Definition
A Latin phrase meaning "I have him in readiness" or "I have ready." In historical common-law pleading and procedure, paratum habeo was the formal return made by a sheriff to a writ of capias ad respondendum, signifying that the defendant had been arrested and was in the sheriff's custody, ready to be produced before the court at the appointed time. The phrase functioned as an official certification — the sheriff's formal acknowledgment that he had secured the body of the defendant and stood prepared to deliver that person to the court's jurisdiction.
Common Confusion
Paratum habeo should not be confused with the related sheriff's return cepi corpus ("I have taken the body"), which signified only that the defendant had been physically arrested. Paratum habeo carried the additional representation that the defendant remained in the sheriff's readiness and control — that is, not merely apprehended but held and available for presentation. Nor should it be confused with non est inventus ("he is not to be found"), the return made when the sheriff could not locate the defendant to execute the writ at all. These three returns form a family of capias responses that researchers frequently encounter together in historical records; distinguishing among them is essential to understanding what stage of process had been reached in a given case.
Why It Matters in Research
Paratum habeo is a term a researcher will encounter almost exclusively in pre-twentieth-century materials — court records, pleading precedent books, and common-law procedure manuals from the English and early American tradition. By the time modern civil procedure codes replaced the common-law writ system (the Federal Rules of Civil Procedure in 1938, and state-level reforms at various earlier dates), the specific formulaic returns associated with capias practice fell out of active use.
Several navigational points matter for corpus research:
First, the phrase appears in its abbreviated or shorthand form in historical court records. Clerks copying sheriff's returns into record books sometimes wrote "par. hab." or rendered the full phrase in anglicized or partial form. Researchers working with digitized or transcribed court records should search for variant forms.
Second, paratum habeo is inseparable from the writ of capias ad respondendum — a writ commanding the sheriff to take the defendant's body to compel appearance in a civil action. Understanding the full capias procedure is prerequisite to understanding what this return meant in context. The writ itself, the possible returns to it, and the consequences of each return (including bail, commitment, or failure of process) formed an interlocking procedural sequence.
Third, the Rapalje & Lawrence entry (reproduced here in truncated form) situates paratum habeo as a return not only to the capias ad respondendum but apparently also to the capias ad satisfaciendum — the post-judgment writ to take the body of a judgment debtor. This is a meaningful distinction: the same phrase could appear at different procedural stages depending on which capias writ was at issue. Researchers should identify the underlying writ before interpreting the return's significance.
Fourth, American sources largely imported this terminology from English practice without modification. State court records from the colonial and early national periods will use the same Latin formulas found in English precedent books. The phrase carries no jurisdictional variation in meaning, though the procedural context (which writs were available, when capias lay in civil as opposed to criminal matters) varied by jurisdiction and period.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) and Rapalje & Lawrence are in agreement on the core meaning: paratum habeo is the sheriff's return affirming readiness to produce the defendant. Black's frames it specifically in the context of the capias ad respondendum; Rapalje & Lawrence appear to extend the usage to at least one additional capias form (the entry in the source material is truncated at "capias ad satis-," strongly suggesting capias ad satisfaciendum). This extension, if confirmed, is a useful refinement that Black's does not supply.
Neither source elaborates on the procedural consequences of this particular return — what the court did next, how bail interacted with a paratum habeo return, or how the return was entered in the record. For that level of detail, researchers should consult treatises on common-law pleading and practice, such as Tidd's Practice of the Courts of King's Bench and Common Pleas or Chitty's Treatise on Pleading, which provide the procedural architecture within which these returns operated. Historical dictionary entries on terms like this tend to define without contextualizing; the research value comes from reading paratum habeo inside its writ-system environment, not in isolation.
