A good share of the confusion in this subject is not procedural. It is linguistic. Somebody is holding a checklist from a British university that says the document must be legalised, an email from a Dubai employer that says it must be attested, and advice from a relative who says they just got an apostille and it was fine. All three are talking about the same underlying act, and the disagreement is in the vocabulary rather than in the requirement.
So here is the vocabulary, laid out once.
The act itself
Underneath all the words there is one thing happening: an official is confirming that a signature or a seal already on a document is genuine. Not that the contents are true — nobody in this chain reads your marriage certificate and forms a view about your marriage. Only that the person who signed it was who they said they were, and had the authority they claimed.
Every term below is a name for performing that act, or for a particular authority performing it.
Legalisation
The generic term, and the one most European and Commonwealth authorities use. If a form says a document must be legalised, it is asking for official confirmation of the signature or seal on it. The form frequently does not say by whom, which is where the trouble starts: legalised by your own foreign ministry is a different amount of work from legalised by the receiving country’s embassy.
You will see the spelling legalization just as often. Same word, different side of the Atlantic.
Attestation
The word the UAE and the wider Gulf use for the same act. UAE authorities, employers and licensing bodies say attestation almost without exception, and so does MOFA’s own material. If your checklist says legalisation and you are dealing with Dubai, read attestation and nothing changes.
It is also used slightly more loosely than legalisation, to mean the whole chain rather than one link — “get your degree attested” usually means all four or five steps, not just the last one.
Apostille
A specific, simplified form of legalisation, agreed between the countries that have joined the Hague Apostille Convention. One standardised certificate, issued by a designated authority, replaces the chain of stamps — but only between member countries.
The most useful way to hold it: an apostille is a kind of legalisation, not an alternative to it. Which also explains why it does not work everywhere. The convention is an agreement to accept each other’s certificates, so it only helps when both ends are inside it.
The UAE is not a party to the convention, which is why apostilles come up constantly in Dubai and never finish the job. We have written separately on apostille versus attestation and on which documents are and are not apostilled.
Consularisation
The embassy or consulate step, named after who does it. Shipping and trade paperwork is often described this way — a certificate of origin needing consularisation means the destination country’s mission has to stamp it. It is one link in the chain, not a different chain.
Authentication
Mostly American usage, and occasionally a trap, because it is used both for the act in general and for a specific certificate issued where the apostille route does not apply. If a US-issued document is going to a non-member country such as the UAE, what the issuing office provides is not an apostille, and the form may well call it something else entirely. Read what the certificate on the page actually says rather than what you expected it to say.
Notarisation
Not the same act, and worth keeping separate. A notary attests a signature, or certifies that a copy matches an original. That is an act performed on the document, which then needs confirming by someone else — so notarisation is frequently step one of a chain rather than a stage of it.
The practical rule: documents an authority issued already carry an official seal, so they skip the notary. Documents you or your company wrote — a power of attorney, a board resolution, an affidavit, an agreement — have no official seal at all until a notary puts one there, and nothing further in the chain will touch them before that happens.
Certified, sworn, official, legal: the translation words
A separate family of terms, and they belong to a separate question. Attestation asks whether the document is genuine. Translation asks what it says. Mixing the two produces the most expensive mistake in this field, which is a document translated before the stamps were added, so that the translation does not show them.
In the UAE the term that matters is a translation produced by a translator licensed by the Ministry of Justice. Elsewhere you will meet sworn translator, certified translation, official translation and court translator, which are not interchangeable between countries even though they sound it. If a foreign authority asks for a sworn translation, ask them whether a UAE MOJ-licensed translation satisfies it, because sometimes it does and sometimes they insist on one of their own.
How to read a checklist written in the wrong vocabulary
Three questions turn any of these words into something actionable:
- Which authority has to perform the act? Your foreign ministry, or the receiving country’s mission, or both, in which order.
- Which country issued the document? That is where the chain starts, regardless of where you live or what passport you hold.
- Does the receiving authority also want a translation, and whose? Ask before anything is translated, not after.
Get those three in writing from whoever is going to receive the document, and the words stop mattering. Our attestation services page sets out the chain in both directions, and the legal translation that follows is done here by MOJ-licensed translators who translate every stamp as well as the text.

Frequently asked questions
Are legalisation and attestation the same thing?
In practice, yes. They describe the same act — an official confirming that a signature or seal on a document is genuine — and which word you meet depends on who wrote the form. British and European authorities tend to say legalisation. UAE and wider Gulf authorities say attestation. If a UK office tells you a document must be legalised and a Dubai office tells you it must be attested, nobody is asking for two different things.
Is an apostille a kind of legalisation?
Yes, and that is the clearest way to hold it in your head. An apostille is a simplified form of legalisation agreed between the countries that joined the Hague Apostille Convention: one certificate instead of a chain. It is not a different category of act, just a shorter route to the same end — and the route is only open between member countries.
What is consularisation?
The embassy or consulate step, named after who performs it. Trade and shipping documents are often described as needing consularisation, which means the destination country’s mission has to stamp them. It is one link in the chain rather than an alternative to it.
Is notarisation part of attestation?
It is often the first step of it, but it is a different act. A notary attests a signature or certifies a copy — usually on a document nobody official issued, like a power of attorney or an agreement. Attestation then confirms the notary’s seal. Documents issued by an authority in the first place normally skip the notary, because they already carry an official seal.
Why do people say MOFA and MOFAIC?
They are the same ministry. The formal name is the Ministry of Foreign Affairs and International Cooperation, so you will see MOFA, MoFAIC and the full name used interchangeably, including on official material. Nothing turns on which one appears on your checklist.
What should I do when two checklists use different words?
Ask the authority that will actually receive the document to describe what they need as a list of steps rather than as a single word. “The document must carry the UAE embassy stamp and MOFA attestation” is unambiguous. “The document must be legalised” is not, because it does not say by whom. Getting that in writing is worth more than any glossary.
