Apostille vs Consular Legalisation: What’s the Difference? (2026 Complete Guide)

Are you confused about how to get your documents legalised? You are not alone. This process can sometimes be confusing and time-consuming. Read our expert guide to learn the key differences between Apostille Legalisation and Consular Legalisation.

Summary of Document Legalisation:

• Apostille Legalisation is a one-step attestation process by the FCDO for direct use in Hague Convention countries.
• Consular legalisation is required for non-Hague Convention countries in addition to the Apostille legalisation.
• Understanding which process you need can save time and money.
• Some documents may require certification by UK solicitor or notary public before submitting for Apostille and consular legalisation.

What is Document Legalisation?

Document legalisation is the process of certifying/authenticating documents for use in foreign countries. Whether relocating abroad for work or studies, getting married overseas, conducting international business transactions (e.g opening subsidiaries), or purchasing a property, you’ll likely need to legalise your documents.

Understanding Apostille Legalisation or Attestation

An Apostille (also known as Hague Apostille) is a standardised attestation/legalisation process established by the Hague Convention of 1961. This international Treaty was specifically designed to simplify the process of document legalisation between member countries abolishing the requirement of further legalisation by the diplomatic body of the destination country in the country of origin of the document.

In the UK, the Apostille is only issued by the Foreign, Commonwealth and Development Office (FCDO) Legalisation Office in Milton Keynes. In most other countries, the Apostille is issued by either the Ministry of Foreign Affairs, notary offices or local court offices/tribunals.

Key Features of Apostille Legalisation:

• Single-step attestation process
• Standardised format recognised by all Hague Convention member countries
• Typically processed within 1-5 working days
• Apostille in the UK is issued in English/French/Spanish, saving costs with translations into those languages
• Original documents issued by the UK public officials can be Apostilled directly by the FCDO
• Faster processing and cost-effective compared to consular legalisation

What is Consular Legalisation?

Consular legalisation is the traditional method of document attestation required when dealing with countries that are not Signatories to the Hague Convention 1961. This process is more complex, time-consuming and typically involves multiple steps and attendance to the consular section of the destination country in London.

Steps in Consular Legalisation:

1. Check the requirements for each country
2. Document may be first required to be certified by a UK solicitor or a notary public
3. Followed by Apostille legalisation by the Foreign, Commonwealth & Development Office (FCDO)
4. Final legalisation by the Embassy, Consulate or High Commission of the destination country
