Inheriting Cooperative Equity in South Korea

1. The cooperative says deposits are fine but equity is not. Is that correct?

A father passes away and his children go to the branch office of a Nonghyup (농협), one of the agricultural cooperatives organized under South Korea’s Agricultural Cooperatives Act. The deposits, they are told, can be handled through the ordinary inheritance procedure. Then the conversation turns to the equity contribution (chulja-geum) and the answer changes: “Equity relates to membership status, so all of the heirs must appear and submit the documents together.” In a family where one of four siblings has been out of contact for a decade, that single sentence stops the entire process.

The advice is only half right. Where the heirs wish to succeed to the membership, unanimity really is required. Where they simply wish to recover the money, the position is entirely different. Each heir may claim their own share directly from the cooperative, and that right survives even if another heir objects or cannot be found.

A judgment handed down two months ago addressed exactly this situation. The deceased held equity and ordinary deposits with a cooperative totaling KRW 445,797,424. One of four children demanded payment of a one-quarter share, KRW 111,449,356, was refused, and sued. The court granted the claim in full (Seoul Northern District Court, July 7, 2026, 2026Gadan101295).

One caveat should be stated at the outset. Both of the cases discussed in this article are lower court judgments, and publicly available sources do not confirm whether either became final. The legal principles on which they rest, however, have been repeatedly affirmed by the Supreme Court of Korea, so the outcomes are unlikely to be disturbed. Those principles are set out below.

2. What happens to a member’s equity when the member dies?

The membership ends and the money remains. The Agricultural Cooperatives Act treats death as a ground for automatic withdrawal. Withdrawal is not triggered by an application from the heirs or by a decision of the cooperative; the fact of death alone completes it as a matter of law.

Article 29(2) provides that a member is automatically withdrawn where the member loses eligibility, dies, is declared bankrupt, becomes subject to a ruling for the commencement of adult guardianship, or, in the case of a corporate member, is dissolved (Agricultural Cooperatives Act, Article 29(2)(2)). Article 29(3) directs the board of directors to ascertain whether members fall within any of those grounds. The board’s function is to confirm a withdrawal that has already occurred, not to decide whether it occurs.

Withdrawal gives rise to a right to a refund of the equity paid in. The Bucheon case shows the sequence plainly. The member died on February 9, 2011, and the cooperative processed the withdrawal on the ground of death on February 17 of the same year (Incheon District Court Bucheon Branch, October 14, 2015, 2015Gahap101558). Eight days. The status of member had already ended at that point, and what remained was purely a question of accounting.

This structure matters. The entanglement between equity and membership status belongs to the period before death. At the moment of death, that entanglement has already been undone by operation of law.

3. Can each heir claim their own share of the equity refund?

Yes. A right to a refund of equity is, in the end, a right to be paid a sum of money — a divisible claim. A divisible claim splits automatically among the heirs the instant inheritance commences. No one needs to divide it for them.

The Supreme Court of Korea has confirmed the principle repeatedly.

A claim whose performance is divisible, such as a monetary claim, vests in the co-heirs according to their statutory shares of inheritance automatically upon the commencement of inheritance; and where special circumstances exist, such as the existence of a special benefit or the recognition of a contributory portion, a divisible claim may also become subject to estate division.
— Supreme Court of Korea, December 21, 2023, 2023Da221144

The question is whether cooperative equity falls within that category. The Bucheon court addressed it directly. The cooperative there refused payment to some of the heirs, relying on its internal rules, and the court held:

The claim for refund of equity against the defendant cooperative, the deposit claims against it, and the deposit claims against the defendant credit union are all divisible claims; those claims vested in the heirs of the deceased separately, according to their statutory shares, upon the commencement of inheritance, and the plaintiffs may therefore demand from the defendants the refund of equity and the deposits corresponding to their statutory shares.
— Incheon District Court Bucheon Branch, October 14, 2015, 2015Gahap101558

The facts of that case are worth noting. The deceased left five heirs — a spouse and four children — but only three of them, the spouse and two children, brought the action. The remaining two children took no part. The court nonetheless awarded the three plaintiffs their statutory shares of 3/11, 2/11 and 2/11 in full. The absence of the other heirs did not stand in the way of the claims of those who appeared.

