N.D. Cent. Code § 47-19.1-03
Marketable title is held by a person and taken by that person's successors in interest free and clear of all interest, claims, or any charges whatever, the existence of which depends upon any act, transaction, event, or omission that occurred twenty years or more before the present date, whether evidenced by a recorded instrument or otherwise, and all interests, claims, and charges affecting the interest in real estate are barred and not enforceable, unless a person makes an adverse claim before twenty years from the date of recording of the conveyance or other title transaction under which title is claimed, and records a verified notice setting forth the nature of the person's adverse claim. A disability or lack of knowledge of any kind on the part of anyone may not extend the time for filing the notice after the expiration of the twenty years.
