Certified vs. Sworn Translation: Which Do You Need?

Publicado a 10 de julho de 2026 · 6 min de leitura

If you're applying for a visa, a university place, or registering a marriage abroad, someone has probably told you to get an "official translation" — without telling you which kind. The difference matters: submit the wrong type and many authorities will simply reject your file.

Certified translation: the accuracy statement

A certified translation comes with a signed statement from the translator or agency confirming that the translation is complete and accurate, usually with a stamp and date. It's the standard requirement in most English-speaking countries — USCIS in the United States, UK universities, Canadian immigration — and for many university admissions worldwide.

Key characteristics:

  • Produced by a qualified translator; no court registration required
  • Includes a signed certificate of accuracy
  • Usually delivered as a stamped PDF; hard copy on request
  • Faster and cheaper than sworn translation

Sworn translation: legal validity by appointment

A sworn translation is produced by a translator who has been officially appointed by a court or government body — a traducteur assermenté in France, traductor jurado in Spain, beeidigter Übersetzer in Germany, yeminli tercüman in Turkey. Their stamp gives the document legal validity by itself.

Civil-law countries typically demand sworn translations for:

  • Birth, marriage and death certificates in visa or naturalization files
  • Court documents and notarial deeds
  • Commercial-register extracts for company formation
  • Diplomas for state-regulated professions

The quick decision rule

  1. Submitting in the US, UK, Ireland, Canada, Australia? Certified is almost always enough.
  2. Submitting to an authority in France, Spain, Germany, Italy, Turkey, or most of continental Europe? Expect to need a sworn translation.
  3. The receiving office mentioned an apostille or notary? You likely need a notarized translation on top — ask them to confirm in writing.

When in doubt, ask the receiving authority one precise question: "Do you require a translation by a court-sworn translator, or is a translator's certificate of accuracy sufficient?" Their answer removes all guesswork.
