Buying auction property under sarfaesi act

My client is interested in a bank auction property being auctioned under the Sarfaesi Act. The bank sells on as-is-where-is-what-is basis. In case there are outstanding dues of the IT / GST/ Customs / BMC property tax, then please advise: a) in the case where any of the agencies have pasted attachment notices or b) there are no attachment notices , but the outstanding dues notices are pasted on the premises does my client have to clear the dues of the agencies who have outstanding dues? Can we insist on the bank to provide an indemnity against any other outstanding dues. Please advise Ashok Pachisia 9867297925 pachisiaa@gmail.com
