Summary: When a witness or document that could decide your business lawsuit sits in another country, your subpoena can’t reach it. A letter rogatory is the formal way the court handling your case asks a foreign court for help. This guide covers when you need one, how the process works, what it costs, and how to keep your request from being rejected.
Key Takeaways:
- A court-to-court request: A letter rogatory asks a foreign court to gather evidence for your case, because a U.S. court’s authority stops at the border.
- The treaty route is faster: When the other country belongs to the Hague Evidence Convention, a letter of request usually beats the slower diplomatic process.
- Plan for delay: The U.S. State Department warns that a traditional letter rogatory can take a year or more.
- Specificity wins: Foreign courts reject requests that read like fishing expeditions, so name the exact documents and witnesses.
- It runs both ways: Federal law also lets foreign litigants ask a U.S. court for evidence located here.
A Florida company sues its overseas supplier for breach of contract. The signed agreements, the shipping records, the emails that show what was promised: all of it sits on servers and in offices abroad. Your litigation team drafts a subpoena, then hits the wall every cross-border case runs into. A U.S. subpoena has no force outside the United States.
A letter rogatory is one of the few tools that reaches past that wall. Nearly 70 countries belong to the Hague Convention on the Taking of Evidence Abroad, the treaty that often decides whether you can avoid the slow diplomatic route. Which path fits your case can mean the difference between evidence that arrives in months and evidence that takes years.
What Is a Letter Rogatory?
A a formal request from the court handling your lawsuit to a court in another country, asking it to collect evidence for your case. It works through comity, the respect one nation’s courts extend to another’s, because a U.S. judge holds no authority abroad.
Think of it as one judge writing to another. Your court isn’t issuing an order, because it can’t command a foreign court to do anything. It’s making a request, and the foreign court decides whether to honor it. That single fact shapes everything that follows: the timeline, the cost, and the uncertainty you take on.
Letter Rogatory vs. Letter of Request: What’s the Difference?
A letter rogatory is the diplomatic, comity-based tool you use when no treaty applies. A letter of request is the instrument used under the Hague Evidence Convention: treaty-backed, faster, and more predictable. People use the two terms loosely, but the practical gap is speed and certainty.
| Method | When you use it | Typical speed |
| Letter rogatory | No treaty between the U.S. and the foreign country | A year or more |
| Letter of request (Hague Evidence Convention) | The other country is a Hague member | Often months, not years |
| Direct discovery under U.S. rules | A U.S. court already has jurisdiction over the party | Fastest, when available |
It’s whether you need one at all. If your evidence sits in a Hague country, the letter of request is almost always the better road.
When Do You Need a Letter Rogatory?
When the country holding your evidence hasn’t joined the Hague Evidence Convention, or when the Convention’s channels won’t deliver what you need. If that country is a Hague member, a letter of request usually moves faster.
The first thing an international litigator checks is membership: whether the country sits on the Hague list. If it does, you likely have a treaty route. If it doesn’t, the letter rogatory is often your only formal option.
There’s a second wrinkle. Some Hague countries have refused U.S.-style pretrial document discovery, so even a treaty member can push you back toward the older process for certain business records.
How the Letter Rogatory Process Works, Step by Step
A letter rogatory moves through a fixed sequence. Each stage adds time, which is why starting early matters so much.
1. Confirm it’s the right tool
Your attorney checks whether a treaty route is faster or available before committing. A letter rogatory is the fallback, not the default starting point.
2. Draft the request and get it issued
Your attorney drafts the request and a supporting motion explaining why the evidence matters. A U.S. judge, not a clerk, then signs and seals it.
3. Translate and authenticate
The full package gets translated into the foreign country’s official language by a certified translator. Many countries also require an apostille or consular authentication on top.
4. Transmit through diplomatic channels
The request travels from your court to the U.S. State Department, then to the foreign ministry, then down to the local court. Federal law authorizes this transmittal route. This is the slow stage.
