How to File a Mechanics Lien in Alaska
Step 1 — Confirm you have lien rights in Alaska
Alaska's recorded rules cover general contractors, subcontractors and suppliers (AS § 34.35.068). Each of those roles has its own filing window — see Step 3. Alaska rule detail: File claim of lien within 120 days of last furnishing of labor or materials. No preliminary notice required.
Step 2 — Send the Alaska preliminary notice
Alaska requires a preliminary notice Post at site, notice of right to lien (AS § 34.35.072). It is a precondition, not a formality. It must reach District Recorder and Prime Contractor and Surety and Prime Contractor. Delivery: Certified Mail, Return Receipt Requested. Alaska rule detail: File claim of lien within 120 days of last furnishing. Serve copy on owner within 15 days of recording.
Step 3 — Your Alaska filing deadline
Alaska sets the window by claimant role: • General contractors: within 120 days of your last day of work or materials. • Subcontractors and suppliers: within 120 days of your last day of work or materials. The clock runs from last date of furnishing — not your invoice date. Punch-list and warranty callbacks generally do not restart it. Alaska rule detail: File suit to enforce lien within 6 months of recording. Lien expires after 6 months without enforcement.
Step 4 — Prepare and record the lien in Alaska
Record in the county where the property sits, under AS § 36.25.020. The document must identify the property, the owner of record, the amount actually owed, and what you furnished. Overstating the amount can void the claim outright. Alaska rule detail: Written notice within 90 days of last furnishing on public works projects. No mechanic's lien on public property.
Step 5 — Serve the recorded Alaska lien
Alaska requires service on District Recorder and Prime Contractor and Surety and Prime Contractor. Use Certified Mail, Return Receipt Requested and keep the receipt. In many states an unserved lien is unenforceable even though it appears on title. Alaska rule detail: File suit on public works payment bond within 1 year of last furnishing.
Step 6 — Enforce before the Alaska deadline expires
You must sue to foreclose within 6 months (filing) (40 U.S.C. § 3133(b)(2)). Miss it and the lien expires and title clears, leaving only a contract claim. Alaska rule detail: Second-tier claimants only. No notice = no bond claim.
Retainage rules that affect your Alaska claim
Alaska treats retainage on its own schedule (AS § 36.90.200), so money still held back may have a different due date than your progress billings. Alaska rule detail: File no sooner than 90 days AND no later than 1 year.
Other Alaska requirements that void liens
• Public contracts: prime must pay sub within 7 days of receiving payment from public owner. Interest accrues on late payments. • Retainage released within 60 days of substantial completion. 10% maximum retainage on public contracts.
Frequently Asked Questions
How long do I have to file a mechanics lien in Alaska?
Alaska requires the lien to be recorded within 120 days, measured from last date of furnishing. The exact window depends on your role — general contractors: within 120 days of your last day of work or materials.
Do I need to send a preliminary notice before filing in Alaska?
Yes. Alaska requires a preliminary notice Post at site (notice of right to lien). Failing to send it on time generally forfeits your lien rights entirely, regardless of how much you are owed.
Where do I file a mechanics lien in Alaska?
File with the county recorder's office in the county where the property is located. Filing in the wrong county does not preserve your deadline, and re-filing in the correct county after the deadline will not save the claim.
What happens if I miss the Alaska filing deadline?
Your lien rights are extinguished. Alaska courts do not grant extensions for missed mechanics lien deadlines. You would be left with a breach-of-contract claim against whoever hired you, which carries no security interest in the property and is far harder to collect.
How long does a mechanics lien last in Alaska?
Once recorded, you must file suit to enforce within 6 months (filing). If you do not, the lien expires automatically and no longer clouds the property's title.
