This study examines the extent to which “an interest in the proceeds of sale of land” is able to be protected by a caveat, under s 115(3)(a) of the LTA. To this end, the history of the LTA and case law are studied to identify the legislative intent behind s 115(3)(a). Various issues such as the scope of a caveatable interest and lack of definitions in the LTA, among other challenges, are identified and consolidated. This study then proposes the use of the “definite entitlement” test as an extension of the statue for greater clarity.
