Summary

The bill replaces Section 490.065, setting new standards for expert testimony in civil, juvenile, family, probate and non‑jury cases, and establishing a Daubert‑type test for all other actions. It defines who qualifies as an expert, what data must be reliable, limits opinions on a defendant’s mental state in criminal cases, and allows land owners to testify about market value. The changes aim to make expert evidence more reliable and consistent.
