One job above all others
Most records state a fact about a person. This one states a relationship between two written forms of the same person. A certified translation of a Legal Name Change Certificate in United Kingdom therefore has an unusually narrow target: reproduce both names, in both spellings, so a reader can put this sheet beside another and see that they refer to one individual.
Letters, not sounds
Names are copied, not converted. A form with an accent keeps the accent; a hyphen stays a hyphen; a name that looks unusual on the page stays unusual. The temptation to smooth a spelling into something more familiar is real, and it is resisted on purpose, since the whole value of the sheet lies in the exactness of the match.
The same restraint applies to the surrounding text. Dates, reference numbers and the wording of the declaration are carried across as they stand. An official translation of a Legal Name Change Certificate in London is meant to be read next to the source, and anything reworded for elegance would make that side-by-side reading harder rather than easier.
How it sits with the rest of your papers
This sheet rarely travels alone. It goes with the papers that still carry the earlier name and with those issued since the change, and it is the hinge between the two groups. When the whole set is translated at the same time, the names are rendered identically across every sheet, which is far easier for a reader than a bundle assembled from separate jobs done months apart.
Who signs it
An ITI/CIOL-qualified certified translator produces the text and signs a statement of accuracy describing the sheet, the date and themselves. The claim is limited to the words: these two documents say the same thing. Whether the change was properly made is a separate question, settled by the deed itself and not by anyone working on the translation.
Rate, days and keeping the deed safe
Work runs from an image, so the signed deed stays in your own file throughout. Westminster Register Office at 317 Harrow Road, London W9 3RJ issues certified copies of birth, marriage and death entries, which is useful when those older records are going into the same bundle. The office works by post and by appointment, and it does not translate anything itself.
