Definition
A fiction of law by which courts presume that a valid grant of a property right — most commonly an easement or other incorporeal hereditament — was once formally made and has since been lost, in order to justify long-continued enjoyment of that right. When a party has exercised a right openly and without interruption for a significant period, but cannot produce any document of title, courts historically invoked the presumption of a lost grant to supply the missing legal foundation. The presumption is rebuttable: if the circumstances make it impossible that such a grant could ever have existed (for example, because the grantor lacked capacity at all relevant times), the fiction will not be applied.
Lost grant is distinct from prescription in its theoretical mechanism: prescription operates by analogy to the statute of limitations, treating long use as extinguishing the owner's right to object; lost grant instead supplies a positive origin story — a deed that once existed and was duly executed but has disappeared from the record.

Common Language
Modern common usage (Wiktionary): No standard entry. The phrase is not used in ordinary English outside a legal context.
Historical common usage (Webster's 1913): Not defined. Both component words appear separately — "lost" as mislaid or no longer possessed, "grant" as something formally conveyed — but the compound has no lay usage.
The editorial note here is brief but important: a lay reader encountering "lost grant" might assume it describes a grant of money or privilege that went missing. In law, the term is a term of art describing a legal fiction used to establish title or an incorporeal right, not a description of any physical document's whereabouts.

Common Confusion
Lost Grant vs. Prescription: These are the two competing doctrines for establishing long-enjoyed rights without documentary title, and they are frequently conflated. Prescription is grounded in statute or common law limitation periods and treats continuous use as the right itself ripening into enforceable title. Lost grant is a common law fiction that assumes a formal deed once existed. In practice, courts and practitioners sometimes use the terms interchangeably, but they rest on different theoretical premises and can produce different outcomes — particularly where the grantor's legal capacity or the nature of the interest makes a past grant theoretically impossible, in which case prescription may survive where lost grant cannot.
Lost Grant vs. Adverse Possession: Adverse possession operates against possessory interests in land and vests fee simple (or leasehold) title after statutory periods. Lost grant is typically invoked for incorporeal rights — easements, profits, and similar non-possessory interests — where adverse possession doctrine does not straightforwardly apply.

Why It Matters in Research
Lost grant is a doctrine built for historical sources, which makes corpus navigation non-trivial.
First, the doctrine's prominence is inverse to its modernity. In England, the Prescription Act 1832 largely displaced lost grant as the operative framework for acquiring easements by long use, supplanting the fictional presumption with a statutory scheme. Post-1832 English materials therefore treat lost grant as residual or obsolete doctrine, while pre-1832 materials treat it as the primary vehicle. American jurisdictions did not uniformly adopt the Prescription Act's framework, so lost grant remained active in American case law well into the twentieth century — but with significant variation by state. A researcher reading English and American sources together must be alert to this divergence.
Second, the fiction's operation is often implicit rather than explicit in older opinions. Courts sometimes invoke the presumption of a lost grant without naming it, simply reasoning that long enjoyment raises a presumption of lawful origin. In the Law Mind corpus, this means relevant materials may be indexed under easement creation, prescription, or incorporeal hereditaments without the phrase "lost grant" appearing in the text.
Third, the doctrine intersects tightly with the rules governing what constitutes sufficient use to trigger the presumption — continuity, openness, adverseness — which are the same factors governing prescriptive easements. Researchers tracing the elements of either doctrine will find the authorities intermingled.
Fourth, watch for the doctrine being invoked in franchise and public right cases, not merely private easement disputes. Courts have applied lost grant reasoning to support long-exercised public or quasi-public rights.

Historical Dictionary Support
Rapalje & Lawrence provide the critical orienting note: "In England, before the Prescription Act (q. v.), a claim to an [incorporeal hereditament by long enjoyment was supported by the presumption of a lost grant]." The entry is brief but accurate in its core point — the doctrine is fundamentally pre-statutory in the English context, and the Prescription Act is the watershed. The historical dictionaries treat lost grant as a settled common law doctrine requiring no extended definition, which is itself instructive: by the time these dictionaries were compiled, the doctrine was well enough established that its outlines were assumed to be familiar.
What historical sources tend to understate is the doctrine's continuing vitality in American jurisdictions after the English statutory reform, and the degree to which American courts simultaneously invoked both lost grant and prescription without always distinguishing between them. Researchers should not treat the Rapalje & Lawrence framing as a complete picture of the doctrine's American trajectory.

Jurisdictional Note
American states vary considerably. Many retained lost grant as an independent common law theory alongside prescriptive easement doctrine; others collapsed the two into a single prescription framework. A few states rejected the lost grant fiction explicitly, preferring to ground long-use rights entirely in statutory limitation periods. Research in any specific jurisdiction requires checking whether lost grant remains a recognized theory of title or has been absorbed into prescription.
