Under their equitable jurisdiction, courts have significant latitude in how it decides to satisfy any equity established on the basis of estoppel, and does not merely have to defer to what the claimant of the equity asserts as their entitlement

Much like the doctrine of promissory estoppel, a proprietary estoppel argument can only be used as a defence in legal proceedings where another party is seeking to assert their right over land to the detriment of the party who would seek to claim a right by estoppel

Courts have the responsibility to way up the conscience of all parties in situations where one is claiming an equity by estoppel and is not obligated to reward a party where they have detrimentally relied on an assurance that is subsequently withdrawn

Proprietary estoppel and the constructive trust are both doctrines that inevitably lead to the creation of a beneficial interest in favour of a party to remedy unconscionable behaviour and a detrimental outcome

A successful rights claim on the basis of proprietary estoppel leads, by default, to a property right that is enforceable against third parties
