The difference between a receiver and a liquidator, is that a receiver’s main duty of care is to a secured creditor, which is usually a bank, whereas a liquidator is concerned with all of the affairs of a company and all of its creditors.
Receivers seek to realize and secure assets and manage affairs to pay debts. For businesses, receivers seek to maximize profits and asset value, and either terminate operations or sell all or part of the company. When a receiver is appointed, a company is said to be "in receivership."
