N.D. Cent. Code § 30.1-29-11
Except as provided herein, the court shall require a conservator to furnish a bond conditioned upon faithful discharge of all duties of the trust according to law, with sureties as it shall specify. Unless reduced or waived by the court for good cause, the bond shall be in the amount of the aggregate capital value of the property of the estate in the conservator's control plus one year's estimated income, including veterans' administration benefits received during that year, minus the value of securities deposited under arrangements requiring an order of the court for their removal and the value of any land which the fiduciary, by express limitation of power, lacks power to sell or convey without court authorization. In lieu of sureties on a bond, the court may accept other security for the performance of the bond, including a pledge of securities or a mortgage of land.
