Definition
A mutual assent between two or more parties to a common purpose, creating, modifying, or extinguishing rights and obligations between them. An agreement requires a meeting of minds — each party must consent to the same thing in the same sense. Agreement is the broader genus of which contract is the principal species. Not every agreement is legally enforceable; enforceability depends on the presence of additional elements, chiefly consideration and legal capacity. An agreement may also describe informal understandings, partially formed arrangements, or transactions in which mutual assent exists but formality or enforceability is incomplete or in question. In practice, the term carries at least three working senses: 1. Generic assent: Any concordance of understanding between parties, whether or not enforceable — the broadest meaning, used loosely in both legal and ordinary speech. 2. Enforceable contract: When all elements of contract formation are present, "agreement" and "contract" are often used interchangeably, though technically contract is the legal obligation arising from the agreement. 3. Written instrument: A document memorializing the terms of a transaction, such as a purchase agreement, shareholders' agreement, or settlement agreement. The instrument is evidence of the agreement, not the agreement itself.
Common Language
Modern common usage (Wiktionary): "An understanding between entities to follow a specific course of conduct"; also, more broadly, "a state whereby several parties share a view or opinion." Historical common usage (Webster's 1913): "State of agreeing; harmony of opinion, statement, action, or character; concurrence; concord; conformity." The gap that matters for researchers: In ordinary usage, agreement denotes any shared view or understanding — including informal, social, or non-binding ones. In law, the term narrows toward mutual assent with legal consequences. The common meaning captures the concept; the legal meaning demands precision about what type of agreement exists and whether it binds. A source describing an "agreement" in a historical document may mean anything from a binding contract to a handshake understanding, and researchers should not assume enforceability from the word alone.
Common Confusion
Agreement vs. Contract: The historical dictionaries themselves blur this line, and modern usage compounds the problem. The traditional distinction — agreement is the mutual assent; contract is the legally enforceable obligation arising from it — is real but routinely ignored in practice. Statutes, instruments, and courts frequently use the terms interchangeably. When precision matters (e.g., in analyzing formation disputes or the enforceability of oral arrangements), the distinction is essential. Agreement is the broader term; contract is agreement plus enforceability. Agreement vs. Promise: A promise is unilateral — one party's commitment. An agreement is bilateral or multilateral — a conjunction of promises or performances. Confusing the two distorts analysis of offer and acceptance, particularly in historical sources that sometimes treat "agreement" as encompassing a single binding promise.
Core Elements
The historical sources, particularly Bouvier and Burrill, converge on three foundational requirements for an agreement to have legal significance: 1. Mutual assent (aggregatio mentium): Two or more minds must unite on the same subject matter and terms. This is the core. Without it, there is no agreement in any legal sense. 2. Certainty and completeness: Bouvier's formulation — that the agreement "ought to be so certain and complete that either party may have an action on it" — reflects the enforceability threshold. Vague or illusory terms defeat the agreement at formation. 3. Quid pro quo: Bouvier links enforceability to consideration. This is the agreement-to-contract bridge. Where the quid pro quo is absent, the agreement may exist as a moral or social matter but not as a legal one.
Why It Matters in Research
Agreement is one of the most heavily used terms in the legal corpus, and its very ubiquity is a research hazard. The word appears in nearly every transactional, constitutional, and procedural context, which means corpus searches for "agreement" will return results across wildly different legal categories — tax closing agreements, shareholder voting arrangements, plea agreements, treaty instruments, arbitration clauses, and informal settlement terms all travel under this label. Three traps for historical researchers: First, the agreement/contract distinction was more rigorously maintained in 18th- and 19th-century sources than in modern ones. Older texts that distinguish between an "agreement" and a "contract" or "specialty" are making a deliberate doctrinal point about enforceability, not being redundant. Do not flatten that distinction when reading period materials. Second, the Statute of Frauds (and its American descendants) cuts across agreement doctrine in ways that historical sources handle inconsistently. An agreement that is valid and binding at common law may nonetheless be unenforceable for want of a writing. Historical dictionary entries often note this; researchers should check whether the source's discussion of agreement accounts for the Frauds dimension. Third, in the tax and business organization contexts specifically, "agreement" has acquired specialized procedural and regulatory meanings — IRS installment agreements and closing agreements are creatures of statute and administrative practice, not common-law contract doctrine, and should be researched through those frameworks rather than general agreement doctrine. For corpus navigation: agreement terms cluster around contract formation, settlement and ADR materials, corporate governance instruments, and international law. When researching a specific instrument type, use the instrument's name ("shareholders' agreement," "closing agreement") rather than bare "agreement" to control search results.
Historical Dictionary Support
The major historical dictionaries are substantially in agreement (appropriately) on the core concept. Black's (both editions), Bouvier's, and Burrill's all converge on the aggregatio mentium formulation — the union of two or more minds — as the definitional heart of the term. The phrasing "coming together of parties in opinion or determination" appears verbatim or near-verbatim across all three, suggesting a shared common-law lineage for the definition rather than independent derivation. Bouvier's is the most analytically rigorous of the historical sources on this term. Its insistence on certainty, completeness, and quid pro quo as conditions for actionability moves the definition beyond mere conceptual description toward doctrinal substance. Burrill adds texture by tracking the Latin and Law Latin antecedents (conventio, pactum, agreamentum), which is useful when reading sources that use those terms as near-synonyms. Rapalje & Lawrence is less useful here for the core definition — the relevant entry in the source material is fragmentary and trails into related phrases ("agree to let," "agree to sell") rather than developing the concept. These phrase-specific treatments are valuable when researching the interpretation of particular contractual language in historical cases, but they do not add to the foundational definition. What the historical dictionaries collectively underemphasize: the distinction between agreement as a concept and agreement as a written instrument. Modern practice has substantially shifted toward treating the signed document as "the agreement," a usage that would have struck the classical common lawyers as imprecise. Researchers reading 19th-century sources should not assume the written instrument usage dominates.

