Litigation funding in the United States and European Union will face growing regulatory pressures as increased use is balanced with demands for transparency. The long-awaited introduction of minimum standards for funders operating in the EU remains an ongoing task for the European Commission. Although the Representative Actions Directive includes a safeguard against funding agreements compromising the interests of consumers, the need for clear regulatory structures remains necessary. Measures such as disclosure of funding sources and structures are currently jurisdiction-specific, creating the risk of forum shopping. In the United States, an increasing number of states have placed additional controls on the use of funding. We expect this to continue, with measures likely to include licencing funders and increasing transparency of funder identities, agreements and structures. Efforts to introduce federal legislation, such as the proposed Litigation Transparency Act of 2024, have so far been limited.
