Common benefit funds (CBFs) ensure fairness and equity in the distribution of legal fees and expenses in aggregate and complex litigation, including class actions, mass torts, trust and securities, and multidistrict litigations (MDLs), where the litigation is prosecuted by either an ad hoc or judicially appointed committee or team of attorneys. Their primary purpose is to recognize and compensate the plaintiffs' attorneys who contribute their time, expertise, and resources to advancing the interests of most, if not all, of the plaintiffs in a particular litigation, including litigants who are not their clients but are benefited by the attorneys' work product prosecuting the suit.
