Forced Share (Yuryubun) in Korea: A Guide for Foreign Heirs

“My father left almost everything to my brother — can I do anything from here, or is it too late?” Questions about the forced share in Korea usually arrive in that shape: a family member abroad has seen a will or a registry record, realised the estate has gone elsewhere, and is unsure whether Korean law gives them any claim and how long that claim lasts.

This article explains what the forced share is, who can claim it after the 2024 change, why the governing law matters so much for a foreign family, and where the outcome stops being a simple calculation and becomes a matter of judgment. It is general information on Korean law, not advice on your specific estate.

What the Forced Share Is

A person in Korea is, in principle, free to dispose of their property by will or by gift. But if that freedom were absolute, a surviving spouse or child could be left with nothing. The forced share (yuryubun) exists for exactly that situation: it guarantees a defined group of close relatives a minimum slice of the estate, set as a fraction of what they would have received as their statutory share. A forced-share claim is not an argument that the will is invalid. It accepts the deceased’s wishes but enforces the floor the law places beneath them, allowing a qualifying heir to recover the shortfall.

Crucially, that figure is a starting point for a calculation, not a number that can be read straight off the size of the estate. As set out below, what is finally recoverable depends on which gifts are added back, how the assets are valued, and when the clock started.

Who Can Claim Now — and What the 2024 Decision Changed

The group entitled to a forced share narrowed in 2024. The Constitutional Court, in its decision of April 25, 2024 (Case No. 2020Hun-Ga4 and others), struck down the forced share that had been given to the deceased’s siblings, and the Civil Act as amended no longer lists them. The remaining holders, and the fraction each is guaranteed, are as follows.

The figure in the right-hand column is a fraction of the statutory share, not of the whole estate, and the statutory share itself depends on who survives the deceased. That the siblings’ forced share is gone is settled. Other aspects of the forced-share rules continue to develop through legislation and case law, so for any particular estate the precise position should be confirmed against the current Civil Act and the date the inheritance commenced.

The First Question for a Foreign Family: Whose Law Applies

For an estate with no foreign element, the rules above simply apply. For a foreign family, there is a prior question that decides whether the Korean forced share is even in play. Under Korea’s conflict-of-laws statute, succession is in principle governed by the national law of the deceased at the time of death. A person may, in the form required for a will, instead designate the law of their habitual residence — but only if they keep that habitual residence until death — or, for real property, the law of the place where the property is located.

The practical consequences are significant. Where the deceased was Korean, or validly chose Korean law, the Korean forced share applies in full. Where the deceased was a national of another country, that country’s law may govern the succession — and many common-law jurisdictions allow far broader testamentary freedom, with no forced heirship at all. So the same disinheritance can give a strong claim under one law and none under another, and the analysis of which law governs is itself fact-specific. For a cross-border estate, this is the question to settle first, because it determines whether there is anything to claim before any sum is ever calculated.

Where the Money Is Actually Decided: the Base Estate

When Korean law does govern, the real contest is rarely over the fraction. It is over the base estate — the figure the fraction is applied to. The base estate is the property the deceased left at death, plus certain lifetime gifts added back, less debts. Most disputes turn on which gifts get added back, because that is where an estate that looks empty can be reconstructed into something substantial.

A gift to a co-heir — for example, a large transfer to one child years earlier — is in principle added back regardless of when it was made. A gift to someone who is not an heir is added back only on narrower terms: where it was made within one year before death, or where both the giver and the recipient knew the gift would harm a forced-share holder. The same word, “gift,” can therefore lead to opposite results depending on who received it.

The form of a transaction does not settle the matter either. The Supreme Court has held that whether a disposition counts as a gift to be added to the base estate is judged by its substance — whether it actually reduced the deceased’s estate as a gratuitous transfer — rather than by its formal or abstract character (Supreme Court decision of June 13, 2024, Case No. 2023Da304568). A transfer that does not look like a gift on paper can still be brought into the calculation once its substance is examined.

