Korean Family Law: Inheritance and Estate Planning — A Complete Guide for Foreign Nationals
When a loved one passes away in Korea — or when a Korean resident or citizen dies leaving assets abroad — navigating the inheritance process can be overwhelming, especially for foreign nationals unfamiliar with Korean civil law. Korea's inheritance system is governed primarily by the Civil Act (민법, Act No. 471), and it contains specific rules about who inherits, in what order, and in what proportions. This comprehensive guide explains how Korean inheritance law works, what foreign nationals must know, and how to plan your estate effectively under Korean jurisdiction.
1. Legal Framework: The Korean Civil Act on Succession
Korean succession law is codified in Part V (Inheritance) of the Civil Act, covering Articles 997 through 1118. The law distinguishes between two types of succession:
- Statutory (intestate) succession – When a person dies without a valid will, the Civil Act prescribes exactly who inherits and how much.
- Testamentary succession – When a valid will exists, the deceased's wishes govern distribution, subject to the mandatory minimum share (유류분, yuryu-bun) rules.
Korea follows a universal succession principle: heirs inherit both assets and debts of the deceased. This is a crucial point — heirs can find themselves liable for debts they did not know about unless they take affirmative steps to limit their liability.
2. Order of Heirs Under Korean Law
Article 1000 of the Civil Act establishes a strict priority order for heirs:
- First priority: Lineal descendants (children, grandchildren)
- Second priority: Lineal ascendants (parents, grandparents)
- Third priority: Siblings
- Fourth priority: Collateral relatives up to the 4th degree
The surviving spouse is treated specially under Article 1003: the spouse inherits concurrently with either first or second priority heirs, receiving an additional 50% of what a lineal heir receives. If there are no lineal descendants or ascendants, the spouse inherits the entire estate.
3. Statutory Inheritance Shares
When multiple heirs are present, the estate is divided according to statutory shares:
- Children inherit equally. A child from a previous marriage has the same rights as a child from the current marriage.
- Spouse receives 1.5 shares compared to each child (e.g., spouse + 2 children = spouse gets 3/7, each child gets 2/7).
- Adopted children have identical rights to biological children under Korean law.
- Illegitimate children recognized under Article 855 have equal inheritance rights following a 2005 Constitutional Court ruling.
4. Wills in Korea: Requirements and Types
For a will to be legally valid in Korea, it must conform to one of five recognized forms under Articles 1065–1070 of the Civil Act:
- Holographic will (자필증서유언): Entirely handwritten, signed, and dated by the testator — no typewritten portions are allowed.
- Notarial will (공정증서유언): Dictated to a notary public in the presence of two witnesses; most legally secure.
- Secret will (비밀증서유언): Written and sealed by the testator, then presented to a notary and two witnesses.
- Recorded will (녹음유언): Audio recording of the testator's voice with witness identification.
- Sealed written will (구수증서유언): For emergency situations when the testator cannot use other forms.
Wills must be probated (검인) at the family court before execution, except notarial wills. The probate process confirms authenticity but does not validate the legal sufficiency of the will's content.
5. Mandatory Minimum Share (유류분, Yuryu-bun)
Even with a valid will, certain close relatives are guaranteed a minimum share of the estate under Articles 1112–1118. This is called yuryu-bun:
- Lineal descendants and spouse: 1/2 of their statutory share
- Lineal ascendants and siblings: 1/3 of their statutory share
If a will deprives an heir of this minimum, that heir may file a yuryu-bun deficiency claim (유류분반환청구소송) within one year of learning of the deficiency, or within ten years of the estate opening. In 2023, the Constitutional Court ruled that sibling yuryu-bun rights were unconstitutional, and the National Assembly subsequently revised the law — siblings no longer have yuryu-bun rights as of 2024.
6. Renouncing or Limiting Inheritance
Because heirs inherit debts as well as assets, Korean law provides two protective mechanisms:
- Full renunciation (상속포기): The heir completely withdraws from the inheritance. Must be filed with the family court within 3 months of learning of the estate opening (Article 1019).
- Limited acceptance (한정승인): The heir accepts the estate but limits liability for debts to the value of inherited assets. Also filed within 3 months (with extensions possible in certain cases).
If the deadline passes without action, the heir is deemed to have accepted the estate unconditionally — including all debts. This catches many foreign heirs off guard.
