Professional translation service
When a receiving authority asks for a notarised translation, the document needs more than an accurate rendering of the original text. It may need a professional translation, a signed certification and an additional notarial step. Translator London helps you prepare translations for that process, with the requirements checked before work starts.

A notarised translation is a translation accompanied by a notarial act. In the UK, the notary commonly witnesses or authenticates the signature or declaration of the translator or authorised representative. The notary does not normally verify the linguistic accuracy of every word. That responsibility remains with the translator or translation company making the accuracy declaration.
This distinction matters when an overseas court, embassy, company registry or educational institution asks for notarisation. A professional certified translation alone may satisfy some organisations, while others expressly require a notary’s signature or seal. Always follow the receiving authority’s written instructions rather than assuming every official document needs notarisation.
The requirement depends on the country and purpose, rather than simply the type of document. Common examples include powers of attorney used abroad, incorporation papers, company resolutions, contracts, affidavits, academic awards, identity documents and civil-status certificates. Some recipients request notarisation of a translator’s declaration; others ask for a notarised copy of the underlying document as a separate step.
Certified translation means a professional translator or company confirms in writing that the translation is accurate and complete. Notarised translation adds a notarial act, typically concerning a signature or declaration. Sworn translation refers to a translator appointed or authorised under particular foreign legal systems; the UK does not operate a universal domestic sworn-translator status. Legalisation or an apostille is a separate official authentication process for eligible documents, administered in the UK by the Foreign, Commonwealth & Development Office.
These terms are not interchangeable. Our comparison of certified, notarised and sworn translation explains the distinctions in more detail. For example, a university may ask only for a certified translation, while an overseas property transaction may require a notarised declaration followed by an apostille. See the UK government’s guidance on document legalisation and check the instructions issued by the destination organisation.
Ordering the wrong certification: a notarial seal cannot substitute for a translation if the recipient needs the content in another language. Equally, an ordinary certified translation might not satisfy an express notarisation requirement. Using incomplete images: cropped stamps, missing reverse-side notes and blurred names lead to delays. Confusing notarisation with an apostille: a notary and the FCDO Legalisation Office perform different checks. Assuming international acceptance: different destinations impose different procedures, and only the receiving organisation can confirm its requirements.
If your document also needs a different type of translation, see our certified translation services or our full service overview.
Not routinely. UK immigration guidance commonly asks for a full, independently verifiable translation with specified certification details. Check the particular visa route. An additional notarial step should only be purchased if required.
Potentially, yes. The notary will need to establish what signature or declaration is being authenticated and which documents must be presented. It is best to confirm the notarial requirements before the translation is finalised.
No. An apostille is a separate legalisation procedure. Whether it is needed depends on the receiving country and organisation. We will not describe an ordinary notarised translation as apostilled unless that step has actually been completed.
Some recipients accept digital PDFs; others insist on an original signed pack, certified hard copy or wet-ink notarial document. Ask the recipient and let us know before choosing delivery.
Costs depend on the language pair, document length, notarial requirements, number of copies and any legalisation or courier arrangements. Upload the document for an itemised assessment rather than relying on a single generic price.
Tell Translator London where the translation will be used, upload the complete document and include any instructions from the receiving organisation. We’ll help establish the appropriate translation and certification route.
