Definition

Restraint, in law, refers to the limitation, confinement, or prohibition of action — whether applied to persons, property, speech, or commercial activity. Because the word spans so many doctrinal contexts, researchers must identify which domain is controlling before interpreting the term. The principal legal meanings are:

RESTRAINT OF PERSON. Any act or condition that limits, confines, or withholds a person's freedom of movement or physical liberty. In criminal and tort law, unlawful restraint of a person is a foundational element of false imprisonment and, in aggravated forms, kidnapping. The restraint need not be physical; threats, coercion, or legal process can accomplish it.

RESTRAINT OF TRADE. A limitation on commercial activity or free competition, whether by contract, combination, or monopolistic conduct. At common law, contracts in restraint of trade were generally void as against public policy, though courts developed the "reasonable restraint" doctrine to salvage covenants ancillary to legitimate business transactions — such as non-compete clauses in employment or sale-of-business agreements.

RESTRAINT ON ALIENATION. A limitation on a property owner's ability to transfer, sell, or encumber property. Absolute restraints on alienation of fee simple interests are void as contrary to public policy and the productive use of land. Partial restraints — as in spendthrift trust provisions — receive more nuanced treatment.

RESTRAINT OF MARRIAGE. A condition or covenant purporting to prohibit or substantially discourage marriage. General restraints on marriage are void as against public policy; partial or limited restraints (e.g., until a certain age, or against marriage to a specific person for specific articulable reasons) may be enforceable depending on jurisdiction and context.

PRIOR RESTRAINT. In constitutional law, government action that prohibits speech or publication before it occurs, as distinguished from punishment after the fact. Prior restraints carry a heavy presumption of unconstitutionality under First Amendment doctrine.

DURESS AND INVOLUNTARY EXECUTION. A deed, contract, or other instrument executed under restraint — meaning under compulsion or coercion — may be voidable on grounds of duress. Here "restraint" signals not a legal category but a factual condition affecting consent.

Common Language

Modern common usage (Wiktionary): Something that restrains, ties, fastens, or secures; control or caution; reserve.

Historical common usage (Webster's 1913): The act or process of holding back or hindering from motion or action in any manner; hindrance of the will, or of any action, physical or mental; also, that which restrains, as a law or prohibition.

The gap between common and legal usage is less one of meaning than of precision. In ordinary English, restraint is a single, unified concept. In law, the same word operates as a term of art in at least five distinct doctrinal domains — each with its own rules, tests, and consequences. A researcher who approaches a historical source using "restraint" without first fixing the subject-matter context risks reading a commercial-law discussion as if it were a personal-liberty analysis, or vice versa.

Common Confusion

RESTRAINT vs. RESTRICTION. These words are often used interchangeably in older texts, but modern doctrine sometimes distinguishes them: a restriction narrows the permissible uses of property (e.g., a restrictive covenant limiting land to residential use), while a restraint on alienation goes further and limits the power to transfer. A restriction does not necessarily restrain alienation; a restraint on alienation is always a form of restriction. Conflating them in property research can distort analysis of enforceability rules.

RESTRAINT OF TRADE (common law) vs. ANTITRUST VIOLATION (statutory). Common law restraint of trade doctrine and modern antitrust law address overlapping concerns but follow different analytical frameworks, use different burdens, and produce different remedies. Historical materials — especially pre-Sherman Act sources — address only the common law doctrine. Do not read early restraint-of-trade authorities as if they applied antitrust standards.

Recognized Forms

/SUBTYPES

— Absolute restraint: Prohibits transfer or use entirely. Generally void as against public policy in property and trade contexts.
— Reasonable (partial) restraint: Limited in scope, duration, and geography; may be enforceable, particularly in trade and employment contexts.
— Restraint on anticipation: Historically, a device used in trusts to protect a married woman's equitable property from her husband's creditors by preventing her from anticipating or charging future income. Largely abolished by statute in most jurisdictions.
— Spendthrift restraint: A trust provision preventing a beneficiary from voluntarily alienating or involuntarily assigning their interest. Treated as a recognized exception to the general policy against restraints on alienation.
— Prior restraint: The government's use of law or judicial order to suppress speech before it is expressed. Subject to heightened constitutional scrutiny.

Why It Matters in Research

The principal research trap with "restraint" is doctrinal drift across sources. Bouvier's organizes the term around four subject-matter categories (trade, marriage, princes, alienation) that do not map cleanly onto modern doctrinal groupings. Researchers using Bouvier's for property or trade research will find those threads, but constitutional dimensions of speech restraint are essentially absent from nineteenth-century dictionary treatment — that framework developed later. Black's first and second editions give only a general liberty-of-person definition with no systematic treatment of the commercial or property senses; researchers who stop there will miss the most litigated modern applications.

In corpus searching, "restraint" appears in radically different doctrinal contexts with no internal signal about which is meant. Proximity searches pairing "restraint" with "trade," "alienation," "marriage," "prior," or "person" will substantially reduce noise. In historical commercial materials, "restraint of trade" was a common law term of art before it became associated with antitrust; the same phrase across different time periods signals different bodies of law.

The "reasonable restraint" doctrine in trade and non-compete law evolved dramatically between the mid-nineteenth century and the mid-twentieth. Early sources treated nearly all restraints on trade as void; later sources introduced the partial-restraint exception and ancillary covenant analysis. A historical source finding a restraint "void" may be applying the earlier, categorical rule rather than the modern balancing test.

