To object to a deposition notice in California, you must serve a written objection that identifies the specific defect at least three calendar days before the scheduled deposition date. Miss that window and you waive any challenge to the notice; the deposition proceeds on the terms the other side chose, and the testimony can be used against you.1California Legislative Information. California Code CCP 2025.410 The rest is detail: how to serve the objection, what grounds hold up, and when a written objection alone won’t stop the deposition from happening.
The Three-Day Written Objection
The objection must be in writing, must identify the specific error or problem with the notice, and must be served on the party who noticed the deposition and on every other attorney or party who received it.1California Legislative Information. California Code CCP 2025.410 Serve early if you can. The three days are calendar days, not court days.
Service method matters at the deadline. When the objection goes out right at the three-day mark, CCP § 2025.410(b) requires personal service under CCP § 1011, not mail or electronic service. Earlier service allows other methods, but hand-delivery is the safe path once you’re near the cutoff.
A properly served objection carries a real consequence for the other side. If you object in writing, skip the deposition, and the court later finds the objection valid, the deposition testimony cannot be used against you at trial or any other hearing.2California Legislative Information. California Code CCP 2025.620 That protection only exists if the written objection was timely and specific.
Grounds That Hold Up
Objections that succeed usually fall into four categories.
The Notice Doesn’t Comply With the Statute
Under CCP § 2025.220, a deposition notice must state the address, date, and start time; name each deponent (or describe them specifically enough to identify them); describe any documents or electronically stored information the deponent must bring with reasonable particularity; and disclose any video or audio recording in addition to stenographic recording. It must be in at least 12-point type.3California Legislative Information. California Code CCP 2025.220
A notice missing any of these elements is objectionable. So is a notice that fails the minimum notice period: at least 10 days after service in most cases, only five days in unlawful detainer actions, and at least 20 days from issuance for depositions involving consumer or employment records subpoenas.4California Legislative Information. California Code CCP 2025.270
Scope Is Overbroad or Irrelevant
California allows discovery into any nonprivileged matter relevant to the subject of the pending case or reasonably calculated to lead to admissible evidence.5California Legislative Information. California Code CCP 2017.010 A notice that reaches past that scope, or that lists document categories so broad the deponent would have to produce nearly everything on hand, is vulnerable.
Undue Burden
Relevant topics can still be off-limits when compliance costs vastly outweigh evidentiary value, or when the deposition looks aimed at harassment. Electronically stored information is the frequent flashpoint, because searching legacy systems can run up costs quickly. The remedy here is usually a protective order under CCP § 2025.420 rather than outright quashing.6California Legislative Information. California Code CCP 2025.420
Privilege and Work Product
If the notice reaches into attorney-client communications, work product, or other privileged material, raise it in the pre-deposition written objection. Privilege requires a second objection during the deposition itself when the specific question is asked; a pre-deposition flag alone doesn’t preserve it.7California Legislative Information. California Code CCP 2025.460
How Service of the Notice Affects the Deadline
The 10-day minimum runs from service of the notice, and California extends that period based on the method of service. Mail service within California adds five calendar days. Mail to a recipient outside California but within the United States adds 10 days; outside the country, 20 days. Express mail or overnight delivery adds two court days, and fax service adds two court days as well.8California Legislative Information. California Code CCP 1013
These extensions can turn an apparently timely notice into a defective one. If the noticing party mailed the notice and counted only 10 days, the deposition is set too early and the notice itself is objectionable.
When a Written Objection Isn’t Enough
A written objection preserves your position, but by itself it doesn’t stop the deposition. If you want the deposition halted, file a motion to stay the deposition and quash the notice. Filing triggers an automatic stay until the court rules.1California Legislative Information. California Code CCP 2025.410
The motion must include a meet and confer declaration describing the efforts you made to resolve the dispute informally. A generic recital that “the parties were unable to resolve the dispute” will not pass muster.
The losing party on a motion to quash faces mandatory monetary sanctions. The court must order the unsuccessful side, its attorney, or both to pay the other party’s reasonable expenses and attorney’s fees, unless the losing position was substantially justified or sanctions would be unjust. That cuts in both directions, so a marginal motion is expensive to file.