One further point deserves attention: the amount actually recovered. In that case the member had paid in KRW 5 million of equity over nearly forty years beginning in 1971. The refund was considerably larger.

Roughly four times the amount paid in. How a refund is composed depends on the cooperative’s articles of association and its accounting practice, so the figures cannot be generalized. But before assuming that equity “cannot amount to much,” it is worth requesting a written breakdown of the calculation from the cooperative.

4. Must heirs produce documents signed by every co-heir?

If the only basis for that demand is an internal rule of the institution, there is no obligation to comply. An operations manual binds the institution’s own staff; it does not bind a customer or that customer’s heirs. Courts have said so in both of the cases discussed here.

In the Seoul Northern District Court case the cooperative relied on its deposit operations manual. The judgment quotes it: Section 9, Article 3(1) required, upon a request for payment of inherited deposits, the submission of a membership name-change report jointly signed by all heirs; Article 4(2) provided that where some of the heirs demanded payment of their own shares, the request was to be refused, and that if litigation followed, notice of the suit was to be given to all other co-heirs and the matter handled according to the outcome.

The court’s response was brief.

The above deposit operations manual is merely an internal rule effective within the defendant, and cannot be regarded as having effect against the deceased or the deceased’s heirs. There is no evidence whatsoever that, at the time the deceased transacted with the defendant, the parties agreed to incorporate the deposit operations manual into the contract.
— Seoul Northern District Court, July 7, 2026, 2026Gadan101295

The Bucheon judgment is to the same effect. There the cooperative and the credit union argued that payment could not be made because the heirs had submitted no evidence showing the absence of circumstances affecting statutory shares. The court rejected the argument, treating the manuals as nothing more than internal operating guidelines.

A practical qualification belongs here. This principle is difficult to enforce at the counter. In the Seoul Northern District Court case the cooperative refused payment to the end, and the heir ultimately had to litigate. The cooperative’s attempt at a deposit into court against unascertained claimants was also rejected, on the ground that nothing showed a dispute among the heirs. In short, the law favors the heirs, but the place where that law is realized is often the courtroom rather than the branch office.

5. Why is housing subscription savings treated differently?

This question must be confronted, because it contains the strongest argument available to the cooperative. On housing subscription savings (cheongyak jeoceuk), the Supreme Court of Korea reached the opposite conclusion.

Housing subscription savings is, by name, a deposit. Yet when an heir sued for payment of the share corresponding to their statutory portion, the Court rejected the claim.

Where the holder of housing subscription savings, which cannot be separated from the right to apply for housing supply, has died leaving several heirs, the heirs may terminate the housing subscription savings deposit contract only if all of them make the declaration of termination, absent special circumstances such as a differing special agreement with the financial institution.
— Supreme Court of Korea, July 14, 2022, 2021Da294674

The reasoning runs as follows. Housing subscription savings carries with it the right to apply for housing supply; that right cannot be divided, so the heirs hold it in quasi-co-ownership. A financial institution owes no obligation to pay principal or interest until the account is terminated. To obtain the money the heirs must therefore terminate the contract — and Article 547(1) of the Korean Civil Act provides that “where there are several parties on one or both sides, the termination or rescission of a contract shall be made by or against all of them.” Unless everyone acts, no one recovers anything.

If a cooperative invokes that decision and argues that equity likewise “cannot be separated from membership status,” the argument has surface appeal. But there is a decisive difference.

What was at issue in the housing savings case was termination — a declaration ending a contract, to which Article 547(1) applied. In the case of a cooperative member, there is nothing left to terminate. Article 29(2)(2) of the Agricultural Cooperatives Act makes death a ground of automatic withdrawal, so the withdrawal is already complete by operation of law without any act by the heirs. Where no contract remains to be ended, the indivisibility of termination has nothing to attach to.

The structure of the Bucheon judgment illustrates the distinction. There the deposits were treated as terminated by the heirs’ application for a payment order — they had to pass through the gate of termination. The equity, by contrast, became refundable without any such step, because the withdrawal on the ground of death had already been processed.

6. One heir cannot be reached. What can the others still do?

Begin by asking what you are trying to do. An estate stalls not because an heir is missing, but because the particular step being attempted requires unanimity. For the same estate, the answer flips depending on which route is taken.