5. The foreign court executes and returns the evidence
A foreign judge reviews the request and decides whether and how to carry it out under local law. The collected evidence then returns the same way it came.
How Long Does a Letter Rogatory Take, and What Does It Cost?
Plan for a year or more. The U.S. State Department’s own guidance warns that a traditional letter rogatory can take that long, sometimes longer. A Hague letter of request is usually faster, often landing in months instead of years.
Cost is harder to pin down, because it depends on the country and the evidence. Four things drive it: certified translation, foreign local counsel, authentication fees, and the months the case stays open. Translation alone can rival attorney fees on a large document request. None of that is a reason to wait. The longer you sit on it, the tighter your discovery deadline gets.
Why Letters Rogatory Get Rejected, and How to Avoid It
A foreign court can refuse the request, and plenty do. In our international litigation practice, the rejections almost always trace back to the same short list of mistakes.
The request reads like a fishing expedition. Foreign courts won’t help you go looking for evidence that might exist. Name the specific contract. Name the specific witness. Broad “all communications” requests get denied.
The country won’t honor U.S.-style discovery. Many Hague members have formally opted out of broad pretrial document requests. Draft narrowly, and tie each item to a fact actually in dispute.
It was filed too late. A request that needs a year can’t be started two months before your discovery cutoff. Begin as soon as foreign evidence looks likely. The fix for all three is the same: be specific, and start early.
Getting Evidence the Other Direction: When a Foreign Case Needs U.S. Evidence
The process runs both ways. If you’re in a foreign lawsuit and the evidence is in the United States, federal law lets you ask a U.S. court to order testimony or documents. The evidence doesn’t even have to be discoverable under the foreign court’s own rules.
That power comes from 28 U.S.C. § 1782, and the Supreme Court read it broadly in Intel Corp. v. Advanced Micro Devices, Inc., 542 U.S. 241 (2004). One limit is worth knowing. In ZF Automotive US, Inc. v. Luxshare, Ltd., 596 U.S. 619 (2022), the Court ruled unanimously that private commercial arbitration doesn’t qualify, so a private arbitration panel abroad can’t use this tool.
Florida Cases: Where Your Request Starts and Why Experienced Counsel Matters
A letter rogatory issues from the court where your case is pending. For many Florida businesses, that’s a state circuit court or one of the three federal trial courts: the Middle, Southern, or Northern District of Florida. Under Florida Rule of Civil Procedure 1.300, a state circuit court can issue a letter rogatory for a deposition taken in another country, on application and notice.
The drafting has to satisfy two legal systems at once: U.S. requirements and the foreign court’s expectations. A U.S. national living abroad can also be subpoenaed directly under a separate federal statute. If your commercial dispute needs foreign evidence, getting any of this wrong usually means starting over, which is exactly the delay you can’t afford.
FAQs About Letters Rogatory
Can I subpoena documents from a foreign company in a U.S. lawsuit?
If the foreign company is a party to your case and the U.S. court has jurisdiction over it, the court can often order production directly, with no letter rogatory needed. If the company is a non-party located abroad, you usually need a letter rogatory or a Hague letter of request to reach its records.
How do I get evidence from an overseas business for a breach of contract case?
Start by checking whether the country belongs to the Hague Evidence Convention. If it does, a letter of request is usually the faster route. If it doesn’t, a letter rogatory asks the foreign court for the contracts, emails, or testimony you need to prove the breach.
Is a letter rogatory or the Hague Convention faster?
The Hague Convention is almost always faster. A letter of request under the Convention often resolves in months, while a traditional letter rogatory can run a year or more through diplomatic channels. Speed is the main reason to use the treaty route whenever the other country is a member.
Can you use a letters rogatory in international arbitration?
It depends on the type of arbitration. A letter rogatory can reach evidence for some foreign court and investor-state proceedings. In 2022, though, the Supreme Court ruled that private commercial arbitration panels don’t qualify for U.S. court assistance, so that route is closed for purely private arbitrations.
