Definition
A Roman civil law action available to a seller to recover the purchase price of goods sold and delivered to a buyer who has failed to pay. The phrase translates literally as "action upon sale" (from *actio*, action or lawsuit, and *vendito*, the ablative of *venditum*, a sale or thing sold). The actio ex vendito was the seller's primary remedy under Roman law when a completed sale had occurred and payment had not followed. It presupposed both a valid contract of sale (*emptio venditio*) and delivery of the goods. Also known as *actio venditi*.
Common Confusion
Researchers should not conflate the actio ex vendito with the *actio empti*, its counterpart. The actio ex vendito belongs to the seller; the *actio empti* belongs to the buyer. Both arise from the same underlying contract of *emptio venditio*, but they travel in opposite directions. Index entries and treatise discussions sometimes list them together without clearly differentiating the parties, which can mislead a researcher scanning for the buyer's remedy.
Why It Matters in Research
This term appears almost exclusively in texts treating Roman or civil law foundations — comparative legal history, Louisiana jurisprudence, Scottish law, and ecclesiastical court practice. Researchers encountering it in American or English legal sources before the mid-nineteenth century are likely reading a treatise author who is tracing the genealogy of contract and sales law back to Roman sources, not describing a remedy actually available in common law courts.
The distinction between actio ex vendito and common law assumpsit for goods sold and delivered is analytically important: though they accomplish similar ends, the Roman action arose from a consensual contract recognized as a specific legal category, while assumpsit developed from tort-like origins and did not require the same formal structure. Researchers working on the history of sales law, the development of the UCC's antecedents, or civil law jurisdictions should note that the actio ex vendito addressed price recovery only — the buyer's corresponding action for breach of warranty or non-delivery was the *actio empti*, a distinct remedy.
The term also surfaces in discussions of the distinction between real and personal actions in civilian taxonomy, where it serves as a stock example of a *personal* action (one arising from an obligation between parties, not a claim to property itself).
Historical Dictionary Support
Bouvier and Burrill are in complete agreement on this term, both defining it identically as "an action upon sale; an action which a seller is entitled to maintain against a buyer, to recover the price of a thing sold and delivered." Burrill adds the alternate name *actio venditi* and cites supporting sources: Justinian's *Institutes* (4.6.28), Heineccius's *Elementa Juris Civilis* (lib. 3, tit. 24, § 915), and the *Digest* (19.1) and *Codex* (4.49) — the core texts of the Corpus Juris Civilis. These citations point researchers directly to primary Roman law sources if deeper analysis of the original doctrine is needed.
Neither Bouvier nor Burrill attempts to map the term onto common law equivalents, which is appropriate given that the actio ex vendito is a concept native to the civilian tradition. What the historical dictionaries do not address is the procedural context: in Roman law, the *emptio venditio* generated reciprocal good-faith obligations (*bona fides*), meaning the actio ex vendito was not a purely mechanical debt-collection tool but carried equitable dimensions that common law assumpsit did not share in the same way.
