Minnesota Lien Deadlines for Material Suppliers
Material suppliers in Minnesota have specific rights to file a mechanics lien if they aren't paid. However, Minnesota law requires strict adherence to notice and filing deadlines. If you miss a deadline by even one day, your lien rights may be extinguished forever. This guide outlines the critical steps for suppliers to secure their payment rights.
Public date calculations cover Florida and Kansas. Minnesota dates require qualified review.
Risk context
Minnesota is High Risk for Suppliers
Minnesota requires both recording and service of the lien statement within the preservation period. A timely filing alone is insufficient. Notice duties also depend on who hired the supplier and the property's use, size and ownership.

Scroll sideways to see all deadline details.
| Deadline Type | Timing | Details |
|---|---|---|
| Lien Recording and Service | 120 days after the claimant's last furnishing | Record the statement with the county recorder, or registrar of titles for registered land, and serve a copy personally or by certified mail on the owner, authorized agent or other recipient specified in §514.08. Complete both steps within the period. |
| Enforcement Deadline | 1 year after the last item stated in the recorded claim | Assert the lien by complaint or answer within that year. Party joinder and notice of lis pendens also matter; filing the lien does not start a new one-year clock (§514.12). |
| Indirect Supplier Notice | Generally 45 days after first furnishing | A supplier without a direct owner contract must give the statutory notice to the owner or authorized agent by personal delivery or certified mail, unless an exception applies (§514.011). |
| Direct-Owner Notice | Contract notice, or 10 days after agreement in the qualifying unwritten-contract case | The 45-day rule does not apply to a direct owner contract. A supplier that hires or will hire subcontractors or material suppliers may instead owe the owner-contract notice under §514.011 subdivision 1. |
| Notice Exceptions | Property and ownership facts control | Exceptions include specified common control, wholly residential improvements with more than four family units, and qualifying nonagricultural, nonresidential improvements meeting the statutory 5,000-square-foot conditions. A commercial label alone does not establish an exception. |
| Calendar Rules | Exclude the first day; omit a final Saturday, Sunday or legal holiday | Apply §645.15 and verify any office-specific holiday treatment before relying on an adjusted endpoint. |
| Statutes | Governing statutes | Minn. Stat. §514.011, §514.08, §514.12, and §645.15; also §§514.01 and 514.13. |
Supplier pitfalls
Common Supplier Mistakes in Minnesota
Missing the 45-day Preliminary Notice
First determine whether the indirect 45-day notice applies or a statutory exception is established. Direct-owner suppliers must separately check their own subcontracting and contract-notice duties. Missing notice or disputed compliance needs legal review.
Recording without serving the statement
The same 120-day period covers recording and service. Keep evidence of both; do not assume the recorder sends the owner's copy for you.
Starting the enforcement clock at recording
The one-year limit runs from the last item of the claim stated in the lien statement. Have counsel address the complaint or answer, necessary parties and lis pendens within the applicable period.

Common questions
Frequently Asked Questions
Does every Minnesota supplier owe a 45-day notice?
No. That rule generally applies to suppliers without a direct owner contract, subject to statutory exceptions. Direct-owner suppliers may have a different contract-notice obligation when they hire others.
Is recording within 120 days enough?
No. Section 514.08 also requires timely service of a copy by an authorized method within that period.
How long do I have to enforce a Minnesota lien?
Section 514.12 sets a one-year limit from the last item stated in the recorded claim, with procedural requirements for asserting the claim, joining parties and recording lis pendens.
