Rental aggrement

I ENTERED AN UNREGISTERED RENTAL AGREEMENT IN THE MONTH OF APRIL 2014 FOR FIVE YEARS TO RUN AN INDUSTRY.ACTUALLY THAT BUILDING WAS UNDER MORTGAGE WITH A BANK. THE MATTER WAS SUPPERESED BY THE BUILDING OWNER. THE BANK TOOK POSSESSION UNDER SURFASI ACT,AND SEALED THE SAME IN THE MONTH OF FEB 2015. MY MACHINERIES ARE INSIDE THE BUILDING.. HOW COULD I GET THE MACHINERS, AND COMPENSATION FOR THE LOSSES FROM THE OWNER OF THE BUILDING.
