Why Korean Courts Interpret Stock-for-Filial-Piety Promises So Strictly

The question we hear most often from parents in consultation rooms is this: I gave them so much. If my child does not take care of me, should I not be able to get it back? Contrary to the layperson intuition, courts interpret the conditions for rescinding a gift contract very strictly. The lawsuit by Yoon Dong-han, chairman of Kolmar Korea, against his eldest son and vice chairman Yoon Sang-hyun of Kolmar Holdings for the return of stock has put this issue back in the spotlight. This article compares conditional gifts (filial piety contracts) and trusts, organizing how to structure intergenerational asset transfers to reduce disputes.
What the Kolmar Korea Case Shows Us
On May 30, 2025, Chairman Yoon Dong-han filed suit at the Seoul Central District Court against his eldest son, Vice Chairman Yoon Sang-hyun of Kolmar Holdings, seeking the return of shares. It came less than five years after the vice chairman became the largest shareholder in December 2019 and management succession was completed. With sibling conflict deepening, the chairman seeks to recover 4.6 million shares (after free bonus issuance).
The core issues of this case are: what conditions accompanied the chairman gift of shares to the vice chairman, were the conditions express or implied, and if express, how should it be interpreted whether they were fulfilled or unfulfilled?
Why Inter Vivos Gifts Have Increased
Before getting to the central issue, it helps to organize why inter vivos gifts have become popular. There are clear reasons more people now actively use lifetime gifts.
- Tax benefits: For lineal descendants, no gift tax is imposed on amounts up to KRW 50 million (KRW 20 million for minor children) every 10 years.
- Reflection of asset appreciation: When assets tend to appreciate over time, the valuation at gift is likely lower than the valuation at inheritance.
- Reduction in inheritance tax base: Inheritance tax includes only gifts within 10 years before death in the estate. Pre-emptive gifts reduce the inheritance tax base, and given the progressive rate, the applicable rate itself drops.
For these reasons, gifts to grandchildren and not just children have also increased. But gifts simultaneously become the starting point of disputes.
Two Streams of Post-Gift Disputes
Disputes around gifts generally arise in two streams.
The first stream is disputes in ordinary families. Parents expect their children to support their later years, gift assets accordingly, and after the gift the child attitude changes, making the parents retirement difficult. Because these are intra-family transactions, written agreements are rare, and at the dispute stage proving an oral promise is difficult.
The second stream is disputes in corporate succession. A major shareholder gifts company shares to a child expecting stable management of the company, but the successor fails to fulfill that duty or pursues management directions different from what the chairman expected. The Kolmar Korea case falls here. The pre-successor (chairman) then considers whether shares can be recovered against the successor (child) for breach of the gift conditions.
The Big Picture: Lifetime Wealth Transfer and Post-Mortem Wealth Transfer
To understand gift disputes, it helps to organize the big picture of wealth transfer.
- Post-mortem transfer: Will-substitute trusts, gifts in contemplation of death, notarized wills, regular wills, and statutory inheritance under the Civil Code when no will exists.
- Lifetime transfer: Gifts and trusts.
The distinguishing feature of will-substitute trusts is consistent design from lifetime rights through post-mortem transfer. Other instruments focus on post-mortem transfer, whereas a will-substitute trust can also designate who enjoys what rights during life. Ordinary trusts remain underutilized in Korea due to absent tax benefits and fee costs, but in the United States, trusts conditioned on a child college enrollment, marriage, or grandchild birth are commonly designed.
Why a Completed Gift Is So Difficult to Reverse
A question we often hear in consultations is: I regret the gift; can I get it back? In principle, no. A gift transfers ownership itself. At the moment of gifting, the donor loses all rights as owner. To recover the property, the gift contract must be lawfully rescinded.
This is where conditional gifts enter, and what is commonly called a filial piety contract is one example. The structure conditions the gift on the child filial duty toward the parent.
How Specific Must Rescission Conditions Be?
There is a clear reason why courts interpret conditional gifts strictly. Restoring ownership materially alters property relations, so where the condition is not clear, it cannot easily be recognized: this is the judiciary basic stance.
If a rescission clause is expressly recorded in the contract, recognition is at least possible. But finding an implied duty is extremely difficult. To impose a duty on the donee, the donor must therefore set out specific, clear rescission conditions in the contract.
| Form of Condition | Likelihood of Recognition | Note |
|---|---|---|
| Implied duty of filial piety | Very low | Read as the natural affection of family ties; hard to establish |
| Abstract filial clause (be filial) | Low | Heavy dispute over the meaning of filial piety |
| Abstract support clause (take care of parents well) | Low | Vague criteria for evaluation |
| Concrete support clause (monthly support of KRW X, weekly visits, etc.) | Relatively high | Performance and non-performance can be objectively verified |
| Concrete management clause (maintaining a specific business line, consent for certain decisions, etc.) | Case-by-case | Often used in gifts of company shares |
In consultations, the layperson intuition (since I gave it on the obvious premise of being cared for, I can take it back if they do not) frequently runs head-on against the court reasoning. Family relations actually demand more precise drafting.
One More Point: Conditions Must Not Violate Public Policy
Another point to remember when setting rescission conditions: they must not violate good morals or public order. Unlawful or socially unacceptable conditions have no effect, even if written into the contract.
When designing a filial piety contract, two things must be checked together. First, is it specific enough that performance can be objectively verified? Second, does the condition violate public policy?
How the Kolmar Korea Case May Unfold
The core review for the court in the Kolmar Korea case is clear.
- Did the contract at the time of gift contain express, specific rescission conditions?
- If no express conditions, can an implied duty be inferred?
- If express conditions existed, how should it be interpreted whether they were fulfilled or unfulfilled in this specific case?
In my view, recognizing an implied duty is generally very difficult. The case fate will therefore turn on the existence of express conditions and their interpretation.
Frequently Asked Questions
Q. If my parents simply said you will take good care of us, right? when giving stock, can I be required to return it? A. Generally no. Implied duties are very hard to recognize, and abstract filial clauses rarely satisfy a rescission condition.
Q. What if the agreement specified that the child would pay monthly support of KRW X? A. Such concrete conditions allow objective verification of performance, so recognition as a rescission condition is comparatively likely. The agreement should be in writing.
Q. What advantages does a trust offer over a gift? A. The ability to design varied conditions is the essential strength of a trust. Korea adoption is muted due to tax and fee considerations, but will-substitute trusts and which combine lifetime rights and post-mortem transfer and are a growing area.
How to Apply It to Your Family
If you plan to gift assets to your children or grandchildren, the safer sequence is as follows. First, clarify whether the transfer is a simple asset transfer or one premised on performance of a duty. Second, if premised on duty, design that duty as a specific, objectively verifiable condition. Third, check the condition does not violate public policy. Fourth, for gifts of company shares, design with the management-succession structure together.
