Utah R. Civ. P. 18

(a) Joinder of claims. The plaintiff in a 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 either the plaintiff or defendant 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 crossclaims or third-party claims if the requirements of Rules 13 and 14 respectively are satisfied.

(b) Joinder of remedies; voidable transactions. Even if a claim arises only after another claim has been prosecuted to a conclusion, the two claims may be joined in a single action; but the court will 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 voidable transaction without first having obtained a judgment establishing the claim for money.
