A Quistclose trust is a trust created where a creditor has lent money to a debtor for a particular purpose. If the debtor uses the money for any other purpose, then it is held on trust for the creditor. Any inappropriately spent money can then be traced, and returned to the creditors. The name and trust comes from the House of Lords decision in Barclays Bank Ltd v Quistclose Investments Ltd (1970), although the underlying principles can be traced back further. (Full article...)
