'The 'mirror' principle, the 'curtain' principle and the 'insurance' principle form the tripod on which the whole system of land registration rests.....( for that matter all processes of tptb registration appear based on torrens)
1. The mirror principle - the registry must reflect 'the truth' of the matter - i/e respect the registry. (the register is the truth!!)
2. The curtain principle - real ownership can be hidden behind title ( i.e trust ownership need not be declared).
and
3.The insurance principle. - the owner of the registry is liable.
