Definition
A body of persons united by a common tie — whether of trade, profession, religion, or social interest — and organized for mutual benefit or shared purpose. In legal usage, fraternity has carried two distinct meanings at different points in history:
1. VOLUNTARY ASSOCIATION: A group of individuals organized around a common business, occupation, or social interest, without the formal legal character of a corporation. The members govern themselves by internal rules binding on members only — not on strangers or the general public. This is the dominant sense in historical legal sources and retains practical relevance for questions of associational liability and governance.
2. ESTATE-TAIL (HISTORICAL): In the older English property law of estates, "fraternity" (or "frankmarriage in fraternity") described a specific condition attached to an estate-tail where the donee had married one of kin — a daughter or cousin — to the donor. The estate was held subject to an implied condition that it descend to the issue of that marriage. As with other estates-tail before the statute De donis Conditionalibus, the birth of issue was treated as performance of the condition, after which the estate became alienable by the donee. This sense is now archaic and appears only in historical property law materials.

Common Language
Modern common usage (Wiktionary): The quality of being brotherly; a group of people associated for a common purpose; specifically, a social organization of male students at a college or university, usually identified by Greek letters.
Historical common usage (Webster's 1913): The state or quality of being fraternal or brotherly; a body of men associated for common interest, business, or pleasure; a company or brotherhood; also used to mean men of the same class, profession, or occupation.
The legal meaning is narrower and more consequential than the ordinary one. In common usage, "fraternity" casually describes any brotherhood or student organization. In legal usage — particularly historical legal usage — the term carried structural significance: a fraternity was specifically distinguished from a corporation by its inability to bind non-members through its rules and ordinances. That distinction determined the scope of legal authority and liability. Researchers encountering "fraternity" in older legal materials should not assume the modern collegiate sense.

Common Confusion
FRATERNITY vs. CORPORATION: The critical historical distinction, preserved in Cuddon v. Eastwick (1 Salk. 192), is that a corporation invests a local body with governing authority whose rules bind strangers, while a fraternity is a private association whose ordinances bind only its own members. A corporation derives its authority from the state and can regulate outsiders within its sphere; a fraternity cannot. Researchers who treat these terms as interchangeable in pre-19th-century sources will misread the scope of legal power being described.
FRATERNITY (ASSOCIATION SENSE) vs. FRATERNITY (PROPERTY SENSE): The two legal meanings of the term share nothing beyond the word itself. The property law sense — relating to estates-tail and conditions of consanguinity — is entirely unrelated to associational law. Bouvier's entry conflates both under one headword without clear separation, which creates ambiguity in research.

Why It Matters in Research
The term is a navigational trap in historical sources. A researcher moving through 17th- or 18th-century English legal materials will encounter "fraternity" used with precision in the corporation/association distinction, while a researcher in medieval or early modern property law will encounter it in the estate-tail context. Bouvier's Law Dictionary introduces both senses without adequately signaling the shift, and Anderson's Dictionary of Law deflects entirely to cross-references without definition. Neither is adequate as a standalone research guide.
For associational law research, the fraternity/corporation distinction matters when analyzing the legal capacity of trade guilds, craft associations, religious confraternities, and voluntary organizations to enforce internal rules or incur collective liability. This distinction evolved as corporation law developed through the 18th and 19th centuries; the fraternity category became less legally distinctive as voluntary association law matured.
For property law research, the estate-tail sense requires awareness that the term signals a now-obsolete tenure condition. It will appear in older conveyancing materials and abridgments of real property law but has no modern application in jurisdictions that have abolished fee tail.
Modern contexts — student organizations, professional fraternities, Greek-letter organizations — are governed primarily by contract law, nonprofit corporation statutes, and institutional regulations, not by any specialized legal definition of "fraternity." Courts addressing hazing liability, membership discrimination, or organizational governance generally analyze these entities as unincorporated associations or nonprofit corporations, not as "fraternities" in the historical legal sense.

Historical Dictionary Support
Black's Law Dictionary (both editions) preserves the Cuddon v. Eastwick formulation and treats the corporation/fraternity distinction as the primary legal content of the term. This is the most useful definition for legal historians and for researchers working with early common law materials on associational capacity. The quote is specific and instructive: the key operative difference is whether the body's rules bind strangers.
Bouvier's Law Dictionary is the most problematic source here. Its entry conflates two entirely different legal meanings — the estate-tail property sense and the general associational sense — in adjacent passages without adequate separation or cross-referencing. Researchers relying on Bouvier alone risk conflating doctrines that have nothing to do with each other.
Anderson's Dictionary of Law offers no independent definition, directing readers only to "Association" and "Community." This is unhelpful for a term with distinct legal content, though it reflects Anderson's general approach of consolidating related doctrine under broader headings.
All historical sources share a gap: none addresses the modern institutional fraternity (collegiate or professional) as a legal entity, because that context postdates or was outside the scope of their compilation. The organizational and liability questions most relevant to contemporary researchers are simply not addressed.

Jurisdictional Note
The corporation/fraternity distinction in historical English law has no direct modern American statutory parallel — American law absorbed both forms into the broader categories of corporations and unincorporated associations. Questions about modern fraternal organizations in the United States are typically resolved under state nonprofit corporation acts or unincorporated association statutes, which vary by state.
