One of the most obvious consequences of divorce is the moving out of one or both ex‐partners from the formerly common household. Here we focus on a particular postdivorce residential move, the return to the parental home in Sweden, where intergenerational coresidence is uncommon. We ask whether family dissolution increases the likelihood of intergenerational coresidence among separated/divorced individuals who have at least 1 child below age 18. Furthermore, we ask whether the strength of the effect depends on socio‐economic and geographical factors. Our analysis of 670,777 individuals from Swedish population register data shows that even if living with parents is, in absolute terms, not a common intergenerational support strategy, its likelihood increases considerably after a family dissolution. This event increases the probability of living with one's parents especially among men, those with low incomes, and those who live close to their parent(s). We discuss the implications of our findings for the literature on patterns of intergenerational support across Europe.
