When people write, their handwriting changes slightly from day to day and from situation to situation. This is known as their range of variation. We need to establish this range of variation in order to give you the best result possible, and ideally, we would require approximately twelve samples of handwriting and/or signatures either made during an individual’s everyday life or at your request. These should be dated around the same time as the writing in dispute if possible. We can work with less examples than this, although the examination may be limited.
