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.
Canadian nationality law
A special birth certificate issued by the Department of National Defence to children of CAF members born abroad before 1979, known as DND 419, is not a proof of citizenship due to the lack of legal status of the certificate. This has caused difficulties for some individuals as they were forced to apply for a certificate of citizenship to confirm their status and to apply for a passport.
