130 million won a day — and counting

On 24th July 2026, a Korean court ordered Chey Tae-won, chairman of SK Group, to pay 944 billion won (roughly $690m) to his former wife, Noh So-young, director of the Nabi Art Centre. What looks on the surface like a private matrimonial dispute is, in reality, a ruling capable of shaking the foundations of Korea's corporate world and its stockmarket.

At 944 billion won — just shy of one trillion — the sum is staggering enough. Apply the statutory rate of default interest, and the bill grows by approximately 130 million won every single day. The longer Chey contests the ruling or delays payment, the larger the total liability becomes.

Seven years in court: a timeline

The case has a long history.

2019: Chey Tae-won filed for divorce from Noh So-young. The proceedings drew public controversy when the existence of a child from an extramarital relationship was revealed.

December 2022: The court of first instance awarded Noh approximately 66.5 billion won in the asset division — a relatively modest sum, reflecting the court's view that she had contributed little to the accumulation of SK's core assets, including its shares.

September 2023: The Seoul High Court overturned that verdict on appeal, raising the award dramatically to 1.38 trillion won. The appellate judges took a far broader view, crediting the possible flow of funds from Noh's father — the late former president Roh Tae-woo — into SK's predecessor company in its early years, as well as Noh's intangible contributions as a partner throughout the marriage.

The Supreme Court: Chey appealed to the Supreme Court, which referred the case to its Grand Bench — a full sitting of all justices, reserved for matters of significant legal principle.

24th July 2026: The final ruling set the award at 944 billion won. Lower than the appellate court's figure, but more than fourteen times the original judgment — and the largest divorce asset settlement in Korean history.

Why the bill is so large: three pivotal questions

① How to value controlling shares. The SK Group shares held by Chey are not merely personal wealth; they are inseparable from the governance structure of one of Korea's largest conglomerates (known as chaebol). The appellate court classified a substantial portion of them as marital assets jointly accumulated during the marriage — a categorisation with enormous financial consequences.

② The Roh Tae-woo funds. Noh's legal team argued that money connected to her father, the late President Roh Tae-woo, had flowed into what was then called Sunkyong Group in its formative years. The central question was whether this made the resulting wealth a pre-marital asset belonging to Chey alone, or one formed jointly during the marriage.

③ The scope of non-financial contribution. Under Korean family law, asset division accounts not just for income earned but for intangible contributions — domestic labour, emotional support, and the role of a corporate spouse. This ruling is widely seen as setting a new benchmark for how broadly Korean courts will interpret those contributions.

How does Chey pay?

Finding 944 billion won in cash is no simple matter. Markets are focused on two scenarios.

Scenario one: selling shares. The most direct route is for Chey to sell part of his stake in SK Inc. or other group affiliates. The problem is obvious: a controlling shareholder dumping large quantities of stock onto the market puts immediate downward pressure on the share price.

Scenario two: loans or in-kind settlement. Chey could borrow against his shareholding as collateral, or reach an agreement with Noh to transfer shares directly rather than cash. This second option carries the more dramatic implication: if Noh were to receive SK shares outright, she would become a significant shareholder in her own right — and the group's ownership structure would shift in ways that are difficult to predict.

Market implications: short term and long

Immediate reaction

The shares of SK Group affiliates are the first to feel the pressure. Fears of forced selling by the controlling shareholder, combined with uncertainty over future ownership, are likely to weigh on investor sentiment. This pattern — chaebol owner risk triggering a temporary sell-off in group stocks — has repeated itself many times in Korean market history.

Structural risk one: governance uncertainty

SK Group operates through a holding-company structure: Chey Tae-won controls SK Inc., which in turn holds stakes across the group's subsidiaries. Any significant dilution of Chey's position in SK Inc. — or the emergence of Noh as a major shareholder — could destabilise that structure. Governance uncertainty is precisely the kind of risk that drives away foreign institutional investors. Given that the SK stable includes SK Hynix, SK Telecom, and SK Innovation — all among the largest constituents of the KOSPI, Korea's benchmark equity index — disruption at the top of the group has implications well beyond the family concerned.

Structural risk two: the Korea discount, reignited

Korean equities have long traded at a discount to comparable companies elsewhere, a phenomenon known as the "Korea discount." Analysts attribute it largely to the opacity of chaebol governance — founder families retaining control through cross-shareholdings and related-party structures that are difficult for outside investors to scrutinise. This ruling demonstrates that a chaebol patriarch's personal legal affairs can produce sudden, large-scale shifts in the ownership of flagship companies. Investors may now demand a higher uncertainty premium for holding Korean blue-chip stocks.

Structural risk three: regulatory and governance reform

A ruling of this magnitude sends a chill through the entire business establishment. The realisation that a family divorce can threaten a conglomerate's ownership structure creates a powerful incentive for chaebol groups to restructure pre-emptively — dispersing shareholdings, clarifying the boundary between family wealth and corporate assets, or exploring dual-class share structures that preserve control without concentrating it so nakedly in a single individual. Paradoxically, this case may prove to be the catalyst that accelerates long-overdue improvements in Korean corporate governance.

Structural risk four: a litigation contagion

By firmly establishing that a controlling shareholder's stake can be treated as a marital asset subject to division, the courts have set a precedent. Other wealthy families locked in divorce or inheritance disputes may now advance similar arguments. The risk is therefore not confined to SK Group: it extends, as a structural uncertainty, to chaebol stocks more broadly.

Why this judgment matters

This is not simply the end of a marriage. The ruling carries historical weight on three distinct levels.

First, it establishes legal precedent: the judiciary has now clearly affirmed that a chaebol owner's controlling shareholding can be subject to matrimonial asset division.

Second, it delivers a warning to the business world: the line between personal wealth and corporate control is far blurrier than most chaebol families had assumed — or hoped.

Third, it creates a new variable for investors: analysing a Korean conglomerate now requires factoring in the legal circumstances of its controlling family, not just its balance sheet.

Nine hundred and forty-four billion won is not merely a divorce settlement. It may prove to be the number that marks a new turning point for Korean capital markets and corporate governance alike.
