In an electoral system, a deposit is the sum of money that a candidate for an elected office, such as a seat in a legislature, is required to pay to an electoral authority before they are permitted to stand for election. In the typical case, the deposit collected is repaid to the candidate after the poll if the candidate obtains a specified proportion of the votes cast. The purpose of the deposit is to reduce the prevalence of 'fringe' candidates or parties with no realistic chance of winning a seat. If the candidate does not achieve the refund threshold, the deposit is forfeited.
