In September, the attention of South Korea's business and legal communities will converge on a single courtroom at the Seoul Family Court. The case involves Kwon Hyuk-bin, founder and chairman of Smilegate Group—one of South Korea's leading gaming conglomerates—and his spouse. With assets estimated at roughly 8 trillion won (approximately $6bn), the proceedings extend well beyond a private family matter. They carry profound implications for chaebol ownership structures, the legal principles governing asset division, and corporate governance more broadly.
The 8 trillion won empire built on a single game
Smilegate was founded by Kwon in 2002. Its fortunes were transformed by CrossFire, an online first-person shooter released in 2007 that became a phenomenon in China. At its peak, the game attracted 8 million concurrent players, and cumulative revenues are reported to have reached tens of trillions of won. Building on that windfall, Smilegate diversified: it co-developed Lost Ark with Epic Games, and expanded into virtual reality and artificial intelligence. Today it ranks among South Korea's most significant gaming groups.
Kwon's estimated net worth—encompassing his shareholdings and the assets of affiliated companies—stands at around 8 trillion won. Precise valuation is difficult given Smilegate's unlisted status, but estimates from Forbes Korea and multiple financial industry sources converge on that figure. It is both the central issue in the lawsuit and the source of its broader significance.
How much of that fortune can be divided?
Under South Korean family law, marital asset division covers property jointly accumulated during a marriage. Article 839-2 of the Civil Code grants the right to claim a share of such assets; courts weigh factors including each spouse's contribution, the length of the marriage, and how the wealth was created.
The pivotal question is the extent to which Smilegate's equity qualifies as jointly formed marital property. When a company originates from a single founder's idea and capabilities, determining a spouse's contribution becomes the central legal battleground. Korean courts have typically recognised contributions of between 30% and 40% for non-working spouses, but in cases involving corporate equity, judges often draw strict distinctions between pre-marital and post-marital contributions, and between direct and indirect involvement in the business.
A family law specialist at a large Seoul firm put it plainly: "For corporate equity, what matters most is whether the company was founded before or after the marriage, and whether the spouse contributed—directly or indirectly—to the firm's growth. If a division running into the trillions of won is ordered, restructuring the ownership structure becomes unavoidable."
South Korea's largest divorce case in history
By asset value, this case is without precedent in South Korea. Other high-profile chaebol divorces are sometimes cited for comparison—including cases involving relatives of Samsung's late chairman Lee Kun-hee—but the Smilegate dispute is fundamentally different: the primary asset is the equity stake of a sole founder in an unlisted company.
Internationally, there are precedents for founder divorces shaking corporate structures. When Amazon's Jeff Bezos divorced in 2019, his settlement transferred roughly 4% of Amazon's shares to his former wife, MacKenzie Scott—worth approximately 38 trillion won at the time, making her one of the company's largest individual shareholders almost overnight. Crucially, however, Bezos retained all voting rights, limiting any impact on his control of the company.
Could Smilegate's governance be destabilised?
If the court orders a substantial division of assets, Smilegate's unlisted status creates an immediate practical problem: raising cash. A direct transfer of equity would dilute Kwon's controlling stake, with direct consequences for the stability of his management. Because Smilegate is not publicly traded, assigning a market value to its shares is difficult, creating fertile ground for further disputes.
Industry observers suggest several possible mechanisms: a capital reduction with cash payments to shareholders, expanded dividend distributions, or the sale of subsidiary companies. Some in the investment community have quietly raised the possibility of an initial public offering. A stock market listing would provide a market-based valuation of Smilegate's equity and offer a cleaner path to satisfying any court-ordered settlement.
Two battles in one courtroom
The case encompasses both asset division and a separate claim for consolation damages—the Korean legal concept of compensation for emotional harm caused by the spouse responsible for the breakdown of the marriage. Korean courts typically award such damages in amounts ranging from tens of millions to a few hundred million won: modest sums relative to a multi-trillion won asset division, and largely symbolic. Yet the determination of fault carries indirect weight, since it can influence the court's assessment of the division ratio. Both sides are contesting it vigorously.
The verdict and its aftermath
Legal experts expect the first-instance ruling to be followed by appeals and, potentially, a final appeal to the Supreme Court. In disputes of this magnitude, neither party typically concedes quickly. A definitive outcome could take years.
Even so, the September ruling will send a signal of its own. Whatever share of Kwon's corporate assets the court chooses to recognise as divisible will serve as a benchmark for similar cases to come. South Korea's start-up ecosystem has produced a generation of founder-led, privately held technology and gaming companies. For all of them—and for the spouses of their founders—this verdict will set new legal precedents.
The case also exposes a structural gap in the law. Valuations of unlisted company shares under South Korea's inheritance and gift tax rules are already used in divorce proceedings, but it is common for the two sides' expert appraisals to differ by hundreds of billions of won or more. Specialists argue that family courts need dedicated valuation standards for private-company equity—a reform that this case may help to accelerate.
How a Seoul courtroom rules on 8 trillion won this September could alter perceptions of marital and ownership structures across South Korean business, not just in gaming.
