Parenting time, custody and child support are established by filing a complaint for divorce if you are married. In your complaint for divorce when you are married, you can ask for custody, parenting time and child support to be established and ordered by the court. If you are not married you would ask the court to establish paternity, custody, and child support as well as parenting time. And to do that you'd file a petition to establish custody, paternity, child support and parenting time. Once those are filed, that starts the case.
