Kansas is one of the few states where a sub or supplier gets less time than the GC. Contractors who dealt directly with the owner have 4 months after their last work to file. Subs and suppliers have 3. On commercial jobs both can stretch to 5 months, but only if a Notice of Extension is filed and mailed on time.
Quick answer: GCs file a verified lien statement with the district court clerk within 4 months after their last labor or materials. Subs and suppliers file within 3 months. On non-residential property, either can extend to 5 months with a timely filed and mailed Notice of Extension. Sue to foreclose within 1 year after filing.

Who can file a lien in Kansas
Anyone who furnishes labor, equipment, materials or supplies under a contract with the owner can lien under K.S.A. 60-1101. Subs and suppliers who work under a contractor or subcontractor can lien under 60-1103, and the cost of hauling materials to the site counts. Supplier-to-supplier deliveries generally aren't lienable.
Notices before the lien
Kansas has no general preliminary notice on private commercial jobs, and no notice of commencement system. On residential work, subs and suppliers with claims over $250 must give the owner a statutory Warning Statement (K.S.A. 60-1103a). The law doesn't set a deadline, but the owner isn't liable for payments made to the GC before receiving it, so send it when you start.
On new residential construction, a sub or supplier who wants to keep lien rights after the house sells must file a Notice of Intent to Perform with the district court clerk before the deed to the buyer is recorded.
Filing the lien
The lien statement is filed with the clerk of the district court in the county where the property sits. It must be verified (sworn) and include the owner's name, your name and address, the contractor's name (for subs and suppliers), a property description and a reasonably itemized statement of what you're owed.
Names matter. Kansas courts have thrown out liens that named the contractor slightly wrong, so pull the exact legal name before you file.
Residential jobs
Residential means a structure used by no more than two families. On these jobs the extension isn't available, so the deadlines are a firm 4 months for GCs and 3 months for subs and suppliers. Subs and suppliers also need the Warning Statement, and on spec homes the Notice of Intent to Perform before the sale closes.
After you file
Subs and suppliers must serve a copy of the lien statement on an owner, any holder of a recorded equitable interest, and any party obligated to pay. Service can be personal, by restricted mail, or by posting at the property if no address can be found.
A suit to foreclose must be filed within 1 year after the lien statement is filed. The court can allow amendments, but not to increase the amount.
Mistakes that cost Kansas contractors their lien
- Using the GC's 4-month deadline when you're a sub or supplier with only 3 months.
- Counting on the 5-month extension on a home (it's non-residential only) or forgetting to mail the Notice of Extension.
- Naming the contractor even slightly wrong in the lien statement.
- Skipping the residential Warning Statement or the Notice of Intent to Perform on a spec home.
