After a verdict has been rendered, it must be recorded on the minutes and read to the jury, and the jurors must be collectively asked whether such is their verdict. Even though no juror makes any declaration in the negative, the jury must, if either party makes such an application, be polled and each juror separately asked whether the verdict announced by the foreman is in all respects his verdict. If upon either the collective or the separate inquiry any juror answers in the negative, the court must refuse to accept the verdict and must direct the jury to resume its deliberation. If no disagreement is expressed, the jury must be discharged from the case, except as otherwise provided in section 400.27.
