Definition
A reversion is the residue of an estate that remains in a grantor — or in the grantor's heirs — by operation of law, after the grantor has conveyed or devised a lesser estate out of a larger one. When the conveyed estate ends, the land does not pass to a new party; it returns to its source. No express provision is required to create a reversion. It arises automatically whenever an owner transfers an interest smaller than the owner's full estate.
Classic example: A landlord owns a fee simple and leases the property to a tenant for a term of years. The landlord retains a reversion. When the lease expires, possession reverts to the landlord without further conveyance.
The reversion is a present, vested interest even while the prior estate continues in possession. It is not merely a possibility or expectancy — the reversioner holds an actual estate in the land throughout the tenancy or lesser estate. This vested quality distinguishes it from a remainder, which is held by a third party, and from a possibility of reverter, which arises only on breach of a condition and is not regarded as vested in the same sense.
Common Language
Modern common usage (Wiktionary): "The action of returning to a former condition or practice." Also, in general usage: reversal, going back, undoing a change.
Historical common usage (Webster's 1913): "The act of returning, or coming back; return." Webster also notes the property-law meaning — "the returning of an estate to the grantor or his heirs, by operation of law, after the grant has terminated" — suggesting the legal meaning was already the dominant sense in formal usage by 1913.
Editorial note: In ordinary English, "reversion" often connotes undoing or regression — reverting a document, a policy, or a behavioral pattern. The legal meaning is narrower and more technical: it describes a specific present property interest, not a process or an action. A researcher encountering "reversion" in a non-property context should not assume the legal estate is meant.
Common Confusion
REVERSION vs. REMAINDER: Both are future interests, but a reversion is retained by the grantor while a remainder is created in a third party. If O grants "to A for life, then to B," B holds a remainder. If O grants "to A for life" and says nothing more, O holds a reversion. The distinction matters enormously in research: medieval and early modern sources use these terms with precision, but colloquial documents sometimes blur them.
REVERSION vs. POSSIBILITY OF REVERTER: A possibility of reverter arises when a fee simple determinable is granted — the fee automatically ends if a condition occurs, and the estate reverts to the grantor. But the grantor's interest before that condition occurs is not the same vested estate as a true reversion. Historically, the two were sometimes grouped together under "right of reverter," which creates confusion in older texts.
REVERSION vs. RIGHT OF RE-ENTRY (POWER OF TERMINATION): When a fee simple subject to a condition subsequent is granted, the grantor holds a right of re-entry, not a reversion or a possibility of reverter. These three future interests in the grantor are distinct, though earlier sources occasionally treat them loosely.
Core Elements
A reversion requires:
1. A prior estate in the grantor. The grantor must have held an estate capable of sustaining the lesser grant — typically a fee simple or fee tail.
2. Grant or devise of a lesser estate. The grantor conveys or devises a life estate, term of years, fee tail, or other estate of shorter potential duration than the grantor's own.
3. Operation of law. The reversion arises automatically; no language of reservation is needed.
4. Vested character. The reversion is a present vested interest, alienable, devisable, and descendible while the prior estate continues.
5. Natural termination of the prior estate. Possession shifts to the reversioner upon the natural end of the granted estate — expiration of the term, death of the life tenant, failure of the fee tail line.
Recognized Forms
/SUBTYPES
Grantor's reversion (the standard form): Arises when an owner grants a lesser estate and retains the residue.
Reversionary interest in landlord-tenant: The most common practical form in modern law. Every landlord who does not transfer a fee holds a reversion.
Testator's reversion (heirs' reversion): Where a testator devises a lesser estate and the residue descends to the testator's heirs by operation of law rather than by express devise.
Why It Matters in Research
Terminology drift across centuries: Blackstone, Coke, and the classical common-law sources use "reversion" with technical precision, but 19th-century American conveyancing documents, especially in frontier states, sometimes use it loosely to describe any future interest — including remainders and possibilities of reverter. A researcher reading deeds from that era should not assume the term carries its formal doctrinal weight.
Vested vs. contingent distinctions: The vested character of the reversion was heavily litigated in the Rule Against Perpetuities context. Because a reversion is vested, it is exempt from the Rule. Researchers working on perpetuities problems need to confirm whether the interest at issue truly is a reversion or whether it has been mislabeled — a mistake with significant practical consequences.
Landlord-tenant corpus connections: The reversion is the conceptual foundation of landlord-tenant law. Rent, covenants running with the land, and assignment rules all depend on the landlord's reversionary interest. Research into lease law, assignment and subletting, and landlord remedies will continually encounter reversion as the background concept.
Fee tail and its abolition: In jurisdictions that abolished the fee tail (most American states did so), language that would have created a fee tail typically converts to a fee simple absolute, eliminating the natural occasion for a reversion to the grantor's line. Historical property records from those jurisdictions may reflect a reversion that no longer functions as originally intended.
Adverse possession traps: The statute of limitations for adverse possession typically runs against the reversioner from the point the reversion falls into possession, not from the original grant. Researchers analyzing title chains must track when the prior estate ended to locate when adverse possession exposure began.
Historical Dictionary Support
The historical sources converge on the core definition without meaningful disagreement. Bouvier, Burrill, and both editions of Black's align with Blackstone (2 Bl. Comm. 175) and Coke (Co. Litt. 142b): a reversion is the residue of an estate remaining in the grantor after a lesser estate is carved out, vested by operation of law, commencing in possession on termination of the granted estate.
Burrill adds useful texture in tracing the term to the Latin reversio and grounding it in the physical image of land "returning" to the donor — an image that tracks the feudal logic of tenure, in which land granted by a lord was always understood as potentially coming back.
Black's (1st ed.) notes that the reversion is "deemed an actual estate in the land," citing Watkins on Conveyancing — a point the sources collectively emphasize to distinguish it from a mere expectancy. This characterization was important in determining the reversioner's rights during the pendency of the prior estate: the reversioner could bring actions to protect the land from waste, could alienate the reversion, and could mortgage it.
What the historical sources underemphasize: the increasing importance of the reversionary interest in commercial leasehold contexts, and the complications that arise when long-term ground leases or complex commercial arrangements leave the reversioner's interest economically attenuated. The classical dictionaries speak in terms of life estates and feudal grants; modern researchers applying reversion doctrine to 99-year ground leases or complex condominium conversions will need to supplement these sources significantly.
Jurisdictional Note
American states that abolished the fee tail by statute (the large majority) eliminated one of the primary occasions for a grantor's reversion to arise in the traditional sense. In those states, language that formerly would have created a fee tail and a corresponding reversion now typically vests a fee simple absolute in the grantee. Louisiana, as a civil-law jurisdiction, uses analogous but doctrinally distinct concepts; researchers should not import common-law reversion doctrine directly into Louisiana property analysis.
