I had a verbal agreement with someone and i was supposed to receive money from them, in exchange for which they gave me two blank cheques. Now they have refused to pay me, so can i deposit these cheques in bank one after the other to make it bounce and take legal action? But I do not have any invoice to prove the outstanding balance. Because the person said he does not have money in account, there is no point in depositing. However, it’s been months now and i want to threaten him with legal action. Please advise.
