Exploring Lay Opinion Testimony: What You Need to Know

Definition & Meaning

Lay opinion testimony is a type of evidence presented in court by a witness who is not an expert. This witness shares their personal opinions or inferences based on what they have seen or experienced. According to the Federal Rules of Evidence, specifically Rule 701, such testimony is permissible if it is based on the witness's perception and helps clarify their testimony or determine a relevant fact. This allows lay opinions to sometimes provide clearer insights than raw data alone.
