Definition
Amotion is the removal or dispossession of a person from a position, place, or property. The term carries three distinct applications in legal usage:
1. Real property. The wrongful dispossession of a landholder from possession of land before the natural expiration of their interest. In this sense, amotion is synonymous with ouster — Blackstone treats the two interchangeably, describing ouster as "an amotion of possession."
2. Personal property. The wrongful taking or carrying away of personal chattels. This usage overlaps with concepts underlying conversion and trespass de bonis asportatis, and reflects the term's older reach into personal property law.
3. Corporate law. The removal of a corporate officer or director from office before the expiration of the term for which they were elected or appointed. This is the application most likely to appear in cases and treatises from the nineteenth and early twentieth centuries, and the one most frequently cited in American legal sources.
Common Language
Modern common usage (Wiktionary): Removal; ousting; removal of a corporate officer from office.
Historical common usage (Webster's 1913): Removal; ousting; especially, the removal of a corporate officer from his office. Deprivation of possession.
The common and legal meanings here are unusually close, which reflects how thoroughly this Latin-derived term was domesticated into ordinary legal English. The gap worth noting is one of specificity: common usage treats amotion as a synonym for "removal" generally, while legal usage carries precise procedural weight — particularly in the corporate law context, where amotion describes a specific act requiring cause and proper authority, distinct from an ordinary resignation or expiration of term.
Common Confusion
Amotion is sometimes confused with ouster, and with good reason — historical sources use the terms interchangeably in the real property context. The distinction, where one exists, is one of framing: ouster typically describes the state of being dispossessed, while amotion emphasizes the act of removing or displacing. In the corporate context, there is no competing term, and amotion stands alone.
Amotion should also be distinguished from removal as used in modern corporate statutes, which typically provide a statutory procedure superseding the common law doctrine. Historical sources using "amotion" often describe common law corporate governance before such statutes existed.
Recognized Forms
/SUBTYPES
The three applications — real property dispossession, personal property wrongful taking, and corporate officer removal — are not subtypes of a unified doctrine but rather separate uses of the same Latin root, preserved in legal writing across different fields. The corporate law application is the one with genuine doctrinal development; the real property and personal property uses largely survive as historical reference points rather than operative legal categories.
Why It Matters in Research
Researchers encounter amotion most often in one of two contexts: nineteenth-century corporate law materials, where it describes the power of a corporation to remove its own officers, and historical real property materials echoing Blackstone's usage. The challenge is that the term travels between these contexts without warning, and an index entry for "amotion" in a treatise or digest may lead to material on corporate governance, land dispossession, or personal property depending entirely on the period and subject matter of the source.
In the corporate law context, the common law doctrine of amotion holds that a corporation has an implied power to remove an officer for cause, even absent express charter or bylaw authority. This doctrine was extensively litigated in American courts during the nineteenth century and is the primary reason the term appears in American legal materials at all. Researchers tracing the origins of modern corporate removal provisions in state statutes should treat amotion as the predecessor concept.
For real property researchers, amotion as a synonym for ouster appears primarily in sources drawing directly or indirectly on Blackstone. It is rarely the operative word in American cases after the early republic period; ouster, ejectment, and eviction take over the doctrinal vocabulary. Finding "amotion" in a real property source is usually a signal that the author is writing in a Blackstonian register.
The personal property application is the most historically obscure and the least likely to appear as a live issue. It surfaces in older pleading texts and should be understood as a precursor to the modern vocabulary of conversion and wrongful taking.
Historical Dictionary Support
The historical dictionaries are in close agreement on the structure of the term: all three applications — land, personal property, and corporate office — are recognized by Black's (both editions) and Burrill. Rapalje & Lawrence reduce it to bare etymology without elaboration, which understates the corporate law dimension. Anderson's emphasizes the real property application and links it to eviction, which is accurate but omits the corporate context almost entirely.
Blackstone's formulation — "ouster is an amotion of possession" — is the anchor citation in every historical source, and its persistence across dictionaries reflects how thoroughly the real property meaning was established in the common law tradition. The corporate law definition, by contrast, is developed in the dictionaries without a comparable classical citation, suggesting it developed as an applied usage rather than from a single authoritative source.
None of the historical sources grapple with what amotion requires procedurally in the corporate context — whether cause is needed, what notice is required, or how it interacts with charter provisions. For that material, researchers must move beyond the dictionaries to treatises on corporations, particularly nineteenth-century American works on private corporations.
Jurisdictional Note
The corporate law doctrine of amotion was applied in American courts without significant statutory framework through much of the nineteenth century. Modern corporate statutes in most U.S. jurisdictions now expressly address officer and director removal, and the term "amotion" does not typically appear in those statutes. English corporate law retained the term longer in its common law form.
