Frequently asked · Sworn translation for Japan
Why does Japan only accept Sworn Translators for official Thai documents?
Japan requires every foreign-language civil, court, and educational document to be rendered by a 認証翻訳 + 公証人 registered with Notary Public + JLIA. Registrars, courts and immigration offices verify the translator's registration number before accepting the file — translations from generic agencies, Thai MOJ court interpreters, or Thai Notary Publics are rejected on submission.
How long does end-to-end sworn translation for Japan take from Bangkok?
Standard turnaround is แจ้งหลังตรวจเอกสาร. When the Japan embassy or consulate must legalise the source first, timing depends on its queue. We confirm the timeline and any urgent-handling fee after reviewing your documents.
What is the price range?
สอบถามเจ้าหน้าที่เพื่อขอใบเสนอราคา. Final quotation is confirmed after we inspect the scanned original — long court judgments (5–20 pages) and multi-column transcripts fall at the higher end.
How is a Japan Sworn Translator different from a Thai MOJ court translator?
A 認証翻訳 + 公証人 is registered with Notary Public + JLIA of Japan and carries a verifiable registration number in that jurisdiction. A Thai MOJ translator is registered with Thailand's Ministry of Justice and is only recognised inside Thai courts and Thai government offices — Japan authorities will not accept MOJ-only certification for the document types on this page.
Can I send documents from overseas? Do I need to visit your Bangkok office?
No visit required. Send high-resolution PDF scans via LINE Official @NYC168 or email contact@nyclegal.co.th. We return hard copies worldwide by EMS / DHL with tracking numbers. Overseas clients can pay by international wire or PayPal.
Do I still need MFA legalisation and embassy authentication before translation?
Usually yes. The Thai original is first legalised at the Department of Consular Affairs (MFA Chaeng Watthana / Chiang Mai / Songkhla / Khon Kaen), then authenticated by the Japan embassy or, for Hague Apostille member states, receives an Apostille stamp. Only then is the file forwarded to the sworn translator abroad. We handle every step end-to-end.

Frequently asked questions
- What makes a Thai translation 'certified' and who is allowed to certify it?
- A certified translation is a translation issued with a signed certification statement from a translation agency or qualified translator confirming the text is a true and complete rendering of the original. Thailand has no single government translator register for general use, so acceptance depends on the receiving authority: the Department of Consular Affairs accepts translations submitted with the original document for legalization, embassies usually accept agency-certified translations, and some foreign authorities additionally require a sworn or NAATI translator. We confirm the receiving body's rule before translating so the document is not rejected later.
- Do I need the original document or is a scan enough for translation?
- A clear scan is enough to produce the translation, but the original is normally required for the legalization step that follows. The Department of Consular Affairs checks the translation against the original or a certified true copy issued by the responsible Thai authority, so if you plan to legalize, send us a high-resolution scan to start the translation and keep the original ready for submission.
- How should Thai names be spelled in an English translation?
- Always match the spelling printed in the passport, even when it differs from Royal Thai General System transliteration. Authorities compare the translation against the passport and treat any mismatch as a different person, which is one of the most common causes of rejection. If a name has been spelled differently on older documents, we add a spelling-variation note or arrange a name-consistency affidavit.
- How long does a certified translation take and can it be rushed?
- Standard civil documents such as an ID card, house registration, birth or marriage certificate are typically ready in one to two working days, while contracts, court judgments and academic transcripts take longer because of terminology checks. Same-day handling is possible for short standard documents if the scan arrives in the morning; rush handling does not shorten the separate MFA legalization queue.