7. Korean Inheritance Tax
Korea imposes one of the highest inheritance taxes in the OECD under the Inheritance Tax and Gift Tax Act (상속세 및 증여세법). Key points:
- Tax rates: Progressive from 10% (estates under KRW 100 million) to 50% (estates over KRW 3 billion)
- Basic deduction: KRW 500 million for general heirs; spouses may deduct up to KRW 3 billion (or the actual inherited amount, whichever is less)
- Filing deadline: 6 months from the date of death (9 months if the deceased was domiciled abroad)
- Late filing incurs a 20% surcharge plus interest
For foreign nationals inheriting Korean assets or Korean nationals with overseas assets, double taxation treaties may apply. Korea has inheritance/gift tax treaties with the United States, France, and a few other countries.
8. International Aspects: Which Country's Law Applies?
When the deceased was a foreigner or held assets in multiple countries, private international law (국제사법) determines which country's law governs. Under Korea's Private International Law Act (국제사법):
- Succession to movable property is governed by the law of the deceased's last domicile.
- Succession to immovable property (real estate) in Korea is governed by Korean law regardless of the deceased's nationality.
This means foreign nationals owning real estate in Korea will always have that property governed by Korean inheritance law. Estate planning should account for this rule.
9. Estate Planning Strategies Under Korean Law
For foreigners with Korean assets or family members, proactive estate planning is essential:
- Draft a notarial will in Korea to ensure clarity and speed of probate.
- Consider lifetime gifts (증여) — subject to gift tax, but may be more tax-efficient with proper planning.
- Use family corporations to hold assets and facilitate smoother succession.
- Coordinate with advisors in both countries when the estate spans multiple jurisdictions.
- Document all assets and debts to prevent heirs from unknowingly incurring liability.
10. Division of Inherited Property (분할협의)
Even after the estate vests in multiple heirs, they co-own it as tenants-in-common (공유상속). To divide the estate, heirs must reach a partition agreement (분할협의). If agreement is impossible, any heir may petition the family court for a judicial partition (Article 1013).
Real estate inherited by multiple heirs cannot be individually sold or mortgaged without co-owner consent, creating practical complications that early planning can avoid.
Frequently Asked Questions (FAQ)
Q1. Can a foreigner inherit property in Korea?
Yes. Foreign nationals can inherit Korean real estate and other assets. However, certain foreign exchange reporting requirements under the Foreign Exchange Transactions Act apply when transferring inherited funds abroad. You must also comply with Korean inheritance tax obligations.
Q2. My Korean spouse died without a will. What are my inheritance rights?
As the surviving spouse, you inherit concurrently with the deceased's children. If the deceased had two children, you receive 3/7 of the estate and each child receives 2/7. If there are no children or parents, you inherit the entire estate. Your share is protected regardless of your nationality.
Q3. How long does the Korean inheritance process take?
Simple estates with a clear will and cooperative heirs can be resolved in 3–6 months. Contested estates or complex cross-border situations may take 1–3 years or longer if litigation is involved.
Q4. What is the difference between renunciation and limited acceptance?
Full renunciation means you inherit nothing — not assets, not debts. Limited acceptance means you inherit assets and debts, but your personal liability for debts is capped at the value of the assets you inherited. Both must be filed within 3 months of learning of the estate opening.
Q5. My Korean parent left a will disinheriting me. Can I challenge it?
If you are a child or spouse of the deceased, you are entitled to a yuryu-bun (mandatory minimum share) of 1/2 your statutory share. You can file a yuryu-bun deficiency claim in Korean court within one year of discovering the infringement, up to a maximum of ten years from the estate opening.
Q6. Do I need to file Korean inheritance tax even if I live abroad?
Yes, if you inherit Korean-sited assets (real estate, shares in Korean companies, bank accounts in Korean banks), you are subject to Korean inheritance tax. The filing deadline is 9 months from death if the deceased was domiciled outside Korea.
Q7. Can I write a will in English for Korean assets?
A foreign-language will can be recognized in Korea under certain conditions, but a Korean notarial will is strongly recommended for Korean assets to avoid complications during probate. If you use a foreign will, it may need to be translated and authenticated before Korean courts will accept it.

