Cal. Rules of Court, rule 8.914

(a) Application

If the court has a local rule for the appellate division electing to use this form of the record, the original trial court file may be used instead of a clerk's transcript. This rule and any supplemental provisions of the local rule then govern unless the trial court orders otherwise after notice to the parties.

(b) When original file must be prepared

Within 20 days after the filing of the notice of appeal, the trial court clerk must put the trial court file in chronological order, number the pages, and attach a chronological index and a list of all attorneys of record, the parties they represent, and any unrepresented parties.

(c) Copies

The clerk must send a copy of the index to the appellant for use in paginating his or her copy of the file to conform to the index. If there is more than one appellant, the clerk must prepare an extra copy of the index for each additional appellant who is represented by separate counsel or self-represented. If the defendant is the appellant, a copy must also be prepared for the prosecuting attorney unless the prosecuting attorney has notified the court under rule 8.911 that he or she does not want to receive the record. If the People are the appellant, a copy must also be prepared for the respondent.
