Can a Contract Be Terminated for Breach in Korea?

Short Answer

Yes. A contract can generally be terminated for breach in Korea if one party fails to perform an important contractual obligation and the legal or contractual requirements for termination are satisfied.

However, contract termination is not automatic simply because the other party breached the contract. Under Korean law, the party seeking to end the contract usually needs to consider whether the breach is serious enough, whether a notice of breach or reasonable cure period is required, and whether the contract allows immediate termination.

In Korean legal practice, the word “termination” may also require careful analysis. Depending on the type of contract, Korean law may distinguish between rescission, which may have retroactive effect, and termination, which generally operates prospectively for continuing contractual relationships.

Because an invalid or premature termination may expose the terminating party to liability, foreign companies doing business with Korean counterparties should carefully review the contract, evidence, termination clause, and applicable Korean law before sending a termination notice.

When Can a Contract Be Terminated for Breach in Korea?

Under Korean law, a party may generally end a contract where the other party fails to perform an important contractual obligation and the breach justifies ending the contractual relationship.

Common examples include failure to deliver goods, failure to pay, serious delay in performance, delivery of materially defective products, breach of confidentiality, breach of exclusivity, unauthorized use of intellectual property, or refusal to perform key contractual duties.

That said, not every breach justifies termination. If the breach is minor, technical, or easily curable, immediate termination may be challenged as excessive or premature. The key question is usually whether the breach is serious enough to defeat the purpose of the contract or make continued performance unreasonable.

For foreign companies, this issue often arises in supply agreements, distribution agreements, manufacturing agreements, OEM or ODM contracts, agency agreements, and other cross-border commercial contracts involving Korea.

Is Prior Notice Required Before Termination?

In many cases, yes.

Where performance is still possible, the non-breaching party may need to send a notice demanding performance and provide a reasonable opportunity to cure before terminating the contract. This is especially important where the contract itself provides a specific cure period.

For example, if a Korean supplier is late in delivering products, the buyer may not always be able to terminate immediately. Unless the contract clearly allows immediate termination or the delay destroys the essential purpose of the transaction, the safer approach is often to send a written notice requiring delivery within a specified period.

Important evidence may include:

• the written contract and termination clause;
• purchase orders, invoices, and delivery schedules;
• emails, messages, and prior warnings;
• inspection reports or non-performance records; and
• any written cure demand or termination notice.

A termination notice may sometimes function as a demand for performance, but the timing and wording are important. If the required notice or reasonable cure period is not properly given, the termination may later be challenged.

---

When Is Immediate Termination Possible?

Immediate termination may be possible, but it should be treated as an exception rather than the general rule.

Immediate termination may be considered where performance has become impossible, the contract expressly permits immediate termination, the transaction is time-sensitive and the delay defeats the purpose of the contract, or the counterparty has clearly and finally refused to perform.

In particular, a refusal to perform should be assessed carefully. Under Korean legal principles, an alleged refusal to perform must generally be clear and final before it can justify termination without further demand. Ambiguous delay, negotiation, or disagreement over contract terms may not be enough.

In commercial practice, immediate termination may become an issue in cases involving repeated non-delivery, serious product defects, unauthorized use of drawings or molds, disclosure of confidential information, fraudulent conduct, or complete loss of trust in a continuing supply or manufacturing relationship.

Even in these cases, the terminating party should clearly document the grounds for termination and avoid vague or emotional termination language.

What Is the Difference Between Rescission and Termination in Korea?

In English contracts, the word termination is often used broadly. However, under Korean law, it may be necessary to distinguish between rescission and termination.

In general, rescission is more commonly relevant to one-time transactions such as sale and purchase contracts. It may have retroactive effect and can raise issues such as return of payments, return of goods, and restoration of the parties to their original positions.

By contrast, termination is more commonly relevant to continuing contractual relationships, such as distribution, agency, lease, license, franchise, long-term supply, or manufacturing relationships. Termination generally operates prospectively, meaning it ends the contract going forward rather than completely unwinding past performance.

This distinction can affect important issues such as:

• whether payments or goods must be returned;
• whether past performance remains valid;
• whether continuing obligations survive;
• whether damages may still be claimed; and
• how the termination notice should be drafted.

For foreign companies, this distinction is important because the English word “termination” may not always capture the precise Korean law effect of ending a contract.

