California Business Records Subpoena: Four Clocks, Not One
Not legal advice. Rules attested September 29, 2026; last full pass August 17, 2026. The deposition rules added or changed on September 28, 2026 are awaiting attorney sign-off and are not yet in the methodology table. The discovery cutoffs and the expert exchange, which move to the next court day closer to trial under CCP § 2016.060 since September 29, 2026, are awaiting sign-off too. Verify every date yourself.

Each verified rule carries its own date on the methodology page, all of them September 29, 2026: the date the maintaining attorney last attested it. The last full pass, signed off on August 17, 2026, checked the rules against their official sources (the code, the California Rules of Court, or for court holidays the Judicial Council calendar), with the exceptions listed on the about page. Rules still awaiting sign-off are listed on the methodology page as not yet verified. County local rules are paraphrased summaries. Individual department and judge standing orders are included only where the court publishes them and we have read the document, so assume your own department has requirements beyond what you see here. Verify every date against the operative code sections, your court's rules and your department's own order before relying on it. Using this site creates no attorney-client relationship.
A subpoena that commands only the production of business records runs four clocks, and satisfying one does not satisfy the others. Two apply to every records subpoena: production no earlier than 20 days after the subpoena issues, and no earlier than 15 days after it is served on the custodian (CCP 2020.410(c)). Two more apply when the records are a consumer's personal records or an employee's employment records. Counted back from the production date, the custodian's 15 days decide how early everything else has to happen.
Your dates
Four clocks, not one
A subpoena for business records only must set production no earlier than 20 days after it issues or 15 days after it is served on the custodian, whichever is later. CCP § 2020.410(c). For consumer or employee records, serve the record subject at least 10 days before production and at least 5 days before you serve the custodian, plus the mail time. CCP §§ 1985.3(b), 1985.6(b). Counted back from production, the custodian's 15 days decide how early the record subject must be served.
The four clocks
- Twenty days from issuance. Production must be set at least 20 days after the subpoena issues (CCP 2020.410(c)). For consumer or employee records CCP 2025.270(c) says the same. Not service. Issuance.
- Fifteen days after service on the custodian. The same sentence of CCP 2020.410(c) sets production no earlier than 15 days after the subpoena is served, "whichever date is later." Counted back from production, that is the last day to serve the custodian of records.
- Five days before the custodian. The consumer or employee must be served at least 5 days before you serve the custodian, plus the CCP 1013 extension if service is by mail (CCP 1985.3(b)(3), 1985.6(b)(3)). Serving the custodian too early is an independent defect.
- Ten days before production. The consumer or employee gets the subpoena, any supporting affidavit and the statutory notice not less than 10 days before production, plus the CCP 1013 extension if by mail (CCP 1985.3(b)(2), 1985.6(b)(2)). The notice must be in a typeface designed to call attention to it. Meet the second and third clocks and this one is met too.
A worked example
Production is set for Friday, November 20, 2026, and the consumer will be served by mail within California. The custodian must be served by Thursday, November 5, 15 days before production. The consumer must be served 5 days before that plus 5 for mail, so by Monday, October 26. Twenty days before production is Saturday, October 31, so the subpoena has to issue by then; the calculator moves a backward count that lands on a weekend to the preceding court day and shows Friday, October 30. The 10-day clock alone would have allowed serving the consumer as late as November 5, which leaves no lawful day to serve the custodian.
Where the mail extension comes from
CCP 1985.3(b) and 1985.6(b) both add "the additional time provided by Section 1013 if service is by mail" to the consumer and employee notice periods. They have to say so because they sit outside the Civil Discovery Act. Inside the Act, CCP 2016.050 applies section 1013 to every method of discovery, which is why a mailed deposition notice also gets the extra 5 days.
Working backward means the extension costs you time
This is the direction-of-extension point, and it reverses here. On a response deadline, mail service gives you more time. On a notice period counted backward from a fixed production date, the extension moves your deadline earlier. Mailing the consumer notice does not buy you five days; it costs you five.
FAQ
How many days notice for a deposition subpoena for business records?
Production must be set no earlier than 20 days after the subpoena issues or 15 days after it is served on the custodian, whichever is later (CCP 2020.410(c)). For consumer or employee records, also serve the consumer or employee with a copy of the subpoena, any supporting affidavit and the statutory notice not less than 10 days before production and at least 5 days before the custodian, plus the additional time under CCP 1013 if service is by mail (CCP 1985.3(b), 1985.6(b)).
How long before serving the custodian must you serve the consumer?
At least 5 days, plus the CCP 1013 extension if by mail (CCP 1985.3(b)(3)). The custodian in turn must be served at least 15 days before production (CCP 2020.410(c)), so a consumer served by mail within California has to be served at least 25 days before production. Serving the custodian too early is an independent defect, and failure to comply with section 1985.3 is a sufficient basis for the witness to refuse to produce (CCP 1985.3(k)).
Does the 20-day rule run from service or from issuance?
From issuance. A subpoena for business records only must set production no earlier than 20 days after it issues (CCP 2020.410(c)), and for consumer or employee records CCP 2025.270(c) says the same. A second clock runs from service: production must also be at least 15 days after the custodian is served. Whichever date is later controls.
What is the California subpoena objection deadline?
It depends on whether the consumer or employee is a party. A party moves to quash or modify under CCP 1987.1 before the production date, with notice to the witness and the deposition officer at least 5 days before production (CCP 1985.3(g), 1985.6(f)(1)). A written objection alone does not stop production for a party. A consumer or employee who is not a party may instead serve a written objection on the subpoenaing party, the witness and the deposition officer before the production date, citing the specific grounds (CCP 1985.3(g), 1985.6(f)(2)). Once the witness has notice of the motion, or has a nonparty's written objection, no production is required without a court order or an agreement.
What is the deadline to move to enforce a records subpoena after an objection?
Twenty days from service of the written objection, with a declaration showing a reasonable and good faith attempt at informal resolution. Only a consumer or employee who is not a party can serve that objection. For consumer records the motion is under CCP 1987.1 (CCP 1985.3(g)); for employment records CCP 1985.6(f)(4) names a motion under CCP 1987(c). Note separately that the 60-day limit in CCP 2025.480(b) applies to business records subpoenas as well, because records-only discovery is a deposition.
