The purpose of the Torrens system is to facilitate transactions in land. It does so by creating a conclusive land-register, which can be absolutely relied on to provide accurate title information. It therefore follows that claims asserting an unregistered right in registered land must fail, except when a person is precluded from claiming that he has relied on the information recorded on the land-register. Such preclusion occurs when a registered proprietor did not furnish consideration, or took with the knowledge that his predecessor in title did not genuinely consent to transfer to him, or voluntarily undertakes obligations. The mechanics of the Torrens system of centralised land transactions mean that any right concerning land ought to be capable of protection by caveat.
