Under CCP 414.10, anyone who is over 18 years old may serve a summons and complaint–except for a party.  Here, plaintiff’s service of the summons and complaint on the defendant was insufficient to give the court jurisdiction over the defendant.  Hence, the ensuing default judgment agains the defendant was properly set aside under CCP 473(d) as void on its face.  Substantial compliance and actual notice to the defendant are not enough to cure the defect in service.  The decision also suggests that a defendant’s general appearance does not waive inadequate service.
