While general witnesses can only testify to facts they saw or heard, experts (like doctors, engineers, or forensic accountants) are allowed to give opinions based on their specialized training.
This affidavit is often used in motions for summary judgment, where the expert explains why the scientific or technical evidence supports one side so strongly that no trial is needed.
It details the expert's qualifications, the methodology they used, and their final conclusions.
