What are some common misconceptions people have about child support that you’ve noticed?

I think some people think that overtime won’t be included or bonuses won’t be included. Or, that some extra-curricular activities can be added on that can’t be such as sports fees or equipment fees and things like that. You can’t just keep going back and asking for more money. Most people who receive the support are limited by that amount of support unless they can get the other parent to voluntarily contribute to other extra-curricular activities.
