This case points out the 3-step procedure for arriving at New Jersey child-support obligations, when the parties have equal parenting time. This takes into account that both parents, not just the parent who receives the support, pay certain "controlled expenses," such as clothing, entertainment and personal-care expenditures, above and beyond "fixed" and "variable" costs.
