In this proceeding for an upward modification of the child support provided by a final judgment of dissolution, the trial court ordered the father to file a financial affidavit notwithstanding that he stipulated to his ability to satisfy any increase in the child’s needs sought by the mother, if awarded by the court. This order plainly represents a departure from the essential requirements of the law as established in, among many other cases, Bravemnan v. Braverman, 549 So.2d 750 (Fla. 3d DCA 1989), and Young v. Young, 456 So.2d 1282 (Fla. 3d DCA 1984). Contrary to the trial judge’s view, the subsequent enactment of section 61.30(12), Florida Statutes (1989),1 does not change the result. If arguendo the provision conflicts with Fla.R.Civ.P. 1.611(a),2 as interpreted in these cases, it represents an invalid legislative intrusion into the procedural rule making authority of the supreme court. Haven Fed. Sav. & *807Loan Ass’n v. Kirian, 579 So.2d 730 (Fla.1991); Cozine v. Tullo, 394 So.2d 115 (Fla.1981); Markert v. Johnston, 367 So.2d 1003 (Fla.1978). Accordingly, the order under review is quashed.
Certiorari granted.
