The language Madagascar works in
Madagascar handles paperwork of this kind in French, so French is what your document is turned into. A certified translation into French in Sheffield is written from a scan, and your English sheet is never altered or replaced. The French pages sit beside it, signed and dated by a translator who took an oath before a court and is answerable for every line.
A page is not only text
Look at an official English certificate and count how much of it is not sentences. There is a stamp near the foot, a seal pressed into the paper, a reference number in a box, a date written by hand and a signature that nobody has ever read. All of it counts as part of the record, and a reader abroad expects to find all of it.
None of that survives a plain word-for-word job. So each mark is written up: its place on the sheet, its shape, the words around it, and whether it was inked or pressed. The French set then tells the reader the same story the paper tells, in the order the eye meets it, rather than a tidy summary of the sentences alone.
Described, never redrawn
It is tempting to paste a picture of the seal into the French version and be done. That would be worse than useless. An image proves nothing on its own, and a reader who sees one may take the French pages for a substitute for your certificate. They are not a substitute; they are a companion sheet, and everything on them is a report of what the English paper shows.
The same rule covers reference numbers, box codes and anything written in a hand. Numbers are copied exactly, never rebuilt to look French, because a clerk compares them character by character against a record somewhere. Words get explained in the local language; identifiers get reproduced. Keeping those two jobs apart is most of the craft in this kind of work.
Cost and timing
The rate is £25 a page and the count is agreed from the scan before writing starts. Standard work takes 2–4 business days; the express route brings that down to 24–48 hours, and both produce the same signed set. Send every side of every sheet in one go, including any reverse that carries a stamp, and the count is right the first time.
