What is an Expert Witness? A Comprehensive Legal Overview
Definition & Meaning
An expert witness is a person who possesses specialized knowledge or skills that exceed those of the average individual. This expertise allows them to provide testimony in legal proceedings on topics that require a deeper understanding. Unlike lay witnesses, expert witnesses can offer opinion testimony, which is crucial in helping the court understand complex issues. To qualify as an expert, the individual must demonstrate their credentials and experience, which are assessed by the court.
