Definition
In property law, *questus* (also *quaestus*) refers to an estate or property acquired by a person through their own act — by purchase, grant, or other means of acquisition — as distinguished from property received by hereditary descent. The term captures the Roman and medieval distinction between what a person earns or obtains and what a person inherits.
Common Confusion
QUESTUS vs. HAEREDITAS: These two terms form a deliberate pair in medieval property doctrine. *Questus* is the acquired estate; *haereditas* is the inherited estate. Conflating them — or treating *questus* as a synonym for "inheritance" — inverts the meaning entirely. In historical sources, the distinction carries legal consequences: different rules of descent, different obligations to lords, and different treatment under warranty could apply depending on which category the land fell into.
Why It Matters in Research
Questus is a term of historical property law most commonly encountered in sources dealing with feudal tenure, descent, and inheritance. Researchers working in pre-modern English land law, or in treatises drawing on Roman and civil law foundations, will encounter it as a counterpart to *haereditas* (inherited estate). The practical significance lay in how estates of different origins were treated under rules of descent and forfeiture: property acquired by purchase could sometimes be devised or alienated differently than ancestral land held by descent.
The term appears rarely in American sources after the early nineteenth century, and by the time of modern codified property law it had been entirely displaced by plain-English categories such as "acquired property" or simply "purchased property." Researchers encountering *questus* in historical deeds, treatises, or court records should resist reading modern fee simple doctrine backward onto the term — the feudal context governing *questus* could impose different rules depending on tenure type, the presence of heirs, and local custom.
The Glanvill citation in Black's anchors the term firmly in twelfth-century English feudal jurisprudence. Researchers who need to trace how this distinction operated in practice should look to secondary treatments of feudal property law and to Littleton's *Tenures*, which addresses the distinction between purchased and inherited estates in the English common law tradition.
Historical Dictionary Support
Black's Law Dictionary defines *questus* as the estate a man has "by acquisition or purchase, in contradistinction to 'haereditas,' which is what he has by descent," citing Glanvill, Book 7, Chapter 1. This is a minimal but accurate entry — it correctly identifies the term's function as a binary counterpart within a specific conceptual framework inherited from Roman and civil law.
The historical dictionaries do not expand further, and this reflects the term's essentially technical and archaic character. No significant divergence exists among historical sources on what *questus* means; the concept is narrow and stable. What the historical dictionaries collectively miss is any treatment of how the distinction between acquired and inherited estates played out procedurally — particularly in actions concerning warranty, forfeiture to the lord, or the passage of property in fee tail. Those dimensions require consultation of Glanvill, Bracton, or Littleton directly.
The Latin dictionary entry — *questus* as a past participle of *queror* (to complain, to lament) — is a false cognate and irrelevant to the legal term. The legal *questus* derives instead from *quaero* (to seek, to acquire), and appears in legal Latin as *quaesitus* or *quaestus*, meaning "that which has been sought or obtained." Researchers should not be misled by the homophone.
Jurisdictional Note
The term belongs to the common law tradition derived from English feudal property law and has no operative significance in any modern American or Commonwealth jurisdiction. It appears exclusively in historical and scholarly legal sources.