The Supreme Court of Korea drew this boundary with unusual clarity last year, in a case involving inherited shares whose structure closely resembles that of cooperative equity. Shares also represent a status vis-à-vis a company, are not divisible claims, and are therefore held by the heirs in quasi-co-ownership.

The Court separated two questions. First, it held that so long as the other co-owners do not agree, an heir cannot demand a transfer of title in the register on behalf of all the heirs. Second, it nonetheless opened a route for the heir’s own portion.

Where some of the co-owners of shares do not wish to have the transfer of title entered, so that a transfer reflecting the state of co-ownership cannot be sought, it should be held that one of several co-owners of the shares has an interest in seeking confirmation of shareholder rights against the company on their own. (…) Some of the shareholders co-owning shares have an interest in seeking confirmation of shareholder rights against the company limited to the co-ownership interest they have acquired.
— Supreme Court of Korea, September 11, 2025, 2025Da211120

Even shares, which are held in quasi-co-ownership precisely because they are not divisible claims, may be asserted individually as to one’s own portion. An equity refund claim, which has already been apportioned to each heir, stands on stronger ground still. The cooperation of the other heirs was never an element of the claim.

In short: the fact that a sibling cannot be found is no reason to stop recovering your own money. What stops is the succession of status and the division of the estate as a whole.

7. Can a court substitute for a missing heir’s consent?

Where unanimity genuinely is required, court procedures can fill the gap. Two routes exist, and the choice turns on how long contact has been lost and whether the person is known to be alive.

First, appointment of an administrator of the absentee’s property. Article 22(1) of the Korean Civil Act provides that where a person who has left their former domicile or residence has not appointed an administrator of property, the court shall, on the petition of an interested party or a public prosecutor, order the measures necessary for the administration of the property. A co-heir qualifies as an interested party. Once appointed, the administrator participates in the proceedings on the absentee’s behalf.

The administrator’s authority, however, is limited. Article 25 provides that an administrator appointed by the court must obtain the court’s permission to perform any act exceeding the scope prescribed in Article 118, and Article 118 confines that scope to acts of preservation and to acts of use or improvement that do not alter the nature of the property or right. Consenting to the selection of a successor to cooperative membership determines the destination of estate property and therefore exceeds that scope, so a separate permission for an act beyond authority is required. In practice, failing to plan for that second step leaves the matter stalled again after the administrator has been appointed.

Second, adjudication of disappearance. Article 27(1) provides that where the whereabouts of an absentee have been unknown for five years, the court shall, on the petition of an interested party or a public prosecutor, make an adjudication of disappearance. Where the person encountered a peril likely to cause death — war, the sinking of a vessel, the crash of an aircraft — the period is shortened to one year from the end of that peril (Article 27(2)). A person subject to an adjudication of disappearance is deemed to have died at the expiration of that period (Article 28).

The two procedures are fundamentally different in character. An administrator of an absentee’s property is appointed on the premise that the person is alive, to manage the property in their stead. An adjudication of disappearance treats the person as deceased and reconfigures the succession itself. Once such an adjudication is made, that person’s share passes to their own heirs, which may make the relationships more complicated rather than less.

Where contact has been lost only recently, or where the person is known to be alive, an adjudication of disappearance is unavailable as a matter of the statutory requirements. In practice, therefore, appointment of an administrator is usually considered first.

8. How does an heir succeed to the membership itself?

It is possible, but here unanimity really is required. Unlike a refund claim, this is the one route that genuinely is blocked by an heir who cannot be reached.

Article 28(5) of the Agricultural Cooperatives Act provides:

Where an heir of a member who has withdrawn by reason of death (in the case of co-heirs, this means one heir selected by the co-heirs) has the qualifications for membership under Article 19(1), the heir may succeed to the equity of the decedent and become a member.
— Agricultural Cooperatives Act, Article 28(5)

Two layers of requirements follow. First, the successor must qualify for membership (Article 19(1)). Because a member of a regional agricultural cooperative must be a farmer, a child living in the city cannot succeed without meeting that qualification. Second, where there are several co-heirs, one must be selected. The membership is not shared out among four; it is concentrated in one person, and choosing that person requires the agreement of the rest.

The design reflects the nature of a cooperative. Members exercise one vote each at the general meeting; holding more units of equity does not produce more votes. If four heirs all became members, the single vote their father held would become four, distorting the cooperative’s decision-making. That is why the statute limits succession to one person.

