Can a parent be stopped from seeing their children if they do not pay child support?

No. The right to child support and the right to parenting time are separate legal issues. They are both rights of the child.

A parent cannot be denied parenting time with their child because they have not paid child support. And a parent might still have to pay child support even if they do not have parenting time. For more information, see CLEO's publication Separation and Divorce: Making Decisions and Spending Time with Children.
