What is the test for an accounting in a personal injury case?

However, "[a] cause of action for an accounting requires a showing that a relationship exists between the plaintiff and defendant that requires an accounting, and that some balance is due the plaintiff that can only be ascertained by an accounting. [Citations.]" (Teselle v. McLoughlin (2009) 173 Cal.App.4th 156, 179.) Here, plaintiffs have failed to allege that a balance is due to them from defendants.
