Definition
A preventive legal mechanism by which a person suspected of posing a future threat to public order is required to provide formal assurance — typically through pledges, bonds, or sureties — that no breach of the peace will occur. Unlike criminal punishment, which responds to a completed offense, surety of the peace operates prospectively: its object is prevention, not penalty.
The proceeding is initiated upon a showing of probable grounds to believe that a person intends or is likely to engage in conduct threatening public safety or order. Once such grounds are established, the subject may be required to enter into a recognizance — a formal acknowledgment of obligation before a magistrate or court — with or without co-signers, conditioned on keeping the peace for a specified period. Failure to provide the required security may result in commitment until the condition is satisfied.
Surety of the peace is distinct from surety for good behavior, though the two are closely related and often discussed together. Surety of the peace is the narrower form, directed specifically at preventing violence or immediate threats to persons; surety for good behavior is broader, covering general future misconduct.

Common Confusion
SURETY OF THE PEACE vs. SURETY FOR GOOD BEHAVIOR: These terms appear together throughout historical sources and are sometimes used interchangeably, but they carry distinct meanings. Surety of the peace addresses specific, apprehended threats of violence or breach of public order. Surety for good behavior (also called surety for good abearing) extends to a wider range of anticipated misconduct and applies in circumstances where the threat is less immediate or less specifically violent. Researchers encountering either term in historical records should examine context carefully before treating the two as synonymous.
SURETY OF THE PEACE vs. MODERN SURETYSHIP: The word "surety" in this term has no operative connection to the commercial suretyship of contracts and bond law — the three-party guarantee relationship between surety, principal, and obligee. The two concepts share only a word. In surety of the peace, the "surety" refers to security pledged to the public, not a guarantor of another party's debt or performance.

Why It Matters in Research
Surety of the peace is a common-law relic with deep roots in English magistrate practice, and its traces appear throughout historical American legal records — court minutes, recognizance books, justice of the peace dockets, and colonial statutes — in ways that modern researchers may not immediately recognize.
Several research traps are worth flagging:
Historical sources use the term inconsistently. Blackstone, Hawkins, and early American treatise writers distinguish surety of the peace from surety for good behavior with varying degrees of precision. When reading older secondary sources, do not assume the distinction is being maintained.
The mechanism has modern successors. Many jurisdictions have replaced or supplemented the common-law surety of the peace with statutory frameworks — harassment injunctions, peace bonds, civil restraining orders, and firearms surrender provisions. A researcher tracing the history of preventive civil restraint will find surety of the peace as the historical antecedent to these modern instruments.
Corpus connections are non-obvious. Because this term sits at the intersection of criminal law, civil procedure, and public order regulation, it may appear in encyclopedia entries and primary sources organized under any of those headings. Researchers should not limit searches to criminal law materials.
The recognizance as a companion instrument is essential. Surety of the peace is rarely documented as a standalone term in historical court records; look instead for the recognizance to keep the peace, which is the formal record of the obligation imposed.

Historical Dictionary Support
Black's Law Dictionary defines surety of the peace as "a species of preventive justice," citing Brown, and describes its operation accurately: probable grounds of apprehended future misbehavior trigger an obligation to provide pledges or security for keeping the peace or good behavior. This definition tracks the classical English common-law formulation closely.
The definition's attribution to "Brown" (likely Brown's Law Dictionary or a similar 19th-century digest) signals that Black's is here functioning as a conduit for received English common-law doctrine rather than synthesizing American statutory development. This matters because by the time of Black's early editions, American jurisdictions had already begun diverging from the English model through statute. The dictionary definition reflects doctrine more than practice as it actually existed in late 19th-century American courts.
What historical dictionaries largely omit: the procedural mechanics of how surety of the peace was actually invoked — who had standing to complain, what quantum of evidence satisfied the probable grounds requirement, and what commitment meant in practice. These questions were answered in treatises and in local practice, not in dictionary definitions. Researchers needing operational detail should consult Blackstone's Commentaries (Book IV), Hawkins' Pleas of the Crown, and early American magistrate's guides.

Jurisdictional Note
Surety of the peace as a common-law proceeding has been substantially absorbed, modified, or replaced by statute in most American jurisdictions. Some states retain a version under the label "peace bond" or "good behavior bond." The procedural threshold, duration, and consequences for default vary considerably. Researchers working with a specific jurisdiction should identify whether a statutory successor exists before treating the common-law doctrine as operative.

Encyclopedia Cross-Reference
Disorderly Conduct and Breach of Peace — The Law Mind Criminal Law Encyclopedia (criminal_107): Direct subject-matter connection; breach of peace is the threat that surety of the peace is designed to prevent.
Suretyship — Rights of the Surety (The Law Mind Contracts & Commercial Law Encyclopedia) (contracts_163): Relevant only to clarify the distinction; the commercial suretyship doctrine is separate from surety of the peace. Consult to understand what this term does not mean.
