Kansas Mechanics Lien Deadlines

Commercial jobs need no notices, but a sub or supplier working on a home where the owner lives must mail the owner a warning statement, or there's no lien.

Plain-language rules for general contractors, subcontractors and suppliers on private jobs, from K.S.A. 60-1101 and following, plus a helper that works out your dates.

Answer a few questions about the job and get your dates, with calendar reminders. Nothing you enter leaves your browser.

Your best guess is fine; update it when you finish.

This is general information, not legal advice. Lien deadlines are strict and can change with details of your job that this tool doesn't ask about. Our recommended dates are set earlier than the legal deadline on purpose. If money is on the line, talk to a construction attorney in your state before your deadline.

If you're a subcontractor or supplier

  1. Home the owner lives in (or a new home being built for them to live in), 1 or 2 families: mail any one owner the statutory warning statement (the “Notice to owner” wording in the statute). The law doesn't set a deadline, but the owner is only on the hook for payments made after they receive it, so send it before you start or as soon as you can. Not needed if your total claim is $250 or less. When you file, attach an affidavit that you sent it. (K.S.A. 60-1103a)
  2. New home being built to sell: file a notice of intent to perform with the district court clerk before the deed to a buyer is recorded. Without it, your lien can't reach the home once a good-faith buyer owns it. The notice expires after 18 months unless you file a lien. (K.S.A. 60-1103b)
  3. File your lien statement with the clerk of the district court within 3 months after your last day of work, then serve or mail (restricted mail) a copy to an owner, anyone holding a recorded equitable interest, and whoever owes you. On non-residential jobs, filing a notice of extension inside the 3 months gives you 5. (K.S.A. 60-1103)
  4. Sue to foreclose within 1 year after you file. (K.S.A. 60-1105)

If you're the general contractor

  1. No early notice is required of you, except the notice of intent to perform on new homes built to sell. (K.S.A. 60-1103b)
  2. File your lien statement with the clerk of the district court within 4 months after your last day of work. On non-residential jobs, a notice of extension filed inside the 4 months gives you 5. (K.S.A. 60-1102)
  3. Sue to foreclose within 1 year after you file. (K.S.A. 60-1105)

Watch out for

How we count: the helper uses the base deadline (3 or 4 months), not the 5-month extension. Kansas's lien law has no weekend rule, so recommended dates are 7 days early (30 for the lawsuit), moved earlier to a weekday.

The law

Kansas mechanics' lien rules are in K.S.A. 60-1101 to 60-1110. We read the official text from the Kansas Revisor of Statutes.
