Cal. R. 8.923
If, after the record is certified, the trial court amends or recalls the judgment or makes any other order in the case, including an order affecting the sentence or probation, the clerk must promptly certify and send a copy of the amended abstract of judgment or other order as an augmentation of the record to all those who received the record under rule 8.872(b). If there is any additional document or transcript related to the amended judgment or new order that any rule or order requires be included in the record, the clerk must send these documents or transcripts with the amended abstract of judgment or other order. The clerk must promptly copy and certify any such document and the reporter must promptly prepare and certify any such transcript.
If, after the record is certified, the trial court clerk or the reporter learns that the record omits a document or transcript that any rule or order requires to be included, the clerk must promptly copy and certify the document or the reporter must promptly prepare and certify the transcript. Without the need for a court order, the clerk must promptly send the document or transcript as an augmentation of the record to all those who received the record under rule 8.922(b).
At any time, on motion of a party or on its own motion, the appellate division may order the record augmented or corrected as provided in rule 8.841.
