Digital Evidence & eDiscovery Law Practice in Nigeria

Chapter 40

Duties and Responsibilities of Expert Witness

An expert witness is typically hired and paid by one of the sides in a legal dispute, but the fundamental responsibilities of the expert are to the court. The expert is sworn ‘to tell the truth, the whole truth, and nothing but the truth’, not “only those truths that help his client”. In addressing this responsibility, Chapter 40 brings to focus the constituent of this duty.
