Founding Attorney
Enforcement of foreign arbitral awards is where an international arbitration either pays off or falls short. Winning an award is only a piece of paper until a court somewhere converts it into money or compliance. The instrument that makes this possible in most of the world is the Convention on the Recognition and Enforcement of Foreign Arbitral Awards of 1958 — the New York Convention. As of 2026, the Convention is in force in 172 contracting states. This guide explains, in practical terms, how enforcement of foreign arbitral awards works. It also covers the limited defenses a losing party can raise, and it shows where enforcement efforts most often stall.
What the New York Convention Does
The Convention obligates the courts of each contracting state to recognize arbitration agreements and to enforce arbitral awards made in other contracting states. Only a short list of narrow defenses applies. Its genius is what it forbids: a court asked to enforce a foreign award may not retry the merits of the dispute. The losing party does not get a second bite at the case — only the chance to establish one of the enumerated grounds for refusal.
Many states, including the United States, adopted two permitted reservations. First, reciprocity: the Convention applies only to awards made in other contracting states. Second, the commercial reservation: it applies only to disputes considered commercial under national law. Therefore, checking the enforcement state’s reservations is step one in any enforcement plan.
Enforcement of Foreign Arbitral Awards in U.S. Courts
The United States implemented the Convention in Chapter 2 of the Federal Arbitration Act, 9 U.S.C. §§ 201–208. The award creditor petitions a federal district court to confirm the award. Under § 207, the creditor must file the petition within three years after the award is made. Confirmation is designed to be a summary proceeding, not a new lawsuit. Once confirmed, the award becomes a U.S. judgment. As a result, the creditor can use the same mechanisms as for any other judgment: liens, garnishment, execution against assets, and post-judgment discovery.
The Seven Grounds for Refusing Enforcement
Article V of the Convention contains the only defenses. Five must be proven by the party resisting enforcement:
- Incapacity of a party, or invalidity of the arbitration agreement under its applicable law;
- Lack of proper notice of the arbitration, or another inability to present one’s case;
- The award decides matters beyond the scope of the submission to arbitration;
- The tribunal’s composition or the procedure did not accord with the parties’ agreement or the law of the seat;
- The award is not yet binding, or has been set aside or suspended by a competent authority at the seat.
The court may raise two further grounds itself. First, the subject matter may not be arbitrable under the enforcement state’s law. Second, enforcement would violate that state’s public policy. U.S. courts construe the public-policy defense narrowly. In practice, they reserve it for violations of the most basic notions of morality and justice — not mere disagreement with the tribunal’s reasoning. In practice, the large majority of contested enforcement proceedings end with the award enforced.
Where Enforcement of Foreign Arbitral Awards Gets Difficult
Finding assets in the right jurisdiction
A court can only reach assets within its jurisdiction. Serious enforcement of foreign arbitral awards therefore begins with asset mapping — identifying bank accounts, receivables, shareholdings, vessels, or commercial property in states with reliable courts. Ideally, this work starts before the arbitration is even filed.
Award debtors that are states or state entities
When the award debtor is a sovereign or a state-owned entity, enforcement runs through the Foreign Sovereign Immunities Act in the United States. The FSIA’s arbitration exception lifts immunity for actions to confirm awards governed by the Convention. Moreover, in CC/Devas v. Antrix (2025), the U.S. Supreme Court unanimously held that the statute imposes no separate minimum-contacts requirement for personal jurisdiction. Immunity from execution against specific sovereign assets remains a distinct hurdle, which we address in our companion explainer on foreign sovereign immunity.
Set-aside proceedings at the seat
An award annulled at the seat may still be enforceable elsewhere in limited circumstances. However, a pending set-aside application often prompts enforcement courts to adjourn. Coordinating the defense of the award at the seat with offensive enforcement elsewhere is a strategic decision, not an administrative one.
Practical Sequence for Award Creditors
A disciplined enforcement of foreign arbitral awards campaign follows a clear sequence. First, confirm the award within the limitation period in each target jurisdiction. Next, map assets and rank jurisdictions by attachment prospects. Then, consider interim attachments where available. Finally, anticipate the Article V defenses the debtor will raise. Costs and timelines vary widely with the debtor’s resistance — from a few months for an uncontested confirmation to years for a contested sovereign enforcement.
