Definition
A sole corporation is a legal entity consisting of a single natural person — and that person's successors in a particular office or position — incorporated by law to give the officeholder legal capacities that exist independently of any individual occupant. The office itself holds corporate status: property, rights, and obligations vest in the corporation (the office), not the individual who happens to hold it at any given moment. When one officeholder dies or departs, the successor steps into the same corporate identity without interruption.
The classic examples are public and ecclesiastical offices: a monarch, a bishop, a parish rector, a public official such as a postmaster. The sole corporation device solves a practical problem — how does land, endowment, or ongoing legal obligation survive the death of a sole human holder? By incorporating the office, the law creates perpetuity where natural persons cannot have it.
This distinguishes the sole corporation from both the aggregate corporation (which consists of multiple members simultaneously) and the ordinary individual acting in a personal capacity.

Common Language
Modern common usage (Wiktionary): "A corporation consisting of a single individual and their successors."
Historical common usage (Webster's 1913): Webster's 1913 does not carry a separate entry for "sole corporation," treating "sole" in its ordinary sense of "alone" or "single."
The Wiktionary definition is accurate as far as it goes, but the common reader will likely misread "sole corporation" as a synonym for what modern business law calls a single-member LLC or a one-person business. That reading is wrong in an important way: a sole corporation is not defined by having only one shareholder or owner — it is defined by the nature of the office itself being the corporate unit, with successors in that office automatically inheriting the corporate identity. The modern one-person business entity is a voluntary formation; the traditional sole corporation is typically a creature of law or royal charter attaching to a specific public or ecclesiastical role.

Common Confusion
SOLE CORPORATION vs. SINGLE-MEMBER LLC / ONE-PERSON CORPORATION: Modern researchers, especially those working with business organization materials, frequently conflate a sole corporation with a single-member LLC or a closely held corporation with one shareholder. These are fundamentally different structures. A single-member LLC is a voluntary contractual entity that dissolves or transfers on the member's terms. A sole corporation is an office-based entity in which succession is automatic and the corporate capacity attaches to the role, not the individual. A sole proprietor, by contrast, is not incorporated at all.
SOLE CORPORATION vs. CORPORATION SOLE: These two terms refer to the same concept and are used interchangeably in English legal literature. "Corporation sole" is the form most commonly found in ecclesiastical and constitutional law contexts; "sole corporation" appears more often in older common-law treatises and American digests. Researchers should search both forms.

Why It Matters in Research
The sole corporation is primarily a historical and ecclesiastical doctrine, and its practical significance in modern American commercial law is minimal. Researchers encounter it in three main contexts:
First, in historical property law: disputes over whether land or endowments held by a bishop, rector, or public officeholder passed as personal estate at death or remained with the office. Understanding the sole corporation concept is essential to reading those cases and conveyances correctly. Treating "the Bishop of X" as an individual rather than a corporation sole in an old deed can lead to a fundamental misreading of title.
Second, in constitutional and public law history: some American public offices have been argued to carry corporation-sole status derived from English common law. This surfaces in older state court decisions about the capacity of certain officers to sue, hold property, or bind successors by contract.
Third, in religious organization law: many U.S. states have statutes expressly authorizing religious corporations sole, allowing a bishop or presiding officer to hold church property in that capacity. These statutes vary considerably. A researcher working on church property disputes — especially those involving schisms or denominational splits — must identify whether the relevant officeholder holds property as a corporation sole under state statute, because that status determines who controls the property when leadership changes.
The trap in historical sources: older digests and encyclopedias treat the sole corporation as primarily an English ecclesiastical phenomenon and give little guidance on American statutory variants. Modern treatises on nonprofit and religious organizations are more useful for current American practice. Cross-check Black's against the relevant state's nonprofit corporation or religious corporation statutes.

Historical Dictionary Support
Black's Law Dictionary provides the foundational definition, tracing the concept to Stephen's Commentaries: a corporation comprising one person and successors, incorporated by law to confer perpetuity and other legal capacities unavailable to a natural person — citing the sovereign, bishop, and parson as archetypal examples.
This definition reflects the English common-law framework accurately. What historical dictionaries largely omit is the American statutory development: numerous states enacted religion corporation statutes in the nineteenth and twentieth centuries that codified the corporation sole for domestic religious use, modifying or displacing the common-law rules. Black's entry, like most historical dictionary treatments, presents the doctrine as if it were uniform common law, which understates the jurisdictional variation in modern American practice.
Historical sources also do not adequately address the question of whether a sole corporation can be created by private act in the absence of statutory authority — a live question in some American jurisdictions that requires consulting case law rather than dictionary sources.

Jurisdictional Note
Roughly half of U.S. states have statutes expressly authorizing the creation of a religious corporation sole, while others rely on common-law principles or have no clear authority. The scope of a corporation sole's powers — particularly regarding real property transactions, liability, and succession — varies significantly by statute. Researchers should not assume that the English common-law model governs in any particular American jurisdiction without checking the relevant state's nonprofit or religious corporation code.
