The validity of documents issued by institutions or authorities of a certain country is affected by territoriality; this means, for a document that has been issued in a diverse country in which it will be used, its transcendence must be subject to a process of legalization and recognition.
To facilitate such procedure on October 5th, 1961 in The Hague, The Netherlands, 109 countries joined to form the Apostille Convention (also known as The Hague Convention). This procedure simplifies the legalization of documents by a single procedure called “apostille”, which consists of certifying and ratifying that the signature and seal of a public document were issued by the competent authority within the exercise of its functions and in use of its powers.
When carrying out this procedure, the validity required in a document may be granted to make use of it in another country, in this case Mexico.
