Alaska Lien Law Deadlines for Suppliers and Subcontractors
Alaska suppliers and subcontractors must record a claim of lien within 120 days after they last furnish materials or complete their contract, and start enforcement within 6 months of recording. After an owner records a notice of completion, you may have only 15 days to record a claim or a notice of right to lien, so the optional notice of right to lien is worth giving early.
Public date calculations cover Florida and Kansas. Alaska dates require qualified review.
Risk context
Alaska is High Risk for Suppliers
Alaska's 120-day recording window runs from your own last delivery, but it is not guaranteed. When an owner records a notice of completion, most claimants must record a claim of lien or a notice of right to lien within 15 days to keep their rights. Because the notice of right to lien is optional, it is easy to skip, and skipping it leaves you exposed to that shorter cutoff.

| Deadline Type | Timing | Details |
|---|---|---|
| Lien Filing | 120 days after you last furnish materials or complete your contract | Record the claim of lien within 120 days. A claim recorded late is unenforceable (AS 34.35.068(a), (c)). |
| Notice of Completion Cutoff | 15 days after the owner records a notice of completion | Once the owner records a notice of completion, most claimants must record a claim of lien or a notice of right to lien within 15 days. Recording the notice of right to lien in time keeps the 120-day window for the claim (AS 34.35.068(b)). |
| Preliminary Notice | Optional notice of right to lien, before furnishing | Not required. Giving it puts the burden on the owner to prove it did not know of or consent to your work, entitles you to advance notice before the owner records a notice of completion, and a recorded notice has priority over later encumbrances (AS 34.35.064, 34.35.071, 34.35.060). |
| Enforcement | 6 months after recording Claim of Lien | Suit to enforce must be filed within 6 months. Recording an extension notice within those 6 months adds another 6 months (AS 34.35.080(a)). |
| Statutes | Alaska Stat. Sec. 34.35.050; §34.35.070; §34.35.068; §34.35.080; §34.35.064 | Also AS 34.35.060 and 34.35.071. |
Supplier pitfalls
Common Supplier Mistakes in Alaska
Ignoring a recorded notice of completion
The 120-day window is not the only clock. After an owner records a notice of completion, most claimants have 15 days to record a claim of lien or a notice of right to lien. Giving the notice of right to lien before you deliver entitles you to advance warning before the owner records.
Counting from the end of the project instead of your last delivery
Alaska's 120 days run from the day you last furnished materials or completed your own contract. Waiting for the whole project to finish can put you past the deadline.
Missing the 6-month enforcement deadline
A recorded claim of lien lapses 6 months after recording unless you commence an action or record an extension notice within that period.

Common questions
Frequently Asked Questions
What are the Alaska lien law deadlines?
Record your claim of lien within 120 days after you last furnish materials or complete your contract, or within 15 days after an owner records a notice of completion if that rule applies to you. Then commence an enforcement action within 6 months of recording, or record an extension notice to add 6 months.
What notices are required in Alaska?
None is required. Alaska's notice of right to lien is optional: you may give it to the owner before furnishing. It helps because the owner then has to prove it did not know of or consent to your work, and because it entitles you to advance notice before the owner records a notice of completion.
When must the lien be filed in Alaska?
Record the claim of lien within 120 days after you last furnish materials or complete your contract. If the owner records a notice of completion, you may have only 15 days from that recording to record a claim or a notice of right to lien (AS 34.35.068).
What is the enforcement period in Alaska?
6 months after recording Claim of Lien. If you cannot commence an action by then, record an extension notice within the 6 months to add another 6 months (AS 34.35.080). See how long a mechanics lien lasts for what happens when a lien lapses.
What statutes apply to Alaska liens?
Alaska Stat. Sec. 34.35.050; §34.35.070; §34.35.068; §34.35.080; §34.35.064. The notice of completion and priority rules are in AS 34.35.071 and 34.35.060.
Are these the 2024 Alaska lien law deadlines?
This guide covers current Alaska law, reviewed in September 2026 against the official Alaska Statutes, rather than a 2024 snapshot. The 120-day recording window and 6-month enforcement period come from AS 34.35.068 and 34.35.080. If your claim depends on the law as it stood in 2024, confirm the version in effect with an Alaska construction attorney.
