Definition
Implication in law refers to something understood, inferred, or imputed from circumstances, conduct, or language — without being directly stated. It is the legal mechanism by which rights, duties, obligations, and intentions are recognized even when not expressly declared. The term carries distinct meanings depending on context:
1. IMPLICATION IN CONTRACT LAW. A term, promise, or obligation inferred from the conduct of the parties, the nature of the agreement, or the surrounding circumstances, rather than from explicit language. Implied contracts and implied covenants rest on this sense of the word. Where a party has a legal duty to perform, the law may impute a promise to fulfill that duty without any express agreement.
2. IMPLICATION IN PROPERTY LAW. The transfer or creation of property interests — including estates, easements, and covenants — that arise not from express words but from the evident intention of the parties or the prior state of the land. A testator's will may pass an estate by implication alone if the intent can be fairly inferred from the document as a whole. Easements by implication arise when prior use or necessity makes their existence a reasonable inference from a conveyance.
3. IMPLICATION IN STATUTORY CONSTRUCTION. When a statute expressly provides for something, courts may recognize implied provisions as a necessary consequence. What is clearly implied in a statute carries the same legal force as what is expressly stated — but the implication must be necessary, not merely possible or conjectural.
4. IMPLICATION IN PLEADING AND EVIDENCE. An inference drawn from what is admitted or expressed in a pleading, document, or set of facts. The implication must be a reasonable and necessary inference, not a remote or speculative one.
Across all these contexts, a foundational constraint applies: implication must be necessary or at least highly probable — never merely possible. Conjecture is not implication.

Common Language
Modern common usage (Wiktionary): A possible, or indirect, effect or result of a decision or action; something implied but not directly stated; also used in formal logic for a conditional connective.
Historical common usage (Webster's 1913): "An implying, or that which is implied, but not expressed; an inference, or something which may fairly be understood, though not expressed in words."
The common and legal meanings share a core sense — something understood without being stated — but diverge in a critical way. In ordinary usage, "implication" is merely suggestive; a thing that might be inferred. In law, implication carries operative force: an implied easement is a real easement, an implied contract is a binding contract, an implied term is enforceable. The everyday sense of implication as a vague inference understates the weight the concept carries in legal instruments and doctrine.

Common Confusion
IMPLICATION vs. INFERENCE. These terms are sometimes used interchangeably, but in legal analysis they point in different directions. An inference is something a reader or factfinder draws from evidence. An implication is something a speaker, drafter, or party has communicated without expressly stating it. The distinction matters most in contract interpretation and statutory construction, where courts must determine whether an obligation arises from what the parties implied or from what a court independently infers.
IMPLICATION vs. CONSTRUCTION. Legal construction fills gaps by applying external rules of law to a situation the parties did not address. Implication, by contrast, operates from within the instrument or relationship itself — deriving meaning from what the parties actually (if silently) intended. An easement by implication rests on the parties' inferred intent; an easement by estoppel or prescription rests on external legal doctrine. Historical sources sometimes blur this line, using "implied" and "constructive" as near-synonyms, which can mislead researchers working with older texts.

Recognized Forms
/SUBTYPES
IMPLICATION OF LAW (implied in law / constructive implication). An obligation or right the law attaches regardless of the parties' actual intent, based on fairness or policy. Quasi-contractual obligations arise this way.
IMPLICATION OF FACT (implied in fact). Arises from the actual conduct, circumstances, or evident intention of the parties. True implied contracts — where no express agreement exists but the parties' behavior demonstrates mutual assent — are implied in fact.
NECESSARY IMPLICATION. The standard most courts apply when recognizing implied provisions in wills, statutes, or deeds. The implication must follow inevitably, or nearly so, from what is expressed — not merely be one of several plausible readings.

Why It Matters in Research
Implication is a term of extraordinary reach in the Law Mind corpus — it surfaces in property law (easements, estates), contract law (implied terms, implied warranties), statutory interpretation, and pleading. Researchers should be alert to several navigational challenges.
First, the implied-in-law / implied-in-fact distinction is not always cleanly observed in historical sources. Older cases and treatises frequently use "implied" to cover both categories, requiring researchers to examine context to determine which doctrine actually applies.
Second, the threshold for recognizing an implication has tightened over time. Early common law was more permissive about what could be inferred from a conveyance or will; modern courts generally demand necessity, not mere probability. Historical sources will reflect the older, more generous standard, which may not reflect current doctrine.
Third, in property law, implication is the mechanism behind easements by prior use and by necessity — two distinct doctrines that are often grouped under the same label. See property_71 in the Encyclopedia for detailed treatment. Researchers conflating these two creation theories will find contradictory case results that only resolve when the distinction is understood.
Fourth, in contract contexts, the modern law of implied terms has been significantly shaped by the implied covenant of good faith and fair dealing, which is a distinct doctrine from general implication analysis. Tracing the development of implied warranty doctrine — especially in sale of goods — requires care because the statutory overlay (UCC Article 2) displaced common law implication rules in most commercial contexts.

Historical Dictionary Support
The five historical dictionaries converge tightly on the core definition: implication is inference from what is admitted or expressed, distinguished from direct statement. All five cite or echo Blackstone's Commentaries on the passage of estates by implication in wills (2 Bl. Comm. 381), reflecting how foundational property law was to the concept's development.
Burrill adds the most precise doctrinal limit, noting that implications "must be such as are necessary (or at least highly probable) and not merely possible" — language that closely tracks how modern courts formulate the standard. Anderson is distinctive in connecting implication to assumpsit, signaling the term's role in the development of implied contract doctrine; his entry also flags the parallel between implication and imputed obligation, noting that where a duty exists, the law imputes a promise to perform.
Bouvier's entry is the sparsest, but its cross-references (CONTRACT, DEED, EASEMENT, WAY) usefully map the term's spread across substantive fields. What no historical source fully addresses is the implied-in-law / implied-in-fact distinction as a formal doctrinal category — a division that courts and commentators sharpened considerably in the nineteenth and twentieth centuries. Researchers relying solely on historical dictionaries will find the vocabulary but not the categorical framework.

Jurisdictional Note
Implication doctrine varies most significantly in property law. Some states require strict necessity before implying an easement; others recognize easements from prior use under a less demanding standard of reasonable necessity. In contract law, the extent to which courts will imply terms — particularly quality and fitness warranties — is heavily influenced by whether the UCC or common law governs the transaction.
