Cross-Border Disputes: Recognition and Enforcement of Judgments and Awards

Concept: two projects, not one

A cross-border dispute is really two projects that people treat as one. The first is the merits — establishing, in some court or tribunal, that the other side owes the money or must do the thing. The second is execution — converting that decision into control over assets that happen to sit in a different legal system from the one that decided. Winning the first proves nothing about the second. A creditor can hold a final English judgment and recover nothing because the debtor's only assets are shares and a villa in a country that will not enforce an English judgment; another creditor with a weaker case but a London-seated arbitration award can be paid in full, because that award travels almost everywhere.

The reason the two projects diverge is that the world has one near-universal treaty for arbitral awards and a patchwork for court judgments. The New York Convention of 1958 binds 172 states to recognise and enforce foreign arbitral awards, refusing only on the narrow grounds in its Article V. Court judgments have no equivalent of that reach: enforcement depends on whether a treaty, a European regulation, or the requested country's own common-law or civil-code rules happen to connect the two jurisdictions in your case. This is why the single most consequential decision in a cross-border matter is often made years before any dispute — the choice, in the contract, between a court and an arbitration clause — one of the terms fought over when the deal documents are negotiated.

Take a concrete pair. A lender in England contracts with a borrower whose wealth is a Dubai trading company and real estate in onshore Dubai. If the loan agreement sends disputes to the English courts, the lender who wins in London must then find a route into the UAE: since a September 2022 UAE Ministry of Justice letter to the Dubai Courts, English money judgments can be enforced onshore on the basis of reciprocity, and the DIFC Courts also act as a conduit — but neither route is automatic, and both can be contested. If instead the agreement sends disputes to London arbitration, the resulting award is enforced in the UAE under the New York Convention, to which the UAE acceded on 21 August 2006, on the same narrow Article V grounds that apply everywhere else. Same debtor, same assets, same underlying claim — two very different last miles.

Three features of this field are worth holding onto before the mechanics:

• A forum clause guarantees a forum, not assets and not recognition. Choosing English court jurisdiction, or a London seat, tells you where the fight happens. It does not put assets within reach, and it does not bind a third country to honour the result. Recognition is a separate question decided by the country where you finally chase the money.
• Jurisdiction, governing law and enforcement are three different things. A court in one country can apply the law of a second country to a contract performed in a third, and the decision may then have to be enforced in a fourth. Each link is governed by its own rules; a clause that fixes one says nothing about the others.
• Interim protection is not the remedy. Freezing an asset before trial stops it moving; it does not transfer it, does not create security, and does not give the freezing party priority over other creditors. It buys time for the real remedy, which is execution after a decision, and it is no substitute for having taken security over assets when the money went out.

The sections below follow the life of a claim: what to settle before the dispute (jurisdiction, governing law, service, evidence), how to protect assets during it (interim relief), the fork between judgment and award, the recognition-and-enforcement routes that attach to each instrument, and the last mile — finding assets and testing whether the debtor is actually collectable.

Before the dispute: jurisdiction, governing law, service, evidence

Four things are settled at or near the start, and each is a distinct legal object.

Jurisdiction is which court may hear the case. Parties can agree it in advance through a choice-of-court clause, but the weight that clause carries depends on the instrument behind it. Inside the EU, Article 25 of Regulation (EU) No 1215/2012 (Brussels Ia) makes a chosen court's jurisdiction exclusive unless the agreement is null. Between the wider set of states that have joined the 2005 Hague Choice of Court Convention — 39 Contracting Parties as at September 2026, among them the EU, Denmark separately from 1 September 2018, the United Kingdom, Mexico, Singapore, Montenegro, Ukraine, Switzerland from 1 January 2025, Bahrain from 1 July 2025 and Monaco from 1 March 2026 — an exclusive choice-of-court agreement obliges the chosen court to hear the case and every other Contracting State to decline, and it makes the resulting judgment enforceable under Article 8 of that Convention. Outside those instruments, a foreign jurisdiction clause is persuasive but not always decisive: a court elsewhere may still take the case under its own rules.

Governing law is the law the court applies to the substance. It is chosen separately and does not follow the forum: an English court routinely applies foreign law to a contract, and a Rome I or Rome II analysis in the EU can point to the law of a country with no court involvement at all. Governing law shapes who wins; it does not decide where the judgment can be enforced.

