I orally ordered for two laptops with third person and gave cheque for Rs.75,000/- .that the cheque should present only after the laptops delivered.but the goods not delivered to me ,I forgotten to take back the cheques, I went to out of country and stayed there for three years and returned to India. I was shocked to know that the third person purchased laptops from a company and deposited my cheque the cheque was bounced so i am attending the court for offence u/s138 of N.I.act. Please suggest me how can I defend myself?
