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.
Identity document
Danish citizens are not required by law to carry an identity card. A traditional identity document (without photo), the "personal identification number certificate" (Danish:"Personnummerbevis") is of little use in Danish society, as it has been largely replaced by the much more versatile "National Health Insurance Card" (Danish:"Sundhedskortet") which contains the same information and more. The National Health Insurance Card is issued to all citizens age 12 and above. It is commonly referred to as an identity card despite the fact it has no photo of the holder. Both certificates retrieve their information from the Civil Registration System. However, the "personnummerbevis" is still issued today and has been since September 1968.
