In When is a Handwriting Expert Not a Handwriting Expert? handwriting expert witness Dennis Ryan of Applied Forensics, LLC, writes:
A handwriting expert is not a handwriting expert when they are called on to examine aspects of a document that do not require a handwriting examination. Most handwriting experts are actually Forensic Document Examiners (FDE’s). The expertise of a Forensic Document Examiner goes well beyond the examination and comparison of signatures, hand-printed or handwritten items.
The Forensic Document Examiner (Handwriting Expert) can examine documents to determine if they are forged. For example, our FDEs have examined documents associated with a vintage automobile sale. The documents that were produced in the sale of the automobile were the window sticker, the bill of sale and other related documents. The price of the automobile was increased by a hundred thousand dollars ($100,000) when these documents were used in the sale of the automobile. Our examiners determined that the documents were fraudulent because they were produced using a color laser printer/copier. The documents appeared artificially aged.
