Expert Witness

What is an Expert Witness?

  • Expert witnesses can strengthen a case by providing credible testimony.
  • A qualified expert understands the importance of agreeing to only work on cases where they have the proper expertise.
  • An expert witness has the responsibility of educating the jury by explaining complex topics in easily understood terms to help jurors better understand the facts.


A case can be undermined by weak expert witness testimony, such as:

  • Communication problems, like providing more information than is necessary to answer a question or using complex technical terms not easily understood by non-experts.
  • Credibility problems, like shaping their opinion based on the lawyer’s case theory, being unprepared, or answering questions beyond their field of expertise.
  • Conflict problems, by taking on a case where the expert does not agree with the lawyer’s side of events.


A qualified expert witness:

  • Will have the knowledge, skill, experience, training, and education and uses reliable facts, data and methodology:
  • To form and express an expert opinion,
  • To help counsel understand the evidence, and
  • To help counsel deal with opposing expert witnesses.
  • Will be comfortable disagreeing with the lawyer that hired then when appropriate so it does not appear that they are there to just satisfy the lawyer.
  • Will be versed in how to testify during challenging questioning by using techniques that provide the opportunity and time to consider a question and provide an intelligent answer.

Best Practices

A qualified expert witness

  • Will be prepared in the process of testifying and how to meet the expectations of jurors.
  • Will ensure the hiring lawyer understands how the expert reached their conclusions, the methodology used and opposing theories.
  • Will practice with the hiring lawyer to improve their planned testimony by using mock trials, practice depositions and question and answer sessions that highlight their opinion.
  • Will have the ability to put together visual aids or other graphics that help inform the jury.
  • Will understand the focus on both body language and verbal communication and how those behaviors can influence a jury.
