The central point: the High Court held that appointing post-judgment receivers over VietJet’s assets outside Vietnam was appropriate in principle to assist enforcement of an English judgment debt exceeding US$250 million. The final decision to make the receivership order was deferred pending further evidence on costs and proportionality.
This is a significant judgment on the English court’s willingness to use equitable execution to enforce substantial judgments against foreign assets where conventional enforcement has encountered serious obstacles.
1. Background and procedural history
The dispute arose from sublease agreements relating to four Airbus A321 aircraft. FW Aviation Holdings 1 Limited (FWA), having acquired rights under the relevant financing arrangements, brought proceedings against VietJet Aviation Joint Stock Company.
The underlying litigation produced several judgments:
Liability: FWA substantially succeeded at the first trial in 2024. The Court of Appeal dismissed VietJet’s appeal, and permission for a further appeal was refused.
Quantum: A judgment in April 2025 resulted in an order for approximately US$181.5 million. Payment was subsequently structured in three instalments.
Further sums: Additional orders included approximately US$35.1 million for default interest and costs, while a further judgment in July 2026 awarded approximately US$18.3 million in lost rental.
By the time of the receivership application, the total judgment debt exceeded US$250 million. VietJet had paid only about US$2 million against the relevant outstanding amounts, despite the payment obligations being established by judgments which it could no longer appeal.
FWA had also tried to enforce the judgments in several jurisdictions, including Vietnam, Australia, France, Malaysia, Singapore, Ireland and the United States. Those efforts had encountered significant legal and practical difficulties.
The application was therefore an attempt to secure a more effective means of enforcement, rather
than to relitigate VietJet’s liability.
2. The legal framework
The application was made under section 37(1) of the Senior Courts Act 1981, which empowers the High Court to appoint a receiver where it is just and convenient to do so.
CPR Practice Direction 69.5 identifies three matters to which the court must have regard when considering receivership as a means of enforcing a judgment:
1. The amount claimed by the judgment creditor.
2. The amount likely to be obtained by the receiver.
3. The probable costs of the appointment.
The appointment is a form of equitable execution. Rather than relying exclusively on conventional enforcement mechanisms, a receiver may be appointed to identify, monitor, collect or realise assets and rights for the benefit of the judgment creditor.
The important qualification is that a receivership is not automatic, merely because a judgment remains unpaid. The court must assess whether the remedy is likely to assist enforcement, whether it is just and convenient, and whether its costs are proportionate.
3. Why did Butcher J consider receivership appropriate?
The judge gave several reasons:
A. The judgment debt was established and substantially unpaid
The starting point was that VietJet owed a substantial debt under final English judgments. English law favours compliance with judgments and, where necessary, their enforcement.
The court was not persuaded that VietJet’s continued failure to pay could be justified simply by the difficulties encountered in enforcing the judgments abroad.
B. Conventional enforcement had encountered serious obstacles
FWA had pursued enforcement proceedings in numerous jurisdictions without achieving significant recovery.
A particularly important difficulty was the refusal of the Vietnamese courts to recognise the English judgment. Vietnam was also where most of VietJet’s assets were apparently located.
The judge nevertheless held that the difficulties of enforcement supported the case for receivership over assets elsewhere. VietJet’s right to contest enforcement under the laws of foreign jurisdictions did not alter the practical fact that those proceedings had obstructed FWA’s attempts to recover the
judgment debt.
C. Receivers could deal with assets that ordinary execution might not reach effectively
This was a particularly important feature of the judgment. VietJet’s potentially valuable assets were not confined to cash or physical property which could
readily be seized. They included contractual rights that would produce payments or deliveries in the future.
The judge identified several potentially valuable categories:
– Aircraft and engine purchase rights
– Contractual rights under aircraft purchase agreements with Boeing and Airbus, including potential value arising from favourable purchase prices, discounts or the market value of aircraft at delivery.
– Pre-delivery payments (PDPs)
– Payments made towards future aircraft deliveries, potentially recoverable in certain circumstances or realisable when aircraft are delivered.
– Lease deposits
– Contractual rights to repayment of deposits at the end of aircraft leases, subject to the relevant contractual conditions.
– Maintenance reserves
– VietJet’s accounts as at 30 June 2026 showed approximately US$300 million receivable in maintenance reserves within 12 months. The precise contractual entitlement could be disputed, but the judge considered there were substantial arguments that these were assets
potentially amenable to receivership.
The receivers could identify such rights, monitor when they became enforceable or payable, and take steps to collect or secure them. The court was satisfied that there was at least a reasonable prospect that this would improve FWA’s recovery prospects.
4. Could the English court appoint receivers over foreign assets?
Yes, in principle. This is one of the judgment’s most significant aspects.
VietJet’s assets were predominantly outside England. The judge held that the proposed order nevertheless had a sufficient connection with the English court, particularly because VietJet had submitted to its jurisdiction and participated in the underlying proceedings. The judge also considered the distinction between an order operating in personam and one purporting directly to alter proprietary rights in foreign assets.
The receivership order would operate personally against VietJet. It would not, simply by being made in England, automatically transfer ownership of assets abroad or bind every foreign third party.
