A trial court is without authority to modify an agreement providing for child support absent (1) a pleading directed to the subject, (2) an appropriate proceeding conducted after notice, (3) a finding of changed circumstances, and (4) in a case where increased child support payments are sought, a record finding of respondent’s ability to pay.
