There are several advantages to having your expert witness talk to the client directly. If your expert’s opinions will be based on the client’s observations and thoughts, the expert should meet and talk with that individual. For example, when the recollection of the plaintiff is crucial to the accident reconstruction expert witness’s opinion, and the plaintiff’s attorney fails to have his own expert meet the client, then the expert must rely on information the attorney gleaned at the deposition. If the expert only sees a summary of the client’s statement or deposition, there is no opportunity for the expert to ask pertinent questions directly.