Constitutional prior restraint doctrine is almost entirely a twentieth-century development. Any historical dictionary source that does not address it should not be read as evidence that prior restraints were unproblematic in earlier law — the doctrine was developing in case law while dictionaries lagged.

Restraint as a condition affecting consent (duress) overlaps with but is not coextensive with the tort and criminal-law senses. In deed and contract analysis, look for the duress treatment specifically, as Bouvier's cross-references.

Historical Dictionary Support

Black's (both editions) defines restraint at the level of generality: confinement, abridgment, limitation, prohibition of action. This captures the personal-liberty sense clearly but leaves the property and commercial senses unaddressed. The second edition's partial quotation — asking whether the limitation "must be imposed by those in possession of the person or thing" — hints at a contested definitional boundary in the personal-liberty context, though the passage is fragmentary.

Bouvier's is the most systematically useful of the historical sources for property and transactional research, organizing the entry around its practical applications: trade, marriage, alienation, and the special case of restraint upon anticipation (cross-referenced to Married Woman). Bouvier's also explicitly cross-references Duress for execution under restraint, which is a functionally important connection for deed and contract research. Bouvier's treatment is comprehensive for its era but predates both the development of antitrust law and constitutional prior restraint doctrine.

Rapalje & Lawrence's entry, as reproduced, appears to address restitutio in integrum — the Roman law principle of restoring a party to their original position — rather than "restraint" in the senses catalogued here. This may represent a source extraction artifact. Researchers should treat that entry with caution as applied to the English or American restraint doctrine.

Across the historical sources, there is consensus that restraints against public policy are void and that some partial or limited restraints are permissible — but none of the sources develops a unified framework. The reasonable-restraint test and the modern tiers of constitutional analysis are products of case law development that post-dates these dictionaries.

Jurisdictional Note

Non-compete and trade restraint enforceability varies sharply by state. California, for example, renders most post-employment non-compete agreements void by statute, while many other states apply a reasonableness balancing test. Restraints on alienation in trust instruments are governed by state property law, and the scope of recognized spendthrift protection differs across jurisdictions. Constitutional prior restraint doctrine applies federally through the First Amendment and is incorporated against the states, but state constitutional analogues may provide additional or different protections.

Black's Law Dictionary (2nd Ed.) • 1910

Confinement, abridgment, or limitation. Prohibition of action; holding or pressing back from action. Hindrance, confinement, or restriction of liberty. “What, then, according to a common unaer standing, is the meaning of the term ‘restraint? Does it imply that the limitation, restriction, or confinement must be imposed by those why are in possession of the person or thing which is limited, restricted, or confined, or is the term satisfied by a restriction created by the applica: tion of external force? If, for example, a town be besieged, and the inhabitants confined within its walls by the besieging army, if, in attempta come out, they are forced back, would it be inaccurate to say that they are restrained within those limits? The court believes that it would not; and, if it would not, then with equal propriety may it be said, when a port is blockaded, that the vessels within are confined, or restrained from coming out: The aaa passe force is not in possession of the vessels incl in the harbor, but it acts upon and restrains them. It is a vis major, applied directly and effectually to them, which prevents them from coming out of port. This appears to the court to be, in correct language, ‘a restraint,’ by the power imposing the blockade; and when a vessel, attempting to come out, is boarded and turned back, this restraining force is practically applied to such vessel.” Olivera v. Union Ins. Co., 3 Wheat. 189. 4 L. Ed. 365. The terms “restraint” and “detention of princes,” as used in policies of marine ran have the same meaning,—that of the effect o superior force, operating directly on the vessel. So long as a ehip is under restraint, so ead detain ‘she is detained; and, whenever she is she is under restraint. Richardson v. Insurance Co.. 6 Mass. 102, 4 Am. Dec. 92. —Restraint of marriage. <A contract, covenant, bond, or devise is “in restraint of marriage” when its conditions unreasonably names or restrict the parey freedom to m , or his choice, or unduly postpone the time of his mar riage—Restraint of trade. Contracts or combinations in restraint of trade are such as tend or are designed to eliminate or stifle competition, effect a monopoly, artificially maintain prices, or otherwise hamper or obstruct the course of trade and commerce as it would be carried on if left to the control of natural and economic forces. See U. S. v. Trans-Missouri rt a Ass'n, 106 U. S. 290, 17 Sup. Ct. 540, 41 L. . 1007; Hodge vy. Sloan, 107 N. Y. 244, 17 N. B. 385, 1 Am. St. Rep. 816. With reference to contracts between individuals, a restraint of trade is said to be “general” or "special.” <A contract which forbids a person tu employ his talents, industry, or capital in any undertaking within the limits of the state or country is in “general’* rertraint of trade; if it forbids him to employ himself in a designated trade or business, either for a limited time or within a prescribed area or district, it is in “special” restraint of trade. See Holbrook v. Waters, 9 How. Prac. (N. Y.) 337.—Restraint on alienation is where property is given to a married woman to her separate use, without power of alienation.

(1118) (see Dig. iii. 3, fr. 39, § 6; iv. 2 fr. 9,83), where it was applied to cases where a person who, according to strict law, had lost a right, was restored to his original position by the judgment of a court acting on equitable principles. (7 Sav. Syst. 91 et seq.; Thibaut Pand. 680.) In English and American law it is used to denote the equitable relief which is given in rescinding contracts on the ground of fraud, and in similar cases, where both parties can be restored to their original position.
