Kansas Mechanics Lien Statute: Filing, Priority, and Enforcement

A Kansas mechanics lien lets a contractor, subcontractor, or material supplier secure payment for work on a property by filing a verified claim against the real estate itself. The right comes from K.S.A. 60-1101 and 60-1103, and it applies to anyone who furnished labor, equipment, materials, or supplies for an improvement to real property.¹ The deadlines are short, the rules differ by tier, and residential jobs carry extra notice requirements that void otherwise valid claims.

Who Can File

Kansas splits potential claimants into two groups, and the group you fall into decides which statute governs your filing.

If you contracted directly with the property owner, or with the owner’s trustee, agent, or spouse, you file under K.S.A. 60-1101. This is the path for a general contractor or anyone the owner hired directly.¹

If your contract was with the general contractor or another subcontractor, you file under K.S.A. 60-1103. The lien rights are the same, but the deadline is shorter and you must also name the general contractor in your lien statement.²

Filing Deadlines

The clock runs from the last day you furnished labor or materials at the site.

General contractors with a direct contract: four months from the last date of labor or materials.³
Subcontractors and suppliers: three months from the last date of labor or materials.²
Non-residential extension: on a commercial or other non-residential project, a contractor can extend the deadline to five months by filing a notice of extension within the initial four-month window and mailing it to the owner by certified and regular mail.³

Miss the deadline by a day and the lien is gone. Kansas courts enforce these dates strictly.

What the Lien Statement Must Contain

The lien is filed with the clerk of the district court in the county where the property sits. The verified statement must include:

The property owner’s name.
The claimant’s name and address, sufficient for service of process.
A description of the real property. This means a full legal description, not just a street address; you can pull it from the county Register of Deeds.
An itemized statement and the amount owed, or a copy of the written agreement or promissory note if one exists.

A subcontractor or supplier filing under 60-1103 must also name the general contractor.²

The docket fee is $14 plus a $22 surcharge, for a total of $36 based on current court fee schedules.⁴

Extra Rules for Residential Property

Kansas treats residential jobs differently. A residential property is a structure built for use as a residence by no more than two families.³ Two extra requirements apply.

Warning Statement

A subcontractor or supplier seeking a lien on residential property must have sent a warning statement to at least one owner before filing. The statement identifies you as a supplier or subcontractor, names the general contractor, gives the job number and address, and warns the owner that Kansas law allows you to file a lien if the contractor doesn’t pay you. In place of sending it yourself, you can hold a copy signed by the owner acknowledging receipt from the contractor or from you.⁵

The warning statement is not required if your total claim is $250 or less.⁵

Notice of Intent on New Construction

For new residential construction, meaning new builds rather than renovations or additions, a separate step protects your lien if the home sells. To keep your lien enforceable against a good-faith purchaser, file a notice of intent to perform with the district court clerk before the deed transferring ownership is recorded.⁶ Skip this and the sale to an uninformed buyer wipes out your lien rights.

Priority: When Your Claim Sits in Line

Priority in Kansas does not run from when you filed the lien statement. It relates back to when you first started furnishing labor or materials at the site. Your lien beats any lien or encumbrance recorded after that date.¹

This matters most against mortgages. A construction mortgage recorded before any work began has priority over all mechanics liens on that project. But if a mortgage was recorded after work had already started, the mechanics lien comes first.

When several contractors work under separate contracts on the same improvement, all their liens share one priority date: the date the earliest unpaid claimant began work. If that earliest lien is paid off or discharged, the shared date shifts forward to the next earliest unpaid lien.¹ So claimants on the same project aren’t racing each other to the courthouse.

Enforcing the Lien

The filed lien does not itself pay you. It clouds title, making the property hard to sell or refinance until the debt is resolved. That leverage carries an expiration date.

You must file a foreclosure lawsuit within one year of filing your lien statement.⁷ If a promissory note was attached to the lien statement instead of an itemized claim, the one-year period runs from the note’s maturity date. Let this pass and the lien dies. A breach of contract claim may survive, but the security interest in the property is lost.

Once you file suit, K.S.A. 60-2201 makes the action itself notice to third parties that the property is in dispute, so no one can acquire an interest that trumps your claim while the suit is pending. That protection only holds if you serve the summons or make first publication within 90 days of filing the petition.⁸

To win the foreclosure, you must prove you furnished the labor or materials, complied with the notice and filing requirements, and are owed the amount claimed. If the court agrees, it can order the property sold at public auction, with proceeds distributed by lien priority and any surplus returned to the owner.

Lien Waivers in the Contract

K.S.A. 16-1803 makes any contract clause that tries to waive, release, or extinguish mechanics lien rights in advance unenforceable as a matter of public policy.⁹

The statute does allow one exception: a contract can require you to provide a waiver of lien rights as a condition for payment, but only up to the amount you have actually been paid.⁹ Owners and general contractors commonly require waivers as part of the draw process on that basis.

Watch the difference between conditional and unconditional waivers. A conditional waiver takes effect only after the payment clears your account. An unconditional waiver is effective the moment you sign, whether the check clears or not. Don’t sign an unconditional waiver until the funds are confirmed; if the payment bounces afterward, the lien rights for that amount are gone.

Public Projects Use Bond Claims, Not Liens

You cannot file a mechanics lien against government-owned property. Roads, schools, and public buildings are immune. Kansas instead requires a payment bond on public works projects under K.S.A. 60-1111, and that bond is what protects subcontractors and suppliers on public jobs.¹⁰

If a public project leaves you unpaid, your claim runs against the general contractor’s bond, not the property. Bring the bond claim within six months of the completion of the public improvement.¹⁰ That window is tighter than the one-year foreclosure deadline on private liens, so calendar it the day the project wraps.

How an Owner Can Clear a Lien

Owners aren’t forced to sit through litigation to clean up title. K.S.A. 60-1110 lets the owner (or general contractor) post a bond that substitutes for the lien. It must run to the state of Kansas for the benefit of all potential lien claimants, be secured by sufficient sureties, and be approved by a district court judge.¹¹

The bond must be at least the full contract price if it covers all potential lien claims on the project, or at least the disputed amount if it covers a single claim. Once approved, existing liens are discharged and no new ones can attach for work covered by the bond. The claimant can still sue; the suit just runs against the bond rather than the property. Owners often use this to free up a sale or refinance.

Don’t File a Lien You Can’t Support

An inflated or baseless lien carries both civil and criminal exposure in Kansas. Under K.S.A. 58-4302, once a court finds a lien fraudulent, the owner can bring a damages action for actual damages up to $10,000 per violation (or the full amount if damages exceed $10,000), plus attorney fees and costs, and the court can permanently bar the filer from recording future liens without court approval.¹² Knowingly filing a false lien is also a severity level 8 nonperson felony under K.S.A. 21-5940.¹³

If the Owner Files Bankruptcy

An owner’s bankruptcy filing stops collection immediately. The automatic stay under 11 U.S.C. § 362 blocks any act to enforce a lien against property of the estate, including a pending foreclosure suit.¹⁴

A mechanics lien that was properly filed before the bankruptcy petition is treated as a secured claim to the extent of the property’s value under 11 U.S.C. § 506.¹⁵ Secured creditors are paid ahead of unsecured creditors, which is a real advantage. If the property is worth more than the total secured claims against it, you should recover in full; if not, the unsecured portion of your claim goes into the general pool. File a proof of claim and participate in the case. Holding a lien alone doesn’t get you paid.
