Case Auction is a bidding system of which clients find out lawyers to handle his/her case through the auction. It is a new lawyer appointment method centered on the legal consumers in which the most suitable lawyers can be appointed. If clients use this Case Auction system, clients, not lawyers decide the fee and lawyers to accept an appointment under the condition them offered. Case auction makes you appoint 'a desired lawyer' at 'a desirable cost'. Until now about 500 cases have put up at auction and in most of them clients have saved their fee up to 20~50%, compared to normal lawyer referral system.
