Hello Team, In fact my acquittance borrowed Rs 450000(Rs 3 lakhs)through bank transfer and the rest through the piled up Emis which are not paid after the condition mentioned by him which states that he would pay the required emi on an every month basis. The said amount was transferred to him by the way of Loan which did get sanctioned in my name. The said Condition is not followed by him,at that time he was employed in a multi national and now he is jobless,he has given me 4 blank cheques . Moreover he stays in his own house at Nehru Nagar Bangalore where it is acquired through a way of will from his great grand mother to his father who is the owner of this property. Now he is not heading to any verbal communication.How to go ahead with the recovery?What are the legal steps?Can I present his cheques? What are the procedures?
