Recording and enforcing a Minnesota lien

Recording the lien

Record with the county recorder where the property sits. 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 promptly after recording. To keep the lien alive it must be enforced by lawsuit within 1 year after last furnishing labor or materials.

Wrongful lien exposure

Minnesota 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 Minnesota

Direct contractor notice: must include statutory lien notice in written contract; if no written contract, deliver personally or by certified mail within 10 days after work is agreed upon (Minn. Stat. §514.011 subd. 1). Subcontractor/supplier notice: must be given personally or by certified mail within 45 days after first furnishing (Minn. Stat. §514.011 subd. 2), subject to statutory exceptions (e.g., certain >4-unit residential and certain >5,000 sq ft nonresidential improvements). Lien statement: lien ceases 120 days after last work/materials unless within that period the lien statement is filed and a copy served personally or by certified mail on the owner/agent or person who contracted (Minn. Stat. §514.08 subd. 1). Statement must be verified by oath and include first/last furnishing dates and acknowledgement of service and, if applicable, §514.011 notice (Minn. Stat. §514.08 subd. 2). Enforcement: must commence action (complaint/answer) within 1 year after the date of the last item stated in the recorded lien statement; lis pendens absence after that year is conclusive as to bona fide purchasers (Minn. Stat. §514.12 subd. 3).
