What's most important in the study of handwriting is the concept that no two individuals write alike. This is a very important concept in forensics, because it adds individuality to the investigation. What we look for are the individual's handwriting style. Variations of slope, speed, pressure, spacing, pen movement, writing skills, finger dexterity, margins, grammar, and things of that nature. All those in combination, will lead to a determination as to whether one, and only one, individual did or did not write this specific document.
