Apostille vs. Embassy legalisation for Kuwait
Two arrangements exist for proving a British signature abroad. Under the first, a treaty lets one certificate speak for a document in every member country. Under the second, the receiving state reads the file through consular officials of its own before it counts for anything. Kuwait uses the second, so an apostille for Kuwait completes nothing, whether you prepare one sheet or five.
Kuwait's Hague status & what it means
Kuwait has not joined the Hague Apostille Convention. An apostille from the United Kingdom to Kuwait has no standing there, and no number of them adds up to one that does. The treaty road is closed at that end, which is why every copy in your plan takes the longer consular way and carries the longer wait along with it.
Decide the count before the first sheet moves
The question people skip is how many finished documents the plan actually needs. A single job with one recipient needs one. A move that involves an employer, a school place and a government file may need three, because each of those may keep what it is given rather than pass it on. Nothing about this road makes a second copy quick to bolt on later.
Copies are cheapest at the very beginning. Plymouth Register Office at Derriford Park prints certified copies of a birth, marriage or death record from the register, so ordering two instead of one is a small step taken once. Everything after that point is priced and timed per sheet, and repeats in full for each extra you decide on afterwards.
Cost & timing for this route
The British side is the predictable half: £45 for each document by post at the Legalisation Office, or £40 for each document on the next-day route open to registered businesses. The consular charge is set by the receiving side and no figure for it appears on this page. Both halves repeat for every copy, so the count you choose multiplies the whole job rather than a part of it.
Destination-specific requirements
Kuwait asks for consular legalisation, and the Kuwaiti consular service in Britain reads the document itself before it acts. That makes the version you send worth some care: a certified copy drawn from the register rather than anything run off at home. Prepare each copy to the same standard, because each one will be looked at on its own by whoever ends up receiving it.
