Shadow Director Liability in South Korea

1. What Is a Shadow Director Under South Korean Law?

South Korean corporate law imposes director-level liability not only on formally registered directors, but also on persons who in substance direct or conduct the company’s affairs. The governing provision is Article 401-2(1) of the Commercial Act, which creates three categories of deemed directors.

The Three Categories Under Article 401-2(1)

Purpose of the Provision

The Supreme Court has explained that the provision is designed to “clarify and reinforce” the liability of those who, without being registered directors, direct or conduct a company’s affairs as if they were directors, ensuring they bear the same duty of care and duty of loyalty (Supreme Court Decision 2025Da216025, citing Supreme Court Decision 2001Da37071, January 10, 2003).

In practical terms, this prevents individuals from exercising effective control over a company while avoiding fiduciary responsibility by declining formal registration as a director.

2. What Titles Trigger Deemed-Director Status in South Korea?

The Commercial Act lists honorary chairman, chairman, president, vice president, executive managing director, managing director, and director as named examples, and adds a catch-all covering any title that “would reasonably be recognized as conferring authority to conduct the company’s business.” The test is therefore not confined to the listed titles.

Titles Found Sufficient in Supreme Court Decision 2025Da216025

In this case, Y1 used the titles “Division Head” (본부장) and “Vice President” (부사장), while Y2 used “Senior Director” (수석이사) and “Vice President” (부사장). Neither was a registered director of Company X. The court held that both fell within Article 401-2(1)(3).

Critically, the court did not rely on title alone. The following circumstances were considered together: (i) both were formally appointed as “chief officers in charge of restructuring and treasury” by the controlling shareholder; (ii) the board resolved that Y1 would perform supervisory functions equivalent to a joint representative director; and (iii) Y1 was delegated authority by the CEO to control the assets of a subsidiary.

Substance Over Form

This approach reflects a broader principle in Korean corporate litigation: courts look at what a person actually did, not merely what they were called. Titles such as “team leader” or “group head” could also attract liability if the holder in practice discharged responsibilities that belong to the board.

3. How Long Is the Statute of Limitations for These Claims in South Korea?

The limitation period is 10 years. The 3-year short-term limitation period that applies to ordinary tort claims under Article 766(1) of the Civil Act does not apply to claims under Article 401-2(1) of the Commercial Act.

Why 10 Years, Not 3?

The Supreme Court’s reasoning rests on the nature of the liability. Because Article 401-2(1) deems the relevant persons to be directors by operation of statute, their liability is not ordinary tort liability — it is liability that arises from the statutory deemed-director framework. Accordingly, the general 10-year limitation period under Article 162(1) of the Civil Act applies.

This was first established for registered director liability under Article 399 of the Commercial Act: “The liability of a director or auditor of a stock company for failure to perform their duties toward the company is not a general tort liability but a liability for breach of obligations arising from a mandate relationship; accordingly, the limitation period is 10 years, the same as for general claims.” (Supreme Court Decision 84Daka1954, June 25, 1985.) The same principle was then extended to deemed directors under Article 401-2(1) (Supreme Court Decisions 2020Da236848 and 2025Da216025).

Limitation Periods at a Glance

One practical note: where the same conduct also constitutes an ordinary tort, the 3-year short-term period may apply to any concurrent tort claim. The choice of legal basis for a claim therefore has direct implications for whether the claim is time-barred.

4. Does a Parent Company’s Board Owe a Duty to Supervise Subsidiaries in South Korea?

As a general rule, no. Under the principle of separate legal personality, a parent and its subsidiary are distinct legal entities. The Seoul High Court held that the mere fact of share ownership in a subsidiary — and the consequent effect on the parent’s asset valuation — does not, by itself, impose on the parent company’s directors a duty to manage or supervise the subsidiary’s operations (Seoul High Court Decision 2024Na2034079, July 9, 2025).

How Shareholder Losses Are Measured

A related point of practical importance: when a subsidiary suffers harm, the parent’s loss as a shareholder is not automatically equal to the funds transferred to or misappropriated from the subsidiary. The court explained that the parent’s recoverable loss should in principle be measured by the decline in the value of the subsidiary’s shares, and that separate evidence and argument on this point is required. Simply asserting that the amount transferred equals the loss will not suffice.

Implications for Multinational Groups Operating in South Korea

For foreign-invested companies with South Korean subsidiaries, this means that liability for misconduct at the subsidiary level will generally need to be established through the subsidiary’s own governance — focusing on who actually directed the subsidiary’s operations and in what capacity — rather than through the parent’s board. Where group-level executives hold formal positions in both the parent and subsidiary, the analysis shifts to their conduct in each capacity separately.

5. What Should Companies in South Korea Watch Out For?

The decisions discussed in this post carry several practical lessons for companies operating in South Korea, whether domestic or foreign-invested.

Be Careful with Titles Assigned to Non-Directors

Assigning titles such as vice president, executive director, or senior director to individuals who are not registered on the board creates a risk that those individuals will be treated as deemed directors — with full fiduciary obligations — under Article 401-2(1)(3). Legal review before finalizing title structures is advisable, particularly for titles used in dealings with third parties.

Internal Controls for Treasury and Investment Decisions

In the 2025Da216025 case, a core problem was the concentration of broad treasury and asset-control authority in individuals who were not registered directors. Large-scale transfers and investment decisions should be subject to board-level approval, and the delegation of authority to specific individuals should be clearly documented and limited in scope.

The 10-Year Limitation Period Works Both Ways

Companies that have suffered losses through the conduct of shadow directors have up to 10 years to bring claims — longer than many assume. Conversely, those who may face such claims cannot rely on a short-term limitation defense. Early legal assessment of potential claims, together with interim preservation measures where appropriate, is recommended for both sides.
