Classes of title describes the categories of ownership recorded by the land registry, indicating the strength and quality of a registered proprietor’s title to land.In England and Wales, and Northern Ireland, the concept is set out in land registration legislation and practice rules. The main classes for freehold are absolute, possessory and qualified (and, in England and Wales, good leasehold for leasehold titles). Each class reflects different levels of security, the extent to which prior interests are investigated or guaranteed, and the risk of challenge. Lenders, buyers and conveyancers assess class of title when advising on marketability, due diligence and indemnity insurance.In Ireland, the Property Registration Authority also uses classes of title (including absolute, possessory and qualified), with similar practical implications for conveyancing, title investigation and enforcement of security.In Scotland, the Land Register does not use the same statutory classes of title terminology; instead, it records a single registered title, with any limitations or competing rights reflected in the title sheet and burdens. However, Scottish practitioners sometimes use “class of title” descriptively when comparing the security of different registered titles across jurisdictions.
