Apostille vs Notarization in Korea
Foreign diplomas, birth certificates, and bank letters often need more than a plain translation. Korea may ask for certified translation, notarization (공증), apostille, or embassy legalization, sometimes more than one. This guide clarifies which path fits common visa, ARC, and Study in Korea cases.

Three paths people mix up
- Certified translation. A qualified translator or licensed administrative agent attests the Korean/English rendering is accurate.
- Notarized translation. A notary verifies the translator’s identity/signature (공증). Common for court, overseas, or strict receiving offices.
- Apostille. An authentication under the Hague Convention so a public document is recognized abroad (or a foreign public document is recognized in Korea). Not the same as translation.
When you typically need which
| Situation | Common requirement |
|---|---|
| Immigration / ARC foreign docs | Certified or notarized translation |
| University admission from abroad | Apostille (or embassy legalization) + translation |
| Using a Korean document overseas | Apostille via the correct Korean authority |
| Non-Hague country documents | Consular legalization instead of apostille |
HezoKorea reviews your receiving office’s rules before you pay for the wrong stack of stamps, see apostille Korea, certified translation, and notarized translation.
Usual order of steps
- Confirm what the university, immigration office, or embassy listed on their checklist.
- Obtain or renew the original public document.
- Complete apostille / legalization in the issuing country when required.
- Arrange translation (and notarization if required) into the language the Korean office accepts.
Tip: Doing translation before apostille (or the reverse) can force a redo. Share your checklist with us first.
Frequently asked questions
Is an apostille a translation?
No. An apostille authenticates the origin of a public document. You often still need a separate certified or notarized translation for Korean offices.
Can HezoKorea handle both?
Yes. We coordinate translation, notarization guidance, and apostille/legalization pathways for the same document package.
