What Is a Psychological Expert Witness?
A psychological expert witness is a qualified professional with specialist training in psychology and clinical assessment. They provide independent opinion evidence on mental health, cognitive functioning, behavioural patterns, and related issues that are beyond the knowledge of a layperson.

Our psychologists can conduct assessments and prepare reports across a broad range of areas, including:
