What needs to be clarified
Compare the disputed signature with verified samples, assess consistent movement features and test whether the narrow field could explain observed differences.
Materials to prepare
- Original form with disputed signature and intact margins
- Naturally occurring signatures from a similar period on different documents
- Requested samples in comparable fields with a collection record
What to compare
Assess the quantity and quality of features. Compare element structure, connections, movement sequence, proportions and placement against field boundaries. Examine variation in verified samples and consistency of similarities and differences, including shortening of the flourish near an edge.
Possible outcome of the analysis
A reasoned writer assessment or an inconclusive opinion may include feature illustrations, discussion of space constraints and additional materials needed.
Limits of the conclusions
Small size does not prove imitation. A short, simplified signature may be uninformative; its shape cannot establish a diagnosis, personality or signing circumstances.
