In 2002 my father mortgaged property for Rs.1,00,000/- and handed the documents to the mortgager. Due to some problems in mortgager family our documents were blocked since 2007. Inspite of asking him for our documents since then he is postponing and my father as a friend of him also considered it casually as he knows his problems. My father expired in 2016 and now we have approached the person. My father has not paid any amount since 2002 and the rate of interest is 24% compounded annually. now when we ask the mortgager he is asking us to pay the interest till date as per the document and says that he is not having the document in hand. My mother wants to proceed legally. I would like to know if we approach court will it ask us to pay the complete amount as per the document or will it reduce the rate of interest. another thing is the mortgager is not having my original document since 2007 and he cant produce the original document in court also. please respond to my request as it is the only source for my mother. Also i heard that the mortgage is valid only for 12 years of each repayment
