Serving Where the Convention Does Not Apply
Not every foreign defendant is reachable through the Service Convention. The treaty falls away when the destination is not a party, when the address is unknown, and whenever the forum's own law lets service be completed at home.
The rule in short
Where the Service Convention does not govern, three routes remain. Service may be completed domestically on an agent, which takes the case out of the treaty entirely. A letter rogatory may be sent through diplomatic channels to a foreign court, which is reliable and slow. Or the court may order an alternative means under Federal Rule of Civil Procedure 4(f)(3), provided it is not prohibited by international agreement and satisfies due process.
The Service Convention covers a large share of foreign defendants and not all of them. It has no application where the destination country is not a party, where the address of the person to be served is unknown, or where the forum's own law allows service to be completed without sending anything abroad. Each of those gaps has its own route.
When the treaty falls away
Three situations account for most of them. The destination country may simply not be a party, in which case the status table settles the question in a minute. The address may be unknown, which Article 1 excludes expressly, though a party cannot manufacture the exclusion by declining to look. Or the forum's law may permit valid service on someone present locally.
That last point is the important one, and it is easy to state backward. The Convention is triggered by the forum's own law calling for transmission abroad. Where the forum's law says service on a domestic recipient completes service on the foreign defendant, there is no occasion to transmit, and the treaty never enters the case. The mechanics where it does apply are set out in serving process abroad under the Service Convention.
Serving through a domestic agent
Several kinds of agent will do. A registered agent designated by a foreign entity qualified to do business locally. An agent appointed by contract, which is common in cross-border commercial agreements and is worth negotiating for that reason alone. A state official designated by a long-arm statute as the recipient for substituted service. And in some states, a domestic entity treated as an involuntary agent for a foreign affiliate.
Waiver is also available. A defendant abroad may return a waiver of service, which avoids the whole exercise, although the rule's cost-shifting penalty for refusing does not apply to a defendant outside any judicial district of the United States. Waiver is worth requesting anyway, since a cooperative foreign defendant often prefers it to a consular visit.
Letters rogatory
A letter rogatory is a formal request from the court where the case is pending to a court in the foreign country, asking it to perform an act, including effecting service. It travels through diplomatic channels: from the issuing court to the executive, to the foreign ministry, to the local court, and back again. Section 1781 authorizes the transmission and also permits direct transmittal in defined circumstances.
The route is reliable in the sense that the resulting proof of service is beyond argument, and it is slow. A year is not unusual. Where the destination is a country with which no treaty relationship exists and the defendant's cooperation cannot be expected, it may be the only route that produces a judgment enforceable in that country later.
Parties sometimes treat a successful motion under Rule 4(f)(3) as the end of the problem. It is not. Service and personal jurisdiction are separate requirements, and a defendant served by email in a country with which the forum has no contacts will simply move to dismiss on jurisdictional grounds. The order solves delivery. Whether the court may hear the case at all is a different question with a different answer.
| Route | Source of authority | Best used when | Typical time |
|---|---|---|---|
| Domestic agent or waiver | Forum law; Rule 4(d) | The defendant has a local agent or will cooperate | Days to weeks |
| Foreign country's own method | Rule 4(f)(2)(A) | The local law permits a private process server | Weeks to months |
| Letter rogatory | Rule 4(f)(2)(B); 28 U.S.C. 1781 | No treaty relationship and enforcement will be sought there | Many months to a year |
| Clerk-dispatched mail with receipt | Rule 4(f)(2)(C)(ii) | Local law does not prohibit it and the address is solid | Weeks |
| Court-directed means | Rule 4(f)(3) | Ordinary routes are unavailable or futile | Days after the order |
Court-directed means under the rule
Rule 4(f)(3) permits service by other means not prohibited by international agreement, as the court orders. Two conditions govern. The method must not be prohibited by an applicable international agreement, so a method a treaty party has objected to remains unavailable. And it must comport with due process, meaning it is reasonably calculated under the circumstances to apprise the defendant of the action and give an opportunity to respond.
Motions are usually supported by evidence that the defendant uses the proposed channel: recent emails from the address, an active account, or correspondence through counsel. Courts also weigh whether the defendant appears to be evading, which shifts the balance toward permitting an unconventional method.
Foreign states follow a separate rule
None of the above applies to a foreign state. Service on a foreign state, its political subdivisions, agencies and instrumentalities is governed by 28 U.S.C. 1608, which sets out a mandatory hierarchy: a special arrangement, then an applicable international convention, then a clerk-dispatched mailing, then diplomatic channels. The steps must be attempted in order, and courts have treated the requirement strictly for the state itself.
Getting service right is the foundation for everything after it, including personal jurisdiction over a foreign defendant and the immunity analysis in suing a foreign state. The same diplomatic channel used for letters rogatory also carries requests for evidence, described in taking evidence abroad through letters of request.
Points to carry away
- The Convention does not apply where the address of the person to be served is unknown.
- Valid domestic service on an agent means nothing is transmitted abroad at all.
- A letter rogatory is transmitted through diplomatic channels and is measured in months.
- Rule 4(f)(3) permits any court-ordered means not prohibited by international agreement.
- Alternative means must still be reasonably calculated to give actual notice.
- Service on a foreign state follows its own mandatory statutory sequence.
Questions readers ask
Must a party try the ordinary methods before asking for a court order?
The rule imposes no hierarchy, and courts have said so. In practice most judges want to see that the ordinary routes were considered and why they will not work: the country is not a treaty party, the address is unverified, prior attempts failed, or the defendant is evading. A motion that simply asks for email service because it is faster tends to be denied. A motion that documents two failed attempts and shows the proposed address is actively used tends to be granted.
Is service by email or messaging app allowed?
It can be, under a court order, where nothing in an applicable international agreement prohibits it and the method is reasonably calculated to reach the defendant. Courts have permitted service by email, by messaging platforms, on a website's contact form, and on the defendant's counsel. The showing that matters is that the specific address or account is current and used by the defendant, usually proved by recent correspondence. A dormant address will not support the order.
Does serving a subsidiary reach the foreign parent?
Only where the forum's own law makes the subsidiary a proper recipient for the parent, which is a substantive question and not a shortcut. Some states treat a domestic entity as an involuntary agent for a foreign affiliate in defined circumstances, and where that law is satisfied the service is complete at home and no treaty is engaged. Where it is not satisfied, serving the subsidiary accomplishes nothing against the parent and can waste the limitation period.

Suing a Foreign State: Immunity as the Default
The Foreign Sovereign Immunities Act makes a foreign state immune from the jurisdiction of federal and state courts except as the statute itself provides, and it is the sole basis for obtaining jurisdiction over a foreign state. A foreign state includes its political subdivisions and its agencies and instrumentalities. Exceptions cover waiver, commercial activity, certain expropriations, property in the United States, some domestic torts, and arbitration.
Forum Objections and Parallel Proceedings Abroad
Forum non conveniens permits a court with jurisdiction to dismiss where an adequate alternative forum exists and the balance of private and public interest factors strongly favors trial there. An alternative forum is adequate where the defendant is amenable to process and the remedy is not so unsatisfactory as to be no remedy at all. A foreign plaintiff's choice of forum receives less deference than a domestic plaintiff's.
The Commercial Activity Exception
A foreign state loses immunity where the action is based upon commercial activity carried on in the United States, upon an act performed here in connection with commercial activity elsewhere, or upon an act outside the United States in connection with commercial activity elsewhere that causes a direct effect here. Commercial character is determined by the nature of the conduct rather than its purpose, following the market-player test in Weltover.
