Definition

Dependent upon, or granted subject to, a condition. Something is conditional when its existence, enforceability, or effect turns on the occurrence or non-occurrence of a specified event or circumstance, rather than operating absolutely and immediately.

As a modifier, "conditional" attaches to a wide range of legal instruments and statuses:

Conditional promise or obligation: A promise or duty that becomes binding only upon the happening of a stated condition precedent, or that is subject to discharge upon the happening of a condition subsequent.

Conditional conveyance or bequest: A transfer of property — real or personal — that takes effect, is defeated, or is limited by the occurrence of a specified event. Conditional fees in land law are the historical ancestor of the fee tail.

Conditional acceptance: An acceptance that varies the terms of an offer; in contract law, generally treated as a counter-offer rather than a true acceptance.

Conditional creditor (civil law): A creditor holding a right of action in expectancy — that is, a future or contingent right, not yet matured into an enforceable present claim.

Conditional release or discharge: In criminal and administrative law, a release from custody, obligation, or penalty that continues subject to specified behavioral or legal requirements, revocable upon breach.

Common Language

Modern common usage (Wiktionary): Limited by a condition; true or operative only if another thing is true.

Historical common usage (Webster's 1913): Containing, implying, or depending on a condition; not absolute; made or granted on certain terms. Also used in logic and grammar to describe conditional propositions and modes.

The common and legal meanings align closely in their core sense — both describe something contingent rather than absolute. The legal significance lies in precision: legal usage demands that the condition be identified with specificity, and attaches distinct consequences to its classification (precedent vs. subsequent, express vs. implied, lawful vs. void as against public policy). The ordinary sense of "conditional" captures none of this structural weight.

Common Confusion

Conditional vs. contingent: These terms overlap but are not synonymous. "Contingent" typically describes an interest or right that may never vest because the condition triggering it may never occur. "Conditional" is broader — it encompasses conditions precedent (must occur for the right to arise), conditions subsequent (occurrence defeats an already-existing right), and conditions concurrent. All contingent interests are conditional in some sense, but not all conditional arrangements create contingent interests. Researchers conflating the two in historical deed and will instruments may misread the nature of the property interest conveyed.

Conditional acceptance vs. qualified acceptance: In bills of exchange and negotiable instruments law, these terms historically carried distinct technical meanings. A qualified acceptance altered the effect of the instrument in ways that a merely conditional acceptance did not. Modern UCC treatment has reshaped this distinction; historical sources should be read with care.

Recognized Forms

/SUBTYPES

Conditional creditor — Civil law concept of a creditor with a right in expectancy; not to be confused with a secured creditor or a contingent creditor in modern bankruptcy usage.

Conditional fee — A fee simple restrained to particular heirs, the historical precursor to the fee tail under English land law.

Conditional sale — A sale in which title remains in the seller until a condition (typically full payment) is met by the buyer; the ancestor of the modern security interest under Article 9 of the UCC.

Conditional stipulation — Civil law: a stipulation to perform upon the occurrence of a specified event.

Conditions of sale — In real property practice, the terms and restrictions announced or published in connection with a sale, particularly at auction; the term "condition" here operates closer to "stipulation" or "restriction" than to condition in the strict doctrinal sense.

Why It Matters in Research

"Conditional" is a modifier rather than a freestanding doctrine, so its research significance depends almost entirely on what noun it modifies. The term appears across contract, property, criminal, civil law, and procedural sources, and its meaning shifts materially depending on context.

In property research, the critical distinction is between conditions precedent and conditions subsequent in deeds and wills. A condition subsequent that is void (e.g., as a restraint on alienation or against public policy) may be struck while leaving the underlying grant intact, or may void the entire instrument — the outcome turns on jurisdiction and period. Researchers working with pre-20th-century deed language must be alert to the fact that "conditional fee," "fee upon condition," and "fee tail" were sometimes used interchangeably in practice even when technically distinct.

In commercial and contracts research, "conditional sale" is a term that migrated substantially in meaning. Pre-UCC, conditional sale agreements were a primary vehicle for seller-retained security interests. Post-UCC Article 9 (1952 onward), the functional approach collapsed conditional sales, chattel mortgages, and trust receipts into a unified security interest framework. Historical sources treating "conditional sale" as a distinct transaction type are not wrong for their era but require translation into modern doctrine.

