N.D. Cent. Code § 32-08.1-05
Before the writ of attachment shall be executed, a bond on the part of the plaintiff in the sum of at least five hundred dollars executed by sufficient surety shall be delivered to the officer, to the effect that if the defendant recovers judgment the plaintiff shall pay all costs that may be awarded to the defendant and all damages which the defendant may sustain by reason of the attachment. The affidavit of the surety annexed to such bond shall state that the surety is a resident of this state and worth double the sum specified in the bond in property therein above the surety's debts and exclusive of property exempt from execution. No bond is necessary when this state or any political subdivision thereof is plaintiff.
