Definition
DEPENDENT functions as both an adjective and a noun in legal usage, and the two meanings operate in largely separate doctrinal contexts.
1. As an adjective: Conditioned upon or subordinate to some other act, fact, or obligation. A legal duty, contract, or covenant described as dependent is one that does not arise or become enforceable until some connected performance has first occurred on the other side. The force of the obligation is not self-contained — it waits on something external.
2. As a noun: A person who relies upon another for financial support and who has not the independent means or legal capacity to provide for themselves. The term appears across family law, tax law, benefit programs, veterans' law, insurance, and immigration, with each field applying its own definitional criteria.

Common Language
Modern common usage (Wiktionary): Relying upon; depending upon. Hanging down. (Also: in statistics, a probability affected by a separate event.)
Historical common usage (Webster's 1913): Hanging down; relying on something else for support; not self-sustaining; contingent or conditioned; subordinate.
The ordinary meaning tracks the legal meaning closely in feel but not in consequence. In common speech, "dependent" describes a general condition of reliance. In law, the adjective form carries precise technical weight — two covenants described as dependent are not merely related; the sequence of their enforceability is legally fixed and breach analysis changes accordingly. The noun form likewise carries defined qualifying criteria that vary sharply by legal context, and satisfying the ordinary intuition of "relying on someone" is not sufficient to establish dependent status under most legal tests.

Common Confusion
DEPENDENT (adjective) vs. INDEPENDENT (adjective): The distinction between dependent and independent covenants or contracts is not merely descriptive — it determines remedy. Under an independent covenant, each party's obligation stands on its own and a breach by one does not excuse the other's performance. Under a dependent covenant, the other party's performance is a condition precedent, and the contractor need not perform until that condition is met. Historical sources sometimes blur this by treating the terms as a simple binary without flagging the remedial consequences.
DEPENDENT (noun) vs. BENEFICIARY: In insurance and benefit contexts, "dependent" and "beneficiary" are often used loosely as interchangeable. They are not. A beneficiary receives proceeds; a dependent qualifies for coverage or benefits by virtue of a support relationship. A person may be one, both, or neither.

Core Elements
For the adjectival sense (dependent covenant or contract), courts and commentators have identified these distinguishing features:
— Conditionality: Performance by one party is a precondition to the other's duty arising.
— Connection: The obligations must arise from the same agreement or closely linked instruments; entirely separate contracts are not rendered dependent merely by practical relationship.
— Sequence: The dependent obligation comes second in time; determining which party performs first is central to the analysis.
— Breach consequence: Failure of the first performance suspends, and may excuse entirely, the dependent obligation — not merely giving rise to a damages claim.
For the noun sense, qualifying criteria are supplied by the governing framework (tax code, insurance policy, federal benefit statute, etc.) and typically turn on: financial dependency, legal relationship or household membership, age, and sometimes citizenship or residency.

Recognized Forms
/SUBTYPES
Dependent contract / dependent covenant: The primary adjectival usage. An agreement or obligation contingent on prior performance by the other party.
Tax dependent: Defined under the Internal Revenue Code with distinct tests for "qualifying child" and "qualifying relative," each carrying specific age, residency, support, and relationship requirements.
Benefit-program dependent: Defined by the applicable statute or plan document — Social Security, veterans' benefits, military benefits, and employer-sponsored health plans each maintain their own criteria.
Insurance dependent: Determined by policy language; typically includes spouse and minor children but may extend further by statute (e.g., dependent coverage mandates under the Affordable Care Act).

Why It Matters in Research
The two legal meanings of DEPENDENT — adjectival and nominal — are so contextually separated that a researcher must identify which usage applies before selecting sources. Searching a 19th-century legal dictionary for "dependent" to understand a modern tax question will produce contract doctrine, not tax law.
For the adjectival (covenant/contract) sense: Historical sources are the most useful here, because this meaning was most fully developed in 18th- and 19th-century contract law. The distinction between dependent and independent covenants was a live doctrinal question long before modern treatise coverage standardized it. Rapalje & Lawrence and Anderson both address it directly, though neither provides the full remedial analysis a researcher needs. Black's 2nd ed. references Hamilton on Parties for deeper treatment. When reading historical opinions, watch for "conditions precedent" being used as a functional equivalent to "dependent covenant" — terminology was not uniform.
For the nominal (person) sense: Historical dictionaries are largely unhelpful. Anderson's includes the noun definition, but the modern legal content of "dependent" — particularly in tax, benefits, and insurance — is entirely statutory and regulatory, postdating all four source dictionaries. The definitional criteria differ across legal regimes and cannot be generalized across them. A researcher analyzing whether a person qualifies as a dependent must identify the specific governing instrument (statute, regulation, plan document) before the word has operational meaning.
Jurisdictional variation matters for the noun sense in family law and state benefit contexts. State domestic relations law may define "dependent" for child support purposes differently from the federal tax definition, and conflating them is a common research error.
The term also appears in procedural contexts — "depending suit" (a pending suit, per Rapalje & Lawrence citing Pennsylvania authority) — though this usage is largely archaic and confined to older statutory construction questions.

Historical Dictionary Support
The four source dictionaries converge on the adjectival meaning but offer little on the noun.
Rapalje & Lawrence focuses on dependent covenants and contracts, giving the core definition — an obligation not to be performed until the other party has first performed on a connected obligation — but stops short of analyzing the remedial implications. Its citation to 3 Rawle (Pa.) 283 grounds the term in early American case law. It also notes the procedural usage "depending suit" as a statutory term.
Anderson's Dictionary of Law provides the most complete coverage among the four, explicitly contrasting dependent and independent obligations, flagging the comparative term APPENDENT, and including a brief noun definition. Anderson is the only source here that acknowledges both uses.
Burrill's Law Dictionary offers no independent definition, redirecting to Dependent Covenants and Independent Covenants — a useful pointer for researchers who need to locate deeper doctrinal treatment but unhelpful standing alone.
Black's 2nd ed. provides a compact definition for the adjectival sense and cross-references Hamilton on Parties for the contract context. Black's is the most widely cited of the four but adds little beyond what Anderson and Rapalje & Lawrence supply.
All four sources treat the term primarily through the lens of 19th-century contract doctrine. None anticipates the noun's dominant modern significance in tax and benefits law. Researchers relying on these dictionaries alone will have an incomplete and potentially misleading picture of how "dependent" functions in contemporary legal practice.

Jurisdictional Note
Federal law supplies the dominant definitions for "dependent" in tax, Social Security, veterans' benefits, and immigration contexts — and those definitions are not uniform even within federal law. State law controls in family law proceedings (child support, custody, and inheritance), and state definitions may diverge from federal ones in ways that matter when both frameworks apply simultaneously to the same individual.
