This paper begins with an overview of third-party litigation financing. It next examines current third-party financing practices in the United States. It then sets forth a critique of the practice, particularly the incentives it creates to engage in frivolous and abusive litigation. In this section, the paper also presents a case study on the Commonwealth of Australia, the first jurisdiction to permit third-party litigation funding, where such funding has dramatically increased litigation and given investors pervasive — even total — control over a plaintiff’s litigation. Finally, the paper proposes that third-party litigation financing be prohibited in the United States to prevent these abuses. At the very least, the paper concludes, such funding should be banned in class actions and other forms of aggregate litigation.
