What is the test for appointing a receiver in a civil action?

564, subd. (b)(9).) "In a civil action, a receiver is an agent and officer of the court, and property in the receiver's hands is under the control and continuous supervision of the court." (People v. Stark (2005) 131 Cal.App.4th 184, 204.) "[T]he appointment of a receiver is a drastic remedy to be employed only in exceptional circumstances. . . . '[R]eceivers are often legal luxuries, frequently representing an extravagant cost to a losing litigant.'" (City and County of San Francisco v. Daley (1993) 16 Cal.App.4th 734, 744.)
