Signature forgery refers to the act of falsely replicating another person's signature.
Methods
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.{{cite book|last=Jackson|first=Andrew R.

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.
