(a) In general. A party asserting a claim, counterclaim, cross-claim, or third-party claim, may join, as independent or alternative claims, as many claims, legal or equitable, as the party has against an opposing party.
(b) Joinder of Contingent claims. A party may join two claims even though one of
them is contingent on the disposition of the other; but the court may grant relief only in accordance with the parties’ relative substantive rights. In particular, a plaintiff may state a claim for money and a claim to set aside a conveyance that is fraudulent as to that plaintiff, without first obtaining a judgment for the money.
