Certified Document Translation in Thailand — Complete Guide

Short answer first

Before translating anything, confirm what the receiving authority accepts: a translator's certification, a Ministry of Foreign Affairs legalized translation, an embassy-legalized set, or a NAATI-stamped translation for Australia. Choosing the wrong level is the single most common reason a file is sent back. Send scans first and we will confirm the required format, wording and order of certification.

Overall timeline: 3–7 business days for a standard set, longer when MFA or embassy legalization follows

Pitfalls and how to avoid them

Name spelled differently across documents

Prevention: Use the passport spelling everywhere and translate any name-change certificate as supporting evidence.

Translating only part of a multi-page document

Prevention: House registrations and transcripts must be translated in full, including pages that only carry a seal.

Low-quality scans

Prevention: Send high-resolution colour scans so the Garuda emblem and signatures are legible.

Advice from real cases

Order the whole set at once — batching keeps terminology identical and is faster than piecemeal orders.
Keep a digital copy of every certified translation; renewals and later applications often reuse them.
Ask us before paying for legalization you may not need for that particular recipient.
