Rtgs payment issue

I made RTGS to party X 9 lac amount , on 2015 , Now I am in mood to file a case against him, Coz , he has given me some part in cash , only 1.5 lac, still 7.5 lacs are pending. Now I don't want to bear any burden, so Can file suite against him, As I read some of the topic, above that once we proved that he has taken amount for what reason , then only we can file. I want to ask why I need to prove that I gave payment 9 lac, my entry is as it is STAND today also against him. 1st QS. May I file criminal case against him or only CIVIL. What are the remedies for him ...from the court ... How long my case will go??? Definitely , once I send him legal notice , he can't deney coz of bank RTGS enrty through NO 1. So he will have to accept Is there any situation ,he may deny?? Note*:- No, I have not received any amount neither from cheqe nor RTGS so far. Note *:- I don't want interest , as I want only my principle amount. Case belongs to khurja city, Dist Bulandshar , state UP. 203131.
