Figures do not translate themselves
Most of a certified translation for Panama is sentences, and sentences behave well. The parts that misbehave are the ones printed as figures. A date, a time of day, a measurement: each seems to need no translating at all, and that impression is what lets a real ambiguity travel abroad untouched.
The difficulty is that a figure carries a convention along with it. Read with one habit it says one thing; read with another it says something quite different. Neither reader is being careless, and neither has anything on the page to tell them which habit the writer had in mind.
Spanish, with the month written out
A certified translation into Spanish in Sunderland renders the words and disciplines the numbers. The main tool is a plain one: a date is set down with its month spelled as a Spanish word, so day and month cannot trade places in a reader's mind, however the English sheet chose to print them.
The English document is left untouched by any of this. It keeps its own layout and its own figures, and the Spanish pages sit alongside. Anyone holding both can see how a spelled-out month answers to the figures printed opposite, which is much of the reason the pair is kept together.
Signed for the figures as well as the words
The certification behind a certified translation in Sunderland for Panama is the translator's certificate of accuracy, fastened to the Spanish pages and signed by a certified translator. It stands behind the whole of the work, and that takes in every decision about how a date, an amount or a measure was set down.
No sworn standing is required on this route, so the credential that counts is the certified translator's own. Because one person signs for words and figures alike, a bundle of documents receives a single consistent treatment instead of a different rule appearing on each sheet.
Per-page cost and turnaround
Work is priced at about £25 per page, with 2–3 business days as standard and a 24-hour express option. Pages are counted as the sheets that carry text, so a page thick with dates counts as one sheet like any other, since the care goes into judgement rather than into extra volume.
An official Spanish translation in Sunderland is built from whatever copy arrives, which means the figures on that copy have to be readable in the first place. A newly printed certified copy from Sunderland Registration Service leaves no digit to be guessed at, and your own certificate stays out of the post entirely.
