(b) Notwithstanding subdivision (a), in an unlawful detainer action or other proceeding under Chapter 4 (commencing with Section 1159) of Title 3 of Part 3, an oral deposition shall be scheduled for a date at least five days after service of the deposition notice, but not later than five days before trial.

2025.280.

(a) The service of a deposition notice under Section 2025.240 is effective to require any deponent who is a party to the action or an officer, director, managing agent, or employee of a party to attend and to testify, as well as to produce any document, electronically stored information, or tangible thing for inspection and copying.

2025.290.

(a) Except as provided in subdivision (b), or by any court order, including a case management order, a deposition examination of the witness by all counsel, other than the witness’ counsel of record, shall be limited to seven hours of total testimony. The court shall allow additional time, beyond any limits imposed by this section, if needed to fairly examine the deponent or if the deponent, another person, or any other circumstance impedes or delays the examination.

(b) This section shall not apply under any of the following circumstances:

(1) If the parties have stipulated that this section will not apply to a specific deposition or to the entire proceeding.

(c) It is the intent of the Legislature that any exclusions made by this section shall not be construed to create any presumption or any substantive change to existing law relating to the appropriate time limit for depositions falling within the exclusion. Nothing in this section shall be construed to affect the existing right of any party to move for a protective order or the court’s discretion to make any order that justice requires to limit a deposition in order to protect any party, deponent, or other natural person or organization from unwarranted annoyance, embarrassment, oppression, undue burden, or expense.

2025.310.

With respect to those portions of an audio or video record of deposition testimony that are not designated by any party or that are ruled to be objectionable, the court may order that the party offering the recording of the deposition at the trial or hearing suppress those portions, or that an edited version of the deposition recording be prepared for use at the trial or hearing. The original audio or video record of the deposition shall be preserved unaltered. If no stenographic record of the deposition testimony has previously been made, the party offering an audio or video recording of that testimony under Section 2025.620 shall accompany that offer with a stenographic transcript prepared from that recording.

2025.410.

(a) Any party served with a deposition notice that does not comply with Article 2 (commencing with Section 2025.210) waives any error or irregularity unless that party promptly serves a written objection specifying that error or irregularity at least three calendar days prior to the date for which the deposition is scheduled, on the party seeking to take the deposition and any other attorney or party on whom the deposition notice was served.

(b) If an objection is made three calendar days before the deposition date, the objecting party shall make personal service of that objection pursuant to Section 1011 on the party who gave notice of the deposition. Any deposition taken after the service of a written objection shall not be used against the objecting party under Section 2025.620 if the party did not attend the deposition and if the court determines that the objection was a valid one.

(c) In addition to serving this written objection, a party may also move for an order staying the taking of the deposition and quashing the deposition notice. This motion shall be accompanied by a meet and confer declaration under Section 2016.040. The taking of the deposition is stayed pending the determination of this motion.

(d) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion to quash a deposition notice, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust.

(b) The court, for good cause shown, may make any order that justice requires to protect any party, deponent, or other natural person or organization from unwarranted annoyance, embarrassment, or oppression, or undue burden and expense. This protective order may include, but is not limited to, one or more of the following directions:

(1) That the deposition not be taken at all.

(2) That the deposition be taken at a different time.

(3) That a video recording of the deposition testimony of a treating or consulting physician or of any expert witness, intended for possible use at trial under subdivision (d) of Section 2025.620, be postponed until the moving party has had an adequate opportunity to prepare, by discovery deposition of the deponent, or other means, for cross-examination.

(4) That the deposition be taken at a place other than that specified in the deposition notice, if it is within a distance permitted by Sections 2025.250 and 2025.260.

(5) That the deposition be taken only on certain specified terms and conditions.

(6) That the deponent’s testimony be taken by written, instead of oral, examination.

(16) That examination of the deponent be terminated. If an order terminates the examination, the deposition shall not thereafter be resumed, except on order of the court.

