SOUD, J.

Appellant Jennifer Martin appeals the trial court’s denial of her verified motion to set aside marital settlement agreement, which she filed after entry of the final judgment ratifying the agreement, making it a part of the judgment, and dissolving her marriage to Appellee Craig Sater. We have jurisdiction. See Art. V, § 4(b)(1), Fla. Const.; Fla. R. App. P. 9.030(b)(1)(A). We affirm because Martin failed to establish a legally sufficient basis to set aside the final judgment of dissolution of marriage under Florida Family Law Rule of Procedure 12.540. In reaching this decision, we recede from Suppa v. Suppa, 871 So. 2d 988 (Fla. 5th DCA 2004), which declined to apply Rule 12.540 under similar circumstances.

I.

Martin and Sater separated after a more than 28-year marriage. During their marriage, Sater was a dentist, and Martin worked in the dental practice. Contemplating the immediate filing of a petition for dissolution of their marriage, the parties voluntarily attended numerous mediation sessions with a certified family law mediator who was an attorney and had been contacted by Martin to conduct the mediation. The result was a marital settlement agreement. 1

Pertinent here, the parties agreed to the distribution of considerable marital assets, alimony, and other necessary considerations involved with dissolving the marriage. Regarding equitable distribution, the agreement included a detailed list and valuation of assets identifying the dental practice (and a related company), numerous properties, automobiles, and financial accounts the parties owned.

Just two days after the parties signed the agreement, Martin petitioned to dissolve the marriage. The trial court entered its uncontested final judgment of dissolution of marriage that ratified the marital settlement agreement and made it a part of the judgment.

Nearly nine months later, Martin filed her verified motion to set aside the marital settlement agreement, relying on Casto v. Casto, 508 So. 2d 330 (Fla. 1987). Martin claimed that during mediation of the parties’ divorce, she remained “an emotional

2 wreck” because her father died in June 2019, and she had to put down her dog. She also alleged Sater, who was “in full control of the finances,” never provided financial disclosures and “provided misinformation” by telling her that the agreement “was the best she was going to get in Court and that she better sign or she was going to get nothing. If we go to Court, I guarantee you, I will get more than you.” As a result of her state of mind, lack of financial disclosure, and the alleged misinformation from Sater, she asserted the agreement should be set aside as it was “patently unfair on its face and would shock the conscious [sic].”

Relying on Casto, the trial court denied the motion. Specifically, the trial judge found insufficient evidence that Sater engaged in “fraud, deceit, duress, coercion, misrepresentation, or overreaching” and that Martin “had a general knowledge and understanding of the Husband’s business and its generated income” and she failed to show the agreement was unfair to her in its terms.

This appeal followed.

II.

In resolving this case, we first consider which law governs Martin’s motion. Should the motion have been resolved under the dictates of Casto, or does Florida Family Law Rule of Procedure 12.540 drive the trial court’s analysis? And we do so de novo. See O’Hair v. O’Hair, 396 So. 3d 630, 631 (Fla. 6th DCA 2024) (citing Bosem v. Musa Holdings, Inc., 46 So. 3d 42, 44 (Fla. 2010)), review denied, No. SC2024-0853, 2024 WL 3515473 (Fla. July 24, 2024). Though the trial court’s Casto analysis was consistent with our binding precedent in Suppa, we now conclude Casto does not apply. Rather, rule 12.540 governs.

A.

1.

At the outset, it is helpful to recall Casto and certain of its progeny. In Casto, the parties entered into a postnuptial agreement approximately one year prior to filing a dissolution action—when the parties were not contemplating divorce. See

3 Casto, 508 So. 2d at 332. After the husband filed his petition for dissolution of marriage, and before entry of final judgment, the wife successfully moved to set aside the postnuptial agreement. See id. Ultimately, the Florida Supreme Court held that a postnuptial agreement may be set aside if the challenging spouse establishes: (a) that the agreement “was reached under fraud, deceit, duress, coercion, misrepresentation, or overreaching”; or (b) “that the agreement makes an unfair or unreasonable provision for that spouse,” and the defending spouse is not able to show either (i) full and frank disclosure regarding the assets and income of the parties or (ii) “a general and approximate knowledge [of the] challenging spouse” as to the character and extent of the marital property. See id. at 333.

Years later, the Florida Supreme Court addressed the applicability of the Casto analysis to a post-judgment challenge of a marital settlement agreement reached by counseled parties after the dissolution action was filed and the parties conducted discovery. See Macar v. Macar, 803 So. 2d 707, 711–13 (Fla. 2001). In this context, the Florida Supreme Court held,

[R]ule 1.540, and not Casto, provides the framework for challenging settlement agreements entered into after the commencement of litigation and utilization of discovery procedures. . . . Casto applies only to agreements entered into prior to litigation and discovery, because before spouses file for dissolution, they engage each other as fiduciaries and as such, fraudulent behavior may be perpetrated more easily.

Id. at 713. 2

Thereafter, we held in Suppa that the Casto analysis applied to a post-judgment challenge to a marital settlement agreement reached by parties (with the assistance of a paralegal) in

2 At the time of Macar, rule 12.540 provided that Florida Rule

of Civil Procedure 1.540 applied except that there was no time limit on claims of fraudulent financial affidavits in marital or paternity cases. See 803 So. 2d at 709 n.4; see also Suppa, 871 So. 2d at 989 n.1.

4 contemplation of an imminent petition for dissolution action, which was filed shortly thereafter. See 871 So. 2d at 988–90. Following a hearing on the petition, the trial court entered its “Final Judgment of Dissolution of Marriage with Marital Settlement Agreement.” See id. at 988. Less than one month later the former wife moved to set aside the judgment, alleging fraud and misrepresentations by the former husband and her lack of adequate knowledge of her rights and financial resources of the marriage. See id. at 988–89. Relying on Casto, the trial court granted the motion and set aside the agreement. See id. at 989–90. We affirmed, stating, “[t]his case is controlled by Casto.” Id. at 990.
