California Subpoena Duces Tecum (SDT): Records Subpoenas Under CCP § 2020.410

A subpoena duces tecum commands a person to produce documents. In California civil discovery the version you order most is the deposition subpoena for production of business records under Code of Civil Procedure § 2020.410, which most offices call a records subpoena or an SDT. We prepare it, compute the dates, tender the statutory witness fee, and serve the custodian. Production cannot be commanded sooner than 20 days after issuance or 15 days after service, whichever falls later. If the records belong to a consumer or an employee, a notice goes out first, adding at least 10 more days in front of everything.

Since 1999, California law firms have handed us the instrument and the deadline and let us work backward from it.

Duces tecum, records subpoena, SDT — what you are actually ordering

Duces tecum is Latin for “bring with you.” Any subpoena commanding production of documents is a subpoena duces tecum, so a records subpoena is a species of SDT, not an alternative to one. What § 2020.020 recognizes is three deposition subpoenas:

• Testimony only. CCP § 2020.310. Judicial Council form SUBP-015.
• Business records only. CCP §§ 2020.410–2020.440. Form SUBP-010, mandatory use. This is what people mean by “records subpoena” or “SDT” nine times out of ten.
• Testimony and production. CCP § 2020.510. Form SUBP-020.

Trial and hearing subpoenas sit outside that chapter, under CCP § 1985: SUBP-001 for testimony, SUBP-002 when you also want documents. SUBP-002 is the only form the Judicial Council titles “(Duces Tecum),” which is part of why the vocabulary drifts. Some offices say SDT and mean the records-only subpoena; others mean any document subpoena. Tell us which you want, or tell us what you need to prove and who holds the paper.

One rule shapes the approach: under § 2020.010(b) a deposition subpoena is the only way to get discovery from a nonparty. This page carries the instrument-and-procedure detail behind our California subpoena services hub.

When you need this

• Medical records from a treating provider. The most common records subpoena in the state, and the one with the most ways to fail. See how to subpoena medical records in California.
• Bank, brokerage, insurer, accountant, or school records. Classic § 1985.3 custodians, on a list that is closed and enumerated.
• A personnel file from a current or former employer. Former employers count, and so do labor unions. Different statute, different notice: § 1985.6.
• Telephone records from a public utility. A notice alone will not do here. These need the consumer’s signed consent.
• Agency records containing personal information. CCP § 1985.4 pulls the § 1985.3 machinery across. Peace officer personnel records are carved out and cannot be reached this way at all.
• A live custodian with the originals. Nobody appears by default. Getting a person in the room takes specific language.
• A case pending outside California. A domestication problem before it is a service problem.

How the process works

Step 1 — You tell us the instrument and the date, we draft it

Order through the client portal or by phone. We need the caption, the custodian, the records description, and your production date. Send any signed consumer authorization with the order, since it changes the sequence. Records get described item by item, or by reasonably particularizing each category, per § 2020.410(a). We confirm the mandatory boldface legend appears on the face of the subpoena and that your production date clears the § 2020.410(c) floor.

Step 2 — Notice first, then the custodian

A sequence, not a bundle. The consumer or employee is served at least 10 days before the production date and at least five days before we go near the custodian, plus the CCP § 1013 extension for mail. We use SUBP-025, the mandatory Judicial Council form. Then we serve the designated custodian, carrying either the proof of service of that notice or the signed authorization, as § 2020.410(d) requires. A records-only subpoena also goes out with a $15 check attached, whether or not anyone demanded it.

Step 3 — Production, tracking, delivery

The custodian delivers a legible copy plus the § 1561 affidavit to the deposition officer named in the subpoena, within 15 days of receipt in a civil action. Practice varies far more than the statute does, and we know which hospital systems need a portal submission and which insurers hold for payment. A certificate of no records is a statutory answer under Evidence Code § 1561(b), usually meaning the entity or the date range needs adjusting. Records reach you once the deposition officer has them, and any other party can buy a copy for six months after the case settles under § 2020.440. Copying, indexing, and volume production are handled by our records retrieval team for law firms.

