House kudki

Hello Sir

My parents bought  a house long back which the previous owner had taken some loan from bank. And he escaped.

The original papers are with the bank. 

Now bank asked my parents to return the loan. My brother deposited some amount and later he stopped.

Now bank want to do house kudki. They have told, if house goes in kudki all the money will be given to previous owner account.
If my parents deposit the money, original house papers will also go to previous owner.

My parents are very old and they are in big trouble. Is there any solution for this problem.

Please advice.

Thanks
