Definition
Reditus albi (Latin: "white rent") is a historical term from feudal land law referring to rent payable in silver coin or its monetary equivalent. It stands in contrast to rents paid in kind — goods, labor, or agricultural produce — which characterized the more common forms of feudal obligation. The "white" designation refers to the color of silver, distinguishing this cash-based rent from rents rendered in darker commodities such as grain, livestock, or labor services.
Reditus albi is closely associated with the tenure known as blanche farm (or blanche ferme), the Anglo-Norman counterpart to the Latin formulation. Under that tenure, a tenant's annual obligation was discharged by a fixed silver payment rather than by personal service or produce.
Common Confusion
Reditus albi is sometimes loosely grouped with fee farm rents or other fixed monetary charges on land, but the terms are not interchangeable. Fee farm denotes a tenure in which land is held in fee simple subject to a perpetual rent, without reference to the silver-payment character of the obligation. Reditus albi identifies the nature of the payment medium — silver money — not the tenure structure itself. The two concepts can overlap (a fee farm rent could be a reditus albi), but neither subsumes the other. Researchers should also distinguish reditus albi from reditus nigri ("black rent," or blackmail in its original feudal sense), which referred to rent paid in goods, cattle, or labor rather than in coin.
Why It Matters in Research
This term appears almost exclusively in medieval and early modern sources and is unlikely to surface in any post-seventeenth-century legal materials in its Latin form. Researchers working in feudal tenure records, inquisitions post mortem, manorial surveys, or early English land grants may encounter it in Latin form or its Anglo-Norman equivalent blanche farm. When it appears, it signals that the instrument is describing a cash rent fixed in silver, which carries significance for understanding the economic character of the holding and the stage of commutation from labor services.
The practical research trap is treating reditus albi as a generic synonym for any fixed monetary rent. The term carries a specific historical meaning tied to the commutation of feudal services into silver payments — a process that varied considerably by region and period across English and continental feudal practice. In corpus materials, blanche farm is far more likely to appear in English common law sources than the Latin form, so researchers should run both search strings.
Jurisdictional variation also matters: the term is primarily a feature of English and Norman feudal law. Researchers working in Scottish, Welsh marcher, or continental European sources will encounter analogous concepts under different terminology, and the specific obligations attached may differ.
Historical Dictionary Support
Black's Law Dictionary provides the essential core: "white rent; blanche farm; rent payable in silver or other money." The entry is accurate but spare, and no historical dictionary in the Law Mind corpus elaborates further. This brevity reflects the term's status as a technical relic — sufficiently specialized that compilers recorded it for completeness rather than practical application.
What the historical dictionaries collectively omit is the economic and tenurial context that gives the term its significance. Reditus albi emerged as a product of feudal commutation — the gradual conversion of labor services and render-in-kind obligations into fixed money payments. Understanding the term properly requires that context, which no dictionary entry alone supplies. Researchers needing deeper treatment should consult historical treatises on feudal tenure rather than relying solely on dictionary sources.
Jurisdictional Note
Reditus albi and its counterpart blanche farm are principally English and Norman in origin. The concept has equivalents in other European feudal systems, but the specific terminology does not transfer directly. Within English law, the term is effectively obsolete as operative legal language by the post-medieval period.
