Objectives. Although the consequences of parental divorce for specific family relationships are increasingly studied, it remains unexplored how parental divorce reverberates through the larger family network, impacting not only the relationships with and between parents and their children, but also with grandparents. This study aims to unravel how three-generational, bi-lateral contact patterns manifest in the larger family network and how they differ when families experienced parental divorce. Methods. 4,436 families from the multi-actor Divorce in Flanders data with 1-5 family members (one child, father, mother, and paternal and maternal grandparents) reporting on contact with 1-7 family members are analyzed using a Social Relations Model. Results. Results show that parents have less frequent contact with their parents-in-law than with their own parents, indicating a clear fault line, which is deeper in divorced families. Mothers – compared to fathers – have more contact with their own parents, but fathers – compared to mothers – do not have more contact with their in-laws. Divorced fathers have more frequent contact with their own parents compared to non-divorced fathers. Less frequent contact with paternal (maternal) grandparents co-exists with more frequent contact with maternal (paternal) grandparents, indicating substitution, which is not stronger in divorced families. Discussion. The network approach enabled uncovering resilient strategies, i.e., substitution, in families experiencing an imbalance in paternal and maternal grandparental contact. The results emphasized the significant role of grandparents following divorce, particularly in the case of fathers, who appear to place greater reliance on maintaining contact with their parents after divorce.
