The clerk must not refuse to accept for filing any paper presented for that purpose solely because it is not presented in proper form as required by these rules or by any local rule or practice. Unless a rule requires service by the clerk, a party must, at or before the time of filing a paper, serve a copy on the other parties to the appeal or review. Service on a party represented by counsel must be made on the party's counsel. Service may be personal, by mail, or by third-party commercial carrier for delivery within 3 calendar days. When reasonable considering such factors as the immediacy of the relief sought, distance, and cost, service on a party must be by a manner at least as expeditious as the manner used to file the paper with the court.
Personal service includes delivery of the copy to a responsible person at the office of counsel.
Service by mail or by commercial carrier is complete on mailing or delivery to the carrier. Proof of service may appear on or be affixed to the papers filed. When these rules require the filing or furnishing of a number of copies, a court may require a different number by local rule or by order in a particular case. 95 Seventh Street, San Francisco, California. The duties of the clerk are set forth in FRAP 45 .
