When the Promotion of Continued Parenting and Proper Divorce Act came into force on March 2009 both married and cohabiting Dutch parents of minor children were obliged to draw up a parenting plan when they separate. Parenting plans are not enforceable for cohabiters, however. Using data from the New Families in the Netherlands survey, we examine how many former cohabiters create a parenting plan and how this compares to the number of verbal or no arrangements. We expect that child, parents and relationship characteristics are important for the likelihood that a parenting plan is constructed. Results show that more than half of former cohabiters create a parenting plan. Furthermore, former cohabiters are more likely to draw up a parenting plan if they consult a legal practitioner during their separation process. In addition, the younger the youngest child is, the more likely that former cohabiters will create a parenting plan or make verbal arrangements rather than no arrangements. That is also true for higher educated households and if they opt for residential co-parenting after divorce. Former cohabiters in a high-conflict situation are less likely to develop a parenting plan than make no arrangements.
