You get a UK public document ‘legalised’ by asking the UK government to confirm that a UK public official’s signature, seal or stamp on the document is genuine.

You might need to do this if a local authority abroad has asked you to provide a document and they’ve said it must be legalised.

How to get a document legalised

  1. Check your document can be legalised.

  2. Pay online for the service.

  3. Complete the legalisation application form.

  4. Send your documents, application form, a blank A4-sized envelope and the payment confirmation page (which you’ll get after you pay online) to the relevant address. There are different addresses depending on how you send the documents and where you’re sending them from.

Once received, your documents are usually legalised and sent to you within 48 hours. You’ll get an email if there’s a delay.

Businesses can register for the legalisation premium service.
