Mortgage Home Loan Settlement

My Grandfather registered our house site in 2001 and took home loan of Rs. 2L in 2001 by mortgaging title deed papers in SBI. My father is also added as co applicant. He paid the installments till 2004 and due to financial losses he stopped paying dues. SBI moved to court and we got notices till 2007 and after that we didn\'t got any notices from bank. My grandfather died in 2007. I don\'t know all this information until I tried to register this house on my name and looked for link document (That is mortgaged in the bank). Now my query is, 1) Is there any way to get a bank loan without that link document. (Because it\'s 2020 and last transaction is in 2001, I have true certified copy of the registration document, EC is very clear that no transaction has done) 2) Suppose if I go for settlement of that loan, how much probably I need to spend to close the loan and get our papers back. Loan details are : Suit filed on 27/12/2004 Suit amount: 2,63,517 Interest : 12% (Bank manager said its monthly compounding and 2% penalty) As Primary applicant (My grandfather) died and co applicant don\'t have any income source to pay off, how much maximum settlement I would get. How courts work in this regards. What will happen if another co applicant (my dad) also got deceased. The loan will pass to me or they will consider it as bad debt and cancel the loan. Thanks you in advance for your help
