Definition
The Assize of Utrum was a medieval English writ and judicial proceeding used by a parish parson to recover land that had been improperly alienated or lost by a predecessor in the church. The proceeding took its name from the Latin word *utrum* — meaning "whether" — reflecting the core question put to a jury: whether the land in dispute was held as lay fee or as frankalmoin (free alms), that is, whether it belonged to the church by ecclesiastical tenure or to a layperson by secular tenure.
In practice, the writ enabled a parson to bring a claim before a royal court to vindicate the church's title to land, particularly where a prior incumbent had allowed the land to slip into lay hands through neglect, alienation, or other improper dealing. The remedy was restorative: a successful claimant would recover seisin of the disputed land for the church.
The Assize of Utrum was sometimes called the "parson's writ of right" because it served a function analogous to the writ of right in ordinary fee disputes, but was tailored to the ecclesiastical context and the particular vulnerability of church lands to quiet attrition across successive incumbencies.
Why It Matters in Research
This term belongs firmly to the medieval stratum of English real property law and will appear almost exclusively in historical sources — Year Books, Bracton, Glanvill, and early common law treatises. Researchers working in ecclesiastical property disputes, medieval land tenure, or the history of frankalmoin tenure need to understand the Assize of Utrum as part of a cluster of specialized real actions that have no modern procedural equivalent.
Two traps await researchers in historical sources. First, the term "assize" carries multiple meanings in medieval law — it can refer to a legislative enactment, a court session, or a specific writ-based proceeding — and context is essential to distinguish them. The Assize of Utrum is the last of these: a specific form of action, not a statute or a sitting court. Second, the distinction between frankalmoin tenure and lay fee that sits at the heart of this proceeding was jurisdictionally charged: ecclesiastical courts claimed cognizance over frankalmoin disputes while royal courts handled lay fee. The Assize of Utrum was one of several mechanisms by which royal courts asserted or resolved this jurisdictional boundary, and its history is inseparable from the broader conflict between royal and ecclesiastical jurisdiction in medieval England.
Researchers tracing the decline of the real actions will find that the Assize of Utrum, like other ancient writs, fell into disuse well before the formal abolition of real actions in England in 1833. It has no American counterpart.
Historical Dictionary Support
Bouvier's treatment is brief: "A writ of assize which lay for a parson to recover lands which his predecessor had improperly allowed the church to be deprived of," citing Blackstone's *Commentaries* at 3 Bl. Com. 257. This single-sentence entry is accurate as far as it goes but strips away the jurisdictional and substantive context that makes the term meaningful.
Blackstone's own account in the *Commentaries* is richer, situating the writ within the conflict between royal and ecclesiastical courts over land held in frankalmoin. Blackstone notes that the action was triable before royal justices and that the jury's finding of whether the land was lay fee or frankalmoin determined which court would thereafter have jurisdiction. This procedural dimension — the writ as a jurisdictional sorting mechanism — is entirely absent from Bouvier.
Earlier authorities including Bracton and the treatment in Glanvill address the underlying tenure question in greater depth. Researchers requiring more than Bouvier's thumbnail should go directly to Blackstone and then to Pollock and Maitland's *History of English Law* for a full treatment of frankalmoin, the real actions, and the jurisdictional struggle that gave the Assize of Utrum its particular importance.
Jurisdictional Note
The Assize of Utrum is a creature of English medieval law with no reception into American jurisprudence. It is not operative in any current jurisdiction. Its relevance to American legal research is purely historical — primarily as background to the development of real property law and ecclesiastical tenure doctrine in the common law tradition.