In criminal law research, "conditional release" encompasses parole, probation, supervised release, and bail — each with distinct statutory frameworks, revocation procedures, and constitutional dimensions. The word "conditional" in a historical criminal law source may not map cleanly onto any single modern category.

The Rapalje & Lawrence entry flags an important usage: "condition" as equivalent to "restriction" or "stipulation" in property contexts, particularly in English land registration practice. Researchers encountering "conditions" in English land transfer documents should not assume the term carries the full doctrinal freight of a condition precedent or subsequent — it may simply mean a recorded use restriction.

Historical Dictionary Support

Black's Law Dictionary (both editions) defines "conditional" economically: dependent upon or granted subject to a condition. The second edition extends the definition by cataloguing compound terms — conditional creditor, conditional stipulation, conditional acceptance, conditional bequest — illustrating that the term's legal significance is almost entirely carried by its noun companions rather than by any freestanding doctrine.

Rapalje & Lawrence add the important note that "condition" in property usage slides into "restriction" or "stipulation," particularly in the context of conditions of sale and English land transfer registration. This usage is not fully captured in Black's and represents a genuine gap between the doctrinal and the transactional senses of the word.

Neither historical dictionary adequately addresses the trajectory of "conditional sale" through the 20th century or the fragmentation of "conditional release" into distinct criminal law categories — both developments postdate the core editions of these works.

Jurisdictional Note

The civil law concept of conditional creditor (creditor with a right in expectancy) has continuing relevance in Louisiana and in federal bankruptcy proceedings where civil law categories inform proof of claim analysis. Common law jurisdictions have no direct equivalent, though the concept maps roughly onto contingent claims. Researchers should not assume the term operates identically across civil and common law systems.

(258) 14. Conditions of sale. Condition is also used as equivalent to "restriction" or "stipulation," e. g. conditions of sale (q. v.) 15. Registration of conditions.-The English Land Transfer Act, 1875, provides for the registration, as annexed to registered land, of conditions that the land is not to be built on or put to a particular use, or of any other con ditions running with or annexed to land. 284. See COVENANT. created upon an incertaine event." (Co. Litt 201 a.) (As to estates on condition, see ESTATE.) Formerly, "condition" included both conditions in the strict sense, and what are now more commonly called "conditional limitations," the distinction being that when a freehold estate is limited to cease on a condition, and the condition happens, the person in whose favor the condition is reserved must make an entry or claim, otherwise the estate continues; in the case of a conditional limitation, on the other hand, the estate determines ipso facto on the happening of the event, and the remainder or reversion takes effect in immediate possession. (Co. Litt. 214b; Fearne Rem. 15; Leake Dig. 223. See LIMITATION.) If, however, a leasehold unknown event, upon which an obligation takes estate is granted on condition, it determines ipso facto on breach of the condition without any entry being required, unless an entry is expressly stipulated. Co. Litt. 214b; Leake Dig. 226. 12. Various other kinds of conditions. Conditions are also called "affirmative," when positive; "collateral," when they require the performance of a collateral act; "compulsory," when express or imperative; "consistent," when in agreement or accord with other parts of the transaction out of which they arise; "copulative," when they are the aggregate of separable conditions, all of which must be performed; "covert," when implied (see supra& 85); "disjunctive," when they require one of several things to be done; "inherent," when annexed to something reserved in the grant; "insensible," or "repugnant," when inconsistent with or opposed to the original act; "positive," when they require the happening of a contemplated event; "restrictive," when they restrain or forbid the doing of an act; "single," when the performance of a single act only is required; "void," when of no effect or validity. 13. Assignment of conditions.- Formerly, a condition was not assignable in any way, but by Stat. 32 Hen. VIII. с. 34, a condition annexed to a reversion passes en an assignment of the reversion. Wms. Real Prop. 246. See ENTRY. As to the apportionment of conditions, see APPORTION, 24. 16. Conditions in the French law. - In French law, the following peculiar dis tinctions are made: (1) A condition is casuelle, when it depends on a chance or hazard; (2) a condition is potestative, when it depends on the accomplishment of something which is in the power of the party to accomplish; (3) a condition is mixte, when it depends partly on the will of the party and partly on the will of others; (4) a condition is suspensive, when it is the future and uncertain event, or present but or fails to take effect; (5) a condition is resolu toire, when it is the event which undoes an obligation which has already had effect as such.
