Two countries, two habits, one row of figures
A date written purely in figures carries no clue about the order somebody wrote it in. Britain puts the day at the front; American paperwork puts the month there. The same groups of digits therefore name two different days depending on who is holding the sheet, and nothing printed on it announces which reading was meant.
How the English pages settle it
The fix is small and quite ordinary: the month is written as a word. Once that happens the order stops mattering, because a month spelled in letters cannot be taken for a day. A translator does this wherever a date turns up, including in margins, inside stamps, and on the thin line at the foot of a sheet where dates so often hide.
Why it is worth the fuss
A shifted date is not a typing slip. It can put a marriage before a birth, drop an event outside a window somebody is measuring, or make two of your own papers contradict each other. A reader in the States has no way to tell a real date from a misread one, so the doubt has to be removed while the pages are being written rather than argued over afterwards.
Who signs, and on what standing
The pages are signed by a certified translator, who attaches a dated certificate of accuracy saying the English matches the source. A certified translation into English in Stoke-on-Trent stands entirely on that signature. There is no court appointment behind it and no oath register the signer could appear on, which keeps the question of who wrote this refreshingly simple.
Cost, days and a clean copy
An official English translation in Stoke-on-Trent is priced at £25 for each side of paper, with 2–3 business days as standard and 24 hours on the express route. Stoke-on-Trent Register Office supplies fresh certified copies of civil records by post. A crisp copy is worth having, because a faded date is the hardest mark on any sheet to read correctly.
