How do I know if I need an apostille or legalisation?

Check if the destination country is a member of the Hague Apostille Convention. If yes, you need an apostille. If no, you need consular legalisation. You can check membership on the Hague Conference website or ask your Notary Public.

Can I get both an apostille and legalisation for the same document?

No. You use one process or the other, depending on the destination country. A document going to a Hague member country gets an apostille. A document going to a non-member country gets legalised.

Apostille vs Legalisation — Which Do You Need?

Q: What is the difference between an apostille and legalisation?

An apostille is a single certificate used for Hague Convention member countries (120+). Legalisation is a multi-step process required for non-member countries, involving DFA authentication plus embassy verification. Apostille is faster and cheaper.

When you need to use an Irish document in another country, you'll encounter two terms: apostille and legalisation. Understanding which one you need — and why — is essential to getting your documents accepted abroad. This guide provides a clear, practical comparison.

The Fundamental Difference

Apostille is for documents going to countries that are members of the Hague Apostille Convention (over 120 countries). It's a single certificate issued by the Department of Foreign Affairs.

Legalisation (also called consular legalisation) is for documents going to countries that are NOT members of the Hague Convention. It's a multi-step process involving the DFA and the embassy of the destination country.

Process Comparison

Apostille Process (2 steps)

Notarisation by a Notary Public (for private documents)
Apostille from the Department of Foreign Affairs

Legalisation Process (3 steps)

Notarisation by a Notary Public
Authentication by the Department of Foreign Affairs
Legalisation by the embassy/consulate of the destination country

Time Comparison

Apostille: Same-day (DFA walk-in Dublin) or 5–10 working days (postal)
Legalisation: 2–6 weeks typically, depending on the embassy

Cost Comparison

Apostille: Notarisation (€65–€150) + DFA fee (€20–€40) = approximately €85–€190
Legalisation: Notarisation + DFA fee + embassy fee (varies widely, €20–€100+) = approximately €105–€350+

Which Countries Use Which?

Apostille countries include: All EU states, UK, USA, Canada, Australia, Japan, South Korea, India, Brazil, and most others worldwide.

Legalisation countries include: Some nations in the Middle East, Africa, and parts of Asia that have not joined the Hague Convention.

Always verify the current status on the Hague Conference website, as the membership list grows over time.

The Role of the Notary Public

Both processes start with the same first step: notarisation by a Notary Public. The notary can also advise you on which process applies to your destination country and what specific requirements that country may have.
