Certified Translation

Most delays in "Certified Translation" matters come from re-filing, not from the work itself. Our Certified Document Translation team therefore verifies destination requirements first and only then walks the file through the accepted sequence. We handle files from Bangkok, upcountry, and overseas clients working through a power of attorney. Every matter has one named owner, with a Notarial Services Attorney (registered with the Lawyers Council of Thailand) performing the final certification review before release. The written quote lists the professional fee, official government rates with no markup, and shipping at cost — no hidden extras — under either a standard 5-7 business day or a rush 1-3 business day schedule.

Certified Translation: common pitfalls and how to avoid them

Originals outside the validity window — many destinations require documents issued within 3-6 months. Confirm with the receiving authority first.
Dates that disagree across documents — this must be fixed at the issuing agency; it cannot be corrected at the translation stage.
Using a translator without an official seal — the MFA and embassies will not accept it, and the chain restarts.
Submitting an uncertified photocopy instead of the original — the receiving office will not review it and you rejoin the queue.
