其他摘要：This article is an attempt to carry out a historical and, principally, comparative study,
centered in the notion of “models circulation”, about unjust enrichment. To put this into
practice, we are going to analyze, first, the responsibility resulting from breach of contract, as a
way to, further, better characterize the unjust enrichment in Comparative Law, based specially
in the study of its origin in the English and Roman traditions.
