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
Documento Nacional de Identidad or DNI (which means National Identity Document) is the main identity document for Argentine citizens. It is issued at a person's birth, and must be updated at 8 and 14 years of age, and thereafter every 15 years in one format: a card (DNI tarjeta); it is valid if identification is required, and is required for voting. They are produced at a special plant by the Argentine national registry of people (ReNaPer).
