A financial expert witness must determine information about the degree of injury in personal injury cases. Therefore, financial experts must:

Make as reliable an estimate of the victim's injuries as possible so that the damage estimates will be as accurate as possible.

Ignore the extent of injuries of the victim and concentrate on financial issues.

Rely on the expertise of others such as doctors so that the financial expert can incorporate that information into the damage model.

Wait until the extent of the victim's injuries can be determined completely so that the case can proceed.