Service is the formal delivery of proceedings on a defendant abroad, and it is where cross-border claims most often stumble on procedure. Between its parties, the Hague Service Convention of 1965 channels service through each state's Central Authority; within the EU the recast Service Regulation ((EU) 2020/1784) does the same electronically between Member States. Getting service wrong is not a technicality: defective service is an express ground to refuse recognition later — Article 45(1)(b) of Brussels Ia lets a court refuse a default judgment where the defendant "was not served with the document which instituted the proceedings … in sufficient time and in such a way as to enable him to arrange for his defence," and Article V(1)(b) of the New York Convention refuses an award where a party "was not given proper notice."

Evidence located abroad is obtained under its own regime — the Hague Evidence Convention of 1970 or, within the EU, the recast Evidence Regulation ((EU) 2020/1783) — not by simply demanding documents from a foreign party. How much pre-trial disclosure is available differs sharply between common-law and civil-law systems, and that difference is itself a reason parties prefer one forum over another.

Parallel proceedings and the race to the forum

Cross-border disputes rarely stay in one court. A debtor who dislikes the contractual forum sues first somewhere else — usually at home, usually for a declaration of non-liability — and the creditor then spends a year arguing about where the case belongs before anyone looks at the merits. Who wins that argument is decided by rules that differ sharply inside and outside the EU.

Inside the EU the rule is mechanical. Under Article 29 of Brussels Ia, where proceedings "involving the same cause of action and between the same parties are brought in the courts of different Member States, any court other than the court first seised shall of its own motion stay its proceedings until such time as the jurisdiction of the court first seised is established". Article 32(1) fixes the moment of seisin at the lodging of the claim, "provided that the claimant has not subsequently failed to take the steps he was required to take to have service effected on the defendant" — which is why filing order and correct service are one question and not two.

The 2012 recast then closed the loophole that made the first-seised rule abusable: by Article 31(2), where a court designated by an exclusive choice-of-court agreement is seised, "any court of another Member State shall stay the proceedings until such time as the court seised on the basis of the agreement declares that it has no jurisdiction under the agreement". The chosen court now goes first even if the other side filed earlier.

Outside that system the weapon is the anti-suit injunction — an order against the party, not against the foreign court, to discontinue proceedings brought in breach of a jurisdiction or arbitration clause. Between EU Member States it is prohibited: in Allianz SpA v West Tankers Inc (Court of Justice, Grand Chamber, 10 February 2009, Case C-185/07) the Court ruled that it is "incompatible with Council Regulation (EC) No 44/2001 … for a court of a Member State to make an order to restrain a person from commencing or continuing proceedings before the courts of another Member State on the ground that such proceedings would be contrary to an arbitration agreement". The prohibition binds courts, not tribunals: in Gazprom OAO v Lietuvos Respublika (Court of Justice, Grand Chamber, 13 May 2015, Case C-536/13) the Court held that the Regulation "does not govern the recognition and enforcement of arbitral awards issued by an arbitral tribunal in another Member State", so a Member State court may recognise and enforce an award that itself orders a party to drop claims.

One clause, two systems, one injunction. Since Brussels Ia ceased to apply to the United Kingdom, the West Tankers bar no longer restrains the English courts, and they have used the freedom. In UniCredit Bank GmbH v RusChemAlliance LLC (UK Supreme Court, 18 September 2024, [2024] UKSC 30) the bonds were governed by English law but sent disputes to ICC arbitration seated in Paris; the beneficiary sued in Russia instead. The Supreme Court unanimously upheld a final anti-suit injunction, holding that the parties' express choice of English law for the contract carried the arbitration agreement with it despite the foreign seat, and that England was the proper place to bring the claim because the French courts could not grant that relief. The holding is narrow and useful: it is the law of the arbitration agreement, not the seat, that decides who can police the clause.