Protective Orders
A protective order under CCP § 2025.420 is broader and more flexible than quashing. Any party, the deponent, or any other affected person may move for one before, during, or after the deposition, on a showing of good cause.6California Legislative Information. California Code CCP 2025.420 The court can order that the deposition not be taken at all, reschedule it, limit the topics, restrict who attends, change the recording method, require written questions instead of oral examination, seal the transcript, or terminate an examination in progress. Good cause requires actual evidence of the burden or harm, not just an assertion of inconvenience. Like a motion to quash, the protective order motion requires a meet and confer declaration.
Meet and Confer Before You File
California requires a real attempt at informal resolution before any discovery motion. The declaration must describe facts showing a reasonable, good-faith effort to resolve each issue in person, by telephone, or by videoconference.9California Legislative Information. California Code CCP 2016.040 Letters and emails alone don’t satisfy the statute. Skipping meet and confer is itself misuse of the discovery process under CCP § 2023.010(i).10California Legislative Information. California Code CCP 2023.010
Many deposition disputes settle at this stage. The noticing party agrees to narrow the document list or move the date, and no motion gets filed. Courts know this, and they read meet and confer declarations closely.
Objecting During the Deposition
Objections to the notice and objections during the deposition operate under different rules. Even if you filed no pre-deposition objection, some grounds must be raised on the record at the deposition or they’re gone.
Privilege is the primary example. When a question calls for privileged material, object on the record at that moment; failure to do so waives privilege for that testimony.7California Legislative Information. California Code CCP 2025.460 The same immediate-objection rule applies to problems that could be corrected on the spot, like the form of a question, the oath, or the conduct of counsel.
Objections based on relevancy, materiality, or admissibility work differently. Those are not waived by silence at the deposition and can be raised when the transcript is offered later. Objecting to relevancy at every question during the deposition is unnecessary.
An objection at the deposition doesn’t stop the examination unless you demand a suspension to seek a protective order. The testimony is taken subject to the objection, and the court sorts it out afterward.
The Seven-Hour Limit
Most California depositions are capped at seven hours of total testimony, counted across all examining attorneys except the deponent’s own counsel.11California Legislative Information. California Code CCP 2025.290 If the deposing party tries to go past that without a stipulation or court order, you can object and instruct the deponent to stop answering. The court can extend the limit when fairness requires it or when the deponent caused delay.
The cap does not apply to expert witness depositions, complex cases designated under California Rules of Court, Rule 3.400, employment cases brought by employees or applicants against employers, depositions of organizational designees under CCP § 2025.230, or cases where the parties stipulated the limit does not apply. In those situations, a scope-based protective order remains available even though the seven-hour objection is not.
What Waiver Costs
The waiver rule in CCP § 2025.410 is strict. Without a timely written objection, defects in the notice cannot be raised later.1California Legislative Information. California Code CCP 2025.410 You lose the ability to argue the notice was defective when the transcript is offered at trial. You lose the CCP § 2025.620 protection against use of the testimony. And you may produce documents or answer questions on topics a timely objection would have eliminated.
Waiver at the notice stage doesn’t strip every protection. Privilege objections and form objections at the deposition itself remain available. But notice-level defects, including short-notice violations and missing required information, are gone once the three-day window closes.
Sanctions Cut Both Ways
Filing meritless objections to stall a deposition is itself sanctionable. CCP § 2023.010 identifies “making, without substantial justification, an unmeritorious objection to discovery” as misuse of the discovery process, alongside seeking discovery outside the permissible scope and using discovery to cause unwarranted harassment or burden.10California Legislative Information. California Code CCP 2023.010
Under CCP § 2023.030, monetary sanctions are the default remedy: the offending party or attorney pays the other side’s reasonable expenses, including attorney’s fees.12California Legislative Information. California Code CCP 2023.030 They are mandatory unless the sanctioned party acted with substantial justification or sanctions would be unjust. More severe options exist, including issue sanctions, evidence sanctions, terminating sanctions, and contempt, but courts reserve those for repeated or egregious misconduct and work through lesser penalties first.
The framework rewards accuracy on both sides. Object without a reasonable basis and you may pay the other party’s costs. Push a deposition through despite a valid objection and you may see the testimony excluded and pay sanctions yourself. That structural pressure is what makes early, honest meet and confer the practical center of most deposition disputes in California.
