actually furnished lienable labor/materials/services. This date drives:

  • the 90-day subcontractor claim filing window (if applicable), and

  • the 120-day lawsuit deadline (for everyone).

Step 3 — Prepare the Maine Claim of Lien (Lien Statement)


For claimants who must record a Maine lien claim, the recorded statement must be:

  • The name of the lien claimant

  • The name of the property owner

  • A description of the property sufficient for identification

  • The amount claimed

  • A statement of the labor or materials provided

  • The date of last furnishing

  • be subscribed and sworn (verified).

Step 4 — Record the Lien + Mail the Owner a Copy


If you don't have a contract directly with the owner, record your Maine claim of lien in the Registry of Deeds where the property is located within 90 days.


Then serve a copy to the owner:

  • Service method: mail, return receipt requested or personal service 

  • Proof: obtain a post office certificate of mailing (statutorily conclusive proof of receipt).

Step 5 — Enforce Your Main Claim of Lien (File Suit)


File a foreclosure/enforcement action in Maine court within 120 days of last furnishing.
If you are a sub/supplier without an owner contract, be mindful of the statutory rule delaying when the owner can be served after filing.
