In one sentenceRule 1.270 governs counterclaims in class litigation -- letting a defendant counterclaim against a certified plaintiff class or, with leave, against an individual member or subclass, requiring any such counterclaim in a plaintiff-class case to be raised before class notice goes out, and allowing a defendant class itself to counterclaim against the plaintiff.

1.270(1) A defendant in an action brought by a class may plead as a counterclaim any claim the court certifies as a class action against the plaintiff class. On leave of court, the defendant may plead as a counterclaim a claim against a member of the class or a claim the court certifies as a class action against a subclass.
1.270(2) Any counterclaim in an action brought by a plaintiff class must be asserted before notice is given under rule 1.266.
1.270(3) If a judgment for money is recovered against a party on behalf of a class, the court rendering judgment may stay distribution of any award or execution of any portion of a judgment allocated to a member of the class against whom the losing party has pending an action in or out of state for a judgment for money, and continue the stay so long as the losing party in the class action pursues the pending action with reasonable diligence.
1.270(4) A defendant class may plead as a counterclaim any claim on behalf of the class that the court certifies as a class action against the plaintiff. The court may certify as a class action a counterclaim against the plaintiff on behalf of a subclass or permit a counterclaim by a member of the class. The court shall order that notice of the counterclaim by the class, subclass, or member of the class be given to the members of the class as the court directs, in the interest of justice.
1.270(5) A member of a class or subclass asserting a counterclaim shall be treated as a member of a plaintiff class for the purpose of exclusion under rule 1.267.
1.270(6) The court's refusal to allow, or the defendant's failure to plead, a claim as a counterclaim in a class action does not bar the defendant from asserting the claim in a subsequent action.

Plain-English Summary

Counterclaims complicate class litigation because they can pull individual members into disputes they never chose to litigate. Rule 1.270 manages that complexity from both directions. A defendant sued by a plaintiff class can counterclaim against the class itself if the court certifies the counterclaim as a class action, and with the court's leave, can counterclaim against an individual member or against a subclass the court certifies. Any counterclaim in a plaintiff-class action has to be raised before notice of the class goes out under rule 1.266 -- the class members need to know about the counterclaim when they decide whether to stay in the case or opt out.

The rule also lets a defendant class counterclaim against the plaintiff, again with the court certifying the counterclaim as its own class action, or certifying it on behalf of a subclass, or permitting an individual member to bring it -- with notice given to the class as the court directs. A member of a class or subclass who asserts a counterclaim is treated, for opt-out purposes, as a member of a plaintiff class under rule 1.267. And the rule protects a defendant whose counterclaim the court refuses to certify, or who chooses not to plead it in the class action: that defendant is not barred from bringing the same claim later in a separate lawsuit. Rule 1.270(3) adds a practical safeguard, letting the court stay distribution of a money judgment allocated to a class member against whom the losing party has a pending action elsewhere, and continue that stay so long as the losing party pursues its own pending action with reasonable diligence.
