I spent nearly two decades as in-house counsel, advising multinational businesses entering or expanding in Korea, including five years as representative director of the Korean subsidiary of the German industrial group Robert Bosch. If there is one thing I learned from sitting on both the business and legal sides of that table, it is this: Korea rewards investors who take its regulatory system seriously, and it punishes, sometimes expensively, those who assume it works like the market they came from.
Korea remains one of Asia’s most attractive destinations for foreign direct investment, with deep technological infrastructure, a highly skilled workforce and a domestic market sophisticated enough to serve as a proving ground before global launch. However, commercial ambition alone rarely determines whether inbound investment succeeds here. In my experience, three legal areas deserve particular attention from the outset: labour and employment; taxation; and intellectual property.
Labour and employment

Korean labour law is protective of employees and enforced with real teeth, which surprises many multinational managers who assume the local subsidiary can operate the way headquarters does. Early in a market-entry project I once advised on, a manufacturer had classified a significant portion of its production-line workforce as contractor personnel supplied through a staffing arrangement, a structure that worked comfortably in its home market.
In Korea, that arrangement fell squarely within what is treated as illegal dispatch. Unwinding it after the fact, including the risk of mandatory direct-employment orders and potential personal liability for responsible executives under the applicable labour laws, cost far more than designing the workforce structure correctly at the outset would have.
Working-hour compliance, including the 52-hour weekly limit; statutory severance; and annual leave also require careful payroll and HR systems. Dismissals for performance or operational reasons face a genuinely high legal bar; “at-will” instincts imported from other jurisdictions do not translate well into the Korean employment environment.
What consistently worked for companies I advised was not more legal paperwork, but earlier involvement, bringing local HR and legal counsel into the workforce design conversation before headcount decisions were finalised rather than after a dispute had already begun.
Cross-border taxation substance
Korea has incorporated many of the OECD international tax principles, including those arising from the base erosion and profit shifting (BEPS) project, into its domestic tax framework. For a foreign-invested subsidiary, that alignment cuts both ways; it makes the rules predictable, but it also means the National Tax Service (NTS) has substantial experience in reviewing cross-border transactions involving multinational groups.
Transfer pricing is where this shows up most often in practice. Royalty payments, management service charges and intercompany goods pricing between a Korean subsidiary and its foreign parent are among the first things an NTS audit team will examine, and documentation prepared after the fact, however well reasoned, carries far less weight than documentation built contemporaneously with the transactions themselves.
I have seen boards in Germany or the US treat a Korean transfer-pricing query as a routine administrative matter, only to find that a poorly substantiated royalty structure led to a multi-year reassessment. Beyond transfer pricing, non-resident withholding tax, treaty relief and permanent establishment, exposure for liaison offices deserve attention at the structuring stage, not after capital has already moved.
On the positive side, the Foreign Investment Promotion Act continues to offer real tax credits and cash incentives for investment in strategic and high-technology sectors. However, capturing them requires legal, tax and finance teams to co-ordinate early, as eligibility criteria are specific and unforgiving of late applications.
Intellectual property protection
Korea operates a first-to-file system for trademarks and patents, and I have watched more than one foreign brand discover, only after committing to a local launch, that an identical or confusingly similar mark had already been registered by a local party, occasionally a former distributor. Filing before any public marketing activity or distributor discussion is inexpensive insurance; explaining after the fact why a mark should still belong to you is not.
Trade secrets and proprietary know-how sit in a similarly sharpened environment. Amendments to the Unfair Competition Prevention and Trade Secret Protection Act have expanded both the scope of protected information and the penalties available for misappropriation, including punitive damages for wilful infringement, which raises the stakes for companies bringing sensitive manufacturing or engineering know-how into Korea.
What actually holds up in a dispute, in my experience, is not the confidentiality clause in the employment contract alone, but whether the company can show it maintained real access controls and rigorous off-boarding procedures before an employee left.
For companies engaged in joint R&D with domestic partners or universities, foreground and background IP ownership needs to be defined in the contract before the collaboration begins; retrofitting an ownership position after a breakthrough has already been made is a negotiation no one wins comfortably.
A closing thought
None of this is meant to suggest that Korea is an unusually difficult place to invest. It is a demanding one, and those are not the same thing. The investors who have done well here, in my experience, shared a common habit: they treated legal and compliance functions as a source of early, commercially minded advice rather than a formality to be cleared just before signing. That habit costs little; not having it rarely does.
