Legalization (international law)


In international law, legalization is the process of authenticating or certifying a legal document so a foreign country's legal system will recognize it as with full legal effect.

Rationale and procedure

Authentication by legalization is widely used in international commerce and civil law matters in those jurisdictions where the simpler apostille system has not been adopted. The procedure of legalization can be simply split into 3 stages, though each stage can vary in the amount of steps required:
Broadly speaking, the aim of any international document authentication process is to solve a fundamentally practical problem: how can civil and judicial officials reliably verify the authenticity of a document that was issued abroad?
Legalization attempts to solve this dilemma by creating a chain of authentications, each by a progressively higher government authority so as to ultimately narrow the point of contact between countries to a single designated official. Therefore, by authenticating the signature and seal of this final official a foreign jurisdiction can authenticate the entire chain of verifications back to the entity responsible for issuing the original document without scrutinizing each "link" individually.
For example, a Canadian individual who wishes to immigrate to Indonesia, both jurisdictions which are not party to the Hague Convention, must first authenticate their vital statistics documents with the appropriate provincial authority or Global Affairs Canada, then take those authenticated documents to be legalised at the Indonesian overseas mission with jurisdiction over their place of residence.
This is not always the case vice versa, though. An Indonesian individual who wishes to immigrate to Canada does not need to do any such thing, as Canada does not make authentication of foreign public documents a requirement for their acceptance in the country.

Apostille Convention

The Hague Convention Abolishing the Requirement for Legalisation for Foreign Public Documents has supplanted legalization as the default procedure by a system of apostille. It is available if both the origin country of the document and the destination country are party to the treaty. The apostille is a stamp on which standard validating information is supplied. It is available from the competent authority of the origin country, and often the document has to be notarized before it can be apostilled. In the United States the Secretaries of State for the various states are the competent authorities who can apply an apostille. A list of the competent authorities designated by each country that has joined the treaty is maintained by the Hague Conference on Private International Law.
