The refusal that happens before anyone reads
Files are turned away without a word of the translation being read. The clerk weighs the object first: are the sheets fastened, is there a signature belonging to a named person, does a stamp cross the join. Only once that survives does anyone start on the text. It feels crude, and it is the only test a stranger with no other information can apply.
Who witnessed the signature in Scotland
The affidavit is a private act, so a notary or solicitor must watch the signature go on before any authority will act on it. In Scotland that witness is a notary public, and in practice the office is held by a practising solicitor. The seal that follows tells a stranger overseas that the signer was identified by a named officer, rather than merely by themselves.
One bundle, not three loose papers
The source sheet, the rendering and the accuracy statement belong together, fastened so that nothing can be lifted out or slipped in. A certified translation of a Translator's Affidavit in United Kingdom is bound that way as a matter of course, with the fastening stamped. Take the staple out and the sworn words no longer point at anything in particular.
What the declaration has to name
Four things carry the weight: the translator, the language pair, the paper being described and the date of signing. Drop any one of them and the declaration stops working as evidence. A certified translation of a Translator's Affidavit in Edinburgh repeats each of those in the target language, so the reader abroad sees the same four plain lines that a reader here would see.
Price, speed and Scottish extracts
The translation cost for a Translator's Affidavit in Edinburgh runs at about £25 a page, with standard delivery in 2–3 business days and a 24 hours express option. Scottish civil records travel as extracts rather than plain photocopies, and Edinburgh Registration Service at City Chambers, 253 High Street, Edinburgh EH1 1YP issues a fresh certified extract, so the copy you already hold need never leave the house.
