Signing an NDA with a Korean Company: 5 Clauses to Read Twice

An NDA you sign with a Korean company is a binding contract under Korean law — the real question is how much it actually protects. In practice, that is decided by five clauses: what counts as confidential, whether the duty runs both ways, what the information may be used for, how long the duty survives, and what happens on a breach. Here is how to read each one, from the perspective of a foreign company dealing with a Korean counterparty.

I'm Jaewon Lee, an attorney and patent attorney in Seoul, advising foreign companies on Korean contracts and IP in English. The NDA is usually the first document a Korean partner sends you — before the deal terms, sometimes before the first real meeting. Because it arrives early and looks short, it tends to get signed fast. It shouldn't: if the relationship later breaks down, this is the document both sides reach for first.

Does an NDA Actually Work in Korea?

Yes — and it does double duty. As a contract, it is enforceable like any other agreement governed by Korean law. On top of that, Korea protects trade secrets by statute: under the Unfair Competition Prevention and Trade Secret Protection Act, Article 2, information qualifies as a trade secret when it is not publicly known, has independent economic value, and has been kept secret through management efforts. The Act gives the holder remedies against misappropriation, including court injunctions, damages and, in serious cases, criminal sanctions. Notice the third element: kept secret. A signed NDA is strong evidence that you managed the information as a secret — but only if your actual practice matches it. If the same files circulate internally without access control, the statutory protection weakens no matter what the contract says. Sign the NDA, and run your information handling as if the definition clause were being tested in court.

What Counts as Confidential — and Whose Secrets Are Covered?

Now to the clauses. First, the definition. Korean-drafted NDAs often define confidential information very broadly — something close to "all information disclosed in connection with the transaction." Whether that helps or hurts you depends entirely on which direction the information mainly flows. If you are the one opening your technology or pricing to the Korean side, breadth is your friend, and you should also make sure disclosures made orally or in demonstrations are captured, not just documents stamped "confidential." If you are mainly the recipient — say, evaluating a Korean manufacturer's process data — an unlimited definition quietly turns every email from them into a compliance burden, and you should push for specificity.

Second, the direction. Check whether the draft is one-way or mutual. First drafts tend to protect the drafter, and it is common to receive a one-way NDA even where both sides will clearly be exchanging materials. Asking a Korean counterparty to convert it to a mutual NDA is a routine, unremarkable request — refusal with no explanation tells you something worth knowing before the deal goes further.

How Can Your Information Be Used — and for How Long?

Third, the purpose clause. A well-drafted NDA limits use of the information to evaluating or performing the specific transaction, and forbids everything else. Without that limit, a counterparty that walks away from the deal may treat what it learned — your cost structure, your specifications, your roadmap — as general market knowledge. Read the standard exceptions (information already known, publicly available, or independently developed) with the same care: they are legitimate, but drafted too widely they can hollow out the purpose limit from the inside.

Fourth, duration. Distinguish the term of the NDA itself from the survival of the confidentiality duty. The negotiation may end in three months; the duty to keep your information confidential should run for a defined period beyond it, matched to how long the information stays commercially sensitive. Check also what must happen when the discussions end — return or destruction of materials, and on whose certification. If you are the recipient, resist an indefinite survival period; it creates a compliance obligation with no end date.

What Happens If It's Breached — and Where Would You Sue?

Fifth, enforcement — for a cross-border NDA, the clause that deserves the second reading most. Korean NDAs frequently include a liquidated damages provision: a pre-agreed sum payable on breach, which spares the injured party from proving the exact loss (often the hardest part of a confidentiality dispute). Weigh the figure against the size of the deal, in both directions — as discloser it is your safety net, as recipient it is your exposure.

Then look at governing law and forum. If the draft says Korean law and a Korean court, that is not a trap; for a dispute with a Korean company whose assets and people are in Korea, a Korean judgment is often the most enforceable outcome available. What you should question is a forum that is inconvenient for both sides, or one that leaves you litigating in a third country neither party has assets in. And if the NDA exists in Korean and English versions, find the clause that says which language prevails — in a dispute, that one sentence can matter more than any other. If only a Korean version exists, have it reviewed before signing rather than relying on machine translation for a document you may one day need to enforce.

The Checklist, in One Paragraph

Definition — broad or specific, and does it fit your direction of disclosure. Mutuality — one-way drafts deserve a conversation. Purpose — use limited to this transaction, exceptions kept honest. Duration — a defined survival period plus return or destruction. Enforcement — a balanced liquidated damages figure, a forum you can realistically use, and a controlling language you have actually read. One closing caution: this is a map of the usual terrain, not of your deal. Mandatory rules of Korean law, the statutory requirements for trade secret protection, and the specifics of your industry can all shift how these clauses play out, so have the draft in front of you reviewed before you sign it.
