1. It appears that the Bank has issued Possession Notice u/s 13(4) of SARFAESI Act,2002 and after some time shall apply before the local DM u/s14 of the Act to take physical possession of the said property in order to sale the same to recover the outstanding amount standing in the loan account of the defaulting borrower.
2. the claim details willnopt be mentioned in the Possession Notice but in Demand Notice u/s13(2) of the Act which the bank has already issued.
3. You have been clearly dupes by the seller who is the defaulting borrower.
4. Your sale deed registered is invalid in the eyes of law.
5. So, do not pay the bank anything in the said loan account of your seller since that act of yours will not make your sale deed valid.
6. Only in one way you can get rid of the problem i.e. if you repay the entire loan of the seller and the bank issues you a NOC with back date (i.e. prior to the date of registration of the sale deed), then your said registered sale deed can be treated as valid.
7. I have strong doubt whether the Bank will issue the back dated NOC and will return the original link deed to you or not on receipt of the balance amount but with out taking the said NOC and link deed, do not pay anything to the bank.
