There is no fixed number of days for a motion to quash a subpoena deadline in California. Code of Civil Procedure Section 1987.1 simply requires that the motion be “reasonably made.” In practice, that means filing early enough for the court to hold a hearing — which itself must be set at least 16 court days after you serve your papers under CCP Section 1005 — before the date the subpoena orders you to comply. The real deadline is set by the court’s calendar and the compliance date on the subpoena, working backward.
What “Reasonably Made” Actually Means
CCP Section 1987.1 gives judges broad authority to quash, modify, or place conditions on a subpoena that commands you to appear, testify, or produce documents. The statute’s only timing language is that the motion be “reasonably made.” No specific day count.
Whether you meet that standard depends on how much time is left before the compliance date, how complicated your objections are, and whether you acted promptly after being served. Judges have little patience for someone who sits on a subpoena for weeks and then races into court claiming an emergency. The safest practice is to treat the day you receive the subpoena as the day the clock starts. If you believe the subpoena is improper, start drafting the motion that week.
Counting Backward From the Compliance Date
The binding constraint is CCP Section 1005. Your motion papers must be served on the opposing party at least 16 court days before the hearing. Court days exclude weekends and judicial holidays, so 16 court days is roughly three and a half calendar weeks. And the hearing itself has to happen before the compliance date on the subpoena, or the motion is pointless.1California Legislative Information. California Code of Civil Procedure 1003-1008
How you serve the papers pushes the deadline back further:
- Service by mail within California adds five calendar days to the 16-court-day minimum.
- Service by fax, express mail, or overnight delivery adds two calendar days.
- Electronic service adds two court days.
Factor in the service method from the start. A mailed motion that would have been timely if hand-delivered can arrive too late.
A Worked Example
Say the subpoena orders you to produce documents on June 25. You want the hearing before that, so you request a hearing date of June 23. Counting backward 16 court days from June 23 puts your service deadline around May 29. If you serve by mail, you need to mail everything around May 24. That leaves roughly a month from receipt of the subpoena to complete drafting, filing, and service. Get the subpoena on May 1 and you have room to work. Get it on May 20 and you are probably out of time for a formal motion.
Consumer Records: A Faster Route
If the subpoena targets a consumer’s personal records held by a third party — medical files, financial statements, employment records — CCP Section 1985.3 creates a separate framework. The consumer whose records are at stake receives notice and has two options: file a motion to quash, or serve written objections on the subpoena issuer and the custodian of records before the production date.2California Legislative Information. California Code of Civil Procedure 1985.3
Written objections are usually the faster move. Once you serve them, the burden flips: the party that issued the subpoena has to file a motion to compel if they still want the records. You do not need to go to court at all unless they push. A formal motion to quash is still available in the consumer-records context, but if you choose that route, the general “reasonably made” standard and the 16-court-day notice rule still govern.
If You’ve Already Missed the Window
Ignoring the subpoena is the worst option. A subpoena is a court order. Failing to comply exposes you to a contempt finding under CCP Section 1209, which carries fines and possible jail time. A judge who has to issue a contempt order to get your attention is unlikely to be receptive if you later try to challenge the subpoena on the merits.
When you’ve run out of time for a formal motion, informal negotiation is often the practical answer. Contact the attorney who issued the subpoena and ask for a narrower scope or an extended compliance date. Attorneys frequently agree to limit requests or push back production dates when the other side raises legitimate concerns in good faith. Many subpoena disputes resolve this way without a motion ever being filed.
The other consideration is cost. CCP Section 1987.2 lets the court award reasonable expenses, including attorney fees, against a party that acted in bad faith or without substantial justification, or that issued an oppressive subpoena. That risk cuts against filing a last-minute motion with no real legal basis just to delay compliance. It also gives you leverage when the other side refuses to withdraw a subpoena that plainly seeks privileged material.
Federal Subpoenas Served in California
If the subpoena came from a federal court, the state deadlines do not apply. Federal Rule of Civil Procedure 45 governs, and its timing works differently.
For a document or inspection subpoena, you can serve written objections on the issuing party before the earlier of the compliance date or 14 days after service of the subpoena. That shifts the burden: the other side must move to compel if they want to pursue the records.3Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
For a formal motion to quash, FRCP 45 requires only that the motion be “timely.” No specific number of days. Federal courts apply a reasonableness analysis similar to what California state courts use, weighing how long you held the subpoena before acting and whether the court has time to rule before compliance.3Legal Information Institute.

One structural point that catches people off guard: in federal court, the motion to quash must be filed in the district where compliance is required, not necessarily the district handling the underlying case. If you were ordered to produce documents in the Northern District of California while the case is pending in New York, the motion goes to the California federal court.
The Practical Bottom Line
Start with the compliance date on the subpoena. Set a target hearing date a few days earlier. Count back 16 court days from that hearing, then add whatever your service method requires. That is the last day you can serve your motion papers. Anything later, and you are relying on the court to grant an ex parte application shortening time, which judges do not do casually and never for someone who created their own emergency.
