Presenting And Challenging
Expert Witnesses Post-Sanchez

Sessions Closed!




In its landmark decision, People v. Sanchez, the California Supreme Court established new and significant limits on the ability of experts to testify to hearsay statements they relied on to form their opinions. Sanchez has been called, “the most impactful California Supreme Court decision on evidence in the last decade.” Sanchez represents a seismic shift away from allowing experts to serve as the conduit for otherwise inadmissible hearsay. Nearly every family law case involves expert testimony regardless of its size or complexity. Whether you litigate or mediate, you need a foundation for determining what evidence is admissible and what is not.


Experts routinely testify in child custody and domestic violence proceedings, and with respect to financial matters, business valuations, income for support, pension valuations, deferred compensation, and property valuations.


This course will be taught by Justice Mark Simons and Judge Thomas Trent Lewis. They will present an in-depth analysis of Sanchez, including why family law cases are not exempt and what types of hearsay experts may still rely upon in presenting their opinions. Don't be the only lawyer in the case who doesn't understand Sanchez. This is an evidence program you will not want to miss!
