Bolivia asks for Spanish
Bolivian offices read Spanish, and a record written in English is not something a clerk there can act on. A certified translation into Spanish in Birmingham gives them a version they can work from, signed by the person who wrote it. Your English paper is unchanged and stays with you throughout.
The two sheets are meant to travel as a pair. The Spanish is not a replacement, and it never carries the seals of the issuing body on its own. Handed in together, they let a Bolivian reader match a stamp on the English to the line describing it in Spanish.
How the price is built
Everything hangs on the page count. At about £25 a page the total is simply sides multiplied by rate, which means you can arrive at the figure before anyone quotes you. That transparency matters most on long files, where guesswork otherwise turns a translation into an open-ended bill.
Nothing else is metered. The certificate of accuracy, the layout work and the seal descriptions are all inside the page price. An official Spanish translation in Birmingham with ten sides costs ten pages, no matter how much ink is on them or how many stamps had to be written up.
Who signs it and how long it takes
The signature belongs to a qualified certified translator, and the certificate beneath the Spanish gives their name and the date. That is the certified form Bolivia accepts. Because a named person stands behind it, a clerk who queries a line has somebody to put the question to rather than an anonymous file.
Plan on 2–3 business days for a certified translation for Bolivia, or 24 hours in express. If a civil record in the bundle needs replacing first, Birmingham Register Office on Holliday Street issues fresh certified copies of births, marriages and deaths, so the original never has to go anywhere.