The practical choice therefore divides. If none of the heirs farms or intends to satisfy the qualification requirement, there is little to be gained by attempting succession, and claiming refunds individually is faster. If, on the other hand, one heir will inherit the farmland and continue the operation, succession becomes meaningful — and the question turns to how to secure the unanimity needed to select that one person, which leads back to the procedures in Section 7 where an heir cannot be reached.

9. When does cooperative equity enter an estate division case?

As a rule, it does not. But there is an exception, and in practice it arises often — where a particular child received property during the decedent’s lifetime, or where an heir claims a contribution for having cared for a parent.

Start with the rule. A divisible claim is already apportioned to each heir at the commencement of inheritance, so nothing remains to be divided. It is therefore in principle outside the scope of estate division.

Applied without qualification, however, that rule produces unfair results. The example given by the Supreme Court of Korea is a clear one.

Where there is an heir whose special benefit exceeds their share, that heir would inherit the divisible claim according to the statutory share without returning the excess, producing an unjust result. (…) Accordingly, where such special circumstances exist, it is necessary to achieve equity among the co-heirs through estate division, and therefore a divisible claim may exceptionally become subject to estate division.
— Supreme Court of Korea, Decision of May 4, 2016, 2014Seu122

If the eldest son received an apartment during the parent’s lifetime and the remaining estate consists only of equity and deposits, dividing that remainder by statutory shares is not equitable. Where such circumstances exist, a family court may recalculate the concrete shares of inheritance in an estate division adjudication, cooperative equity included.

Two practical paths follow. Where there is no dispute among the heirs over special benefits or contributory portions, suing in the civil court for one’s own share is the faster route. Where such a dispute does exist, establishing the concrete shares through a family court adjudication is safer. Pursuing separate civil actions while a dispute is live risks results that conflict with the later adjudication and require unwinding.

It is worth adding that the cooperative’s reasoning in the Seoul Northern District Court case amounted to a version of this concern — that the heirs might be in dispute. The court rejected it because nothing indicated an actual dispute. Read the other way, where a dispute genuinely exists, the institution’s objection may carry more weight.

10. What does this mean for foreign heirs and companies in the IFEZ?

Few foreign nationals hold membership in a Korean agricultural cooperative. The principle established in these cases, however, reaches much further: it governs any claim by heirs against a South Korean financial institution, and foreign heirs encounter the same obstacle in a sharper form.

Three points transfer directly.

First, a bank’s internal manual is not law. Korean banks, credit unions and cooperatives routinely require documents executed by every heir before releasing a deceased customer’s funds. Where the sole basis for that requirement is an internal operations manual not incorporated into the contract, it does not bind the heirs. For a foreign heir this matters disproportionately, because assembling notarized and apostilled documents from co-heirs scattered across several countries can take months.

Second, the character of the asset determines whether unanimity is needed. Ordinary deposits are divisible claims and may be claimed share by share. Shares in a Korean company are not; they are held in quasi-co-ownership, and a single heir may assert only their own co-ownership interest (Supreme Court of Korea, September 11, 2025, 2025Da211120). An heir to a mixed estate should sort the assets by this criterion before deciding what can proceed now and what must wait.

Third, an unreachable co-heir does not freeze everything. The distinction drawn in Section 6 applies with equal force to a foreign family: divisible assets can be recovered immediately, while status-linked assets and any global settlement of the estate require the procedures in Section 7.

For foreign-invested companies and their executives resident in the Incheon Free Economic Zone (IFEZ) — across the Songdo International Business District, Cheongna International City and Yeongjong International City — the practical implication is a documentary one. Where a foreign national dies holding assets in South Korea, the estate almost always includes deposits at a Korean institution, and the institution’s first response is almost always a demand for the signatures of all heirs. Knowing that the demand rests on an internal rule rather than on statute changes the negotiating position, and, where the institution will not move, defines the claim to be filed.

11. Frequently Asked Questions

This article summarizes general principles drawn from published decisions of the Supreme Court of Korea, two lower court judgments, and the statutes in force. Publicly available sources do not confirm whether either lower court judgment cited above became final. The outcome of any particular case will depend on the cooperative’s articles of association, the record of equity contributions and transactions, and whether the heirs are in dispute over special benefits or contributory portions.