The California legal framework

The good cause affidavit, and when you do not need one

CCP § 1985(b), on the pre-trial SDT:

“A copy of an affidavit shall be served with a subpoena duces tecum issued before trial, showing good cause for the production of the matters and things described in the subpoena, specifying the exact matters or things desired to be produced, setting forth in full detail the materiality thereof to the issues involved in the case, and stating that the witness has the desired matters or things in his or her possession or under his or her control.”

Four conjunctive requirements. “The records are relevant” meets the first and none of the rest, and in Lee v. Superior Court (2009) 177 Cal.App.4th 1108 subpoenas failing to state the factual basis of materiality were held ineffective. Under CCP § 1987.5, service is invalid unless the affidavit goes with the subpoena.

Discovery subpoenas need no such affidavit, which is where most writing on this subject goes wrong. Section 2020.410(c) says a records-only subpoena “need not be accompanied by an affidavit or declaration showing good cause,” § 2020.510(b) says the same for the deposition-plus-production subpoena, and Terry v. SLICO (2009) 175 Cal.App.4th 352 confirms it.

Notice to consumer, CCP § 1985.3

If the records identify a person and the custodian sits on the § 1985.3 list, that person gets notice and a chance to object before the custodian is served. Two clocks run from the same event to different destinations: at least 10 days from service on the consumer to the production date, and at least five days from service on the consumer to service on the custodian. CCP § 1013 extends both for mail, and not by a flat five: five days within California, 10 days elsewhere in the United States, 20 days across the border.

Who counts matters too. A consumer is any individual, partnership of five or fewer persons, association, or trust, never a corporation and never a six-partner firm. Get the notice wrong and § 1985.3(k) applies:

“Failure to comply with this section shall be sufficient basis for the witness to refuse to produce the personal records sought by a subpoena duces tecum.”

The custodian simply declines, no court order needed. In Sasson v. Katash (1983) 146 Cal.App.3d 119, defective notice justified excluding the documents at trial.

Employment records, CCP § 1985.6

Same architecture, different statute. The custodian is a current or former employer, or a labor organization, and “employee” reaches anyone the subpoenaed union has represented. The notice carries four required items instead of three, including a statement that the records may be protected by a right of privacy. Any employee may move to quash, with no party limitation in the text, and you enforce over an objection under § 1987(c), not § 1987.1.

Timing, counted backward from your trial date

Three rules stack, and calendars usually account for only the first.

1. The production floor. No sooner than 20 days after issuance or 15 days after service, whichever is later. Compute both; the later date governs.
2. The notice clock. Ten days plus any § 1013 extension in front of production, five days plus extension in front of custodian service.
3. The discovery cutoff. CCP § 2024.020 gives you until the 30th day before the date initially set for trial, and a continuance does not reopen discovery. Expert discovery has its own 15-day and 10-day counts under § 2024.030.

Stack them and the last safe issue date lands weeks earlier than most people assume. Two more traps. Section 2025.270(c) puts a deposition at least 20 days after issuance where you also subpoena consumer or employment records from that deponent. And the custodian’s own 15-day deadline under Evidence Code § 1560(b)(2) runs from receipt, which is a separate clock running the other way.

The deposition officer requirement

This is why a records subpoena needs a third party at all. Section 2020.420:

“The officer for a deposition seeking discovery only of business records for copying under this article shall be a professional photocopier registered under Chapter 20 (commencing with Section 22450) of Division 8 of the Business and Professions Code … This deposition officer shall not be financially interested in the action, or a relative or employee of any attorney of the parties.”

A licensing requirement, not a preference. Your paralegal cannot fill the role. Section 2020.430(a) closes the loop: the custodian delivers to the deposition officer and only to the deposition officer, never straight to the requesting attorney. Objections to the officer’s qualifications are waived unless raised before the production date, which cuts both ways. Our California deposition officer service covers that role in full.

