Definition
Persons who have joined together under a partnership agreement to carry on a business for profit, sharing ownership, management authority, and liability according to the terms of their agreement and applicable law. The term encompasses all members of a partnership firm, whether or not their names appear publicly, and whether or not their liability is limited.
In business law, partners collectively constitute the partnership entity. Each partner is simultaneously a co-owner of partnership property, an agent of the firm with authority to bind the other partners, and a debtor jointly and severally liable for firm obligations (subject to variations in limited and limited liability partnerships).
In family and domestic relations law, "partners" is also used to describe persons in committed intimate relationships who are not legally married — including domestic partners and civil union partners — for purposes of property rights, support obligations, and parentage.

Common Language
Modern common usage (Wiktionary): Plural of partner. Persons who share something together — a project, a relationship, a business venture — without implying any formal legal arrangement.
Historical common usage (Webster's 1913): Associates or participants sharing in something jointly; one who partakes with another.
The gap between ordinary and legal meaning is significant. In everyday speech, "partners" carries no fixed implications about liability, authority to contract on another's behalf, or fiduciary duty. In law, partners bear mutual agency power and unlimited personal liability (unless the partnership form limits this), making the label legally consequential in ways casual usage does not suggest. A person who holds themselves out as a partner — or allows others to do so — can be bound by firm obligations even without a formal agreement.

Recognized Forms
/SUBTYPES
General partners: Partners whose liability for partnership debts is unlimited and joint and several. Each general partner has full agency authority to act on behalf of the firm.
Ostensible partners (also called nominal partners): Persons whose names appear to the world as partners — whether by their own acts or by being held out as such — but who may have no actual interest in the firm. They are liable to third parties who rely on that appearance regardless of their actual status.
Dormant or secret partners: Persons with an actual ownership interest in the firm whose participation is not publicly disclosed. They are bound by partnership obligations but do not appear to third parties as partners.
Limited partners: Partners in a limited partnership whose liability is capped at their contributed capital, provided they do not participate in management. Distinct from general partners and governed by separate statutory frameworks (e.g., RULPA, ULPA 2001).
Domestic partners / civil union partners: In family law contexts, individuals in state-recognized non-marital relationships. Rights and obligations vary substantially by jurisdiction.

Why It Matters in Research
The word "partners" in historical sources almost always refers to general partners in a common-law partnership, with no limitation of liability unless the text explicitly signals otherwise. Researchers reading nineteenth- and early-twentieth-century materials should not assume that "partners" encompasses limited partners — limited partnership statutes were adopted unevenly across states and the concept was not universal.
The ostensible/nominal partner distinction is a recurring trap. Bouvier's entries make clear that persons can be held liable as partners purely by virtue of how they presented themselves or were presented to the public, without any actual agreement or interest. Historical cases involving creditors of dissolved firms frequently turn on this doctrine. A researcher tracing partnership liability disputes must examine not only the formal partnership agreement but all conduct and representations that might create apparent partnership status.
The historical sources collected here reflect common-law partnership doctrine, largely predating the Uniform Partnership Act (1914), the Revised Uniform Partnership Act (RUPA, 1994/1997), and modern limited liability partnership statutes. RUPA significantly altered several common-law rules — most notably by treating the partnership as a legal entity separate from its partners for most purposes, and by restructuring the rules on partner dissociation and firm dissolution. Researchers cannot assume continuity between pre-UPA case law and current doctrine.
In the Law Mind corpus, "partners" appears in both business organization materials and family law materials. The family law usage — domestic partners, cohabiting partners — is almost entirely a post-1970s development and will not appear in historical dictionary sources at all. The Law Mind Family Law Encyclopedia entries on palimony and unmarried cohabitants address this modern usage and its property and support implications.
One partner's authority to bind the firm — through deeds, mortgages, acknowledgments, and distress — was heavily litigated in the nineteenth century, and the historical sources here reflect that litigation. Researchers working on questions of partnership authority should treat the Bouvier's excerpts as illustrative of the common-law baseline against which statutory modifications must be measured.

Historical Dictionary Support
Black's Law Dictionary defines partners as "persons who have united to form a partnership in business; members of a firm," and distinguishes ostensible partners (name appears publicly, bound regardless of actual interest) from dormant or secret partners (interest concealed from the public). This two-part typology is the foundation of the historical analysis.
Bouvier's Law Dictionary provides a richer typology, distinguishing general partners (unlimited liability), ostensible partners (apparent to the world and actually such), and nominal partners (held out as partners but with no actual interest, potentially liable by their own acts). Bouvier's is consistent with Black's on the core distinction but adds the nominal partner category explicitly — a useful source for tracing that doctrine historically.
Bouvier's extensive treatment of partner authority covers a range of firm acts: acknowledgment of deeds, distress under leases, disposition of firm property, majority rule on business decisions, and the limits of implied mortgage authority. The materials reflect both English and American case law from the mid-nineteenth century, flagging areas where American courts diverged from English precedent (particularly on the power of the majority to alter business arrangements).
Neither Black's nor Bouvier's addresses limited partnerships in the excerpts available here, domestic partnerships, or the RUPA entity-theory framework — all of which postdate or fall outside the scope of the historical sources. Researchers should not infer from silence that these concepts were unavailable; rather, they must consult supplementary statutory and treatise materials for those dimensions.

Jurisdictional Note
Partnership law in the United States is primarily state law. Most states have adopted some version of UPA or RUPA, but significant variations persist in how states treat partner liability, dissociation, and the rights of limited and limited liability partners. Family law recognition of domestic partners and civil union partners varies sharply by state and has been subject to rapid legislative change.
