8 Key Questions to Ask When Vetting an Expert Witness

Selecting the right expert witness is a critical step in ensuring that technical or specialized evidence is presented clearly and credibly. Whether you’re building a case, preparing for mediation, or assessing a claim, the expert you choose must demonstrate both subject-matter authority and the ability to effectively communicate their expertise to a judge or jury. 

Building Confidence in Your Expert Witness Selection

Here are eight key questions to guide the vetting process:

1. What is the expert's area of expertise, and how does it apply to this matter?

Ensure the expert’s background directly aligns with the facts or issues in question. Relevant, focused expertise is typically valued over broad experience. 

2. What is the expert's professional background and experience testifying?

An expert who has previously testified understands courtroom expectations, procedures and how to deliver opinions under examination. 

3. Has the expert been qualified as an expert in similar cases?

Prior qualifications by a court indicate that the expert witness’ credentials and methodology have been recognized as reliable. 

4. What is the expert's methodology for forming opinions?

Ask how the expert gathers information, analyzes data and develops conclusions. A clear, defensible process adds weight to their testimony.

5. How does the expert communicate complex findings to a non-technical audience?

The most effective experts can explain highly technical topics in a way that is both accurate and accessible to judges, juries, and opposing counsel. 

6. Has the expert ever been challenged or excluded as an expert?

This helps identify potential concerns and ensures transparency about the expert’s track record.

7. Are there any potential conflicts of interest?

Verifying neutrality protects the credibility of the expert and the integrity of your case.

8. How does the expert stay current in your field?

An expert witness’ credibility depends on the currency of their knowledge. Ask about continuing education, recent publications, or professional affiliations to confirm they remain active and up to date.
