Signature forgery refers to the act of falsely replicating the signature of another person.

Methods[edit]

Several different methods can be used to forge signatures. One method is the "freehand method", whereby the forger, after careful practice, replicates the signature by freehand. Although a difficult method to perfect, this often produces the most convincing results.[1]

In the "trace-over method", the sheet of paper containing the genuine signature is placed on top of the paper where the forgery is required. The signature is traced over, appearing as a faint indentation on the sheet of paper underneath. This indentation can then be used as a guide for a signature.[1]

Detection[edit]

A number of characteristics can suggest to an examiner that a signature has been forged, mostly stemming from the forger focusing on accuracy rather than fluency. These include:[1]

  • Shaky handwriting
  • Pen lifts
  • Signs of retouching
  • Letter proportions
  • Very close similarity between two or more signatures
