How to Fill Out and File a Minnesota Mechanics Lien Form

To file a Minnesota mechanics lien, you complete the state’s Statement of Mechanics Lien form (Form 40.1.1 for individuals or Form 40.1.2 for business entities), sign it before a notary, record it with the county where the property is located, and serve a copy on the property owner. All of that must be done within 120 days of the last day you supplied labor or materials to the project. Miss that window and the lien right is gone for good.¹ The blank forms are published by the Minnesota Department of Commerce as part of its Uniform Conveyancing Blanks.²

Which Form to Use

Use Form 40.1.1 if you are filing as an individual. Use Form 40.1.2 if the claimant is a business entity such as an LLC or corporation. Both are free downloads from the Department of Commerce’s Uniform Conveyancing Blanks page. The two versions ask for the same statutory information; only the signature and verification blocks differ.

Check the Two Deadlines Before You Start

Two clocks matter, and one of them may already be running.

The first is the 120-day recording and service deadline. It begins on the last date you supplied labor or materials to the project and applies to every claimant.¹

The second applies only if you were hired by someone other than the property owner, such as a subcontractor or supplier working under a general contractor. In that case, you had to give the owner a written pre-lien notice within 45 days of the first date you provided labor or materials. The notice must include your name and address, the name of the contractor who hired you, and a description and estimated value of what you’re providing. Deliver it personally or by certified mail.³⁴ If that 45 days has already passed and you didn’t send the notice, the lien statement won’t save you. If you’re still within the window, send it before you do anything else.

What the Statement Must Contain

Section 514.08 lists nine items the lien statement must include, and the Uniform Conveyancing Blanks form is built around them.¹ Work through the form in order:

A statement of intention to claim and hold a lien, together with the exact dollar amount owed. Use the actual unpaid balance for your work. Overstating the amount can expose you to a damages claim and attorney fees from the owner.
A description of what the debt is for (labor, skill, materials, or machinery) and the improvement it went into. Something specific like “installed HVAC system in new single-family residence” is far more useful than “construction work.”
The names of the parties: your name (the claimant) and the person or company you contracted with. If you’re a subcontractor, that’s the general contractor, not the owner.
The first and last dates you contributed labor or materials. Both dates are critical. The 120-day filing clock and the one-year enforcement clock both run from the last date.
The legal description of the property. A street address alone is not enough. You need the lot and block or metes and bounds description that identifies the parcel with reasonable certainty. Pull it from a prior deed, the county assessor’s records, or a title commitment. Do not copy the shortened description off a property tax statement.⁵
The name of the owner of record at the time you sign, based on your best available information. County property records or a call to the assessor will confirm it.
Your post office address as the claimant. Omitting this specific field does not invalidate the lien, but there’s no reason to leave it blank.¹
An acknowledgment that a copy of the lien must be served on the property owner within the 120-day window. This language is preprinted on the form and must stay.
Confirmation of the 45-day pre-lien notice if you were required to give one. A general contractor who dealt directly with the owner can note that no such notice was required.

You do not need to include the owner’s Social Security number or taxpayer identification number.¹

Sign and Notarize the Form

The statement must be verified under oath by someone with personal knowledge of the facts, which means the claimant or a company officer signs it in front of a notary public.¹ The notary block needs the date, the state and county where you signed, the notary’s legible signature and seal, and the notary’s commission expiration date.⁵

If getting to a notary in person is inconvenient, Minnesota permits remote online notarization through an approved audio-video platform, so long as the notary is physically located in Minnesota. A remote notarization has the same legal effect as one done in person.⁶ Read every field once more before you sign. Providing false information under oath can lead a court to void the lien entirely.

Record the Statement with the County

File the notarized statement with the county where the property is located, within 120 days of your last day of work or last delivery. No extensions exist.

Where inside that county depends on how the property is titled. Most Minnesota land is abstract property, which files with the County Recorder. Torrens (registered) property, which has a Certificate of Title under court supervision, files with the Registrar of Titles.⁵ In many counties the same office handles both, and the recorder’s staff can tell you which system applies if you’re unsure.⁷

The recording fee is $46 statewide, set by statute and the same in all 87 counties.⁸ You can file in person, by mail, or electronically where the county offers e-recording. Ask for a stamped copy or recording receipt. That receipt is your proof of the exact filing date if the 120-day deadline is ever challenged.

Serve a Copy on the Property Owner

Recording is only half the requirement. A copy of the recorded statement must also reach the property owner, the owner’s authorized agent, or the person who contracted with the general contractor, and it must get there within the same 120 days.¹

Two service methods are allowed: personal delivery or certified mail. If you use certified mail, add return receipt service (USPS Form 3811, the green card) so the postal service captures the signature, delivery address, and date. Keep the signed card. A photograph of it is not accepted as equivalent proof, though an electronic return receipt PDF carries the same weight as the physical card.

Once service is complete, write a brief affidavit describing how and when you delivered the copy. Keep that affidavit with the return receipt in your file. If the owner later disputes service, those two documents together prove you met the requirement.

What Filing the Lien Does Not Do

Recording and serving the statement preserves your claim, but it does not by itself get you paid. To force payment or a sale of the property, you have to file a lien foreclosure lawsuit within one year after the last date listed on your recorded statement. File the complaint with the district court administrator in the county where the property sits, and name every party you want bound by the judgment inside that same year.⁹

If the year passes without a lawsuit, the lien becomes unenforceable. For Torrens property, the Registrar of Titles will stop carrying the lien forward to new certificates once the year expires with no notice of pending litigation on file.⁹ Many claimants file correctly, assume the cloud on title alone will produce payment, and let the enforcement deadline slip.

When the Form Does Not Apply

Mechanics liens cannot attach to property owned by the federal government. If you’re unpaid on a federal construction project in Minnesota, your remedy is a claim against the general contractor’s payment bond under the federal Miller Act, not a Minnesota lien filing.
