What does an apostille mean?

Apostille is a French term that means marginal annotation. It refers to a means by which foreign public documents are legalised, making them suitable and trustworthy enough for use in a new country that is part of the Convention.

Can I have any documents apostilled?

Yes. You can have any documents apostilled, from marriage certificates to academic certificates. Contact our apostille office for more information.

Do I need a notary public for my apostille?

Not really; a notary public can be used to verify any photocopies of documents you may have. The certificate is glued to the back of the document or the front page of a double-sided document with all its details; the stamp or seal and signature. The capacity in which the person signed the document is also authenticated. You can contact the FCDO office in Central London for this and other services.

What Is An Apostille? [Updated Explanation for 2026]

A UK apostille certificate is a physical piece of paper, 16 cm high and 15 cm wide (6.3 inches by 5.91 inches), issued only by the UK government’s legalisation office, the FCDO (Foreign, Commonwealth & Development Office).

It’s partially glued to the back of an original UK public document or a certified copy, bearing a stamp, signature, and embossment to confirm the authenticity of the document’s signatures, seal, and stamps.

The apostille certificate contains vital information↓, including the name and capacity of the person who signed the document, details of any seal, and a unique reference number that can be verified on the UK government’s website.

Remember, while an apostille validates the origin and legitimacy of your document, it doesn’t confirm the accuracy of its content or automatically make it legally binding abroad.

But why would you need this?

An apostille is essential if you plan to use your UK documents in another country that’s part of the Apostille Convention (currently 126 countries).

It serves as an international seal of approval, verifying that your document is genuine and issued by a recognised authority in the UK.

This verification is often required for various purposes, such as:

Studying or working abroad: Educational qualifications, professional certifications, and employment contracts might need to be apostilled for recognition in a foreign country.
Getting married or registering a birth overseas: Birth certificates, marriage certificates, or divorce decrees may need an apostille for legal validity in another country.
Conducting international business: Company documents, powers of attorney, or commercial contracts might require an apostille for cross-border transactions.
Legal proceedings in foreign courts: Court orders, affidavits, or other legal documents may need an apostille to be admissible in a foreign jurisdiction.

What an apostille is not:

No substitute for legalisation: If the country you need your document for is NOT a member of the Apostille Convention, you’ll need a more complex process called “legalisation.” (also called ‘attestation’).
Not a universal guarantee: Even with an apostille, your document might not be automatically accepted. Some countries may require translations or additional certifications.
Not a content verification: An apostille confirms that your document is officially issued and that the signatures are real, but it doesn’t guarantee that the information inside is accurate or valid.
No legal enforcement: An apostille helps verify a document’s authenticity but doesn’t automatically make it legally binding or enforceable in every country.
