Hiring the expert witness

learly there are certain technical capabilities that are being sought in an expert for a particular case, but being too narrow in the approach to hiring an expert can make the task unnecessarily difficult. The primary characteristic that should be sought in any expert is the ability to teach – to clearly explain very complex concepts (whether technical, financial, engineering, accounting, etc.) in terms that an informed layman can understand. Judging this ability can often be accomplished in interviews with the potential testifier, but there are other ways to gather even more useful information about potential experts if counsel takes time to evaluate experts. For example, many experts, particularly financial/accounting experts, will offer to provide in-house training programs on a wide variety of topics for no charge or nominal charges. This provides attorneys with the opportunity to evaluate the potential expert’s ability to teach and explain as well as his public demeanour. Experts in a variety of different fields are also frequent public speakers who offer other opportunities for attorneys to evaluate a potential expert’s presentation skills.
