What's the Difference Between a Certified and a Regular Translation?

09 August 2026

I hear this question almost every day — usually from a client who had a translation done by themselves or someone they know, then found out the institution wouldn't accept it. The difference is simpler than it sounds, but the consequences are serious. Confusing the two can lead to a loss of time and money.

What Is a Regular Translation

Anyone fluent in a language can translate any text. Even if the language is accurate, this translation carries no official validity. A translation done by a friend or by translation software, however technically correct, falls into this category. It's enough for personal use, but not for official processes.

What Is a Certified Translation

A certified translation is done by a translator who has taken an oath before a notary, formalised with an official record. The translator applies their own stamp and signature to the translation, legally taking responsibility for its accuracy. Without that signature and stamp, no official institution will accept it.

Why This Difference Matters So Much

For official processes — visa applications, university enrolment, marriage procedures, court proceedings — institutions care not only about the translation's accuracy but about 'who did it, and under what authority.' A sworn translator's signature provides that assurance. So it's not just about language, but about official responsibility.

The Confusion Between Certified Translation and Notarisation

These two are frequently confused but are separate steps. Certified translation is the translator taking responsibility for accuracy with their own signature and stamp. Notarisation is the notary confirming that the signature genuinely belongs to that translator — an additional layer. Some institutions accept certified translation alone, others also require notarisation.

A Real Example

A client, applying to a university abroad, had their diploma translated by a friend with good English. The translation was linguistically flawless — but the university didn't accept it, because it lacked a sworn translator's signature and stamp. In the end they had to have the document re-translated from scratch, certified, and this delayed the application process by weeks. The lesson: for a document going to an official place, the translation's accuracy alone isn't enough — its official validity is essential too.

Frequently Asked

'My English is very good — can I translate my own document?' — For official processes, no; the institution wants a translation by an independent, authorised third party, and you can't translate your own document. 'Is certified translation the same in every country?' — No, the system varies from country to country; in some a 'sworn translator' applies, in others a notarised translation. 'Can I translate with Google Translate and have a sworn translator certify it?' — A sworn translator does the translation under their own responsibility, checking it themselves; they don't blindly certify a ready machine translation.
