Legal Definitions - lay opinion testimony

Definition: Lay opinion testimony is evidence given by a witness who is not qualified as an expert but who testifies to opinions or inferences.

In simpler terms, it means that a regular person who is not an expert can give their opinion or thoughts about something in court.

For example, if a witness saw a car accident, they can give their opinion on who they think was at fault based on what they saw. This is considered lay opinion testimony.

However, there are limitations to what a lay witness can testify to. Their opinion or inference must be based on what they actually perceived and must be helpful in understanding the case or determining a fact in question.

Overall, lay opinion testimony is a way for regular people to share their thoughts and observations in court, but it must be relevant and based on their own experiences.