📋 韩国法律洞察 | 家庭法与继承
作者：律师 NOH UJIN | HANBYOL LAW LLC，首尔
韩国家庭法：继承与遗产规划——外国人完全指南
当亲人在韩国去世，或韩国居民、公民去世后留有海外资产时，对于不熟悉韩国民法的外国人来说，继承程序可能令人不知所措。韩国的继承制度主要由《民法》（民法，第471号法令）管辖，其中包含关于谁继承、继承顺序以及继承比例的具体规定。本综合指南解释了韩国继承法的运作方式、外国人必须了解的内容，以及如何在韩国法律管辖下有效规划遗产。
1. 法律框架：韩国民法中的继承规定
韩国继承法规定于《民法》第五编（继承），涵盖第997条至第1118条。法律区分两种继承类型：
- 法定继承（无遗嘱继承）：当人在没有有效遗嘱的情况下去世时，民法规定确切的继承人及继承份额。
- 遗嘱继承：当存在有效遗嘱时，由死者的意愿决定财产分配，但需遵守强制最低份额（유류분）规则。
韩国遵循概括继承原则：继承人同时继承死者的资产和债务。这是关键一点——继承人可能因不知道的债务而承担责任，除非主动采取措施限制其责任。
2. 韩国法律下的继承人顺序
民法第1000条规定了继承人的严格优先顺序：
- 第一顺位：直系卑亲属（子女、孙子女）
- 第二顺位：直系尊亲属（父母、祖父母）
- 第三顺位：兄弟姐妹
- 第四顺位：四亲等以内的旁系亲属
根据第1003条，配偶享有特殊待遇：配偶与第一或第二顺位继承人共同继承，获得直系继承人份额的1.5倍。如果没有直系卑亲属或尊亲属，配偶继承全部遗产。
3. 法定继承份额
当有多个继承人时，遗产按法定份额分配：
- 子女平等继承。前婚子女与现婚子女具有相同权利。
- 配偶获得1.5份（例如配偶+2名子女：配偶获3/7，每个子女获2/7）。
- 根据韩国法律，养子女与亲生子女享有同等权利。
4. 韩国遗嘱的要求和形式
在韩国，遗嘱要具有法律效力，必须符合民法第1065-1070条规定的五种认可形式之一：
- 自书遗嘱：由立遗嘱人完全手写、签名并注明日期——不允许有打印内容。
- 公证遗嘱：在两名证人在场的情况下向公证人口述；法律保障最为充分。
- 秘密遗嘱：由立遗嘱人书写并密封，然后在公证人和两名证人面前提交。
- 录音遗嘱：立遗嘱人声音的音频录制，包含证人身份确认。
- 封缄书面遗嘱：用于立遗嘱人无法使用其他形式的紧急情况。
5. 强制最低份额（유류분，유류분）
即使有有效遗嘱，根据第1112-1118条，某些近亲属也被保证继承遗产的最低份额，称为유류분：
- 直系卑亲属和配偶：法定份额的1/2
- 直系尊亲属：法定份额的1/3
2024年修订后，兄弟姐妹不再享有유류분权利。
6. 放弃或限制继承
由于继承人同时继承债务，韩国法律提供两种保护机制：
- 完全放弃（상속포기）：继承人完全退出继承。须在得知继承开始后3个月内向家事法院申请。
- 限定承认（한정승인）：继承人接受遗产，但对债务的个人责任限于所继承资产的价值。也需在3个月内申请。
7. 韩国遗产税
韩国依据《继承税及赠与税法》征收OECD中最高的遗产税之一：
- 税率：从10%（遗产不足1亿韩元）到50%（遗产超过30亿韩元）
- 基本扣除：一般继承人5亿韩元；配偶最多可扣除30亿韩元
- 申报截止期：死亡之日起6个月（如死者居住在海外则为9个月）
常见问题（FAQ）
问1：外国人能在韩国继承房产吗？
可以。外国人可以继承韩国房产和其他资产。但将继承资金转移到海外时，需要遵守《外汇交易法》下的外汇申报要求，同时还需履行韩国遗产税义务。
问2：我的韩国配偶没有留下遗嘱就去世了，我的继承权如何？
作为在世配偶，您与死者子女共同继承。如死者有两个子女，您获得3/7，每个子女获得2/7。如果没有子女或父母，您继承全部遗产。
问3：遗嘱中有一部分剥夺了我的继承权，我可以提出异议吗？
如果您是死者的子女或配偶，您有权获得유류분（强制最低份额），即法定份额的1/2。您可以在发现侵权后一年内提起유류분返还请求诉讼，最迟不超过继承开始后十年。
问4：住在海外是否需要申报韩国遗产税？
是的，如果您继承了韩国境内的资产（房产、韩国公司股份、韩国银行账户），则须缴纳韩国遗产税。如果死者居住在韩国境外，申报截止期为死亡后9个月。
问5：我可以用英文为韩国资产立遗嘱吗？
外语遗嘱在某些条件下可以在韩国获得认可，但强烈建议对韩国资产使用韩国公证遗嘱，以避免遗嘱认证过程中的复杂情况。

Derecho de Familia en Corea: Herencia y Planificación Patrimonial — Guía Completa para Extranjeros
Cuando un ser querido fallece en Corea —o cuando un residente o ciudadano coreano muere dejando bienes en el extranjero— navegar el proceso de herencia puede ser abrumador, especialmente para los extranjeros no familiarizados con el derecho civil coreano. El sistema de herencias de Corea está regulado principalmente por el Código Civil (민법, Ley N.° 471), que contiene reglas específicas sobre quién hereda, en qué orden y en qué proporciones.
