Issue legal notice to your friend to repay your loan 

2) if he refuses file police complaint of cheating , criminal breach of trust against your friend 

3) you can also file suit to recover your money with interest 

You have to file a criminal complaint against him for defrauding you by telling you false stories. A recovery suit must also be filed for the money.

From the facts given, it seems that you do not hold any documentary proof for the loan and the limitation period to recover the loan legally also is lost, unfortunately.

Dear Client,

If you have lent the money in good faith without charging any unlawful interest, then you can file a recovery suit in a civil court having the Jurisdiction to try the suit. However, relevant documents such as an agreement paper, a promissory note, loan agreement etc. will be required in such cases to prove your claim. You can also file for a summary suit under Order 37 of CPC in that case. 

Thank you. 

You need file a civil suit for recovery of money. If you can take a cheque from him and it bounces it will be better to file criminal proceedings. 

Sir, If you need any further assistance.You can approach me through Kaanoon or LinkedIn.

Since you have evidences for the money lent to him and also for the partial repayment of the loan amount, you first issue a legal demand notice to him mentioning the background of this amount borrowed b y him. 

If he is not responding nor complying with the demands made , you may better file a money recovery suit in an appropriate court

- Since, you have paid him the said amount by way of online mode , then on this proof you can claim refund the entire amount from him legally. 

- Send him a legal demand notice for said friendly loan , and if not refund then file a recovery suit before the court for getting the amount with interest. 

- Further, as you are living abroad , then you can give any nearest one to engage a lawyer and to file the said case ,and your presence is not mandatory. 

At the outset issue a legal notice onto him that he repay you within 7 days of receipt of notice, failing which you will initiate civil and criminal proceedings against him. This will give him that little push to come down for a settlement of installments, but only this time get an MoU signed from him agreeing to the terms failing which you can again initiate proceedings against him. If he doesn't adhere to the timelines set by the MoU file a criminal complaint in the police station u/s 420 IPC.
