Wis. Stat. § 803.02: Joinder of claims and remedies.

(1) A party asserting a claim to relief as an original claim, counterclaim, cross claim, or 3rd-party claim, may join, either as independent or as alternate claims, as many claims, legal or equitable, as the party has against an opposing party.

(2) Whenever a claim is one heretofore cognizable only after another claim has been prosecuted to a conclusion, the 2 claims may be joined in a single action; but the court shall grant relief in that action only in accordance with the relative substantive rights of the parties. In particular, a plaintiff may state a claim for money and a claim to have set aside a conveyance fraudulent as to the plaintiff, without first having obtained a judgment establishing the claim for money.
