It is a certification used for the authentication and legalisation of documents issued by government departments and agencies. The stamp verifies the authenticity of your documents. In most foreign countries, you need to get apostille legalisation of your documents before you can use them for official purposes. Before the Apostille Hague Convention, everyone had to follow the authentication and legalization process. This cumbersome document legalization process was made more efficient during the 1960s when the Hague Apostille Convention was signed by participating countries. This streamlined the process required to authenticate a document considerably and issues a Hague stamp. Documents with this seal are then fully authenticated and legalized.
