When a relative dies in Texas and leaves a bank account in South Korea, or when you need to operate or close a Korean account from the United States, the bank will ask for US documents that carry an apostille. A Texas death certificate, heirship proof, or a power of attorney has no legal effect in South Korea until it is authenticated. This page explains how the apostille works and what a Korean bank generally expects.
What an apostille is
An apostille is a certificate that authenticates a public document — a notary's signature, a court seal, a registrar's certification — so it will be accepted by authorities in another country. For countries in the Hague Apostille Convention, the apostille is the finish line. For countries outside it, the same Texas certificate is the first step in a short legalization chain.
Does an apostille work in South Korea?
Yes. South Korea is a member of the Hague Apostille Convention, so a Texas document that carries an apostille from the Texas Secretary of State is accepted by Korean banks, government offices, and courts without consular legalization. Keep in mind that the apostille authenticates the document but does not translate it — your documents will still need a certified Korean translation before most institutions will process them.
How the Texas Secretary of State apostille works
Texas apostilles come from a single office: the Secretary of State's Authentications Unit in Austin. There is no county-clerk step — a document notarized by any Texas notary, in any of the 254 counties, goes straight to the state. Since October 2023 Texas issues one Universal Apostille (Form 2102) that works for every destination, whether or not the country belongs to the Hague Apostille Convention.
The state fee is $15 per document. Mailed requests can take up to 25 business days; in-person and appointment service in Austin is same-day for up to 10 documents, and a bulk drop-box handles larger batches in 24–48 hours. There is no online submission — every request is handled by mail or in person. Certified copies of vital records (birth, death, marriage, divorce) must be less than five years old.
Federal documents — FBI background checks, USCIS naturalization certificates, IRS letters — cannot be apostilled by Texas; they go to the U.S. Department of State. We confirm the correct authority before anything is filed, so your documents are never rejected on a technicality.
Claiming or operating a South Korean bank account from the US
Korean banks restrict a deceased account holder's account once they learn of the death, and they will not release the funds until the heirs are properly documented. Because Korea maintains detailed family-relation registries for its own nationals, banks are accustomed to verifying heirship through official records; for a US-based family, apostilled US documents fill that role. The apostilled US death certificate proves the death, and apostilled birth or marriage certificates — together with any heirship or estate documents from the Texas side — establish who the heirs are.
If you cannot travel to Korea, an apostilled power of attorney allows a lawyer or trusted representative there to submit the bank's forms, receive the funds, and close the account on your behalf. The same approach works for operating an existing account from abroad: banks generally require identity and authority documents to be apostilled and translated before they will act on instructions from a foreign-resident customer or representative.
Every bank applies its own claim forms, verification steps, and thresholds, and requirements can differ between institutions and branches. Confirm the exact checklist with the bank before you start, and order several apostilled copies of key documents so the bank and any other Korean office can each hold one.
Documents you'll need
- Apostilled US death certificate (multiple original copies recommended)
- Proof of relationship and heirship (birth or marriage certificates and estate documents, apostilled)
- Official ID of each claiming heir
- An apostilled power of attorney to a representative in South Korea, if you cannot appear in person
- Any inheritance documentation the bank specifies under Korean law
- The bank's own claim forms, per its instructions
Translation
Once your US documents are apostilled, they must receive a certified Korean translation before Korean banks and government offices will accept them. Complete the apostille first and the translation second, because the translator normally renders the apostille certificate along with the document itself. Allow extra time for this step; it is separate from the apostille and can add several days to the overall timeline.

A note on accuracy
Apostille and legalization requirements change, and each receiving institution — a foreign land registry, bank, pension office, or consulate — can impose its own rules. This article reflects requirements verified in 2026 and is general information, not legal advice.
