A comprehensive overview of the rules governing litigation costs in civil proceedings under the Civil Procedure Rules (CPR). They explain the distinction between Fixed Recoverable Costs (FRC), which apply to Fast Track and the new Intermediate Track cases, and Assessed Costs (Summary and Detailed Assessment), which remain standard for complex Multi-Track cases involving higher values. The texts detail key procedural mechanisms designed to manage costs, such as costs budgeting using Precedent H and R reports for Multi-Track cases, and the strict sanctions for non-compliance with filing deadlines. Furthermore, the documents examine inter-partes costs orders (interim and final), the impact of Part 36 offers on costs recovery, and the court’s power to impose liability on third parties through Non-Party Costs Orders and Wasted Costs Orders.
