Mrs Claire Berrington MEWI

I have over 18 years’ experience as a Forensic Accountant having given evidence in Court in both civil and criminal litigation, being familiar with the pressure and demands that legal process can impose. I am a FCCA and became a member of the EWI in May 2009. I have found the organisation to be helpful, providing sound advice and support. I would like to put my experience and professional expertise to the benefit of fellow members. My business, Integrity Accounting and Forensic Solutions, founded in July 2013 has been recognised by a Global Advisory award ‘Boutique Forensic Accounting Firm in 2020’

Throughout my 40-year career I have been involved at management and director level with primary responsibility for accountancy and tax matters, training of staff, career development and financial management of practices, so I am comfortable with working at board level and providing support and advice at all levels.

I am passionate about the importance of justice for all and believe that my role as an expert witness is to firstly identify the matters of contention, and to assist the Court in understanding those contentious issues to achieve a fair and accurate conclusion. This includes working in partnership with other experts, resulting in an early resolution of the dispute.

Unfortunately, in recent times expert witnesses have been headline news for all the wrong reasons and therefore I strongly support the use of the EWI to ensure that members are comprehensively trained with resources available to them, fully understand their role, and uphold the high standards required of expert witnesses.

Mr Richard Taylor MEWI

I have been practicing as an expert witness for over 30 years. I have had the experience of working within criminal, civil and family courts, as well as arbitration and mediation hearings both nationally and internationally.

During my last 12 months on the Membership committee of the IEW I have enjoyed both the work and the interaction with the other members of the committee.

I am personally committed to the development of expert practice and the development, maintenance, and training of the expert in practice. Although it must always be acknowledged the enormous breadth of specialisms and diversity within the purview of ‘expert witness’ it always strikes me at the universality of many of the requisite skills and standards of practice. A good expert demonstrates certain attributes and knowledge regardless of their subject, that illustrates and demonstrates to me the fundamental importance and relevance of the work of the institute.

My personal ambitions for the institute include enhancement of its reputation and relevance, in combination with the further development of membership benefits.
