Step-by-step guide for Colorado

  1. 1

    Confirm your lien rights

    Verify you hold a valid contract, are properly licensed (if Colorado requires it), and that the work was on private property. Public projects require a payment bond claim, not a lien.

  2. 2

    Preliminary notice (not required in this state)

    Colorado does not require a preliminary pre-lien notice for most claimants, though some project types may have additional requirements. Sending a courtesy notice is still good practice.

  3. 3

    Track your deadline from last day of work

    Your lien must be recorded within 120 days of your last furnishing of labor or materials. Mark the calendar the day you finish work — this clock does not stop.

  4. 4

    Prepare the lien document

    Your lien claim must include: claimant name and address, property owner name, property description (legal description or address), amount claimed, description of labor/materials, and dates of first and last furnishing.

  5. 5

    Notarization (not required in this state)

    Colorado does not require notarization.

  6. 6

    File with the County Clerk and Recorder

    Record your lien with the County Clerk and Recorder in the county where the property is located. Filing fee is typically $13–$30. Request a file-stamped copy for your records.

  7. 7

    Serve a copy on the property owner

    Most states require you to mail or personally serve a copy of the filed lien on the property owner within a short window of recording. Check Colorado rules for exact timing and method of service.

  8. 8

    Enforce by month 6

    If the debt remains unpaid, you must file a lawsuit to foreclose on the lien within 6 months of recording. If you miss this deadline, the lien expires and the cloud on title is removed without payment.