(c) The party, deponent, or any other affected natural person or organization that seeks a protective order regarding the production, inspection, copying, testing, or sampling of electronically stored information on the basis that the information is from a source that is not reasonably accessible because of undue burden or expense shall bear the burden of demonstrating that the information is from a source that is not reasonably accessible because of undue burden or expense.

(d) If the party or affected person from whom discovery of electronically stored information is sought establishes that the information is from a source that is not reasonably accessible because of undue burden or expense, the court may nonetheless order discovery if the demanding party shows good cause, subject to any limitations imposed under subdivision (f).

(e) If the court finds good cause for the production of electronically stored information from a source that is not reasonably accessible, the court may set conditions for the discovery of the electronically stored information, including allocation of the expense of discovery.

(f) The court shall limit the frequency or extent of discovery of electronically stored information, even from a source that is reasonably accessible, if the court determines that any of the following conditions exist:

(1) It is possible to obtain the information from some other source that is more convenient, less burdensome, or less expensive.

(2) The discovery sought is unreasonably cumulative or duplicative.

(3) The party seeking discovery has had ample opportunity by discovery in the action to obtain the information sought.

(4) The likely burden or expense of the proposed discovery outweighs the likely benefit, taking into account the amount in controversy, the resources of the parties, the importance of the issues in the litigation, and the importance of the requested discovery in resolving the issues.

(g) If the motion for a protective order is denied in whole or in part, the court may order that the deponent provide or permit the discovery against which protection was sought on those terms and conditions that are just.

(h) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion for a protective order, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust.

(i) (1) Notwithstanding subdivision (h), absent exceptional circumstances, the court shall not impose sanctions on any party, deponent, or other affected natural person or organization or any of their attorneys for failure to provide electronically stored information that has been lost, damaged, altered, or overwritten as the result of the routine, good faith operation of an electronic information system.

(2)  This subdivision shall not be construed to alter any obligation to preserve discoverable information.

(b) If a deponent on whom a deposition subpoena has been served fails to attend a deposition or refuses to be sworn as a witness, the court may impose on the deponent the sanctions described in Section 2020.240.

2025.450.

(b) A motion under subdivision (a) shall comply with both of the following:

(1) The motion shall set forth specific facts showing good cause justifying the production for inspection of any document, electronically stored information, or tangible thing described in the deposition notice.

(d) If the party or party-affiliated deponent from whom discovery of electronically stored information is sought establishes that the information is from a source that is not reasonably accessible because of the undue burden or expense, the court may nonetheless order discovery if the demanding party shows good cause, subject to any limitations imposed under subdivision (f).

(g) (1) If a motion under subdivision (a) is granted, the court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) in favor of the party who noticed the deposition and against the deponent or the party with whom the deponent is affiliated, unless the court finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust.

(2) On motion of any other party who, in person or by attorney, attended at the time and place specified in the deposition notice in the expectation that the deponent’s testimony would be taken, the court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) in favor of that party and against the deponent or the party with whom the deponent is affiliated, unless the court finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust.

(h) If that party or party-affiliated deponent then fails to obey an order compelling attendance, testimony, and production, the court may make those orders that are just, including the imposition of an issue sanction, an evidence sanction, or a terminating sanction under Chapter 7 (commencing with Section 2023.010) against that party deponent or against the party with whom the deponent is affiliated. In lieu of, or in addition to, this sanction, the court may impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against that deponent or against the party with whom that party deponent is affiliated, and in favor of any party who, in person or by attorney, attended in the expectation that the deponent’s testimony would be taken pursuant to that order.

(i) (1) Notwithstanding subdivisions (g) and (h), absent exceptional circumstances, the court shall not impose sanctions on a party or any attorney of a party for failure to provide electronically stored information that has been lost, damaged, altered, or overwritten as the result of the routine, good faith operation of an electronic information system.

(2) This subdivision shall not be construed to alter any obligation to preserve discoverable information.

2025.460.

(a) The protection of information from discovery on the ground that it is privileged or that it is a protected work product under Chapter 4 (commencing with Section 2018.010) is waived unless a specific objection to its disclosure is timely made during the deposition.

