These three terms are often mixed up, but they are separate steps. For a translation, each one builds on the one before. Knowing the difference helps you ask for exactly what the receiving organisation needs.
Certified translation
The translator signs a statement confirming that the translation is accurate. GOV.UK visa guidance says a certified translation must include that confirmation, the date of the translation, the translator’s full name and signature, and their contact details. Most UK organisations ask for this, and often nothing more.
Notarised translation
A notary public certifies the translator’s declaration and signature. Some organisations ask for this extra step, particularly when a document will be used abroad.
Apostille
An apostille is issued by the FCDO Legalisation Office. It confirms the signature or seal of a UK public official, such as a notary, so that a document can be used in countries that belong to the Hague Apostille Convention. It does not confirm what the document says. For a translation, this usually means notarisation first and the apostille after. Countries outside the Convention may need consular legalisation through their embassy instead.
Apostille fees and timing
You, or your notary, apply to the FCDO Legalisation Office online. GOV.UK currently lists £45 per document for a paper apostille, plus postage or courier, and shows the current processing time when you apply. An e-Apostille costs £35 and takes up to two working days, but it is only for PDF documents signed electronically by a UK notary or solicitor, and it is not available for every document.
Which one do you need?
That is decided by whoever will receive the document, not by the translator. Before you order, ask the receiving authority, or your adviser, exactly what they need. When more than one step is needed, they happen in this order:
- Certified translation, signed by the translator
- Notarisation, if it is asked for
- Apostille, or consular legalisation, if the authority abroad asks for it
Common questions
Can you notarise my translation?
I am a translator, not a notary. When a notarised translation is needed, I can arrange it with a notary public and pass on the notary’s fee at cost, quoted in advance.
Does the Home Office ask for notarised translations?
For UK visa and immigration applications, the published guidance asks for a certified translation with the translator’s details, and does not mention notarisation. Notarisation is mostly needed for documents going abroad, or when an organisation asks for it.
Does an apostille prove the translation is correct?
No. An apostille confirms the signature or seal of the UK official on the document, such as the notary. It does not check or confirm what the document or the translation says.
