Dear sir we sold a piece of land on 18th of september 2013 in which we would get rest of the payment within 3 months. But the builder was not able to make us the payment and again went with the in an agreement on 8th feburary and this time the payment was to be done on 8th of may 2014 . He gave us around 20 lakhsbut now the builder is saying he will pay the rest money today and hasn't paid the rest amount of money . due to this delay we already have inoccured the loss of around 6 lakhs due to delay . So what are my legal options against him .
