Definition
A writ of prohibition in English ecclesiastical practice, available to the patron of a church whose presented clerk (clergyman) is sued in the spiritual court by the clerk of another patron over tithes, when the value of those tithes amounts to at least one-fourth of the value of the living (benefice). The writ transfers the dispute from the ecclesiastical courts to the common law courts. Its authority derived from the Statute of Westminster II (13 Edw. I, c. 5). The writ takes its name from the Latin word "indicavit" — meaning "he has proclaimed" or "he has indicated" — which appeared as the emphatic operative word in the Latin form of the writ.
The writ functioned as a boundary-enforcement mechanism between two competing court systems in medieval and early modern England: the ecclesiastical courts, which claimed broad jurisdiction over tithes and church matters, and the common law courts of the Crown, which asserted authority once the dispute crossed a threshold of economic significance to the living.
Common Language
Modern common usage (Wiktionary): "A writ of prohibition against proceeding in the spiritual court in certain cases, when the suit belongs to the common-law courts."
Historical common usage (Webster's 1913): "A writ of prohibition against proceeding in the spiritual court in certain cases, when the suit belongs to the common-law courts."
Editorial note: Both common reference sources accurately capture the writ's function but elide the specificity that defines its legal operation. The indicavit was not a general-purpose writ of prohibition applicable to any ecclesiastical overreach — it was narrowly triggered by a patron's interest, a tithe dispute, and a precise quantitative threshold (the fourth-part rule). Researchers relying on Webster's or a general dictionary gloss will miss those elements entirely.
Core Elements
The writ required satisfaction of several distinct conditions:
1. A patron relationship. The party seeking the writ must be the patron of a church — that is, the holder of the advowson, the right of presentation to that living.
2. A presented clerk as defendant. The patron's own clergyman must be the party sued in the spiritual court, not the patron directly.
3. Suit by a rival clerk. The plaintiff in the ecclesiastical proceeding must be the clerk (clergyman) of another patron.
4. Tithes as the subject matter. The underlying dispute must concern tithes — the traditional church revenue.
5. The fourth-part threshold. The tithes in dispute must amount to at least one-fourth of the annual value of the benefice or living. Below that threshold, the spiritual court retained jurisdiction.
6. Statutory authority. Jurisdiction to issue the writ rested on the Statute of Westminster II (13 Edw. I, c. 5).
Why It Matters in Research
Structural pattern: Straightforward single-meaning, but with significant historical depth and a jurisdictional architecture that is easy to misread.
Researchers encountering indicavit in historical sources should keep several things in mind.
First, this is a purely historical English writ. It has no American counterpart and no continuing common law life in modern practice. Its appearance in American legal dictionaries reflects the comprehensive treatment those works gave to English legal history, not any transplantation of the doctrine to U.S. jurisdictions.
Second, the writ sits at the intersection of two significant historical subjects: the law of advowsons and patronage, and the longstanding jurisdictional competition between ecclesiastical and common law courts. Researchers working on either of those topics should treat indicavit as an index entry pointing toward that larger conflict, not as an isolated procedural curiosity.
Third, the fourth-part threshold is easy to overlook. The writ was not available for any tithe dispute touching a patron's church — only those where the contested amount crossed the statutory fraction. Below the threshold, the ecclesiastical court kept jurisdiction. This quantitative line was the mechanism by which Parliament allocated jurisdiction.
Fourth, the writ is patron-protective, not clerk-protective. It was the patron — the advowson holder — who had standing to seek the writ, because a tithe judgment against the patron's presented clergyman could diminish the value and attractiveness of the living, injuring the patron's property interest in the advowson. This standing structure is functionally significant and distinguishes indicavit from other prohibition writs.
Fifth, in corpus research, indicavit is most likely to appear in materials dealing with English ecclesiastical law, tithe law, advowsons, writs of prohibition, and the jurisdictional history of the common law courts. It surfaces regularly in Blackstone's Commentaries, Stephen's Commentaries, and the Registrum Omnium Brevium (Register of Writs).
Historical Dictionary Support
All four source dictionaries agree on the core definition: a writ of prohibition in tithe disputes, protecting the patron whose clerk is sued in the spiritual court, triggered at the fourth-part threshold, and authorized by the Statute of Westminster II.
The entries differ in emphasis. Black's (both editions) is the most concise, presenting the definition with reference to Blackstone and Stephen's Commentaries and noting the Latin etymological origin without elaboration. Rapalje & Lawrence add the standing rationale — that the patron has standing because a judgment against the presented clergyman prejudices the patron's interest in the advowson — a point the other dictionaries omit entirely and one that is substantively important for understanding the writ's purpose. Bouvier's frames the writ clearly around the king's courts versus ecclesiastical courts competition and cites Cowell's legal lexicon as authority.
None of the historical sources explain why the fourth-part threshold was set where it was, or trace the writ's later history. By the nineteenth century, the ecclesiastical court system was being systematically reformed, and the practical importance of writs like indicavit was fading. The dictionaries treat the writ as settled law without flagging this historical context.
Jurisdictional Note
Indicavit is exclusively a historical English writ with no recognized equivalent in American, Scottish, or other common law jurisdictions. Its relevance to American legal research is limited to historical and comparative contexts — tracing the reception of English ecclesiastical law doctrine, the law of advowsons in colonial practice, or the general history of prohibition writs.
