Errata Sheets in Arizona are governed statutorily by Rule 30(e) of the Rules of Civil Procedure for the Superior Courts of Arizona. Ariz. Rev. Stat. Ann. § 16-30 (2017). In order to preserve the witness’s right to make changes to the deposition transcript, the deponent or one of the parties must request the right to do so before the completion of the deposition. Id. If requested, the witness will have 30 days after being notified by the deposition officer that the transcript is available to both review the transcript and provide the deposition officer the list of changes and reasons for changes to the form and/or substance of the transcript. Id. Witnesses can make changes that directly contradict the original answer given in the deposition, but both the original answer and the corrected answer remain part of the record and can be used to impeach the witness at trial.
