The word "title" in relation to land (immovable property) may be understood as a right to the ownership of land and to prove title to land involves production of evidence to prove such right. In a conveyancing transaction, the parties will usually agree that the vendor shall prove good title to a property. The obligation is therefore on the vendor to prove that his title to the property is good. In brief, under the relevant sections in the Conveyancing and Property Ordinance, a purchaser is entitled to require a vendor to prove title by producing title deeds and documents relating to the relevant property going back at least 15 years from the present sale and purchase. A purchaser will, through his solicitors, approve title by inspecting the title deeds and documents supplied, and (where necessary) raising requisitions on title with the vendor's solicitors.
