In this paper, I show that Kant can maintain a concept of juridical obligations that satisfies the two main and seemingly paradoxical features of his concept of Right, i. e., that it is moral and that it is external. I present two sets of reasons as to why it is appropriate to expect that Kant has a coherent conception of juridical obligations as external and moral at the same time. The first one has to do with the well-known fact that in Kant´s mature philosophy, "moral", "morals", and, I shall propose, "categorical imperative" do not immediately nor necessarily refer to internal, ethical obligations. The second one relates to the thesis I advance here: That reciprocity, as entailed in the definition of "innate equality", is the source of juridical normativity and a solid answer to the question "What makes Kantian Right moral?".
