Section 58(1) of the Courts and Legal Services Act 1990 provides that a conditional fee agreement is not unenforceable if it satisfies certain conditions. These include conditions to be specified in regulations under section 58(3) of that Act. Regulations 2 and 3 specify those conditions. Regulation 2 applies to all conditional fee agreements. Regulation 3 sets out further requirements applying only to agreements which provide for success fees.
