Parties may agree all or part of the costs before or after the court has become involved in the detailed assessment proceedings. An interim or a final certificate can be issued.
In the course of proceedings a receiving party may claim that the paying party has agreed to pay costs but will neither pay those costs nor join in a consent application. The receiving party may apply under Part 23 for an interim or final certificate to be issued. The application must be supported by evidence and will be dealt with by a Costs Judge.
