Definition
Good behavior refers to conduct that conforms to law and the reasonable standards of a peaceable, law-abiding citizen. The term carries distinct legal weight in two principal contexts:
1. CRIMINAL LAW / SURETY: A court's power to require a person to enter into a recognizance — essentially a formal pledge, often backed by a monetary bond — guaranteeing that the person will behave lawfully for a defined period. This is distinct from a peace bond, though the two are closely related. A surety of good behavior can be demanded not only from persons who have committed an offense but from those who give reasonable grounds to suspect a criminal intention. Forfeiture of the recognizance is triggered by any breach of lawful conduct, making the standard broader and more easily violated than the narrower surety of the peace.
2. CONSTITUTIONAL / PUBLIC OFFICE: "Good behavior" is the tenure standard established in Article III of the U.S. Constitution for federal judges, who hold their offices "during good Behaviour." As a term of art in this context, it effectively means life tenure subject only to removal through the impeachment process. The standard is not self-executing through ordinary courts; it operates as a constitutional limit on congressional removal power, not as an independently litigable claim by a judge.
3. CORRECTIONS / SENTENCING: In modern criminal sentencing, "good behavior" or "good time" refers to conduct credits earned by incarcerated persons that reduce the actual time served. An inmate who follows institutional rules and avoids disciplinary infractions earns good-time credits at a statutory rate, shortening their custodial term. This usage is largely a creature of statute and varies substantially by jurisdiction.

Common Language
Modern common usage (Wiktionary): Conduct that is orderly, proper, and in keeping with social or institutional expectations; behavior meeting an expected standard.
Historical common usage (Webster's 1913): Orderly and proper conduct; decorous behavior.
The common-language sense captures the spirit but misses the legal mechanics. In law, good behavior is not merely a general commendation — it is an operative standard that triggers legal consequences: recognizances are forfeited, tenure is conditioned, and sentence reductions are calculated. Whether a person has behaved "well" in the ordinary sense is irrelevant; what matters is whether their conduct departed from lawful behavior as defined by the applicable legal framework.

Common Confusion
Good behavior and the peace are related but distinct sureties. A surety of the peace is specifically directed at preventing violence or threats against a particular person. A surety of good behavior is broader: it requires conformity with law generally and reaches anticipated criminal conduct of any kind. Bouvier notes that the good behavior recognizance "is more easily forfeited" than a peace bond, meaning courts and researchers should not treat the two instruments as interchangeable. Historical sources sometimes blur this line, and nineteenth-century American practice inherited English common law distinctions that were inconsistently applied across states.
Separately, the corrections usage — good time credits — is sometimes loosely called "good behavior time" in colloquial and journalistic writing. This is a statutory sentencing mechanism, not a common law surety, and the two should not be conflated when reading older case law that uses the phrase.

Recognized Forms
/SUBTYPES
1. Surety of Good Behavior (Common Law / Criminal): Recognizance exacted from a person suspected of intended criminal conduct, requiring a pledge to behave lawfully for a fixed term.
2. Constitutional Good Behavior Tenure: Article III standard for federal judicial tenure; functions as practical life tenure removable only by impeachment.
3. Statutory Good Time / Good Behavior Credits: Sentence reduction credits earned through compliant institutional conduct; a creature of modern corrections statutes.

Why It Matters in Research
Researchers working with pre-twentieth-century American and English sources will encounter "good behavior" almost exclusively in the surety context. The concept descends from English magistrates' practice codified in statutes of Edward III, carried into American common law, and discussed in Blackstone. Bouvier's reference to 1 Binn. 98 points to early Pennsylvania practice, a reminder that American reception of the surety doctrine was state-by-state and uneven.
The constitutional tenure usage appears in a structurally different literature — constitutional commentary, congressional debates over judicial independence, and scholarship on removal power — and rarely intersects with the criminal surety cases in historical compilations. Researchers who search a historical corpus for "good behavior" without filtering by context may retrieve materials from both streams and misread one for the other.
The corrections / good-time usage is almost entirely absent from pre-twentieth-century sources. Its rise tracks the development of the modern penitentiary and indeterminate sentencing, accelerating after the 1870s. Any nineteenth-century source using "good behavior" in a sentencing context deserves close reading to confirm which usage is intended.
The encyclopedia cross-reference above (Employment 4) is relevant to the narrower but growing context of good behavior clauses in employment contracts — particularly executive employment agreements that tie compensation, severance, or vesting to an employee's continued "good behavior" or absence of misconduct. This usage imports a quasi-legal standard into private contract, and courts have increasingly been called upon to define what constitutes a breach. Researchers in employment law should note that this contractual usage is distinct from all three of the primary legal usages and is typically governed by the specific contract language, not common law surety doctrine.

Historical Dictionary Support
Black's and Bouvier's agree on the core criminal law definition: good behavior is lawful conduct, and the surety mechanism is its primary enforcement vehicle. Both sources anchor the concept in the magistrates' power to exact recognizances from persons reasonably suspected of criminal intent — a preventive rather than punitive function.
Bouvier adds the important practical note that the good behavior recognizance is more easily forfeited than a surety of the peace and should therefore "be demanded with greater caution" — a caveat Black's omits. This asymmetry matters: Bouvier's formulation acknowledges that the broader standard creates a correspondingly higher risk of wrongful or abusive application. The cited authorities (1 Binn. 98, 14 Viner's Abridgment, Dane's Abridgment) reflect the early American and English common law pedigree of the doctrine.
What both historical sources miss almost entirely is the constitutional tenure dimension — understandable given their primary criminal law focus — and the modern corrections usage, which postdates both works' most influential editions. Researchers using these dictionaries as primary guides should supplement them with constitutional commentary and modern sentencing scholarship for the full picture.

Jurisdictional Note
The surety of good behavior is recognized at common law across American jurisdictions but has been substantially codified, modified, or displaced by statute in many states. The constitutional good behavior standard applies only to Article III federal judges; state judicial tenure is governed by individual state constitutions, which vary widely. Good-time credit statutes are entirely jurisdiction-specific and differ sharply in accrual rates, eligibility, and forfeiture rules.
