Sworn / Court-Certified Translation

Sworn, certified, notarised: three different things

Continental Europe uses sworn translators appointed by a court or ministry, whose signature alone gives the translation legal force. Common-law jurisdictions such as the United Kingdom, Ireland, the United States, Canada and Australia have no sworn register at all; they rely on a certified translation with a signed statement of accuracy, sometimes plus a notarial or affidavit layer. Thailand sits in between: the Ministry of Foreign Affairs Legalisation Division does not appoint sworn translators, it verifies the signature on a translation and stamps the pairing of source and translation.

The practical consequence is that the correct product is defined by the receiving authority, never by the sending country. A German Standesamt wants a beeidigter Übersetzer. A Spanish consulate wants a traductor jurado listed by the MAEC. A US university wants a certified translation on letterhead. Ordering the wrong tier is expensive because the fix usually means starting the whole legalisation chain again.

Destination matrix we work to

Formatting rules that decide acceptance

• Mirror the source layout: a translation that reflows a two-column certificate into prose is routinely refused by European registrars.
• Transcribe every seal, stamp, watermark and handwritten annotation inside square brackets rather than describing them loosely.
• Never translate a proper name; transliterate and add the original script in parentheses on first appearance.
• Leave illegible passages marked as illegible instead of inferring content, then attach a note stating what could not be read.
• Keep the source and translation physically bound with a ribbon and overlapping seal where the destination expects it, which is standard for Italy and Spain.

Turnaround planning

Translation itself is rarely the bottleneck. The chain is. A typical Thai civil document bound for a European consulate spends one to three working days in translation, two to five working days at the Ministry of Foreign Affairs depending on whether you use the express counter, and anything from same-day to three weeks at the mission, which is where the variance lives. We plan backwards from your appointment date and tell you the last safe start date rather than quoting only the translation step.

Common mistakes and how we avoid them

More questions we are asked

Can a translation sworn in Thailand be used directly in Spain?

Not on its own. Spain generally requires a traductor jurado on the MAEC list, or a Thai translation whose translator signature has been verified by the Thai MFA and then legalised by the Spanish consulate. We confirm which of the two the receiving office wants before starting.

Is a sworn translation valid forever?

The translation does not expire, but many authorities impose a freshness rule on the underlying civil-status extract, commonly three or six months. Plan the extract, not the translation, around your appointment.

Who signs when two languages are involved, for example Thai to Italian?

One practitioner qualified in the exact pair signs. We do not relay through English for legalised work because the consulate legalises the signature of the person attesting the Thai text.

What happens if the consulate rejects the format?

We reformat and resubmit at our cost when the defect is ours. Where the mission changes its own published format mid-chain, we document the change and re-run the affected step.

Do you translate documents issued outside Thailand?

Yes, but a foreign-issued document normally needs authentication in its country of origin before Thai legalisation, so we sequence that step first.
