Definition
A form of concurrent ownership in which two or more persons each hold a distinct, undivided fractional interest in the same property. Each co-tenant owns a share of the whole — not a physically separate piece — and each interest is independently alienable, devisable, and descendible. When one tenant in common dies, that person's interest passes through their estate (by will or intestacy), not automatically to the surviving co-tenants. There is no right of survivorship.
The shares need not be equal. A tenancy in common can be created among two or more persons holding one-half each, or among many persons holding wildly unequal fractions. What each co-tenant shares equally, regardless of fractional interest, is the right to possess and enjoy the whole property. No co-tenant can exclude another from any part of the property on the basis of their larger share.

Common Language
Modern common usage (Wiktionary): "A form of ownership by two or more individuals in which each owner has a distinct, separately transferable interest which does not pass to the other owner or owners upon death."
Historical common usage (Webster's 1913): Webster's 1913 does not carry a dedicated entry for tenancy in common, reflecting that the term functioned as legal terminology of art rather than general vocabulary.
The Wiktionary definition is unusually accurate for a legal term. The critical point a researcher should not overlook: "undivided" interest. Each co-tenant's fractional share is mathematically distinct but physically undivided — no co-tenant owns the north half of the land or the upper floor of the building until partition occurs. The legal concept of undivided interest governs who can sue, who must be joined, and how contribution and accounting work among co-tenants.

Common Confusion
TENANCY IN COMMON vs. JOINT TENANCY: The most frequent confusion in both lay documents and older legal instruments. Joint tenancy carries a right of survivorship — a deceased joint tenant's interest evaporates and augments the surviving joint tenants automatically, outside the estate. A tenancy in common carries no such right. In older deeds and conveyances, the presence or absence of words of survivorship ("to A and B as joint tenants and not as tenants in common") was controlling. Many jurisdictions now presume a tenancy in common unless joint tenancy language is explicit. Researchers working with historical conveyances must check the applicable presumption rule for the jurisdiction and era.
TENANCY IN COMMON vs. TENANCY BY THE ENTIRETY: Tenancy by the entirety is a joint tenancy available only to married couples. It carries survivorship rights and, critically, typically prevents one spouse from alienating or encumbering their interest without the other's consent. A tenancy in common imposes no such restriction. See property_12 (Concurrent Ownership — Tenancy by the Entirety).

Core Elements
Each element is legally operative, not merely descriptive:
1. UNITY OF POSSESSION: The only unity required. All tenants in common share the right to possess the whole. Unlike joint tenancy, unities of time, title, and interest are not required.
2. DISTINCT FRACTIONAL INTEREST: Each co-tenant holds a separately identifiable share, which may be equal or unequal to other shares, and which can be conveyed, mortgaged, or devised independently.
3. NO RIGHT OF SURVIVORSHIP: The defining structural difference from joint tenancy. A co-tenant's share descends to heirs or devisees, not to surviving co-tenants.
4. RIGHT TO CONTRIBUTION AND ACCOUNTING: Co-tenants who pay more than their proportionate share of taxes, carrying costs, or necessary repairs may have rights of contribution against other co-tenants. Co-tenants who exclusively occupy the property or collect rents may owe an accounting.
5. RIGHT TO PARTITION: Any co-tenant may compel partition — either physical division of the property (partition in kind) or forced sale with division of proceeds (partition by sale). Partition is a critical exit mechanism and frequently litigated.

Why It Matters in Research
The tenancy in common is the default concurrent ownership form in modern American law. When a deed or conveyance creates co-ownership without specifying the form, most contemporary jurisdictions presume tenancy in common. This presumption is relatively modern; researchers working with pre-20th century materials should not assume it applied.
HISTORICAL TRAP — THE PRESUMPTION REVERSAL: Common law originally favored joint tenancy. The shift toward a tenancy-in-common presumption occurred at different times in different American jurisdictions, often by statute. A researcher reading a 19th-century deed granting property "to A and B" cannot assume the modern presumption governs. The applicable state statute, its enactment date, and the deed's language must all be checked.
FRAGMENTATION PROBLEM: Tenancy in common interests can be repeatedly subdivided through inheritance and sale, producing fractional co-ownership among dozens or hundreds of parties — particularly common in heirship property situations, tribal lands, and estates that went unresolved over generations. This fragmentation is a documented obstacle to land use, financing, and title clearance. Researchers encountering fractional interest chains in property records should be alert to this structural dynamic.
PARTITION LITIGATION: Partition actions generate substantial case law and are a recurring site of equitable discretion. Whether a court will order partition in kind (preserving the land) versus partition by sale (liquidating it) is frequently contested and jurisdiction-sensitive. Researchers in the remedies corpus may also encounter tenancy in common in the common fund doctrine context — when co-tenants fund litigation that benefits the common property, fee allocation across interests can implicate doctrines tracked in remedies_65.
PROBATE INTERSECTION: Because a co-tenant's interest passes through the estate, tenancy in common creates repeated intersections with probate and estate administration. Title defects frequently originate in estates where the decedent's fractional interest was never formally transferred.

Historical Dictionary Support
Burrill's Law Dictionary defines tenancy in common as "the holding of an estate in lands by several persons," centering the definition on the plurality of holders and the shared estate — a formulation that accurately captures the core structure but does not foreground the critical distinguishing feature: the absence of survivorship. Burrill's era reflected a legal culture in which joint tenancy remained a live alternative requiring careful drafting to avoid, making the contrast with joint tenancy the practical center of gravity for any practitioner consulting the entry.
Black's Law Dictionary historically cross-referenced tenancy in common under the general "tenancy" cluster, consistent with the dictionary's organizational habit of defining the parent term and dispatching variants from there. The historical Black's entries are useful for tracing how the elements (particularly the unity of possession as the sole required unity) became standardized across American jurisdictions.
Neither historical dictionary adequately addresses the presumption shift favoring tenancy in common, because both were compiled during the transition period and reflect jurisdictional inconsistency. The modern researcher should treat historical dictionary statements about presumptions with caution and verify against applicable state statutes.

Jurisdictional Note
Most American jurisdictions now presume tenancy in common when a conveyance creates co-ownership without express language indicating joint tenancy or another form. Louisiana's civil law system uses different terminology and structural concepts (indivision rather than tenancy in common), and researchers working with Louisiana property law should not assume common law categories apply directly.
