The paper deals with the relationship between comparative law and the law of unjust or unjustified enrichment. More specifically, it enquires whether the discipline of comparative law can learn any lessons from recent experiences with the use of comparative perspectives in enrichment law. The first part of the paper focuses on experiences with the identification and description of foreign law, and inter alia concerns the use of the functional approach. In the second part of the paper the focus shifts to experiences with evaluating competing approaches to enrichment liability. Particular attention will be paid to the criteria which enrichment lawyers use when evaluating the merits of these approaches.
