Opinion Evidence (Lay Witnesses) (F.R.E. 701) (revised 2017) is a type of evidence presented in a court of law which consists of the testimony of a witness who is not an expert in the field. Lay witnesses are any individuals who have direct knowledge of the facts or evidence in the case, and can provide testimony based on what they have seen, heard, or experienced. Lay witnesses can provide opinion evidence as to the credibility of a witness, the existence of a fact, the character of a person, or any other matter that is not within the realm of scientific or technical knowledge.
