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
A birth certificate is signed by the head of the registrar or other public authority issuing the certificate (e.g., the consulate). Signature of the registrar should have a transcript (initials and surname) and sealed with the official seal.
