The article takes up the issue of a different approach to materials being subject to classical document examination and refers to repeatable forms, which have an important function in handwriting analysis. Basing on examinations of writing samples originating from different individuals, an occurrence of a repeatable form departing from the official definition has been observed, i.e. “inverted repeatability”. It constitutes a variation of the traditional repeatable form, i.e. the compared elements are inverted and executed in opposite directions. Below, examples and results of the research work are presented. The very nature of the “inverted repeatability” in classical document examination is emphasized with reference to writing habits and traditional repeatable forms.
