NEHA PATEL, APPELLANT,

v.

RASESH PATEL, APPELLEE

BLACK, Judge.

We affirm the order on modification of final judgment of dissolution of marriage, which denies Neha Patel’s motion to modify the final judgment as it relates to time-sharing. Competent substantial evidence supports the trial court’s finding that Ms. Patel met her burden of establishing a substantial, material, and unanticipated change in circumstances since the entry of the final judgment of dissolution of marriage. See Wade v. Hirschman, 903 So.2d 928, 934 (Fla. 2005) (“A decree for purposes of the substantial change test includes both a decree that has incorporated a stipulated agreement concerning child custody and a decree awarding custody after an adversarial hearing.”). And we find no error in the court’s determination that modification was not in the child’s best interests at the time of the evidentia-ry hearing.

However, we remand with directions that the trial court strike the language of paragraph eleven following its finding that it is not in the minor child’s best interests to modify the current timesharing and parental responsibility “at this time.”1 The trial court may neither determine the child’s best interests prospectively, see Eisele v. Eisele, 91 So.3d 873, 874-75 (Fla. 2d DCA 2012), nor delegate its statutory duties to a parent or expert, Grigsby v. Grigsby, 39 So.3d 453, 457 (Fla. 2d DCA 2010). Future motions to modify the final judgment with regard to timesharing are governed by the statutory requirements to establish a “substantial, material, and unanticipated change in circumstances” since entry of the final judgment—which has been met in this case—and that “modification is in the best interests of the child.” See § 61.13(3), Fla. Stat. (2016); see also Howell v. Howell, 207 So.2d 507, 511-12 (Fla. 2d DCA 1968) (discussing the law of the case doctriné).

Affirmed; remanded with instructions.
