Certified vs. Notarized Translations in Australia: What’s the Difference?

A confusion among all migrants moving to Australia is whether to get their official documents certified or notarized. While many use the terms interchangeably, the processes are completely different, and each of them has a different purpose. 

Certified vs. notarized translations in Australia are something you must know if you are migrating to the country. It will save you from document rejections, expensive submissions, and processing delays.

Here, we will clear the air around these and also help you understand when you should choose what, so that you don’t have a problem with the processes.

Key Takeaways: The Difference between Certified and Notarized Translation

  • Certified translations verify the accuracy of translation, while notarized translations verify the identity of the translator
  • Most Australian immigration, education, and government applications need certified translations
  • Notarized translations are mostly needed for international legal or official use
  • Certified translations are generally faster, cheaper, and required more commonly
  • It is necessary to check the receiving authority’s requirements to avoid delays or rejections

What Is a Certified Translation in Australia?

Certified translations are those where a professional translator provides a signed statement confirming that the translation is a true and accurate representation of the original document. In Australia, the National Accreditation Authority for Translators and Interpreters accredits translators. 

Therefore, if you need a certified translation, you must hire a NAATI translator. Once the translator completes a translation, they attach a certification statement that includes: 

  • Their NAATI Certification number
  • A declaration that says the translation is true and accurate
  • Their signature and date of translation
  • The language pair (source and target language)

The certification acts as a confirmation that a qualified professional has confirmed the accuracy of the translation. Certified translations are accepted by Australian government departments, courts, universities, and professional bodies that need official submissions.

What Is a Notarized Translation?

Notarized translations are the ones that are authenticated by a notary public. In this case, the notary verifies the identity of the translator and adds an official anti-fraud seal to the document. The role of the notary in this type of translation is: 

  • Verify the identity
  • Witness the signature of the translator
  • Put their notarial seal and signature on the document

The notary public does not check or verify the quality of the translation, but they confirm that the person doing it is a translator, and they swear to the accuracy of their work under oath. The objective is to add legal weight to the document, thus making it acceptable for various purposes. 

All notarized translations have these key components: 

  • The completely translated document
  • The translator’s signed certificate statement
  • Official seal and signature of the notary public
  • A certificate confirming the authentication process
  • Date and location of notarization

That helps you understand what each of these terms means and what you need to look for in each of them. The following section will answer the main question of the discussion: certified vs notarized translations in Australia.

Certified vs. Notarized Translations in Australia: The Key Differences

The key difference between the two is that a certified translation guarantees the accuracy of the text and completeness of the translation and includes a signed statement from the translator. On the other hand, notarized translation adds a legal layer to the translated document where a notary public verifies the identity of the translator signing the document, but does not verify the linguistic quality. 

Here’s a look at certified translation vs notarised translation:

Feature Certified Translation Notarized Translation
Primary Guarantee Completeness and accuracy of the translated text The translator’s identity and the act of signing an oath
Who Performs It Qualified translators with proper credentials Government-authorised notary public
Purpose To prove that the translated piece matches the original source perfectly To remove fraud and swear to the document’s validity before an official, legally
Common Uses Academic transcripts, birth certificates, and standard immigration documents Specific court cases, international contracts, and overseas legal proceedings
Cost and Time Faster and cheaper Requires additional costs and steps

While that explains how these are different from one another, you might still wonder when you need a certified and when you need a translation notarized. Let’s explain them one by one in the following sections.

When Do You Need a Certified Translation in Australia?