Why Does the Termination Clause Matter?

The termination clause is often one of the most important provisions in a Korean contract dispute.

A well-drafted termination clause should address when termination is allowed, whether prior notice is required, how long the cure period is, whether immediate termination is available, what happens to unpaid amounts, and whether damages may still be claimed after termination.

For example, the contract may provide that a party may terminate if the other party fails to cure a material breach within 10, 15, or 30 days after written notice. In other cases, the contract may allow immediate termination for specific serious events, such as insolvency, unauthorized disclosure of confidential information, infringement of intellectual property, or repeated failure to deliver.

For foreign companies, this is particularly important because termination rights under Korean law may not operate in the same way as under their home jurisdiction. A broad assumption that “breach equals termination” can be risky.

If the contract is governed by Korean law or enforcement is expected in Korea, the termination clause should be reviewed from a Korean law perspective before action is taken.

Does the Terminating Party Need to Perform Its Own Obligations?

Sometimes, yes.

In many Korean contract disputes, especially in sale, supply, or manufacturing contracts, the parties’ obligations may be connected. For example, one party’s obligation to deliver goods and the other party’s obligation to pay may be in a concurrent or mutually dependent relationship.

In that situation, a party seeking to terminate based on the other party’s non-performance may need to consider whether it has performed, offered to perform, or was legally excused from performing its own obligations.

This issue can become important where the supplier argues that it did not deliver because the buyer failed to pay, failed to provide specifications, failed to approve samples, failed to provide materials, or changed the order.

Accordingly, before terminating a Korean contract, the terminating party should review not only the counterparty’s breach, but also whether its own contractual obligations were properly performed or tendered.

---

Can Damages Be Claimed After Termination?

Yes. Termination and damages are separate issues.

If a contract is validly terminated due to breach, the non-breaching party may still claim damages for breach of contract if the legal requirements are satisfied.

In a supply or manufacturing dispute, damages may include unpaid amounts, additional procurement costs, losses caused by delay, storage or logistics costs, costs of substitute performance, losses caused by defective products, or other provable losses.

However, damages must be proven. The claimant generally needs to show:

• the contractual breach;
• the actual loss;
• the causal connection between the breach and the loss; and
• the amount of damages with supporting evidence.

In practice, damage claims should be supported by objective records such as contracts, invoices, purchase orders, delivery schedules, inspection reports, replacement purchase records, accounting materials, and written communications.

---

What Are the Risks of Wrongful Termination?

Wrongful termination can create significant legal risk.

If the termination is held invalid, the contract may remain in force. In that situation, if the terminating party refuses to continue performance, that refusal may itself be treated as non-performance and may expose the terminating party to damages or counterclaims.

This risk is especially important in long-term supply agreements, distribution agreements, manufacturing agreements, agency agreements, licensing agreements, and other continuing business relationships.

Before terminating, a company should consider whether a cure notice, reservation of rights letter, suspension of performance, negotiation, or settlement discussion may be more appropriate as an initial step.

In practice, termination should be approached not only as a legal decision, but also as a litigation and enforcement strategy.

Practical Considerations for Foreign Companies

Before terminating a Korean contract for breach, foreign companies should carefully check the governing law, termination clause, notice requirements, seriousness of the breach, available evidence, possible counterclaims, and whether enforcement may be needed in Korea.

They should also consider practical issues such as unpaid invoices, remaining inventory, return of goods, return of molds or tools, protection of drawings and technical data, confidentiality obligations, and continued use of intellectual property after termination.

In cross-border transactions, the company should also review whether disputes must be handled through Korean courts, foreign courts, or arbitration, and whether the counterparty has assets in Korea that can be enforced against.

In many Korean contract disputes, the key issue is not only whether termination is legally possible, but whether the terminating party can later prove that termination was justified.

---

Conclusion

A contract may be terminated for breach in Korea if the breach is serious enough and the required legal or contractual procedures are followed.

However, termination should not be treated as automatic. The terminating party should carefully review the contract, provide a notice of breach or reasonable cure period where necessary, preserve evidence, and clearly identify the legal and factual grounds for termination.

For foreign companies doing business with Korean counterparties, a careful termination strategy can help reduce the risk of counterclaims and strengthen the company’s position in any later negotiation, litigation, arbitration, or enforcement proceeding in Korea.
