Definition
A term appearing in two distinct legal contexts in historical Anglo-American legal sources:
1. Spanish law: Money. The term was used in Spanish legal texts and codes that formed the basis of property and commercial law in territories governed by Spanish colonial rule — particularly relevant to the legal history of the American Southwest, Florida, Louisiana, and other former Spanish possessions. The compound phrase dinero contado (counted money, or money paid in hand) appears in transaction records and conveyances to indicate payment in specie rather than credit or deferred consideration.
2. Roman law: A civil administrative division of the Roman Empire, encompassing several provinces. This usage is confined to classical and ecclesiastical legal scholarship and has no direct operational significance in modern common law research.
Common Language
Modern common usage (Wiktionary): Money.
Historical common usage: Not entered in Webster's 1913. The term remained largely foreign-language vocabulary in English-speaking contexts.
The gap here is narrow but worth noting. In ordinary modern usage — particularly in American English — dinero is informal slang for money, borrowed directly from contemporary Spanish. In its historical legal context, the term functions as a term of art within Spanish law sources, signaling the applicability of Spanish legal codes and interpretive frameworks rather than simply meaning "cash." A researcher encountering dinero in a 19th-century land grant record or conveyance is being directed to Spanish legal tradition, not merely told that money changed hands.
Recognized Forms
/SUBTYPES
Dinero contado — Counted money; money paid in hand at the time of a transaction. Appears in conveyances and contracts governed by Spanish law to distinguish immediate cash payment from deferred or credit arrangements.
Why It Matters in Research
Researchers will encounter dinero almost exclusively in two contexts: historical Spanish land grant documents and classical Roman law scholarship. The practical research significance falls almost entirely in the first category.
Spanish land grants in what is now the United States — issued under the authority of the Spanish Crown and, later, the Mexican government — frequently used Spanish legal vocabulary that was then interpreted by American courts after the Mexican-American War and the various territorial cessions. Courts interpreting these grants often consulted treatises such as White's New Recapitulation of the Recopilacion de las Indias (cited in all three source dictionaries as White's New Recop.) to resolve questions about what Spanish-law terms meant at the time of the grant. A researcher working on title chains or property disputes with roots in former Spanish territories should treat dinero in source documents as a flag that Spanish law — not English common law — governs the interpretive framework for that transaction.
The Roman law meaning (an administrative province-like division) is purely taxonomic and appears in Calvin's Lexicon Iuridicum and similar classical references. It has no relevance to modern legal research and is included here only because it appears in Black's and Burrill without differentiation from the Spanish law definition — a potential source of confusion for researchers consulting those sources.
A trap in the historical sources: Black's 1st and 2nd editions present both the Spanish law and Roman law definitions as coordinate entries without signaling how vastly different their contexts and utility are. Burrill's entry is more circumspect, omitting the Roman law gloss entirely and anchoring the term firmly in Spanish law. Burrill's handling is the more useful guide for practical research.
Historical Dictionary Support
All three source dictionaries agree on the core Spanish law definition — dinero means money — and all cite the same authority: White's New Recop. b. 2, tit. 13, c. 1, § 1. This consistency reflects the narrow scope of the term's legal usage and the dominance of White's treatise as the standard English-language reference for Spanish colonial law in 19th-century American legal practice.
Black's (both editions) adds the Roman law definition, sourcing it to Calvin — almost certainly Johannes Calvinus's Magnum Lexicon Iuridicum, a standard reference for Roman and civil law terminology. Burrill omits this meaning without explanation, likely reflecting a judgment that the Roman law usage was too remote from practical legal research to warrant inclusion in a practitioner-oriented dictionary.
None of the three sources elaborate on the distinction between dinero in documentary versus statutory contexts, nor do they address how American courts treated Spanish monetary terms in land grant litigation. Researchers needing that depth should move from these dictionary entries to the underlying treatise and to reported decisions from former Spanish territory jurisdictions.
Jurisdictional Note
Relevant primarily to legal history and title research in states with Spanish colonial heritage: California, Texas, New Mexico, Arizona, Florida, and Louisiana. Courts in these jurisdictions historically applied Spanish law to transactions that occurred before American acquisition, and Spanish-language monetary terms in those records carry interpretive weight beyond their face meaning.
