Amendment History
(1967, c. 954, s. 1; 1969, c. 895, s. 7.)
Plain-English Summary
Rule 18(a) gives a party asserting a claim — whether an original claim, a counterclaim, a crossclaim, or a third-party claim — room to join as many claims against an opposing party as it has, legal or equitable, independent or in the alternative. The rule does not change what relief a party is entitled to; it only removes the procedural obstacle that would otherwise force separate lawsuits for separate claims against the same opponent.
Rule 18(b) addresses a narrower situation: claims that historically could only be brought after another claim had already been won. Those two claims may now be joined in one action, though the court still grants relief according to each party’s actual substantive rights. The rule gives one specific example — a plaintiff may combine a claim for money with a claim to set aside a conveyance as fraudulent, without first having to obtain a judgment establishing the money claim.
Frequently Asked Questions
How many claims can a party bring against an opponent in one lawsuit?
As many as it has, legal or equitable, whether pleaded independently or in the alternative — Rule 18(a) places no cap on the number of claims joined against the same opposing party.
Does Rule 18 create new rights or remedies?
No. It only lets existing claims be joined procedurally; relief is still granted according to the parties’ actual substantive rights.
Can a plaintiff sue to undo a fraudulent transfer before winning a money judgment?
Yes. Rule 18(b) lets a plaintiff join a claim for money with a claim to set aside a fraudulent conveyance without first obtaining a judgment on the money claim.
