N.D. Cent. Code § 30.1-12-07
Unless supervised administration as described in chapter 30.1-16 is involved, each proceeding before the court is independent of any other proceeding involving the same estate. Petitions for formal orders of the court may combine various requests for relief in a single proceeding if the orders sought may be finally granted without delay. Except as required for proceedings which are particularly described by other sections of chapters 30.1-12 through 30.1-23, no petition is defective because it fails to embrace all matters which might then be the subject of a final order, proceedings for probate of wills or adjudications of no will may be combined with proceedings for appointment of personal representatives, and a proceeding for appointment of personal representative is concluded by an order making or declining the appointment.
