1. Why International Disputes Are Different from Domestic Commercial Litigation
Every international dispute involves a threshold question that domestic litigation does not: which country's courts have jurisdiction, which country's law governs, and where any judgment or award can actually be enforced.
Forum selection clauses in international contracts are the primary tool for resolving these questions in advance. A well-drafted forum selection clause designates a specific court or arbitral institution, specifies the seat of any arbitration, and selects the governing law for both substantive and procedural purposes. Courts in the United States and most major commercial jurisdictions enforce mandatory forum selection clauses unless the opposing party can demonstrate that enforcement would be unreasonable or unjust, a standard that is difficult to meet.
Choice of law clauses operate independently of forum selection clauses. The parties may choose to litigate in the courts of one country while agreeing that the substantive law of another country governs the contract. This combination is common in contracts between parties from different common law and civil law jurisdictions, where familiarity with specific legal frameworks matters more than proximity to the dispute. The interaction between the chosen forum's procedural rules and the chosen substantive law requires careful analysis at the drafting stage, because procedural rules governing discovery, evidence, and injunctions vary significantly across jurisdictions and can affect outcomes as much as the substantive law.
How the Cisg Applies to International Sales Contracts and When to Exclude It
The United Nations Convention on Contracts for the International Sale of Goods applies automatically to contracts for the sale of goods between parties whose places of business are in different CISG signatory states, and it displaces domestic contract law on the issues it covers unless the parties opt out.
The CISG covers contract formation, the rights and obligations of buyers and sellers, remedies for breach, and risk of loss. It does not cover the validity of the contract, the transfer of title, or product liability claims. The CISG's approach to several fundamental contract law issues differs from U.S. .omestic law under the Uniform Commercial Code, including the mirror image rule for offer and acceptance, the perfect tender rule, and the treatment of oral contracts without a writing requirement.
Parties who prefer the predictability of a familiar domestic legal regime can exclude the CISG by express language in the contract stating that the convention does not apply and designating specific domestic law in its place. Contracts that do not include an express CISG exclusion are subject to the convention regardless of what domestic law the choice of law clause designates. An attorney who handles international contracts can review the contract's choice of law clause and determine whether the CISG applies, whether exclusion is advisable, and what consequences flow from the difference between CISG and domestic law on the specific issues most likely to arise in that business relationship.

| Mediation | UNCITRAL, ICC mediation rules | Preserves relationship, faster resolution | No binding result without agreement |
2. How International Disputes Are Resolved through Arbitration
International arbitration has become the preferred method of resolving international commercial disputes for one reason above all others: an arbitral award issued in one country can be enforced in courts of over 170 countries under the New York Convention, while a court judgment issued in one country can only be enforced in another country if a specific enforcement treaty or reciprocal recognition relationship exists.
The major international arbitral institutions each maintain their own procedural rules, fee schedules, and administrative frameworks. The International Chamber of Commerce in Paris administers the most widely used commercial arbitration rules globally, and ICC arbitration clauses appear in contracts involving parties from every major commercial jurisdiction. The International Centre for Settlement of Investment Disputes in Washington handles disputes between foreign investors and host governments under bilateral investment treaties. UNCITRAL arbitration rules are used in ad hoc proceedings and under investment treaties where no institutional home has been specified.
Seat selection is among the most consequential decisions in drafting an international arbitration clause. The seat of the arbitration determines which national courts have supervisory jurisdiction over the proceedings, which procedural law governs the conduct of the arbitration, and in what courts the award will initially be challenged if a party seeks to set it aside. Seats in countries with supportive arbitration legislation and courts that rarely interfere with arbitral proceedings are strongly preferred for commercial arbitrations.
How to Enforce an International Arbitration Award in the United States and Abroad
Enforcement of an international arbitration award under the New York Convention requires the winning party to file a petition to confirm the award in a court of competent jurisdiction in the country where enforcement is sought.
In the United States, enforcement of foreign arbitral awards is governed by Chapter 2 of the Federal Arbitration Act, which implements the New York Convention. A party seeking to enforce a foreign award files a petition in federal district court, attaches the original award and the arbitration agreement, and the court confirms the award unless the opposing party can establish one of the narrow grounds for refusal specified in Article V of the New York Convention. Grounds for refusal include incapacity of the parties, procedural irregularities in the arbitral proceedings, an award beyond the scope of the submission, violation of public policy, and non-arbitrability of the subject matter under the law of the enforcement country.
