ABSTRACT This paper addresses the impact of COVID-19-induced uncertainty on union formation intentions in Italy. We acknowledge that decisions made in uncertain conditions rely on personal narratives of the future, that is socially-constructed contingent plans for achieving a personal imaginary. The data come from an on-line survey experiment carried out during the final week of lockdown in Italy on a sample of 1,846 individuals in a romantic relationship (cohabiting or living apart together). Our findings suggest that narratives of the future have a causal effect on marriage intentions: expectations of a long wait before the return to pre-pandemic conditions negatively influence marriage intentions. On the other hand, cohabitation seems more compatible with the uncertainties of today's world. The present study gives a prominent role to the future in family formation practices, net of more ‘traditional’ factors that have been considered in the literature on family life courses.
