What is Document Examination
In order to establish that a questioned signature was written
by a particular person, an examination with known genuine signatures must show substantial agreement in sufficient handwriting characteristics to identify the author and eliminate the possibility of any other writer.
The handwriting characteristics that are evaluated include:
- line quality
- pressure patterns
- rhythm
- slant
- size and proportions
- utilization of space and spatial alignment
- initial and terminal strokes
- writing speed
- legibility
- skill level
- letter forms
- types of connectors
- method of construction
- pattern formations
Any significant unexplainable differences will be sufficient to eliminate the writer. When there are significant differences between the questioned signature and the known signatures then an opinion can be formed as to the authenticity of the signature. Natural variation is expected in the authentic signatures, as you can never sign our name the same way twice in your entire life time!
After making optical enlargements and comparing these handwriting characteristics then an opinion can be given, verbally and/or as a letter of opinion.
The business of Document Examination is a never ending practice of study and continued learning that requires dedication and passion to speak for the documents and the evidence they reveal.