Because so much depends on which transfers are included and on the date used to value real estate or shares, an online formula that promises “your forced share is X” cannot be relied on. Two careful advisers can reach materially different figures from the same family history, which is precisely why the base estate, not the fraction, is where these cases are won or lost.

One Year — the Deadline That Catches Heirs Abroad

A forced-share claim does not wait. It lapses one year after the holder comes to know both that the inheritance has commenced and that there was a gift or bequest that should be returned; and, separately, it lapses ten years after the death regardless of knowledge. Whichever period expires first controls.

The difficulty is that the “knowledge” trigger is often anything but clear. An heir who is not told about a lifetime gift, and only later pieces it together from a property registry or bank records, may genuinely dispute when their year began. An heir living overseas, learning of a death and its circumstances at a distance, faces the same uncertainty in sharper form. The right can be real and still be lost to a deadline, so where the outline of a gift or a will is even faintly visible, the safer course is to check the timing before anything else.

A Pattern We See Often

A recurring situation looks like this. A parent who lived in Korea dies, and a child who settled abroad years ago learns — sometimes months later — that most of the estate had already been transferred to a sibling who stayed nearby, or was left to that sibling by will. From overseas, and often without Korean-language records in hand, the child cannot easily tell whether the transfers would be added back to the base estate, how the remaining property should be valued, or when their one-year window began. By the time the documents are gathered, the period may already be running. None of this means the claim is hopeless; it means the early questions — governing law, what counts as part of the estate, and timing — are the ones that decide how much room is left to act.

Where the Calculation Ends and Judgment Begins

The fraction and the deadline can be read off a page. The parts of a forced-share dispute that actually move the result — whether Korean law governs at all, which lifetime gifts are added to the base estate, how Korean real estate is valued, and when the one-year clock started for an heir abroad — are matters of judgment on which careful people can differ on the same facts. This is an area where Korea handles fewer cross-border estates than ordinary domestic ones, the whole process runs in Korean, and an early misjudgement on governing law or timing is hard to undo once a position is taken.

Our office handles matters involving Korean estates and cross-border families — claims to a forced share, disputes among heirs over what belongs in the estate, and representation before the Korean courts. Having worked these questions from more than one side helps in framing a claim while there is still time to act, rather than after a deadline has closed the options.

Frequently Asked Questions

Who can claim a forced share in Korea now, and can siblings still claim?

Following the Constitutional Court’s decision of April 25, 2024 (Case No. 2020Hun-Ga4 and others), the forced share for the deceased’s siblings was struck down, and the Civil Act as amended no longer lists them. The forced share today is reserved for lineal descendants, the spouse, and lineal ascendants.

Does Korea’s forced share apply if the deceased was not a Korean citizen?

Not automatically. Under Korea’s conflict-of-laws rules, succession is in principle governed by the national law of the deceased at the time of death; a will may instead designate the law of the deceased’s habitual residence (kept until death) or, for real property, the law where the property is located. Korea’s forced-share rules apply where Korean law governs — typically where the deceased was Korean or validly chose Korean law. Whether any forced share exists at all then depends on that governing law.

Can a gift the parent made years before death still count?

It can. A gift to a co-heir is in principle added to the base estate regardless of when it was made. A gift to someone who is not an heir is added only if it was made within one year before death, or where both sides knew it would harm a forced-share holder. Whether a particular transfer counts is judged by its substance rather than its label (Supreme Court decision of June 13, 2024, Case No. 2023Da304568).

How long do I have to bring a forced-share claim?

A claim lapses one year after the holder learns both that the inheritance has commenced and that there was a gift or bequest to be returned, and in any event ten years after the death — whichever comes first. For heirs living abroad, when the one-year period starts is itself often disputed.

If the will leaves me nothing, can I still receive a forced share?

Being disinherited by a will does not by itself remove a forced share. Testamentary freedom is limited by the forced share for those who qualify. How much, if anything, is actually recovered depends on the estate and the lifetime gifts, so each case needs individual review.
