The Dutch court expects parents who want to divorce to make a parenting plan, in which they write about the way they are going to continue being the parents of the children, together. It contains details on the access arrangements, how to make medical decisions, how to choose a school, etcetera.
If there is no parenting plan, the court might decide to send the parties to parental mediation, where they have meetings about the future of the children. Hopefully, this will enable them to agree on most details.
If there is an understandable reason for not having a parenting plan, for instance if no communication is possible, the court will accept the absence of a parenting plan and make those decisions for the parents.
