Winning a dispute against a Korean counterparty is only half the job when its assets are in Korea. A foreign court judgment or arbitral award can’t reach a Korean bank account or building until a Korean court authorizes enforcement. How fast that happens, and what the other side can argue against it, depends mostly on whether you won in court or in arbitration, and, if arbitration, where it was seated.
Foreign Court Judgments: Recognition Plus an Enforcement Lawsuit
The Requirements for Recognition
Under the Civil Procedure Act, a final and conclusive foreign judgment is recognized in Korea if four requirements are met:
- the foreign court had international jurisdiction under principles Korean law accepts;
- the defendant was properly served in time to defend, or appeared anyway;
- recognition would not violate Korean public policy, judged by both content and procedure;
- reciprocity exists with the country that issued the judgment.
The Korean court doesn’t re-examine the merits.
Reciprocity: The Requirement That Decides Many Cases
Since the Supreme Court relaxed the test in 2004, it is enough that the two countries’ recognition requirements are substantially equivalent. An actual precedent of the other country enforcing a Korean judgment isn’t required. Korean courts have found reciprocity with the United States, applied state by state, and with Japan, Germany, and France, among others. Other countries are assessed case by case, and Korea is not party to any multilateral treaty on enforcing judgments. Confirm reciprocity before relying on a foreign judgment.
The Process: An Execution Judgment Lawsuit
Enforcement requires a separate lawsuit in the Korean district court where the debtor is based or holds assets. Uncontested cases can finish within months. A contested case that goes up to the Supreme Court takes much longer.
Damages Beyond Compensation
A 2014 provision lets Korean courts refuse damages that clearly conflict with Korean legal principles. But in March 2022 the Supreme Court enforced a Hawaii treble-damages judgment, because Korean law also allows treble damages in comparable areas such as fair trade. Enhanced damages are no longer automatically unenforceable.
Arbitral Awards: A Faster, Treaty-Backed Route
Enforcement by Decision, Not Judgment
Since the 2016 amendment to the Arbitration Act, a court enforces an award by decision instead of by full judgment. The applicant files the original or a certified copy of the award with a Korean translation. The court must hold a hearing or give the parties a chance to be heard, and its decision can be challenged by immediate appeal.
Foreign Awards: The New York Convention
Korea has applied the Convention since 1973 to commercial awards from other contracting states. A Korean court can refuse only on the Convention’s narrow grounds:
- an invalid arbitration agreement;
- improper notice or no fair chance to present the case;
- the tribunal going beyond what was submitted to it;
- an irregular tribunal composition or procedure;
- the award not yet being binding, or having been set aside at the seat;
- the dispute not being arbitrable;
- public policy, which Korean courts read narrowly.
Domestic Awards: Seated in Korea
An award from an arbitration seated in Korea has the same effect as a final court judgment. A party that wants it set aside must apply to a Korean court within three months of receiving the award.
Courts Have Been Consistently Supportive
Recent Supreme Court decisions upheld a defectively drafted arbitration agreement and allowed ICC awards to be enforced against non-signatories who took part without objecting.
KCAB vs. ICC: The Seat Matters More Than the Institution
The Question Behind the Question
Korean law sorts awards by where the arbitration was seated, not by which institution ran it. A KCAB or ICC arbitration seated in Seoul produces a domestic award. An ICC arbitration seated in Singapore or Paris produces a foreign award under the New York Convention.
What a Korean Seat Means for Enforcement in Korea
Korean courts handle both set-aside and enforcement, so the fight after the award stays in one court system. Korea is the only place the award can be annulled. Seoul-seated awards can still be enforced abroad under the New York Convention.
What a Foreign Seat Means for Enforcement in Korea
Set-aside happens at the seat, and the Korean court only decides whether to enforce. A pending set-aside application abroad can give the debtor grounds to adjourn Korean enforcement.
Choosing Between the Institutions
KCAB International is generally less expensive than the ICC. It introduced new domestic rules in March 2025 and plans an overhaul of its international rules. The ICC offers a global brand and review of draft awards by the ICC Court, which helps when an award may need enforcing in several countries. Both can be seated in Seoul. When the counterparty’s assets are mainly in Korea, a Seoul seat is a reasonable choice, not a concession.
From Enforcement Order to Actual Collection
Secure Assets Early
A provisional attachment can be sought before enforcement is granted, by showing the claim and a risk that assets will be moved. Courts decide quickly and without first hearing the debtor.
Finding and Seizing Assets
Once enforcement is granted, the creditor can attach bank deposits and receivables, obtain collection or transfer orders, and force sales of property or shares. If the debtor’s assets are unclear, the creditor can ask the court to order disclosure and to query financial institutions and public registries.
Practical Sequencing for Getting Paid in Korea
- Choose arbitration over foreign litigation when the assets are in Korea, unless reciprocity with the court’s country has been confirmed.
- Choose the seat deliberately, and choose the institution separately.
- Keep service and procedural records from the foreign proceeding.
- Check any damages beyond compensation against comparable Korean statutes.
- Apply for provisional attachment immediately.
- Prepare certified Korean translations in advance.
