Discovery From a Foreign Party in a United States Case
A foreign company that litigates here is subject to the same discovery rules as anyone else, including for records kept overseas. Where producing them would breach the law of the country holding them, the court balances the two demands rather than deferring to either.
The rule in short
The Supreme Court held in Aérospatiale that the Evidence Convention does not displace the Federal Rules for discovery sought from a party subject to the court's jurisdiction, and that no first-resort requirement applies. Where compliance would violate foreign law, courts apply a comity analysis weighing the importance and specificity of the request, where the material originated, the availability of alternatives, and the competing national interests.
A foreign company that sues or is sued here is a litigant like any other, and the discovery rules apply to it in full. The difficulty arises when the material sought is held in a country whose law forbids sending it out. Two legal systems then make incompatible demands of the same party, and the court has to decide which one gives way.
When the ordinary rules apply
The Supreme Court settled the framework in Aérospatiale. The Evidence Convention does not deprive a court of the power to order a party subject to its jurisdiction to produce evidence located abroad, and there is no rule requiring the Convention to be tried first. Whether to use the treaty route is a case-by-case judgment about the particular facts, the sovereign interests involved, and the likelihood that the treaty would prove effective.
The treaty route remains genuinely useful where the holder of the evidence is a stranger to the case, because a court has no power over a non-party abroad at all. That route is described in taking evidence abroad through letters of request. For a party already before the court, the ordinary rules are the starting point.
Control, and how far it reaches
Rule 34 requires production of material in a party's possession, custody or control. Control is the operative word where corporate groups are involved, and courts have not settled on a single test. Some ask whether the party has the legal right to obtain the documents on demand. Others ask whether it has the practical ability to get them, looking at how the group actually operates.
The difference decides many cases. Under a legal right test, a subsidiary sued here may owe nothing for its parent's files. Under a practical ability test, a demonstrated history of the parent supplying documents on request can establish control. Where control fails, the requesting party is left with a letter of request or a section 1782 application aimed at the entity that holds the material.
The comity analysis
Where production would violate the law of the country holding the material, courts apply a multi-factor comity analysis. The recurring factors are the importance of the documents to the litigation, the degree of specificity of the request, whether the information originated in the United States, the availability of alternative means of obtaining it, and the extent to which non-compliance would undermine interests here or compliance would undermine interests there.
Most courts add two more: the hardship the producing party would face, and its good faith. A narrowly drawn request for material central to the case, unavailable anywhere else, generally survives the analysis. A broad category request for material of marginal importance generally does not, which is a reason to narrow before the motion rather than after it.
Parties often file the text of a foreign prohibition and treat the matter as closed. Courts ask further questions: whether the statute is enforced in practice, whether prosecutions have followed disclosures in foreign litigation, whether an exemption or consent procedure exists, and whether the party applied for one. A statute that has never been enforced against a litigant carries much less weight than one that has, and the party asserting it carries the burden of establishing what it actually does.
| Holder of the material | Compulsion available | Governing framework | Usual obstacle |
|---|---|---|---|
| Party to the case, records abroad | Yes, against the party | Federal Rules, with a comity analysis | Foreign prohibition on disclosure |
| Foreign affiliate of a party | Only if the party controls the material | Rule 34 control test | Which control test the court applies |
| Non-party abroad | No direct compulsion | Letter of request under the Evidence Convention | Time, and the state's declarations |
| Non-party found in the district | Yes, by subpoena | Rule 45; section 1782 for foreign cases | Territorial limits and undue burden |
| Foreign state or instrumentality | Limited, and only if immunity is lost | The sovereign immunity statute | Immunity from jurisdiction in the first place |
What happens when a party will not produce
Rule 37 supplies a ladder: an order compelling production, then cost-shifting, then evidentiary consequences such as taking facts as established or precluding a defense, then in the extreme case default or dismissal. Courts reach the top of the ladder rarely where the obstacle is genuinely foreign law.
The governing principle comes from Société Internationale: a party's failure to comply is treated differently where the inability arises from circumstances beyond its control and not from its own conduct. Good faith efforts to secure permission from the foreign authority matter at this stage. They do not excuse the obligation, but they shape which rung of the ladder the court chooses.
Sequencing the problem
The workable order is to narrow the request first, then establish control, then run the comity analysis on what remains. A protective order restricting the use and further disclosure of produced material often resolves a foreign privacy objection entirely, since the foreign interest is frequently in confidentiality rather than in secrecy from the court.
Where the material is genuinely unreachable, the consequence may be argued as a reason the case belongs elsewhere, which connects to forum objections and parallel proceedings abroad. Objections resting on the sensitivity of the material itself are handled through privileges, their scope and how they are waived, and disputes about whether marginal material is worth the fight through relevance and the balancing that keeps it out.
Points to carry away
- A party before the court may be ordered to produce material it controls abroad.
- The Evidence Convention is optional, not a required first step, for party discovery.
- Courts weigh comity factors rather than deferring automatically to foreign law.
- A foreign blocking statute is considered but does not by itself excuse production.
- Good faith efforts to obtain foreign permission affect the sanction, not the obligation.
- Dismissal is inappropriate where non-compliance is not the party's own fault.
Questions readers ask
Does it matter where the documents are physically stored?
Less than parties expect. The obligation attaches to the litigant, not to the file cabinet, so a party that controls material can be ordered to produce it regardless of the country it sits in. Location matters at the second stage, where it feeds the comity analysis: material that originated abroad and never left has a stronger claim to the protection of local law than material generated here and shipped out. Storing data offshore in anticipation of litigation tends to be treated as an aggravating fact.
What is the effect of a data protection regime rather than a blocking statute?
Courts treat it as the same kind of problem with a different label. A regime that restricts transferring personal data abroad creates a genuine legal constraint on the producing party, and courts weigh it in the comity analysis alongside the mechanisms the regime itself supplies, such as consent, redaction, or a recognized ground for transfer in litigation. What generally does not work is asserting the regime as a blanket bar without showing that its own exceptions were explored.
Can a party avoid the problem by asking the foreign authority for permission?
It should try, and the attempt has real value even when it fails. Courts distinguish between a party that made a documented application to the relevant ministry or regulator and one that asserted foreign law from the outset. A refusal on the record strengthens the argument for a narrower order or a lesser sanction. A party that never asked is treated as having chosen the foreign prohibition, and finds the comity balance tilting sharply against it.

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.
