Due to the great importance of signature in proof, the rules of proof in general do not accept customary documents unless they are signed. The unsigned documents are only accepted as a principle of proof in writing that requires other evidence. The court’s acceptance of electronic contracting requires an authoritative acknowledgment of the electronic signature and its reliability as evidence in disputes Evidence laws required, in addition to substantive conditions, formal conditions, as the signature on paper documents was limited to signature, stamp or fingerprint. This means that any other form has no effect. However, due to the importance of electronic transactions in our contemporary time, the growth of electronic commerce and the emergence of new concepts such as electronic government, the legislation of countries has organized the electronic signature and granted it authenticity in proof within objective conditions.
