Can a party demand the exchange of expert witness information by all parties?

Code of Civil Procedure section 2034.210 permits a party to demand the exchange of expert witness information by all parties. The parties must simultaneously exchange expert witness information for any expert that the party expects to call at trial. (Code Civ. Proc., 2034.260.) If a party unreasonably fails to designate an expert, the opposing party may object and the trial court must exclude from evidence the expert's opinion testimony. (Code Civ. Proc., 2034.300; see also Richaud v. Jennings (1993) 16 Cal.App.4th 81, 88-90.)
