Definition of an Expert Witness

According to the Expert Witness Institute, an expert is “anyone with knowledge of or experience in a particular field or discipline beyond that to be expected of a layman.” An expert witness makes their expertise available to a court or legal body, helping it understand key issues and make informed judgments. In veterinary cases, this means providing professional opinions on standards of care, treatment protocols, and animal welfare practices.

  • Review medical records and case details to assess claims.
  • Provide written opinions, depositions, and testimony in court.
  • Help resolve disputes before cases go to trial.
  • Clarify conflicting claims in lawsuits involving animals.

Their expertise can influence case outcomes, ensuring that legal decisions are based on factual, science-backed evidence rather than speculation or emotion.
