SK Hynix Chairman Chey Tae-won is locked in one of South Korea’s most expensive divorce settlements, with the dispute centered on a 1.38 trillion won payout—approximately $917 million to $1 billion—that he refuses to pay in full. The billionaire semiconductor executive faces a prolonged legal battle with his ex-wife Roh Soh-yeong, whose financial claims were upheld by South Korea’s Supreme Court in a landmark ruling that sent his wealth calculation into unprecedented territory. This case has become the kind of high-stakes wealth dispute that commands national attention precisely because it raises questions about how much a spouse contributed to building a corporate empire and what that contribution is worth.
The two appeared at Seoul High Court on June 23-24, 2026, marking their first face-to-face meeting in more than two years. The session ended without agreement, and the court has scheduled resumed hearings on June 26, 2026, to continue working through the property division issues. This is not a routine divorce case disappearing behind closed doors; it’s a public calibration of wealth, power, and the financial obligations that accompany them in one of Asia’s most influential semiconductor companies.

What Makes This SK Hynix Divorce Settlement So Unusually Costly?
The 1.38 trillion won settlement represents one of South Korea’s largest divorce settlements on record, but the number alone doesn’t explain the legal ferocity. Chey Tae-won’s wealth is concentrated in SK Group, one of the country’s largest conglomerates, and SK Hynix is the crown jewel of his empire. Courts must assign a financial value to his stake in a company that manufactures memory chips essential to global computing infrastructure. The challenge arises because marital property division depends partly on determining what property was acquired during the marriage and what role each spouse played in its accumulation.
Compare this to divorces involving liquid assets or real estate—where value is straightforward to calculate—and the complexity becomes immediately apparent. When property includes a significant stake in a major corporation, lawyers, accountants, and judges must reconstruct years of business growth and make subjective judgments about spousal contribution. The appeals court that originally awarded Roh Soh-yeong the 1.38 trillion won settlement concluded that her role in SK Group’s growth was substantial enough to justify a larger payout than Chey argues is warranted. He has challenged this assessment at every level, arguing that the court overstated her contribution and therefore overstated her legal entitlement to his wealth. This is precisely where the Supreme Court ruling becomes significant: it upheld the lower court’s evaluation and forced the case into retrial at Seoul High Court, ensuring that the dispute will not be resolved quickly or cheaply.
The Supreme Court’s Reversal and What the Retrial Actually Means
South Korea’s Supreme Court did not rule on Roh’s entitlement in a way that favored Chey; instead, the court overturned the original record settlement and ordered a retrial, which is often read as a partial victory for Chey but carries considerable risk. A retrial does not mean the settlement will be reduced or eliminated. It means the case goes back to a lower court with instructions to reconsider certain aspects, typically within a framework established by higher court precedent. In Chey’s situation, the retrial at Seoul High Court represents an opportunity to challenge the valuation of SK Group assets and the method by which spousal contributions were calculated—but the burden remains on him to prove that the courts got it wrong the first time.
The danger for Chey is that a retrial can result in the same judgment, a higher judgment, or a lower one. South Korean courts have become increasingly sophisticated in evaluating corporate asset division, and precedent from comparable high-profile cases suggests that spouses who were married during periods of significant corporate growth can argue for material contributions that justify substantial settlements. The fact that the Supreme Court sent the case back rather than affirming the lower court’s decision outright suggests the possibility that some element of the valuation process was flawed—but not necessarily in Chey’s favor. The scheduled hearings in late June 2026 will determine whether the Seoul High Court maintains its position or adjusts the settlement figure.
Who is Roh Soh-yeong and What is Her Legal Claim Based On?
Roh Soh-yeong’s legal claim rests on her status as Chey’s spouse during the accumulation of a substantial portion of his wealth and her alleged role in supporting SK Group’s expansion. South Korean family law recognizes the principle that marital property belongs to both spouses, even when one spouse does not directly participate in earning it, if the marriage existed during the asset-building period. Roh has argued that her presence in Chey’s life during SK Group’s major growth phases entitled her to a share of the resulting wealth. This is not a unique argument in divorce cases, but it carries exceptional weight when the wealth in question amounts to billions of dollars and controls a major corporation.
The appeals court that originally sided with Roh concluded that her contributions—whether as a spouse managing household affairs, providing emotional support, or participating in business social functions—were significant enough to justify awarding her approximately 1.38 trillion won. Critics of this approach argue that it extends spousal entitlements too far and fails to distinguish between spouses who actively participate in business growth and those who benefit passively from it. Supporters contend that a spouse’s role in maintaining the household and supporting the executive’s professional life is itself a form of contribution that warrants recognition in property division. The retrial at Seoul High Court will effectively ask whether the original court’s assessment of Roh’s contribution was reasonable.
