Shared physical custody (SPC) is a care arrangement following parental separation, whereby children alternatively reside with their mother and father. Very little is known about how family policies accommodate SPC, which is all the more unfortunate, as it represents a key opportunity to understand how family policies can efficiently facilitate shared parenting. To address this gap, this article presents a modest attempt at designing a new comparative family policy approach that considers SPC arrangements, by examining the extent to which Belgian, French and Italian family policies accommodate a more equal sharing of parenting post-divorce. In so doing, we encourage studies of defamilialization to take better account of the diversity of contemporary family forms. The theoretical section traces back key feminist debates around defamilialization and proposes to consider SPC arrangements as an ‘atypical’ family configuration that best illustrates contemporary tensions around defamilialization and gender equality. It also takes stock of the few studies of family policy and SPC to highlight key issues at stake. The analysis section starts with the main characteristics of the family law, welfare regime and family policies of the three countries. Then, we examine a selection of emblematic and national-level family policies from the following areas: (1) Family benefits; (2) Financial support to access to services; and (3) Tax measures. Our comparison focuses on three main criteria: scope; entitlement; and shareability of benefits between parents in the context of SPC. Our analysis reveals the variety of approaches to SPC in family polices across countries and policy areas, and the significant lack of support for a more equitable distribution of parenting within SPC. We conclude by highlighting the usefulness of taking SPC into account in reflecting on and evaluating the implementation of defamilialization policies, and by identifying some of the challenges to be met by future research.
