In California, the last day to object to a deposition notice is three calendar days before the scheduled deposition. Under Code of Civil Procedure section 2025.410, any party served with a defective notice waives errors or irregularities unless a written objection specifying those defects is served on the noticing party and every other attorney or party at least three calendar days before the deposition date.1California Legislative Information. California Code CCP 2025.410 Miss that window, and the deposition can proceed on the noticing party’s terms.
How to Count the Three Days and Serve the Objection
The deadline runs on calendar days, not court days, so weekends and holidays count. Work backward from the deposition date and your objection must be served by the end of the third calendar day before it.
If you are serving the objection exactly three calendar days before the deposition, you must use personal service under CCP 1011.1California Legislative Information. California Code CCP 2025.410 Mail will not work at that point because the general mail extension pushes the effective service date past the deposition. Treat the three-day deadline as a hard wall. An objection that arrives even a day late is likely waived.
The objection has to go to the party who noticed the deposition and to every other attorney or party who received the notice. Leaving someone off the service list creates its own problem.
What the Written Objection Must Say
CCP 2025.410 requires the objection to be in writing and to specify the errors or irregularities being challenged.1California Legislative Information. California Code CCP 2025.410 A vague, catch-all objection is unlikely to be treated as valid if the issue reaches a court later. Identify each defect and tie it to the specific requirement the notice violates.
What You Can Object To
Grounds for objection fall into two broad categories.
Procedural Defects in the Notice
These are the clearest objections because you can point directly to a statutory requirement the notice fails to meet. Common examples:
- Insufficient lead time. A deposition generally must be set at least 10 days after service of the notice. The minimum drops to 5 days in unlawful detainer actions, and rises to 20 days when the deponent is commanded to produce personal records of a consumer or employment records.2California Legislative Information. California Code CCP 2025.270
- Location outside the distance limits. A natural person’s deposition must be taken within 75 miles of their residence, or within the county where the action is pending if that county is within 150 miles of the deponent’s residence. For organizations that are parties, the measurement is from the organization’s principal California office. A notice that picks a more distant location is defective unless the noticing party has already obtained a court order under CCP 2025.260.3California Legislative Information. California Code CCP 2025.2504California Legislative Information. California Code CCP 2025.260
- Missing required contents under CCP 2025.220, including a reasonably particular description of any documents or electronically stored information to be produced, clear identification of the deponent, disclosure of audio or video recording intentions, the production format for ESI, and disclosure of any financial arrangement between the noticing party and the deposition officer.5California Legislative Information. California Code CCP 2025.220
Substantive Problems
Even a procedurally clean notice can be challenged on substance:
- Privilege. If the deposition will inevitably require disclosure of attorney-client communications, work product, or other protected information.
- Relevance. The noticed topics or document requests have no reasonable connection to the claims or defenses in the case.
- Undue burden or oppression. A massive document demand with an unrealistic timeframe, or scheduling that would cause genuine hardship.
- Trade secrets and privacy. Material that would expose confidential business information or personal privacy interests often calls for a motion for a protective order under CCP 2025.420 rather than a simple written objection, because the court may need to craft conditions for any disclosure.6California Legislative Information. California Code CCP 2025.420
A protective order motion runs on a different track than the three-day objection and must include a meet and confer declaration under CCP 2016.040 showing a good-faith attempt to resolve the dispute informally.7California Legislative Information. California Code CCP 2016.040 Filing the motion does not automatically stay the deposition. Unless the court issues a stay or rules on the motion before the deposition date, the deposition can go forward as noticed.
What Happens If You Object Properly and Skip the Deposition
There is a real protection built into CCP 2025.410 for a valid objection. If you properly serve the written objection, do not attend the deposition, and the deposing party goes forward anyway, the transcript cannot be used against you at trial if a court later determines your objection was valid.1California Legislative Information. California Code CCP 2025.410 The shield depends on both pieces: a proper objection and non-attendance. Showing up after objecting undercuts it.
This is a judgment call with real risk. If the court later disagrees that your objection was valid, you have no-showed a properly noticed deposition, and the consequences below apply.
What Happens If You Miss the Three-Day Deadline
The waiver language in CCP 2025.410 is blunt. Without a timely written objection specifying the defect, you waive the right to challenge that error, and the deposition proceeds on the noticing party’s terms.1California Legislative Information. California Code CCP 2025.410
If a party or party-affiliated deponent then fails to appear without a valid objection on file, the deposing party can move to compel attendance under CCP 2025.450. The motion must include a meet and confer declaration, and if the court grants it, monetary sanctions are essentially mandatory. The court will order the non-appearing deponent or affiliated party to pay the deposing party’s reasonable expenses, including attorney’s fees, unless the failure was substantially justified or an award would be unjust.8California Legislative Information. California Code CCP 2025.450
Other parties who showed up expecting testimony can seek sanctions for the wasted appearance. And if the deponent still refuses to comply after a court order compelling attendance, the court can escalate to issue sanctions treating disputed facts as established against you, evidence sanctions blocking certain evidence, or terminating sanctions that effectively end your case.8California Legislative Information. California Code CCP 2025.450
If You Are Past the Deadline
Once the three-day window has closed on a party notice, the written-objection tool under CCP 2025.410 is gone for the defects you did not raise. Substantive protections through a motion for a protective order under CCP 2025.420 remain available, including requests to limit topics, bar inquiry into privileged or private matters, restrict who may attend, or terminate an examination already underway.6California Legislative Information. California Code CCP 2025.420 A protective order is not a cure for a missed notice-objection deadline, but it can address substantive harms the deposition would cause.
Non-Party Subpoenas Use a Different Tool
The three-day objection deadline in CCP 2025.410 governs deposition notices served on parties. When a non-party is subpoenaed, the mechanism for challenge is a motion to quash or modify under CCP 1987.1, which can be brought by a party, the subpoenaed witness, a consumer whose personal records are being sought, an employee whose employment records are targeted, or a person whose identifying information is sought in a free speech dispute.9California Legislative Information. California Code CCP 1987.1 The court can quash the subpoena, modify it, or order compliance with conditions, including protective orders against unreasonable or oppressive demands and orders protecting privacy.
