A Seoul High Court ruling has ordered SK Group Chairman Chey Tae-won to pay 944 billion won ($644 million) to his former wife, Roh Soh-yeong, capping a decade of public family warfare that reached the highest levels of corporate and political power. The decision marks the largest divorce settlement in South Korean history, even after the award was reduced from an earlier 1.38 trillion won appellate judgment. Crucially, the court ordered Chey to satisfy the obligation in cash rather than transferring equity in SK Inc., ensuring that the billionaire retains his personal grip over South Korea's second-largest conglomerate.
The legal marathon began in earnest after Chey publicly acknowledged an extramarital affair and a child born out of wedlock in 2015. What followed was not a simple domestic separation, but a high-stakes constitutional clash over how marital property is defined within South Korea's family-run industrial dynasties, known as chaebols.
The Financial Mechanics Behind the Verdict
At the core of this legal dispute was Chey's 17.9 percent stake in SK Inc., the central holding company that anchors an empire spanning semiconductors, telecommunications, energy, and electric vehicle battery production.
For years, corporate leaders in South Korea operated under the assumption that inherited wealth or company equity held in an executive's name remained protected as separate property during a divorce. Chey's defense team repeatedly argued that his holdings in SK Inc. were acquired through inherited family resources and personal management contributions, making them immune to asset division.
The courts ultimately rejected that shield.
The Seoul High Court maintained that equity acquired and expanded during a decades-long marriage falls squarely within the pool of divisible marital property. In doing so, the judges acknowledged that non-financial contributions—including homemaking, child-rearing, and institutional support provided by a spouse—directly facilitate the preservation and growth of corporate wealth.
When assessing the total pool of divisible wealth, the court set a baseline contribution ratio of two-thirds for Chey and one-third for Roh.
The financial total was influenced heavily by the explosive growth of SK Hynix, the group's semiconductor flagship. SK Hynix emerged as a primary supplier of high-bandwidth memory chips essential for global artificial intelligence infrastructure. That operational surge drove up the broader market capitalization of SK Inc., dramatically increasing the calculated asset pool during litigation.
To prevent institutional instability, the judges stipulated that the 944 billion won must be paid in cash. Forcing a direct division of shares would have fragmented Chey's equity stake, potentially triggering a corporate governance crisis or opening the door to hostile takeover threats.
Political History and the Slush Fund Dispute
The dispute was further complicated by the political history connecting two of South Korea's most influential families.
Chey married Roh in 1988, uniting the founding family of SK Group with the household of Roh Tae-woo, South Korea's former president.
During earlier appellate proceedings, Roh's legal team presented promissory notes indicating that her father had funneled 30 billion won in undisclosed funds to Chey's late father, former SK Group Chairman Chey Jong-hyun, during the early 1990s. The appellate court initially accepted this claim, ruling that political influence and capital from the former president contributed significantly to SK Group's expansion into telecommunications and energy.
That line of reasoning hit a wall at the Supreme Court.
The top court ruled that illicit funds or political capital linked to criminal activity could not be recognized as a legitimate marital contribution under civil law. Former President Roh Tae-woo had previously been convicted of collecting hundreds of millions of dollars in illegal bribes during his presidency.
Because the Supreme Court threw out the claim regarding the presidential slush fund, the High Court was required to recalculate the division ratio on remand. Removing the 30 billion won political fund reduced the final figure from 1.38 trillion won down to 944 billion won, offering Chey a substantial reduction while preserving the core legal principle that corporate equity acquired during marriage remains subject to division.
Liquidity Realities and Controlling Interest
While 944 billion won is a staggering sum, it does not threaten Chey's ultimate control over SK Group.
Chey's net worth has expanded rapidly, supported by SK Hynix's dominant market position in high-bandwidth memory. Analysts estimate his overall fortune at roughly $5.6 billion, meaning the court order represents approximately 12 percent of his wealth.
To raise the required cash, Chey has several clear avenues that avoid liquidating his primary SK Inc. equity.
- Equity-collateralized loans: Chey can pledge his existing shares as collateral to secure bank credit lines, spreading the financial burden across multi-year amortization schedules.
- Non-core asset sales: Unlisted personal shareholdings, such as his stake in silicon wafer manufacturer SK Siltron, provide immediate liquidity without compromising holding company votes.
- Special dividend distributions: SK Inc. could adjust dividend payout schedules to flow capital directly to major shareholders, allowing Chey to meet cash obligations over time.
Because the court explicitly refused to award shares directly to Roh, Chey avoids the risk of an aggressive activist investor acquiring a voting block or an external hostile entity exploiting family friction. Control over SK Hynix, SK Telecom, and SK Innovation remains firmly anchored at the top of the existing corporate hierarchy.
Implications for Chaebol Governance and Precedent
This legal outcome alters the playbook for South Korea's wealthiest business families.
Historically, founding families maintained absolute ownership over corporate assets by treating holding company equity as private, indivisible property. Spousal claims in divorces routinely ended in minor cash settlements that left corporate structures entirely untouched.
This judgment sets a permanent legal standard.
Courts in South Korea now explicitly recognize that executive spouses contribute directly to corporate asset growth through long-term institutional stability and domestic support. The decision establishes that holding company equity built during a long marriage is fair game in asset division disputes.
Future generations of chaebol heirs will no longer be able to count on automatic judicial immunity for corporate shares during domestic breakups. Pre-nuptial agreements, restructured voting trusts, and isolated holding entities will likely become standard operating procedure across major conglomerates seeking to insulate corporate management from personal family court proceedings.
Chey retains his corporate empire, but the legal framework surrounding South Korea's commercial dynasties has been permanently redrawn.
