    How many days do you have to file a mechanics lien in North Dakota?

    Record the lien with the county recorder where the property sits within ninety days after finishing your contribution. It must describe the property and state the amount due, the first and last dates of work or supply, and who you contracted with. A late filing is still good against the owner, but not against good-faith buyers or lenders who acquired rights before filing, and not for amounts the owner already paid the contractor. No lien may be filed more than three years after the first material was furnished.1 NDCC 35-27-13; 35-27-14

    When is the North Dakota notice of intent to claim a lien due?

    Anyone extending credit or contracting with the owner's contractor or subcontractor must give the owner written notice by certified mail that a lien will be claimed, at least ten days before recording the lien. Before suing to enforce, the lienholder must also give written notice of intent: personal service at least ten days before suit, or registered mail at least twenty days before.1 NDCC 35-27-02(4); 35-27-24

    How long is a mechanics lien good for in North Dakota?

    Who can file a mechanics lien in North Dakota?

    Does a North Dakota lien claim have to be notarized?

    The lien statute lists what the recorded lien must contain and does not require an oath or notary acknowledgment.1 NDCC 35-27-13

    What about public jobs in North Dakota?

    For a public improvement costing more than $250,000, the governing body must take a bond for at least the contract price, which also secures payment of labor and material claims, and anyone with a lawful claim can sue on it. A claim is barred if suit is not filed within one year after the project is completed and accepted.2 NDCC 48-01.2-10; 48-01.2-12
