N.D. Cent. Code § 10-33-132
Whenever a foreign corporation authorized to conduct activities in this state is a party to a statutory merger permitted by the laws of the jurisdiction under which it is incorporated, and the corporation is not the surviving organization, the surviving organization shall, within thirty days after the merger becomes effective, file with the secretary of state a certified statement of merger duly authenticated by the proper officer of the state or country where the statutory merger was effected. It is not necessary for any foreign organization, which is the surviving organization in a merger, to procure either a new or amended certificate of authority to conduct activities in this state unless the name of the organization is changed thereby or unless the organization desires to pursue in this state purposes other than those which it is authorized to transact in this state.
