Minnesota: Mechanic's Lien Waiver Form and Advance-Waiver Rules
The short answer
Minnesota makes void and unenforceable a construction-contract provision requiring a contractor, subcontractor, or material supplier to waive a mechanic's-lien or payment-bond claim before being paid for the labor or materials furnished. But the statute preserves the waiver's validity for a third party that detrimentally relies on it. Minnesota prescribes no conditional, unconditional, progress, or final waiver form; an owner may withhold payment to the contractor for 120 days after completion except to the extent the contractor supplies signed waivers from notified lower-tier claimants.

This is the general rule in Minnesota. Ezel applies current Minnesota law to your specific facts and answers with citations to the statutes.
| Governing law and project scope | Minn. Stat. §§ 337.01, subd. 2; 337.10, subd. 2; and 514.07. The anti-waiver rule covers contractors, subcontractors, and material suppliers under Minnesota building/construction contracts for real property, highways, roads, or bridges; it excludes machinery/equipment maintenance or repair in production processes. |
|---|---|
| Advance or prospective waiver | A provision in or connected with a Minnesota construction contract requiring waiver of a mechanic's lien or payment-bond claim before the person is paid is void and unenforceable. A third party that detrimentally relies on the waiver remains protected (§ 337.10, subd. 2). |
| Statutory form requirement | No statutory conditional, unconditional, progress, or final form and no mandatory wording. Section 514.07 requires signed lower-tier lien waivers to release the owner's withheld payment but supplies no form. |
| Waiver types and payment stage | No statutory waiver-type labels. Section 337.10 sets the before-payment validity boundary; § 514.07 recognizes signed waivers from lower-tier claimants as the basis for the owner to pay the contractor before the 120-day post-completion withholding period ends. |
| Payment and effectiveness | A required lien/bond waiver is void before the claimant is paid for the labor or materials furnished. Section 514.07 ties owner payment to signed waivers from persons who furnished labor, skill, or material and gave the required subcontractor notice; neither section states a cleared-check or partial-payment rule. |
| Required contents, exceptions, and through date | No statutory claimant, owner, project, property, amount, check, through-date, retainage, extras, change-order, or disputed-claim fields. The § 514.07 document must be a signed waiver of the lower-tier person's mechanic's-lien claim. |
| Rights released and reserved | Section 337.10 protects both the mechanic's-lien right and a payment-bond claim from required prepayment waiver. Section 514.07 concerns mechanic's-lien claim waivers; neither section prescribes release or reservation language for contract, delay, extras, retainage, or other claims. |
| Signature, authority, notary, and format | Section 514.07 requires the waiver to be signed by the person who furnished labor, skill, or material and gave the required notice. No statutory printed-name, title, agent-authority, notarization, warning, type-size, attachment, delivery, or electronic-form rule is stated. |
| Noncompliance, remedies, and transition traps | A prohibited before-payment contract provision is void and unenforceable, but that rule does not affect waiver validity for a third party that detrimentally relies on it. The owner may withhold enough to meet lien demands and need not pay the contractor until 120 days after completion except to the extent signed waivers are furnished (§§ 337.10, subd. 2; 514.07). |

Requirements one by one
A construction contract cannot require waiver before payment
Minn. Stat. § 337.10, subdivision 2 covers contractors, subcontractors, and
material suppliers. A provision contained in or executed in connection with the
construction contract is void and unenforceable if it requires the person to
waive either the mechanic's-lien right or a payment-bond claim before being paid
for the labor or materials furnished.
Third-party detrimental reliance survives the ban
The same subdivision ends with an exception:
This provision shall not affect the validity of a waiver as to any third party
who detrimentally relies upon the waiver.
The waiver can therefore be void and unenforceable as a prohibited contract
requirement while still producing consequences for a third party that changed
position in reliance on it.
Signed lower-tier waivers can release owner-held payment
Minn. Stat. § 514.07 lets the owner withhold enough of the contract price to meet
lower-tier lien demands. The owner is not required to pay the contractor until
120 days after completion, except to the extent the contractor gives the owner
signed lien waivers from persons who supplied labor, skill, or materials and
gave the required subcontractor notice.
The statute prescribes no waiver text, through date, amount field, exception
line, warning, or notarization.
What trips people up
The third-party exception is part of the statute. A claimant cannot assume a
prohibited prepayment waiver is harmless once someone else has detrimentally
relied on it.
The owner-payment waiver is signed by the lower tier. Section 514.07 refers
to waivers signed by the people who furnished labor, skill, or material and gave
notice—not merely a blanket certification signed by the prime contractor.
The 120 days is an owner-withholding period, not a waiver deadline. It does
not create a statutory progress/final form or a 120-day period for signing one.
Common questions
Can a Minnesota subcontract require a lien waiver before payment?
No. Section 337.10, subdivision 2 makes the required lien-or-bond waiver void and
unenforceable before the claimant is paid.
Does Minnesota require conditional or unconditional waiver forms?
No. The statutes prescribe no payment-stage waiver form or mandatory wording.
Can an owner hold the contractor's payment while lower-tier liens remain?
Yes. Section 514.07 permits withholding and allows earlier payment to the extent
the contractor furnishes the owner signed waivers from the notified lower-tier
claimants.
