As per the above facts of statement The very first way is You can file a criminal suit against your friend .The borrower must show that the person borrowed the money and committed a criminal act of breach of trust. He can therefore file a lawsuit under Section 420 of the IPC because the person he had to lend them money to defrauded him, as well as under Section 406 of the IPC for Criminal Breach. If the court finds the defendant guilty, he will be sentenced to prison and will have to pay back the money he borrowed.
The second is Settlement outside of the court -The lender has the option of choosing an out-of-court settlement through Lok Adalat, arbitration, or conciliation to recover the money owed. It is among the quickest and most affordable methods of healing. Both parties must be willing to present themselves at the hearing in order for there to be an out-of-court settlement. The parties are typically heard by the arbitrators before the decision is made. If the award is lawful or the recipient cannot pay back the money within the allotted time, they may not appeal after the decision has been made.
And thirdly File a recovery suit under Order IV of CPC if you have any proof by which you can establish in court that you lended him money. If you don't have any proof, try to collect one by any means, videography, text messaging, telephonic conversation etc. Just make him say that he took money from you in cash.
But, there are some other ways too
1. Try talking to his family members that you are in urgent need of money (show some medical emergency etc.) and how he is not giving you your money back.
2. Discuss your problem with a person to whom both of you know and to whom he respects a lot (any elder person or someone like that).
3. Ask him to pay any amount, like 1 lakh or 50k or whatever you can take from him. (Something is better than nothing).
