As South Korea continues to attract foreign entrepreneurs, executives, and long-term residents, an increasing number of expatriates and multi-nationality families are discovering that their estate and trust structures, often established under foreign law, do not comply with Korea’s civil-law inheritance system and Korean inheritance and tax laws.
When a family member passes, the combination of Korean statutory succession laws, foreign wills, offshore trusts, and cross-border assets can give rise to complex legal conflicts, international tax complexities, and unexpected disputes. Proactive estate planning is therefore essential to prevent litigation, ensure wishes are met, avoid unnecessary taxes, and expedite asset transfers.

Korean Cross-Border Estate & Trust Planning
Korea’s Inheritance Law Framework
Korea follows a civil-law, forced-heirship system under the Korean Civil Act. This means that statutory heirs, including spouses, children, parents, and other lineal relatives, are entitled to a mandatory statutory share (yuhun bun) in all but the most exceptional cases. Regardless of a will, a spouse and children cannot be disinherited entirely in most cases. Importantly, Korean law applies to the estate of a decedent who was domiciled in Korea at death unless a valid foreign choice-of-law clause applies and to Korean nationals (with exceptions in certain situations). Carefully structuring wills and trusts is essential to avoid disputes and minimize tax obligations.

Recognition of Foreign Wills and Trusts in Korea
Korea lacks a domestic trust tradition comparable to Anglo-American trust law. While Korea enacted a Trust Act in 1961, its scope and use remain limited to certain commercial and financial arrangements. Traditional private or family trusts such as those established in the U.S., UK, or offshore jurisdictions (e.g., Singapore, Bermuda, BVI, Jersey) are not automatically recognized under Korean inheritance law and procedures.
Korean courts may recognize foreign trusts when they meet the requirements of Korea’s Private International Law. The Act on Private International Law of Korea (2022 Amendment) permits the application of foreign law when a trust or will is properly governed by a foreign jurisdiction. However, in most cases, Korean real estate and domestic financial assets remain subject to local Korean law, even if the decedent had a foreign trust.
Trust and Inheritance-Related Disputes in Korea
IPG Legal has observed an increase in litigation in Korea and abroad involving cross-border estate structures with a Korean nexus. Typical scenarios include:
- Trustee Control Disputes: Korean heirs challenge the validity of offshore trustees managing Korean assets.
- Asset-Transfer Challenges: Korean courts scrutinize transfers of property to offshore trusts as potential “fraudulent conveyances.”
- Dual-Probate/Inheritance Conflicts: Executors appointed in Australia, the U.S., the UK, etc., face parallel probate/inheritance procedures in Korea for assets located in Korea.
- Recognition of Foreign Judgments: Beneficiaries attempt to enforce foreign trust or probate orders in Korean courts, often facing public policy objections.
- Korean Mandatory Statutory Shares: A foreign will or trust is partially negated due to Korea’s statutory share mandates.
- Scrutiny by Korean Courts of Pre-Death Transfers: Courts in Korea and the Korean National Tax Service are auditing pre-death transfers that may run in conflict with Korea’s Mandatory Statutory Share Law and Korean Tax Law.
Therefore, cross-border estate planning for foreigners in Korea and multi-national families should consider:
- Choice of Law Clauses under Korea’s Private International Law Act specifying which country’s law governs succession.
- Tax Coordination: Korean inheritance tax applies in many cases to the global assets of Korean residents and nationals, with rates of up to 50%. Double taxation may arise unless a treaty (e.g., Korea-U.S. or Korea-UK tax treaty) provides relief.
- Dual Wills: foreign residents, in some cases, should prepare a local Korean will (for domestic assets) and a foreign will (for overseas assets) that complement each other rather than conflict.
- Trust Disclosure and Compliance: where applicable, ensure trustees and beneficiaries meet Korean reporting and foreign-asset declaration obligations.
- Comprehensive Estate Audit: identify Korean-situs and foreign-situs assets, applicable laws, and potential heir claims.
- Maintain transparent documentation to help avoid later invalidation claims by Korean heirs.
- Forced-heirship challenges: proactively structure gifts and trust distributions, etc., consistent with Korean Law.
