Register a significant relationship

What is a significant relationship

A significant relationship is a legally recognised relationship between two adults.

Your significant relationship does not have to be registered to be recognised, but you may find it useful to have a certificate to prove that your relationship exists in emergency situations or when dealing with government agencies.

You can register a significant relationship in Tasmania if you are a couple who:

  • both live in Tasmania
  • are not married or related by family
  • are in a relationship with each other.

You do not need to register a relationship in  Tasmania if you have already formalised a relationship in another Australian state or territory or overseas.
