What is an apostille, exactly?
An apostille is an official certificate from the UK government's Foreign, Commonwealth & Development Office (the FCDO) that authenticates the signature, seal or stamp of the public official on your document. It confirms who signed or sealed it, not the contents, so it can be recognised in other Hague Convention countries without further FCDO or embassy legalisation.

- Crown seal & signature of the Foreign, Commonwealth & Development Office
- Unique reference number, verifiable on GOV.UK
- Hague Convention (1961) wording, recognised in 120+ countries

It confirms who signed or sealed the document. It is not proof that the document is genuine, true or accurate, and the certificate says so in its own small print. Whether an apostille is enough for your purpose is decided by the authority receiving the document, so check their requirements or take advice from a lawyer in that country.
