In deciding motions under rule 1.1003 or 1.1004, the court shall treat issues not embraced in the pleadings but actually tried by express or implied consent of the parties as though they had been pleaded. Either party may then amend to conform the party's pleadings to such issues and the evidence upon them; but failure so to amend shall not affect the result of the trial.

Full Text of Rule 1.1009
Plain-English Summary
Trials do not always track the pleadings exactly. Sometimes both sides put on evidence and argument about an issue that was never formally raised in the petition or answer, and neither side objects. Rule 1.1009 addresses what the court should do with that gap when it later rules on a motion under rule 1.1003 or rule 1.1004: treat the issue as though it had been pleaded all along, so long as it was tried by the express or implied consent of the parties.
The rule also gives either party the option to amend the pleadings to formally conform them to the issues and evidence that came in at trial. But that amendment is not required to preserve the point. The rule says plainly that failure to amend does not affect the result of the trial — the court still treats the issue as tried, whether or not the paperwork ever catches up.
Frequently Asked Questions
If an issue was never in the pleadings but both sides tried it at trial without objection, can the court still rule on it?
Yes. Rule 1.1009 requires the court, when deciding a motion under rule 1.1003 or 1.1004, to treat an issue tried by the parties' express or implied consent as if it had been pleaded.
Do I need to amend my pleadings to match what was tried at trial?
You are allowed to, but you don't have to. Rule 1.1009 lets either party amend to conform the pleadings to the issues and evidence, but it also states that failing to amend does not affect the result of the trial.
What counts as trying an issue by “implied consent”?
Rule 1.1009 does not define the term further; it directs the court to treat issues tried by implied consent the same as those tried by express consent, and the same as if they had been raised in the pleadings from the start.
Does this rule apply to any post-trial motion, or only specific ones?
It applies specifically to the court's decisions on motions under rule 1.1003 (judgment notwithstanding the verdict) and rule 1.1004 (new trial).
Can the other side object at trial to keep an unpleaded issue out, even if evidence on it comes in anyway?
Rule 1.1009 turns on whether the issue was tried by consent. If a party objects rather than acquiescing, that undercuts a claim that the issue was tried by implied consent, though the rule itself addresses only the consequence once consent is found.
