How to tell an authentic certified translation from an edited one.
A certified translation is only useful if the receiving office can satisfy itself that nobody has changed it since it was signed. That is what people mean by linguistic authenticity: not that the prose is elegant, but that the meaning of the original has survived intact, and that there is a named person accountable if it has not.
What the certification actually proves
Our certificate of accuracy does four things, and each one exists so a caseworker can check something:
- it names the document that was translated
- it states that the translation is accurate and complete
- it carries the translator’s name, signature and the date
- it gives contact details for the translator and the company
Anyone holding the file can therefore contact us and ask whether we issued it. That is the whole verification chain, and it works without any technology more exotic than a signature and a phone number.
What tampering looks like
Most altered translations are not sophisticated. In practice the pattern is a PDF edited after certification, or a document retyped from scratch:
- a name changed to match a passport, while the original spelling appears elsewhere in the file
- a date of birth adjusted by a year or a day
- a certificate page reused from another translation, with the document swapped
- a stamp or seal described in the text but missing from the translated layout
- formatting that no longer mirrors the original, so nothing can be matched line by line
The tell is almost always internal inconsistency, not a broken seal. This is why our translations reproduce the original layout and note seals in square brackets: it gives the caseworker something to match against.
Where digital signatures fit in
Document security is moving towards cryptographic methods. In the EU, eIDAS 2.0 introduces qualified electronic attestations and qualified electronic signatures, and PDF standards such as PAdES allow a signing certificate to be validated years after the fact. A SHA-256 hash of a document will change if a single character changes, which is a genuine check on later edits.
It is worth being precise about what this means for a translation ordered in the UK today. Those standards protect a file that has been electronically signed by a qualified provider. A certified translation is a different instrument: a signed statement from a named translator and company, delivered as a PDF, which the receiving organisation verifies by contacting the signatory. We do not issue qualified electronic signatures, and a document that needs them is a different piece of work. If an office has asked for a digitally signed file, say so at the point of order and we will confirm what can be provided.
What a buyer can check
- Does the certificate name the document? A generic certificate attached to the wrong file is the most common problem, and the easiest to catch before anything is sent.
- Is there a date? Undated certifications get queried.
- Are contact details present? A signature alone is not verifiable.
- Does the layout match the original? Page count, tables, stamps and signatures should line up.
- Is the spelling consistent with the passport? Transliterations must agree across every document in an application.
If an office questions a translation
Ask them which element is missing. In most cases it is one of the five items above, and the fix is a corrected certificate rather than a new translation. If the query is about the translator’s credentials, that is usually answered with the membership details we hold for the linguist who did the work.
