This is a study about legal convergence in European consumer sales law. It aims to offer a comparative and numerical analysis on the extent to which European directives in this field contribute to convergence. It does so by developing a comparative and numerical framework to evaluate the ambit of such convergence, as well as the factors on which it is dependent. This analysis aims to fill a clear gap in the existing literature on European harmonisation that, until now, has avoided assessing the actual converging effect of European Union (EU) legislation.
