A deposit is considered to be unclaimed if there has been no activity on it for ten years or longer, such as a deposit of funds or a withdrawal from the depositor. Harsh Roongta, Founder, Fee Only Investment Advisers LLP, told ET last month this amount could be as high as Rs 50,000 crore. Early last month, the Supreme Court asked the Ministry of Finance to respond to a PIL seeking a mechanism to inform the legal heirs of deceased depositors about the unclaimed deposits lying dormant in bank accounts.
