My document type is not listed. Can you still help?

Usually yes. Send the document and the instruction from the authority that requested it. The chain of certification depends on who issued the document and who will receive it, not on a fixed catalogue, so unusual documents are assessed individually before a plan and a fee are proposed.

Do you handle electronic documents and e-signatures?

Where the receiving authority accepts them, yes. Thailand recognises electronic signatures under its electronic transactions legislation, but many foreign registries and embassies still require a wet-ink original with physical seals. The accepted format should be confirmed in writing before work begins.

What if the destination changes its requirements mid-process?

We re-check requirements close to the filing date for exactly that reason, and if they change we set out the revised steps and any additional cost before continuing. Documents already certified can often be reused in the new chain, which limits the impact.

Sworn Translation for Korea — Official Legalization from Bangkok

NYC Legal & Notary Services Co., Ltd. provides end-to-end sworn translation for documents destined for Korea. Our workflow covers Thai source preparation, Notary Public + MFA + Apostille (28 February 2027), coordination with Notary Public + affidavit, and international courier delivery. Every sworn translator in our network is officially registered and every deliverable is fully traceable.

Competent authority in Korea

Notary Public + affidavit. Primary reference: https://www.moj.go.kr/. Documents translated by a sworn translator registered with this authority carry legal status equivalent to the original and can be submitted directly to courts, ministries, civil registries, universities and local government offices in Korea without further authentication. Sworn translations must be produced in-country by a locally-registered translator.

Effect of the Hague Apostille (28 February 2027) on the chain to Korea

From 28 February 2027 Thailand is a party to the Hague Apostille Convention. Thai original documents destined for Korea now require only an Apostille from the Department of Consular Affairs (Chaeng Watthana), removing the destination-embassy step entirely. The workflow shortens from four stages (Notary → MFA → Embassy → Sworn) to three (Notary → MFA Apostille → Sworn), saving both time and fees significantly.

Documents commonly submitted

Birth, marriage, divorce and death certificates for family and estate matters; university diplomas and transcripts for study abroad and professional licensing; police clearance certificates for residency and citizenship applications; powers of attorney and single-status affidavits for real-estate and marriage registration; company documents and board resolutions for subsidiary incorporation and branch registration; court judgments and legal documents for cross-border enforcement.

Five-step workflow

1) Free consultation and document review; 2) Preliminary English translation by NYC Legal team; 3) Notary Public + MFA Apostille (28 February 2027); 4) Dispatch to sworn translator registered with Notary Public + affidavit; 5) Return delivery by DHL/FedEx to Thailand or direct courier to destination authority in Korea.

Pricing and turnaround

Full-package pricing (Notary + MFA + Apostille + sworn translator + courier) is quoted after document review per standard document (birth/marriage certificate) and quoted on request for complex documents (court judgments, contracts over 20 pages). Standard turnaround: 10–14 business days. Express Service: 5–7 business days (+50% fee).

FAQ

Q: How long is a sworn translation for Korea valid?

A: Translations do not technically expire, but destination authorities usually require documents dated within 6 months for visa filings and 3 months for marriage registration. The registered authority is Notary Public + affidavit.

Q: Do I need originals or are copies acceptable?

A: Wet-ink originals are always required — sworn translator seals and signatures are physical stamps. NYC Legal returns originals via tracked international courier.

Q: Does Korea accept a Thai Notary + MFA Apostille directly, or must I also get a sworn translation?

A: The Apostille certifies the original and the issuing officer's signature but does not cover translation. If the destination language differs from Thai/English, a sworn translation is always required.

Q: How can I place an order?

A: Book via LINE @nyclegal, call +66 2 254 8757, email contact@nyclegal.co.th, or visit our office at 88/8 Sirinrat Building, Floor 2, Wireless Rd, Lumphini, Pathumwan, Bangkok 10330 (BTS Ploenchit).

Q7343. Does Korea accept sworn translations prepared in Thailand?
Only with a locally sworn translator at destination. The registry authority in Korea is Notary Public + affidavit. Thailand deposited its instrument of accession to the Hague Apostille Convention on 30 June 2026 and it enters into force on 28 February 2027; until then the destination embassy step still applies.

Detailed questions & answers

Does Korea accept a Thai certified translation instead of a local sworn translator?

Korea's sworn-translator registry is held by Notary Public + affidavit. A local sworn translator is normally required; origin-country translations alone are usually refused. Recognition is not reciprocal, so plan an extra local step. Receiving-authority rules change; confirm with that authority before you file. Source: https://www.moj.go.kr/

Does Korea require a sworn translator?

Korea maintains its sworn-translator register through Notary Public + affidavit. Translation is generally expected to be produced by a sworn translator registered in the destination country. Source: https://www.moj.go.kr/

What legalisation steps does a Thai document need for use in Korea?

The Thai legalisation chain is: translation → notary or issuing authority → MFA Department of Consular Affairs → the destination country's embassy or consulate in Thailand. Thailand deposited its Hague Apostille accession on 30 June 2026 and it enters into force on 28 February 2027; before that date the destination-embassy step still applies.

How do I use a Korea document in Thailand?

Thai authorities normally ask for a fresh Thai translation prepared in Thailand and legalised by the MFA Department of Consular Affairs. A Thai-language translation is required by most Thai authorities even when the original is in English.

How long does a Korea translation package take?

Timing depends on page count and the queue at each legalising authority. We pre-check the source file, match name spelling to the passport, produce the translation, run the MFA step and coordinate the destination embassy end to end. We quote every job in writing before work starts and bill government fees at cost.
