Welcome to the Legalisation Office website. The Legalisation Office of the Foreign and Commonwealth Office (FCO) is the only competent authority to issue apostilles in the UK.
Legalisation is the official confirmation that a signature, seal or stamp on a UK public document is genuine. It does not authenticate the content of the document. Legalisation is usually required by foreign authorities before they will allow a UK document to be used for official purposes in their country.
The UK does not require any documents to be legalised for use within the UK.
To help us legalise your document(s) quickly it is important that you read the How to Apply page before you send your document(s) to the Legalisation Office. If your application is incomplete in any way, we will be unable to legalise your document and it will be returned to you with further instructions as to what to do next. Some applications are non-straightforward and may take longer to process.
Milton Keynes Postal Service - For all applications from members of the public and business customers
Pre-registered Businesses only - For the Centre Point Premium Service and Drop-Off and Collection facility
