The style and form of process, the manner of service of process and papers, the fees of officers, and judgment for costs and execution shall be according to the rules and practices of the district court.

(2) Before the district court is required to take jurisdiction of the contest, the contestor must file with the clerk of the court a bond, with sureties, to be approved by the district judge, running to the contestee and conditioned to pay all costs in case of failure to maintain his or her contest.