For arbitral proceedings commenced on or after 1 August 2025 that default is reversed by statute, whenever the arbitration agreement was made. Section 1 of the Arbitration Act 2025 inserts a new section 6A into the Arbitration Act 1996: "The law applicable to an arbitration agreement is — (a) the law that the parties expressly agree applies to the arbitration agreement, or (b) where no such agreement is made, the law of the seat of the arbitration in question", and section 6A(2) makes clear that agreeing a law for the wider contract is not by itself an agreement about the arbitration agreement. The Act received Royal Assent on 24 February 2025 and came into force on 1 August 2025 under regulation 2 of the Arbitration Act 2025 (Commencement) Regulations 2025, SI 2025/905. Under section 17(4) of the 2025 Act the new rule does not reach arbitral proceedings commenced before that date, court proceedings connected with them, or other court proceedings begun before it — those are still read the UniCredit way — and otherwise applies to an arbitration agreement whenever made. A clause signed years ago that names only the law of the contract therefore points to the law of the seat in an arbitration started now; parties who want anything else need an express choice of law for the arbitration agreement itself.

Interim relief: freezing assets before there is a decision

Between filing and judgment, a defendant can move money. The main protective tool in common-law forums is the freezing order (historically the Mareva injunction), granted in England under section 37 of the Senior Courts Act 1981 and, for a worldwide freezing order, reaching assets anywhere. The applicant must show a good arguable case on the merits — "more than barely capable of serious argument," not necessarily better than even — and a real risk of dissipation established "on solid evidence," not mere suspicion; the court then asks whether an order is just and convenient. Because these orders are usually sought without notice, the applicant owes a duty of full and frank disclosure, and must give a cross-undertaking in damages to compensate the respondent (and often third parties, such as banks) if the order proves unjustified.

Within the EU, Article 35 of Brussels Ia lets a party apply "to the courts of a Member State for such provisional, including protective, measures as may be available under the law of that Member State, even if the courts of another Member State have jurisdiction as to the substance" — so an asset in Germany can be frozen by a German court while the merits run in Ireland.

Within the EU there is also a targeted instrument for the commonest asset of all — a bank account. Regulation (EU) No 655/2014 creates the European Account Preservation Order, granted without notice to the debtor and served on the bank rather than on the debtor.

Article 7(1) sets the test: the creditor must satisfy the court "that there is an urgent need for a protective measure in the form of a Preservation Order because there is a real risk that, without such a measure, the subsequent enforcement of the creditor's claim against the debtor will be impeded or made substantially more difficult"; where no judgment has yet been obtained, Article 7(2) adds that the creditor must show he "is likely to succeed on the substance of his claim against the debtor".

Article 12 makes security from the creditor the rule before judgment and a discretion after it, and Article 14 lets a creditor with an enforceable title ask the court to trace the debtor's accounts through a designated information authority. Denmark sits outside it: by recital 51 Denmark "is not taking part in the adoption of this Regulation and is not bound by it or subject to its application".

There is a further trap in the treaty layer. Interim measures fall outside the main recognition conventions. Article 7 of the 2005 Choice of Court Convention states that "interim measures of protection are not governed by this Convention," and the 2019 Judgments Convention likewise does not cover them. A freezing order is therefore only as good as the willingness of each court where an asset sits to grant or mirror it; you cannot assume a foreign court will carry your freeze across the border automatically.

Court judgment or arbitral award: the fork that shapes enforcement

The instrument you end up holding is set by the dispute-resolution clause, and it changes everything downstream. The table sets the two paths against the same axes so the trade-off is visible before the detail.

The practical lesson is that arbitration is chosen in cross-border deals less for the hearing than for the exit: the award enforces in the counterparty's country whether or not that country would ever have honoured a foreign court judgment. That advantage is real but not unconditional — the New York Convention has its own defences, examined below. Which arbitration to write into the clause is a separate question from this fork, and it is decided on different axes: the seat and its annulment court, the speed and price of an emergency arbitrator, the expedited threshold, whether the rules bind the parties to confidentiality, and whether a sanctioned counterparty can lawfully pay the institution at all. Those are compared institution by institution, on published fee scales, in choosing a forum for a private-capital dispute.

Recognition and enforcement of judgments: routes by instrument

For a court judgment, there is no default. You identify which route connects the origin country to the country where the assets sit, and each route carries its own conditions and its own timing rules. The table compares the main routes on the same axes; the paragraphs after it explain the elimination logic.

