Definition
The legal name by which a corporation is formally identified, under which it may sue and be sued, enter into contracts, hold property, and conduct all other legal acts. A corporation acquires its name either expressly, through its charter, articles of incorporation, or equivalent organizing instrument, or by implication when no name is formally assigned. The corporate name is a defining attribute of legal personality: it is the mechanism by which the corporation acts as a juridical entity distinct from its members, officers, and shareholders.
The corporate name is not merely a label of convenience. It is the anchor of the entity's legal capacity. A corporation that fails to act under its proper name risks having acts attributed to it improperly or, in older practice, challenged as ultra vires or void. At the same time, courts have consistently held that minor or immaterial variations in the name — a dropped article, a slight spelling difference — do not invalidate legal proceedings, so long as the identity of the entity is clear.
The corporate name may be changed by competent authority (typically the state of incorporation, through formal amendment of the organizing documents) without affecting the corporation's continuity, obligations, or capacity. The entity remains the same; only the name changes.

Common Confusion
CORPORATE NAME vs. TRADE NAME / FICTITIOUS NAME (DBA): A corporation's legal name is its registered identity for all juridical purposes. A trade name or "doing business as" (DBA) designation is a secondary commercial label that does not replace the legal name for purposes of suit, contract, or liability. Many researchers conflate the two. A corporation sued under its DBA rather than its corporate name may raise the misnomer as a procedural issue, though courts often correct immaterial name errors. The distinction matters acutely when tracing historical litigation records or corporate filings.
CORPORATE NAME vs. TRADEMARK: A corporate name identifies the legal entity; a trademark identifies the source of goods or services. A corporation's name may function as a trademark, or it may not. They are protected through different legal regimes (state corporate registration vs. federal or common-law trademark law), and ownership of one does not automatically confer rights in the other.

Why It Matters in Research
The corporate name is a critical anchor for document tracing in any Law Mind corpus search. Several research traps are common:
Name changes over time create discontinuities in the record. A corporation may have litigated under one name in 1910, changed its name in 1925, and appeared in statutes or secondary sources under both. Historical dictionary sources treat the name as a static identifier; they say nothing about managing the documentary trail across changes. Researchers using historical case reporters or legislative records must account for prior names and variant spellings.
Immaterial variation doctrine generates noise in search results. Because courts historically tolerated minor name deviations, historical sources often record corporation names inconsistently — with or without "Inc.," "Corp.," "Co.," "The," or "&" vs. "and." A search for a corporate name in case law databases must anticipate these variants.
State-level registration records are the authoritative source for a corporation's legal name at any given time, but those records were not always digitized, standardized, or cross-referenced with federal materials. When researching a corporation's capacity to act in a historical transaction, the operative question is the name as it appeared on the organizing documents at the time, not the name as it appeared in contemporaneous journalism or secondary commentary.
The modern intersection of corporate name and domain name creates a research bridge between corporate law materials and intellectual property materials. The ACPA and UDRP proceedings often turn on whether a domain name corresponds to a corporate name, trade name, or trademark — categories that historical sources treated as wholly separate. Researchers working on cybersquatting matters should not assume that a corporate name automatically carries the same legal weight as a trademark in that context.

Historical Dictionary Support
Black's Law Dictionary and Rapalje & Lawrence reproduce nearly identical language on this term, suggesting a shared common-law source (almost certainly drawn from Blackstone or early treatise authority). Both sources establish the same three core propositions: (1) a name attaches to a corporation at formation, expressly or by implication; (2) the corporation acts legally only through that name; and (3) immaterial variations do not affect legal efficacy, and authorized changes do not affect identity or capacity.
The historical entries are serviceable but narrow. They speak to a world of corporate formation by charter or special legislative act, where the name was typically fixed by the granting authority. They do not address the modern regime of general incorporation statutes, which impose affirmative requirements on corporate names — distinctiveness from existing registrations, prohibition on deceptively similar names, mandatory use of corporate designators ("Inc.," "Corp.," "LLC") — none of which existed in the form the historical dictionaries contemplated.
What historical sources miss entirely: the relationship between corporate name and brand identity, the regulatory role of the Secretary of State as a name clearinghouse, name reservation procedures, and the interaction between corporate name registration and trademark law. These are products of twentieth-century administrative and intellectual property development, and researchers should not expect to find them in Black's or Rapalje & Lawrence.

Jurisdictional Note
Corporate name requirements are governed by the law of the state of incorporation. Most states follow the Model Business Corporation Act framework, which requires that a corporate name be distinguishable from names already on file with the state's corporate registry, and that it include a designated corporate identifier. Foreign corporations operating in other states must typically register their name in each state, sometimes under an assumed or alternate name if the original is already taken.
