How to Draft Your First Expert Witness Report

One of the key functions of an expert witness is to draft an expert witness report.  There is generally no strict requirement for a particular expert witness report format.  A typical expert witness report example may contain:

1.       The expert witness assignment (i.e. the role of an expert witness in the case at hand).

2.      The expert witness’s qualifications.

3.      A description of the expert witness’s document review, research, & investigation.

4.      The expert witness’s opinion.

For civil cases in Federal Court, expert witness reports must comply with Federal Rule of Civil Procedure 26(a)(2)(B) and contain:

(i)  a complete statement of all opinions the witness will express and the basis and reasons for them;

(ii) the facts or data considered by the witness in forming them;

(iii) any exhibits that will be used to summarize or support them;

(iv) the witness’s qualifications, including a list of all publications authored in the previous 10 years;

(v) a list of all other cases in which, during the previous 4 years, the witness testified as an expert at trial or by deposition; and

(vi) a statement of the compensation to be paid for the study and testimony in the case.
