Enforcing a United Kingdom Court Judgment in USA

Enforcing a United Kingdom court judgment in the USA is achievable, but it requires navigating a patchwork of state laws rather than a single federal treaty. The United States has no bilateral enforcement treaty with the United Kingdom, so a creditor must convert the UK judgment into a US judgment through a domestic court action in the state where the debtor holds assets. This guide explains the recognition procedure, the legal standards applied by US courts, the practical timeline and cost picture, the defences a debtor can raise, and the strategic choices that determine whether enforcement succeeds.

The absence of a bilateral treaty between the United Kingdom and the United States is the single most important structural fact for any creditor. Unlike enforcement between EU member states, where reciprocal frameworks once applied, the US-UK relationship relies entirely on the common law doctrine of comity and, in most states, on codified versions of that doctrine.

The majority of US states have adopted either the Uniform Foreign-Country Money Judgments Recognition Act of 1962 or its revised version from 2005. Both versions establish a presumption in favour of recognising foreign money judgments that are final, conclusive and enforceable in the originating country. UK judgments from the High Court, the Court of Appeal and the UK Supreme Court generally satisfy these criteria without difficulty. County Court judgments and tribunal awards require more careful analysis, because a US court will scrutinise whether the originating forum had proper jurisdiction under US standards.

A non-obvious requirement is that only money judgments are routinely recognised. Injunctions, specific performance orders and declaratory judgments issued by UK courts are not covered by the Uniform Acts and face a much harder path through US courts, which treat equitable relief from foreign tribunals with considerable caution.

Because the USA has no federal enforcement mechanism for foreign judgments, the creditor must file in a state court - or, where diversity jurisdiction applies, in a federal district court sitting in that state - in the jurisdiction where the debtor has attachable assets. This choice is strategic, not merely administrative.

States that have adopted the revised 2005 Uniform Act, including California, Michigan and Colorado, apply a relatively creditor-friendly framework with clear procedural rules. States that still operate under the 1962 Act or under pure common law, such as New York and Texas, are also well-developed forums with extensive case law on UK judgments specifically. New York courts have a long track record of recognising English commercial judgments, and the New York courts are frequently chosen when the debtor has bank accounts or real property in that state.

In practice, founders and creditors should consider the following factors when selecting a forum:

• Where the debtor's bank accounts, real estate or receivables are located.
• Whether the state has adopted the 2005 or 1962 Uniform Act, or operates under common law.
• The local court's familiarity with UK commercial judgments.
• Whether the debtor has a registered agent or principal place of business in that state, which simplifies service.

A common mistake is filing in a state where the creditor's own lawyers are based rather than where the debtor's assets actually sit. This wastes time and money on a judgment that cannot be executed locally.

Enforcing a UK judgment in the USA involves a two-stage process. First, the creditor obtains recognition of the UK judgment as a valid US judgment. Second, the creditor executes against the debtor's assets using the enforcement tools available under that state's law.

Stage one: filing the recognition action

The creditor files a complaint or petition in the appropriate state or federal court, attaching a certified copy of the UK judgment and, where required, an apostille or authentication under the Hague Apostille Convention. The United Kingdom is a signatory to the Hague Convention of 1961, so obtaining an apostille from the Foreign, Commonwealth and Development Office is straightforward and typically takes a few days to a couple of weeks.

The complaint must allege that the UK judgment is final, conclusive and enforceable in England and Wales (or Scotland or Northern Ireland, as applicable), that the originating court had jurisdiction, and that none of the statutory grounds for non-recognition apply. The creditor should attach a legal opinion or certified statement confirming the judgment's status under UK law, as US courts frequently request this evidence.

The debtor is served under the applicable state rules. In an uncontested case, recognition can be obtained in as little as four to eight weeks. In a contested case, where the debtor raises defences, the timeline extends to six to eighteen months, depending on the court's docket and the complexity of the arguments.

Stage two: execution against assets

Once the US court enters a judgment recognising the UK award, the creditor holds a domestic US judgment and can use all standard enforcement tools: bank levies, garnishment of wages or receivables, liens on real property, and writs of execution against personal property. The specific tools and their procedural requirements vary by state. California, for example, has detailed rules on judgment liens against real property under the California Code of Civil Procedure, while New York's CPLR Article 52 governs enforcement proceedings in that state.

The Uniform Acts and common law both identify mandatory and discretionary grounds for refusing to recognise a foreign judgment. Understanding these defences is essential for assessing the risk before investing in enforcement proceedings.

Mandatory grounds for refusal include:

• The UK judgment was rendered without due process - for example, the defendant was not given adequate notice or an opportunity to be heard.
• The UK court lacked personal or subject-matter jurisdiction under US standards.
• The judgment was obtained by fraud.
• The judgment conflicts with another final judgment entitled to recognition.
• The underlying claim is repugnant to US public policy.

Discretionary grounds include situations where the UK court lacked impartial tribunals or procedures compatible with due process, or where the parties had agreed to resolve disputes exclusively in a US forum.

In practice, the public policy defence is the most frequently raised but the least often successful. US courts interpret public policy narrowly and will not refuse recognition simply because the outcome differs from what a US court might have reached. A creditor should, however, be alert to judgments that include punitive damages elements, as some US states will recognise only the compensatory portion of a foreign award.

A common mistake made by foreign creditors is underestimating the jurisdictional challenge. If the UK court's jurisdiction rested on service of process within England on a defendant who had no other connection to the jurisdiction, a US court applying its own jurisdictional standards may find that basis insufficient. Creditors should review the jurisdictional basis of the UK judgment before filing in the USA.

