Definition
Having a mutual or reciprocal relation such that the existence of one thing necessarily implies the existence of the other. A correlative relationship is one of logical and legal interdependence: neither term or right exists in isolation, and each defines the other.
In legal usage, the concept operates at two levels:
1. Correlative terms: Paired concepts that are mutually defining. "Right" and "duty" are the canonical legal example — every right implies a corresponding duty in another party, and no duty exists without a corresponding right. "Father" and "son," "creditor" and "debtor," "lessor" and "lessee" function similarly.
2. Correlative rights (property law): A doctrine governing shared natural resources — most prominently groundwater and surface water — under which each owner overlying a common resource holds rights that are limited by, and must be exercised consistently with, the equal rights of other overlying owners. No single owner may take so much of the shared resource as to unreasonably deprive other correlative rights holders of their proportionate share.

Common Language
Modern common usage (Wiktionary): Either of two correlative things; also a grammatical term for pro-forms in paired constructions.
Historical common usage (Webster's 1913): Having or indicating a reciprocal relation — illustrated by paired social roles such as father and son, prince and subject.
The common meaning and the legal meaning are closely aligned at the conceptual level, but legal usage carries significant doctrinal weight that ordinary usage does not. Calling two things "correlative" in conversation is descriptive; in law, identifying rights as correlative imposes enforceable mutual limitations. The correlative rights doctrine in water law, in particular, is a formal legal standard with consequences for priority, allocation, and remedy — far beyond the relational observation that the common word conveys.

Recognized Forms
/SUBTYPES
Correlative terms: Paired legal concepts defined by mutual implication. The Hohfeldian framework formalized this most rigorously: right/duty, privilege/no-right, power/liability, immunity/disability are the classical jural correlatives, each pair describing a bilateral legal relationship from opposite perspectives.
Correlative rights doctrine: A water law principle applied most prominently to groundwater and, in some jurisdictions, to surface water. Overlying landowners share rights in a common resource proportionately; each may make reasonable use, but none may waste or appropriate beyond a fair share to the detriment of others. The doctrine mediates between absolute ownership (each owner may take freely) and prior appropriation (first in time, first in right), staking out a middle position in which concurrent users hold co-equal, mutually limiting entitlements.

Why It Matters in Research
The term "correlative" appears in two largely separate research streams that require different navigational strategies.
In jurisprudence and rights theory, researchers encountering "correlative" are likely working in the Hohfeldian tradition, which repurposed and systematized the term in the early twentieth century. Wesley Newcomb Hohfeld's analysis of jural relations — distinguishing rights, privileges, powers, and immunities, each with its correlative — is foundational to Anglo-American analytical jurisprudence and appears throughout academic legal literature, constitutional theory, and sophisticated private law scholarship. Historical dictionaries predate or ignore Hohfeld; their definitions capture the intuitive pairing concept but not the systematic analytical apparatus that followed.
In property law research, "correlative rights" signals a specific water law doctrine with a distinct geographic footprint. California's development of the correlative rights doctrine for groundwater is historically significant and heavily litigated. Researchers working in western water law must distinguish correlative rights from prior appropriation and from reasonable use doctrines — these are not synonyms, and jurisdiction determines which applies. Sources from eastern states may use the language of reasonable use without the formal correlative rights framework, and the terms are sometimes used loosely as near-equivalents in secondary literature.
A trap for corpus researchers: older sources using "correlative" in rights discussions are almost certainly not referring to the water law doctrine. Context — jurisprudential versus property — determines which meaning is operative. Anderson's Dictionary of Law provides no independent entry and redirects to ASSENT, which is of limited help; researchers relying solely on Anderson will miss the full doctrinal range.
The term also appears in tax and commercial law contexts — correlative adjustments in transfer pricing, correlative obligations in contract — where it retains the general mutual-implication meaning without invoking either the Hohfeldian or water law frameworks specifically.

Historical Dictionary Support
The historical dictionaries are in close agreement on the core definition: a mutual or reciprocal relation in which the existence of one thing implies the existence of the other. Black's (both editions), Burrill, and Rapalje & Lawrence all lead with this formulation and illustrate it with the same examples — father/son and right/duty — suggesting a stable, shared understanding across the nineteenth-century legal lexicon.
Burrill adds the Latin derivation (con + relativus), which illuminates the concept etymologically but adds little doctrinally. Rapalje & Lawrence note the right/duty pairing explicitly, which anticipates the more rigorous Hohfeldian treatment without developing it.
What the historical dictionaries uniformly miss is the correlative rights doctrine as a distinct property law principle. This is not a failure of the sources — the doctrine developed primarily in the late nineteenth and early twentieth centuries in California water litigation — but researchers should not expect historical dictionary entries to illuminate the water law usage. Similarly, the Hohfeldian analytical system, which gave "correlative" its most precise legal-philosophical meaning, postdates these dictionaries and appears nowhere in them.
Anderson's entry is an outlier, offering only a cross-reference to ASSENT with no substantive definition — an anomaly that may reflect an organizational choice in that dictionary rather than any meaningful connection between the terms.

Jurisdictional Note
The correlative rights doctrine as a water law framework is most fully developed in California and a small number of western states. Many states apply prior appropriation or reasonable use doctrines instead, and the term "correlative rights" may not appear in those jurisdictions' water law at all. Researchers should not assume the doctrine's applicability outside jurisdictions where it is expressly recognized.
