Definition
Fictitious, in legal usage, describes something feigned, false, pretended, or based on a legal fiction — a fact or circumstance treated as real for purposes of legal procedure or doctrine even though it is not actually true. The term operates in two distinct but related senses:
1. Procedural or doctrinal fiction: A fact or circumstance that law deliberately treats as true in order to reach a just or workable result, without asserting that it is factually accurate. Legal fictions of this kind are not fraudulent; they are acknowledged devices of legal reasoning.
2. Fraudulent or counterfeit falsity: Something that is false or pretended in a manner intended to deceive — as in a fictitious name, fictitious payee, or fictitious plaintiff — where the fiction is not a recognized legal device but rather an unauthorized misrepresentation.
The distinction matters. A legal system may sanction a fictitious premise to achieve procedural ends (sense 1) while simultaneously treating an unauthorized fictitious representation as grounds for liability or nullity (sense 2).

Common Language
Modern common usage (Wiktionary): Invented; contrived.
Historical common usage (Webster's 1913): Feigned; imaginary; not real; fabulous; counterfeit; false; not genuine.
The common meaning captures part of the legal meaning but collapses a critical distinction. In ordinary speech, "fictitious" simply means not real. In law, something fictitious can be either a sanctioned procedural device (a legal fiction that courts openly employ) or a fraudulent falsehood that taints a transaction. A researcher who reads "fictitious" in an older legal text and assumes pure falsity may miss that the term sometimes describes a court-approved mechanism rather than wrongdoing.

Common Confusion
FICTITIOUS vs. FRAUDULENT: These terms overlap but are not synonymous. A fictitious fact in the legal-fiction sense is openly acknowledged and carries no wrongful intent; courts and legislatures create fictions deliberately. A fraudulent misrepresentation is concealed and intended to deceive. A fictitious name on a negotiable instrument may be fictitious in the second (deceptive) sense, but a fictitious plaintiff in the old common law action of ejectment was fictitious in the first (sanctioned) sense. Context — and the era of the source — determines which sense applies.
FICTITIOUS vs. SIMULATED: In some civil-law jurisdictions and in contract law, a simulated transaction is one where the parties agree that their apparent act does not reflect their true intent. Simulation and fiction overlap conceptually but are technically distinct: a legal fiction is a device of the court or legislature; simulation is a product of party agreement.

Recognized Forms
/SUBTYPES
Fictitious action: An action brought not to resolve a genuine dispute but solely to obtain a court's opinion on a point of law. A collusive or feigned lawsuit constructed around facts the parties have invented. Distinct from a test case or declaratory judgment action, which involves a real controversy.
Fictitious name: A counterfeit, feigned, or assumed name used by a person or business entity, differing from the person's or entity's true name. Relevant in negotiable instruments law (the fictitious payee rule), business registration law (doing-business-as statutes), and criminal law (false identity).
Fictitious payee: In negotiable instruments, a payee named on an instrument who either does not exist or who the drawer does not intend to have any interest in the instrument. The fictitious payee rule allocates loss in forgery scenarios.
Fictitious plaintiff/defendant: A named party who is not a real person or whose identity is used as a procedural device. Historically employed in common law actions such as ejectment, where John Doe and Richard Roe served as standard fictitious parties.

Why It Matters in Research
The word "fictitious" in historical legal sources can point in entirely different directions depending on context, and collapsing those directions produces research errors.
In older equity and common law pleading materials, fictitious parties and fictitious facts are procedural infrastructure — recognized, routine, and uncontroversial. The action of ejectment, for example, was built on a fabric of acknowledged fictions. A researcher encountering "fictitious" in those materials should not read wrongdoing into the term.
In commercial law sources — particularly those dealing with bills of exchange, promissory notes, and negotiable instruments — "fictitious" almost always signals a problem: a fraudulent or nonexistent payee, a forged indorsement, or a bad-faith transaction. The fictitious payee rule is one of the most litigated areas of negotiable instruments law, and tracing its development across different eras requires careful attention to how courts defined "fictitious" and whether they required proof of fraudulent intent.
Researchers using Black's 2nd Edition (c. 1910) should note that the definition is terse and the examples limited. Later editions and specialized commercial law dictionaries substantially develop the fictitious payee doctrine. The absence of that development in early editions is not an indication that the doctrine did not exist — it was already generating significant case law — but simply that Black's early editions did not attempt comprehensive doctrinal coverage.
Jurisdictional variation in fictitious name statutes is substantial. Many states require businesses operating under a fictitious name (a trade name or DBA) to file registration documents; failure to register may affect the business's ability to sue in its own name. These statutes vary widely and have changed frequently. Researchers tracing corporate or partnership disputes should check the applicable registration statute as of the date of the relevant transaction.

Historical Dictionary Support
Black's 2nd Edition defines fictitious as "founded on a fiction; having the character of a fiction; false, feigned, or pretended" and provides two specific sub-entries: fictitious action and fictitious name. The definition is serviceable but does not resolve the fundamental tension between the sanctioned-fiction sense and the fraudulent-falsity sense — it lists both without distinguishing them, which reflects the period's acceptance of legal fictions as ordinary instruments of pleading rather than anomalies requiring explanation.
The definition of fictitious action — "brought for the sole purpose of obtaining the opinion of the court on a point of law, not for the settlement of any actual controversy" — is narrower than what later law would call a collusive suit, and distinct from a declaratory judgment proceeding, which had not yet been codified in most American jurisdictions at the time of Black's 2nd Edition. Researchers should not read backward from modern declaratory judgment doctrine when interpreting this entry.
No major historical legal dictionary provides a comprehensive treatment of the fictitious payee doctrine in the commercial law sense. That doctrine developed primarily through case law and is better traced through annotated editions of the Uniform Negotiable Instruments Law and, later, the Uniform Commercial Code, than through general legal dictionaries.

Jurisdictional Note
Fictitious name (DBA) registration requirements vary significantly by state in both their scope and their consequences for noncompliance. In some jurisdictions, failure to register a fictitious business name bars the unregistered entity from maintaining a lawsuit under that name until registration is completed; in others, noncompliance carries only a fine. The fictitious payee rule, codified in UCC Article 3, is more uniform across states but has generated divergent judicial interpretation on questions of employer liability for employee fraud.
