Korea’s Supreme Court holds foreign provisional attachments have no effect in Korea — creditors must secure Korean assets through Korean courts.
In brief
A favorable ruling from a foreign court or arbitral tribunal is often only the first step in a cross-border recovery strategy. Where the counterparty’s assets are located in Korea, the creditor must separately navigate Korea’s own recognition and enforcement framework — and that framework has just become clearer on a question that had remained open for decades.
In Judgment 2025Da211405 dated 14 May 2026, the Supreme Court of Korea held for the first time that a foreign court’s provisional attachment order is not a “final and conclusive judgment or a ruling of equivalent effect” eligible for recognition under Article 217 of the Civil Procedure Act. A foreign freezing-type order accordingly has no legal effect in Korea and cannot, by itself, preserve assets located there. Parties who need to secure Korean assets must apply for provisional relief directly to the Korean courts — ideally in parallel with the foreign proceedings, not after them.
Key takeaways
- A foreign court’s provisional attachment or similar interim protective order is not recognizable in Korea and confers no priority over Korean assets. As the decided case shows, a creditor that participates in a Korean distribution on the strength of such an order may be required to return the proceeds as unjust enrichment.
- Korean provisional attachment and provisional injunction remain fully available in support of foreign proceedings: Korean courts have long accepted that a merits action pending abroad sustains domestic provisional relief. Creditors litigating abroad can — and should — secure Korean assets through Korean courts from the outset.
- Parties to arbitration should take the same approach — and check their rules first. Korean court interim relief is in principle available whatever the seat (Arbitration Act, Articles 2(1) and 10), but Article 10 can be displaced by the parties’ chosen institutional rules; and interim measures of foreign-seated tribunals or emergency arbitrators have no enforcement route in Korea — a point a Korean court has already confirmed in respect of an SIAC emergency award (Cheongju District Court Decision 2022KaHap50245 dated 8 June 2023).
- The companion Supreme Court Judgment 2023Da295978 dated 30 April 2026 adds a second lesson: even a ruling that clears the eligibility threshold will be refused recognition where it collides with a prior final Korean decision. Where parallel proceedings are on foot, the sequence in which rulings become final can be decisive.
In more detail
1. One question, three regimes
Korean law does not treat every “favorable ruling obtained abroad” as a single category. Depending on what the party is holding, one of three regimes applies.
Foreign court judgments are governed by Article 217 of the Civil Procedure Act. Recognition is automatic — no declaratory proceeding is required — but only if four cumulative requirements are met: (i) the foreign court had international jurisdiction, assessed by Korean standards; (ii) the losing defendant was duly and timely served (service by publication does not count) or appeared and defended; (iii) recognition would not offend Korean public policy, with a specific statutory control for damages awards exceeding compensatory levels (Article 217-2); and (iv) reciprocity exists with the rendering jurisdiction — a requirement the Supreme Court construes liberally, without insisting on a treaty or an actual precedent of recognition (Supreme Court Judgment 2012Da23832 dated 30 May 2017). Compulsory enforcement additionally requires an enforcement judgment (exequatur) from a Korean court under Articles 26 and 27 of the Civil Execution Act, in which the merits of the foreign judgment may not be re-examined.
Foreign arbitral awards travel separately, under the New York Convention as implemented by the Arbitration Act. This route is generally more predictable than judgment enforcement — one reason arbitration remains attractive in Korea-related disputes — but it does not answer the question of how assets will be preserved while the dispute is pending.
Interim measures are the third category, and the unsettled one. Korean commentators had long debated whether a foreign court’s provisional attachment could be recognized; the prevailing view said no, because such orders are neither final nor conclusive, but the Supreme Court had never squarely ruled on the point. It now has.
2. The judgment: no recognition for foreign provisional attachments
Judgment 2025Da211405 arose from competing claims to a receivable payable in Korea. A UAE creditor had obtained a provisional attachment over the receivable from the Abu Dhabi courts, and later a final merits judgment in the UAE — but never brought that judgment to Korea for recognition and enforcement. A Korean creditor of the same debtor, relying on a domestic payment order, obtained a Korean assignment order over the same receivable — an order, comparable to a third-party debt order in English procedure, transferring the attached claim to the creditor in satisfaction of its debt. When the third-party obligor deposited the disputed funds with the court, the distribution allotted a share to the UAE creditor on the footing that its Abu Dhabi attachment deserved respect in Korea. The Korean creditor sued, arguing that the foreign attachment had no effect in Korea at all.