The judge considered that the order could still have practical utility even if foreign recognition were not obtained everywhere. Ancillary orders and the possibility of contempt proceedings in England could encourage compliance by parties subject to the court’s jurisdiction.
There was, in the judge’s view, a reasonable prospect of recognition in certain jurisdictions, particularly France, Ireland, Australia and the British Virgin Islands. That was an assessment of the evidence before him, not a determination that recognition was guaranteed in those jurisdictions.
5. Why were assets in Vietnam excluded initially?
The judge did not treat the Vietnamese courts’ refusal to recognise the English judgments as undermining their validity under English law.
However, he recognised a separate issue of international comity: the risk that an English receivership order covering VietJet’s assets in Vietnam might be perceived as interfering with the decision-making processes of the country with which the airline had its closest connections. He therefore adopted an incremental approach, drawing on the approach in Masri v Consolidated Contractors International Sal [2008] EWHC 2492 (Comm).
The initial order was to exclude assets located in Vietnam. The judge expressly left open the possibility of extending the receivership to those assets at a later stage if experience showed that justice required it.
Importantly, he considered that excluding Vietnam made a broadly framed order over assets elsewhere more justifiable.
Objection 1: The order will be unprecedented
Judge’s approach 1: The potentially exceptional circumstances did not prevent the court granting relief where it was otherwise justified.
Objection 2: Vietnam had refused recognition of the English judgments
Judge’s approach 1: This did not undermine the judgments’ validity under English law or preclude receivership over assets elsewhere.
Objection 3: Receivership would disrupt the airline’s business.
Judge’s approach 3: This carried little weight given the outstanding judgment debt and the absence of concrete arrangements for payment.
Objection 4: The appointment could trigger contractual defaults or termination rights.
Judge’s approach 4: The judge noted that VietJet said such rights had already accrued as a result of the judgments, without meaningful business impact.
Objection 5: The proposed order was too broad.
Judge’s approach 5: The judge considered a broadly framed order justifiable, subject to excluding Vietnam-located assets initially and settling the precise terms.
Objection 6: The likely costs had not been adequately evidenced.
Judge’s approach 6: This was a material outstanding issue. Further evidence and submissions were required before the court could decide whether to make the final order.
This is a measured approach to extraterritorial enforcement: the court was willing to act beyond England, but sought to limit the immediate risk of conflict with another state’s judicial processes.
The judge also required protections for third parties, including provisions commonly known as Babanaft and Baltic provisos. These are intended to limit the order’s effects on third parties and assets in circumstances where the English court’s order should not operate extraterritorially.
6. The outstanding issue: proportionality of costs
This is an important qualification to the result.
FWA had argued that, given a judgment debt exceeding US$250 million, the proportionality of receivership costs was effectively self-evident. VietJet argued that the court could not properly assess the application without evidence of the probable costs.
After the hearing, FWA submitted further evidence setting out illustrative low, medium and high monthly costs, although the estimates were non-binding and the evidence was challenged by VietJet.
Rather than dismiss the application or make an unconditional order, Butcher J decided that:
– FWA could rely on the additional evidence and submit limited further evidence.
– VietJet could respond on the issue of probable costs.
– The court would then decide whether the order should be made on paper or following a further hearing.
The judge’s conclusion was that receivership was appropriate in principle, subject to being satisfied about the proportionality of its probable costs and the detailed terms of the order. The final receivership order had not yet been made in the judgment itself.
7. Significance for English commercial litigation
In my view, the judgment is particularly useful in five respects.
1. It reinforces the availability of receivership as a substantial enforcement tool. A judgment creditor need not be confined to conventional execution where the nature of the debtor’s assets or practical obstacles make those methods ineffective.
2. It supports receivership over foreign assets where the English court has a sufficient jurisdictional connection. The debtor’s submission to the English court’s jurisdiction and the enforcement purpose of the order were important.
3. It highlights the importance of future contractual rights as assets. Rights to future payments, refunds, deliveries or other benefits may provide an avenue for recovery even where there is no immediately realisable cash or physical property.
4. Non-recognition abroad is not necessarily fatal. The English court may make an order operating personally against a debtor even where the underlying judgment cannot be enforced through the ordinary process in a particular foreign jurisdiction. That does not, however, guarantee local effectiveness or recognition.
5. Proportionality remains a real constraint. The size of the judgment debt is important, but the creditor should be prepared to provide credible evidence of the likely costs, the potential value of the assets and the practical utility of the proposed appointment.
Conclusion
FW Aviation v VietJet is a useful authority for the proposition that the English High Court can use post-judgment receivership to overcome serious obstacles to enforcement, including where the relevant assets are foreign and consist of future contractual rights rather than immediately realisable property.
The court’s approach was robust but measured: it was prepared to approve receivership in principle over assets outside Vietnam, while protecting international comity by initially excluding Vietnamese assets and preserving a proper assessment of costs.
For a judgment creditor facing an uncooperative foreign debtor, the case provides a strong basis for considering receivership as part of an enforcement strategy. It does not establish that receivership will automatically be available, or effective in every foreign jurisdiction.
