Need Official Documents Translated for Overseas Use?

Certified translation for overseas use and formal notarization in Korea solve two different problems, and getting the sequence wrong is the most common way to waste a trip. This office holds both the certified-translator license that most Korean institutions accept directly and routine experience walking clients through the notarization, apostille, and consular-confirmation steps that follow when a document needs to go further.

Translation Certificate vs. Translation Notarization — Which One Do You Actually Need?

Two different documents both get called "certified translation" in everyday conversation, and mixing them up costs time and money.

• 번역확인증명서 (Certificate of Translation) — issued only by a nationally licensed 외국어번역행정사 (certified public translator), under Administrative Agent Act (행정사법) Article 20(2). The translator both translates and certifies the translation matches the original in one step. It's accepted directly at Korean public institutions and schools, immigration offices, HRD Korea (Q-net), the Korea Software Industry Association (KOSA), and the National Health Personnel Licensing Examination Board — no notary office or attorney involved, and Article 2 of the same Act means a Korean administrative agency cannot refuse a licensed translator's certificate for its own paperwork.
• 번역공증 (Translation Notarization) — a notary public (or notarial law office) witnesses the translator's sworn statement that the translation is accurate and certifies that the statement was made; the notary is not vouching for translation quality, only that the translator swore to it. This is the version foreign institutions, embassies, and apostille applications require, and it costs more (translation fee plus a separate per-page notarization fee, roughly double a Korean-only document) because two professionals — the translator and the notary — are involved instead of one.

Rule of thumb: submitting to a domestic Korean institution → a translation certificate is enough, and it's faster and cheaper. Submitting overseas, to an embassy, or anywhere an apostille is required → you need translation notarization, since a translator's own certificate isn't itself apostille-eligible.

Notarization, Broken Down: Four Different Procedures Called "공증"

"공증" gets used as a catch-all, but it covers four distinct procedures with different evidentiary purposes, different required documents, and different costs.

1. Translation notarization (번역공증) — the notary witnesses the translator's sworn statement of accuracy. Requires a qualified translator (their ID, seal, and proof of translator credentials — license or degree/experience certificate) plus the original and the translation. Needed for visa, immigration, and study-abroad filings going to a foreign institution.

2. Fact notarization (사실공증) — the document's author appears before a notary and confirms, on the record, that its contents are true and that they personally signed or sealed it — turning an ordinary private document (parental consent letters, financial guarantees, powers of attorney, contracts, sworn statements, board resolutions) into something with much stronger evidentiary weight, including, for money or property matters, eventual eligibility for compulsory enforcement (e.g., auction) without a separate lawsuit. In person, bring ID, your seal, the original document, and — critically — your seal certificate (인감증명서) issued within the last 3 months; by proxy, add a notarization power of attorney sealed with your registered seal, the agent's ID, and (for a company) the corporate seal certificate and registry certificate, both within 3 months.

3. Signature notarization (서명공증) — a narrower version of fact notarization: the notary confirms only that a signature is genuinely yours, not the full content of the document. Common for English-language documents foreign institutions and embassies request — powers of attorney, letters of authorization. In practice it's usually processed together with fact notarization, and the signature should be made in front of the notary rather than pre-signed.

4. Certified-copy notarization (사본공증/원본대조공증) — the notary compares a copy against the original in hand and certifies they're identical, for documents you can't safely surrender (diplomas, degree certificates, ISO certificates, business registration certificates, family register copies, employment certificates) but need to submit to more than one place. It's the lightest-weight of the four — no signature or content review, just identity confirmation — but the original must be physically present, or it can't be done at all.

Apostille, Consular Confirmation, or Neither?

Once a document (or its notarized translation) needs to be recognized abroad, which authentication path applies depends entirely on whether Korea and the destination country are both members of the Apostille Convention.

• Apostille — for the 120+ member countries (the US, most of Europe, and, as of its 2023 accession, China), a single certification from Korea is recognized directly, with no destination-country embassy visit required. In Korea, apostilles for both public documents and notarized private documents are issued at the Overseas Koreans Agency (재외동포청) integrated public service center (Twin Tree Tower A, 15F, 6 Yulgok-ro, Jongno-gu, Seoul; 02-6747-0404) — which shares a building with the Ministry of Justice's own counter, so confirm which queue ticket you're pulling.
• Consular confirmation — for the roughly 70 non-member countries (Vietnam and Thailand among them), the same document needs Ministry of Foreign Affairs confirmation and then a visit to that country's embassy or consulate in Korea for a final stamp — the same underlying paperwork, but with an extra stop and longer turnaround.
• Neither applies to a small set of destination countries that recognize a certified translator's own certificate directly, without any authentication layer at all — worth confirming with the receiving institution before paying for authentication you don't need.

What actually qualifies. Only public documents (issued by a government body, or an institution operating under delegated government authority — e.g., a medical device manufacturing/import certificate, a factory registration certificate, a direct-production certificate, a CSAT score report, HACCP or GMP certification) or notarized private documents are eligible in the first place — an unnotarized private document can't get either an apostille or consular confirmation on its own.

