Foreign embassies or consulates, like Brazilian Consulate, often require an apostille or notarial certificate for vital records certificates. The 1961 Hague Convention established the apostille as a form of authentication for its member states.
The apostille certifies the authenticity of the issuing official’s signature. Countries that are nonmembers of the 1961 Hague Convention are issued notarial certificates, which also authenticates the issuing official’s signature. The process to authenticate a document by the DFA turnaround is 10-12 working days.
