Certified translation, accepted the first time.
Certified translation is required whenever an official body — a court, embassy, ministry or university — needs assurance that a translation faithfully reflects the original. Othello provides certified EN↔TH translation with a signed certification of accuracy, and manages the full notarisation and legalization chain when documents must be used abroad.
- 01Visa, immigration & residency applications
- 02Marriage, birth, death & civil-registry documents
- 03Academic transcripts, diplomas & credentials
- 04Corporate, court & regulatory documents
- 05Any document for a government body or embassy
The whole chain, under one workflow.
A certified translation is often just the first step. For overseas use, documents need notarial attestation, MFA legalization and — since Thailand is not a Hague Apostille country — embassy authentication.

What applicants ask.
The questions raised on certified documents — click any to expand.
01Is your certification accepted by embassies and the MFA?+
Yes. Our certification of accuracy on Othello letterhead meets the standard the MFA, embassies and government bodies require, and we prepare translations to their formatting expectations.
02Can you handle legalization as well as translation?+
We manage the complete chain — certified translation, notarial attestation, MFA legalization and embassy authentication — so your document arrives ready to submit.
03Why is there no apostille?+
Thailand is not a party to the Hague Apostille Convention, so an apostille is not available — embassy legalization replaces it. We map the exact steps for your destination.
04Do you match my passport spelling?+
Always. We use the exact spelling from your passport across every document to avoid mismatches that cause rejection.
05How fast is it?+
A single certified document is often ready within one working day; legalization steps add a few days depending on service level. We confirm the total with your quote.
