Conversation on mobile phone as an evidence of proff in money recovery lawsuit?

Due to some urgent need ,I had got my cash converted in to cheque by some one.Due to nonawreness i did not take any proff for the cash amount i paid to that person.Now the same person has put a false recovery suit on me in Delhi court saying that he has given me a loan of that amoutn and is using mobile conversation as an evidence of proff.He was also my old insurance broker and there might have been some mobile conversation in such a way that may be used as a conversation representing certain amount due to me.and me mentioning thati will pay them as soon as possible. Can Delhi court take decision based on that and ask me to pay the amount?

Any thing in black %26amp; white alone will prove in any court of law. Suppose if you lose yr mobile and if any body talks over the phone and agrees hell of lot of things is it binding you legally . If so how %26amp;why ? I might or some of my friends might have attend my phone calls and use to talk interestingly as a wrong call ! what will be the result. Why should held responsible for anonymous call.
