You can get certain official UK documents ‘legalised’ by asking the Legalisation Office to confirm that the signature, stamp or seal is from a UK public official.

You might need to do this if an official in another country has asked you to provide a UK document and they’ve said it must be legalised.

The Legalisation Office will check the signature, stamp or seal. If it’s genuine, they’ll legalise the document by attaching a stamped official certificate (an ‘apostille’) to it.

You can’t get documents issued outside the UK legalised using this service - get them legalised in the country they were issued.

What you’ll need

To use the service you’ll need:

  • the documents you want to legalise
  • a credit or debit card for payment
  • the address you want your documents returned to
  • access to a printer

If you don’t enter any information for more than 30 minutes, your application will time out and you’ll have to start again.
