North Dakota Century Code Title 35. Liens § 35-27-18. Construction lien on railway contracts obtainable

Every person that furnishes any labor, skill, or material for constructing, altering, or repairing any line of railway, or any improvement or structure appertaining to any line of railway by virtue of any contract with the owner, or the owner's agent, contractor, or subcontractor authorized in writing to contract for the owner, has a lien upon the line of railway and the right of way of the railway, and upon all bridges, depots, offices, and other structures appertaining to the line of railway, and all franchises, privileges, and immunities granted to the legal or equitable owner of the line of railway for the construction and operation of the railway, to secure the payment for the labor, skill, and materials, upon recording a lien, within ninety days from the last day of the month in which the labor or material was furnished, but a failure to record within the ninety days does not defeat the lien except to the extent specified in section 35-27-14.
