The Collaborative International Dictionary of English v.0.48:
Torrens system \Tor"rens sys`tem\
A system of registration of titles to land (as distinct from
registration of deeds) introduced into South Australia by the
Real Property (or Torrens) Act (act 15 of 1857-58), drafted
by Sir Robert Torrens (1814-84). Its essential feature is the
guaranty by the government of properly registered titles. The
system has been generally adopted in Australia and British
Columbia, and in its original or a modified form in some
other countries, including some States of the United States.
Hence
Torrens title, etc.
