Definition
A condition precedent is an event or act that must occur or be performed before a contractual obligation becomes enforceable, an estate vests, or a right accrues. Until the condition is satisfied, the duty or interest to which it is attached does not arise — it is suspended, not merely delayed.
The term operates across two principal legal contexts:
1. Contracts. A condition precedent is a fact or event that must exist or occur before a party's duty to perform under a contract is triggered. If the condition fails, the obligation never ripens, and the non-occurrence does not itself constitute breach by the party whose performance was conditioned. This distinguishes a condition from a promise: failing a condition excuses performance; failing a promise creates liability.
2. Property / Estates. A condition precedent must be satisfied before title can vest or an estate can be enlarged. Until the condition is met, the estate does not pass to the grantee. The classic illustration: a grant conditioned on the payment of a sum certain before a specified date — the fee does not vest until payment is made.
Common Language
Wiktionary: "A condition imposed on an agreement that must be satisfied before property is transferred between parties; a condition depending upon an uncertain event which must be fulfilled before an obligation arises or a legal transaction takes effect."
The Wiktionary definition captures the mechanics adequately, but it understates the significance. In ordinary speech, "condition" suggests a limitation or requirement. In law, the distinction between condition precedent, condition subsequent, and concurrent condition determines whether a duty ever arises, whether a duty is extinguished, or whether duties are mutually dependent. The common-language definition does not convey that the failure of a condition precedent typically produces no breach — it simply means no obligation materializes.
Common Confusion
Condition precedent vs. condition subsequent. These terms are frequently conflated because both involve conditions attached to legal duties or estates. The distinction is directional: a condition precedent must occur before a duty or estate arises; a condition subsequent operates after a duty or estate has already arisen, and its occurrence terminates or defeats it. In contracts, failure of a condition precedent means the duty never attached. Occurrence of a condition subsequent means a duty that had already attached is discharged.
Condition vs. promise. A party's failure to perform a condition does not itself give the other party a cause of action for breach — it simply excuses the other party's performance. A promise, by contrast, creates an independent duty, and its breach generates liability. Some terms in a contract function simultaneously as both condition and promise; courts determine which characterization applies by examining the parties' intent and the consequences of non-occurrence.
Core Elements
For a condition precedent to operate in contract law, three elements are typically examined:
1. Identification of the condition. The event or act must be identifiable as a condition — distinguished from a mere promise or recital — by reference to language ("if," "provided that," "on the condition that," "when") or by the logical structure of the agreement.
2. Non-occurrence or non-performance. The condition must in fact have failed to occur or be performed within the time and manner specified, or as required by the agreement's reasonable construction.
3. Absence of prevention or waiver. The condition will be treated as satisfied if the party whose duty depends on it wrongfully prevented its occurrence. Similarly, a party may waive the condition, in which case the duty is triggered despite non-occurrence.
Recognized Forms
/SUBTYPES
Express condition precedent. Explicitly stated in the agreement, typically through conditional language.
Implied condition precedent. Not stated in so many words but inferred from the structure and evident intent of the agreement. Courts recognize implied conditions where the parties' performance was clearly meant to be contingent on a prior event.
Constructive condition precedent. Imposed by operation of law, typically to give effect to the order of performance — courts treat a first-in-time performance obligation as a constructive condition precedent to the other party's duty, even absent express conditional language.
Why It Matters in Research
Terminology shift in older sources. Pre-twentieth-century legal writing applies "condition precedent" almost exclusively in property and estates contexts. When researching historical contracts doctrine, be alert to this narrower usage; early treatises may treat what modern contract law calls a condition precedent as merely part of the consideration analysis.
The condition/promise distinction is a research trap. Cases involving conditions precedent often turn on classification — condition or promise? — and historical courts were not uniform in methodology. A researcher tracing the development of this distinction will find sharp divergence between equity courts (which often relieved against forfeiture from failed conditions) and courts of law.
Parol evidence implications. Courts have long allowed extrinsic evidence to show that a written agreement was subject to an oral condition precedent to the agreement's effectiveness — this is a significant exception to the parol evidence rule. The Law Mind Contracts Encyclopedia addresses this directly in contracts_41. Researchers working with integrated written contracts should not assume that the parol evidence rule bars all evidence of conditions; the precedent condition exception has a distinct doctrinal history.
Real property context. In historical property research, the Burrill formulation — "a condition preceding an estate" — tracks the classical common-law rule precisely. Vesting is postponed, not contingent on a subsequent defeasance. Researchers should distinguish this from conditions subsequent in deeds, which vest title subject to defeasance, producing very different chain-of-title implications.
Financing and commercial transactions. Modern transactional practice makes extensive use of conditions precedent in loan agreements, acquisition contracts, and real estate purchase agreements (e.g., financing contingencies, due diligence periods, regulatory approval requirements). These modern usages descend directly from the classical doctrine but are layered with negotiated specificity that historical sources do not anticipate.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary converge on the core definition: a condition that must happen or be performed before the estate or right to which it is annexed can vest or be enlarged. Both sources anchor the concept in property law, and both use the same illustrative structure — a lessee who earns a fee only upon timely payment.
Black's extends the definition to contracts, noting that a condition must be performed before the contract becomes operative, aligning with the modern contracts usage. Burrill's remains closer to the property-law formulation, consistent with its classical orientation.
Neither historical source develops the condition/promise distinction as modern contract law has, nor do they treat constructive conditions with any analytical depth. The parol evidence exception for oral conditions precedent to a written agreement's effectiveness — a significant modern application — is absent from both. Researchers relying on these sources for contracts doctrine will need to supplement them with twentieth-century treatise authority.
Jurisdictional Note
The substantive doctrine of condition precedent is consistent across American jurisdictions, but states diverge on how courts classify ambiguous contract terms — particularly whether to treat a term as a condition, a promise, or both. Some jurisdictions express a preference against finding conditions precedent when the consequence would be forfeiture, resolving interpretive doubt in favor of promise rather than condition. This interpretive default is not universal and should be confirmed for any specific jurisdiction.
