Sirs
I given a loan to a friend for 37 lakhs. I have no proof written that he took loan from me as he is a friend. He given me a cheque for the amount without writing amount or date or name but only with his sign. I filled in my name, amount and date and deposited in my bank. It came back with insufficient funds message. He is now saying that he never took loan from me and asking me to prove it. What can i do now?
