Social life is fostered by having a partner and children that create interactions and generate new social networks. For divorced parents, the question is whether these positive relationships remain after marital dissolution. Do children form an additional barrier to social interaction, or do new partners present a means to reconstruct divorcees' social life? In this case, it is important to consider custody arrangements. The research question is how custody arrangements affect divorced parents' possibilities to participate in outdoor home leisure activities and to maintain their social contacts. Focus is placed on the recent post-divorce parenting model of joint physical custody, taking Belgium as a pioneer case study. Multi-level regressions are conducted, using multi-actor data from the Divorce in Flanders survey (N = 1506 divorced parents). Results show that joint physical custody helps divorced parents to stay socially integrated. Especially for mothers, joint physical custody has a liberating effect. They engage in more outdoor home activities and better maintain their social networks than sole custody mothers. In this way, the positive effects of social interaction can counterbalance other detrimental effects of divorce and contribute to a higher level of their general well-being. While joint custody for fathers means they may spend more time with their children, their engagement in personal leisure activities and social networks is not altered by this custody arrangement.