Between EU Member States the route is the strongest that exists for judgments: under Article 36 a judgment is recognised without any special procedure, and under Article 39 an enforceable judgment "shall be enforceable in the other Member State without any declaration of enforceability being required" — the old exequatur step is gone. Refusal is confined to Article 45: manifest breach of public policy, a default judgment where the defendant was not served in time to defend, irreconcilability with another judgment between the same parties, or conflict with the protective jurisdiction rules for insurance, consumer and employment contracts or with the exclusive-jurisdiction rules of Article 24.

Where the parties agreed an exclusive court in a contract, the 2005 Choice of Court Convention is usually the cleanest cross-border route, because Article 8 obliges recognition and Article 9 lists a short, closed set of refusals. It does not help with non-exclusive or asymmetric clauses, which fall outside it.

The 2019 Judgments Convention is the newest and broadest judgment treaty, but two limits recur. First, the judgment must fit one of the Article 5 jurisdictional "filters" — for example, the defendant was habitually resident in the origin State, or the contractual obligation was performed there — so a judgment from a court the debtor never accepted may not qualify. Second, its temporal rule (Article 16) is unforgiving: it applies only if the Convention was already in force between both states when the origin proceedings began. For the United Kingdom that means only proceedings started on or after 1 July 2025 benefit, so older English judgments still fall back to other routes. Its reach is also still small and still moving: the HCCH status table records 33 Contracting Parties, with Albania and Montenegro bound from 1 March 2026 and Andorra from 1 June 2026, so a country pair that failed the test last year can pass it this year.

Two routes sit between the treaty regimes and the residual national rules, and both are routinely missed. The 2007 Lugano Convention (OJ L 339, 21.12.2007, p. 3) still governs the EU–EFTA/EEA relationship on Brussels lines but with the older machinery: Article 33(1) recognises a judgment "without any special procedure being required", while Article 38(1) still requires that it be "declared enforceable there" before enforcement. It is closed to the United Kingdom for now — assessing the UK application to accede, the European Commission concluded on 4 May 2021 that the Convention "is a flanking measure of the internal market and relates to the EU-EFTA/EEA context", that in relation to all other third countries "the consistent policy of the European Union is to promote cooperation within the framework of the multilateral Hague Conventions", and recommended that consent be withheld (COM(2021) 222 final).

For judgments from designated Commonwealth and treaty countries, England offers registration rather than a fresh action: section 9 of the Administration of Justice Act 1920 allows registration "at any time within twelve months after the date of the judgment, or such longer period as may be allowed by the court", with refusal confined to the grounds in section 9(2), and section 2 of the Foreign Judgments (Reciprocal Enforcement) Act 1933 gives six years from the date of the judgment.

Timing is a defence in its own right, not an administrative detail. Under section 24(1) of the Limitation Act 1980, "an action shall not be brought upon any judgment after the expiration of six years from the date on which the judgment became enforceable", and section 24(2) bars recovery of any arrears of judgment interest more than six years after that interest fell due. A creditor who spends four years tracing assets and two more negotiating can find there is nothing left to sue on — which is why tracing and enforcement are run in parallel and not in sequence.

When no treaty connects the pair, you are on the requested country's own rules, and this is where the England–UAE example bites. Onshore, since the UAE Ministry of Justice letter of 13 September 2022 — prompted by the English decision in Lenkor Energy Trading DMCC v Puri [2020] EWHC 75, which had enforced a Dubai judgment in England — Dubai courts may find the reciprocity that UAE civil-procedure law requires and enforce an English money judgment without re-trying the merits. In parallel, the DIFC Courts act as a conduit: a creditor obtains recognition in the DIFC, the recognised judgment becomes a DIFC judgment, and it is then referred for execution to the Dubai Courts under Article 7 of the Judicial Authority Law (Dubai Law No 12 of 2004, as amended). The DIFC's own Chief Justice has cautioned that a creditor using the conduit "will seek enforcement … at its own risk," because the DIFC cannot control how the onshore court handles the referral — a reminder that even a working route is not a guarantee.

