18. Experts and Expert Evidence

This chapter focuses on the role of experts in civil actions. It considers when expert support is needed—whether as part of the evidence submitted in the action or as part of the advice sought to prepare the client’s case or perhaps for both situations. It discusses the role that the expert will take in both of the situations identified; when permission of the court is needed to engage and submit expert evidence in the action; the need to provide a cost estimate of using an expert and the costs consequences for the client in engaging expert evidence; the management and suitable direction of steps taken in advising clients and proceeding with an action to meet the court’s overall discretion to control the evidence; and the important matters to consider in engaging an expert and in managing several experts in a case.
