The main difference between an apostille and legalisation is whether the country where you’ll use the document is a signatory to the Hague Apostille Convention.

  • Apostille: A single certificate used for countries that are members of the Hague Convention. It’s a more straightforward process.
  • Legalisation is a multi-step process that is more complex and used primarily for countries that are not members of the Hague Convention.

Here’s a more detailed breakdown:

  • Apostille: This is a single-step process. The designated authority in the issuing country (in the UK, the FCDO) attaches an apostille certificate directly to the document (or to a solicitor/notary’s certification).
  • Legalisation: A multi-step process. Typically, it involves:
    1. Certification by a UK solicitor or notary public (often required).
    2. Authentication by the FCDO (issuing an apostille).
    3. Authentication by the embassy or consulate of the destination country in the UK.
