Minnesota mechanics lien deadlines

3 deadlines NoticeGuard models for Minnesota: what each one counts from, the statute it was read from, and the statute text.

Information, not legal advice. This app reports what the statute says and cites the section it read. It is not legal advice, it does not file anything for you, and it does not tell you what to do.
Verify with the statute or an attorney. Statutes change, and courts reinterpret them. Every deadline in this app comes from a statute read on the date shown next to its citation - that snapshot can go out of date. Missing a mechanics lien deadline can extinguish your claim permanently, so confirm any deadline you are relying on with an attorney licensed in that state before you act on it.
Data verified: statute text retrieved 2026-09-21 (each citation below carries its own date). Rule data from the NoticeGuard app, source commit 22f9300.

Each deadline, with the statute

Subcontractor's or supplier's notice to owner

Delivered personally or by certified mail to the owner, counted from the day this claimant first furnished labor, skill, or materials. A necessary prerequisite to the validity of any lien claim.

What it counts from. 45 days after first furnishing (commenced work).

Applies to. Subcontractor, Supplier, Preconstruction service.

Minn. Stat. § 514.011 Subd. 2(a)
Official source · statute text retrieved 2026-09-21

“Every person who contributes to the improvement of real property so as to be entitled to a lien pursuant to section 514.01, except a party under direct contract with the owner, must, as a necessary prerequisite to the validity of any claim or lien, cause to be given to the owner or the owner's authorized agent... not later than 45 days after the lien claimant has first furnished labor, skill or materials for the improvement, a written notice...”

If the date is missed (the statute's own terms). The statute states this notice is "a necessary prerequisite to the validity of any claim or lien" - though Subd. 2(b) softens strict enforcement: a good-faith effort to comply preserves the lien unless the owner or another claimant proves actual damage from the noncompliance.

Also stated next to this deadline.

Record and serve the lien statement

Both recorded with the county recorder (or registrar of titles, or secretary of state for certain claims) AND served on the owner, counted from this claimant's own last labor, skill, material, or machinery furnished.

What it counts from. 120 days after last furnishing (last day on site).

Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service.

Minn. Stat. § 514.08 Subd. 1
Official source · statute text retrieved 2026-09-21

“The lien ceases at the end of 120 days after doing the last of the work, or furnishing the last item of skill, material, or machinery, unless within this period: (1) a statement of the claim is filed for record with the county recorder... and (2) a copy of the statement is served personally or by certified mail on the owner or the owner's authorized agent or the person who entered into the contract with the contractor.”

If the date is missed (the statute's own terms). The statute states plainly "the lien ceases" at the end of this period without both the recording AND the service - a right-extinguishing deadline covering two required acts, not one.

Also stated next to this deadline.

Commence a foreclosure action

Asserted by filing a complaint or answer, counted from the SAME last-furnishing date the recorded lien statement itself states - not from the date the lien statement was actually recorded.

What it counts from. 365 days after last furnishing (last day on site).

Applies to. Original contractor, Subcontractor, Supplier, Preconstruction service.

Minn. Stat. § 514.12 Subd. 3
Official source · statute text retrieved 2026-09-21

“No lien shall be enforced in any case unless the holder thereof shall assert the same, either by filing a complaint or answer with the court administrator, within one year after the date of the last item of the claim as set forth in the recorded lien statement...”

If the date is missed (the statute's own terms). The statute states no lien "shall be enforced... unless" asserted within this period - a hard outer bound on enforcement.

Also stated next to this deadline.

Weekend and holiday rollover

NoticeGuard does not model a weekend or holiday extension for Minnesota. The dates above are the plain count from the date you enter. Check whether a Saturday, Sunday or holiday changes your date.

About the NoticeGuard app

NoticeGuard is an app that turns a job's dates into a countdown for each statutory step, shows the statute text each date was read from, exports a calendar file (.ics) and sends reminders 14, 7 and 1 day before each deadline. It tracks and reminds; it does not file anything for you.
