A motion to compel a subpoena in California is the mechanism for asking the court to force a non-party to answer questions, appear for a deposition, or produce documents after they’ve ignored or resisted a properly served subpoena. To succeed, you have to meet and confer in good faith, file the right documents under the right statute, and file on time. For subpoenas tied to a deposition, “on time” means within 60 days of when the deposition record was complete, and missing that window waives the discovery for good.
Which Statute Governs Your Motion
The statute you file under depends on what the witness was supposed to do.
If a deponent failed to answer a question or produce something specified in the deposition notice or deposition subpoena, the motion goes under CCP § 2025.480.1California Legislative Information. California Code CCP 2025.480 If a witness failed to comply with a subpoena requiring attendance or document production before a court, the motion goes under CCP § 1987.1, which lets the court quash, modify, or direct compliance on whatever terms it sees fit.2California Legislative Information. California Code CCP 1987.1
One important trap: a business records subpoena served on a non-party is treated as a type of deposition under California law. That means § 2025.480 and its 60-day clock apply to it, even though no one actually sits for questioning. People miss this because nothing about the situation feels like a deposition, but the statute doesn’t recognize the distinction.
The 60-Day Filing Deadline
For motions under CCP § 2025.480, you must file no later than 60 days after the completion of the record of the deposition.1California Legislative Information. California Code CCP 2025.480 The court has no discretion to extend that deadline. Miss it and the discovery is gone.
When the clock starts depends on what happened. For a standard oral deposition, the record is complete when the court reporter finalizes and delivers the transcript. For a business records subpoena where the non-party served written objections instead of producing documents, California courts have held that the record is complete on the date set for production, when the objections were received.
Motions under CCP § 1987.1 do not carry the same statutory 60-day deadline, but unreasonable delay can still damage your position. File promptly either way.
Meet and Confer Before You File
California requires a meet-and-confer declaration showing a “reasonable and good faith attempt” to resolve the dispute informally, and the attempt must happen in person, by telephone, or by videoconference.3California Legislative Information. California Code CCP 2016.040 A single email does not satisfy this.
Your declaration needs to lay out what you actually did: the dates you contacted the witness or their attorney, the method of communication, the substance of what was discussed, and why the dispute could not be resolved. Skipping this step, or handling it perfunctorily, will get the motion denied and can trigger sanctions against you for misusing the discovery process.4California Legislative Information. California Code CCP 2023.030
The Documents You Need to File
A complete motion package includes several distinct pieces. Missing one gives the court a reason to deny the motion or continue the hearing.
Notice of Motion
The notice tells the non-compliant witness and all other parties when and where the court will hear the motion. For a deposition-related motion, you can give this notice orally on the record at the deposition itself, or serve it in writing afterward.1California Legislative Information. California Code CCP 2025.480 Written service after the fact is the usual path.
Memorandum of Points and Authorities
This is your legal argument. Identify the governing statute, establish that the subpoena was validly issued and properly served, describe the non-compliance, and explain why the discovery is relevant. If the witness raised objections, address each one and explain why it fails.
Supporting Declaration
The declaration is your factual evidence, signed under penalty of perjury. Cover three things: that the subpoena was properly served, what the witness failed to do, and what you did to try to resolve it informally. Attach copies of the subpoena, proof of service, any objections you received, and your meet-and-confer correspondence as exhibits.
Separate Statement
Self-represented litigants miss this one most often. California Rules of Court require a separate statement for any motion involving the content of a discovery request or its response, including motions to compel answers at a deposition or production of documents.5Judicial Branch of California. California Rules of Court Rule 3.1345 – Format of Discovery Motions The separate statement must list each disputed request in full, the complete response or objection you received, and your factual and legal reasons for compelling a further response. It has to be self-contained so the judge does not need to flip through other documents to understand the dispute. Some courts allow a concise outline instead, but only with prior permission.
