(a) Jury and Non-Jury Actions. A new trial may be granted to all or any of the parties and on all or a part of the issues. To preserve for appeal a challenge to the failure of the trial court to make required findings of fact, a party must raise that issue in a motion for rehearing under this rule. On a motion for a rehearing of matters heard without a jury, including summary judgments, the court may open the judgment if one has been entered, take additional testimony, and enter a new judgment.
(b) Time for Motion. A motion for new trial or for rehearing must be served not later than 15 days after the return of the verdict in a jury action or the date of filing of the judgment in a non-jury action. A timely motion may be amended to state new grounds in the discretion of the court at any time before the motion is determined.
(c) Time for Serving Affidavits. When a motion for a new trial is based on affidavits, the affidavits must be served with the motion. The opposing party has 10 days after such service within which to serve opposing affidavits, which period may be extended for an additional period not exceeding 20 days either by the court for good cause shown or by the parties by written stipulation. The court may permit reply affidavits.
(d) On Initiative of Court. Not later than 15 days after the date of filing of the judgment or within the time of ruling on a timely motion for a rehearing or a new trial made by a party, the court of its own initiative may order a rehearing or a new trial for any reason for which it might have granted a rehearing or a new trial on motion of a party.
(e) When Motion Is Unnecessary; Non-Jury Action. In a non-jury action, the sufficiency of the evidence to support the judgment may be raised on appeal whether or not the party raising the question has made any objection thereto in the trial court or made a motion for rehearing, for new trial, or to alter or amend the judgment.
(f) Order Granting to Specify Grounds. All orders granting a new trial must state the specific grounds therefor. If such an order is appealed and does not state the specific grounds, the appellate court shall relinquish its jurisdiction to the trial court for entry of an order specifying the grounds for granting the new trial.
(g) Motion to Alter or Amend a Judgment. A motion to alter or amend the judgment shall be served not later than 15 days after the date of filing of the judgment, except that this rule does not affect the remedies in rule 1.540(b).
(h) Motion for Remittitur or Additur.
(1) Not later than 15 days after the return of the verdict in a jury action or the date of filing of the judgment in a non-jury action, any party may serve a motion for remittitur or additur. The motion must state the applicable Florida law under which it is being made, the amount the movant contends the verdict should be, and the specific evidence that supports the amount stated or a statement of the improper elements of damages included in the damages award.
(2) If a remittitur or additur is granted, the court must state the specific statutory criteria relied on.
(3) Any party adversely affected by the order granting remittitur or additur may reject the award and elect a new trial on the issue of damages only by filing a written election within 15 days after the order granting remittitur or additur is filed.
