CA Civ Proc Code Section 116.730

(a)

A defendant who did not appear at the hearing in the small claims court may file a motion to vacate the judgment with the clerk of the small claims court. The motion shall be filed within 30 days after the clerk has mailed notice of entry of the judgment to the parties.

(b)

The defendant shall appear at any hearing on the motion, or submit written justification for not appearing together with a declaration in support of the motion.

(c)

Upon a showing of good cause, the court may grant the motion to vacate the judgment. If the plaintiff is not present, the court shall hear the motion in the plaintiff’s absence.

(d)

If the motion is granted, and if all parties are present and agree, the court may hear the case without rescheduling it. If the plaintiff is not present, the judge or clerk shall reschedule the case and give notice in accordance with Section 116.330.

(e)

If the motion is denied, the defendant may appeal to the superior court only on the denial of the motion to vacate the judgment. The defendant shall file the notice of appeal with the clerk of the small claims court within 10 days after the small claims court has mailed or delivered notice of the court’s denial of the motion to vacate the judgment.

(f)

If the superior court determines that the defendant’s motion to vacate the judgment should have been granted, the superior court may hear the claims of all parties without rescheduling the matter, provided that all parties are present and the defendant has previously complied with this article, or may order the case transferred to the small claims court for a hearing.