The Financial Impact on Chey’s Net Worth and Business Holdings
A settlement of 1.38 trillion won would represent a material reduction in Chey Tae-won’s net worth, though the precise percentage depends on how his total wealth is calculated and what assets SK Group holds at any given time. As a billionaire with significant equity stakes in SK Hynix and other SK Group subsidiaries, Chey would likely need to liquidate assets or arrange financing to pay a settlement of this magnitude in cash. This creates a practical problem that many ultra-high-net-worth individuals face: their wealth is concentrated in business holdings that cannot be quickly converted to cash without triggering tax consequences and market effects.
If Chey is forced to sell SK Hynix shares to finance the settlement, he risks diluting his voting control of the company and signaling to markets that he is under financial pressure. Compare this situation to a divorce involving a billionaire with diversified liquid assets, and the burden becomes clearer. Liquidating real estate, stocks, and bonds to pay a settlement is manageable compared to unwinding stakes in a family-controlled conglomerate where voting control and business continuity matter as much as financial return. The retrial creates additional uncertainty about the exact amount Chey will ultimately owe, which complicates his ability to plan financially and structure any potential settlement arrangement.
Corporate Governance and What Happens to SK Hynix During the Legal Battle
One limitation of public attention to this case is the assumption that the legal dispute will not affect SK Hynix’s operations—but prolonged uncertainty around a chairman’s personal finances can create governance risks and investor concerns. SK Hynix must compete in a global semiconductor market where investor confidence and leadership stability matter. If Chey is perceived as distracted by a major personal legal matter, or if he is forced to make unexpected asset sales or business changes to finance the settlement, SK Hynix could face stock price volatility and operational challenges.
The company has separate professional management structures, so it is not entirely dependent on Chey’s day-to-day attention, but the chairman’s role in strategic decisions and his control over family assets means that his personal legal troubles have corporate implications. A warning here is warranted: high-profile divorces involving major shareholders often precede unexpected changes in corporate structure, leadership, or strategic direction. In some cases, the pressure to liquify assets or arrange financing leads to board-level decisions that would not otherwise have been made. SK Hynix investors and competitors have reason to monitor the settlement proceedings closely because the outcome could influence the company’s capital structure or Chey’s willingness to pursue major business initiatives.
Comparing South Korea’s Divorce Settlement Standards to Other Wealthy Nations
South Korea’s approach to marital property division is stricter than some other wealthy nations but less egalitarian than others. In many European countries and some US states, spousal contributions are evaluated through formulas that can result in 50-50 property splits regardless of who earned the income. South Korea uses a more discretionary approach that considers the spouse’s specific contribution during the marriage, which can result in smaller settlements when courts determine the contributing spouse’s role was limited.
However, Korean courts have increasingly recognized non-monetary contributions and awarded substantial settlements in cases involving major asset accumulation. The Chey-Roh case falls into the category of disputes where Korean courts have determined that even passive spousal presence during wealth building warrants significant financial recognition. By contrast, a similar case in the United States might result in a settlement within a certain percentage range of joint marital property, with less subjective debate about the spouse’s contribution. In South Korea, the debate itself becomes a major litigation point, as happened here, and can extend the case over years with multiple appeals and retrials.
The Antitrust Angle and the Broader Troubles Facing SK Hynix Leadership
In a separate development that compounds the legal and reputational challenges facing SK Hynix, US consumers filed an antitrust lawsuit alleging that Samsung, SK Hynix, and Micron revived price-fixing arrangements for DRAM computer memory products. This lawsuit is not directly connected to Chey’s divorce but represents another major legal exposure for the company he controls. The timing of simultaneous disputes—a personal wealth battle requiring potential asset liquidation and an antitrust action that could result in corporate penalties or damages—creates a compound pressure on the executive and the company. While antitrust cases and personal divorce cases are legally separate, they share one thing in common: they both create situations where executives are distracted, companies face uncertain financial liabilities, and stakeholders must account for additional risk.
Chey is not personally accused in the antitrust matter, but as chairman of SK Hynix, he is responsible for the company’s exposure and response. The convergence of these two major legal troubles illustrates why high-profile cases involving billionaires rarely exist in isolation. They tend to cluster during periods of stress, and the pressure from multiple directions can force difficult choices about asset allocation, legal strategy, and business priorities. The Seoul High Court’s June 26, 2026, hearing on remaining property division issues will likely set the trajectory for the final settlement amount, with all of these pressures factoring into whether any negotiated resolution becomes possible.
