Typical scenarios within this site’s subject: questions to ask, materials to prepare and points that can be examined.
Typical scenarios
If a disputed signature was written on paper but references used a tablet stylus, line differences may reflect surface and capture conditions. In this typical case only images from an electronic document are supplied. Determine which writing features remain and which data are absent.
Typical scenarios
If a handwriting report links uneven strokes only to simulation, it may overlook normal variation, unfamiliar support and writing conditions. Several explanations may be possible, so the specific materials are examined in full, preserving information about their provenance and preparation conditions. The proposition to be tested is defined before comparative assessment of the features.
Typical scenarios
If a disputed statement consists mainly of numerals, the proposed writer’s ordinary letters may not represent how those numerals are formed. Several explanations may be possible, so the specific materials are examined in full, preserving information about their provenance and preparation conditions. The proposition to be tested is defined before comparative assessment of the features.
Typical scenarios
If a disputed signature occupies a narrow field, its size and ending may differ from signatures on blank paper. That alone does not explain its origin. The original and suitable samples are needed to assess ordinary variation and space constraints.
Typical scenarios
If signatures in both a contract and its appendix are disputed, a single question may leave some objects unexamined. Suppose there are several disputed entries, while the reference signatures come from different periods.
Typical scenarios
If a disputed signature belongs to one period and all reference signatures were made much later, the comparison set needs separate assessment. Changes in a habitual signature, writing conditions or the writer’s condition may affect comparability, but do not themselves prove forgery.
