What is a CFA? A CFA is defined as: ‘An agreement with a person providing advocacy or litigation services which provides for his fees and expenses, or any part of them, to be payable only in specified circumstances.’ CFAs typically make provision for the payment of a success fee. This is defined as follows: ‘A conditional fee agreement provides for a success fee if it provides for the amount of any fees to which it applies to be increased, in specified circumstances, above the amount which would be payable if it were not payable only in specified circumstances.’ For discussion of success fees, see the section ‘Success fees’ below and Practice Note: Conditional fee agreements—success fees. Note, there are specific provisions (including in relation to success fees) applying to a CFA in the context of personal injury, clinical negligence and mesothelioma cases, which are not dealt with in this Practice Note. For these provisions, see: PI and clinical negligence developments—overview and Practice Note: Conditional fee agreements after 1 April 2013—personal