Scenario one: English High Court commercial judgment, debtor with US bank accounts

A UK-based supplier obtains a High Court judgment in the Commercial Court against a US-incorporated buyer for unpaid invoices. The judgment is final and unappealed. The debtor has a bank account in New York and a subsidiary registered in Delaware. The creditor files a recognition action in New York state court under New York's version of the 1962 Uniform Act, attaches an apostilled copy of the judgment, and serves the debtor through its registered agent in Delaware. The debtor does not contest recognition. The New York court enters a recognition order within approximately six weeks. The creditor then serves a restraining notice on the debtor's bank under CPLR 5222 and proceeds to levy the account. Total elapsed time from filing to funds: roughly three to four months.

Scenario two: contested recognition, debtor raising jurisdictional defence

A UK technology company obtains a judgment in the English courts against a California-based licensee for breach of a software licence agreement. The licence agreement contained an English jurisdiction clause, but the defendant argues that the clause was not properly incorporated and that the English court therefore lacked jurisdiction. The defendant raises this as a defence in the California recognition proceedings. The California court holds an evidentiary hearing, reviews the licence agreement and the English court's jurisdictional ruling, and ultimately recognises the judgment - but only after fourteen months of litigation. Professional fees in contested proceedings of this kind are substantially higher than in uncontested cases.

The cost of enforcing a UK judgment in the USA depends primarily on whether the debtor contests recognition and on the complexity of the execution phase.

In an uncontested recognition proceeding, professional fees typically start from the low thousands of USD for straightforward cases in creditor-friendly forums. Court filing fees and authentication costs add a modest further amount. The total elapsed time is commonly four to ten weeks from filing to a recognition order.

In a contested proceeding, professional fees can reach the mid-to-high tens of thousands of USD or more, depending on the number of hearings, the need for expert evidence on UK law, and the duration of the litigation. Creditors should budget for the possibility of an appeal by the debtor, which can add a further six to twelve months and a significant further cost increment.

Execution costs - levying bank accounts, enforcing liens, pursuing garnishment - are additional and vary by state. Many US enforcement attorneys work on a contingency or hybrid fee basis for the execution phase, which can reduce the creditor's upfront exposure.

Many creditors underestimate the cost of obtaining and authenticating the UK judgment documents to US standards. An apostille, certified translations where needed, and a legal opinion on the judgment's finality under UK law are all necessary and should be budgeted from the outset.

A creditor's strategic decisions before and during UK litigation can significantly affect the ease of US enforcement later.

Preserve the jurisdictional record. Ensure that the UK court's jurisdiction is clearly established on the face of the judgment or in the accompanying reasons. If the defendant appeared and contested the merits, that appearance will generally preclude a later jurisdictional challenge in the USA. If the defendant defaulted, the creditor should ensure the record shows proper service and notice.

Obtain a judgment in the correct form. US courts require a money judgment that states a specific sum. A UK judgment that awards damages "to be assessed" is not yet enforceable in the USA; the creditor must first obtain a quantum judgment before filing in the US.

Identify assets before filing. Asset tracing before commencing US proceedings avoids filing in the wrong state. US discovery tools - including subpoenas to banks and third parties - are available post-recognition to locate assets, but pre-filing intelligence saves time and cost.

Consider interim measures. In some states, a creditor can apply for a temporary restraining order or attachment at the time of filing the recognition action, before the debtor has notice. This prevents dissipation of assets during the recognition proceedings. The availability and standard for such relief varies by state.

Register in multiple states if necessary. If the debtor has assets in several states, the creditor may need to register the US judgment in each state separately. Most states have adopted the Uniform Enforcement of Foreign Judgments Act, which allows a judgment from one US state to be registered in another with minimal additional proceedings.

What is the risk that a US court will refuse to recognise a UK judgment on public policy grounds?

The public policy defence is available under both the Uniform Acts and common law, but US courts apply it narrowly. A US court will not refuse recognition simply because the English law applied differs from US law or because the damages awarded are higher than a US court might have granted. The defence is most likely to succeed where the judgment involves a claim that is fundamentally contrary to US constitutional principles or where the underlying conduct is illegal under US law. In practice, standard commercial judgments from English courts - for debt, breach of contract or damages - rarely face a successful public policy challenge. Creditors should, however, review any punitive or exemplary damages element separately, as some states limit recognition of non-compensatory awards.

How long does the full enforcement process typically take, and what drives the timeline?

In an uncontested case with a straightforward money judgment and identifiable assets, the full process from filing the recognition action to receiving funds can take as little as three to five months. The main variables are whether the debtor contests recognition, the court's docket in the chosen state, and the speed with which assets can be located and levied. A contested recognition proceeding adds six to eighteen months. Execution against real property is slower than levying a bank account, because it typically involves a sheriff's sale process with mandatory notice periods. Creditors should plan for a realistic minimum of four to six months even in favourable circumstances.

Should the creditor pursue enforcement in the USA or consider other options, such as re-litigating the claim in a US court?

Re-litigating the underlying claim in a US court is almost always more expensive and slower than seeking recognition of the existing UK judgment. The UK judgment can be used as strong evidence in any fresh US proceedings, but starting from scratch means full discovery, trial preparation and the risk of a different outcome. Recognition proceedings, even contested ones, are generally faster and cheaper than fresh litigation. The main exception is where the UK judgment has a significant defect - for example, a jurisdictional basis that is clearly insufficient under US standards - in which case the creditor may be better served by commencing a new action in the USA based on the underlying contract or tort claim. A creditor facing this situation should obtain a US legal opinion on the strength of the recognition case before deciding which route to pursue.

Enforcing a UK court judgment in the USA is a structured, achievable process for creditors who understand the state-by-state framework and prepare their case carefully. The absence of a bilateral treaty means that success depends on choosing the right forum, presenting the judgment in the correct form, and anticipating the defences a debtor may raise. Uncontested cases can move quickly; contested cases require patience and a realistic budget.
