This chapter focuses on the regulatory aspects related to TPF in the wider litigation market, and purports to improve its social desirability. It does so both by recalling some regulatory issues already in place that do (or potentially could) have an impact on TPF, and by discussing other potentially desirable measures that may foster its use from a broader social perspective. In particular, it discusses some sector-specific regulation on TPF and on third party funders, and other regulation (concerning, for instance, litigation, arbitration or other) having an impact on the TPF practice. It concludes by discussing some more general policy measures on the funding of public litigation and other.
