Constructive trusts in English law
Constructive trusts in English law are a form of trust created by the English law courts primarily where the defendant has dealt with property in an "unconscionable manner"—but also in other circumstances. The property is held in "constructive trust" for the harmed party, obliging the defendant to look after it.
