Does a non-custodial parent (Michigan) have to pay for the following:?

Once child support is established and defined, the parents can only negotiate items not covered. Unless it was listed as an item to share costs on and how those costs would be shared, you can only request the other parent share the cost. Co parenting is hell. You always hope the other parent will help but often it becomes a battle. Not sure if it is worth going to court to redefine child support and shared costs for expenses. But that is the only way to force the issue.