Enforcing arbitral awards and the defences that survive

Under the New York Convention, enforcement is the rule and refusal the narrow exception. Article III requires each Contracting State to recognise awards as binding and enforce them under its own procedure, with no conditions "substantially more onerous" than for domestic awards. Article IV sets the minimal paperwork: the authenticated award and the arbitration agreement. Everything a resisting party can raise is in Article V, and the list is closed:

• V(1)(a) — a party was under an incapacity, or the arbitration agreement was invalid;
• V(1)(b) — a party was not given proper notice or could not present its case;
• V(1)(c) — the award decides matters beyond the scope of the submission;
• V(1)(d) — the tribunal's composition or the procedure departed from the parties' agreement;
• V(1)(e) — the award has not yet become binding, or has been set aside or suspended by a court at the seat;
• V(2)(a) — the subject matter is not arbitrable under the law of the enforcing country;
• V(2)(b) — enforcement would be contrary to that country's public policy.

Two of these are where enforcement genuinely fails. The seat matters because Article V(1)(e) lets the enforcing court refuse an award that the courts of the seat have annulled: choosing the seat is choosing the only place that can set the award aside, which is why London, Paris, Geneva and Singapore are picked deliberately. Public policy under V(2)(b) is meant to be exceptional, but it is the defence most often argued, and its content is decided by the enforcing country — an award perfectly valid at the seat can meet resistance where the assets are if it collides with a mandatory rule there. Article VII preserves any more favourable enforcement right the creditor has under other treaties or the local law, so a creditor is never worse off for invoking the Convention.

What the resisting party actually does

A debtor rarely argues Article V in the abstract. It runs two tracks at once, and the Convention anticipates both. The first is the set-aside application at the seat, because Article V(1)(e) is the only ground that can kill the award everywhere rather than in one country. At an English seat the window is short: section 70(3) of the Arbitration Act 1996 requires any application or appeal under sections 67, 68 or 69 to be brought "within 28 days of the applicable date", and a new subsection (3A), in force from 1 August 2025, now spells out what that date is.

The second track is delay at the place of enforcement. Article VI of the New York Convention allows the authority before which the award is relied upon, where a set-aside application "has been made to a competent authority referred to in article V (1) (e)", to "adjourn the decision on the enforcement of the award" and, "on the application of the party claiming enforcement of the award, order the other party to give suitable security"; England enacts this in section 103(5) of the Arbitration Act 1996. The practical rule for a creditor is to ask for security whenever an adjournment is sought, because an adjournment without security is a free option for the debtor.

The enforcing court decides the agreement for itself. Article V(1)(a) is not a review of the tribunal's reasoning; it is a rehearing. In Dallah Real Estate and Tourism Holding Company v Ministry of Religious Affairs, Government of Pakistan (UK Supreme Court, 3 November 2010, [2010] UKSC 46) the claimant sought to enforce an ICC award made in Paris against the Government of Pakistan, which had never signed the contract containing the arbitration clause. The Supreme Court held that under section 103(2)(b) of the Arbitration Act 1996, which enacts Article V(1)(a), the enforcing court makes its own independent determination whether a binding arbitration agreement existed, and the tribunal's own finding on its jurisdiction carries no binding or special evidential weight however carefully reasoned. Applying French law as the law of the seat, the Government was not a party, and enforcement was refused. The lesson runs backwards into drafting: the identity of the counterparty on the arbitration agreement is verified at signature, not at enforcement.

Two smaller points change outcomes more often than they should. Under Article I(3) a state may accede with the reciprocity reservation, applying the Convention only to awards made in the territory of another Contracting State, or with the commercial reservation, applying it only to relationships considered commercial under its own law — so the reservations of the country where the assets sit are checked before the seat is chosen, not after. And Article VII(1) preserves any right the creditor has "to avail himself of an arbitral award in the manner and to the extent allowed by the law or the treaties of the country where such award is sought to be relied upon": where local law is more generous than the Convention, the creditor may use local law instead.

When the debtor is a state: two immunities, and the ICSID route

A judgment or award against a state, a ministry, a central bank or a state-owned company meets a defence no commercial debtor has. Sovereign immunity is not one rule but two, waived separately: immunity from jurisdiction — may the court hear the case at all — and immunity from execution — may anything be seized once you have won. Agreeing to arbitrate answers the first question and says almost nothing about the second.

