The court may serve any document issued by the court that is not required to be personally served, in the same manner that parties electronically serve documents if a party has agreed to accept electronic service, or upon the order of the court. (CCP 1010.6(C)(3)) The Judicial Council adopts rules relating to the integrity of electronic service. (CCP 1010.6(f))
Service by facsimile transmission is permitted only where the parties agree in writing. The notice or other paper must be transmitted to a facsimile machine maintained by the person on whom it is served at the facsimile machine telephone number as last given on any document filed in the cause and served on the party making the service. Service is complete at the time of transmission and is extended by two court days. The document served by facsimile transmission must bear a notation of the date and place of transmission and the facsimile telephone number to which transmitted, or accompanied by an unsigned copy of the affidavit or certificate of transmission containing the facsimile telephone number to which the document was transmitted. (CCP 1013(e))
