Lay opinion testimony refers to the expression of personal opinions or thoughts by an ordinary individual in a court setting. Although not an expert, they are permitted to share their perspective based on their observations or knowledge. The court allows this type of testimony only if it contributes to a better understanding of the case. For instance, if a witness witnessed a car accident, they can provide their opinion on who they believe was at fault. However, when it comes to explaining medical matters, only experts in the field, such as doctors, are qualified to do so.
Lay opinion testimony refers to the evidence provided by a non-expert witness who expresses their opinions or inferences.
