Maine 90-Day Notice and Filing Deadlines — 10 M.R.S.A. §§ 3253–3254
Under 10 M.R.S.A. § 3253, every claimant — including general contractors — must serve written notice of the lien claim on the property owner within 90 days of last furnishing. Under § 3254, within the same 90-day period, the claimant must file a certificate of lien with the Registry of Deeds of the county where the property is located. Both the owner notice and the Registry filing must occur within 90 days of last furnishing. Failure to serve the owner notice is fatal to the lien claim regardless of whether the Registry filing was timely. Maine requires owner notice from ALL claimant tiers — general contractors are not exempt.
Maine's Critical 120-Day Suit Requirement — 10 M.R.S.A. § 3255
Maine's most distinctive and critical rule is found in 10 M.R.S.A. § 3255: a person claiming a lien must bring a civil action to enforce the lien within 120 days after the last day on which labor was performed or materials furnished. Unlike virtually every other state in the US — where claimants have 1–2 years after recording to file suit — Maine compresses the entire process into 120 days from last furnishing. A claimant who files the certificate on Day 88 has only 32 more days to commence the enforcement action in Maine Superior Court. There is no extended negotiation window after recording.
Where to File in Maine — 16 County Registries of Deeds
Maine mechanics lien certificates are filed with the Registry of Deeds of the county in which the improved property is located under 10 M.R.S.A. § 3254. Maine has 16 counties: Androscoggin (Auburn), Aroostook (Houlton), Cumberland (Portland), Franklin (Farmington), Hancock (Ellsworth), Kennebec (Augusta), Knox (Rockland), Lincoln (Wiscasset), Oxford (South Paris), Penobscot (Bangor), Piscataquis (Dover-Foxcroft), Sagadahoc (Bath), Somerset (Skowhegan), Waldo (Belfast), Washington (Machias), and York (Alfred). Filing in the wrong county creates no valid lien.
No Extended Post-Filing Enforcement Window
Unlike states where mechanics liens stand on title for 1–2 years giving claimants time to negotiate, Maine's 120-day suit deadline from last furnishing eliminates any extended post-filing window. A claimant must be prepared to file suit by Day 120 if payment has not been received. Practically, claimants should retain Maine construction counsel no later than Day 100 — before the 120-day mark — to allow adequate time to prepare and file the complaint. The Mechanics Lien Management State System tracks all three of Maine's deadlines: Day 90 notice to owner, Day 90 Registry filing, and Day 120 suit deadline.
