What is a Testifying Expert and Why Are They Important in Court?
Definition & Meaning
A testifying expert is a specialized individual identified by a party involved in legal proceedings who may provide testimony during a trial. This expert possesses scientific, technical, or other specialized knowledge that can aid a jury in understanding complex issues. The identity of the expert and any documents used to prepare their testimony are subject to discovery, meaning they must be disclosed to the opposing party during the legal process.
