Rule 18. Joinder of claims and remedies.
(a) Joinder of claims. The plaintiff in his complaint or in a reply setting forth a counterclaim and the defendant in an answer setting forth a counterclaim may join either as independent or as alternate claims as many claims either legal or equitable or both as he may have against an opposing party. There may be a like joinder of claims when there are multiple parties if the requirements of Rules 19, 20, and 22 are satisfied. There may be a like joinder of cross-claims or third-party claims if the requirements of Rules 13 and 14 respectively are satisfied.
(b) Joinder of remedies; fraudulent conveyances. Whenever a claim is one heretofore cognizable only after another claim has been prosecuted to a conclusion, the two 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 him, without first having obtained a judgment establishing the claim for money.