The Supreme Court agreed. A “final and conclusive judgment or a ruling of equivalent effect” under Article 217 means a decision of a foreign judicial body, rendered within its authority on a private-law matter, in proceedings that guarantee the parties an opportunity to present their case, and that finally determines the matter. A provisional attachment is, in the Court’s words, a protective ruling of a merely provisional nature — typically issued ex parte and liable to be varied or discharged as the merits develop — and so lacks precisely the two defining features: finality and a guaranteed adversarial process. The Abu Dhabi order therefore had no effect whatsoever in Korea; with no valid competing attachment in place, the Korean assignment order stood and transferred the receivable in full; and the UAE creditor was ordered to return its share of the distribution as unjust enrichment.
Two points deserve emphasis. First, the judgment does not leave foreign creditors without a route: a creditor in the UAE creditor’s position can apply for a Korean provisional attachment of its own while the foreign merits proceedings run and, once it holds a final judgment satisfying Article 217, proceed to exequatur. What it cannot do is skip both steps and rely on the foreign interim order — the loss here was one of sequencing, not an inevitability. Second, the outcome is unforgiving: the foreign attachment did not merely rank behind the Korean measure; it was treated as legally nonexistent, with restitution to follow.
3. The companion judgment: eligibility is only the first gate
Two weeks earlier, in Judgment 2023Da295978 dated 30 April 2026, the Supreme Court had refused an enforcement judgment for a California probate order appointing an administrator of a deceased’s estate with “full authority” under the Independent Administration of Estates Act. The Court held that the probate order was not an eligible basis for enforcement because it did not order a concrete, enforceable performance: the applicant was in substance asking the Korean court to authorize a compulsory sale of Korean real estate that went beyond anything the order itself conferred. Separately, the Court held that recognition would in any event offend Korean public policy, because a Korean family court had already, by a final ruling, appointed a different administrator for the same estate, and giving effect to the later foreign order would destabilize a status settled by a final Korean decision.
In making that assessment, a Korean court looks not only at the operative provisions of the foreign ruling but also at its reasoning and at the practical consequences of recognition — the standard drawn from Judgment 2018Da231550 dated 11 March 2022, in which the Court held that a Hawaii treble-damages judgment could not be refused recognition merely because it multiplied actual loss, given that Korean statutes now permit multiple damages in comparable regulatory fields.
Read together, the two 2026 judgments map the gatekeeping sequence. First, is the foreign ruling an eligible “final and conclusive judgment” at all — final, rendered with a guaranteed opportunity to be heard and, where enforcement is sought, containing concretely enforceable relief? Interim orders fail here. Second, does it satisfy the four recognition requirements, including public policy? Final judgments can still fail at this stage — although, as the treble-damages judgment shows, Korean public policy is applied with restraint and offers no refuge to judgment debtors merely dissatisfied with unfamiliar foreign remedies. Its real bite is reserved for genuine collisions, above all with prior final Korean rulings.
4. How Korea compares
Korea’s position sits squarely in the international mainstream. The 2019 Hague Judgments Convention — now in force for, among others, the EU and the United Kingdom — provides flatly that “an interim measure of protection is not a judgment” (Article 3(1)(b)), placing such measures outside the Convention altogether. Even within the EU, whose Brussels regime is the most integrated judgment-circulation system in existence, provisional measures circulate only if ordered by a court having jurisdiction as to the substance of the matter, and measures granted without summoning the defendant are denied cross-border effect unless served on the defendant before enforcement (Brussels I bis Regulation, Article 2(a)). Where interim measures do travel, in other words, it is by treaty — and adversarial process remains the price of admission.
