Certified vs Notarised Translation for UK Documents

You have Chinese documents to submit in the UK and somebody — a forum, an agency, a relative — has told you they must be notarised. For the usual UK recipients, the certified vs notarised translation question has a fairly settled answer: a spouse or student visa, a university, the NHS, the DVLA and the UK courts ask for a certified translation, and a notary adds a layer none of them requested. Notarisation and an apostille answer a different question altogether, and one of them cannot be applied to a Chinese-issued document in Britain at all. What almost every UK submission needs is a certified translation, which I produce as an ITI-certified Chinese-to-English translator — signed, dated, normally back within 24 hours.

What the UK rules say

Certified. gov.uk sets the bar in one sentence: you “ask the translator to confirm in writing on the translation” that it is “a true and accurate translation of the original document”, “the date of the translation” and “their full name and contact details”. The Institute of Translation and Interpreting says the same in its own words — “To certify a translation, the translator must attest that the translation is a true, complete and accurate translation of the original document” — and adds that each page “should be stamped and/or initialled… to prevent any tampering or misuse”. Appendix FM-SE, the specified-evidence appendix behind family visas, asks in-country applicants for “certification by a qualified translator and details of the translator or translation company’s credentials”. Credentials — not a notarial seal.

Notarised. The ITI defines it as a translation that “either a) carries a declaration by the translator that has been signed by the Notary or b) carries a declaration by the Notary Public concerning the original document and the translation”, and notes such translations “are usually for the purpose of making them ‘official’ for overseas use”. The limit is stated plainly on the same page: “The Notary’s signature cannot endorse the quality of the translation, unless s/he is a Qualified ITI Member in the language of the translation.” A notary witnesses who signed; the Chinese remains the translator’s responsibility.

Apostilled. An apostille is further out again. The ITI: “Translations cannot be sealed with an Apostille stamp unless they carry a declaration endorsed by a Notary Public.” The FCDO’s Legalisation Office frames its own service as something you use when “an official in another country has asked you to provide a UK document” — and it will legalise other papers only “as long as they have been certified by a UK ‘public official’, such as a UK notary or solicitor”. Then the sentence that decides most of these cases: “You cannot get documents issued outside the UK legalised using this service – get them legalised in the country they were issued.” A Chinese marriage certificate cannot be apostilled in Britain.

Why a UK certified translation is the answer

Britain appoints no official translators — the ITI puts it as “there is no such thing as a sworn translator” — so the standing that makes a certification credible comes from a professional body rather than the state. Qualified ITI members “can affix ITI Certification Seals to certify a translation”, which the Institute says “renders the translation ‘official’, in the sense it has been done and/or certified by a Qualified ITI Member”. The joint ATC, CIOL and ITI guidance is candid about why formats vary: “As no government-regulated certification system exists in the UK, individual authorities may require certified documents to be presented in a specific format.” That is the reason to read your own recipient’s guidance rather than a generic checklist.

What I send you is built to that standard:

• Every field rendered, in the original layout, so each English line sits where the Chinese line sits and a caseworker can read the two side by side.
• Seals, chops and handwriting described in place rather than dropped as graphics — a partly legible red seal is reported as far as it can be read, and illegible text is bracketed rather than guessed.
• Names romanised to match your passport, with a translator’s note where the Chinese document spells them differently.
• A certification page carrying the gov.uk wording, the date, my signature, my full name, ITI membership number and contact details — checkable on the Institute’s public register without coming back to you.

When notarisation or an apostille genuinely applies. Two situations, and they are real. First, when the receiving body names it — that request tends to come from a Chinese employer, court or authority rather than a UK one, so get it in writing before you pay. Second, when a UK document is going abroad and the foreign official wants it legalised; that is the Legalisation Office route above, and it runs through a UK notary or solicitor. Neither situation is the ordinary one of a Chinese document submitted inside the UK. And a certified translation, however well made, does not make your underlying evidence sufficient — a caseworker can still ask for more.

What to do next

1. Ask the recipient, in writing, which word they use — “certified”, “notarised” or “legalised”. A screenshot of their own guidance settles the argument better than any translator’s opinion.
2. If the answer is “certified”, stop there. Send me clear colour scans or photographs of every page, including the reverse of anything stamped.
3. Send your passport name page too, so the romanisation is fixed against it before submission.
4. Expect £30 per page of 250 words; a single certificate is normally back within 24 hours, longer files in one to two working days, as a signed PDF you upload alongside the scans.
5. If the recipient really does insist on notarisation or an apostille, treat it as a question about the original document and where it was issued — for a Chinese-issued record that work happens in China, not here.

For how this plays out on specific documents, see Chinese hukou translation for a UK spouse visa and Chinese marriage certificate translation for a UK spouse visa. If an apostille turns out to be the thing you actually need, the apostille and legalisation page explains what that route covers.

Frequently asked questions

Will UKVI reject a translation because it is not notarised?

That is not what the rules ask for. Appendix FM-SE wants a full translation that can be independently verified, dated and signed, with the translator’s credentials. Notarisation is not among the listed items, and paying for it does not strengthen the application.

Can I get my Chinese marriage certificate apostilled in the UK?

No — gov.uk states you “cannot get documents issued outside the UK legalised using this service” and directs you to the country of issue. If a UK body ever asks for one, take that back to them before spending anything.

Is a notarised translation more accurate than a certified one?

Not inherently. The ITI notes a notary’s signature “cannot endorse the quality of the translation” unless the notary is themselves a qualified ITI member in that language. Accuracy stays with the translator either way.
