The Complete Guide to 28 U.S.C. § 1782 Discovery

Section 1782 is one of the most powerful — and underused — tools in cross-border litigation. It lets a party in a foreign case ask a U.S. federal court to compel a person or company found in the United States to hand over evidence. This guide explains, in plain English, what the statute requires, where its limits are after the Supreme Court's 2022 decision, and how an application actually works.

1. What § 1782 is — in one paragraph

28 U.S.C. § 1782 is a federal statute that allows a U.S. district court to order a person who "resides or is found" in that district to produce documents or give testimony "for use in a proceeding in a foreign or international tribunal." The request can be made by the foreign tribunal itself or — far more commonly — by any "interested person," which usually means a party to the foreign case. In short: if the evidence you need for a case abroad sits with someone in the United States, § 1782 is the mechanism for reaching it.

2. Why it's so powerful

U.S. discovery is famously broad compared with most of the world. Many foreign legal systems give parties little ability to force an opponent — let alone a third party such as a bank, an accounting firm, or a tech platform — to turn over internal documents or sit for a deposition. Section 1782 lets a foreign litigant tap into the full breadth of U.S. discovery, including:

• Documents and records held by U.S. companies and individuals;
• Banking and financial records that can trace money, transfers, and hidden assets;
• Electronic data from technology, communications, and cloud providers headquartered in the U.S.;
• Sworn deposition testimony from witnesses located in the United States.

Because so many global companies, banks, and platforms are "found" in the United States, § 1782 often reaches evidence that would be impossible to obtain through the courts of the country where the dispute is actually being fought.

3. The three statutory requirements

Before a court will even consider granting relief, an applicant must clear three threshold ("statutory") requirements:

(a) The target "resides or is found" in the district

The person or company from whom you want evidence must reside or be found within the federal judicial district where you file. For an individual, that usually means they live there or are physically present. For a company, courts generally look at where it is incorporated, headquartered, or systematically doing business. You file in the district that fits the target — which is why identifying the right respondent and the right court matters from day one.

(b) The discovery is "for use" in a foreign proceeding

The evidence must be "for use" in a proceeding before a foreign or international tribunal. You do not need a U.S. case — the whole point is that the case is abroad. You generally need to show that you have some ability to use the evidence in that foreign proceeding, and that the proceeding is either pending or, as discussed below, within reasonable contemplation.

(c) The applicant is an "interested person"

The request must come from the foreign tribunal or from an "interested person." The Supreme Court has read "interested person" broadly: it plainly includes the litigants in the foreign case, but it can reach anyone with significant participation rights or a reasonable interest in obtaining the court's assistance. A party to the foreign dispute is the classic interested person.

4. The arbitration limit after ZF Automotive

This is the single most important recent development, and it trips up many applicants. In ZF Automotive US, Inc. v. Luxshare, Ltd. (2022), the U.S. Supreme Court held that a "foreign or international tribunal" under § 1782 means a governmental or intergovernmental adjudicative body — not a private one.

The practical takeaways:

• Foreign court litigation qualifies. A civil or commercial lawsuit in a foreign national court is squarely within § 1782.
• Foreign government and regulatory proceedings can qualify. These are governmental tribunals.
• Private international commercial arbitration generally does not qualify. A purely private arbitral panel is not a governmental tribunal, so § 1782 is generally unavailable to gather evidence for it.

If your dispute is in private arbitration, that is not necessarily the end of the road — there may be a related or parallel foreign court proceeding (for example, to enforce or set aside an award, or a separate civil action) that does qualify. The analysis is fact-specific, which is exactly the kind of thing worth checking before you file.

5. "Reasonably contemplated" proceedings

The foreign proceeding does not have to be filed yet. Courts have long accepted that § 1782 can be used where the foreign proceeding is "within reasonable contemplation" — that is, more than a vague possibility. You generally need to show a concrete, good-faith plan to bring the case, not merely a hope that you might someday sue. This lets parties gather the evidence they need to decide whether and how to proceed abroad.

6. The four Intel discretionary factors

Even when the three statutory requirements are met, granting § 1782 relief is discretionary. In Intel Corp. v. Advanced Micro Devices, Inc. (2004), the Supreme Court set out four factors that courts weigh:

1. Is the target a participant in the foreign proceeding? If the evidence is held by someone who is not a party abroad (a third-party bank, vendor, or platform), that cuts in favor of § 1782 — because the foreign court may have no power to reach them. If the target is already a party, the foreign court can often order discovery itself.
2. Is the foreign tribunal receptive to U.S. assistance? Courts consider whether the foreign court would welcome — or resent — the evidence. Most do not object; clear hostility weighs against relief.
3. Is the request an attempt to circumvent foreign limits? Courts look at whether the application is a good-faith request or an effort to dodge the foreign jurisdiction's proof-gathering restrictions or other policies.
4. Is the request unduly intrusive or burdensome? Overbroad or harassing requests get trimmed or denied. Narrow, well-targeted requests fare far better.

