Definition
A procedural device in civil law practice by which a defendant brings a demand or action against the plaintiff before the same judge and in the same proceeding. Rather than initiating a separate lawsuit, the defendant asserts an affirmative claim arising from the same dispute — or one sufficiently connected to it — within the existing litigation.
Reconvention is broader than a simple setoff. Where setoff is limited to liquidated or closely matched money demands, reconvention permits the defendant to seek affirmative relief on any claim that is necessarily connected to the main action and incidental to the same proceeding. The essential requirement is that the reconventional demand be related to the principal claim — not merely any grievance the defendant holds against the plaintiff.
In American practice, reconvention is a term of art primarily confined to Louisiana and Texas, both jurisdictions with civil law roots. In common law states, the functional equivalent is the counterclaim.

Common Language
Modern common usage (Wiktionary): "An action brought by the defendant against the plaintiff before the same judge."
Historical common usage (Webster's 1913): "A cross demand; an action brought by the defendant against the plaintiff before the same judge."
The common-language and legal definitions here are unusually close, because both Webster's and Wiktionary draw directly from legal sources. The gap that matters is not between lay and legal meaning, but between reconvention and its common law analogues — counterclaim and setoff — which a researcher may assume are interchangeable. They are not. See COMMON CONFUSION below.

Common Confusion
Reconvention vs. Setoff: Black's expressly states that reconvention "is not identical with set-off, but more extensive." Setoff historically required the defendant's cross-demand to be a liquidated, independent debt capable of extinguishing the plaintiff's claim. Reconvention permits a wider range of affirmative demands, including claims for unliquidated damages, so long as the demand is connected to and incidental to the main action.
Reconvention vs. Counterclaim: In modern federal and common law state practice, the counterclaim (Rule 13 of the Federal Rules of Civil Procedure) has absorbed and largely replaced both setoff and reconvention as procedural categories. A researcher working in Louisiana materials must resist mapping "reconvention" onto "counterclaim" without examining whether the civil law connectivity requirement imposes a different threshold than Rule 13's permissive and compulsory counterclaim framework.

Core Elements
Louisiana's Code of Practice (as cited in Bouvier) articulated the classic requirements for a valid reconventional demand:
1. There must be a pending principal action in which the reconvening party is the defendant.
2. The reconventional demand must be brought before the same judge.
3. The demand, while different from the main action, must be necessarily connected with it and incidental to the same proceeding.
The third element is the operative limit. A defendant cannot use reconvention to import an entirely unrelated grievance into the litigation. The connection requirement distinguishes reconvention from a permissive counterclaim as understood in common law systems.

Why It Matters in Research
Jurisdictional isolation is the central research hazard. Because reconvention is a civil law procedural concept, it appears substantively in Louisiana and Texas materials but is largely absent from common law state sources. A researcher working in 19th-century Texas litigation records or Louisiana appellate opinions will encounter the term routinely; a researcher in contemporaneous New York or Massachusetts materials will not. Applying common law counterclaim doctrine to interpret reconvention references in civil law sources will produce distorted results.
The relationship to setoff deserves particular attention in historical research. Pre-20th-century sources — including several of the historical dictionaries in this corpus — sometimes treat reconvention, setoff, and cross-demand as rough synonyms. Black's explicit correction ("not identical with set-off, but more extensive") is a useful anchor, but researchers should expect inconsistency in period usage, especially in lower court records and practitioner materials outside Louisiana.
Texas practice presents a transitional complexity. Texas began as a civil law jurisdiction (under Spanish and then Mexican authority) and retained reconvention as a procedural category into the statehood period. As Texas courts moved toward common law procedural frameworks over the 19th century, reconvention gradually gave way to counterclaim terminology. Researchers working the Texas materials should track which procedural era a given source inhabits.
In Louisiana, reconvention survived far longer as a distinct legal category and retains some analytical presence in Louisiana civil procedure today, though the Louisiana Code of Civil Procedure now uses "reconventional demand" as the governing term, modernizing but preserving the civil law concept.
Anderson's Dictionary raises a subtle substantive point worth flagging: a defendant's assertion of a reconventional demand does not waive or abandon other defenses, including the defense that the underlying contract is unlawful. A defendant may simultaneously argue the contract is void and, in the alternative, claim damages for the plaintiff's breach of that same contract if it were valid. This layered pleading posture could confuse researchers expecting reconvention to function as an admission of the contract's validity.

Historical Dictionary Support
The five source dictionaries present a coherent but incomplete picture. Bouvier provides the most substantive treatment, citing the Louisiana Code of Practice directly and articulating the connectivity requirement with precision. Black's (both editions) correctly identifies the civil law origin and the critical distinction from setoff, though the 2nd edition adds a federal citation (Pacific Express Co. v. Malin) that reflects reconvention's appearance in appellate review of civil law state judgments — a useful pointer to where the concept reached federal attention.
Anderson adds the procedurally important point about non-waiver of defenses, which none of the other dictionaries address. This is a genuine contribution that goes beyond mere restatement of the definition.
Rapalje & Lawrence's entry is fragmentary — the printed text appears to have suffered a typographical corruption that merged the RECOGNIZOR entry with the RECONVENTION entry. The corpus entry for this source cannot be relied on independently; researchers should cross-reference Bouvier and Black's.
What all five sources understate is the procedural evolution: none addresses the eventual displacement of reconvention by the modern counterclaim framework in Texas, or the survival and codification of the concept in Louisiana civil procedure. For that trajectory, researchers will need to move beyond the historical dictionaries and into the Louisiana Code of Civil Procedure and its commentary.

Jurisdictional Note
Reconvention as a distinct procedural category is effectively limited to Louisiana in current American practice, where it survives as the "reconventional demand" under the Louisiana Code of Civil Procedure. In Texas and other former civil law jurisdictions, the concept was absorbed into common law counterclaim practice during the 19th and early 20th centuries. Federal courts sitting in diversity in Louisiana have applied the reconventional demand framework where Louisiana procedural law governs the form of pleading.
