Crypto Exchange as Third-Party Garnishee in Korea

When a fraudster moves stolen funds into a Korean centralized exchange, foreign counsel often face the same question: how do we freeze and recover assets sitting in a wallet we cannot touch? Korean civil execution provides a workable answer. The exchange itself can be treated as a third-party garnishee. By attaching the debtor’s claim against the exchange, foreign claimants can immobilize crypto holdings on a Korean platform and convert them into recoverable value through Korean court process. This guide explains how the crypto exchange garnishee mechanism works in Korea, where it diverges from the UK and US equivalents foreign counsel are used to, and what to instruct local counsel to do at each stage.

Why Korean Crypto Exchanges Are the Critical Choke Point

Korea is unusual among major jurisdictions in how tightly its centralized crypto exchanges are regulated. Two statutes do most of the heavy lifting. The Act on Reporting and Use of Specific Financial Transaction Information (“Specific Financial Information Act,” commonly the “FRA”) requires every virtual asset service provider to register with the Korea Financial Intelligence Unit and to operate through real-name banking accounts at one of a small group of designated Korean banks. The Virtual Asset User Protection Act (VAUPA, Act No. 19563, in force since 19 July 2024) layers on customer asset segregation, insurance, and transaction recordkeeping obligations.

The practical consequence for asset recovery is significant. Every customer of a Korean exchange has been KYC’d against a Korean resident registration number or foreign registration number and tied to a Korean bank account. The five major exchanges — Upbit, Bithumb, Coinone, Korbit, and Gopax — concentrate the overwhelming majority of domestic spot volume. If illicit proceeds have been routed through Korean fiat off-ramps or sold for KRW, the trail almost always passes through one of these five.

For foreign counsel, this means Korean exchanges are simultaneously a chokepoint and a counterparty that can be served. They are not anonymous protocols; they are licensed entities with a Korean address for service, mandatory recordkeeping under VAUPA, and KRW reserves that Korean courts can reach.

Civil Execution Framework for Crypto Assets (Article 251 et seq.)

Korean civil execution treats the relationship between a customer and a centralized exchange as a contractual claim: the customer holds a right against the exchange to demand delivery of, or accounting for, a specified quantity of crypto assets. That right — variously described as a return claim (반환청구권) or withdrawal claim (출급청구권) — is the asset the creditor attaches. The exchange is the third-party debtor (제3채무자), and the customer is the judgment debtor.

Two articles of the Civil Execution Act are central. Article 223 opens compulsory execution against a debtor’s monetary claims and other claims for the transfer or delivery of property held by a third party — execution begins with a court attachment order. Article 251 extends the same machinery to “other property rights” not covered by the specific money-claim provisions. Because a customer’s claim against a Korean exchange is generally treated as a property right rather than a pure money claim (until it is converted to KRW), Article 251 is the operative provision for crypto holdings. The Supreme Court has long recognized crypto as “property with economic value” — see Supreme Court Decision 2018Do3619 (30 May 2018) — and Korean lower courts have applied the Article 251 framework to allow attachment of crypto withdrawal claims against domestic exchanges in practice.

For foreign counsel, the closest equivalents are familiar but not identical:

• England and Wales: a third-party debt order under CPR Part 72 reaches money due to the judgment debtor from a third party. Korea’s Article 251 process reaches the underlying property right itself, not just the money equivalent.
• United States: a writ of garnishment under state procedure (e.g., New York CPLR Article 52) is conceptually closest. The functional steps are similar; the documentary requirements and the timing windows differ.
• Civil law jurisdictions: practitioners familiar with German Pfändung of “anderes Vermögensrecht” under ZPO §857 will recognise the structure almost line for line.

The point is not that Korea is exotic. The point is that Korean counsel must translate the foreign claim into the right Korean cause of action and the right execution title before the exchange will treat the order as binding.

Pre-Judgment Attachment (가압류) of Crypto Holdings

In most cross-border fraud cases, foreign counsel cannot wait for a judgment before acting. By the time a UK or US claim is issued, the assets may already be moving. Korea’s provisional attachment regime — gaapryu (가압류) — is the tool of first resort. A Korean court can issue a provisional attachment order on an ex parte basis, normally within one to two weeks of filing, when the applicant shows (i) a prima facie case on the underlying claim (피보전권리 소명) and (ii) a need to preserve (보전의 필요성), typically the risk that the debtor will dissipate the asset.

