The apostille: everything you need to know
Last updated: April 2026
What is an apostille?
An apostille is an official document that certifies the authenticity of a public act so that it is recognised in another country.
The apostille was established by the Hague Convention of 5 October 1961. 125 countries have signed this Convention.
When do you need one?
You will need an apostille if your document was issued in a foreign country that has signed the Hague Convention and it needs to be used in Belgium, or vice versa. Examples:
- Foreign birth certificate for a marriage or other procedure in Belgium
- Criminal record for a visa or nationality application
- Diploma for academic or professional recognition
If your document was issued by an EU member state, an apostille is generally not required for use in Belgium (EU Regulation 2016/1191).
If your document was issued by a country that has NOT signed the Convention, see the article "Legalisation: when an apostille is not enough".
How do you obtain an apostille?
The apostille must be issued in the country where the document was issued by the competent authority:
- Belgium: FPS Foreign Affairs
- India: Ministry of External Affairs (MEA)
- United States: Secretary of State of the relevant state
- Turkey: Ministry of Justice or competent Court of Appeal
