If u sells it without NOC from the mortgager then the mortgager can sue you for his amount, and the purchaser will not get clear and marketable title. He may loose the propoerty in future if the mortgager sues you for payment of money or cancelletion of said sale deed.

The purchaser of the mortgaged property can hold good title subject to payment of dues to the mortgager.
