The Academy of Experts and HKA publishes new research on expert witness process

An Expert’s Perspective 2026 report provides an expert-led view of how expert evidence is commissioned, prepared, and presented in dispute resolution proceedings.

Drawing on responses from 456 experts and expert assistants across a range of jurisdictions and disciplines, the report explores key stages of the expert process, including appointments, instructions, disclosure, report preparation, expert meetings, witness conferencing, the use of expert assistants, and the emerging role of artificial intelligence (AI).

While the role and performance of expert witnesses is frequently discussed by judges, arbitrators, lawyers, and commentators, comparatively little research has focused on the experiences of experts themselves. The report seeks to address that gap by providing an expert-led perspective on a number of recurring themes arising in contemporary dispute resolution practice.

The research is intended to contribute to the ongoing discussion about how experts, lawyers, parties, and tribunals can work together to support independent, transparent, and effective expert evidence and, ultimately, the fair administration of justice.

“I enthusiastically welcome this paper which addresses a subject of considerable importance to the administration of justice: the role, conduct and practical experience of expert witnesses.

“Quite rightly, this paper does not seek to excuse poor expert practice, or to diminish the personal responsibility of the expert. What this paper does is provide an essential perspective which has too often been absent from the debate: the perspective of experts themselves. Its results benefit from being based on contributions from many experts who work across the world. In so far as is possible, it therefore represents a statistically reliable assessment, rather than being based on the experience of a few self-selected people whose views and experiences may not be representative.

“The merit of the research described in this paper lies in its practical orientation.

“Accordingly, I strongly commend this paper to judges, arbitrators, lawyers, experts and all those concerned with the proper administration of dispute resolution.”

The Rt Hon. Lord Neuberger of Abbotsbury, President of The Academy of Experts and former President of the Supreme Court of the United Kingdom

“Independent expert evidence plays an important role in helping courts and tribunals determine increasingly complex disputes. This research provides valuable insight into the experiences of experts working across a wide range of disciplines and jurisdictions.

“We hope the findings encourage continued discussion across the profession and support the adoption of practices that help ensure expert evidence remains objective, reliable, and of maximum assistance to decision-makers.”

Nicola Cohen, TAE Spokesperson and Chief Executive, The Academy of Experts

“Much has been written about expert witnesses and the role they play in dispute resolution. However, comparatively little attention has been given to the experiences of experts themselves and the practical realities of the expert process.

“This research provides insight from experienced practitioners working across a broad range of disciplines and jurisdictions. The findings highlight a number of recurring themes relating to appointments, instructions, disclosure, procedural timetables, expert meetings, and the presentation of expert evidence.”

The report includes a foreword by The Rt Hon. Lord Neuberger of Abbotsbury, President of The Academy of Experts, and a commentary by Professor Doug Jones OA, providing additional perspectives on the role of expert evidence and its contribution to effective dispute resolution.

In addition to presenting the survey findings, the publication brings together guidance produced by The Academy of Experts covering the role of the expert witness, expert meetings, expert reports, expert witness CVs, and the responsible use of artificial intelligence. Together, the research and guidance provide a practical resource for experts, lawyers, parties, and tribunals involved in dispute resolution proceedings.