(b) Errors and irregularities of any kind occurring at the oral examination that might be cured if promptly presented are waived unless a specific objection to them is timely made during the deposition. These errors and irregularities include, but are not limited to, those relating to the manner of taking the deposition, to the oath or affirmation administered, to the conduct of a party, attorney, deponent, or deposition officer, or to the form of any question or answer. Unless the objecting party demands that the taking of the deposition be suspended to permit a motion for a protective order under Sections 2025.420 and 2025.470, the deposition shall proceed subject to the objection.

(c) Objections to the competency of the deponent, or to the relevancy, materiality, or admissibility at trial of the testimony or of the materials produced are unnecessary and are not waived by failure to make them before or during the deposition.

(d) If a deponent objects to the production of electronically stored information on the grounds that it is from a source that is not reasonably accessible because of undue burden or expense and that the deponent will not search the source in the absence of an agreement with the deposing party or court order, the deponent shall identify in its objection the types or categories of sources of electronically stored information that it asserts are not reasonably accessible. By objecting and identifying information of a type or category of source or sources that are not reasonably accessible, the deponent preserves any objections it may have relating to that electronically stored information.

(e) If a deponent fails to answer any question or to produce any document, electronically stored information, or tangible thing under the deponent’s control that is specified in the deposition notice or a deposition subpoena, the party seeking that answer or production may adjourn the deposition or complete the examination on other matters without waiving the right at a later time to move for an order compelling that answer or production under Section 2025.480.

(f) Notwithstanding subdivision (a), if a deponent notifies the party that took a deposition that electronically stored information produced pursuant to the deposition notice or subpoena is subject to a claim of privilege or of protection as attorney work product, as described in Section 2031.285, the provisions of Section 2031.285 shall apply.

2025.470.

The deposition officer may not suspend the taking of testimony without the stipulation of all parties present unless any party attending the deposition, including the deponent, demands that the deposition officer suspend taking the testimony to enable that party or deponent to move for a protective order under Section 2025.420 on the ground that the examination is being conducted in bad faith or in a manner that unreasonably annoys, embarrasses, or oppresses that deponent or party.

2025.480.

(a) If a deponent fails to answer any question or to produce any document, electronically stored information, or tangible thing under the deponent’s control that is specified in the deposition notice or a deposition subpoena, the party seeking discovery may move the court for an order compelling that answer or production.

(b) This motion shall be made no later than 60 days after the completion of the record of the deposition, and shall be accompanied by a meet and confer declaration under Section 2016.040.

(c) Notice of this motion shall be given to all parties and to the deponent either orally at the examination, or by subsequent service in writing. If the notice of the motion is given orally, the deposition officer shall direct the deponent to attend a session of the court at the time specified in the notice.

(d) In a motion under subdivision (a) relating to the production of electronically stored information, the deponent objecting to or opposing the production, inspection, copying, testing, or sampling of electronically stored information on the basis that the information is from a source that is not reasonably accessible because of the undue burden or expense shall bear the burden of demonstrating that the information is from a source that is not reasonably accessible because of undue burden or expense.

(e) If the deponent from whom discovery of electronically stored information is sought establishes that the information is from a source that is not reasonably accessible because of the undue burden or expense, the court may nonetheless order discovery if the deposing party shows good cause, subject to any limitations imposed under subdivision (g).

(f) If the court finds good cause for the production of electronically stored information from a source that is not reasonably accessible, the court may set conditions for the discovery of the electronically stored information, including allocation of the expense of discovery.

(g) The court shall limit the frequency or extent of discovery of electronically stored information, even from a source that is reasonably accessible, if the court determines that any of the following conditions exists:

(1) It is possible to obtain the information from some other source that is more convenient, less burdensome, or less expensive.

(2) The discovery sought is unreasonably cumulative or duplicative.

(3) The party seeking discovery has had ample opportunity by discovery in the action to obtain the information sought.

(4) The likely burden or expense of the proposed discovery outweighs the likely benefit, taking into account the amount in controversy, the resources of the parties, the importance of the issues in the litigation, and the importance of the requested discovery in resolving the issues.

