Changed economic conditions have modified the situation of Institutes of Consecrated Life and Societies of Apostolic Life as well as the way in which they consider the administration of goods at the service of charism and mission. In the light of the Guidelines given by the Congregation for the Institutes of Consecrated Life for the administration of temporal goods in 2018, the contribution outlines the relationship between universal law and proper law in the administration of goods.  Particular emphasis is placed on the increasingly relevant role of proper law, which must provide normative instruments for a correct and effective management and administration of the ecclesiastical goods of Institutes and Societies. The Author considers the general references to the proper law provided by the Guidelines and in particular the determination of the fixed assets in the proper law and the close relationship between the General Chapter as well as the elaboration of a proper law in economic-administrative matters. Taking for granted that the economic-financial world of our time has also changed the world of religious life, it is necessary
to revise the criteria and the economic-administrative practices of Institutes and Societies, to rethink the administration of goods within the charism, and to facilitate training on financial administration, on communication and collaboration between Institutes in of constructing responsible solidarity.
