Definition
A nominal plaintiff is a party named in a lawsuit who holds no real, beneficial interest in the outcome of the litigation. The nominal plaintiff appears on the pleadings as plaintiff in form only — typically because procedural rules or the law of assignment require the suit to be brought in that party's name, even though the actual economic stake belongs to someone else. The party who holds the true interest is variously called the real party in interest, the use plaintiff, or the beneficial plaintiff.
The classic scenario: a party holds a legal claim and assigns it to another. Under older common-law pleading rules, an assignee of a chose in action could not sue directly in their own name. The assignor — who no longer had any personal stake in the recovery — was nonetheless required to appear as plaintiff. The assignee prosecuted the action for their own benefit under the form "A, for the use of B," where A is the nominal plaintiff and B is the use plaintiff.
Common Confusion
NOMINAL PLAINTIFF vs. REAL PARTY IN INTEREST. These terms describe opposite ends of the same relationship. The nominal plaintiff holds the legal title to the claim but no beneficial interest; the real party in interest holds the beneficial interest but may lack standing to sue directly under older procedural frameworks. Modern rules — including Federal Rule of Civil Procedure 17(a), which requires every action to be prosecuted in the name of the real party in interest — have largely collapsed this distinction by permitting or requiring the beneficial owner to sue directly. Researchers encountering "nominal plaintiff" in pre-twentieth-century sources should not assume the term signals fraud or bad faith; it was a routine procedural mechanism.
NOMINAL PLAINTIFF vs. NOMINAL DEFENDANT. Both terms describe a party joined for form rather than substance, but the positions are procedurally distinct. A nominal defendant is joined because their formal legal interest must be present for complete relief, not because they are an adverse party. Do not conflate the two when analyzing case captions in historical records.
Why It Matters in Research
The concept is largely a creature of historical common-law pleading and carries diminishing practical weight under modern procedure. Researchers need this term primarily to interpret pre-code and early code-pleading era documents — cases, treatises, and digests from roughly the seventeenth century through the late nineteenth century.
Several traps await the unwary:
First, the "for the use of" construction in case names is a signal that a nominal plaintiff is present. A caption reading "Smith, for the use of Jones v. Brown" means Smith is nominal; Jones is the real claimant. Digests and reporters sometimes index these cases under Smith, sometimes under Jones, and occasionally under both. Search accordingly.
Second, the abolition of the nominal plaintiff requirement happened at different times in different jurisdictions. Federal courts moved decisively with the adoption of the Federal Rules in 1938. State courts following Field Code reforms made the shift earlier in some jurisdictions, later in others. A case from an 1880 state court may still operate under nominal plaintiff rules even if federal practice had already evolved.
Third, the concept intersects with the law of assignment and subrogation. Insurance subrogation claims were historically prosecuted through a nominal plaintiff structure — the insured remained the named plaintiff while the insurer, as subrogee, was the real party. Some jurisdictions permitted this arrangement long after others had moved to direct-action rules. When researching insurance subrogation history, nominal plaintiff doctrine is directly relevant.
Fourth, the nominal plaintiff had real procedural consequences beyond mere caption formatting. As Bouvier's notes, the nominal plaintiff generally could not discontinue the action or interfere with the assignee's prosecution of the claim — courts policed this actively. This limitation matters when tracing what happened when nominal plaintiffs died, became incapacitated, or sought to settle contrary to the use plaintiff's interests.
Historical Dictionary Support
Black's and Bouvier's agree on the core definition and both trace the concept to the law of assignment: the nominal plaintiff is one who has transferred the cause of action to another but must remain on the pleadings because the assignee cannot sue directly. Black's adds the partnership analog — a party who lends their name to a firm without a real stake — though this usage is peripheral to the primary procedural meaning and should not be confused with it.
Neither historical dictionary adequately addresses the transition to modern procedure or flags that the concept is largely obsolete under real-party-in-interest rules. Bouvier's citation chain (Wheaton, Cranch, Johnson) points to early American federal and state courts working through these rules in the republic's first decades, which is useful context for researchers in that period. Neither source discusses the insurance subrogation application, which became the most practically significant survival of the nominal plaintiff structure into the twentieth century.
Jurisdictional Note
The nominal plaintiff construct is essentially abolished in federal court by FRCP 17(a) and its state equivalents. However, pockets survive in specific procedural contexts — particularly subrogation, trust litigation, and certain statutory actions — where jurisdiction-specific rules may still require or permit a nominal party structure. Always check local rules when the question arises in a live matter.
Encyclopedia Cross-Reference
No single Law Mind Encyclopedia entry addresses nominal plaintiff procedure directly. Researchers tracing the damages side of nominal-plaintiff litigation may consult: Remedies — Nominal Damages (The Law Mind Contracts & Commercial Law Encyclopedia, contracts_83) for the distinct but easily confused concept of nominal damages.
