The Authentifier cheat sheet
We get it, the language around what we do is super confusing. In Dubai they like the term ‘attestation’. In Thailand it’s ‘authentication’. In other places it’s a bit of both. Authentication. Attestation. Legalisation. What do all these different terms mean? Here’s our cheat sheet for Authentifier terminology.
Attestation
An official verification of something as true or authentic (Merriam-Webster).
In the Authentifier process, attestation refers to the notarial certification of documents. However, the word attestation is commonly used in the UAE and Qatar interchangeably with the term ‘authentication’. We try to use region-specific language on our site to ensure that users who have been told they need a document attested are getting the information they are looking for, so in some areas of this site, the terms ‘authentication’ and ‘attestation’ are used interchangeably.
For more on the attestation process and what it means for you, read our companion article, What Does Attestation Mean?
Authentication
An act, process, or method of showing something (such as an identity[…]) to be real, true, or genuine : the act or process of authenticating something (Merriam-Webster).
You may require documents to be authenticated for use overseas. In the Authentifier process, authentication refers to getting documents legally authenticated by the Department of Foreign Affairs and Trade (DFAT). Having documents approved by DFAT is compulsory for many documents needed overseas, in particular for countries like Thailand, the UAE, and Qatar.
Authentication is also the preferred terminology in Thailand, so is used in areas of this site in place of ‘attestation‘, to ensure it is understood.
Authentifier
This word doesn’t exist in English, which is exactly why we chose it! We liked the French version of ‘authenticate’ and have been using it as our business name for years. It works well for us largely because it can be separated from all the other confusing terminology, so our clients know exactly who we are.
Legalisation
To make legal; to give legal validity or sanction to (Merriam-Webster).
Documents needed for some overseas countries (i.e. for the UAE, Qatar or Thailand) need to be legalised by the relevant foreign embassy in Australia to officially attest the notorised and authenticated documents.
