Civil records here, company records elsewhere
Most official errands in a city end at a public desk, and this one does not. Wolverhampton Register Office at the Civic Centre, St Peter's Square, Wolverhampton WV1 1RU holds the birth, marriage and death entries for the area and prints signed copies of them on request. A company's founding document is a different class of record and lives nowhere in that building, so the door most people would try first is the wrong one.
The version that travels
Since nothing is handed over locally, a sheet goes in the post instead. To apostille an Articles of Incorporation in Wolverhampton, the copy that travels should be one the national company register has issued, not a print run off inside the business. An apostille is a slip that one state fixes to its own public papers so a reader abroad will take them at face value, and it goes on a sheet that already carries an official signature.
What it costs and how long it sits
Two published charges cover the whole road. The standard postal rate is £45 per document, and a registered business can use a next-day service at £40 per document. Each sheet is charged on its own terms, so a bundle of company papers is really several jobs sharing one envelope. The examination itself is short; the calendar is mostly postage at either end of it.
Where the marked sheet lands
A company reaches for this when a body abroad wants a public paper it can read without querying where the paper came from. Opening an account, setting up a branch or signing with a partner overseas are the usual reasons a set of articles leaves the country. The slip comes back fixed to the sheet, and the pair should stay joined for the rest of the journey.
