Certified vs. Notarized Translations: What Is the Difference?

“Do I need a certified translation or a notarized one?” This is, by far, one of the most frequent questions we receive from clients. And rightly so: the two terms sound similar, are often used interchangeably, and the institutions requesting the documents rarely explain the difference. Choosing wrong means wasted time, repeated trips and, sometimes, rejected applications.

In this article, we explain in plain language what certified translations are, what notarized translations are, when you need each one, and how you can handle everything through a single partner.

What is a certified translation?

A certified translation (also known in Romania as an authorized or sworn translation) is a translation performed by a translator authorized by the Romanian Ministry of Justice. The translator applies their stamp and signature to the document, together with a certification statement attesting to the accuracy of the translation — officially taking responsibility that the translation faithfully reflects the original document.

The elements that make a translation “certified”:

• It is performed by a translator authorized by the Ministry of Justice for that language pair
• It bears the stamp and signature of the authorized translator
• It includes the certification statement attesting the accuracy of the translation

A certified translation is sufficient in many situations: employment files, documents for universities, papers submitted to certain public institutions, technical or commercial documentation for business partners.

What is a notarized translation?

A notarized translation is a certified translation that goes one step further: the authorized translator’s signature is legalized by a notary public. In practice, the notary does not verify the translation itself, but officially confirms that the signature on the document belongs to an authorized translator registered with the notary office.

In other words: every notarized translation is first a certified translation, but not every certified translation is notarized. Notarization is an additional layer of official validation, required by institutions where the stakes of the document are higher.

Important to know: for notarization, the notary usually requires the original document or a legalized copy of it to be presented. That is why it is essential to know from the very beginning which type of translation is required — so you can prepare the correct documents in a single trip.

When do you need each type of translation?

A certified translation is usually sufficient for: CVs and employment files for private companies, commercial documents between business partners, manuals and technical data sheets, official correspondence, admission files for some universities.

A notarized translation is frequently required for: civil status documents (birth, marriage, death certificates), education documents submitted to state institutions, documents for courts and legal proceedings, vehicle registration documents, notarial documents (powers of attorney, declarations, contracts), citizenship, residency, or visa applications.

The practical rule: always ask the institution requesting your document which type of translation it accepts. And if the document is going abroad, you may need one extra step — the apostille.

Bonus: what about the apostille?

For documents used outside Romania (or foreign documents used in Romania), many countries that are signatories to the Hague Convention require an apostille — an additional certification applied by the competent authorities (the Prefecture, the Chamber of Notaries Public, or the Court, depending on the type of document), which confirms the authenticity of the document at international level.

So the complete chain, for a high-stakes document going abroad, can look like this: certified translation → notarization → apostille. Sounds complicated? That is exactly why it is easier to work with an agency that handles the entire chain, from translation to apostille, without you having to run between the translator, the notary office, and the prefecture. We will cover the Hague Apostille in detail in a future article.

Common mistakes that cost you time and money

• Requesting a simple translation when the institution requires a notarized one — your application gets rejected and you start the process all over again.
• Paying for notarization when it was not necessary — additional notary costs with no benefit whatsoever.
• Not bringing the original document to the notarization — the notary cannot legalize the signature, and the trip was wasted.
• Translating from a non-conforming copy — some institutions require the translation to be made from the original or from a legalized copy.
• Leaving everything to the last minute — notarization and apostille procedures involve institutions with their own schedules; nobody will change your deadline.