(h) Not less than five days prior to the hearing on this motion, the moving party shall lodge with the court a certified copy of any parts of the stenographic transcript of the deposition that are relevant to the motion. If a deposition is recorded by audio or video technology, the moving party is required to lodge a certified copy of a transcript of any parts of the deposition that are relevant to the motion.

(i) If the court determines that the answer or production sought is subject to discovery, it shall order that the answer be given or the production be made on the resumption of the deposition.

(j) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion to compel an answer or production, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust.

(k) If a deponent fails to obey an order entered under this section, the failure may be considered a contempt of court. In addition, if the disobedient deponent is a party to the action or an officer, director, managing agent, or employee of a party, the court may make those orders that are just against the disobedient party, or against the party with whom the disobedient deponent is affiliated, including the imposition of an issue sanction, an evidence sanction, or a terminating sanction under Chapter 7 (commencing with Section 2023.010). In lieu of or in addition to this sanction, the court may impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against that party deponent or against any party with whom the deponent is affiliated.

(l) (1) Notwithstanding subdivisions (j) and (k), absent exceptional circumstances, the court shall not impose sanctions on a deponent or any attorney of a deponent for failure to provide electronically stored information that has been lost, damaged, altered, or overwritten as the result of the routine, good faith operation of an electronic information system.

(2) This subdivision shall not be construed to alter any obligation to preserve discoverable information.

2025.510.

(a) Unless the parties agree otherwise, the testimony at a deposition recorded by stenographic means shall be transcribed.

(b)  The party noticing the deposition shall bear the cost of the transcription, unless the court, on motion and for good cause shown, orders that the cost be borne or shared by another party.

(c) Notwithstanding subdivision (b) of Section 2025.320, any other party or the deponent, at the expense of that party or deponent, may obtain a copy of the transcript.

(d) If the deposition officer receives a request from a party for an original or a copy of the deposition transcript, or any portion thereof, and the full or partial transcript will be available to that party prior to the time the original or copy would be available to any other party, the deposition officer shall immediately notify all other parties attending the deposition of the request, and shall, upon request by any party other than the party making the original request, make that copy of the full or partial deposition transcript available to all parties at the same time.

(e) Stenographic notes of depositions shall be retained by the reporter for a period of not less than eight years from the date of the deposition, where no transcript is produced, and not less than one year from the date on which the transcript is produced. The notes may be either on paper or electronic media, as long as it allows for satisfactory production of a transcript at any time during the periods specified.

(f) At the request of any other party to the action, including a party who did not attend the taking of the deposition testimony, any party who records or causes the recording of that testimony by means of audio or video technology shall promptly do both of the following:

(1) Permit that other party to hear the audio recording or to view the video recording.

(2) Furnish a copy of the audio or video recording to that other party on receipt of payment of the reasonable cost of making that copy of the recording.

(g) If the testimony at the deposition is recorded both stenographically and by audio or video technology, the stenographic transcript shall be the official record of that testimony for the purpose of the trial and any subsequent hearing or appeal.

(h) (1) The requesting attorney or party appearing in propria persona shall timely pay the deposition officer or the entity providing the services of the deposition officer for the transcription or copy of the transcription described in subdivision (b) or (c), and any other deposition product or service that is requested either orally or in writing.

(2) This subdivision shall apply unless responsibility for the payment is otherwise provided by law or unless the deposition officer or entity is notified in writing at the time the services or products are requested that the party or another identified person will be responsible for payment.

(3) This subdivision does not prohibit or supersede an agreement between an attorney and a party allocating responsibility for the payment of deposition costs to the party.

(4) Nothing in the case of Serrano v. Stefan Merli Plastering Co., Inc. (2008) 162 Cal.App.4th 1014 shall be construed to alter the standards by which a court acquires personal jurisdiction over a nonparty to an action.

(5) The requesting attorney or party appearing in propria persona, upon the written request of a deposition officer who has obtained a final judgment for payment of services provided pursuant to this subdivision, shall provide to the deposition officer an address that can be used to effectuate service for the purpose of Section 708.110 in the manner specified in Section 415.10.

