@Jayaprakash m: Once a member posts a query, another member should not post another query in the post of the original queriest as a matter of discipline and to confine a query to one subject alone.
(If the cheque is returned with such reason first issue notice as per laid down procedure and then depending on his response, you can take a stand. When cheques are sent by post to the payee or through some other mode, it is absolutely not possible to verify the signature of a drawer or his powers. According to my knowledge, the matter is more serious that the malafides are present right from signing the cheque in a different manner. If the cheque according to the drawer is lost or misplaced, he must have countermanded payment, and then the drawee bank reason for return must be "Cheque reported lost" but in this particular case, the reason was "Signature differs". The reasons may be genuine also, as some bankers do not honour cheques even when there is a slight deviation from the decade-old opening form signature, hence the reply to the notice has to be considered before filing a case. Issuing Notice is also mandatory.
