The value of an expert witness goes beyond credentials. Their ability to clearly communicate complex ideas and withstand the demands of trial is just as critical. Preparing them well is essential to building a strong, persuasive case.
5 Steps to Set Your Expert Witness Up for Success
Here are a few key considerations to help ensure your expert is ready to contribute effectively:
1. Prioritize Familiarity with the Record
Encourage your expert to take the time to thoroughly review the case file. Beyond their own analysis, they should be familiar with relevant deposition testimony, exhibits, and opposing expert opinions. The goal is to ensure they’re speaking from a position of confidence built from a comprehensive understanding of all pertinent case materials.
2. Focus on Communication, Not Just Credentials
Jurors and judges aren’t specialists. Even the strongest opinions will fall short if they aren’t clearly communicated. Work with your expert to translate technical concepts into accessible, plainspoken language. Clarity builds trust—and trust is what persuades.
3. Run Mock Examination Sessions
There’s no substitute for practice. Walking through direct and cross-examinations in advance can help your expert refine their delivery and prepare for difficult questions. These sessions don’t just build fluency—they also surface potential vulnerabilities that can be addressed before trial.
4. Emphasize the Importance of Demeanor
How an expert carries themselves on the stand matters. A calm, measured presence can reinforce credibility, especially under cross-examination. Encourage your expert to take their time, answer thoughtfully, and stay grounded—even when the pressure rises.
5. Align on Strategy and Scope
Finally, ensure your expert understands how their testimony fits within the broader narrative of the case. Their role isn’t just to inform—it’s to support a specific position. A well-aligned expert brings clarity and focus, helping the fact-finder connect the technical to the legal.
When an expert is well-prepared, they don’t just answer questions—they enhance the credibility of your entire case. A measured, strategic approach to preparation helps ensure they show up as a true asset at trial.
