Jurisdiction to Modifiy a Judgment
 Property rights created by a judgment of dissolution become vested when the judgment is final, and a trial court lacks general jurisdiction to modify an order affecting these rights. In re Hubbard
 Where modification of decree of dissolution is an agreed order, not contrary to public policy and not shown to have resulted from fraud or coercion, respondent can challenge it on appeal only if the circuit court lacks jurisdiction to enter it. In re Steel
