Definition
A Latin procedural phrase meaning "I have him in readiness." N paratum habeo is the formal return made by a sheriff in response to a writ of capias ad respondendum, signifying that the defendant has been taken into custody and is prepared to be brought before the court. It represents the sheriff's official declaration that service of the capias has been accomplished and that the defendant is available for presentment.
Common Confusion
N paratum habeo should not be confused with the return of non est inventus ("he is not found"), which is the sheriff's return when the defendant cannot be located for service. The two returns are direct opposites in practical effect: n paratum habeo confirms successful execution of the writ, while non est inventus reports failure to locate the defendant. Researchers encountering sheriff's returns in historical pleading records should be alert to this contrast, as the choice of return determined the procedural course of the action.
Why It Matters in Research
This phrase appears almost exclusively in records of early common law civil procedure, particularly in actions at law where the capias ad respondendum was the standard writ for compelling a defendant's appearance. It will surface in historical court records, sheriff's return dockets, and pleading books from the English common law tradition and its American successors, primarily from the colonial period through the mid-nineteenth century. Researchers should be aware that the phrase belongs to the now-obsolete system of formal sheriff's returns tied to the writ system; following procedural reforms in England (the Common Law Procedure Acts, mid-nineteenth century) and in American states through the adoption of code pleading and later the Federal Rules of Civil Procedure, this language ceased to have practical currency. It is therefore a marker of older procedural records rather than modern practice. Anyone tracing a civil action through colonial or early republic court files may encounter this return as confirmation that the defendant was in the sheriff's custody at a specific point in the litigation timeline. The phrase is a navigational signal: its presence tells the researcher that the capias was successfully executed and that the record should reflect subsequent appearance or bail proceedings.
Historical Dictionary Support
Black's Law Dictionary provides the core entry: "I have him in readiness. The return by the sheriff to a capias ad respondendum, signifying that he has the defendant in readiness to be brought into court." This is a narrow, technically precise definition consistent with the phrase's singular procedural function. The historical dictionaries do not expand substantially on this entry, and there is little to diverge from: the phrase performed one specific task in one specific procedural context. What the dictionary sources collectively underscore is the tight relationship between the Latin return and the underlying writ — n paratum habeo has no meaning independent of the capias ad respondendum. Researchers should note that dictionary coverage of this phrase is thin beyond Black's, reflecting its status as procedural machinery rather than a substantive legal concept. Secondary treatise literature on common law pleading (such as Chitty on Pleading or Stephen on Pleading) provides fuller context for how such returns functioned within the broader writ system.
Jurisdictional Note
The phrase is a product of English common law procedure and was carried into American colonial and early state courts. Its use was confined to jurisdictions that retained the capias ad respondendum as a writ for civil process; by the late nineteenth century, procedural reform statutes had replaced or renamed the underlying writ in most American jurisdictions, and the Latin return along with it.
