Court and Ministry of Justice translation is a different discipline
Translating for a Thai court file is not general document translation with a stamp on it. The output has to be usable as evidence, which means it must be complete, must reproduce every seal, handwritten annotation and stamp as a described element rather than silently omitting it, and must render legal terms consistently with the Thai statutory vocabulary the judge already has in mind.
The Civil Procedure Code requires documents in a foreign language to be accompanied by a Thai translation, and the court may require the translator to certify it. In practice, the courts, the Ministry of Justice departments, the Legal Execution Department and the Department of Probation each have their own expectations about certification format and about who may sign.
A poor translation does not merely read badly. It creates argument. Rendering a foreign 'affidavit' as a Thai term implying sworn court testimony, or an English 'injunction' as a term used for a different provisional remedy under Thai procedure, hands the other side a submission about what the document actually is. Terminology discipline is the substance of this service, not a stylistic preference.
Document families we handle for Thai proceedings
| Document family | Typical receiving body | Certification pattern |
|---|---|---|
| Foreign judgments and orders | Civil Court, Central IP and IT Court | Certified translation plus legalised original from issuing state and Royal Thai Embassy |
| Powers of attorney executed abroad | All Thai courts | Notarised abroad, legalised, certified Thai translation |
| Corporate authority documents | Civil and Bankruptcy Courts | Certified translation of legalised certificate of incorporation and board resolution |
| Witness statements and expert reports | Trial bundle | Certified translation with bilingual glossary consistency across the bundle |
| Criminal record and probation documents | Department of Probation, Ministry of Justice | Certified Thai or English translation depending on direction of use |
| Enforcement documents | Legal Execution Department | Certified translation of title and asset documents |
How we control terminology across a bundle
Where a hearing involves live interpretation, the same glossary is handed to the interpreter. Nothing undermines a witness faster than the interpreter using a different Thai term for the contractual concept the whole bundle has defined one way.
- Glossary before translation: We extract every recurring legal and technical term and fix the Thai and English renderings with counsel before the first page is translated.
- Single-owner sections: Related documents stay with one translator so that a defined term does not shift between exhibits.
- Legal review: A Thai-qualified reviewer checks statutory references, court names and procedural terms against the Civil Procedure Code and the substantive statute in play.
- Certification and pagination: The bundle is certified, paginated to match the exhibit index, and delivered with a translator's declaration in the format the receiving body accepts.
Legalisation for documents crossing the border
A foreign document destined for a Thai court is legalised in the issuing country and then by the Royal Thai Embassy or Consulate there. A Thai court document destined for use abroad is translated, legalised by the Department of Consular Affairs of the Ministry of Foreign Affairs, and then legalised by the destination country's embassy in Bangkok. Thailand's accession to the HCCH Apostille Convention enters into force on 28 February 2027; before that date the embassy step remains mandatory in both directions.
Timing matters more than most litigants expect. MFA legalisation and embassy queues routinely consume two to three weeks combined, and courts do not extend hearing dates because a translation chain was started late. We plan the chain backwards from the hearing date and file the domestic exhibits while the foreign chain runs.
Common mistakes and how we avoid them
More questions we are asked
- Who may certify a translation for a Thai court?
- Practice varies by court. A translation company certification with translator details is commonly accepted; some matters require the translator to attend or to sign before an authorised officer.
- Does the court supply interpreters?
- Courts arrange interpreters for parties who need them, but parties frequently engage their own for technical or commercial matters and for pre-hearing preparation.
- Can LINE and email evidence be translated selectively?
- Selective translation invites an argument about context. Translate the full thread or agree the extract with the other side in advance.
- How is a foreign judgment used in Thailand?
- It is not directly enforceable. It is filed as evidence in a fresh Thai action on the underlying obligation, with full certified translation.
- What turnaround should I plan for a litigation bundle?
- Plan by page count and complexity rather than by a fixed figure, and add the MFA and embassy legalisation window on top for any foreign original.

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.
