90-Day Filing Deadline Under N.D. Cent. Code § 35-27-06
All claimants must file a lien statement with the County Recorder of the county where the improved property is located within 90 days after completion of the last item of work or last furnishing of materials or services under § 35-27-06. The 90-day deadline is absolute and applies uniformly to general contractors, subcontractors, material suppliers, and equipment lessors. Each claimant's deadline runs from that claimant's own last date of furnishing — not the project completion date, not the prime contractor's last day, and not the date the owner accepted the work. Missing Day 90 permanently eliminates all mechanics lien rights for that claimant on that project. North Dakota's 53 counties each have a County Recorder office located in the county seat; the correct filing county is determined by the physical location of the project property.
Mandatory 30-Day Post-Filing Owner Notice — § 35-27-09
Within 30 days after filing the lien statement with the County Recorder, every North Dakota claimant must serve a copy of the filed lien statement on the property owner under § 35-27-09. This post-filing owner notice is mandatory — it is not optional best practice. Failing to serve the owner within the 30-day window can impair the lien's enforceability in subsequent court proceedings. Service can be accomplished by personal delivery or certified mail with return receipt. The 30-day window runs from the actual recording date stamped by the County Recorder. Serve the owner the same day the filing is confirmed to minimize risk. Retain all proof of service documentation — certified mail tracking, return receipts, or affidavits of personal service.
53 Counties and the Correct Filing Office
North Dakota has 53 counties, each with a County Recorder (sometimes titled Register of Deeds or Recorder of Deeds) located in the respective county seat. The correct filing county is determined by the physical location of the project property, not the contractor's home county or principal place of business. Major construction activity counties include Cass (Fargo), Burleigh (Bismarck), Grand Forks (Grand Forks), Ward (Minot), Williams (Williston — Bakken oil patch), McKenzie (Watford City — oil patch), and Stark (Dickinson — oil patch). Filing in the wrong county creates no valid lien on the property. Filing fees and recording requirements vary by county — contact the relevant County Recorder in advance to confirm. The Mechanics Lien Management State System identifies the correct county recorder for any North Dakota project address and calculates all filing and enforcement deadlines.
3-Year Enforcement Window Under § 35-27-13
Under N.D. Cent. Code § 35-27-13, a claimant must commence an action to enforce the lien in the District Court of the county where the property is located within 3 years from the date the lien statement was filed with the County Recorder. North Dakota's 3-year enforcement window is among the most generous in the US — far longer than Alaska's 6-month window, Rhode Island's 1-year window, and New Hampshire's approximately 210-day window. While the long window provides time for payment negotiations, a lien that sits unresolved loses practical leverage as time passes. Calendar the 3-year enforcement deadline immediately upon recording, set a 2-year reminder to reassess payment status, and retain North Dakota construction counsel if the dispute approaches the 2-year mark without resolution.