Public policy is the ground most frequently invoked to resist enforcement in the United States, and U.S. .ourts have consistently interpreted it narrowly to cover only violations of the most basic notions of morality and justice rather than any conflict with domestic law. An award that would not have been available under U.S. .aw is not thereby unenforceable in U.S. .ourts. An attorney who handles international arbitration proceedings can petition for confirmation and respond to enforcement resistance arguments in the specific jurisdiction where the award debtor's assets are located.
3. When International Disputes Involve Foreign Governments or State Entities
Disputes with foreign governments, state-owned enterprises, and sovereign wealth funds present a layer of legal complexity that commercial disputes between private parties do not, because the doctrine of sovereign immunity limits the circumstances under which a foreign government can be sued in U.S. .ourts.
The Foreign Sovereign Immunities Act, codified at 28 U.S.C. § 1602 et seq., is the exclusive basis for jurisdiction in U.S. .ourts over foreign states and their agencies and instrumentalities. The FSIA provides that foreign states are presumptively immune from suit in U.S. .ourts subject to specific statutory exceptions. The most important commercial exception strips immunity when the claim arises from a commercial activity carried on in the United States or performed in connection with a commercial activity that causes a direct effect in the United States.
Whether a specific activity constitutes commercial activity for FSIA purposes depends on the nature of the act rather than its purpose. A foreign government that issues bonds in the U.S. .arket, enters into a construction contract with a U.S. .ompany, or operates a commercial airline is engaged in commercial activity regardless of the governmental purpose those activities serve. The FSIA's waiver exception also permits suits against foreign states that have expressly or implicitly waived their immunity, which commercial arbitration clauses in contracts with foreign state entities are generally interpreted to do.
How Investor-State Arbitration Works under Bilateral Investment Treaties
Bilateral investment treaties give foreign investors a direct right to bring arbitration claims against host governments for treaty breaches including expropriation, denial of fair and equitable treatment, and failure to provide full protection and security, without requiring the investor to exhaust local remedies in the host country's courts.
The United States has bilateral investment treaties with over 40 countries and investment chapters in free trade agreements with dozens more. When a U.S. .nvestor's investment in a foreign country is expropriated, subjected to discriminatory treatment, or denied the protections the treaty guarantees, the investor can file an arbitration claim directly against the host government under the treaty's dispute resolution provisions. Most U.S. BITs provide for ICSID arbitration or UNCITRAL arbitration at the investor's election.
Investor-state arbitration awards are enforced under the ICSID Convention directly through the court systems of ICSID member states without the need for a separate enforcement proceeding in most jurisdictions. This direct enforcement mechanism is one of the most powerful features of ICSID arbitration and distinguishes it from commercial arbitration enforced under the New York Convention. An attorney who handles investment dispute claims can evaluate whether a specific investment qualifies for treaty protection, which treaty applies, and whether the host government's conduct meets the threshold for a treaty breach claim.
How to Obtain Evidence Located in a Foreign Country for U.S. Proceedings
Evidence located outside the United States cannot be obtained through standard U.S. .iscovery procedures, and the mechanisms available to collect it depend on whether the foreign country is a party to applicable international evidence conventions.
The Hague Evidence Convention, to which more than 60 countries are parties, provides a framework for obtaining evidence from foreign countries through letters rogatory transmitted through central authorities. A U.S. .arty that needs documentary evidence or witness testimony from a signatory country can use the Convention's procedures, though the process is slower than domestic discovery and the foreign country retains the right to refuse execution on grounds that compliance would violate its domestic law or public policy.
For discovery from foreign parties in U.S. .itigation, 28 U.S.C. § 1782 allows U.S. .istrict courts to order discovery from persons found in the United States for use in proceedings before a foreign or international tribunal. The Supreme Court's decision in ZF Automotive US, Inc. .. Luxshare, Ltd., 596 U.S. 619 (2022), limited § 1782 assistance to proceedings before governmental bodies, excluding private arbitral tribunals, which significantly narrowed its availability in international commercial arbitration. An attorney who handles international litigation can identify the applicable evidence collection mechanism and navigate the procedural requirements in each country where relevant evidence is located.
