It takes around 48 hours for a document to be legalised if you apply through GOV.UK. You must download and complete an application form and post it to the Legalisation Office in Milton Keynes, along with the document(s) you wish to have legalised. The document(s) will be authenticated, an apostille certificate will be attached to each one, and they will be returned to you by courier.
We can also provide an online document legalisation service for existing clients who incorporated through our website. You can find out more here.
