Minnesota Mechanics Lien Statutes: Deadlines, Venues & Citations
Where Minnesota liens are filed and enforced
A Minnesota mechanics lien is filed with the County Recorder in the county where the project sits — 120 days from last date of furnishing. Filing in the wrong county does not perfect the claim, which matters on projects that straddle county lines. Those are two different clocks against two different offices, and Minnesota claimants lose rights far more often by missing the second one than the first.
Minnesota deadlines by claimant role
For subcontractors and suppliers: Preliminary notice — 45 days from first furnishing (Minn. Stat. § 514.011); Record the lien — 120 days from last furnishing (Minn. Stat. § 514.08); file suit — 1 years from lien recorded (Minn. Stat. § 514.12); bond notice — 120 days from last furnishing (Minn. Stat. § 574.31, subd. 2(a)); file suit — 1 years from last furnishing (Minn. Stat. § 574.31, subd. 2(c)); miller act notice — 90 days from last furnishing (40 U.S.C. § 3133(b)(2)). For general contractors: Record the lien — 120 days from last furnishing (Minn. Stat. § 514.08). Every window runs from the claimant's own dates, not the unpaid invoice date.

Extendable only by written stipulation executed before the year runs, or by a certified-mail notice to the surety sent 90 days before the deadline extending it by one year, which the surety does not object to by certified mail within 30 days of receipt (subd. 2(d)). Second-tier claimants only. No notice = no bond claim. File no sooner than 90 days AND no later than 1 year.
