Quick answer

To domesticate a subpoena in California, you have two routes under the Interstate and International Depositions and Discovery Act (Code Civ. Proc. §§ 2029.100–900). Submit your foreign subpoena with a Judicial Council SUBP-030 application and the filing fee to the clerk of the superior court in the county where discovery is sought, and the clerk promptly issues a California subpoena — or have a retained California attorney issue it directly under § 2029.350. No reciprocity is required; the issued subpoena is then personally served under § 1985.

California IIDDA Overview

Domesticating a Foreign Subpoena in California

California adopted the Uniform Interstate Depositions and Discovery Act as a statute — the Interstate and International Depositions and Discovery Act, Code of Civil Procedure §§ 2029.100–2029.900 (enacted by Stats. 2008, ch. 231; the domestication provisions operative January 1, 2010). Section 2029.700 calls it the “California version of the Uniform Interstate Depositions and Discovery Act.” It lets an out-of-state litigant obtain an enforceable California subpoena for depositions, testimony, records, and premises inspection — without a motion or a hearing.

California is one of the few states with two issuance routes. Under § 2029.300, you submit your foreign subpoena to the clerk of the superior court in the county where discovery is sought, together with a Judicial Council application (Form SUBP-030) and the filing fee, and the clerk promptly issues a matching California subpoena. Alternatively, under § 2029.350, a California-licensed attorney retained in the matter who receives the foreign subpoena may issue the California subpoena directly. Either way the request is not an appearance, and Served 123 LLC manages every step across all 58 counties.

Streamlined — but California has guardrails. The issued subpoena must be on the mandatory Judicial Council form, incorporate your foreign subpoena’s terms, carry all counsel information, and bear the out-of-state caption and case number (§ 2029.300(d)). Two California-specific points: the act also reaches subpoenas from foreign nations, not just other states; and under § 2029.300(e) (amended by SB 497, effective October 2025) the clerk will not issue a subpoena that targets gender-affirming health care or seeks sensitive-services information in a foreign penal civil action. We screen for both before filing.

Step-by-Step

How It Works in California

From intake to proof of service — exactly what happens on every California order.

1

Submit Your Foreign Subpoena

Use the order form above or email info@served123.com. Include the originating state (or country), the California county where discovery is sought, and your subpoena as a PDF. We confirm the matter qualifies under §§ 2029.100–900 — including the § 2029.300(e) limits — at intake.

2

California Subpoena Prepared

We prepare the mandatory Judicial Council forms — the SUBP-030 application plus the right subpoena (SUBP-035 business records, SUBP-040 personal appearance, or SUBP-045 appearance with documents) — incorporating your foreign subpoena’s terms and carrying all counsel information, the out-of-state caption, and the case number, exactly as § 2029.300(d) requires.

3

Clerk or Attorney Issuance

We obtain the issued California subpoena one of two ways: through the clerk of the superior court in the correct county on the SUBP-030 application with the § 70626 filing fee (the request is not an appearance), or — where you prefer — through retained California counsel issuing it directly under § 2029.350. Court costs are advanced and included.

4

Retrieval & Confirmation

Our authorized representative retrieves the issued California subpoena in person, confirms it is enforceable, and sends you a copy. No court appearance is required.

5

Personal Service

We dispatch through our California process-server network for personal service under § 1985 (§ 2029.400), with up to three diligent attempts per address. Witness fees — $35 per day plus $0.20 per mile for a personal appearance, or $15 for business records — are tendered as required and quoted in advance. For a person’s records, we serve the required consumer notice (§ 1985.3).

6

Proof of Service Delivered

You receive a signed, court-ready proof of service confirming completion in full compliance with California law — ready for immediate filing in your home-state case.

Two Ways In

California Gives You Two Ways to Issue

Most states have a single path to a domesticated subpoena. California has two — and the right one depends on whether you want a clerk-issued subpoena or a California attorney to issue it directly. We handle either, and screen every request against the state's issuance limits first.

§ 2029.300

Through the Court Clerk

Submit your foreign subpoena, a Judicial Council SUBP-030 application, and the § 70626 fee to the clerk of the superior court in the discovery county. The clerk promptly issues a matching California subpoena. The request is not an appearance, and no California attorney is required.

Clerk issues → 1–3 days
§ 2029.350

Through California Counsel

Have a retained attorney who is an active member of the California State Bar issue the subpoena directly on receiving your foreign subpoena — no clerk filing. Useful when you already have California counsel or need the subpoena in hand the same day.

Attorney issues → same day
§ 2029.300(e) · SB 497 (Oct 2025)

California Can Refuse to Issue — By Design

A recent shield provision bars the clerk from issuing a subpoena that is based on another state's law targeting gender-affirming health care, or that seeks sensitive-services information in a foreign penal civil action. It is a California-specific guardrail most vendors don't screen for — we check every request against § 2029.300(e) before filing, so nothing bounces at the counter.

Then & Now

Why the IIDDA Changed Everything

Before 2010, getting California discovery for an out-of-state case meant a commission and a noticed motion. The IIDDA replaced that with a clerk filing — or a California attorney's signature.

Before the IIDDA
  • Obtain a commission or letters rogatory from the home-state court
  • Notice a motion in a California superior court to compel
  • Retain California counsel to appear on the motion
  • Weeks of delay before a subpoena could issue
With the IIDDA
  • Submit the foreign subpoena + Form SUBP-030 to the superior court clerk
  • The clerk promptly issues — or a California attorney issues directly (§ 2029.350)
  • No motion, no hearing, no appearance
  • An enforceable California subpoena in days

Avoid the Rejection

Why California Domestications Get Bounced

A clerk's refusal to issue or a petition to quash can cost weeks and blow your discovery window. These are the California-specific errors we screen out before anything is filed.

