North Dakota Century Code Title 47. Property § 47-25-06. Assignment

If the interest of any person engaged in business under a trade name changes or ceases to exist, or any other person becomes interested therein, the assignment of ownership must be registered within ninety days after any change takes place. Any trade name and its registration is assignable with the goodwill of the business in which the trade name is used. Assignment must be made by the assignor on forms prescribed by the secretary of state setting forth the trade name, the names and addresses of each assignee, and the nature of the business. The assignment must be filed by the secretary of state who, upon recording of the assignment, shall issue in the name of the assignee a new certificate for the remainder of the term of the registration or of the last renewal.
