Apostille or legalisation: what's the difference?

Ask first: which country is the document going to? If the destination is a member of the Hague Apostille Convention, an apostille is enough. If it isn't (such as the UAE, Kuwait or Qatar), you need full consular legalisation.

So the same document is handled differently depending on where it's going. The destination country decides the procedure, not the document type.

An apostille is a single certificate that confirms a document's authenticity in all Hague Convention countries. In Finland it is issued by the Digital and Population Data Services Agency (DVV). It's fast and affordable. One stamp is enough.

An apostille is only valid in Hague member countries. If the destination isn't a member, an apostille alone is not enough.

Consular legalisation is a multi-step chain for countries that are not part of the Hague Convention. The document is first verified in Finland (DVV or a notary), then at the Ministry for Foreign Affairs, then at the destination country's embassy in Helsinki, and finally at the destination country's Ministry of Foreign Affairs.

Every step is mandatory. If even one is missing, the document is rejected on arrival. This is the most common mistake we see.

Saudi Arabia joined the Hague Apostille Convention on 7 December 2022. Since then an apostille is enough for Saudi Arabia, even though full legalisation used to be required. The UAE, Kuwait and Qatar, on the other hand, still require full consular legalisation.

This is exactly why country-specific accuracy matters: one country's rule can change, and following an outdated instruction costs time and money.
