Definition
A Latin term from the civil law denoting a manager or administrator — a person entrusted with the care and management of property or affairs on behalf of another, an institution, or an estate. The economus occupied a supervisory or stewardship role, distinct from ownership, exercising practical control over assets or household affairs under delegated authority.
The term appears primarily in Roman civil law contexts and in medieval ecclesiastical and canon law, where it described officials charged with managing the temporal affairs of a church, monastery, or charitable institution. In this ecclesiastical usage, the economus functioned as a business agent or treasurer, responsible for the material administration of a religious body's property.

Common Confusion
Economus should not be conflated with executor or administrator in the modern probate sense. While all three involve managing property on behalf of others, an executor or administrator in modern law derives authority from a specific testamentary or judicial appointment within a defined legal process. Economus is a broader, more general Roman and canonical term for a manager or steward and does not carry the procedural specificity of its modern counterparts. Researchers encountering the term in historical sources should resist mapping it directly onto modern fiduciary categories.

Why It Matters in Research
This is a term of art encountered almost exclusively in translated Roman civil law sources, canon law texts, and early English legal treatises that draw on the civil law tradition. Researchers are unlikely to find it in common law cases or modern statutes.
The principal research trap is terminological: when reading civil law digests, ecclesiastical records, or early treatises in translation, economus may appear where a modern reader expects a word like trustee, administrator, receiver, or steward. These are not precise equivalents. Importing modern fiduciary concepts into the term distorts the historical meaning.
In canon law sources — particularly those dealing with the governance of ecclesiastical property — the economus held a recognized institutional role with defined duties under church governance structures. Researchers working in ecclesiastical law history, medieval institutional records, or the history of trusts and fiduciary obligation will find this term surfacing in that context.
Because the term is drawn from the civil law, it appears with greater frequency in Scottish, French, and Louisiana legal sources than in English common law materials. Researchers using Law Mind corpus materials focused on common law jurisdictions may encounter it only in treatises that engage the civil law tradition comparatively.
The term has no significant modern English legal usage. When it appears in a contemporary document, it is almost certainly a quotation from or direct reference to a classical or historical source.

Historical Dictionary Support
Both Rapalje & Lawrence and Burrill agree precisely: economus means "a manager or administrator" in the civil law, and both cite Calvini Lexicon Juridicum (John Calvin's legal dictionary, first published 1600) as their source. The brevity of both entries signals that neither compiler found the term in active common law use — it is recorded as a civil law import preserved in the learned tradition rather than as a living term of practice.
The reliance on Calvinus as the sole cited authority is itself informative. Calvinus's Lexicon was a standard reference for civil law terminology in the early modern period, and its citation here suggests the term reached English legal dictionaries through the civilian scholarly tradition rather than through direct judicial or statutory usage. Historical sources do not offer substantive treatment of the term's legal effects, duties, or procedural incidents — a gap that researchers should note when seeking to understand the full scope of the role in its original context. For that, primary civil law sources and canon law compilations are necessary.

Jurisdictional Note
Economus is a civil law term and as such is more likely to appear in sources from civil law or mixed jurisdictions — Louisiana, Scotland, Quebec, and jurisdictions whose legal systems derive from Roman or canon law — than in purely common law materials. Its ecclesiastical form remains relevant in canon law contexts across Catholic and some Anglican traditions.
