California Code of Civil Procedure section 2025.230 governs depositions of organizations rather than individuals. It does two things at once: it requires the party noticing the deposition to describe the subjects for examination with reasonable particularity, and it requires the organization to designate and produce the people most qualified to testify on those subjects based on information known or reasonably available to it.1California Legislative Information. California Code of Civil Procedure 2025.230
When the Statute Applies
Section 2025.230 comes into play only when the named deponent is “not a natural person.” That covers businesses, corporations, government agencies, partnerships, and similar entities.1California Legislative Information. California Code of Civil Procedure 2025.230 If you are deposing a specific individual by name, this section does not apply, and the ordinary deposition rules govern.
The two duties in the statute are linked by design. Clear topics from the noticing side let the organization pick the right witness. The right witness, properly prepared, produces testimony that binds the organization on those topics.
Describing Topics With Reasonable Particularity
The statute does not define “reasonable particularity,” and California courts have not fixed a bright-line test. In practice, the standard sits between two extremes. A topic like “all facts related to the plaintiff’s claims” is too vague; the organization cannot tell who inside the company should prepare or which records to pull. Fragmenting a subject into dozens of hyper-specific micro-topics runs into problems from the other direction.
A workable topic is specific enough that the organization can identify who handles that area and what documents that person should review. “The company’s hiring and termination procedures for warehouse employees from 2022 to 2025” tells the organization to send its HR director with the relevant personnel files. “Employment matters” leaves the organization guessing.
If you receive a notice with topics you consider too vague, meet and confer before running to the judge. California requires a good-faith attempt to resolve discovery disputes informally, in person, by phone, or by video, before filing any motion.2California Legislative Information. California Code CCP 2016.040 A short phone call often narrows the topics to something both sides can accept.
Designating the Person Most Qualified
Once the organization receives a properly noticed deposition, it must designate and produce the people most qualified to testify on the listed topics.1California Legislative Information. California Code of Civil Procedure 2025.230 In California practice this witness is usually called the Person Most Qualified, or PMQ, though the statute itself does not use that label. The organization can send different witnesses for different topics, and often should when the topics span unrelated departments.
The organization has real discretion in who it picks. It does not have to send the CEO, and it does not have to send the person with the most direct firsthand involvement. It has to send someone who can speak to the organization’s collective knowledge on the noticed topics after adequate preparation. That is the defining difference from a regular deposition: the PMQ testifies on behalf of the organization, not just from personal experience.
Preparing the Witness
This is where entity depositions most often fall apart. Showing up and answering from memory is not enough. The organization has an affirmative duty to prepare the designated witness to testify about everything the organization knows or can reasonably access on the noticed topics. That means reviewing relevant documents, interviewing other employees with relevant knowledge, and studying records the witness would not encounter in day-to-day work.
The preparation duty does not shrink because the documents are voluminous or the topic is complex. If thousands of pages of records bear on a topic, the witness still needs to review them or be briefed thoroughly enough to testify meaningfully. A witness who answers “I don’t know” to every question is functionally the same as producing no one, and courts treat it that way.
The witness also needs to state the organization’s position on disputed issues, not just recite facts. If the topic is “the company’s reasons for terminating the plaintiff,” the PMQ has to be ready to give those reasons as the company’s official account, even without personal involvement in the decision.
Notice Timing
Section 2025.230 does not set the timing rules; other sections do. Under CCP 2025.270, the standard minimum notice for an oral deposition is 10 days after service. In unlawful detainer cases the minimum drops to 5 days. When the notice includes a subpoena for a consumer’s personal records or employment records, the minimum is 20 days.3California Legislative Information. California Code of Civil Procedure 2025.270
Entity depositions usually take more preparation than individual ones, so 10 days can be tight. Either side can ask the court to extend the timeline for good cause, and attorneys frequently agree to longer schedules informally to avoid unnecessary motion practice.
What Happens When Someone Falls Short
Non-compliance can come from either direction. The noticing party may describe topics too vaguely for anyone to prepare. The organization may fail to designate a witness, produce an unprepared one, or refuse to answer questions inside the noticed topics.
Motions to Compel
When a deponent fails to answer questions or produce documents specified in the notice, the party seeking discovery can move to compel. The motion has to be filed within 60 days after the deposition record is completed and must include a declaration showing an informal attempt to resolve the dispute.4California Legislative Information. California Code of Civil Procedure 2025.480 Missing that 60-day window means losing the right to compel, which catches attorneys off guard more often than it should.
Sanctions
California’s discovery sanctions statute, CCP 2023.030, gives courts a graduated toolkit.5California Legislative Information. California Code CCP 2023.030 Monetary sanctions shift the other side’s reasonable expenses, including attorney’s fees, to the non-compliant party or its counsel; the court must impose them unless the non-compliant party was substantially justified or sanctions would be unjust. Issue sanctions let the court treat disputed facts as established against the offender or bar it from supporting or opposing specific claims. Evidence sanctions block introduction of designated evidence. Terminating sanctions, reserved for the worst cases, can strike pleadings, dismiss the action, or enter default. The court can also treat the abuse as contempt.
Misuse of the discovery process includes failing to respond to an authorized discovery method, making evasive responses, and disobeying a court order to provide discovery.6California Legislative Information. California Code CCP 2023.010 Producing a wholly unprepared PMQ can fall within evasive responses, because showing up without answers defeats the purpose of the deposition. Courts typically escalate rather than starting at the top; a first failure usually draws a monetary award and an order to produce a properly prepared witness, with heavier consequences reserved for repeated defiance.
Comparison to Federal Rule 30(b)(6)
The mechanics will feel familiar to anyone who works in federal court. Federal Rule 30(b)(6) uses nearly identical language, requiring the noticing party to describe examination topics with reasonable particularity and requiring the organization to designate witnesses who can testify to what the organization knows.7Legal Information Institute. Rule 30 – Depositions by Oral Examination
One difference matters. The federal rule now explicitly requires the serving party and the organization to confer in good faith about the topics before or promptly after the notice is served.7Legal Information Institute. Rule 30 – Depositions by Oral Examination California does not build an identical pre-deposition conferral into 2025.230 itself, though the general meet-and-confer requirement before any discovery motion accomplishes something similar once a dispute arises.2California Legislative Information. California Code CCP 2016.040 If your case straddles both forums, watch which court’s rules govern each deposition.
Practical Strategy on Both Sides
If you are noticing the deposition, resist the urge to draft topics as broadly as possible. Overly broad topics invite objections and protective orders, and even when the deposition goes forward, a witness facing a sprawling vague list gives less useful testimony than one focused on specific subjects. Targeted topics also make it far easier to show the witness was inadequately prepared if the answers fall short.
If you are the organization, do not read the topics as narrowly as possible to limit exposure. That approach backfires when the court orders a second deposition with a properly prepared witness and awards the other side its fees. Prepare thoroughly on every noticed topic, and object formally to any topic that genuinely exceeds reasonable discovery rather than sandbagging at the deposition itself. An informal call to refine topics before the deposition almost always beats a motion to compel afterward, and costs a fraction of the fees.
