Recording and enforcing a Maine lien

Recording the lien

Record with the register of deeds for the county. Electronic recording is not generally available, so build mailing time into the deadline. The lien must be notarized. The lien claim must be sworn to under oath.

After recording

A copy of the recorded lien must be served on the property owner within 30 days of recording. To keep the lien alive it must be enforced by lawsuit within 120 days after last furnishing labor or materials.

Wrongful lien exposure

Maine has no dedicated wrongful-lien penalty statute, but an inflated or baseless lien can still be challenged and removed at the claimant's expense.

Practitioner notes for Maine

Lien certificate must be recorded in the registry of deeds within 90 days after the lien claimant last performed labor or furnished materials (10 M.R.S. §3253). A copy of the lien certificate must be given to the owner (and certain others) within 30 days after recording (10 M.R.S. §3253). Enforcement: action to enforce lien must be commenced within 120 days after last labor/materials (10 M.R.S. §3255). Because enforcement is keyed to last furnishing (not recording date), this sheet sets enforcement_trigger=last_furnish_date.
