Claiming a Korean estate from abroad — choice of law, statutory heirs, deadlines, and inheritance tax
Korean inheritance law for foreigners raises a question many families face only after a death: when a relative who lived in Korea, or who owned property in Korea, passes away, who is entitled to the estate, and how is it claimed? Foreign nationals and Koreans living overseas can inherit assets located in Korea, but the process is shaped by rules that differ in important ways from those in other countries.
This page gives an overview of how succession works in Korea for international families — which country's law governs, who counts as a legal heir, the deadlines that cannot be missed, and how an estate can be settled even when the heirs never set foot in Korea.
Nationality is not a barrier to inheritance in Korea. A foreign national can inherit a Korean bank account, real estate, company shares, or other assets, and an heir living abroad does not lose that right simply by being absent. What changes from one case to the next is not whether a foreigner may inherit, but which body of law decides the size of each share and how the estate is divided.
Two situations are the most common. In the first, a Korean national dies leaving foreign heirs — for example, a parent in Korea whose children emigrated and naturalised elsewhere. In the second, a foreign national dies owning assets in Korea — for example, a long-term resident with a Korean bank account or an apartment. The starting point in either case is the choice-of-law rule below.
Under Korea's Act on Private International Law, succession is in principle governed by the national law of the deceased at the time of death (Article 77). The practical consequences are significant.
If the deceased was a Korean national, Korean inheritance law governs the succession, even where every heir is a foreign national living overseas. If the deceased was a foreign national, the law of that country governs by default — although the deceased may, in a will made in proper form, have designated the law of their habitual residence, or, for real estate, the law of the country where the property is located.
This means a foreign national who owns an apartment in Korea can direct that Korean law apply to that property through a valid will. Even when a foreign country's law governs the substance of an inheritance, Korean assets must still be transferred through Korean procedures — registry offices, banks, and, where there is a dispute, Korean courts. Identifying the governing law early is the single most important step, because it determines the heirs, the shares, and the deadlines that follow.
Where Korean law applies, heirs inherit in a fixed order of priority. A surviving spouse does not occupy a separate rank: the spouse inherits jointly with whichever of the first two ranks exists, and inherits alone only where there are no descendants and no ascendants.
| Rank | Heirs | Position of the Spouse |
|---|---|---|
| First | Lineal descendants (children, then grandchildren) | Inherits jointly with them |
| Second | Lineal ascendants (parents, grandparents) | Inherits jointly if there are no descendants |
| Third | Siblings | Spouse inherits alone before this rank is reached |
| Fourth | Other relatives within the fourth degree of kinship | — |
Co-heirs of the same rank share equally, with one adjustment: the surviving spouse receives an additional one-half on top of a child's share. Where a spouse inherits alongside two children, the shares are calculated as 1.5 to 1 to 1 — that is, three-sevenths to the spouse and two-sevenths to each child. These statutory shares apply when there is no will. A valid will can distribute the estate differently, subject to the reserved-share limits discussed below.
Korean inheritance transfers debts as well as assets. An heir who simply does nothing is treated as having fully accepted the estate, including any liabilities. To avoid inheriting debt, an heir must act within three months of becoming aware that the succession has commenced.
Within that window, an heir generally has three options.
| Option | Effect |
|---|---|
| Simple acceptance | The heir takes the assets and becomes fully liable for the deceased's debts. |
| Qualified acceptance | The heir takes the estate but is liable for debts only up to the value of the assets received. Filed with the family court. |
| Renunciation | The heir gives up the inheritance entirely — both assets and debts. Filed with the family court. |
For heirs abroad, the three-month deadline is the most common and most costly trap, because the period can pass while documents are still being gathered overseas. Korean law allows a later qualified acceptance in limited circumstances where debts exceeding the assets are discovered afterwards without the heir's serious fault, but relying on that exception is risky.
Korea imposes inheritance tax on estates, with progressive rates. The return is generally due within six months from the end of the month in which the death occurred. If the deceased or an heir has an address abroad, the filing period is generally extended to nine months.
The rules on deductions, valuation, and the treatment of overseas heirs are detailed, and the tax deadline runs in parallel with the three-month acceptance window. For these reasons, tax and succession planning should begin as soon as the death is known rather than after the estate is divided.
Not every estate is settled smoothly. Common disputes include disagreement over how to divide the estate, claims that a will is invalid, and claims by an heir who has been left out.
Korean law protects certain close heirs, including lineal descendants, the spouse, and in some cases lineal ascendants, through a reserved share. Even where a will or lifetime gifts would leave them with very little, those heirs are guaranteed a minimum portion of what they would otherwise have received. This area changed significantly after a 2024 Constitutional Court decision, which struck down the reserved share for siblings and ordered the legislature to revise other parts of the system. Anyone relying on, or defending against, a reserved-share claim should confirm the current rules with counsel before acting.
An heir who has been wrongly excluded may bring an inheritance-recovery claim, but strict time limits apply — measured from the date the infringement became known and, in any event, from the date of the infringing act. Missing them can end an otherwise valid claim.
Heirs living outside Korea often assume they must travel to Korea to settle an estate. In most cases they do not. A Korean lawyer can be authorised to gather the records that prove the family relationship, file the necessary court applications, deal with banks and the property registry, and represent the heirs in any dispute. Documents issued abroad usually need to be translated and legalised before they can be used in Korea.

A. Yes. Neither foreign nationality nor living overseas prevents a person from inheriting Korean assets such as a bank account, real estate, or shares. What varies from case to case is which country's law decides the heirs and shares, and how the estate is transferred.
A. Under Korea's Act on Private International Law, succession is in principle governed by the national law of the deceased at the time of death. If the deceased was a Korean national, Korean inheritance law applies even where the heirs are foreign. If the deceased was a foreign national, that country's law applies by default, unless a valid will designated otherwise.
A. Usually not. A Korean lawyer can be authorised to gather the records proving the family relationship, file the required court applications, deal with banks and the property registry, and represent the heirs in any dispute. Documents issued abroad generally need to be translated and legalised before use in Korea.
A. If no qualified acceptance or renunciation is filed within three months of learning that the succession has begun, the heir is generally treated as having fully accepted the estate, including its debts. A limited later option exists where major debts are discovered afterwards without the heir's serious fault, but it cannot be relied on in advance.
