In the course of their opinion-making practice, handwriting experts are bound to face an issue of similar handwriting between different individuals. As there are several types and degrees of such similarities, depending on a particular similarity degree, they may also pose a risk of error. The questioned material itself may present an additional difficulty in the examination process, especially when it is limited to a small number of distinctive features of a low identification value. This article presents a case study, in which an expert encountered a very high similarity between two random, unrelated individuals’ handwriting consisting of short forms of evidential signatures.
