Certified vs. Notarized Translation: Which Do You Need?

A clear legal breakdown of the differences between certified and notarized translations, and how to know which one your receiving institution demands.

1. What is a Certified Translation?

A certified translation is a word-for-word translation accompanied by a formal signed Certificate of Accuracy asserting that the translation is complete and that the linguist is competent in both languages. USCIS requires certified translations.

2. What is a Notarized Translation?

A notarized translation includes a commissioned notary public witnessing the translator's signature and stamping the certificate with an official notarial jurat and seal.

3. When is Notarization Required?

Notarization is typically required for state DMV driver license conversions, certain local state court filings, international apostille applications, and foreign embassy visa dossiers.
