Definition
Delectus personae (Latin: "choice of person") is a doctrine holding that membership in a partnership or similar personal association cannot be transferred to a third party without the consent of all existing members. Because each partner is chosen for their personal qualities — skill, trustworthiness, reputation, financial standing — no partner may substitute another person in their place, nor may a partner's interest in the partnership itself (as distinct from their share of profits) be assigned so as to make the assignee a partner. The doctrine reflects the fundamentally personal nature of the partnership relationship: partners choose one another, and that choice cannot be overridden.
In practical terms, delectus personae means two things. First, a new partner cannot be admitted without unanimous consent of the existing partners unless the partnership agreement provides otherwise. Second, when a partner dies, becomes incapacitated, or withdraws, the original partnership is dissolved, because the personal association that defined it no longer exists in its original form.
Common Confusion
Delectus personae governs membership in the association, not transferability of economic rights. A partner may freely assign their economic interest — their right to receive a share of profits and surplus — to a third party without triggering delectus personae. What the assignee does not receive is the right to participate in management, inspect books, or become a partner. Researchers sometimes conflate assignment of a partnership interest with admission as a partner; these are distinct acts governed by different rules.
The doctrine is also occasionally confused with restrictions on share transferability in close corporations. While the underlying policy concern is similar — preserving the character of a small, personally chosen association — corporate law addresses this through shareholder agreements and statutory restrictions on transfer, not through delectus personae as such. The doctrine is a creature of partnership law.
Why It Matters in Research
Delectus personae is a load-bearing concept in partnership law, and its practical weight has shifted significantly across time and across statutory regimes. Researchers working with pre-Uniform Partnership Act materials will find the doctrine stated as an absolute common law rule with few qualifications. Under the Uniform Partnership Act (1914) and its successors — the Revised Uniform Partnership Act (1994, amended 1997) — the doctrine is preserved but increasingly subject to override by partnership agreement, particularly in the context of limited liability partnerships and limited partnerships.
The key research trap: older cases and treatises treat dissolution upon a partner's death or departure as an automatic, non-waivable consequence of delectus personae. Modern uniform act jurisdictions have substantially modified this, allowing partnership agreements to provide for continuation. When reading historical equity decisions involving partnership dissolution, understand that the court may be applying a stricter version of the doctrine than any current statute would recognize.
In limited partnership law, the doctrine applies asymmetrically. Limited partners historically had no management role and therefore no delectus personae claim over who became a fellow limited partner; the doctrine protected general partners, not limited partners. This asymmetry appears in early uniform limited partnership acts and is worth tracking in historical sources.
The doctrine also surfaces in professional partnership contexts — law firms, medical practices, accounting firms — where admission of new partners implicates both the common law rule and, in some jurisdictions, professional responsibility rules that independently restrict who may share in firm ownership.
Historical Dictionary Support
Rapalje & Lawrence give only the bare translation — "the choice of a person" — and identify it as an established principle of the common law, without elaborating on its operation or limits. This brevity is characteristic of the 1883 source and reflects an era when the doctrine was treated as settled and self-explanatory among legal practitioners. What the entry misses entirely is the tension the doctrine creates in commercial contexts where partnership interests are pledged as security or pass by operation of law to heirs or trustees in bankruptcy — questions that occupied courts extensively in the late nineteenth and early twentieth centuries.
Earlier English equity jurisprudence, synthesized in treatises by Lindley on Partnership, provides the fullest historical treatment. Lindley's analysis makes clear that delectus personae was not merely a rule of convenience but a structural premise of partnership: the partnership relation is personal and consensual at its core, distinguishing it from corporate membership, which is freely transferable absent restriction. This distinction drove much of the nineteenth-century debate over whether partnerships could be made to survive individual partners' deaths by contract, and courts were divided until statutory reform settled the question in most jurisdictions.
Jurisdictional Note
The doctrine is recognized across common law jurisdictions but its consequences differ by statute. In U.S. jurisdictions that have adopted the Revised Uniform Partnership Act, partnership agreements may significantly modify or eliminate the dissolution consequences that historically flowed from delectus personae. Scottish law, from which some of the doctrine's most precise formulations derive, treats it similarly but within a distinct partnership statute. Researchers working across jurisdictions should not assume that the common law baseline stated in older dictionaries reflects current operative law anywhere.
