There are a multitude of types of evidence: statements by parties, evidence via experts in a particular field, and demonstrative evidence, among many others. Demonstrative evidence is often key to winning a particular case.
Demonstrative evidence is diagrams, objects or photographs. It is said a picture is worth a thousand words. In many, many cases, a photograph taken at the time of an incident or shortly thereafter is of immense importance. This is often key to showing a negligently maintained condition or property or the extent of damage to a car or bruising to an individual to demonstrate an injury to a particular area of the body. In any event, this is a particular area in which a client can do very much to assist themselves in a successful claim. Take a picture. Take several pictures from close up and a distance. Have a relative take a picture on or as soon after an accident as possible. Attorneys should visit a scene after an accident to determine any changes in condition and obtain those same photographs, potential witness availability, etc. that may be demonstrated by a visit to the scene. In the absence of evidence from a client this is often a crucial first step in pursuing a claim successfully. In summary, the best evidence to start many cases is a simple photograph taken by the client that preserves “evidentially” the key to winning a case years down the road and through the adversity of defense witnesses and lawyers.
