What is the test for appointing a receiver in a personal injury case?

" 'The rule is established that the appointment of a receiver rests largely in the discretion of the trial court and that its action in appointing a receiver or its refusal of an application for the appointment of such an officer will not be disturbed in the absence of a showing that the court's discretion has been abused.' " (Elson v. Nyhan (1941) 45 Cal.App.2d 1, 4-5, 113 Cal.Rptr. 474.)
