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.
Birth certificate
Both versions of a certificate can be used in the verification of identity by acting as a support to other information or documentation
provided. Where proof of parentage is required only a full certificate will be accepted.