Certified Deposition Transcript
If the motion involves testimony at a deposition, lodge a certified copy of the relevant portions of the stenographic transcript with the court no less than five days before the hearing.1California Legislative Information. California Code CCP 2025.480 For audio or video depositions, a certified transcript of the relevant portions is required.
Filing and Serving the Motion
File the motion with the superior court handling your case. Most California courts accept electronic filing, and some require it. The filing fee for a discovery motion is $60 as of 2026.6Judicial Branch of California. Statewide Civil Fee Schedule Effective 01-01-2026
Serve a copy on the non-compliant witness (or their attorney) and on every other party in the case. For deposition motions where notice was not given orally at the deposition, service must be in writing.1California Legislative Information. California Code CCP 2025.480 File your proof of service with the court.
Objections You Should Expect
The witness or their attorney will usually oppose the motion rather than comply outright. The common grounds are worth anticipating in your memorandum.
- Privilege. The witness claims attorney-client privilege, work product, or another recognized privilege. When this has merit, the court will typically review the disputed materials in chambers or require a privilege log.
- Undue burden or expense. The witness argues that compliance would be unreasonably costly. For electronically stored information, the burden falls on the objecting party to prove the data comes from a source that is not reasonably accessible.1California Legislative Information. California Code CCP 2025.480
- Relevance. The witness contends the requested information has no bearing on the claims or defenses. Your motion needs to make the connection clear enough for the judge to see why the discovery matters.
- Privacy. Under CCP § 1987.1, the court can issue protective orders against unreasonable violations of privacy. Consumer records and employment records have additional protections under CCP §§ 1985.3 and 1985.6.2California Legislative Information. California Code CCP 1987.1
Even valid objections rarely defeat the whole subpoena. Courts have broad authority to narrow the scope of documents, impose a protective order, or shift some production costs to the requesting party.
What the Court Can Order
If the court grants the motion, it will order the witness to comply by a specified date. That order might require appearing for a rescheduled deposition, answering specific questions previously refused, or producing outstanding documents. Under CCP § 1987.1, the court can also modify the subpoena’s terms or attach conditions such as protective orders.2California Legislative Information. California Code CCP 1987.1
A witness who ignores the order faces contempt. Disobedience of a subpoena or refusal to be sworn or answer as a witness can be punished as contempt of court.7California Legislative Information. California Code CCP 1991 – Disobedience to Subpoena For deposition subpoenas, contempt can be imposed without a prior court order directing compliance, so a witness can face consequences for simply not showing up.8California Legislative Information. California Code CCP 1991.1
Sanctions and Cost Recovery
Sanctions rules differ depending on which statute governs, and the difference matters.
For deposition-related motions under CCP § 2025.480, monetary sanctions are essentially mandatory. The court must order the losing side to pay the prevailing party’s reasonable expenses, including attorney fees, unless the losing side acted with “substantial justification” or the sanction would be unjust.4California Legislative Information. California Code CCP 2023.030 A witness who raised a colorable privilege objection but lost may escape sanctions; a witness who simply ignored the subpoena will almost certainly not.
For motions under CCP § 1987.1, the standard is discretionary. The court may award reasonable expenses and attorney fees, but only if the motion was made or opposed in bad faith, without substantial justification, or if the subpoena itself was oppressive.9California Legislative Information. California Code CCP 1987.2 The bar is higher because the statute uses “may” rather than “shall.”
Confirm the Subpoena Was Properly Served First
None of this works if the original subpoena was defective. Before spending time on the motion, confirm service was valid. A subpoena duces tecum issued before trial must be accompanied by a copy of an affidavit showing good cause for the production, specifying exactly what is sought, explaining why those materials are relevant to the issues in the case, and stating that the witness has them in their possession or control.10California Legislative Information. California Code CCP 1985 A motion built on a defective subpoena will fail.
An attorney of record can sign and issue subpoenas without a court seal.10California Legislative Information. California Code CCP 1985 A self-represented party needs a subpoena issued by the clerk or a judge. Personal service on the witness is the standard method. Keep the proof of service; you’ll attach it to the motion declaration later.