Wrong county

Filed in the wrong one of California's 58 counties. We file with the superior court clerk where discovery is sought.

Wrong or missing Judicial Council form

The application and subpoena must be on the mandatory forms (SUBP-030 plus SUBP-035/040/045) and incorporate the foreign subpoena's terms. We prepare the right forms.

Consumer notice skipped

Subpoenas for a person's records trigger consumer-notice requirements under § 1985.3. Skipping them makes the subpoena defective. We serve the required notice.

Substituted service attempted

California requires personal service under § 1985 (§ 2029.400) — not mail or sub-service. We serve personally.

No witness fee tendered

Personal-appearance subpoenas require the $35-per-day and $0.20-per-mile fee; business-records subpoenas require the $15 fee. We tender them.

Issued where the act bars it

Under § 2029.300(e), California won't issue a subpoena that targets gender-affirming care or seeks sensitive-services data in a foreign penal action. We screen for it before filing.

Common Questions

California Subpoena Domestication FAQ

The questions attorneys ask most about domesticating a subpoena in California under the IIDDA.

Yes — as a statute. California enacted the Interstate and International Depositions and Discovery Act, Code of Civil Procedure §§ 2029.100–900 (Stats. 2008, ch. 231), with the domestication provisions operative January 1, 2010. Section 2029.700 expressly calls it the ‘California version of the Uniform Interstate Depositions and Discovery Act.’ It lets a foreign subpoena be domesticated without a motion or hearing.
There are two routes. (1) Clerk issuance under § 2029.300: submit your foreign subpoena, a Judicial Council SUBP-030 application, and the filing fee to the clerk of the superior court in the county where discovery is sought, and the clerk promptly issues a matching California subpoena. (2) Attorney issuance under § 2029.350: a retained California attorney issues it directly. Served 123 LLC handles either route end to end.
Yes. Under § 2029.350, if a party to the out-of-state case retains an attorney who is an active member of the California State Bar and that attorney receives the foreign subpoena, the attorney may issue the California subpoena directly — no clerk filing required. The issued subpoena still has to incorporate the foreign terms, carry all counsel information, bear the out-of-state caption and case number, and be on the Judicial Council form.
No. California adopted the uniform act without a reciprocity requirement. Any foreign subpoena issued by a court of record in another U.S. state, the District of Columbia, a territory, a federally recognized Indian tribe — or a foreign nation — can be domesticated under the Act.
The mandatory forms (effective January 1, 2010) are SUBP-030, Application for Discovery Subpoena in Action Pending Outside California, plus the matching subpoena: SUBP-035 (production of business records), SUBP-040 (deposition — personal appearance), or SUBP-045 (personal appearance and production of documents and things). No civil case cover sheet is required for the application.
Yes. Under § 2029.300(e) — amended by SB 497, effective October 2025 — the clerk will not issue a subpoena in two situations: (1) where the foreign subpoena is based on another state's law that interferes with a person's right to seek or obtain gender-affirming health care (or to let a child receive it), and (2) where it relates to a foreign penal civil action and would require disclosure of sensitive services information. We screen every request against § 2029.300(e) before filing.
California has no fixed objection deadline like the rule-based UIDDA states. A challenge is a petition to quash, modify, or for a protective order, filed in the superior court of the discovery county under § 2029.600 and governed by California's discovery rules (with § 1005 notice timing). For a person's records, the consumer-notice procedure under § 1985.3 also applies. A ruling is reviewable only by writ — no appeal (§ 2029.650).
For the clerk route, generally no — requesting issuance under § 2029.300 does not constitute an appearance, so no pro hac vice is needed to issue and serve. The attorney route under § 2029.350 uses a California attorney by definition. Local counsel may be needed only if a petition to quash, modify, or enforce is litigated. Served 123 LLC handles the issuance and service either way.
Under § 2029.400, a subpoena issued under the Act must be personally served in compliance with California law, including Code of Civil Procedure § 1985 — not by mail or substituted service. Served 123 LLC uses experienced California process servers statewide and returns a signed, court-ready proof of service.
The clerk's issuance fee under Government Code § 70626 is $45. Witness fees: a personal-appearance subpoena carries $35 per day plus $0.20 per mile (Gov. Code § 68093); a business-records subpoena carries a $15 witness fee (Evid. Code § 1563). Served 123 LLC advances these and quotes them before service.
Under § 2029.300(d) the issued subpoena must (1) incorporate the terms of the foreign subpoena, (2) contain or be accompanied by the names, addresses, and telephone numbers of all counsel of record and any unrepresented party, (3) bear the caption and case number of the out-of-state case, (4) state the name of the issuing court, and (5) be on the Judicial Council form.
Yes — that is the ‘International’ part of the name. Under § 2029.200, a ‘foreign jurisdiction’ includes both another U.S. state and a foreign nation. A subpoena issued by a court of record abroad can be domesticated in California through the same process, subject to the § 2029.300(e) limits.
A domesticated California subpoena is enforceable in the superior court of the discovery county. Under § 2029.600, a petition to enforce (or to quash or modify) is filed there and governed by California's discovery rules, which carry sanctions and contempt for failure to obey without adequate excuse (§ 2029.500). A ruling is reviewable only by extraordinary writ to the court of appeal (§ 2029.650). Proper personal service and a court-ready proof of service are what make enforcement possible.
