Registered here, or just living here?
People assume the city they live in is the city that holds their papers, and often it is not. A civil record sits with the office that registered the event when it happened, and it stays there. Someone who moved to Manchester at twenty has a birth entry hundreds of miles away, and that entry is the only place a sealed copy can come from.
Manchester Register Office at Heron House, 47 Lloyd Street, Manchester M2 5LE keeps the entries made in the city and issues certified copies of them by post. It is the local part of this whole route, and for many readers it is the only part that is local at all.
What Kuwait asks for
An apostille for Kuwait is not the certificate that ends the file. Kuwait has not joined the Hague Apostille Convention, so document legalisation for Kuwait runs on through a consular desk after the British stage. That is fixed by the destination and cannot be changed by anything you do at the start.
So there is no apostille issued in Manchester for use in Kuwait to be collected anywhere, and an apostille from United Kingdom to Kuwait leaves the sheet a stamp short of what the far end looks for. Anyone reading up on what you need for an apostille for Kuwait should treat the consular stage as part of the plan from the beginning.
Once the copy is in your hands
From here nothing is local to anywhere. The certificate is added by the Legalisation Office (Foreign, Commonwealth & Development Office), which handles the whole country from a post box in Milton Keynes and charges its official fee for each sheet it stamps. No queue, no appointment and no address of yours affects it.
That is why the early question is the one worth care. Get the source of the record right and the remaining steps are the same for a reader in Manchester, in Kuwait or anywhere else. Get it wrong and you have paid for a sheet that cannot go forward.
Papers that no register office holds
Degrees, company papers and police records never sit in a register office, so the same question has a different answer for them: the body that issued the sheet is the one to go back to. Work that out per paper rather than per person, since a family often needs items from three or four separate sources.