1. Marco Legal: El Código Civil Coreano sobre Sucesiones
El derecho sucesorio coreano está codificado en la Parte V (Herencia) del Código Civil, artículos 997 a 1118. La ley distingue entre sucesión intestada (sin testamento) y sucesión testamentaria. Corea sigue el principio de sucesión universal: los herederos heredan tanto los activos como las deudas del fallecido.
2. Orden de Herederos
- Primera prioridad: Descendientes en línea directa (hijos, nietos)
- Segunda prioridad: Ascendientes en línea directa (padres, abuelos)
- Tercera prioridad: Hermanos y hermanas
- Cuarta prioridad: Parientes colaterales hasta el 4.° grado
El cónyuge supérstite hereda junto con los herederos de primera o segunda prioridad, recibiendo un 50% adicional respecto a cada heredero de línea directa.
3. Cuotas de Herencia Legal
- Los hijos heredan a partes iguales.
- El cónyuge recibe 1,5 cuotas en comparación con cada hijo (ej.: cónyuge + 2 hijos = cónyuge 3/7, cada hijo 2/7).
- Los hijos adoptivos tienen los mismos derechos que los hijos biológicos.
4. Testamentos en Corea
Para que un testamento sea legalmente válido debe adoptar una de cinco formas reconocidas: testamento ológrafo (totalmente manuscrito), testamento notarial (la forma más segura), testamento secreto, testamento grabado y testamento oral de emergencia.
5. Legítima (유류분)
Los descendientes directos y el cónyuge tienen derecho a una legítima del 50% de su cuota legal, incluso si el testamento los excluye. Tras la reforma de 2024, los hermanos ya no tienen derechos de legítima.
6. Renuncia y Aceptación Limitada
- Renuncia total: El heredero se retira completamente. Debe solicitarse dentro de los 3 meses posteriores a conocer la apertura de la herencia.
- Aceptación limitada: El heredero acepta la herencia pero limita su responsabilidad por deudas al valor de los activos heredados.
7. Impuesto de Sucesiones en Corea
- Tipos impositivos: Del 10% (patrimonios inferiores a 100 millones de KRW) al 50% (superiores a 3.000 millones de KRW)
- Deducción básica: 500 millones KRW (herederos generales); hasta 3.000 millones KRW (cónyuge)
- Plazo de declaración: 6 meses desde el fallecimiento (9 meses si el fallecido residía en el extranjero)
Preguntas Frecuentes (FAQ)
P1. ¿Puede un extranjero heredar bienes inmuebles en Corea?
Sí. Los extranjeros pueden heredar bienes inmuebles y otros activos en Corea, sujetos a las obligaciones fiscales y de control de cambios aplicables.
P2. Mi cónyuge coreano falleció sin testamento. ¿Cuáles son mis derechos?
Como cónyuge supérstite, hereda junto a los hijos del fallecido. Si hay 2 hijos, usted recibe 3/7 y cada hijo 2/7. Si no hay hijos ni ascendientes, usted hereda la totalidad.
P3. Un testamento me ha excluido de la herencia. ¿Puedo impugnarlo?
Si es hijo o cónyuge del fallecido, tiene derecho a una legítima equivalente al 50% de su cuota legal. Puede interponer una demanda de deficiencia de legítima en un año desde que tuvo conocimiento de la infracción.
P4. Vivo en el extranjero. ¿Debo declarar el impuesto de sucesiones coreano?
Sí, si hereda activos situados en Corea. El plazo de declaración es de 9 meses desde el fallecimiento si el causante residía fuera de Corea.
P5. ¿Puedo redactar un testamento en español para bienes en Corea?
Un testamento en idioma extranjero puede ser reconocido bajo ciertas condiciones, pero se recomienda encarecidamente otorgar un testamento notarial coreano para bienes en Corea.