Fees and tenders

• Records-only subpoena: $15 with service, whether or not demanded. CCP § 2020.230(b), via Evidence Code § 1563(b)(6).
• Deposition subpoena requiring attendance: witness fee and mileage, again whether or not demanded. CCP § 2020.230(a).
• Trial or hearing subpoena: fees tendered only if the witness demands them. CCP § 1987(a).
• Statutory witness fee: $35 per day, $0.20 per mile both ways. Government Code § 68093.

Statutory figures, not our rates. Evidence Code § 1563(b) explains most stalled productions: a witness may demand payment on delivery and owes nothing until paid.

Objections, holds, and motions to quash

A party consumer moves to quash or modify under § 1987.1 before the production date, on five days’ notice to the witness and the deposition officer. A nonparty consumer instead serves a written objection citing specific grounds, and files nothing. Either route stops production cold, and nobody may produce afterward absent a court order or the agreement of everyone affected. It is self-executing: no order to stop it, an order to start it again. You then have 20 days from service of the objection to move to enforce, with a meet-and-confer declaration.

On privacy the governing framework is Williams v. Superior Court (2017) 3 Cal.5th 531 — the three Hill v. NCAA threshold elements, then balancing, with a compelling interest required only for obvious invasions of interests fundamental to personal autonomy. Anything still stating compelling interest as a universal requirement is describing pre-2017 law. What narrows records in practice is Britt v. Superior Court (1978) 20 Cal.3d 844: a personal-injury plaintiff does not put a lifetime medical history in issue. More on that: motion to quash a subpoena in California.

Personal appearance, out-of-state actions, and federal cases

Evidence Code § 1564 keeps personal attendance optional unless the subpoena carries its exact statutory clause requiring the custodian to appear with the originals. Tell us at order time, and see deposition subpoena for personal appearance.

An action pending in another state reaches a California witness through the Interstate and International Depositions and Discovery Act, CCP §§ 2029.100–2029.900, on the SUBP-030 through SUBP-050 forms. Section 2029.300 was amended effective 13 October 2025 and now bars issuance in two defined circumstances, so a foreign subpoena that was routine two years ago deserves a second look. See our out-of-state subpoena in California page for that process. Federal subpoenas run on FRCP 45 instead, with different timing and no notice-to-consumer rule, and several courts want an informal discovery conference before a discovery motion is heard. Check the local rules alongside our summary of California subpoena service rules.

Questions attorneys and paralegals ask

Who can serve a subpoena in California?

Any person. CCP § 1987(a) says “the service may be made by any person,” and § 2020.220(b) repeats it for deposition subpoenas. The rule requiring a server over 18 who is not a party comes from § 414.10 and applies to the summons only. It does not carry over to subpoenas.

Does a California records subpoena need an affidavit of good cause?

No. CCP § 2020.410(c) states that a records-only deposition subpoena “need not be accompanied by an affidavit or declaration showing good cause.” Section 2020.510(b) says the same for a subpoena that also commands testimony. The good cause affidavit under § 1985(b) belongs to the pre-trial and trial SDT.

How many days before production must a notice to consumer be served?

At least 10 days before the production date stated in the subpoena, plus the CCP § 1013 extension if you serve by mail, which is five days in state. Separately, the consumer must be served at least five days before the custodian. Both clocks have to clear.

What makes a records subpoena defective?

Serving the custodian before or on the same day as the consumer. Omitting the proof of service or authorization from the custodian’s packet. A production date inside the § 2020.410(c) floor. A home-made notice instead of SUBP-025. A missing boldface legend. Naming an unqualified deposition officer.

Do I have to pay a witness fee with a records subpoena?

Yes, and you pay it without being asked. CCP § 2020.230(b) requires service of a records-only subpoena to be accompanied by the Evidence Code § 1563(b)(6) fee, currently $15, “whether or not demanded by the deponent.” A trial subpoena differs: fees are tendered there only if the witness demands them.

What happens when the consumer objects?

Production stops immediately. No witness or deposition officer may produce after a written objection or notice of a motion to quash, absent a court order or agreement of everyone affected. You then have 20 days from service of the objection to move to enforce, and the motion needs a meet-and-confer declaration.
