Definition
A condition affirmative is a contractual or conveyancing condition that requires a party — typically the grantee or lessee — to do some positive act. The condition is satisfied by performance, and failure to perform triggers the consequence attached to the condition, typically forfeiture of the estate or interest. The defining characteristic is the active obligation: the burdened party must affirmatively act, not merely refrain from acting.
The classic illustration drawn from both Black's and Burrill is a lease provision requiring the lessee to pay rent. The condition is not a mere promise — it is a structural element of the grant itself, such that nonperformance places the estate at risk.
Common Confusion
CONDITION AFFIRMATIVE vs. AFFIRMATIVE COVENANT: These are not the same thing. A condition affirmative is a condition — breach risks forfeiture of the estate. An affirmative covenant is a promise — breach gives rise to a claim for damages or equitable relief. The distinction matters both for remedy and for whether the obligation runs with the land to bind successors. Modern property law has largely absorbed both concepts into the law of servitudes, but historical sources treat them as categorically distinct, and researchers must not read one into the other when interpreting older instruments.
CONDITION AFFIRMATIVE vs. CONDITION PRECEDENT: A condition affirmative describes the nature of the required act (doing something positive). A condition precedent describes the timing relationship between the condition and the vesting of the right (the condition must be fulfilled before the interest arises). A condition can be both affirmative and precedent simultaneously, or affirmative and subsequent. These are different axes of classification.
Why It Matters in Research
The phrase "condition affirmative" is largely a term of historical art. Researchers working in modern property, contract, or landlord-tenant materials will rarely encounter it by name. Its analytical work is now done under the broader rubrics of conditions precedent, conditions subsequent, and affirmative covenants. Knowing the historical term helps researchers decode older deed language, treatise discussions, and equity court decisions that distinguish the nature of obligations imposed on grantees.
The most important research trap is conflating a condition affirmative with an affirmative covenant. In modern practice, the two are often treated interchangeably in casual usage, but historically they carried distinct legal consequences — particularly regarding enforceability against successors and the remedy for breach. A condition could work a forfeiture; a covenant's remedy was damages or injunction. Researchers tracing the evolution of real covenant doctrine and equitable servitude doctrine should anchor that analysis in the condition/covenant distinction that older sources, including Shepard's Touchstone, elaborate at length.
A secondary research consideration: because this term appears in older conveyancing treatises and early English property law sources, it is more likely to surface in American materials predating the mid-twentieth century. Post-1950 American case law and statutes rarely use the phrase. Researchers in colonial-era land grants or nineteenth-century deed interpretation disputes will find this term operational; researchers in modern residential real estate will not.
Historical Dictionary Support
Both Black's Law Dictionary and Burrill's Law Dictionary define condition affirmative consistently: it is "a condition which consists in doing a thing," and both cite Sheppard's Touchstone of Common Assurances (p. 118) as the source authority. The agreement between the two dictionaries on both the definition and the citation is notable and reflects that this was a settled, if narrow, term of the English conveyancing tradition imported into American legal writing.
Neither dictionary elaborates extensively on condition affirmative in isolation; the term gains full meaning only in contrast with condition negative (a condition requiring abstention from an act). Black's contextual material — distinguishing conditions from covenants and noting that only a grantor can impose a condition while either party can make a covenant — fills in the structural framework that the bare definition omits. Burrill's treatment is similarly sparse. Neither source addresses what modern property scholars would call the running of conditions with the land, a gap that matters considerably for researchers working on servitude history.
Sheppard's Touchstone, the common authority cited, is an early English conveyancing manual that remained influential in American courts well into the nineteenth century. Its framework for classifying conditions — affirmative versus negative, precedent versus subsequent — shaped how American equity and law courts analyzed deed conditions for generations.
