N.D. Cent. Code § 47-10-15
When a person purports by proper instrument to convey real property in fee simple and subsequently acquires any title or claim of title to the real property, the real property passes by operation of law to the person to whom the property was conveyed or that person's successor. A quitclaim deed that includes the word "grant" in the words of conveyance, regardless of the words used to describe the interest in the real property being conveyed by the grantor, passes after-acquired title. The use of a quitclaim deed, with or without the inclusion of after-acquired title in the deed, does not create any defect in the title of a person that conveys real property. This section applies to any conveyance regardless of when executed.
