1. Defenses - demand notices were not received ( though they were received). Bank can easily demolish this defense if it can show that notices were duly served and received by borrower. Another defense is that npa was wrongfully declared. Again that won't stop the public auction. If u succeed then the auction sale can be reversed. But auction won't stop unless full dues of the bank are paid with auction expenses incurred so far
2. Completely your wish. Lawyer is not a magician that somehow magically he will get the auction stopped. He can only submit your legal defenses against the auction which the DRT will decide
3. If you can somehow manage the bank then may be
4. Obviously by making payments to the bank of the demanded amount
5. Yes if you pay up their dues
6. You can give a OTS or a one time settlement and request for debt restructuring. But giving an ots offer means acknowledging the dues of the bank and accepting that as correct
7. Try and approach the bank. The bank can in place of auction go for a private treaty where from the sale price agreed with the buyer the bank will require that its dues be directly paid by buyer to the bank and balance can be paid to borrower by buyer
8. Once magistrate passes an order for possession then the bank will move immediately and take possession with help of police assistance. The bank will then issue a sale notice by auction of 30 days. So you still have 30 more days to pay the dues of the bank. If you pay them then the bank will not conduct the public auction. So it would be in your interest if you tell your buyer to pay the sale price fast so that the property does not go to any third party in public auction
Best way to approach - it's common sense! PAY THE DUES OF THE BANK AND REDEEM YOUR PROPERTY! I DONT THINK THAT IS SO DIFFICULT TO COMPREHEND
Other questions asked are similar questions though in different ways. You are just running round the Bush and wasting time. It would be prudent to expedite the completion of sale with your buyer and from sale proceeds pay the 60 lacs plus other charges of the bank and claim back your property. Approach the bank and inform that you have found a buyer for Rs 2.2 crore and from that he can directly pay the dues of the bank and balance will come to you. The bank will willingly agree for private treaty as its auction expenses would be saved and it also gets it money back. What the bank ultimately wants is its money. Whether its through public auction or private treaty just doesn't matter. Think practically and rationally. It's not your case that the bank is wrongfully demanding the money from you. You seem to have acknowledged the bank's dues.
Hope this helps
