Full Text of Rule 18
Amendment History
This rule’s current text took effect January 1, 1970. For the full history of earlier amendments and adoption orders, see the Indiana Office of Court Services.
Plain-English Summary
Section A gives Indiana litigants a broad joinder right. Anyone asserting a claim — whether as an original claim, a counterclaim, a cross-claim, or a third-party claim — can combine as many claims against a single opposing party as they have, regardless of whether those claims sound in law, in equity, or under a statute. The claims can be joined as independent demands, each standing on its own, or as alternatives, where a party is saying, in effect: give me relief under this theory, or if that doesn’t work, under this one instead. Nothing in the rule requires the claims to be related to each other or to arise from the same events — the only requirement is that they run against the same opposing party.
Section B addresses a narrower, older problem: some claims used to be off-limits until a party had already won a separate, earlier lawsuit. The rule does away with that sequencing requirement — a claim that once had to wait for a prior judgment can now be joined with the claim it depended on, in the same action. The rule gives one concrete example: a plaintiff can combine a claim for money owed with a claim to set aside a conveyance made to defraud them, without first having to win a judgment on the money claim and only then suing to unwind the fraudulent transfer. That said, joining the claims procedurally doesn’t change the underlying law — the court still has to award relief consistent with each party’s actual substantive rights, which may still mean resolving the claims in a particular order even though they were filed together.
Frequently Asked Questions
Can I bring several unrelated claims against the same defendant in one lawsuit?
Yes. Trial Rule 18(A) lets a party join as many claims as they have against an opposing party, whether the claims are legal, equitable, or statutory, and without requiring that the claims be related to each other.
Am I required to bring all my claims against someone in a single lawsuit, or can I sue on the rest later?
Joinder under Trial Rule 18 is a right, not an obligation — the rule lets a party combine claims but doesn’t force it. Other rules can create a separate obligation to raise a particular claim in the current case, most notably the rule on compulsory counterclaims, so it’s worth checking whether a specific claim falls into that category before deciding to hold it back.
Can I plead alternative or inconsistent claims against the same party?
Yes. Trial Rule 18(A) allows claims to be joined either as independent claims, each standing on its own, or as alternative claims, where a party asks for relief under one theory or, failing that, under another.
What does Trial Rule 18(B) mean by claims that were once “cognizable only after another claim has been prosecuted to a conclusion”?
It refers to claims that, before this rule, could only be brought after a party had already won a separate, earlier lawsuit. Trial Rule 18(B) lets those claims be joined with the claim they depend on in a single action instead of requiring two lawsuits filed one after another.
Can I sue to set aside a fraudulent conveyance before I’ve won a judgment on the underlying debt?
Yes. Trial Rule 18(B) specifically allows a plaintiff to combine a claim for money with a claim to set aside a conveyance that defrauded them, without first obtaining a judgment on the money claim.
If I join several claims under Trial Rule 18, will they all be tried together?
Not necessarily. Trial Rule 18 lets you join the claims in one lawsuit, but a court can still order separate trials on particular claims or issues when that would serve convenience, avoid prejudice, or promote efficiency.