(i) For purposes of this section, “deposition product or service” means any product or service provided in connection with a deposition that qualifies as shorthand reporting, as described in Section 8017 of the Business and Professions Code, and any product or service derived from that shorthand reporting.

2025.520.

(a) If the deposition testimony is stenographically recorded, the deposition officer shall send written notice to the deponent and to all parties attending the deposition when the original transcript of the testimony for each session of the deposition is available for reading, correcting, and signing, unless the deponent and the attending parties agree on the record that the reading, correcting, and signing of the transcript of the testimony will be waived or that the reading, correcting, and signing of a transcript of the testimony will take place after the entire deposition has been concluded or at some other specific time.

(c) Alternatively, within this same period, the deponent may change the form or the substance of the answer to any question and may approve or refuse to approve the transcript by means of a letter to the deposition officer signed by the deponent which is mailed by certified or registered mail with return receipt requested. A copy of that letter shall be sent by first-class mail to all parties attending the deposition.

(d) For good cause shown, the court may shorten the 30-day period for making changes, approving, or refusing to approve the transcript.

(e) The deposition officer shall indicate on the original of the transcript, if the deponent has not already done so at the office of the deposition officer, any action taken by the deponent and indicate on the original of the transcript, the deponent’s approval of, or failure or refusal to approve, the transcript. The deposition officer shall also notify in writing the parties attending the deposition of any changes which the deponent timely made in person.

(f) If the deponent fails or refuses to approve the transcript within the allotted period, the deposition shall be given the same effect as though it had been approved, subject to any changes timely made by the deponent.

(g) Notwithstanding subdivision (f), on a seasonable motion to suppress the deposition, accompanied by a meet and confer declaration under Section 2016.040, the court may determine that the reasons given for the failure or refusal to approve the transcript require rejection of the deposition in whole or in part.

2025.560.

(a) An audio or video recording of deposition testimony made by, or at the direction of, any party, including a certified recording made by an operator qualified under subdivisions (b) to (f), inclusive, of Section 2025.340, shall not be filed with the court. Instead, the operator shall retain custody of that recording and shall store it under conditions that will protect it against loss, destruction, or tampering, and preserve as far as practicable the quality of the recording and the integrity of the testimony and images it contains.

(b) Notwithstanding subdivision (a), for good cause shown, the court may grant leave to take a subsequent deposition, and the parties, with the consent of any deponent who is not a party, may stipulate that a subsequent deposition be taken.

(c) This section does not preclude taking one subsequent deposition of a natural person who has previously been examined under either or both of the following circumstances:

(1) The person was examined as a result of that person’s designation to testify on behalf of an organization under Section 2025.230.

(a) Any party may use a deposition for the purpose of contradicting or impeaching the testimony of the deponent as a witness, or for any other purpose permitted by the Evidence Code.

(b) An adverse party may use for any purpose, a deposition of a party to the action, or of anyone who at the time of taking the deposition was an officer, director, managing agent, employee, agent, or designee under Section 2025.230 of a party.

(3) Exceptional circumstances exist that make it desirable to allow the use of any deposition in the interests of justice and with due regard to the importance of presenting the testimony of witnesses orally in open court.

(d) Any party may use a video recording of the deposition testimony of a treating or consulting physician or of any expert witness even though the deponent is available to testify if the deposition notice under Section 2025.220 reserved the right to use the deposition at trial, and if that party has complied with subdivision (m) of Section 2025.340.

(e) Subject to the requirements of this chapter, a party may offer in evidence all or any part of a deposition, and if the party introduces only part of the deposition, any other party may introduce any other parts that are relevant to the parts introduced.

(f) Substitution of parties does not affect the right to use depositions previously taken.

(g) When an action has been brought in any court of the United States or of any state, and another action involving the same subject matter is subsequently brought between the same parties or their representatives or successors in interest, all depositions lawfully taken and duly filed in the initial action may be used in the subsequent action as if originally taken in that subsequent action. A deposition previously taken may also be used as permitted by the Evidence Code.
