South Australia has led the world in land title security since the original implementation of the Torrens system.

The key principles of the Torrens system, which together establish indefeasibility of title, are:

  • Mirror principle - the Land Titles Register accurately and completely reflects the current ownership and interests about a person's land.
  • Curtain principle - because the Register contains all the information about the person's land, ownership and other interests do not have to be proved by examining all the lengthy complicated documents forming the chain of title.
  • Indemnity principle - backed by the government, the Assurance Fund provides compensation to a person who suffers loss of land or a registered interest as a result of fraud or error in registration.
