Births, deaths and marriages

Register a relationship

Registering your relationship with Consumer and Business Services (CBS) means that your relationship is legally recognised. It can make it easier to access entitlements and assert your rights, including in medical situations. Registering your relationship is not the same as getting married.

Who can register

You can register your relationship if you are 18 years of age or older and in a relationship with another person as a couple. At least one of you must live in South Australia. Couples may apply irrespective of their sex or gender identity.

Your relationship can't be registered if you or your partner are:

  • married
  • already in a registered relationship or corresponding law registered relationship
  • in a relationship as a couple with another person
  • related by family.

What you'll need

CBS will ask both people in the relationship:

  • for personal details
  • if you plan to have a ceremony
  • to prove your identity
  • to complete a statutory declaration, which must be witnessed by an authorised person
  • to provide evidence that a previous relationship has ended, if you have previously been married, in a registered relationship, or corresponding law registered relationship.

What happens next

Your relationship can be registered 28 days after lodging the application and paying the appropriate fees. You can't fast track this registration.

Contact the Department of Home Affairs to find out if registering your relationship can support your visa application.

Check with the relevant authorities - eg Australian Passport Office - to find out what evidence is needed if you decide to take on your partner's surname.

Registry office ceremony

Couples are not required to have a ceremony when they register their relationship. However, relationship ceremonies can be conducted at Chesser House, performed by registry staff.

Nominate a preferred date for the ceremony in your application. If your first choice isn't available, we will give you alternative dates to choose from.