For crypto holdings, the application targets the debtor’s withdrawal claim against the named exchange. The pleading must identify the exchange, the debtor’s account (member ID, registered name, and to the extent known the email or phone number used to register), and the assets to be preserved (specific coins and approximate quantities, or “all virtual assets held”). The court typically requires the applicant to post security — usually a cash deposit or a surety bond from a Korean insurer — in an amount the court determines on a case-by-case basis. Foreign claimants without a Korean bank account often satisfy this through a surety bond arranged by local counsel.

Once the order is issued and served on the exchange, the exchange is prohibited from honouring withdrawal or trading instructions from the customer with respect to the attached assets. In our practice the major Korean exchanges treat properly served attachment orders as binding from the moment of service and freeze the relevant balances pending resolution. For foreign claimants pursuing parallel criminal complaints for fraud or breach of trust under Korean criminal law, the provisional attachment often runs in parallel with the criminal investigation, with the criminal proceedings producing evidence that strengthens the civil case.

Garnishee Order and Asset Realization (추심·전부명령)

Provisional attachment preserves the position; it does not transfer value. To convert frozen exchange holdings into recoverable funds, the claimant needs an execution title (집행권원) — typically a Korean judgment on the merits, or a Korean enforcement judgment recognizing a foreign judgment (discussed below). Once that title is in hand, the claimant applies for a garnishee order (추심명령) or a transfer order (전부명령) over the now-attached withdrawal claim.

The mechanics under Article 229 of the Civil Execution Act are written for money claims, but Korean courts apply the same logic by analogy to property right claims under Article 251. A garnishee order empowers the creditor to collect directly from the exchange; a transfer order assigns the underlying claim to the creditor in satisfaction of the judgment debt. Which one is preferable depends on the case: a transfer order extinguishes the debt up to the value of the assigned claim and shifts insolvency risk to the creditor, while a garnishee order leaves the creditor with continuing rights against the debtor if collection falls short.

A recurring practical question is whether the exchange delivers crypto in kind or sells it on the platform and remits KRW. Korean exchanges generally prefer to liquidate attached holdings to KRW under controlled execution and remit fiat to the creditor’s account, both because it sidesteps the customer-asset segregation rules of VAUPA and because foreign claimants typically prefer fiat. Where the creditor specifically wants delivery in kind — for example, where a particular token is the subject of the underlying dispute — this needs to be negotiated and ordered up front; it is not the default.

For foreign creditors, the final step is moving KRW out of Korea. Outbound wire transfers above the standard reporting threshold trigger Foreign Exchange Transactions Act notifications, but legitimate court-ordered recovery proceeds are not blocked — they require documentation that local counsel routinely prepares.

Practical Considerations for Foreign Counsel

Instruct Korean counsel early. The provisional attachment timeline can be very short — sometimes a matter of days from the point of decision — and foreign counsel typically need 24 to 48 hours of front-loaded work with Korean counsel to assemble the identification details the court will require. Waiting until a foreign judgment exists is usually too late; by then the assets have often moved off-exchange.

Plan for enforcement of any foreign judgment. If the underlying claim is being litigated outside Korea, the foreign judgment will need recognition before it can ground a Korean garnishee order. Recognition is governed by Article 217 of the Civil Procedure Act, and execution requires an enforcement judgment under Article 26 of the Civil Execution Act. Korean courts apply the four classical conditions — jurisdiction of the rendering court, proper service, public policy compatibility (with the public policy bar tightened by Article 217-2 for punitive damages), and reciprocity. UK and US commercial judgments are routinely recognized on these grounds; building a clean record with proper service on the Korean-domiciled defendant from the outset of foreign proceedings is the single most important step a foreign counsel can take to avoid recognition friction later.

Budget realistically. Provisional attachment fees and court security typically run in the low thousands of US dollars equivalent. The substantive proceedings — recognition (if applicable), the garnishee order, and any contested intervention by the debtor — typically resolve in six to eighteen months depending on complexity and contestation. Parallel criminal proceedings, where available, can accelerate cooperation from the exchange and from the debtor.

Coordinate with the exchange. The five major Korean exchanges have legal departments that handle court orders routinely. Properly served Korean court orders are honoured; foreign-language orders without a Korean translation, or orders served at the wrong address, are not. Always have Korean counsel handle service.
