A party (you) cannot be the person who serves the summons (actually , it's called the citation). You need to send the citation and a copy of the complaint to an officer or private process server authorized to serve such documents in the State of California. That officer, or private process server, will then send you either a Return or an Affidavit of Service for you to file with the court.
