What Law Governs International Contracts Involving Korea?

Short Answer

Under the Korean Private International Act, a contract is governed by the law expressly or impliedly chosen by the parties (party autonomy). However, an implied choice is recognized only where it can be reasonably inferred from the contract terms and surrounding circumstances. Even where a foreign law is chosen, certain mandatory provisions of Korean law may still apply.

How Is Governing Law Determined?

In cross-border contracts involving Korea:

• The governing law is primarily determined by an express choice of law clause
• An implied choice may be recognized, but only where clearly supported by the contract and circumstances

Mere silence or failure to dispute governing law in litigation does not easily establish an implied choice.

---

What Happens If No Governing Law Is Specified?

If the parties do not specify a governing law:

• The contract is governed by the law of the country with the closest connection
• Korean law provides structured presumptions, including:
  • The law of the place where the party performing the characteristic obligation has its habitual residence or principal place of business
  • For contracts concerning real estate, the law of the location of the property

These rules reduce uncertainty but may still lead to disputes in practice.

---

Do Korean Mandatory Laws Still Apply?

Even where a foreign governing law is chosen:

• Mandatory provisions of Korean law may apply regardless of the chosen law
• This applies independently of the governing law clause
• Where all elements of a contract are closely connected to a single country, that country’s mandatory rules cannot be excluded

In certain areas (e.g., consumer or regulatory matters), additional protective rules may apply.

How Do Korean Courts Apply Foreign Law?

Where foreign law is designated as the governing law:

• Korean courts must investigate and apply foreign law ex officio
• Courts may require the parties to cooperate by providing materials or evidence regarding the content of foreign law

If the content of foreign law cannot be sufficiently established, practical difficulties may arise in litigation.

How Does Jurisdiction Affect Governing Law?

The jurisdiction clause determines where disputes are resolved and may affect how governing law is applied.

• Jurisdiction agreements are generally recognized if properly made in writing
• Agreements designating a foreign court may lead Korean courts to decline jurisdiction, subject to exceptions

Governing law and jurisdiction should be considered together in cross-border contracts.

---

Do International Conventions Apply?

For certain transactions, international conventions may apply with priority.

• In international sales of goods, treaties such as the CISG may govern the contract
• The chosen governing law applies only to matters not covered by the applicable convention

This may significantly affect interpretation and enforcement.

---

What Are the Practical Risks?

For foreign individuals and companies entering into contracts involving Korea, key risks include:

• Uncertainty where governing law is not clearly specified
• Limited recognition of implied choice of law
• Application of mandatory Korean law regardless of choice
• Difficulties in proving and applying foreign law
• Misalignment between jurisdiction, governing law, and enforcement strategy

These factors may materially affect both interpretation and enforcement.

Conclusion

The governing law of international contracts involving Korea is primarily determined by party autonomy, subject to important limitations.

Careful drafting of governing law, jurisdiction, and awareness of mandatory Korean law and applicable international conventions is essential in cross-border transactions involving Korea.
