N.D. Cent. Code § 30.1-13-04
Any person desiring notice of any order or filing pertaining to a decedent's estate in which the person has a financial or property interest may file a demand for notice with the court, at any time after the death of the decedent, stating the name of the decedent, the nature of the person's interest in the estate, and the demandant's address or that of the demandant's attorney. The clerk shall mail a copy of the demand to the personal representative, if one has been appointed. After filing of a demand, no order or filing to which the demand relates shall be made or accepted without notice, as prescribed in section 30.1-03-01, to the demandant or the demandant's attorney. The validity of an order which is issued or filing which is accepted without compliance with this requirement shall not be affected by the error, but the petitioner receiving the order or the person making the filing may be liable for any damage caused by the absence of notice. The requirement of notice arising from a demand under this provision may be waived in writing by the demandant and shall cease upon the termination of the demandant's interest in the estate.
