If you need to serve process in England or Wales, it looks like the easiest job in the world. The documents are already in English, the legal system shares common-law roots with ours, and English courts are familiar with American litigation. Yet a defective service can undo months of work once the defendant’s counsel starts looking at how it was done.
The Hague Convention applies when you serve process in England
The United Kingdom is a party to the Hague Service Convention, so any U.S. case that requires documents to be sent to England or Wales for service must use one of the methods the Convention allows. It doesn’t matter which U.S. court is hearing the case.
One point that surprises people: “the UK” isn’t a single destination for service. The Foreign Secretary is the UK’s designated Central Authority, and separate additional authorities handle England and Wales, Scotland, and Northern Ireland. A defendant in Edinburgh or Belfast goes through a different office from one in London or Cardiff.
Route 1: The Central Authority (Article 5)
For England and Wales, a formal request goes to the Senior Master at the Royal Courts of Justice in London.
- Complete Form USM-94, the Convention’s model request. It must be complete and accurate, and signed by an authority or judicial officer competent under U.S. law, such as the court clerk or the attorney of record.
- Attach the documents to be served, in duplicate.
- Check the language. The UK requires documents in English. If your defendant doesn’t read English well, translate anyway: a defendant served with papers they can’t understand has grounds to challenge service under U.S. due-process principles, whatever the Convention allows.
- Send the request and wait. Expect several months before the certificate of service comes back.
This route produces an official certificate under Article 6, which is its main advantage. The drawbacks are time, and a real risk with individual defendants: a person who avoids or ignores delivery can leave you with an unsuccessful return months later.
Route 2: Serve process in England through a solicitor (Article 10)
This is usually the best way to serve process in England, for companies as well as individuals, and it’s much faster.
The Convention allows service directly through competent persons in the destination country, unless that country objects. The UK hasn’t objected, but its position comes with an important condition. The UK Foreign Office has confirmed that its declaration doesn’t stop a party to a foreign proceeding, or their lawyer, from serving directly through a competent person such as a solicitor.
In practice, the process server should be instructed through an English solicitor. A process server hired directly from the United States, with no solicitor involved, risks service that doesn’t fit the UK’s stated position, and that’s exactly the kind of defect opposing counsel looks for.
Done properly, this route typically completes service in weeks rather than months. You receive a sworn affidavit of service, and personal delivery removes the risk of an unsigned or refused mailing.
Route 3: Service by mail (Article 10(a))
Mail service is technically available. In 2017, in Water Splash, Inc. v. Menon, the U.S. Supreme Court confirmed that the Convention permits service by mail where the destination country hasn’t objected and the law of the forum allows it.
It’s still rarely the best option. Proof of delivery is weaker, a signature from someone at the address doesn’t prove the defendant received the papers, and many U.S. courts look harder at mail service when a default judgment is at stake. If the case matters, use personal service.
Serving a subpoena? That’s a different process
Service doesn’t compel evidence
Serving a U.S. subpoena on a witness in England won’t force them to testify or produce documents. To obtain evidence, you need a letter of request under the Hague Evidence Convention, which asks an English court to compel the evidence under its own powers.
It’s a separate procedure with its own requirements and timelines. See our guide to taking evidence abroad.
Which route to use to serve process in England
| Situation | Recommended route |
|---|---|
| Individual defendant | Process server instructed by a solicitor |
| Company with a registered office | Solicitor-instructed process server, or the Central Authority if time allows |
| A judgment may need enforcing in England later | Consider the Central Authority for its official certificate, or confirm the solicitor route will satisfy the English court |
| Witness you need evidence from | Hague Evidence Convention letter of request, not service |
A tip for defense counsel
If your client was served in England or Wales, check how it was done. Was the process server instructed by a solicitor? Were the documents in a language your client understands? Was the request form properly completed and signed? A defect in any of these can support a motion to quash service.
