Definition
And independent is a term of art in the law of covenants describing the relationship between two contractual obligations where performance of one does not depend upon prior or concurrent performance of the other. When covenants in a contract are "and independent," each party's duty to perform stands alone — a breach or non-performance by one party does not excuse the other from fulfilling its own obligation.
The term is the counterpart to dependent covenants, where performance of one obligation is a condition precedent to the duty of the other party to perform. The distinction carries significant consequences: if covenants are and independent, the non-breaching party must still perform and seek damages separately; if covenants are dependent, the other party's breach may justify suspension or refusal of performance.

Common Confusion
And independent covenants are frequently confused with concurrent conditions and with dependent covenants, and the lines between them shifted considerably as courts moved from strict common-law classification toward the modern doctrine of material breach. Under classical covenant law, the determination of whether covenants were independent or dependent was largely a formal inquiry driven by the structure of the instrument. Under modern contract law, the same question tends to be resolved through analysis of the parties' intent and the materiality of any breach — making the old label less dispositive but still relevant in jurisdictions that retain traditional covenant doctrine, particularly in real property and lease contexts.
Do not confuse "and independent" (a description of how two obligations in the same instrument relate to each other) with the constitutional doctrine of adequate and independent state grounds (which concerns whether a state court decision rests on state law grounds sufficient to insulate it from federal review). The word overlap is coincidental; the concepts are unrelated.

Why It Matters in Research
Researchers encounter and independent most often in three contexts: (1) pre-twentieth-century contract and conveyancing disputes, where courts analyzed covenant structure using the dependent/independent framework; (2) landlord-tenant law, where the independent covenant rule historically meant that a tenant's obligation to pay rent was not excused by a landlord's failure to maintain the premises — a rule since abrogated or qualified in most jurisdictions; and (3) real covenant and deed restriction cases, where the running of obligations with land sometimes turns on how the original covenants were classified.
The primary trap in historical sources is treating the dependent/independent distinction as if it were purely a question of contract interpretation. At common law it was often a formal, nearly mechanical inquiry: courts examined whether performance was linked by the instrument's own language, not by inference about intent. Modern readers applying current contract principles to historical cases risk misreading outcomes.
In corpus research, and independent appears most frequently in treatises and reporters from the eighteenth and nineteenth centuries. By the mid-twentieth century the terminology largely receded in favor of material breach analysis, though it persists in property law scholarship and in jurisdictions with strong lease covenant traditions. When reading older authorities, note whether the court is applying the traditional classification or already moving toward the modern approach — conflating the two frameworks produces distorted readings.
The term is also relevant to the constitutional_44 encyclopedia entry (Adequate and Independent State Grounds), not because the legal concepts overlap, but because researchers searching historical sources for "independent" in a legal context may surface covenant cases alongside constitutional ones. Knowing the distinction prevents cross-contamination of research threads.

Historical Dictionary Support
Rapalje & Lawrence define the relationship concisely: "where the obligation to perform one covenant depends upon the performance of another." The entry uses the term to mark the boundary condition — and independent covenants exist precisely where this dependency is absent. The definition is accurate but minimal, reflecting the assumption that nineteenth-century practitioners already knew the broader framework.
What Rapalje & Lawrence do not address is the doctrinal evolution underway even at the time of their writing. The leading English authorities had already begun qualifying the strict independence rule in lease contexts, and American courts were reaching inconsistent results on whether a landlord's breach of a duty to repair could excuse rent. The historical dictionary captures the formal rule without flagging this tension. Researchers relying solely on the Rapalje & Lawrence definition will find it accurate for the core concept but incomplete for understanding how courts actually applied it at the margins.
No significant divergence among the major historical dictionaries on the core meaning — the and independent / dependent covenant distinction was well-settled in its basic formulation. The doctrinal controversy was in application, not definition.

Jurisdictional Note
The practical significance of the and independent / dependent distinction varies sharply by context. In landlord-tenant law, most U.S. jurisdictions have modified or abolished the traditional independent covenant rule for residential leases through statute or judicial adoption of the implied warranty of habitability. Commercial lease law is less uniform, and the traditional rule retains more force in some jurisdictions. In the law of real covenants and deed restrictions, the independent covenant framework continues to appear in case law across common-law jurisdictions.
