A creditor with a foreign judgment against a Korean company often assumes the hard part is over. In Korea, it may not be. The judgment has no effect on Korean assets until a Korean court confirms it meets the four requirements of Article 217 of the Civil Procedure Act. The court won’t revisit the merits. It will look closely at jurisdiction, service, public policy, and reciprocity. Most failures trace back to decisions made at the start of the foreign case, so the time to think about Article 217 is before filing abroad.
How Article 217 Works
What Qualifies for Recognition
Article 217 covers a final and conclusive foreign judgment, or a decision with the same effect. Interim or provisional orders generally don’t qualify. Default judgments can qualify once final, but they get the closest scrutiny on service.
The Four Requirements
- The foreign court had international jurisdiction under Korean law or treaties.
- The defendant was lawfully served, in time to defend and not by public notice or a similar method, or appeared in the case anyway.
- Recognition would not violate Korean public order or good morals, judged by both content and procedure.
- Reciprocity exists with the issuing country.
The court checks all four on its own initiative, even if the defendant doesn’t raise them.
Recognition Is Automatic, but Enforcement Is Not
In June 2025, the Supreme Court confirmed that a qualifying foreign judgment is binding in Korea without a separate recognition proceeding, so the creditor can’t simply refile the same claim in Korea. To seize assets, though, the creditor still needs a separate lawsuit for an execution judgment.
Requirement 1: International Jurisdiction
Judged From Korea’s Point of View
The Korean court asks whether it would have accepted jurisdiction in the mirror-image situation. Thin connections that the foreign court’s own rules happen to allow may fail.
The 2022 Codification
The revised Private International Law Act now sets detailed jurisdiction rules: the defendant’s domicile or principal office, business directed at the forum, place of performance, place of the tort, consumer and employment contracts, agreed jurisdiction, and jurisdiction by appearance.
Jurisdiction Clauses Cut Both Ways
A clause choosing the foreign court is the creditor’s strongest fact. A clause giving exclusive jurisdiction to Korea or a third country can defeat recognition. A defendant who argued the merits abroad without contesting jurisdiction will find it hard to challenge jurisdiction later.
Requirement 2: Lawful and Timely Service
The Most Litigated Requirement
Whether service was lawful is judged under the foreign court’s own law and the treaties it applies. In 2010 the Supreme Court refused a Washington State default judgment because the Korean defendant got 20 days to respond instead of the 60 days Washington law required for out-of-state defendants.
Public Notice Service Doesn’t Count
Service by publication or courthouse posting is expressly excluded, even when the foreign court’s law allows it.
Substituted Service and Service Into Korea
Delivery to a family member or employee has been accepted when it was lawful under the foreign court’s law. For a defendant in Korea, service through the Hague Service Convention’s Central Authority with a Korean translation leaves the cleanest record. Direct mail without a translation invites a challenge.
Appearance Cures the Problem
If the defendant appeared and defended, the service requirement is met. Appearing only to contest jurisdiction is a closer question.
Requirement 3: Public Policy
Content and Procedure
Courts consider the judgment’s connection to Korea and the actual effect of recognizing it. The bar is high: a different result under Korean law isn’t enough.
Damages Beyond Compensation
Since 2014, Article 217-2 lets courts refuse damages that clearly conflict with Korean law. In March 2022, however, the Supreme Court enforced a Hawaii treble-damages judgment because Korean law allows treble damages for comparable conduct.
Fraud and Conflicting Judgments
A claim that the judgment was obtained by fraud generally isn’t enough on its own. Courts have accepted it only where the defendant couldn’t have raised the fraud abroad and there is clear proof. A foreign judgment that conflicts with an existing Korean judgment can also be refused.
Requirement 4: Reciprocity
The Modern Standard
Since 2004, it is enough that the two countries’ recognition requirements are substantially equivalent. No treaty and no actual enforcement precedent is needed. In June 2025, the Supreme Court found reciprocity with Malaysia on this basis.
Where Reciprocity Is Established
Korean courts have found reciprocity with the United States (assessed state by state), Japan, Germany, and France, among others. Other forums should be analyzed before filing.
Pre-Litigation Screening: What a Creditor Should Check Before Suing Abroad
- Locate the assets first. If they’re mainly in Korea, test every decision in the foreign case against Article 217.
- Test the forum’s jurisdiction from a Korean perspective.
- Serve through the Hague Central Authority with a Korean translation, allow the full response period, keep the service record, and never rely on publication.
- Confirm reciprocity for the specific forum.
- Frame damages with Article 217-2 in mind.
- Prepare translations and a provisional attachment application in advance.
- Consider arbitration instead while the contract is still being negotiated.
