Appellants, Robert and Audree Ayer, appeal a final judgment in favor of Melvin Bush ordering the Ayers to pay attorney’s fees and convey property. This is actually the fourth time this case has been before this court.1 The prior appeals constitute the law of the case with respect to the substantive issues raised in this appeal as to the liability to convey property and pay attorney’s fees. Dicks v. Jenne, 740 So.2d 576, 577 (Fla. 4th DCA 1999).

After remand from the last appeal, the trial court complied with our directions, but then several months later a successor judge entered an additional final judgment consolidating the various judgments and offsetting the attorney’s fees award against the purchase price.2 Once the *787third amended final judgment was entered in accordance with instructions from this court, it could not be modified further, and the litigants’ rights and obligations became fixed. Jared v. Jackson, 483 So.2d 51, 52 (Fla. 4th DCA 1986). We reverse the judgment consolidating all prior orders and judgments as to fees and costs. Our reversal is without prejudice to the trial court considering the issue of attorney’s fees for the last appeal, pursuant to our order of November 3, 2003.
