National Land Code
"100. Forfeiture for non-payment of sum demanded. The Collector shall not during the period specified in any notice under section 97 accept the tender by or on behalf of any person or body of a lesser amount than the sum thereby demanded; and if by the end of that period the whole of that sum has not been tendered to him, he shall thereupon by order declare the land forfeit to the State Authority, and the provisions of Part Eight shall have effect with respect thereto accordingly."

But the question is DBKL is not State Authority. So TS u might need to explore a bit more. Huhu.
