Definition
A restraining order is a court order directing a person, entity, or in some contexts a subordinate tribunal, to refrain from a specific action or course of conduct. The term covers two distinct applications that share a common mechanism — judicial compulsion to abstain — but differ substantially in context, procedure, and purpose.
1. Injunctive context (private civil litigation). A restraining order is a judicial directive prohibiting a party from taking a threatened or ongoing action that would cause harm before the court can hear the matter fully. In this sense it functions as a preliminary tool within the broader family of injunctive relief. The most familiar subtype is the temporary restraining order (TRO), issued ex parte or on short notice to preserve the status quo pending a hearing on a preliminary injunction. The TRO is by nature short-lived and provisional; its purpose is to prevent irreparable harm in the gap between the filing of a complaint and the first meaningful opportunity for both parties to be heard.
2. Domestic and protective context (family law and criminal proceedings). A restraining order in this usage is a court order prohibiting one person from contacting, approaching, or harassing another — most commonly issued in response to allegations of domestic violence, stalking, or harassment. These orders are also called protective orders and may be issued by civil family courts or by criminal courts as a condition of bail, probation, or sentencing. They frequently include geographic restrictions (stay-away provisions), prohibitions on contact through third parties, and firearm surrender requirements.
A third, older usage appears in equity practice: courts of superior jurisdiction historically issued restraining orders directed at inferior courts or tribunals to halt proceedings exceeding their jurisdiction. This overlaps substantially with the writ of prohibition but was sometimes distinguished as a less formal mechanism. This usage is rare in modern practice.

Common Language
Modern common usage (Wiktionary): A restraining order is understood as a court order forbidding a person from doing something — particularly approaching or contacting another person.
Historical common usage (Webster's 1913): Webster's 1913 does not contain a discrete entry for "restraining order" as a compound term. "Restrain" is defined generally as to hold back, limit, or keep within bounds.
The common understanding tracks the domestic/protective meaning closely. The significant gap is between popular usage and the injunctive-litigation meaning: lay speakers rarely associate "restraining order" with commercial disputes, property rights, or corporate litigation — contexts where TROs are routine and consequential. A researcher encountering "restraining order" in a business litigation file should not assume a domestic violence context.

Common Confusion
Restraining order, preliminary injunction, and temporary restraining order are frequently conflated. They are related but distinct: a TRO is the most urgent and short-term measure, typically ex parte and limited in duration by rule. A preliminary injunction requires notice to the opposing party and a hearing, and lasts until a final ruling. A permanent injunction is the ultimate remedy after a full adjudication on the merits. "Restraining order" is sometimes used loosely to mean any of these; precision matters in research because procedural rules, standards of proof, and appellate rights differ across the three.
In the domestic violence context, restraining order and protective order are used interchangeably in common speech and in many statutes, but some jurisdictions reserve one term for civil proceedings and the other for criminal. The functional content may be identical; the issuing court and enforcement mechanism may not be.

Recognized Forms
/SUBTYPES
Temporary Restraining Order (TRO): Short-duration, often ex parte order preserving the status quo pending an injunction hearing. Subject to strict durational limits under court rules.
Preliminary Injunction: Issued after notice and hearing; maintains the status quo through trial. Requires the moving party to demonstrate likelihood of success on the merits, risk of irreparable harm, balance of hardships, and public interest.
Emergency Protective Order (EPO): Issued by law enforcement officers or courts in domestic violence emergencies, sometimes by telephone, effective for a very short period until a formal hearing can be scheduled.
Domestic Violence Restraining Order / Civil Protective Order: Issued by a civil or family court on petition of the protected party. Typically longer in duration and enforceable by contempt or criminal sanction on violation.
Criminal Protective Order: Issued in a criminal proceeding as a condition of bail, probation, or sentence. Runs concurrent with criminal case and may extend beyond it.

Why It Matters in Research
The term "restraining order" is not stable across time, jurisdiction, or legal context. A researcher must determine which meaning is operative before reading any source that uses the term without qualification.
Historical sources are particularly unreliable on the domestic violence subtype. Before the 1970s, the modern protective order framework for domestic violence victims did not exist in most U.S. jurisdictions. When historical cases or treatises mention "restraining orders," they almost always mean injunctive relief in civil litigation or the equity-court mechanism directed at inferior tribunals — not the family law protection order that dominates contemporary legal conversation. Reading backward from modern assumptions will distort the analysis.
The injunctive-context TRO is governed by procedural rules (Federal Rule of Civil Procedure 65 at the federal level; analogous state rules) that set duration, notice requirements, and bond conditions. These rules have evolved, and their content is essential context when reading decisions about TROs issued under earlier versions. The bond requirement in particular has significant case law of its own.
In the domestic violence context, federal law intersects through the Violence Against Women Act and 18 U.S.C. § 2265, which requires full faith and credit recognition of qualifying protective orders across state and tribal lines. This federal layer is entirely absent from historical sources and from any secondary authority predating the 1990s.
The "restraining inferior courts" usage connects to prohibition jurisprudence and is searchable in equity treatises under prohibition, certiorari, and supervisory jurisdiction — not necessarily under "restraining order" as a heading. Researchers pursuing this angle should consult the Remedies & Equity Encyclopedia entry on prohibition directly.
For corpus researchers: case law databases may return mixed results when querying "restraining order" — blending domestic violence appeals, commercial TRO disputes, and older equity cases. Filtering by court type, time period, and subject-matter classification will be necessary before any quantitative or qualitative analysis is reliable.

Historical Dictionary Support
Rapalje & Lawrence define a restraining order as an order in equity restraining the defendant from doing some act injurious to the plaintiff until the hearing of the application for an injunction. This definition firmly situates the term within civil equity practice and treats the restraining order as a preliminary or provisional measure — a holding device pending fuller judicial examination. The Rapalje & Lawrence formulation does not contemplate the domestic violence protective order context, which is unsurprising given the era of the dictionary.
What Rapalje & Lawrence capture accurately is the functional logic that carries across all uses of the term: a court ordering restraint of action to prevent harm before a more complete proceeding resolves the underlying dispute or threat. That logic is the conceptual through-line, even as the specific applications have multiplied.
What historical dictionaries uniformly miss: the entire domestic violence protective order framework, the federal full-faith-and-credit dimension, the firearm prohibition component now embedded in many such orders, and the role of law enforcement in the EPO process. Any research that relies heavily on historical secondary sources for the domestic violence meaning of the term will have a significant blind spot.

Jurisdictional Note
Terminology and procedure vary substantially by state. Some jurisdictions call the civil family-court instrument a "protective order" and reserve "restraining order" for injunctive relief in general civil litigation; others use the terms interchangeably in statute and court rule. Duration, renewal procedures, and enforcement mechanisms — including whether violation is a civil contempt or a standalone criminal offense — differ by jurisdiction. Federal courts apply Rule 65 for injunctive restraining orders but may also issue protective orders in criminal matters under separate authority.
