Definition
An obsolete Latin term from old English law denoting the executor of a last will and testament — the person appointed to carry out the directions of a deceased's will, administer the estate, and fulfill the testamentary obligations of the decedent.
The term is a Latinized form drawn from ecclesiastical and civilian legal vocabulary, reflecting the influence of canon law on early English probate practice, where the administration of estates fell under the jurisdiction of church courts.

Common Confusion
CECONOMICUS should not be confused with the Latin term oeconomus, from which it derives conceptual kinship. Both terms gesture toward a stewardship or managerial function, but in English legal usage ceconomicus carried the specific technical sense of testamentary executor rather than a general administrator or steward. Researchers encountering either term in ecclesiastical or early common law sources should confirm which office is actually being described from context.

Why It Matters in Research
This term is a relic of the period when English probate and testamentary jurisdiction was administered through ecclesiastical courts, and its appearance in a source is a strong indicator that the document is either ecclesiastical in origin, heavily civilian-influenced, or very early in the common law tradition.
Researchers working in medieval or early modern English legal records — particularly records touching church courts, probate registries, or canon law treatises — may encounter this term where later sources would simply say executor. The terminology shift tracks the gradual secularization of probate jurisdiction in England, culminating in the transfer of testamentary jurisdiction from ecclesiastical courts to civil probate courts in the nineteenth century.
Because the term is rare and archaic, it will not appear in most standard legal dictionaries after the early modern period. Its absence from later reference works does not mean the underlying concept changed — the office of executor persisted and evolved — but the vocabulary was abandoned as the civilian tradition receded from English legal practice.
Burrill's inclusion of this term alongside related archaic Latinisms and Old French forms (oeps, opus) signals a cluster of vocabulary associated with early will and estate administration. Researchers encountering ceconomicus should also inspect nearby text for related terms in the same register, as documents using this vocabulary are likely to contain other archaic forms requiring similar attention.

Historical Dictionary Support
Burrill's Law Dictionary is the sole source among standard historical legal dictionaries to record this term, attributing its definition to Cowell's Interpreter — itself one of the primary repositories of archaic and civilian-influenced legal vocabulary in the English tradition. This chain of attribution (Burrill citing Cowell) suggests the term had already become a scholarly curiosity rather than a term of active practice by the time either dictionary was compiled.
The entry in Burrill is notably spare: it identifies the term's linguistic origin (Law Latin), its jurisdictional context (old English law), and its meaning (executor of a last will and testament), then points to Cowell without further elaboration. No case law is cited, and no statutory authority is provided, which is consistent with the term's role as a descriptor of an office rather than a term of art with doctrinal content of its own.
Historical dictionaries broadly agree that the executor function was well established in English law from an early period, but the vocabulary used to describe it varied considerably depending on whether the source was common law, canon law, or civilian in orientation. Ceconomicus represents the civilian end of that spectrum.

Jurisdictional Note
This term is specific to old English law and its ecclesiastical court tradition. It has no recognized currency in American legal usage and is unlikely to appear in American primary sources. Researchers working in Scottish, Irish, or Continental ecclesiastical records should be alert to cognate terms in those traditions, which may differ in both form and precise meaning.
