City of Sydney Relationships Declaration
Other institutions such as the Registry of Births Deaths and Marriages no longer accepts an Australian Marriage Certificate as a form of ID – this creates an equal situation for both opposite sex and same sex couples as both are not allowed to present their relationship certificates as a form of ID.
Brazilian identity card
The documents required to obtaining an identity card depend on whether the applicant is single, married or naturalized. Single people need a birth certificate (the original or a certified copy), while married people can use their marriage certificate, and naturalized people can use a naturalization certificate. An applicant's CPF number can be printed on the card alongside the RG number, if desired.