Corporate Document Translation: Registry Certificates & Articles of Incorporation

Two corporate documents come up constantly for overseas bank accounts, foreign investment, and cross-border contracts — and neither has an official government-issued English version, so a certified translator's rendering is the only option a receiving institution will accept.

Registry certificate (등기사항전부증명서) — renamed from "법인 등기부 등본" in 2011, this is the company's legal identity card: company name, registered head office and change history, registration number, incorporation date, par value and authorized/issued share counts by class, paid-in capital, the business purposes stated in the articles of incorporation, and the current inside directors, representative director, and their appointment/reappointment dates. Because no official English version exists, the translation must precisely mirror the Supreme Court registry's own format and terminology, keep the original Korean alongside the translator's certification, and add an apostille if the destination requires one.

Articles of incorporation (정관) — translated by legal function, not word-for-word, keeping the chapter/article structure (Chapter → Article → Clause) intact and one English term fixed per Korean concept throughout (e.g., 이사회 always "Board of Directors," 대표이사 always "Representative Director" — never swapped for "Managing Director" or "CEO" mid-document). A recent live example: three documents — registry certificate, articles of incorporation, and an electronic financial business registration certificate — translated and notarized together for a Canadian submission, with translation and original bound together at notarization to establish reliability for the receiving institution.

When the destination isn't an Apostille member. Thailand is a useful example: since Thailand isn't a Convention signatory, an English articles of incorporation can't go the apostille route at all — it has to be notarized, then confirmed by Korea's Ministry of Foreign Affairs, then confirmed again at the Royal Thai Embassy in Seoul, in that exact order.

Personal & Family Document Translation

Minor travel consent. A child traveling internationally without both parents — with only one parent, or with a third party such as a relative or group leader — needs a parental consent letter plus a family relation certificate proving the signer is actually the parent, both translated and backed by a translation certificate. The Philippines, Vietnam, Guam/Saipan, and much of Europe request this at immigration without warning; arriving without it can mean a lengthy hold or outright refused entry.

Naturalization certificate. A US citizen (or other 외국국적동포 — someone who held Korean nationality at birth and later naturalized elsewhere) filing a domestic residence report (거소신고) — which unlocks smoother immigration, real estate, banking, foreign-exchange, health insurance, and veteran-benefit processing in Korea — must submit their naturalization certificate together with a Korean translation, alongside the passport, detailed 기본증명서, residence-report application, proof of residence, and an employment declaration/restricted-occupation non-employment pledge.

Family Relation Certificates — Which Version to Request

Korea's family relation registry issues five certificate types (family relation, basic, marriage relation, adoption relation, and step-child adoption relation), each now available as a general, detailed, or specific certificate to limit how much personal history gets exposed. A general marriage-relation certificate for someone who remarried shows only the current marriage; the detailed version shows every past marriage and divorce; the specific version shows only whichever past record the requester designates. When an institution asks for a family relation certificate, requesting the specific version (rather than defaulting to detailed) keeps unrelated personal history off the document.

Beyond Translation: Fact-Confirmation Certificates & Other Administrative Filings

As a licensed 행정사, this office's authority under Administrative Agent Act Articles 2 and 20 extends past translation into drafting and certifying facts more broadly — three services come up often enough to be worth flagging separately from the core translation practice:

• Call-recording transcripts (녹취록) and fact-confirmation certificates. A recording made by a party to the conversation is generally admissible as evidence without the other side's consent (a non-party recording without consent is not — it's treated as unlawful wiretapping). A transcript's evidentiary weight depends on clearly documented date/time/location and audio clarity, and courts give more weight to a transcript prepared by an independent professional — an administrative agent or stenography office — than a self-prepared one; under Article 20, a 행정사 can also issue a fact-confirmation certificate for the underlying recording alongside the transcript itself.
• Name change (개명) petitions. Filed at the applicant's registered domicile, address, or current residence's local government office (or online via the courts' e-litigation portal, or through the Overseas Koreans family registry office for Koreans living abroad) — basic certificate, family relation certificates for both parents (and adult children's, if any), resident registration copy, and supporting evidence for the reason and the intended new name. Adults typically take 3–4 months; minors 2–3 months, and a minor's petition needs both parents jointly (or the sole custodial parent, with the other spouse's power of attorney if filing alone).
• Lease registration order (임차권등기명령). For a tenant whose lease has ended but whose deposit hasn't been returned — filing this at the district court covering the leased property preserves the tenant's existing priority repayment right and right to assert the lease against a new owner (대항력/우선변제권) even after the tenant moves out, which would otherwise lapse the moment they vacate. The Supreme Court has held the landlord's deposit-return obligation must be performed before the tenant's registration-cancellation obligation, not simultaneously (2005다4529).

How the Translation Process Works

1. Tell us the document type and destination (country and receiving institution) so we know whether a translation certificate or full notarization applies.
2. Send a scan of the original to [email protected] — a phone photo sent first is fine to get translation started sooner.
3. We review the finished translation together against five details before finalizing: your name and its exact English spelling/spacing as it appears on your passport, date of birth, registered address, mailing address (if different), and phone number.
4. Bring the original in person when picking up the notarized set, or mail it in.
5. If mailed in, we scan and email the finished notarized set as a PDF and post the physical copies to your address.
