Alaska · AS 34.35.050–34.35.120Alaska construction lien deadlines: 120 days, the notice of completion and the six-month lien

In Alaska, if the owner hasn't recorded a notice of completion, a claim of lien must be recorded no later than 120 days after the claimant completes its contract or stops furnishing labor, materials, services or equipment (AS 34.35.068(a)). If the owner records a notice of completion – after completion, with at least five days' advance notice to claimants who gave a notice of right to lien – a claimant that got the advance notice or never gave a notice of right to lien must record within 15 days after the notice of completion is recorded (34.35.068(b), 34.35.071). A lien doesn't bind the property for more than six months after the claim is recorded unless a suit to enforce it is started in that time or within six months after a recorded extension notice; and once a suit is started, the lien is void against a good-faith buyer for value without notice unless a notice of the pending action was recorded before the buyer's deed (34.35.080).

The deadlines

  1. 1. Claim of lien (34.35.068(a))

    Within 120 days after the claimant finished or stopped.

  2. 2. Notice of completion (34.35.071)

    Can cut some claimants to 15 days after it's recorded.

  3. 3. Duration (34.35.080(a))

    Six months unless suit is filed (or extended once).

  4. 4. Buyer (34.35.080(c))

    Without a recorded notice of pending action, a good-faith buyer takes free.

What the TC can do

  • If the seller had work done within the filing window, ask for lien waivers from the contractor and subcontractors.
  • Send any recorded lien to the title company before closing.
  • Keep the waivers in the deal file.
