SK Hynix Chief Ordered to Pay $644M in South Korea's 'Divorce of the Century'

A South Korean court has ordered Chey Tae-won, the chief executive of SK Hynix, one of the world's largest semiconductor manufacturers, to pay his ex-wife Roh Soh-yeong $644 million in what observers are calling one of the country's most significant spousal settlements. The judgment, handed down this week, represents a substantial financial obligation—yet it fell short of what Roh had originally sought in the dissolution of their marriage.

Chey Tae-won sits atop one of South Korea's most powerful industrial empires. SK Hynix, the conglomerate he leads, manufactures memory chips that power everything from smartphones to data centers, making it a cornerstone of the nation's technology sector and a major player in global markets. The company's reach extends across semiconductors, petrochemicals, and other industrial domains. For someone in Chey's position, the accumulation of wealth is not merely personal—it is intertwined with corporate holdings, stock portfolios, and complex financial instruments that courts must carefully parse when dividing marital assets.

Roh's claim for a larger settlement reflects the scale of wealth at stake in this dissolution. In high-net-worth divorces, the gap between what one party seeks and what a court ultimately awards can be vast, shaped by how judges assess contributions to the marriage, the nature of assets acquired during the union, and the legal frameworks governing spousal support in South Korea. The $644 million judgment suggests the court found merit in Roh's position but did not grant the full measure of her demands.

The case has drawn intense attention in South Korea, where corporate leadership and family wealth remain deeply intertwined, and where divorce settlements involving billionaires are rare enough to command national scrutiny. The media has dubbed it the "divorce of the century," a label that speaks both to the sums involved and to the prominence of the parties. For a nation where Confucian traditions have long shaped attitudes toward marriage and family, such a public dissolution of a high-profile union carries cultural weight beyond the legal and financial dimensions.

The ruling may influence how South Korean courts approach asset division in future cases involving major conglomerate leaders and their families. When the head of a company worth billions goes through a divorce, questions arise about what constitutes marital property, how to value stock holdings and corporate control, and what obligation a spouse has to share in wealth accumulated during the marriage. Each ruling in such cases becomes a reference point for lawyers and judges navigating similar disputes.

For Roh, the $644 million represents a significant financial outcome—enough to secure her future independently. Yet the fact that she sought more underscores how contested these valuations can be, and how even substantial awards may not fully reflect what one party believes is owed. For Chey, the judgment is a substantial liability, though one that his corporate position and wealth allow him to absorb. The broader question now is whether this settlement will reshape expectations in South Korea's wealthiest divorce cases, or whether each will continue to turn on its own particular facts and the judge's assessment of fairness.
