Definition
Quia Emptores (Latin: "because the purchasers") is an English statute enacted in 1290 during the reign of Edward I (18 Edw. I, c. 1), also known as the Statute of Westminster III. It fundamentally restructured the feudal land tenure system by prohibiting subinfeudation and replacing it with substitution as the only permissible method of conveying freehold land.
Under the feudal system as it existed before 1290, a tenant holding land from a lord could transfer part of that land to a new holder who would then hold directly from the transferor — creating a new rung on the feudal ladder and diminishing the superior lord's rights (a process called subinfeudation). Quia Emptores abolished this practice for tenants of common lords and instead required that any transfer of land operate by substitution: the buyer steps into the seller's position in the existing tenurial chain, holding directly from the seller's lord on the same terms the seller had held.
The statute thus had two interlocking effects:
1. It prohibited subinfeudation — no new tenures could be created below the existing holder.
2. It freed tenants to alienate their lands without the lord's consent, in exchange for surrendering the power to create mesne (intermediate) tenures beneath themselves.
Common Confusion
Quia Emptores is sometimes confused with the earlier Statute of Mortmain (1279) or the general body of Edwardian land legislation. It is also occasionally misread as a statute protective of lords' interests. In fact, the statute served competing interests simultaneously: lords gained by preventing the dilution of their feudal rights through subinfeudation; tenants gained the right to freely alienate land without seeking their lord's license. Neither side obtained an unambiguous victory.
The statute also should not be confused with De Donis Conditionalibus (1285), which addressed entailed estates and the creation of fee tail, a distinct problem in the same reform era.
Why It Matters in Research
Quia Emptores has exceptional longevity. Because it was never formally repealed in England and was received as part of the common law in most American jurisdictions, its doctrinal footprint appears across centuries of property law materials — often without being named. Researchers working in:
— Medieval and early modern English land law will encounter the statute directly, but its effects are embedded in virtually every discussion of tenure, seisin, and conveyancing practice.
— American property law sources frequently invoke its principles when discussing the fee simple absolute and the impossibility of creating new feudal tenures. Courts in property disputes, particularly those involving future interests or the nature of freehold estates, sometimes reason from Quia Emptores without citing it by name.
— Historical sources use inconsistent terminology. "Subinfeudation," "substitution," "alienation in mortmain," and "free alienation" appear in overlapping and sometimes contradictory ways in older treatises. Researchers must track which practice a source is describing.
— A critical trap: the statute applied only to tenants holding of common lords — not to tenants-in-chief (those holding directly from the Crown). The Crown's tenants still required royal license to alienate until the Tenures Abolition Act 1660 (12 Car. II, c. 24). Older sources sometimes obscure this distinction, which materially affects research into Crown grants and royal land law.
— American reception is uneven. Some states received Quia Emptores as part of the common law; others modified or rejected its application by statute. Researchers using American property treatises should not assume uniform reception.
Historical Dictionary Support
Both editions of Black's Law Dictionary reproduce essentially the same entry, defining Quia Emptores by its Latin phrase ("because the purchasers") and summarizing its dual operation: removing the power of subinfeudation and substituting in its place a general right of free alienation by substitution. The entries are accurate as far as they go but are brief to the point of incompleteness. Neither edition addresses:
— The statute's application only to common tenants (not tenants-in-chief).
— The long-term doctrinal consequence: the progressive collapse of the feudal pyramid, since existing tenures could not be multiplied but were steadily extinguished by escheat and merger.
— The American reception question.
Older property treatises — particularly Blackstone's Commentaries (Book II) and Coke upon Littleton — provide far richer analysis of the statute's operation and are the appropriate starting point for serious historical research. Pollock and Maitland's History of English Law treats the statute in its political and tenurial context with a depth no law dictionary entry approaches.
Jurisdictional Note
Quia Emptores was received as part of the common law in most American states but is not universally applicable. A handful of states modified its operation by early statute, and its practical relevance varies depending on whether a jurisdiction retains any vestige of feudal tenure analysis. English law subsequently addressed feudal tenure more comprehensively through the Law of Property Act 1922 and related legislation; researchers working in modern English property law will find Quia Emptores significant historically but largely superseded in practice.