Read the table down the rows, not across them: each row is a separate permission that has to be obtained on its own facts. A state that signed an arbitration clause has waived immunity from jurisdiction for proceedings relating to that arbitration and has waived nothing at all about its embassy accounts, its reserves or its aircraft.

Investment awards under the ICSID Convention sit one step further along, and the step is only half a step. Article 53 makes the award binding and provides that it "shall not be subject to any appeal or to any other remedy except those provided for in this Convention"; Article 54 requires every Contracting State to enforce the pecuniary obligations "as if it were a final judgment of a court in that State", with no Article V-style list of defences at all, so recognition is close to ministerial. Article 55 then gives it back at the sharp end: "Nothing in Article 54 shall be construed as derogating from the law in force in any Contracting State relating to immunity of that State or of any foreign State from execution." An ICSID award is therefore the easiest instrument in the world to have recognised and no easier than any other to execute.

One award, two courts, opposite answers. The Micula litigation shows what that costs in practice. In Micula v Romania (UK Supreme Court, 19 February 2020, [2020] UKSC 5) the Court lifted a stay on enforcement of an ICSID award registered under the Arbitration (International Investment Disputes) Act 1966, holding that the United Kingdom's EU-law duty of sincere co-operation was constrained by article 351 TFEU, which preserved obligations under the ICSID Convention entered into before accession; the stay could not stand. Less than two years later the Court of Justice, sitting as a Grand Chamber, answered the EU-law side the other way: in European Commission v European Food SA and Others (25 January 2022, Case C-638/19 P) it set aside the General Court's judgment, itself rejected the pleas denying the Commission's competence under Article 108 TFEU, and referred the remaining pleas — whether the payment actually meets the State-aid conditions of Article 107(1) TFEU — back to the General Court. The Commission was competent, the Court held, because the right to the compensation was granted only by the award, after Romania's accession on 1 January 2007, so paying it falls to be assessed under the EU State-aid rules. Same award, two courts, two answers: the enforcing court asked whether a treaty older than EU membership compelled enforcement, the Union court asked whether payment was lawful under EU law. A creditor holding an award against an EU Member State has to win both questions, in different forums, and can lose the second after winning the first.

Asset tracing and collectability: the last mile

A decision is worth what can be executed against it, and execution needs assets you can find and reach. Asset tracing — identifying what the debtor owns and where — comes first, and courts assist it: post-judgment disclosure orders, orders against banks and other third parties, and, in England, the disclosure obligations attached to a freezing order. Because execution is territorial, the location of assets drives the choice of enforcing forum as much as the merits do: there is little point in a beautifully reasoned judgment enforceable only where the debtor keeps nothing.

Collectability is the separate, blunt question of whether the debtor can actually pay. A solvent debtor with reachable assets in a cooperative jurisdiction is collectable; a debtor whose wealth sits behind opaque structures, in non-cooperating states, or in assets held by third parties, may not be — whatever the judgment says. Several recurring facts defeat collection even after a win:

• assets held through a chain of holding companies or a trust, so the debtor named in the judgment is not the legal owner of anything worth taking — the reason ownership, control and economic interest must be distinguished from the outset, and the reason a discretionary structure settled years before the dispute raises a different question altogether — whether the structure itself is attackable, not whether the judgment is good (see asset protection trusts);
• assets in the hands of an intermediary, such as securities held in a custody chain, where reaching them means enforcing against the account and the custodian's own jurisdiction, not just the debtor (see securities custody);
• assets frozen for a reason unrelated to your claim, for example under a sanctions designation, where the block is administrative and your judgment does not release it (see the sanctions map);
• an intervening insolvency, which converts individual enforcement into a collective process and can claw back a late-granted security or a preferential transfer (see cross-border insolvency and the avoidance of prior transactions).

Adjacent problems have their own owners. Tax-treaty disputes run through the mutual-agreement and arbitration machinery covered in tax disputes, not through this page; the jurisdiction and recognition of a divorce or a maintenance order are handled in cross-border divorce jurisdiction; the recognition of a foreign trust as a structure is a Hague 1985 question covered in recognition of foreign trusts. This page owns the general civil and commercial chain — jurisdiction, parallel proceedings, interim relief, judgment or award, recognition, enforcement and collection; the route map by legal problem sorts a new matter to the right owner before any of that starts.
