For CP-SIIG’s service providers to maximise the evidential potential of a document it is very important to submit the original questioned document for examination wherever this is possible. If the original is not available, the best quality, earliest generation copy should be submitted and it may well still be possible to reach a useful finding, albeit likely a qualified finding.
The specimen signatures and/or handwriting should also, where possible, be in original form and should ideally consist of two classes of documents: samples written during the normal course of business, some of which should be contemporaneous with the questioned material; and samples written specifically for the purposes of comparison.
Specimens should not be excluded simply on the basis that they are not original or not of similar date to the questioned document. The more specimens provided to CP-SIIG the better in terms of providing comparison material for an examination.
