Definition
An affidavit to hold to bail is a sworn written statement submitted by a plaintiff or someone with personal knowledge of the facts to justify the arrest and detention of a defendant in a civil action until that defendant furnishes bail — that is, a financial guarantee of appearance or satisfaction of judgment. The affidavit operates as the threshold showing required before civil process in the form of an arrest could issue. It had to establish, clearly and with particularity, that a debt or legal obligation was owed from the defendant to the plaintiff and that a distinct, cognizable cause of action existed.
The affidavit is not a pleading and not a judgment. It is a procedural instrument: a gatekeeper document that a court or officer used to determine whether civil arrest was warranted at all.
Why It Matters in Research
This term is almost entirely historical in American practice. Researchers encountering it should understand that it belongs to an era when civil arrest — the detention of a debtor's person as a means of compelling payment or appearance — was a normal feature of common law civil procedure. That practice has been abolished or severely curtailed across virtually all U.S. jurisdictions, making the affidavit to hold to bail a dead letter in modern litigation.
In historical sources, particularly materials from the eighteenth and early nineteenth centuries, the affidavit to hold to bail appears frequently in treatises on pleading and practice. Researchers working with early American court records, colonial-era case files, or English common law materials should expect to encounter this instrument in connection with writs of capias ad respondendum — the process by which a defendant's body was seized to compel answer to a civil suit.
The critical research trap: do not conflate this with criminal bail or criminal arrest. The affidavit to hold to bail operated exclusively in civil proceedings. It was a private plaintiff's tool, not the state's. Cross-referencing this term with related civil arrest records requires attention to that distinction, because archival records may file civil and criminal arrest documents together without clear separation.
Researchers should also note that the evidentiary standard for the affidavit was meaningful but not demanding — it had to show a distinct cause of action and a specific debt, but it did not require proof sufficient for judgment. The practical effect was that plaintiffs could use the mechanism as leverage against defendants who might otherwise evade satisfaction of a future judgment by departing the jurisdiction.
Historical Dictionary Support
The three source dictionaries agree on the essential character of the term but vary in depth. Bouvier's provides the most substantive entry, requiring that the affidavit contain a statement "clearly and certainly expressed, by some one acquainted with the fact" — language tracking the precision courts expected. Bouvier also cross-references Selwyn's Nisi Prius and Chitty on Pleading, both standard practice manuals of the period, indicating this was a well-developed procedural doctrine rather than an occasional curiosity. Rapalje and Lawrence offer the concise functional definition: an affidavit made to procure the arrest of the defendant in a civil action. Black's entry, as excerpted, provides only a fragment but situates the term correctly in civil rather than criminal procedure.
What the historical dictionaries collectively leave unaddressed is the trajectory of abolition. By the time these dictionaries were compiled in their major nineteenth-century editions, American jurisdictions were already moving to restrict or eliminate civil arrest. Researchers should not assume that descriptions in these sources reflect the law in any given state at any given time — the procedural landscape was shifting, and the affidavit to hold to bail was losing ground as debtor protection legislation expanded.
Jurisdictional Note
Civil arrest as a procedure — and with it, the affidavit to hold to bail — was abolished across most U.S. states during the nineteenth and early twentieth centuries through a combination of constitutional provisions, debtor relief statutes, and procedural reform. England underwent similar reform through the Debtors Act 1869. Researchers working with pre-abolition materials should identify the specific jurisdiction's timeline for reform before drawing conclusions about how this instrument functioned in a given case.
