They Love the Deal. So Why Won’t They Sign?
The Signature Paradox: Why Korean Partners Hesitate, and What Korean Law Actually Says
Bridging Culture Worldwide | Client Advisory
Over more than twenty years of working with Korean companies, I keep running into the same paradox. A Korean partner is enthusiastic, has invested months in the relationship, and clearly sees the mutual benefit. Then the agreed documents arrive to be signed, and they hesitate, or simply do not sign.
Western teams read this as cold feet. It rarely is. The reluctance is usually not doubt about the deal. It is a reasonable response to how Korean law actually works.
Korea is a civil-law system with no consideration doctrine. Under the Korean Civil Act, a properly formed agreement is binding without the exchange of value that common-law systems require. The practical implication, which most U.S. lawyers miss: a document labeled “non-binding,” an MOU or a letter of intent, may already be an enforceable contract under Korean law, regardless of what either side intended. In Korea, the signature does the binding, not the consideration.
So a signed MOU carries weight on three layers at once. Legally, it may already be a contract. Culturally, it reflects a leadership-level decision with organizational commitment behind it, and walking it back signals that your word cannot be trusted. Reputationally, Korea’s senior business community is small and interconnected, and a company that treats MOUs as disposable will find future partners more guarded.
The mirror image is also true: the Western “immutable contract” assumption is partly wrong in Korea. There, signing formalizes the partnership, and the relationship is expected to keep adjusting the terms as conditions change. Korean law reinforces this. Good faith is not just a canon of interpretation; under Article 2 of the Civil Act it is an enforceable obligation. Two features compound the effect. Under the Standard Terms Regulation Act, boilerplate is not automatically enforceable even when signed, and surprising or onerous clauses must be specifically flagged or risk being void. And Korean mandatory rules, including PIPA, the Korea Fair Trade Act, and the National Core Technology framework, can override your choice of law where Korean operations, data, or technology are involved. The KFTA in particular can reach conduct that originates abroad.
BCW Take
After the ink dries, terms can be reopened. Staff rotate onto the project, arrive unfamiliar with prior compromises, and may press for changes. Korean management is highly hierarchical, the people who negotiate often cannot sign, and approvals can climb to quarterly board meetings. Even returning the executed copies can take weeks.
The takeaway is not to abandon documentation. It is to stop treating it as a friction-free formality. Build the relationship and the paperwork in parallel. Get Korean counsel to confirm whether your “preliminary” documents are already enforceable. Flag your boilerplate proactively rather than waiting for it to be challenged. Identify the Korean mandatory rules your deal engages at the drafting stage, not after a dispute. And budget for the hierarchy and board cycles that govern Korean sign-off.
The patience this requires is not a cost of doing business in Korea. It is the business of doing business in Korea.
