I'm still trying to get my life and my son's together after my ex broke up with me in June. We're being civil and seem to be getting along better. Anyway, when it comes to child support, are you supposed to factor in rent and utilities? Right now I'm staying with my parents so I'm not paying rent or utilities. I help out with food and my dad watches my son. My ex is going to be paying rent, utilities and daycare when he has our son. If rent and utilities count, I could be paying him CS. Any help or suggestions would be greatly appreciated.
