N.D. Cent. Code § 30.1-08.1-03

If the court finds under chapter 32-23 that the will has been properly executed and that the plaintiff testator has the requisite testamentary capacity and freedom from undue influence, it shall declare the will valid and order it placed on file with the court. For the purposes of section 30.1-12-02, a finding of validity under this chapter shall constitute an adjudication of probate. The will shall be binding in North Dakota unless and until the plaintiff-testator executes a new will and institutes a new proceeding under this chapter naming the appropriate parties to the new proceeding as well as the parties to any former proceeding brought under this chapter.
