When a default judgment or judgment of dismissal on the merits has been ordered for failure to appear, the judge within 20 days after notice was mailed may vacate said judgment order ex parte and grant a new trial on a proper showing by the defaulting party of lack of notice, mistake, inadvertence or excusable neglect as the cause of that party's failure to appear. Absolute or conditional costs not to exceed $50 to the other party may be ordered as a prerequisite to that relief.
A default judgment may be vacated by the judge upon a proper showing by the defendant that: (1) the defendant did not receive a summons before the trial within sufficient time to permit a defense and did not receive notice of the order for default judgment within sufficient time to permit application for relief within 20 days after notice, or (2) upon other good cause shown. Application for relief pursuant to this Rule 520(b) shall be made within a reasonable time after the applicant learns of the existence of the judgment and shall be made by motion in accordance with the procedure governing motions in the district court, except that the motion is filed with the court administrator of conciliation court. The order vacating the judgment shall grant a new trial on the merits and may be conditioned upon payment of absolute or conditional costs not to exceed $50.
The court administrator shall promptly notify the parties by mail of a new trial date.
