An Evidence Affidavit under Section 138 of the Negotiable Instruments Act (NI Act) is a legal document used in cases involving dishonored cheques. Section 138 of the NI Act deals with the offense of bouncing a cheque due to insufficient funds. An Evidence Affidavit is a sworn statement provided by the complainant or the payee to the court. It serves as crucial evidence in such cases, outlining the details of the dishonored cheque, the transaction, and the legal grounds for the complaint. This affidavit is vital in establishing the prosecution’s case and proving the guilt of the drawer of the dishonored cheque.
