the owner, as in the Private Conveyancing system. All of the necessary information regarding ownership is on the Certificate of Title. Indemnity principle – provides for compensation of loss caused by private fraud or by errors made by the Registrar of Titles. Background Common law At common law, the vendor of land needs to show his or her ownership of the land by tracing the chain of ownership back to the earliest grant of land by the Crown to its first owner. The documents relating to transactions with the land are collectively known as the "title deeds" or the "chain of title". This event may have occurred hundreds of years prior and could have had dozens of intervened changes in the land's ownership. A person's ownership over land could also be challenged, potentially causing great legal expense to land owners and hindering development. Even an exhaustive title search of the chain of title would not give the purchaser complete security, largely because of the principle, nemo dat quod non habet ("no one gives what he does not have") and the ever-present possibility of undetected outstanding interests. For example, in the UK Court of Chancery case Pilcher v Rawlins (1872), the vendor conveyed the fee-simple estate to P1, but retained the title deeds and fraudulently purported to convey the fee-simple estate to P2. The latter could receive only the title retained by the vendor—in short, nothing. However, the case was ultimately decided in favor of P2, over P1. The courts of equity could not bring themselves to decide against a totally innocent (without notice) purchaser. The common-law position has been changed in minor respects by legislation designed to minimize the searches that should be undertaken by a prospective purchaser. In some jurisdictions, a limitation has been placed on the period of commencement of title a purchaser may require. Deeds registration The effect of registration under the deeds registration system (also known as "record title") was to give the instrument registered "priority" over all instruments that are either unregistered or not registered until later. The recording of the deed served to give notice to the world of the conveyance of title to the grantee named in the deed. The basic difference between the deeds registration and Torrens systems is that the former involves registration of instruments while the latter involves registration of title. Moreover, though a register of who owned what land
