Definition
A Latin phrase meaning "for good behavior." In legal usage, de bono gestu describes the condition or standard imposed upon a person who is required to conduct themselves peaceably and lawfully — most commonly as a term of a recognizance, surety bond, or judicial order. A person bound de bono gestu undertakes, typically through a surety arrangement, to maintain good behavior for a specified period, with forfeiture of the bond or recognizance as the consequence of breach.
The phrase is closely associated with the judicial practice of requiring a bond or surety "for good behavior" (also called good abearance), distinct from — though easily confused with — a surety or bond to keep the peace. Where a peace bond responds to a specific threat of violence or disturbance, a de bono gestu obligation imposes the broader requirement of general lawful conduct.
Common Confusion
De bono gestu is frequently treated as interchangeable with surety of the peace (securitatem pacis), but the two carried distinct scope in common law practice. Surety of the peace was directed at preventing a specific anticipated breach — threats, affrays, or fear of bodily harm — and expired when that particular danger passed. De bono gestu, or good behavior, was a broader condition: it encompassed peaceful conduct generally and extended to offenses against public order beyond mere threatened violence. A magistrate could bind a person to good behavior on grounds that would not support a peace bond. The distinction matters in historical sources, where the two terms sometimes appear together and sometimes as alternatives, depending on the nature of the complaint and the court.
Why It Matters in Research
This term appears almost exclusively in older common law sources — treatises on magistrates' powers, forms books, and early criminal procedure materials — and has largely disappeared from modern American legal vocabulary as a technical term of art, absorbed into contemporary language about probation conditions, recognizance, and supervised release. Researchers working in historical corpus materials should watch for the phrase in contexts involving justices of the peace, quarter sessions proceedings, and recognizance records, where it describes the operative standard of a bond rather than a separate legal proceeding.
A key navigational point: de bono gestu will not appear in most modern statutory indexes or digests, but its functional descendants — conditions of release, good behavior bonds, and conduct requirements in probation orders — are well documented under those modern headings. When tracing the lineage of modern probation or conditional release concepts, de bono gestu sources provide essential historical foundation.
The phrase also appears in connection with certiorari and habeas corpus proceedings in historical reports, where courts reviewed whether the original commitment on a good behavior bond was lawfully issued. Researchers should not assume that a historical source's silence on the term means the practice was absent — it may simply have been described as "good abearance" or "security for behavior" by the same court in the same period.
Historical Dictionary Support
Black's Law Dictionary (both editions) defines the phrase tersely as "for good behavior; for good abearance," without elaboration on its procedural context or the distinction from surety of the peace. Burrill's Law Dictionary matches this definition — "for good behaviour" — and similarly offers no extended treatment. Neither source develops the substantive law behind the phrase, which is characteristic of short-form Latin phrase entries in nineteenth-century law dictionaries generally.
The brevity of these entries reflects the term's function: it is a phrase of legal shorthand rather than an independent cause of action or doctrine. Its full meaning is carried not by the phrase itself but by the body of common law governing recognizances and magistrates' authority to bind persons to good behavior — material found in treatises such as Dalton's The Countrey Justice and Hawkins's Pleas of the Crown rather than in dictionary entries.
No historical dictionary source consulted provides the distinction between de bono gestu and securitatem pacis, which must be sourced from treatise literature and case materials.
Jurisdictional Note
The concept of good behavior bonds grounded in de bono gestu authority was part of English common law received across American jurisdictions, but its explicit invocation by Latin phrase was largely confined to colonial and early republic practice. Modern American courts achieve the same functional result through statutory probation conditions and bail terms without using the Latin phrase.
