Sullivan v Sullivan

The case of Sullivan v Sullivan involved a dispute between the plaintiff, Sullivan, and the defendant, also Sullivan, concerning the ownership and occupation of a house. The plaintiff sought to establish that he had an equitable proprietary interest in the house, which entitled him to remain in occupation for life. This claim was based on the defendant's representation that he would be allowed to stay in the house for as long as he wished. The matter was heard in the Supreme Court of Victoria.

The central legal issues in the case were whether the plaintiff could establish the doctrine of proprietary estoppel against the defendant, and if so, what the scope of that estoppel was. The court had to determine whether it was unconscionable for the defendant to renege on the representation that the plaintiff would have a personal right to occupy the house for life. Additionally, the court considered whether the plaintiff's expenditure on the house gave rise to an equitable charge against the property.

The court found in favour of the plaintiff, concluding that it would be unconscionable for the defendant to resile from the representation made to the plaintiff. The representation had induced the plaintiff to believe that he would have a personal right to occupy the house for life, and the court held that this was a clear and unequivocal promise. The court further found that the plaintiff's expenditure on the house did not give rise to an equitable charge but rather reinforced the equitable interest in remaining in occupation. The court's decision was based on the unconscionability of the defendant's conduct in attempting to evict the plaintiff from the house.

The court ordered that the plaintiff had an equitable proprietary interest in the house, which entitled him to remain in occupation for the rest of his life. The court did not grant the plaintiff an equitable charge over the property, finding that the expenditure on the house did not give rise to such a charge. The court's decision was a significant affirmation of the principles of proprietary estoppel and the protection of reasonable expectations in property law.
