The Real Property Act 1858, 21 Vict. c. 15, is the short title of an act of the Parliament of South Australia, with the long title "An Act to simplify the Laws relating to the transfer and encumbrance of freehold and other interests in Land". After being introduced as a private member's bill by Sir Robert Richard Torrens, it was passed by both houses and assented to by the Governor of South Australia, on 27 January 1858. It was the first law in the world to institute what has become known as the Torrens Title system of property law, and is sometimes referred to as the "Torrens Title" Act 1858.
