Notwithstanding section 30.1-02-03, the proposed ward may demand change of venue to either the county of residence or the county where the proposed ward is present. The court shall grant the demand if it is filed and served upon the petitioner more than three days before the hearing. If the demand is filed within three days of the hearing, the court may grant the demand upon good cause shown.
