Definition
Real property is land and everything permanently attached to or growing from it, together with the rights that arise from ownership of land. The category encompasses three traditional components: lands (the soil itself and what lies beneath and above it), tenements (interests in land held by another, such as leaseholds), and hereditaments (any property capable of being inherited, whether corporeal or incorporeal). Rights that issue out of land — such as easements, profits, and certain rents — are also real property even when they are not themselves physical.
The defining characteristic distinguishing real from personal property is immobility. Real property cannot be carried away; it is fixed to a location. Personal property, by contrast, is moveable. The line matters enormously in law: which court has jurisdiction, how property is transferred, how it passes at death, how it is taxed, and what formalities attach to conveyance all turn on this classification.
Common Language
Modern common usage (Wiktionary): Synonym of real estate; land, buildings, and similar property.
Historical common usage (Webster's 1913): Not separately defined as a legal term of art; "real" in common usage meant genuine or actual, from which the legal usage is entirely distinct.
The ordinary English association of "real" with authenticity is a false friend here. In law, "real" derives from the Latin res (thing) and specifically from the medieval distinction between real actions — suits to recover the thing itself — and personal actions — suits for damages. Real property is property recoverable by a real action. The word signals nothing about genuineness; it signals a category of legal remedy that has shaped property law for centuries.
Common Confusion
Real property and real estate are often used interchangeably in modern practice, but they are not identical. Real estate typically refers to the physical land and improvements. Real property is the broader legal concept: it includes real estate plus the bundle of legal rights attached to it — ownership interests, easements, mineral rights, air rights, and incorporeal hereditaments that have no physical form at all. A researcher treating the two terms as synonyms may miss incorporeal interests when searching historical sources.
Fixture is a persistent boundary problem. Personal property affixed to land can cross into real property depending on the manner of attachment, the intent of the annexing party, and the relationship between the parties. What is real property in a landlord-tenant dispute may be personal property in a secured transactions context. Do not assume fixture classification is uniform across legal contexts.
Core Elements
Three traditional subdivisions appear consistently across the historical sources:
Lands: The soil, the surface, the column of space above (to a legally recognized limit), and subsurface rights including minerals. The broadest and most fundamental category.
Tenements: Anything that may be held of another in a tenurial relationship. Includes not only physical land but leaseholds and certain incorporeal rights. Broader than "land" alone.
Hereditaments: Any property capable of descending to an heir. Further divided into corporeal hereditaments (tangible, visible property such as land and buildings) and incorporeal hereditaments (intangible rights running with land, such as easements, profits à prendre, rents, and certain franchises). This is where the concept of real property extends furthest from the physical.
Why It Matters in Research
The intestate succession rule is the historical anchor. Both Black's and Rapalje & Lawrence define real property by how it passes at death — to the heir, not the next of kin or administrator. This rule, inherited from English common law, shaped the definition for centuries and explains why the category was drawn so carefully. Researchers working with pre-twentieth-century American sources should expect the heir/next-of-kin distinction to appear wherever real property classification is at issue.
Incorporeal hereditaments are the most common research trap. Modern researchers focused on physical land will overlook offices, dignities, corodies, annuities, and similar interests that historical sources classify as real property. Bouvier flags offices and dignities specifically — interests classed as real property because they were historically annexed to land ownership, even though they are not land in any physical sense. These categories matter when tracing title disputes, inheritance conflicts, or franchise rights in older American and English sources.
The English rule on railway and canal shares — treating them as real property — appears in Bouvier and has no American counterpart. Researchers working in comparative or English legal history should note this divergence; American law consistently treated corporate shares as personal property.
Statutory redefinition is a significant research variable. Many American jurisdictions have modified the common law categories by statute. The New York Code reference in Black's signals that by the late nineteenth century, states were codifying and sometimes narrowing the definition. When working with statutes rather than common law sources, verify whether the jurisdiction's code tracks, expands, or contracts the traditional tripartite definition.
The fixture boundary generates the most modern research complexity. The Law Mind corpus contains fixture disputes across property, secured transactions, landlord-tenant, and tax contexts. Classification can differ within a single jurisdiction depending on which legal framework applies. A term search for "real property" will not surface all fixture cases, and a fixture search will not surface all real property analysis.
Historical Dictionary Support
The three historical sources converge on the core definition — lands, tenements, and hereditaments — and on the intestate succession rule as the organizing principle. This consensus reflects centuries of common law stability and can be relied upon as an accurate statement of the traditional doctrine.
Bouvier is the most expansive of the three, pushing into incorporeal hereditaments, the annexation-by-stranger rule, offices and dignities, corodies, annuities, and the English railway share question. Black's and Rapalje & Lawrence are more economical. For research into the outer boundaries of the category — particularly incorporeal interests — Bouvier is the essential starting point.
None of the historical sources address the fixture problem with the granularity modern practice requires, and none anticipate the secured transactions context in which fixture classification generates the most litigation today. The historical definitions are stable for core real property questions but should not be imported wholesale into modern UCC-adjacent research.
Jurisdictional Note
Louisiana treats real property under civilian doctrine rather than common law, with significant terminological and structural differences. Researchers working in Louisiana sources should not assume that common law categories — particularly incorporeal hereditaments — map cleanly onto civilian immovable property concepts. In most other American jurisdictions, the common law framework governs, subject to statutory modification that varies by state.