Common-law jurisdictions have responded to the same problem not by importing the foreign order but by building a domestic channel. In England, section 25 of the Civil Jurisdiction and Judgments Act 1982 empowers the court to grant interim relief in support of foreign proceedings, and in Convoy Collateral Ltd v Broad Idea International Ltd [2021] UKPC 24 the Privy Council confirmed that a court with personal jurisdiction over a party may grant a stand-alone freezing injunction to protect the enforcement of a prospective or existing foreign judgment, even without a domestic cause of action against that party.
Korea reaches the same destination through its own doctrine. While foreign interim orders do not travel inbound, Korean provisional measures are available outbound — in aid of foreign proceedings. In a decision that remains the touchstone (Seoul Family Court Decision 2004JeuDan419 dated 16 August 2004), a debtor moved to cancel a Korean provisional attachment on the ground that the creditor’s merits action — divorce and property-division proceedings pending in Virginia — could not qualify as the “main action” the creditor had been ordered to commence in support of the attachment. The court disagreed: a foreign action can sustain a Korean provisional attachment, and the attachment court will not pre-screen whether the eventual foreign judgment will satisfy the recognition requirements. The functional equivalent of section 25 relief, in short, exists in Korea. It simply must be invoked — the Korean courthouse, not the foreign one, is where Korean assets are secured.
5. Practical implications for litigation and arbitration strategy
For cross-border litigants the lesson is now unambiguous: however effective at home, a foreign court’s attachment will not hold Korean assets. Creditors should map the counterparty’s Korean assets early and apply for Korean provisional attachment or provisional injunction in parallel with the foreign merits proceedings. The Korean remedies are well suited to the task: applications are typically decided swiftly and ex parte on a prima facie showing of the claim and of the need for preservation, usually conditioned on the applicant posting security, and — unlike a Mareva-type order operating in personam — a Korean provisional attachment fastens on the specific asset (real estate, receivables, shares, deposits) and binds third parties. The decided case also carries a warning for the opposite direction: a creditor that receives Korean distribution proceeds on the strength of a foreign interim order holds them precariously, and may be ordered to make restitution.
For parties in arbitration, the analysis converges on the same place — subject to one important check. Article 10 of the Arbitration Act permits a party to seek interim relief from the Korean courts before or during arbitral proceedings notwithstanding a valid arbitration agreement, and — by operation of Article 2(1) — that provision applies even where the seat of arbitration is outside Korea or not yet determined. But that access should not be taken for granted. In Decision 2022KaHap50245 dated 8 June 2023, the Cheongju District Court dismissed an application for a Korean injunction brought by a party to a Singapore-seated SIAC arbitration: Article 10 is a default rule that the parties may displace, and Rule 30.3 of the SIAC Rules 2016 — incorporated into the contract through the arbitration clause — was read by the court as making court-ordered interim relief impermissible once the tribunal is constituted, save in exceptional circumstances.
Nor are tribunal-ordered interim measures a substitute. They are court-enforceable only under Article 18-7 of the Arbitration Act, which — again by operation of Article 2(1) — reaches only tribunals seated in Korea; measures issued by a foreign-seated tribunal, including by an emergency arbitrator, have no enforcement route in Korea. The Cheongju court confirmed as much in the same decision: because the injunction sought was substantially identical to relief the SIAC emergency arbitrator had already granted, the court characterized the application as being, in substance, one to recognize and enforce a foreign tribunal’s interim measures — an application Korean courts have no power to entertain. The prevailing view is that such measures cannot be enforced as arbitral awards under the New York Convention either, precisely because they lack finality — the very feature on which Judgment 2025Da211405 turned.
Where Korean assets may need to be preserved, tribunal-ordered measures are therefore best treated as a complement to, not a substitute for, Korean court relief — and both drafting and timing matter: the seat determines whether Article 18-7 is available at all, the chosen institutional rules may make court relief subsidiary once the tribunal is in place, and a party that waits may find both doors closing at once.
The broader point is transactional. Asset preservation belongs in dispute planning from the outset, not as an afterthought once a dispute has escalated. When negotiating dispute resolution clauses in Korea-related transactions, parties should consider not only where their disputes will be resolved, but whether and how the chosen forum leaves timely access to Korean interim relief open when it is needed most — which, as the UAE creditor learned, may be earlier than expected.
