How to File a Mechanics Lien

An 8-step guide from preliminary notice to getting paid. Filing yourself is legal in every state — these steps apply nationally, with state-specific variations.

  1. 1

    Confirm you have lien rights

    • You must hold a valid contract (written or oral, depending on the state) to perform labor or furnish materials for an improvement to real property.
    • Most states require the claimant to hold a valid contractor's license. Filing a lien without the required license can invalidate your claim.
    • Lien rights apply only to private projects. For public projects (government-owned property), your remedy is a payment bond claim, not a mechanic's lien.
    • Employees who are owed wages cannot file a mechanic's lien — that is a wage claim through the state labor department.
  2. 2

    Send preliminary / pre-lien notice if required

    • Roughly a dozen states require anyone who is not in direct contract with the property owner (subcontractors, suppliers, equipment lessors) to send a formal preliminary notice early in the project.
    • Deadlines for preliminary notices are measured from your first day of furnishing — not from when payment problems begin. States include CA (20 days), FL (45 days), AZ (20 days), WA (60 days), OR (8 business days), NV (31 days), UT (20 days), TX (monthly), and others.
    • Missing the preliminary notice deadline can permanently bar your lien rights in states that require it — even if you file the lien itself on time.
    • Best practice: send the preliminary notice on the same day you mobilize on the project. Do not wait.
  3. 3

    Track your deadline from the last day of work

    • The lien filing deadline is measured from your last day of furnishing labor or materials to the project — not from the invoice date, not from when payment was due.
    • Deadlines range from 45 days (Hawaii) to 1 year (Mississippi, New York). Most states cluster around 90–120 days.
    • Keep a dated job log. The moment you know a job is finishing, mark the potential lien deadline on your calendar.
    • Use our deadline calculator to find your exact deadline once you know your last day of work.
  4. 4

    Prepare the lien document

    • Required contents vary by state but generally include: (1) claimant name and address, (2) property owner name, (3) general contractor name (if you are a sub), (4) property description (legal description is preferred; a street address may suffice), (5) unpaid amount claimed, (6) description of labor or materials furnished, and (7) first and last dates of furnishing.
    • The property's legal description (lot, block, subdivision) is more reliable than a street address and is required in some states. Find it on the property deed, the county assessor's website, or the building permit.
    • Do not include amounts for work you did not perform, equipment not used on this property, or unrelated projects.
    • Many states provide a statutory lien form — use it when available to avoid technical defects.
  5. 5

    Notarize the lien if required

    • Several states require the lien to be notarized before recording: Louisiana, Montana, South Carolina, Georgia, and Mississippi, among others.
    • Georgia and Mississippi additionally require witnesses (2 in Georgia, 2 in Mississippi).
    • Online notarization services (such as Notarize.com) let you complete this step in minutes from any device.
    • Even in states that do not require notarization, having the lien notarized can add credibility and reduce the chance of a dispute about execution.
  6. 6

    File with the correct county office

    • Record the lien with the appropriate county office in the county where the property is located. Common recording offices: County Recorder, County Clerk, Register of Deeds, Prothonotary (PA/DE), Circuit Court Clerk, or Bureau of Conveyances (HI).
    • Filing fees vary by state and county, typically ranging from $10 to $175.
    • File in person or by mail. Many counties now accept electronic filing. Always request a file-stamped copy.
    • The lien is effective from the date of recording. Your enforcement deadline runs from this date.
  7. 7

    Serve a copy on the property owner

    • Most states require you to mail or personally deliver a copy of the recorded lien to the property owner within a specific number of days of recording (commonly 2–30 days).
    • Service is typically by certified mail or personal delivery. Keep the return receipt.
    • Some states also require service on the general contractor if you are a subcontractor.
    • Failure to properly serve the owner can make the lien unenforceable in states with mandatory service requirements.
  8. 8

    Enforce (foreclose) before the deadline if unpaid

    • A recorded lien clouds the property title — the owner typically cannot sell or refinance until the lien is resolved. This creates significant leverage to negotiate payment.
    • If payment is not received, you must file a lawsuit to foreclose on the lien before the enforcement deadline. This deadline runs from the date the lien was recorded.
    • Enforcement deadlines range from 3 months (California) to 10 years (Oregon). Most states require suit within 1–2 years.
    • If you miss the enforcement deadline, the lien expires by operation of law and can be released from title without payment.
    • Once you receive payment, you must record a lien release (satisfaction of lien) to clear the property title.
