Apostille for South Korea
By John F. Heinz, Managing Director, Prismark Signature Services
Published: August 7, 2026
Quick Answer
If you are using a U.S. public document in South Korea, the Korean authority or organization receiving it may require an apostille. South Korea and the United States participate in the Hague Apostille Convention, so qualifying U.S. public documents can generally be authenticated with an apostille rather than additional Korean consular legalization.
The document must first be properly issued, certified, or notarized for its type. The correct apostille authority depends on where and by whom the document was issued. The Korean receiving authority determines which documents, translations, and supporting materials are required for your particular matter, so those requirements should be confirmed before processing begins.
Key Takeaways
- South Korea accepts Hague Apostilles for qualifying U.S. public documents.
- U.S. documents with the appropriate apostille generally do not require additional authentication by a Korean consulate.
- California vital records generally should be official certified copies suitable for apostille.
- Court records generally require official certified court copies.
- Federal documents follow the federal apostille process rather than the California process.
- Translation requirements depend on the Korean authority or organization receiving the document.

Common Documents Apostilled for Use in South Korea
Documents commonly apostilled for use in South Korea include birth certificates, marriage certificates, death certificates, divorce decrees, court orders, powers of attorney, adoption records, diplomas, college transcripts, school records, corporate documents, and criminal background checks.
These documents may be requested for family matters, education, employment, business transactions, corporate matters, inheritance, property matters, or other official purposes. The specific documents required are determined by the Korean authority or organization handling your matter.
Do I Need a Certified Copy?
For many government-issued records, yes. California birth, marriage, and death records should generally be official certified copies suitable for apostille. Court records generally require official certified court copies. A regular photocopy or unofficial printout is not a substitute for an appropriately issued, certified, or notarized public document.
Educational, corporate, and privately signed documents may require different preparation. The appropriate document should be identified before the apostille process begins.
State Apostille or Federal Apostille?
The correct apostille authority depends on who issued the document. California public documents are generally authenticated through the California Secretary of State once properly prepared. Documents issued by another state generally follow that state’s apostille process, while documents issued by U.S. federal agencies generally follow the federal apostille process.
For example, an FBI background check is a federal document and follows the federal apostille process through the U.S. Department of State rather than the California Secretary of State.
Educational Documents for South Korea
Educational records are a common category of U.S. documents apostilled for use in South Korea. The Consulate General of the Republic of Korea in Los Angeles specifically notes that California university records requiring authentication for use in Korea should obtain the appropriate California apostille rather than consular document confirmation.
Diplomas, transcripts, and other school records can require different preparation depending on how the document was issued. Prismark can review the educational document and determine the appropriate preparation and apostille path without turning the process into a do-it-yourself procedure.
Do My Documents Need a Korean Translation?
Some U.S. documents used in South Korea may need to be translated into Korean, but there is no single translation rule that applies to every document or every purpose. The Korean authority or organization receiving the document determines whether a translation is required and what form of translation it will accept.
Clients should confirm those requirements before arranging translation. If translation is required, Prismark can coordinate professional Korean translation services through our trusted translation partners.
An Apostille Does Not Guarantee Acceptance
An apostille authenticates the signature of the public official, the capacity in which that person acted, and, when appropriate, the seal or stamp on the public document. It does not validate the contents of the document or determine whether the document satisfies a particular Korean legal, administrative, educational, or business requirement.
A properly apostilled document may therefore still be subject to separate requirements imposed by the Korean authority or organization receiving it.
