N.D. Cent. Code § 29-22-10

The verdict of the jurors may be rendered orally or in writing, as the jurors may elect, unless the court, at the time the case is submitted to the jurors, requires that it be rendered in writing. When the court so requires, the clerk of the court, under the direction of the court, shall provide blank verdicts of suitable form for any verdict the jurors may return in the action and such blank verdicts must be taken by the jurors when they retire.
