Hi,nI'm a UK NRI who has lent 25 lacs to an Indian for a year at 30% per annum. We drafted an agreement and Power of Attorney so that I can possess his land if money and interest is not repaid in 12 months. 3.5 years later I'm still waiting for my money. After listening to his excuses, I finally sent him a notice from UK to pay up.On arrival in India  without us meeting, he filed a court case against me that he does not owe me any money, instead I'm extorting money and unnecessarily threatening himMy questions are:nn1.  Is this 18% maximum interest applicable to seasoned money lenders only or to one off lender (Peer 2 Peer) as well? nn2.  Is it possible to file a case in a district other than the one where both parties reside?nn3.  Is it a crime, like dishonored cheques, to mortgage (ad rehan) land to a bank when it is already secured with a PoA to another individual?nn4.  Is PoA still valid untill loan has been fully repaid and even if it has been cancelled?nnThanks in advance.
