Ansim Sangsok: South Korea's Asset Discovery Service for Heirs
Ansim Sangsok: South Korea's Asset Discovery Service for Heirs
One of the hardest problems for overseas heirs is finding out what the deceased actually owned — and owed — in South Korea. Bank accounts you did not know existed, insurance policies, real estate, pension entitlements, tax liabilities. The Korean government's answer to this is the Ansim Sangsok (안심상속 원스톱서비스), or Safe Inheritance One-Stop Service, a consolidated search that scans up to 20 categories of assets and liabilities across government databases.
What Ansim Sangsok Searches
A single application checks:
- Bank deposits, savings, and outstanding loans
- Insurance policies and pension entitlements
- Real estate holdings (land and registered buildings)
- Investment securities
- Tax liabilities owed to national and local authorities
- Vehicle registrations
The results give heirs a comprehensive picture of the estate's assets and debts — critical information for deciding whether to accept the inheritance, renounce it, or file for qualified acceptance within the three-month deadline.
The One-Year Deadline
The application must be filed within one year of the date of death. After this window closes, the service is permanently barred. There are no extensions. This is not a filing penalty situation — the service simply becomes unavailable, and heirs must then search for assets institution by institution.
How to Apply
In person: Visit a local community center (eup, myeon, or dong office) or Gu office. This is the most practical option for heirs who are physically in South Korea.
Online: Through the Government24 portal (gov.kr). However, online applications require Korean digital credentials that foreign nationals typically do not have — a Korean phone number, a digital certificate, or a verified account.
Financial accounts specifically: If the online portal is not accessible, financial asset verification can also be done through a physical application to the Financial Supervisory Service (FSS).

Documents Needed
To establish legal standing as an heir and submit the Ansim Sangsok application, you need:
- Death certificate of the deceased
- Family Relationship Certificate (Detailed version) for the deceased
- Proof of the applicant's relationship to the deceased (if foreign-issued, documents must be notarized and apostilled)
- Applicant's ID (passport, ARC)
For overseas heirs not registered on a Korean Family Relations Register, proving the relationship requires apostilled foreign birth or marriage certificates plus certified Korean translations.
For Overseas Heirs Who Cannot Travel
If you cannot come to South Korea, the Ansim Sangsok application can be submitted through a local representative holding a notarized and apostilled Special Power of Attorney. The POA must specifically authorize the representative to file estate-related government inquiries on your behalf.
Alternatively, the FSS pathway for financial assets can sometimes be initiated through a Korean law firm without the heir being physically present.
Why This Matters
Without Ansim Sangsok, heirs are essentially guessing about the estate's composition. The risk is not just missing assets — it is missing debts. If the estate is insolvent and heirs fail to renounce within three months (because they did not know about the debts), they automatically assume personal liability for 100% of the deceased's obligations.
Run the Ansim Sangsok search as early as possible. The South Korea Expat Death Guide includes the complete Ansim Sangsok application workflow, the documents required for each scenario, and a step-by-step guide for overseas heirs using a POA.