Foreign judgments obtained against U.S. .efendants in courts abroad are not automatically enforceable in the United States. The United States has no multilateral treaty governing the recognition of foreign court judgments, and enforcement depends on the law of the specific U.S. .tate where recognition is sought. Most states apply either the Uniform Foreign-Country Money Judgments Recognition Act or common law recognition principles that require the foreign court to have had jurisdiction and provided due process, but neither standard is identical across states and the analysis must be performed jurisdiction by jurisdiction.
4. Frequently Asked Questions about International Disputes
Business executives, in-house counsel, and individuals with cross-border claims bring a distinctive combination of procedural and substantive questions to an international dispute consultation that rarely arise in domestic litigation. The questions that surface most consistently across those engagements are addressed here.
What Is an International Dispute and What Makes It Different from a Domestic Lawsuit?
An international dispute is a legal conflict between parties located in different countries, or involving assets, contracts, or conduct that crosses national borders. It differs from a domestic lawsuit in that it involves threshold questions of jurisdiction, applicable law, and enforceability that domestic litigation does not present. A judgment or award issued in one country cannot automatically be enforced in another, and the mechanism for cross-border enforcement depends on whether a treaty relationship exists, what forum the parties chose in their contract, and where the defendant's assets are located.
What Is the New York Convention and Why Does It Matter for International Arbitration?
The New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards is an international treaty in force in over 170 countries that requires signatory states to recognize and enforce arbitral awards issued in other signatory states subject to narrow exceptions. It is the primary reason international arbitration is preferred over foreign court litigation for commercial disputes, because an arbitral award confirmed in one country can be enforced against assets in any of the over 170 signatory countries, while a court judgment issued in one country can only be enforced in another country if a specific bilateral or multilateral enforcement treaty exists.
Does the Cisg Apply to My International Sales Contract?
The CISG applies automatically to contracts for the sale of goods between parties whose places of business are in different CISG signatory states unless the contract expressly excludes it. The United States is a signatory. If your counterparty's place of business is in another signatory state and your contract does not expressly state that the CISG does not apply, the convention governs the contract formation and performance issues it covers. CISG exclusion clauses are simple to draft and should be evaluated for any new international sales contract because the CISG's rules differ from U.S. .omestic contract law in several important respects.
Can a Foreign Government Be Sued in U.S. Courts?
Yes, under the specific exceptions to sovereign immunity provided by the Foreign Sovereign Immunities Act. The most important commercial exception allows U.S. .ourts to exercise jurisdiction over claims arising from commercial activity conducted in the United States or with direct effects in the United States. A foreign government that issued bonds in U.S. .arkets, entered a commercial contract with a U.S. .arty, or operated a commercial business in the United States has waived sovereign immunity for claims arising from those activities. The FSIA analysis requires careful examination of the specific nature of the activity giving rise to the claim.
What Is Investor-State Arbitration and Who Can Use It?
Investor-state arbitration is a dispute resolution mechanism provided by bilateral investment treaties and investment chapters of free trade agreements that allows foreign investors to bring arbitration claims directly against the host government for breaches of treaty protections. Qualifying investors must hold a covered investment in the host country and must be nationals of a country that has a bilateral investment treaty or free trade agreement with the host country containing investor protection provisions. Claims can cover expropriation, discriminatory treatment, and denial of fair and equitable treatment without requiring the investor to first pursue remedies in the host country's domestic courts.
How Is a Foreign Arbitration Award Enforced against Assets in the United States?
Enforcement of a foreign arbitral award in the United States proceeds through a petition to confirm the award filed in a federal district court under Chapter 2 of the Federal Arbitration Act, which implements the New York Convention. The court confirms the award unless the respondent establishes one of the narrow grounds for refusal under Article V of the New York Convention, including incapacity of the parties, procedural irregularities, an award beyond the scope of the submission, or violation of U.S. .ublic policy. U.S. .ourts interpret public policy narrowly and rarely refuse enforcement on that ground. An attorney who handles international dispute resolution cases can manage the confirmation proceeding and respond to any enforcement resistance in the specific district where the respondent's U.S. assets are located.
