What is a fact witness primarily known for in legal proceedings?

A fact witness is primarily known for testifying based on personal observations and experiences. This role is critical in legal proceedings because fact witnesses provide firsthand information about events or circumstances relevant to the case. Their testimony is based on what they have directly seen, heard, or experienced, which can help establish the facts of the situation being examined.

In contrast, roles that involve expert analysis, opinions, or interpretation of data pertain to other types of witnesses. Expert witnesses typically provide specialized knowledge or opinions based on their expertise, while fact witnesses stick to evidential, factual recounting instead of subjective or analytical commentary. This distinction is essential in court, as fact witnesses support the factual basis of a case without stepping into the realm of expert testimony, which requires extensive knowledge that goes beyond personal experience.
