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 Interrogation
Identity interrogation is a method of authentication or identity proofing that involves posing one or more knowledge-based authentication questions to an individual. Identity interrogation questions such as "What is your mother’s maiden name?" or "What are the last four digits of your social security number?" This questioning process requires individuals to reveal personally identifiable information (PII) in order to prove his or her identity. It is a method businesses use to prevent identity theft or impersonation of customers.
