Relationship register

Couples who are not married can apply to register a relationship in NSW. The relationships register provides legal recognition for a couple.

Why register your relationship

  • Registered relationships are recognised as 'de facto' in NSW. Couples in registered relationships are subject to certain obligations and/or restrictions under NSW law.
  • Registered relationship certificates are used to access entitlements, services and records under legislation.
  • In situations outside of legislation, service providers may choose to accept registration of a relationship as proof of legitimacy of that relationship.

Adults who are in a relationship as a couple can apply for registration of their relationship provided at least one of them lives in NSW.

A couple does not have to live together to be eligible to register their relationship.

To apply to register your relationship in NSW both partners must be:

  • over 18 years of age
  • not married to each other or anyone else
  • not already in a registered relationship under this Act or in another state or territory in Australia
  • not in a relationship with another person
  • not related by family

Apply online. See the video for tips about online completion.

Registrations revoked by law and void registrations

Registration of a relationship may also be revoked by law on the death or marriage of a person in the relationship.

A registration is considered void if:

  • the agreement of one or both persons in the relationship was obtained by fraud, duress or other improper means
  • the relationship was registered when either person was mentally incapable of understanding the nature and effect of registration
  • the relationship was prohibited (i.e. one of the persons was married).

Commemorative relationship certificates

Celebrate the registration of your relationship with a commemorative certificate.

You can choose from one of two designs on your relationship registration application form.
