Consistent with the prior response that was apparently added as a comment but has since been added as a response, your child support needs to be modified. It is only after the last child emancipates that the termination of any support is automatic. The division is not proportional to the number of children but based upon a mathematical formula that offers proportionally less to each child of larger families. Thus, you’ll once your daughter emancipates the child support would be based upon the results of the mathematical formula for child support based upon income, parenting time, and other extraordinary expenses like health insurance premiums and sometimes other regular monthly expenses like work-related day care if you have it.
