Cross-Border Litigation: Resolving International Disputes in U.S. Courts

Cross-border disputes arise from international commercial relationships, corporate transactions, investments, financing arrangements, technology agreements, and other business activity involving more than one legal system.

Matters can include international contract and distribution disputes; M&A, post-closing, joint venture, and shareholder litigation; fraud and business tort claims; trade secret and intellectual property disputes; financial and securities disputes; and proceedings concerning recognition or enforcement of foreign judgments.

Many of the substantive claims resemble those found in complex commercial litigation. The cross-border dimension changes the procedural analysis. The parties may disagree not only about liability, but also about which court can decide the dispute, which country's law applies, where evidence can be obtained, and where a judgment can ultimately be collected.

A cross-border litigation strategy often begins with the forum rather than the merits. U.S. .roceedings may require separate analysis of subject-matter jurisdiction, personal jurisdiction, venue, contractual forum-selection provisions, and forum non conveniens.

These concepts answer different questions. A contract selecting New York law does not necessarily require litigation in a New York court. A forum-selection clause may identify a court without deciding every choice-of-law issue. And a foreign company's commercial relationship with the United States does not by itself resolve whether a particular court has personal jurisdiction over that company.

Foreign law can also become part of the U.S. .roceeding. Under Federal Rule of Civil Procedure 44.1, a party intending to raise an issue concerning foreign law must give notice by a pleading or other writing. The court may consider relevant materials or sources, including testimony, and treats its determination of foreign law as a ruling on a question of law. The Federal Rules of Civil Procedure therefore make foreign-law analysis a procedural issue as well as a substantive one.

Service abroad depends in part on whom the plaintiff is serving. Rule 4(f) governs service of an individual at a place outside any U.S. .udicial district. Rule 4(h)(2) governs service of a corporation, partnership, or association abroad and permits service in any manner prescribed by Rule 4(f), except personal delivery under Rule 4(f)(2)(C)(i).

The available method then depends on the destination country, any applicable treaty, and foreign law. Where the Hague Service Convention applies, service may proceed through the Convention's designated mechanisms, including a central authority where appropriate. Other treaty procedures may apply in different countries, while letters rogatory can remain relevant when no applicable treaty provides a suitable mechanism or when judicial assistance is otherwise required. The U.S. Department of State guidance on service abroad explains that accepted methods vary by country and that service choices can also affect later enforcement abroad.

For a foreign corporate defendant, service should therefore be planned together with jurisdiction and enforcement rather than treated as a clerical step after filing.

Evidence may be located with foreign affiliates, employees, banks, counterparties, cloud providers, or third parties. U.S. .itigation counsel must identify who controls relevant information, where it is stored, which witnesses are abroad, and whether foreign law or treaty procedures affect collection or transfer.

Letters rogatory may be used where treaty or other streamlined mechanisms are unavailable or unsuitable. The Department of State describes them as requests from one country's court to another country's court for judicial assistance and recommends checking applicable evidence treaties before using that process.

Preservation should not wait until every international discovery question is resolved. Relevant communications, contracts, financial records, board materials, messaging data, and device information may be subject to different retention systems in different countries. The collection protocol should account for both U.S. .itigation needs and applicable restrictions in the jurisdiction where the information is located.

The same transaction can produce litigation, arbitration, regulatory proceedings, or investigations in multiple jurisdictions. The proceedings may concern overlapping evidence while applying different procedural rules, schedules, remedies, and disclosure obligations.

The strategy should identify whether a ruling or factual position in one forum can affect another. Depending on the courts and circumstances, relevant mechanisms may include stays, forum non conveniens, anti-suit relief, comity, and other forum-specific procedural measures. None should be assumed to apply simply because related litigation exists elsewhere.

Coordination is equally important outside motion practice. Witness testimony, expert positions, document productions, privilege decisions, and settlement terms developed in one country may have consequences in another. A cross-border litigation strategy should therefore maintain consistent factual positions while accounting for the legal requirements of each proceeding.

Some international disputes belong in court; others are subject to an arbitration agreement. The first question is often what the parties' contract requires rather than which process appears more attractive after the dispute arises.

Relevant considerations can include the scope and enforceability of the dispute-resolution clause, available interim relief, discovery needs, confidentiality, the counterparty, and the jurisdictions where assets are located. When an arbitration agreement governs, related issues may fall within international arbitration rather than the court-litigation strategy addressed here.

Litigation and arbitration can also coexist. Court proceedings may concern jurisdictional questions, provisional relief, or enforcement while the underlying merits proceed in arbitration.

A foreign company facing U.S. .itigation can encounter procedural requirements that differ substantially from those in its home jurisdiction. Early decisions may involve personal jurisdiction, removal or federal jurisdiction, service, document preservation, U.S. .iscovery, depositions, expert practice, and potential jury proceedings.

A company served overseas should first determine what court issued the summons, when a response is due, how service was attempted, and whether threshold jurisdictional or forum objections need to be preserved. Beginning merits litigation before evaluating those issues can narrow strategic options.

Foreign companies also need coordinated communication between U.S. .itigation counsel and existing home-country counsel. U.S. .leadings, witness preparation, discovery positions, and settlement communications should be evaluated against related proceedings and legal obligations abroad.

A favorable judgment has limited commercial value if it cannot be recognized or collected where the counterparty's assets are located. Asset location and likely enforcement jurisdictions should therefore inform forum and remedy decisions early in the dispute.

Recognition of foreign-country money judgments in the United States generally depends on the law of the state where recognition is sought rather than one nationwide federal recognition rule. The Uniform Law Commission's Foreign-Country Money Judgments Recognition Act provides a model framework used by states, while state enactments and common-law rules can differ.

Counsel may need to examine whether the foreign judgment is final and enforceable, whether the rendering court had an adequate jurisdictional basis, and whether a statutory or common-law ground for nonrecognition applies. Enforcement planning should be kept distinct from international arbitral-award enforcement, which follows a different legal framework.

Choosing a forum without evaluating enforcement. A legally available forum may not be commercially useful if the counterparty's assets are elsewhere and recognition will be difficult.

Treating governing law and forum selection as the same issue. A contract can address one without resolving the other.

Serving a foreign company as though it were a domestic defendant. Rule 4(h)(2), Rule 4(f), applicable treaties, and foreign law can affect the permitted method.

Waiting to identify overseas evidence. Witness availability, retention systems, foreign-law restrictions, and treaty procedures can make later collection slower or more difficult.

Assuming parallel cases will automatically be halted. The available procedural response depends on the particular courts and proceedings.

Assuming § 1782 is available for every international arbitration. ZF Automotive requires attention to the nature of the adjudicative body.

Cross-border litigation counsel can address threshold jurisdiction and forum issues, pleadings and motions, service abroad, foreign-law questions under Rule 44.1, and cross-border discovery. Representation may also extend to § 1782 proceedings, provisional relief, settlement, and trial.

For foreign companies and overseas law firms, U.S. .ounsel can coordinate the American proceeding with local counsel so that litigation positions remain consistent with related proceedings and obligations elsewhere.
