California Law Summary
This statute specifies the contents required in a party’s expert witness disclosure. When disclosing expert witnesses, the party must include:
A list of all expert witnesses expected to testify at trial,
A brief narrative statement of the qualifications of each expert,
A brief general statement of the subject matter on which each expert is expected to testify,
The substance of the facts and opinions to which the expert is expected to testify,
A summary of the grounds for each opinion.
Purpose
To provide opposing parties with sufficient information to evaluate the relevance, qualifications, and opinions of each expert witness. This promotes efficient pre-trial preparation and reduces the need for extensive follow-up discovery or surprise testimony at trial.
Application
This section applies when a party serves an expert witness list under Code of Civil Procedure § 2034.210. The disclosure must include all required details in writing, enabling the opposing party to:
Prepare for expert depositions,
Assess the scope and basis of each expert’s opinions, and
Determine whether rebuttal experts or motions to exclude are warranted.
Failure to provide complete and compliant disclosures may result in preclusion of the expert’s testimony at trial, absent a showing of good cause.
