This book is the first book to comprehensively and deeply explain and construct the legal system of Chinese art auctions. Based on agency theory in traditional contract law, this book combs the legal relationship between client, auctioneer, and buyer. Aiming at the most difficult problem of art identification, this book shows the obligations that auctioneers must perform and the common methods for auctioneers to avoid these obligations. The purpose of this book is to ease the current situation in which the interests of buyers and auctioneers are too opposed and speed up the legalization process of art auctions through the construction of the legal system of art auctions in China. Additionally, using the method of policy demonstration, this book discusses how public power should intervene in the process of art auctions.
