Text sizeJump to: (a) (b) (c) (d) (e)

(a) Any party may obtain discovery by taking an oral deposition, as described in Section 2025.010, in a foreign nation. Except as modified in this section, the procedures for taking oral depositions in California set forth in Chapter 9 (commencing with Section 2025.010) apply to an oral deposition taken in a foreign nation.
(b) If a deponent is a party to the action or an officer, director, managing agent, or employee of a party, the service of the deposition notice is effective to compel the deponent to attend and to testify, as well as to produce any document, electronically stored information, or tangible thing for inspection, copying, testing, or sampling.
(c) If a deponent is not a party to the action or an officer, director, managing agent or employee of a party, a party serving a deposition notice under this section shall use any process and procedures required and available under the laws of the foreign nation where the deposition is to be taken to compel the deponent to attend and to testify, as well as to produce any document, electronically stored information, or tangible thing for inspection, copying, testing, sampling, and any related activity.
(d) A deposition taken under this section shall be conducted under the supervision of any of the following:
(1) A person who is authorized to administer oaths or their equivalent by the laws of the United States or of the foreign nation, and who is not otherwise disqualified under Section 2025.320 and subdivisions (b) to (f), inclusive, of Section 2025.340.
(2) A person or officer appointed by commission or under letters rogatory.
(3) Any person agreed to by all the parties.
(e) On motion of the party seeking to take an oral deposition in a foreign nation, the court in which the action is pending shall issue a commission, letters rogatory, or a letter of request, if it determines that one is necessary or convenient. The commission, letters rogatory, or letter of request may include any terms and directions that are just and appropriate. The deposition officer may be designated by name or by descriptive title in the deposition notice and in the commission. Letters rogatory or a letter of request may be addressed: “To the Appropriate Judicial Authority in [name of foreign nation].” WESTLAW © 2026 Thomson Reuters.

Plain-English Summary

Taking testimony abroad raises the same basic problem as taking it in another state, only with a foreign legal system instead of a sister state's. This section lets a party obtain discovery by deposing a witness in a foreign nation, applying the same Chapter 9 oral-deposition procedures used in California except as modified here. As with an out-of-state deposition, compulsion turns on the deponent's relationship to a party: if the deponent is a party, or an officer, director, managing agent, or employee of one, serving the deposition notice is enough on its own to require attendance, testimony, and production. If the deponent has no such connection to a party, the noticing party instead has to rely on whatever process the foreign nation's own law makes available to compel participation.

Running the deposition itself requires someone with recognized authority to administer the oath, and the section gives three options: a person authorized under United States or foreign law to do so, a person appointed under a commission or letters rogatory, or anyone all the parties agree on. Getting that authority in place is where the court comes in. On a party's motion, the court issues whichever of a commission, letters rogatory, or a letter of request it decides is necessary or convenient, and that instrument can include whatever terms and directions fit the situation, including addressing letters rogatory or a letter of request to the appropriate judicial authority in the foreign nation named, without more. Letters rogatory is the older, more formal diplomatic-style request between courts; a letter of request and a commission are more direct and typically faster where the foreign nation's law allows them.

Frequently Asked Questions

Can a party depose a witness located in a foreign country for a California lawsuit?

Yes. Section 2027.010 lets a party obtain discovery by taking an oral deposition in a foreign nation, using the same procedures that govern depositions in California except as modified here.

Does a California deposition notice compel a foreign witness with no ties to a party to appear?

No. When the deponent isn't a party or an officer, director, managing agent, or employee of one, the noticing party must use the compulsion process available under the foreign nation's own laws.

What is the difference between a commission and letters rogatory?

Both are court-issued instruments that authorize or request a foreign deposition, but letters rogatory is the more formal, traditionally diplomatic request addressed to a foreign judicial authority, while a commission or letter of request is typically a more direct route where the foreign nation's law permits it.

Who decides whether a commission or letters rogatory is needed for a foreign deposition?

The court where the action is pending, on the motion of the party seeking to take the deposition, based on what it determines is necessary or convenient.
