Definition
In Roman civil law, a person described as *locuples* was financially able to satisfy a judgment — solvent, creditworthy, and good for whatever amount a plaintiff might recover in an action. The term functions as a descriptor of a party's capacity to respond in litigation, essentially a legal stamp of financial sufficiency. It carries no procedural mechanism of its own but appears in civil law texts as a qualifying characteristic, particularly when courts or parties assessed whether a defendant or surety could be relied upon to satisfy an obligation.
Why It Matters in Research
This is a narrow Latin civil law term with limited independent doctrinal weight. Researchers are most likely to encounter it in two contexts: (1) direct quotation or translation of Roman law sources, particularly the Digest, and (2) treatises on suretyship, bonds, or the qualification of witnesses and sureties in civil law jurisdictions, where financial responsibility was a formal prerequisite.
The key research trap is treating *locuples* as a term of art with a living common law equivalent — it has none. Common law systems addressed the same concern (a party's ability to satisfy judgment) through entirely different vocabulary: solvency, responsibility, sufficiency of surety, ability to respond in damages. If you encounter *locuples* in an English-language legal source, you are almost certainly in a civilian-influenced text, a comparative law analysis, or a historical treatise drawing on Roman sources. It signals the author's civil law grounding.
Researchers working in Louisiana, Quebec, or other mixed civil/common law jurisdictions may encounter the concept embedded in suretyship doctrine even when the Latin term itself is not used. The underlying requirement — that a surety or obligor be *locuples* — survived in substance even where the term did not.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in complete agreement on this term, both defining it identically: "able to respond in an action; good for the amount which the plaintiff might recover." Black's provides the Digest citation (Dig. 50, 16, 234, 1), anchoring the term directly in Justinian's compilation. Burrill's entry appears truncated in available sources but tracks the same meaning.
Neither dictionary elaborates beyond the bare definition, which is appropriate given the term's narrow scope. Neither source connects it to downstream common law concepts, and neither attempts a jurisdictional application beyond civil law. For a term of this vintage and specificity, the historical dictionaries do their job: they translate and cite. What they do not do — and what researchers should not expect — is explain how the concept migrated (or failed to migrate) into American or English practice.
The Digest reference is genuine and verifiable. Dig. 50, 16 is the title *De verborum significatione* (On the meaning of words), which is precisely where one would find definitional glosses of this kind in Roman law. That placement confirms *locuples* was understood as a term requiring formal definition even within the Roman system, not an everyday word whose meaning was assumed.
Jurisdictional Note
The term belongs to Roman civil law and has no recognized common law counterpart. Its practical relevance today is largely confined to civil law jurisdictions and to historical legal scholarship. Researchers working in Louisiana civil law materials or consulting pre-codification Spanish or French colonial sources may find the concept in functional use.
