Plain-English Summary
Rule 14 covers third-party practice, sometimes called impleader. If a defendant thinks someone who isn’t already in the case should end up paying part or all of a judgment against it — an insurer, a subcontractor, a co-obligor — this rule lets the defendant bring that person or company in as a third-party defendant. Filing within 14 days of the original answer requires no permission; after that, the defendant needs the court’s leave. Once served, the third-party defendant can raise its own defenses, counterclaims, and crossclaims, and can even fight the plaintiff’s underlying claim using any defense the original defendant has.
The rule also lets the plaintiff use the same tool if a counterclaim turns the plaintiff into a defending party, and it lets a third-party defendant chain the process further by impleading someone who owes it money in turn. Courts keep control over how far this can stretch: any party can move to strike, sever, or separately try a third-party claim that would complicate or delay the main case.
Frequently Asked Questions
What does Rule 14 let a defendant do?
It lets a defendant bring a new party into the case — called a third-party defendant — by claiming that party owes reimbursement or contribution for some or all of what the defendant might owe the plaintiff.
Is there a deadline for filing a third-party complaint without asking the court first?
Yes. A defendant can file it as of right within 14 days after serving its original answer. After that, it needs the court’s permission.
Can the third-party defendant fight the original plaintiff’s claim too?
Yes. The third-party defendant may raise any defense the original defendant has against the plaintiff, and may bring its own claim against the plaintiff if it arises from the same transaction or occurrence.
Can a third-party defendant bring in someone else?
Yes. A third-party defendant can implead a nonparty who may owe it reimbursement, continuing the same chain of liability the rule sets up.
Can a plaintiff use Rule 14 to bring in a new party?
Yes, if a claim is asserted against the plaintiff — for example, through a counterclaim — the plaintiff may implead a third party under the same rules that apply to a defendant.
