Definition
An entire contract is a contract in which all of its parts and obligations are so interconnected that they form a single, indivisible whole. Performance of the contract is treated as a unit: a party must complete all of its promised obligations before becoming entitled to the full consideration. This stands in direct contrast to a severable (or divisible) contract, in which distinct portions can be treated as independent agreements capable of separate enforcement and separate payment.
The distinction carries real consequences. Under an entire contract, a party who performs only part of their obligations has technically breached the whole, and may recover nothing — or only a quantum meruit recovery for partial performance — rather than a proportional share of the contract price. Under a severable contract, a party who completes one identifiable portion may recover for that portion even if they fail to complete another.
The test is not how many parts a contract contains, but whether the consideration is single and entire. If one indivisible consideration supports all the obligations, the contract is entire. If each portion of performance has its own corresponding portion of consideration, the contract is severable.

Common Confusion
ENTIRE CONTRACT vs. SEVERABLE (DIVISIBLE) CONTRACT: These two terms define opposite ends of a spectrum, and the line between them is frequently litigated. A contract with multiple deliverables, installment payments, or phased obligations is not automatically severable. Courts look to whether the parties intended each component to stand independently and whether a distinct price attaches to each. A construction contract with progress payments may still be entire if full completion was the contemplated exchange. Researchers should not assume that complexity or length makes a contract severable.
ENTIRE CONTRACT vs. INTEGRATED CONTRACT: These are distinct concepts. An integrated (or integrated written) contract refers to a document that embodies the complete and final agreement of the parties, implicating the parol evidence rule. An entire contract refers to the indivisibility of obligations and consideration. A contract can be entire without being fully integrated, and fully integrated without being entire.
ENTIRE CONTRACT CLAUSE: Insurance policies and some commercial contracts include a clause stating that the written instrument represents the entire agreement between the parties — similar in function to an integration clause. This usage of "entire contract" refers to completeness of the written instrument, not to the indivisibility of performance obligations. Researchers working with insurance law sources will encounter this usage frequently; it is a different concept sharing the same name.

Core Elements
Whether a contract is entire turns on two inquiries:
1. Unity of consideration. Is there a single, undivided consideration for all the promises in the contract? If yes, the contract is entire. If each promise has its own corresponding price or exchange, the contract is likely severable.
2. Intent of the parties. Would the parties have entered each portion of the agreement independently? Courts examine the structure of payment, the subject matter, and the language of the agreement to determine whether the parts were meant to stand alone or only together.

Why It Matters in Research
The entire/severable distinction is one of the more consequential structural classifications in contract law, with significant practical stakes for breach and recovery analysis. Researchers must watch for two overlapping uses of the phrase "entire contract" in the corpus:
First, the performance-indivisibility sense described above — whether a breaching party can recover pro-rata compensation. This is the classic common law meaning and the sense Black's Law Dictionary addresses.
Second, the entire-contract clause in insurance law — a statutory and regulatory concept in many U.S. jurisdictions requiring that the insurance policy itself constitute the whole agreement, preventing insurers from incorporating external documents that the insured never received. These two uses appear in completely different doctrinal contexts but share the same label. Historical sources will not always flag the distinction clearly.
The entire/severable framework appears across multiple areas of the Law Mind corpus: contract formation and breach, construction law, employment agreements, and installment sale disputes. When a historical source describes a contract as "entire," confirm which sense is intended before applying the principle.
Researchers working in equity will also encounter the related doctrine of substantial performance, which emerged partly to soften the harsh results that the entire contract rule could produce. The two doctrines are in tension and should be read together.

Historical Dictionary Support
Black's Law Dictionary provides the foundational formulation: where a contract's parts may be considered as parts of one whole, the contract is entire; where the parts may be considered as so many distinct contracts expressed in the same instrument but not made one contract thereby, the contract is severable. Black's then applies the single-consideration test as the controlling criterion.
This formulation is consistent with the common law treatment that predates the American codifications. The core principle — that a single, entire consideration makes the contract entire — is well-settled and does not vary significantly across historical dictionary sources. What historical sources understate is the equitable softening through substantial performance doctrine, which developed in parallel and is now the dominant framework in many jurisdictions when addressing partial performance by a non-breaching or substantially completing party.
Historical sources also do not distinguish the entire-contract clause in insurance law, which is a later statutory development. Researchers using older reference works for insurance questions should supplement with statutory materials.

Jurisdictional Note
Most U.S. jurisdictions follow the single-consideration test for determining whether a contract is entire or severable, but courts vary significantly in how readily they will find a contract severable to avoid forfeiture. Restatement (Second) of Contracts § 240 provides guidance on divisibility, and many courts cite it, though state common law diverges in application. In insurance law, "entire contract" statutes exist in nearly all U.S. states but differ in scope and effect.

Encyclopedia Cross-Reference
Mergers and Acquisitions — Freeze-Out Mergers and Entire Fairness (The Law Mind Business Organizations & Corporate Law Encyclopedia): Note that "entire fairness" in corporate law is an unrelated doctrine — the standard of judicial review applied to self-dealing transactions between controlling shareholders and minority shareholders. The shared word "entire" is coincidental. Researchers should not cross-apply contract law principles of entire contracts to the corporate entire fairness standard.
