Divorce Property Division The Real Variable Is Asset Price Not the Ratio

In divorce property division, the number most clients care about is the division ratio. Disputes break out over 60-40 versus 50-50. But once you take a case through, the biggest factor in the amount a client ends up with is not the ratio but the price of the assets subject to division. This article organizes when and how prices are determined for apartments, listed stocks, and unlisted stocks, and why this matters more than the ratio.

To be honest, an attorneys effort does not move the division ratio by a large range. The basic facts, marriage length, child-rearing burden, occupation and income, timing of asset formation determine most of the ratio. Realistically, an attorneys effort can typically affect 5 to 10 percent, up to about 15 percent on the best-running cases.

Asset prices, however, often move by more than 30 percent within the same case. When the real-estate market is in an uptrend, an apartment can move by hundreds of millions of KRW while the lawsuit is pending. In the end, what the client receives is shaken more by asset prices than by the division ratio.

When a court assesses the price of assets subject to division, the benchmark is the close of fact-finding (close of trial in the trial court for matters that end at trial, or close of argument at the appellate court for those that proceed on appeal).

The problem is that divorce cases can last 1 year at the short end, 2 to 3 years at the long end. Cases of one and a half years at first instance and another one and a half on appeal are common. Apartment prices do not stand still in the meantime.

Current court practice assesses apartment values based on KB real-estate market data. KB indexes reflect monthly movements, so price changes during the case are reflected directly in the division result. When recent uptrends are steep in places like Seouls Gangnam designated transaction-permit zones, value differences of hundreds of millions of KRW between filing and the close of fact-finding are not rare.

Within this structure, strategy diverges by which side the client is on.

• If apartment prices look likely to rise and the client is the receiving side of division, slowing the closing date can be favorable.
• If the client is the paying side, advancing the closing date can be favorable.
• When market direction reverses, the opposite strategy applies.

Of course, such strategic choices are meaningful only within the range where reasonable predictions of price trends are possible. No one predicts the market precisely. But the attorney must understand the structure and impact of price changes to discuss with the client where to wait and when to decide.

Because listed company shares have continuous market pricing, the price at the close of fact-finding is the divisible value. Same logic as apartments.

A representative example is SK stock in the Choi Tae-won and Noh Soyoung divorce. The divisible value was set at the appellate close-of-fact-finding price; after the reversal and remand, a different price formed at the remand stage. Whether the benchmark on remand is the close of the remand or the prior appellate close has not been clearly settled in case law, and that is itself a live dispute.

Where listed stocks make up a large share of the divisible pool, the value subject to division is shaken significantly by market movement. Before fighting over the ratio, the legal argument over which date to use for pricing can be the more important contest.

The most challenging asset is unlisted stock. Unlike listed stocks, there is no market price, and there are no standardized indexes like KB for apartments. Value is determined by appraisal.

Supreme Court precedent looks at unlisted stock value in the following order:

• Where there is a normal transaction example properly reflecting objective exchange value, that transaction price is recognized as the market price.
• Where no normal transaction example exists (which is the case for most individually held unlisted stocks), value is assessed by objective and reasonable materials.

The challenge is that there is more than one appraisal method. Methods commonly used in practice include:

Under the supplementary method, the weighted average uses 3:2 of per-share net earnings to net assets. If the weighted average is less than 80 percent of per-share net assets, 80 percent of net assets is the floor. For real-estate-heavy companies (real estate at 50 percent or more), the ratio flips to 2:3 or net assets only.

The Supreme Court consistently holds that no single appraisal method must always be applied; the courts and the proper method is determined by considering the companys situation and the characteristics of its industry comprehensively to arrive at a fair value.

In short, the choice of appraisal method effectively determines unlisted-stock value. Valuing IT startup shares by the supplementary tax method can land far below actual corporate value; valuing a company with thin assets but big future earnings by DCF can land very high.

Unlisted-stock appraisals are usually done once. That date is treated as the close-of-fact-finding price. Therefore when the appraisal is done is itself a core variable.

On appeal, reappraisal sometimes occurs. The new appraisal date then becomes the benchmark. If the companys results are improving, a reappraisal on appeal can lift the value; if they are deteriorating, it can lower it.

Two traps surface often.

First, focusing only on the ratio and reviewing timing and method of price assessment too late. Decisions to slow or advance the close of fact-finding, or when to set the appraisal date, can change outcomes more, yet the client spends time on ratio fights without analyzing the asset structure.

Second, taking an appraisal with no strategy on unlisted-stock method. Outcomes vary widely with which appraiser is selected, which method the appraiser prefers, and which materials are submitted. Going forward without that pre-review can lead to an outcome unfavorable to the client.

I run simulations on per-asset valuation date and method early in cases with a large asset share. The time spent here changes the amount the client receives more than the time spent on ratio.

Q. At filing the apartment looked good, but prices fall by close of fact-finding. What happens? A. The close-of-fact-finding price is the benchmark, so the lower price is the divisible value. The receiving side loses; the paying side gains. Discuss in advance how to handle the closing date based on reasonable expectations.

Q. Must unlisted stock always be valued by the supplementary tax method? A. No. The Supreme Court does not require a single method. The appropriate method is determined by industry, asset structure, profitability, and presence of transaction examples. Analyze which method suits your case at the start.

Q. Can you redo the appraisal if you do not like the result? A. Reappraisal within the same instance for the same asset is limited. On appeal, reappraisal can occur, and the new timing may change value. Plan the appeal strategy based on the first-instance appraisal.

The real variable that decides divorce property division is the price of the divisible assets, not the ratio. Apartments are priced by KB at close of fact-finding, listed stocks by market price at the same date, unlisted stocks by appraisal, and when and how affects everything. Without reviewing the per-asset valuation structure early, you can win the ratio fight and still end up with less.