The act of two or more persons, who unite in expressing a mutual and common purpose, with the view of altering their rights and obligations. A coming together of parties in opinion or determination; the union of two or more minds in a thing done or to be done; a mut- ual assent to do a thing. Com. Dig. "Agree- ment," A 1. The consent of two or more persons con- curring, the one in parting with, the other in receiving, some property, right, or benefit. Bac. Abr. A promise, or undertaking. This is a loose and incorrect sense of the word. 5 East, 11. See 3 Brod. & B. 14; 3 N. Y. 335. The writing or instrument which is evi- dence of an agreement. Agreements are of the following several descriptions, viz.: Conditional agreements, the operation and effect of which depend upon the existence of a supposed state of facts, or the performance of a condition, or the happening of a contin- gency. Executed agreements, which have reference to past events, or which are at once closed and where nothing further remains to be done by the parties. Executory agreements are such as are to be performed in the future. They are commonly preliminary to other more formal or important contracts or deeds, and are usually evidenced by memoranda, parol promises, etc. Express agreements are those in which the terms and stipulations are specifically de- clared and avowed by the parties at the time of making the agreement.

A coming together of parties in opinion or determination; the union of two or more minds in a thing done or to be done; a mutual assent to do a thing. Comyn, Dig. Agreement, A1; Plowd. 5a, 6 a. Aggregatio mentium.-When two or more minds are united in a thing done or to be done. It ought to be so certain and complete that either party may have an action on it, and there must be a quid pro quo; Dane, Abr. c. 11. The consent of two or more persons con- curring, the one in parting with, the other in receiving, some property, right, or bene- fit; Bacon, Abr. An act in the law where- by two or more persons declare their assent as to any act or thing to be done or forborne by some or one of those persons for the use of the others or other of them. Poll. Contr. 2. "The expression by two or more persons of a common intention to affect the legal relations of those persons; " Anson, Contr. 8. An agreement "consists of two persons being of the same mind, intention, or mean- ing concerning the matter agreed upon;" Leake, Contr. 12. See Poll. Contr. 2, 3. "Agreement" is seldom applied to specialties; "contract" is generally confined to simple con- tracts; and "promise" refers to the engagement of & party without reference to the reasons or consid- erations for it, or the duties of other parties; Pars. Contr. 6. An agreement ceases to be such by being put in writing under seal, but not when put in writing for a memorandum; Dane, Abr. c. 11. It is a wider term than "contract;" Anson, Contr. 4; an agreement might not be a contract, because not fulfilling some requirement of the law of the place in which it is made. A promise or undertaking. This is the loose and inaccurate use of the word; 5 East 10; 8 B. & Β. 14; 8 Ν. Υ. 835. The writing or instrument which is evi- dence of an agreement. This is a loose and evidently inaccurate use of the term. The agreement may be valid, and yet the written evidence thereof insufficient; as, if a pro- missory note be given for twenty dollars, the amount of a previous debt, where the note may gen- erally be neglected an lected and the debt collected by means of other evidence; or, again, if a note good in form be given for an illegal consideration, in which case the instrument is good and the agreement void. Conditional dgreements are those which are to have full effect only in case of the happening of certain events, or the exist- ence of a given state of things. Executed agreements are those where nothing further remains to be done by the parties. Executed agreements take place when two or more persons make over their respect- ive rights in a thing to one another, and thereby change their property therein either presently and at once, or at a future time upon some event that shall give it full effect without either party trusting to the other. Such an agreement exists where a thing is bought, paid for, and delivered. Executory agreements are such as rest on articles, memorandums, parol promises or undertakings, and the like, to be performed in the future, or which are entered into pre- paratory to more solemn and formal aliena- tions of property; Powell, Contr. An executed agreement always conveys a chose in possession, while an executory one conveys a chose in action only. Express agreements are those in which the terms are openly uttered and avowed by the parties at the time of making. Implied agreements are those which the law supposes the parties to have made al- though the terms were not openly expressed. Thus, every one who undertakes any office, em ployment, or duty impliedly contracts to do it with Integrity, diligence, and skill; and he impliedly con tracta to do whatever is fairly within the scope of his employment; 6 Scott 761. Implied promises, or promises in law, only exist where there is no express stipulation between the parties touching the same matter for expressum facit cessare tacitum: 2 Bla. Com. 444: 2 Term 105; 7 Scott 60; 1 N. & P. 633. The parties must agree or assent. There must be a definite promise by one party accepted by the other; 3 Johns. 534; 12 id. 190;9 Ala. 69: 29 Ala. N. s. 864; 4 R. I. 14: 2 Dutch. 268; 3 Halst. 147; 29 Pa. 358; 49 Ill. App. 141. There must be a commun- ication of assent by the party accepting; a mere mental assent to the terms in his own mind is not enough; L. R. 2 App. Ca. 691. See 102 Mo. 309. But the assent need not be formally made; it can be inferred from the party's acts; L. R. 6 Q. B. 607; L. R. 10 C. P. 307; 90 Ala. 529. They must assent to the same thing in the same sense; 4 Wheat. 225; 1 Sumn. 218; 2 Woodb. & M. 359; 7 Johns. 240; 18 Ala. 605; 9 M. & W. 535; 4 Bing. 660; L. R. 6 Q. B. 597. The assent must be mutual and obligatory; there must be a request on one side, and an assent on the other; 5 Bingh. N. C. 75; 150 Mass. 248. Where there is a misunderstand- ing as to the date of performance there is no contract, for want of mutual assent; 42 La. Ann. 107; or where there is a misunder- standing as to the manner of payment;
