Self Made vs Inherited Wealth in Divorce Division

Whenever a conglomerate or high-net-worth divorce property division becomes a public issue, the question I most often receive is whether the court is leaning toward the rich. The short answer is no — the doctrine applied does not change with asset size. But under the same doctrine, the texture of the outcome shifts because of certain core variables. This article compares the self-made and the inherited types and uses the comparison to spell out the doctrine on separate property that also drives ordinary divorce cases.

The starting principles of property division in an ordinary divorce

Before the comparison, let me set the starting line for an ordinary divorce. Assets formed during the marriage by the couple are typically treated as marital property, and absent special circumstances the split tends to settle around 50:50.

But the principle includes the following exceptions.

• The concept of separate property: assets formed through inheritance or gift from a parent are, in principle, separate property and not subject to division.
• The tendency to fold them back in after three years: if the marriage exceeds three years, separate property is typically considered to have been maintained and grown with the contribution of the other spouse, and the practice of folding it back into the divisible pool is now settled.
• Reflecting separate-property character through the ratio: include it in the divisible pool, but reflect its separate-property nature at the ratio-setting stage.

Now let us see how this principle plays out differently for self-made and inherited cases.

Self-made type: assets built by joint effort

Representative examples of the self-made type include the NCsoft Kim Taek-jin couple, the Amazon Jeff Bezos couple, and the Smilegate Kwon Hyuk-bin couple currently before the family court.

This category has the following features.

• The bulk of the marital assets was formed through the parties own efforts during the marriage, not through inheritance or gift.
• The assets often take the form of company shares, but the fact that they are shares is not itself a reason to exclude them from division.
• The starting point is therefore a 50:50 split.

When the couple assets far exceed an ordinary range, however, the fact that one person extraordinary capacity was decisive to building those assets is also weighed. In those cases, simplifying to a flat 50:50 is hard. The starting point of 50:50 stays, but the exceptional capacity is reflected by adjusting the ratio.

On the divisibility of company shares, one more note. Some worry that dividing shares may affect corporate control, but my position is that a divorce case is fundamentally about dividing the couple property, not about preserving the corporate governance of a company. Managerial risk from the division is closer to a separate management concern of the parties and the company.

Inherited type: separate-property character is the central issue

Representative examples of the inherited type include the Lee Boo-jin Hotel Shilla couple and the Cho Hyun-ah former Korean Air vice-president couple. The Noh So-young / Chey Tae-won case is closer to a mixed self-made / inherited matter.

This category has the following features.

• The bulk of the marital assets is separate property formed through parental inheritance or gift.
• The central issue is therefore not the ratio, but whether the separate property should be brought into the divisible pool at all.
• In ordinary cases the three-year-and-fold-in pattern is settled, but in inherited high-net-worth cases there are not a few rulings that exclude the assets from the divisible pool.

In Lee Boo-jin case, the Samsung-related shares excluded from the divisible pool were assets whose value had grown sharply through the special features of the inheritance and gift process. In the Cho Hyun-ah case, a significant portion of the Korean Air–related shares is reported to have been treated as separate property. The first-instance judgment in the Noh So-young / Chey Tae-won case originally excluded the SK-related shares from the divisible pool entirely as separate property.

Same doctrine, different outcomes — what divides the result

In my consultations, the question I most often hear is why separate property gets folded into the divisible pool after just three years in ordinary cases but not in high-net-worth cases. I explain it this way.

The doctrinal core is how much the other spouse contributed to maintaining and growing the asset. For ordinary couples, the very fact that the asset has been maintained over more than three years of marriage is treated as a certain level of contribution, and it gets folded into the divisible pool.

In very high-net-worth cases, two factors operate simultaneously.

• The floor problem for ratios: ratios are typically set in units of at least 5% to 10%. Fine adjustments like 1% versus 99% are almost never made in practice.
• The proportionality problem between contribution and result amount: even at a 10% ratio, if the divisible pool is in the trillions, the divided amount runs into the hundreds of billions. When that amount cannot reasonably be attributed to the other spouse contribution, the court may instead treat the asset as separate property and exclude it from the divisible pool.

Worth remembering in an ordinary divorce too

The comparison carries the same message for ordinary divorce cases.

• Separate property is not automatically excluded from the divisible pool. Marriage duration, contribution to maintenance and growth, and the character of the asset are all weighed together.
• Conversely, marital property is not automatically split 50:50. How the asset was formed and any extraordinary individual contribution are reflected in the ratio.
• The fact that an asset takes the form of company shares does not lower the prospects for division. Like real estate or deposits, shares are evaluated as divisible. With unlisted shares, however, valuation is a separate domain, and disputes over the valuation method itself can swing the result substantially.

Frequently asked questions

Q. In a self-made case, are all the assets split 50:50? A. The starting point is usually close to 50:50, but if the party extraordinary capacity was decisive to building the assets, the ratio is adjusted.

Q. Are inherited shares always excluded from the divisible pool? A. Not always. In ordinary marriages, the practice is to fold them in once the marriage exceeds three years. The result can shift, however, depending on the scale of assets and the specifics of the case.

Q. If unlisted company shares are part of the divisible pool, how is value determined? A. Several valuation methods exist, and the result amount changes meaningfully with the method. Because the valuation method itself is a central axis of the dispute, the support of an attorney who understands valuation is decisive.

The same principles apply regardless of asset size

In my consultations, the cases I most often handle are matters where the family is not a conglomerate but the dispute centers on assets received from parents. The reason the comparison between self-made and inherited matters speaks to ordinary divorce cases is that the same doctrine is at work. Scale only widens the range of the outcome.
