As with many life events, divorce is a subject for discussion and debate involving a broad range of disciplines in the humanities and social sciences. Economics is not generally at the forefront of these disciplines; it is lawyers and psychologists who are first in line to accompany conjugal trajectories. Demographers are also widely called upon to examine changes and variations in the phenomenon, providing the necessary basis for formulating possible interpretations of the reasons for these changes, which occur in time, space and, naturally, the social space. Sociologists and economists are part of this second circle of experts interested in the causes and, above all, the consequences of divorce. The article by Cécile Bourreau-Dubois and Myriam Doriat-Duban is unquestionably a useful contribution in this respect. It provides a basis for an actuarial analysis aimed at judging the nature of this " risk " and envisaging the grounds and methods for covering it. The article proposes a model that could probably be converted into a formula at some later stage.
