Expert witness best practice

New edition of guidelines.

04 October 2021

The BPS has published the fifth edition of its best practice guidelines for psychologists who may be called as expert witnesses. Developed by the Expert Witness Advisory Group, under the society's Practice Board, the document outlines the role of expert witnesses, settings where expert witnesses may be called, and other considerations for psychologists who work in this area.

It points out that psychologists working as expert witnesses should be competent to offer an expert opinion to court and should be trained to do this. It also gives an overview of what psychologists who are asked to be an expert witness, or who receive instructions, need to keep in mind – for example discussing the time frame for any work to be done and clarify terms including payment and fees.

The document also covers conflicts of interest, confidentiality, appearing at court and practical and financial considerations.
