How to recover personal loan amount in case borrower dies?

Dear sir/madam , This is with regarding to my brother . He has taken personal doctor loan from a private NBFC of around 12 lakhs in 2014 n repaid only 2 lakhs . After which he died due to Suicide due to personal problem in July 2017. He had taken loan in Delhi while working there and he is from mangalore , karnataka and as per our knowledge the loan did not have guarantors or any collateral too. . He was single and he does not have any money or property left behind him in his name. In his permanent home in mangalore , only dad lives in his own home (self constructed non inherited) n his mom expired few years back . His dad Retd in karnataka . So far the finance people have not contacted his permanent address even though the last EMI was paid in November 2015. My doubts are as follows 1.Is the personal loan written off because the borrower is dead ? 4. What are the problems which can arise now because of non payment of remaining loan amount?
