(a) As used in this article:

(1) “Business” includes every kind of business described in Section 1270.

(2) “Record” includes every kind of record maintained by a business.

(b) Except as provided in Section 1564, when a subpoena duces tecum is served upon the custodian of records or other qualified witness of a business in an action in which the business is neither a party nor the place where any cause of action is alleged to have arisen, and the subpoena requires the production of all or any part of the records of the business, it is sufficient compliance therewith if the custodian or other qualified witness delivers by mail or otherwise a true, legible, and durable copy of all of the records described in the subpoena to the clerk of the court or to another person described in subdivision (d) of Section 2026.010 of the Code of Civil Procedure, together with the affidavit described in Section 1561, within one of the following time periods:

(1) In any criminal action, five days after the receipt of the subpoena.

(2) In any civil action, within 15 days after the receipt of the subpoena.

(3) Within the time agreed upon by the party who served the subpoena and the custodian or other qualified witness.

(c) The copy of the records shall be separately enclosed in an inner envelope or wrapper, sealed, with the title and number of the action, name of witness, and date of subpoena clearly inscribed thereon; the sealed envelope or wrapper shall then be enclosed in an outer envelope or wrapper, sealed, and directed as follows:

(1) If the subpoena directs attendance in court, to the clerk of the court.

(2) If the subpoena directs attendance at a deposition, to the officer before whom the deposition is to be taken, at the place designated in the subpoena for the taking of the deposition or at the officer’s place of business.

(3) In other cases, to the officer, body, or tribunal conducting the hearing, at a like address.

(d) Unless the parties to the proceeding otherwise agree, or unless the sealed envelope or wrapper is returned to a witness who is to appear personally, the copy of the records shall remain sealed and shall be opened only at the time of trial, deposition, or other hearing, upon the direction of the judge, officer, body, or tribunal conducting the proceeding, in the presence of all parties who have appeared in person or by counsel at the trial, deposition, or hearing. Records that are original documents and that are not introduced in evidence or required as part of the record shall be returned to the person or entity from whom received. Records that are copies may be destroyed.

(e) As an alternative to the procedures described in subdivisions (b), (c), and (d), the subpoenaing party in a civil action may direct the witness to make the records available for inspection or copying by the party’s attorney, the attorney’s representative, or deposition officer as described in Section 2020.420 of the Code of Civil Procedure, at the witness’ business address under reasonable conditions during normal business hours. Normal business hours, as used in this subdivision, means those hours that the business of the witness is normally open for business to the public. When provided with at least five business days’ advance notice by the party’s attorney, attorney’s representative, or deposition officer, the witness shall designate a time period of not less than six continuous hours on a date certain for copying of records subject to the subpoena by the party’s attorney, attorney’s representative, or deposition officer. It shall be the responsibility of the attorney’s representative to deliver any copy of the records as directed in the subpoena. Disobedience to the deposition subpoena issued pursuant to this subdivision is punishable as provided in Section 2020.240 of the Code of Civil Procedure.

(f) If a search warrant for business records is served upon the custodian of records or other qualified witness of a business in compliance with Section 1524 of the Penal Code regarding a criminal investigation in which the business is neither a party nor the place where any crime is alleged to have occurred, and the search warrant provides that the warrant will be deemed executed if the business causes the delivery of records described in the warrant to the law enforcement agency ordered to execute the warrant, it is sufficient compliance therewith if the custodian or other qualified witness delivers by mail or otherwise a true, legible, and durable copy of all of the records described in the search warrant to the law enforcement agency ordered to execute the search warrant, together with the affidavit described in Section 1561, within five days after the receipt of the search warrant or within such other time as is set forth in the warrant. This subdivision does not abridge or limit the scope of search warrant procedures set forth in Chapter 3 (commencing with Section 1523) of Title 12 of Part 2 of the Penal Code or invalidate otherwise duly executed search warrants.
