Definition
In law, immovable refers to property that cannot be physically relocated — land, buildings, and anything permanently attached to the earth. The term functions as a civil law equivalent to the common law concept of real property, though the two are not perfectly interchangeable.
Two senses operate in legal usage:
1. As an adjective: Describing property that is fixed to the ground and incapable of being moved without destruction or fundamental alteration of its character — principally land and structures permanently affixed to it.
2. As a noun (usually plural, immovables): A category of property in civil law systems encompassing land, buildings, standing timber, mineral rights, and certain incorporeal rights attached to land (such as servitudes and usufructs). Movables are the contrasting category, covering everything else.
The immovable/movable distinction is the organizing axis of property law in civil law jurisdictions (France, Louisiana, Quebec, Scotland, and most of continental Europe and Latin America). It performs the same classificatory work that real/personal property performs in common law systems, but the categories do not map cleanly onto each other.

Common Language
Modern common usage (Wiktionary): Something immovable; immovable objects or property, as land, buildings, etc.
Historical common usage (Webster's 1913): Incapable of being moved; firmly fixed; fast — used of material things. Also used figuratively of the mind or will: steadfast, unalterable, unimpressible.
The ordinary English sense captures the physical concept well enough but misses the legal significance entirely. In law, immovable is not merely a description of physical heaviness or attachment — it is a term of art that triggers a distinct body of rules governing acquisition, transfer, succession, and conflict of laws. A piece of farm equipment bolted to a concrete pad might colloquially seem immovable, but whether it legally qualifies as an immovable under civil law depends on factors of permanence, purpose, and intention that the common definition does not address.

Common Confusion
IMMOVABLE vs. REAL PROPERTY: Researchers moving between civil law and common law sources frequently treat these as synonyms. They overlap substantially but diverge at the edges. Civil law immovables can include certain incorporeal rights — servitudes, usufructs, and real actions — that attach to land. Common law real property doctrine handles these differently, often as interests in land rather than as a distinct property category. Do not assume a civil law source using "immovables" means exactly what a common law source means by "real property."
IMMOVABLE vs. FIXTURE: In common law jurisdictions, a fixture is personal property that has become so attached to real property that it is treated as part of the realty. Civil law systems achieve a similar result through the concept of immovable by destination (in French law, immeuble par destination) — movable objects permanently assigned to the service of an immovable. The doctrinal mechanisms differ even where outcomes converge.

Recognized Forms
/SUBTYPES
Civil law systems, following the French model, recognize at least three subcategories:
1. Immovables by nature: Land itself and buildings or structures permanently fixed to it.
2. Immovables by destination: Movable objects permanently placed on or in an immovable for its use and exploitation — farm animals, agricultural implements, pipes, machinery — treated as immovable by legal fiction to keep the productive unit intact.
3. Immovables by the object to which they apply: Incorporeal rights attached to land, including usufructs, servitudes, and real actions. These are immovable not because of physical attachment but because the right itself attaches to the immovable.

Why It Matters in Research
The primary research trap is source jurisdiction. A 19th-century American treatise using "immovable" may be drawing on civil law sources, French doctrine, or the law of Louisiana — or it may be using the word loosely as a synonym for real property in a common law context. Check the author's frame of reference before importing the analysis.
Louisiana is the critical domestic jurisdiction. Louisiana's civil law tradition means that cases, statutes, and secondary sources from that state use immovables doctrine natively and cannot be read through a common law lens without distortion. The Louisiana Civil Code's provisions on immovables (Articles 462–476) are the controlling framework there and differ materially from the common law of the other 49 states.
Conflict of laws research is particularly immovable-dependent. The traditional conflicts rule — that the law of the situs governs immovables — appears in both civil and common law systems, but which law applies and how the situs is determined can depend on whether the forum characterizes the property as immovable or movable. A researcher working on a cross-border succession or property dispute must determine how each jurisdiction involved defines the category.
Historical sources predating the consolidation of civil law codifications may use immovables inconsistently. Rapalje & Lawrence's terse entry ("not to be forced from its place — land") reflects the Anglophone understanding of the physical concept but does not engage the doctrinal architecture that civil law systems had already developed by the time of publication.
International private law sources — conflicts treatises, Hague Convention materials, comparative law scholarship — are the richest secondary literature on immovables doctrine. Researchers in domestic common law contexts who encounter the term in those sources should treat them as civil law materials and read accordingly.

Historical Dictionary Support
Rapalje & Lawrence's entry is minimal to the point of being a placeholder: "not to be forced from its place — land." It accurately identifies the physical characteristic but offers nothing of the doctrinal content. This reflects the marginal status of civil law concepts in 19th-century American legal dictionaries oriented toward common law practice. The entry would not help a practitioner working in Louisiana or advising on European property transactions.
What Rapalje & Lawrence miss: the movable/immovable classification system as an organizing framework, the subcategories by nature/destination/object, and the conflict of laws implications. For civil law doctrine, the historical dictionaries in the Anglo-American tradition are largely unhelpful; researchers should turn instead to French or Louisiana sources, or to comparative law treatises.

Jurisdictional Note
The immovable/movable distinction is operative law in Louisiana and in civil law countries worldwide. Common law jurisdictions use real/personal property instead, and the two frameworks diverge in how they treat incorporeal rights and property by destination. For international transactions or succession matters, characterization as immovable under the situs law may determine which country's law governs the entire dispute.