Good § 1782 practice is really about positioning your application to win on these factors: targeting a non-party who holds the evidence, keeping requests tight and proportionate, and showing the foreign court will use what you obtain.

7. The process, step by step

Here is what a typical § 1782 application looks like from start to finish:

1. Identify the target and the right court. Pin down who holds the evidence and which federal district they are "found" in. That district is where you file.
2. Build the application package. A § 1782 application is usually filed as a miscellaneous matter and typically includes: a petition explaining why you qualify; a supporting declaration (often from your foreign counsel) describing the foreign case, the evidence needed, and how it will be used; a proposed order; and a proposed subpoena specifying the exact documents or deposition topics.
3. File ex parte. Applications are commonly filed ex parte — meaning you present them to the judge without the other side initially appearing. Because of this, a judge can often authorize the subpoena relatively quickly.
4. Serve the subpoena. Once the court authorizes it, the subpoena is served on the target under the federal discovery rules (it functions much like a Rule 45 subpoena).
5. Respond to any challenge. The target — or an opponent who learns of the order — can move to quash or modify the subpoena. This is where the Intel factors are litigated, so a well-built application pays off.
6. Obtain and use the evidence. Documents are produced, data is gathered, or the deposition proceeds — and the evidence goes into your foreign case.

8. Common ways people use § 1782

• Foreign litigation support. Getting documents or testimony from a U.S.-based party, witness, or third party for an ongoing or planned lawsuit abroad.
• Asset tracing and judgment enforcement. Using U.S. banking and financial records to find assets, follow transfers, and enforce a foreign judgment. (See our article on enforcing a foreign judgment.)
• Fraud and asset recovery. Tracing where money went when a counterparty or debtor has moved funds through U.S. institutions.
• Intellectual property disputes. Obtaining evidence from a U.S. company relevant to a foreign patent, trademark, or trade-secret case.
• Family, inheritance, and matrimonial matters. Reaching financial records held in the U.S. that are relevant to a proceeding abroad.
• Regulatory and government proceedings. Supporting a foreign governmental or regulatory action with U.S.-located evidence.

9. What evidence you can actually get

Section 1782 reaches the same categories of evidence as ordinary U.S. discovery:

• Documents — contracts, communications, internal records, and reports;
• Financial and banking records — account statements, wire and transfer records, and know-your-customer files (subject to the bank's own legal obligations);
• Electronically stored information — emails, messages, files, logs, and other data from U.S. providers;
• Deposition testimony — sworn, recorded answers from a witness located in the United States.

Requests must be reasonably targeted. Privileges (such as attorney-client privilege) and the respondent's own legal obligations still apply, and an overbroad request invites a motion to quash.

10. Timeline, cost, and what to expect

Timelines vary widely by district, by how cooperative the target is, and by whether anyone fights the subpoena. An uncontested ex parte application may be authorized in a matter of weeks; a contested motion to quash can extend the process by months. Because § 1782 is procedurally efficient at the front end, it is often faster and cheaper than trying to obtain the same evidence through letters rogatory or the foreign court itself.

What helps most: a precisely identified target, a narrow and well-justified request, a clear explanation of the foreign proceeding, and a declaration from foreign counsel confirming the evidence will be usable. Getting these right at the outset is the difference between a smooth authorization and a drawn-out fight.

11. Frequently asked questions

Do I need a U.S. lawsuit to use § 1782?

No. The point of § 1782 is to obtain U.S. evidence for a case abroad. You need a qualifying foreign proceeding that is pending or reasonably contemplated — not a U.S. case.

Can I use § 1782 for an international arbitration?

Generally not for a private commercial arbitration, after ZF Automotive (2022). Foreign court and government proceedings qualify. A related foreign court action connected to the arbitration may still provide a path — it depends on the facts. See our article on arbitration and § 1782.

Who can file?

The foreign tribunal or an "interested person" — typically a party to the foreign proceeding. The term is read broadly. See who can apply.

Where do I file?

In the U.S. federal district court where the person or company holding the evidence "resides or is found."

How fast is it?

An uncontested ex parte application can be authorized in weeks; a contested one takes longer. It is usually faster than the foreign-court or letters-rogatory route.

Will the other side find out?

The initial application is often ex parte, but once a subpoena is authorized and served, the target knows and may challenge it. § 1782 is a discovery tool, not a secret one.

Is there any guarantee I'll get the evidence?

No. Relief is discretionary under the Intel factors, and a target can move to quash. A well-built, narrowly tailored application materially improves your odds.
