Definition
A capias is a judicial writ commanding a law enforcement officer — historically the sheriff — to take a named person into physical custody. The word derives from the Latin imperative meaning "that you take," and the writ's operative force lies in that command: produce the body of the person named. Capias writs are the foundational mechanism by which courts compel physical appearance when voluntary compliance has failed or is not expected.
Several distinct writs travel under the capias name, each serving a different stage of legal proceedings:
1. Capias ad respondendum ("that you take to answer"): The standard pretrial arrest writ, commanding the officer to seize the defendant and bring them before the court to answer a civil or criminal complaint. This was the ordinary commencement of personal actions at common law.
2. Capias ad satisfaciendum (ca. sa.): A post-judgment writ directing the arrest of a judgment debtor who has failed to satisfy a civil judgment. This writ authorized body execution — the detention of a debtor — which was commonplace before debtor's prison reforms largely abolished the practice in the 19th century.
3. Capias ad computandum: Issued in actions of account, compelling a defendant to come before the court to render an accounting.
4. Capias pro fine: A writ to arrest a person who has failed to pay a court-imposed fine.
In modern American practice, the term capias survives primarily in criminal courts, where it functions as a bench warrant or arrest warrant issued by a judge — most often when a defendant fails to appear for a scheduled court date. The full Latin taxonomy has substantially collapsed; practitioners and statutes today frequently use capias and bench warrant interchangeably.
Common Language
Modern common usage (Wiktionary): An arrest warrant; a writ commanding officers to take a specified person or persons into custody.
Historical common usage (Webster's 1913): A writ or process commanding the officer to take the body of the person named in it, that is, to arrest him; also called writ of capias.
The common and legal definitions converge closely on the arrest function, but the common definitions flatten what was historically a family of distinct writs serving different procedural moments — before trial, after judgment, on failure to pay a fine. A researcher encountering a capias in historical records must determine which species of the writ appears, because each carried different legal consequences and belonged to a different procedural posture.
Common Confusion
Capias vs. bench warrant vs. arrest warrant: In contemporary usage, these terms are often used interchangeably, and statutes in many states have replaced capias with the plain phrase "bench warrant" or "arrest warrant." In historical common law sources, however, capias was a term of art with a specific procedural identity distinct from a general executive warrant of arrest. Conflating them creates errors when reading historical pleading records. Additionally, researchers should not confuse capias ad respondendum (civil pretrial arrest) with capias ad satisfaciendum (post-judgment body execution) — the procedural posture and applicable rules differed substantially.
Recognized Forms
/SUBTYPES
- Capias ad respondendum (ca. resp.): Pretrial arrest to compel appearance and answer.
- Capias ad satisfaciendum (ca. sa.): Post-judgment arrest to compel satisfaction of a civil judgment.
- Capias ad computandum: Arrest to compel rendering of an account.
- Capias pro fine: Arrest for failure to pay a court-imposed fine.
- Capias utlagatum: Writ to arrest an outlaw.
- Bench warrant / capias (modern): Judicial arrest order, typically on failure to appear.
Why It Matters in Research
Researchers face three distinct challenges with capias in the Law Mind corpus.
First, the term is a moving target across time. In the early common law corpus, capias appears as a technical pleading term with precise procedural meaning that depends on knowing which variant is at issue. In 19th-century American sources, the civil uses began to erode as debtor's prison reforms dismantled the capias ad satisfaciendum in most states. By the mid-20th century, the term had largely retreated to criminal courts. An entry reading "capias issued" in an 1820 case record means something procedurally different from the same phrase in a 1980 criminal docket.
Second, the collapse of debtor's prison practice is a major discontinuity. Sources in the Law Mind corpus from before roughly 1850 will discuss capias ad satisfaciendum as a live and commonly used writ. Later sources treat it as historical or abolished. Researchers working across this divide must not assume continuity.
Third, Latin abbreviations (ca. resp., ca. sa.) appear in older docket books and pleading records without explanation. Researchers encountering these abbreviations need to resolve which writ is meant before interpreting the procedural posture of the case.
The Rapalje & Lawrence entry in the source material above is anomalous — it appears to contain a misfiled definition relating to ecclesiastical law and the cape magnum, which is unrelated to capias. This reflects an indexing or transcription error in that source and should not be relied upon for capias research.
Historical Dictionary Support
Black's and Burrill's converge on the core definition: a writ commanding the officer to take the body of the defendant, named from the Latin imperative "capias" (that you take). Burrill adds the helpful specificity that the writ commanded the sheriff directly — "Præcipimus tibi quod capias" — illustrating the writ's form when proceedings were conducted in Latin. Black's notes the writ's survival in English criminal practice for indicted persons not yet in custody.
Both sources agree that capias ad respondendum and capias ad satisfaciendum are the two principal variants, with the latter representing the more severe post-judgment form. Neither source fully captures the 19th-century American reform context in which body execution on civil judgments was progressively abolished, leaving capias as primarily a criminal instrument. Anderson's adds nothing substantive beyond a cross-reference. Rapalje & Lawrence, as noted, contains a transcription error and should be set aside for this term.
Historical dictionaries as a class underemphasize how thoroughly the civil capias variants were dismantled by American legislative reform. Researchers relying solely on dictionary definitions will not appreciate how rapidly the writ's practical scope contracted after the 1830s.
Jurisdictional Note
Abolition of civil body execution proceeded at different rates across American states, so the capias ad satisfaciendum remained viable longer in some jurisdictions than others. In criminal practice, several states — including Texas, Florida, and Pennsylvania — retained the term capias in their modern codes and rules of criminal procedure, while other states replaced it with bench warrant or failure-to-appear warrant language. Research in any specific jurisdiction requires checking local statutes and rules to determine which terminology governs.
