Definition
A resolutory condition is a condition attached to an existing obligation that, upon its occurrence, automatically extinguishes or revokes that obligation — returning the parties to the position they occupied before the obligation arose. Unlike a suspensive condition, which delays an obligation's effect until an uncertain event occurs, a resolutory condition does not suspend performance. The obligation is immediately operative and binding; it is only the subsequent occurrence of the specified event that undoes it.
The defining feature is retroactive dissolution: when the condition is fulfilled, the contract or obligation is treated as though it never existed, and any performance already rendered must generally be restored. The creditor is obliged to return what was received.
Example: A seller agrees to sell a crop of cotton on the condition that a named ship does not arrive within six months. The ship arrives in one month. The contract is revoked as of that event — not merely suspended, but extinguished.
The concept is native to civil law systems and appears in codified form in the Louisiana Civil Code, which defines it as a condition that, when accomplished, "operates the revocation of the obligation, placing matters in the same state as though the obligation had not existed."
Common Confusion
Resolutory condition is frequently confused with its civil law counterpart, the suspensive condition. The distinction is foundational:
A suspensive condition (condition precedent in common law terms) delays the birth of an obligation. Nothing is owed until the event occurs.
A resolutory condition (condition subsequent in approximate common law terms) permits the obligation to take full immediate effect but subjects it to dissolution if a specified event later occurs.
The approximate common law analog is the condition subsequent, but the mapping is imprecise. Common law does not treat a condition subsequent as automatically retroactively voiding a completed obligation in the same mechanical way civil law treats a resolutory condition. Researchers working across civil and common law sources must not treat these terms as interchangeable.
Why It Matters in Research
This term is primarily a civil law term and will appear most densely in Louisiana materials, Louisiana Civil Code commentary, and sources treating French, Spanish, or Roman-derived legal systems. Researchers working in common law jurisdictions will encounter it rarely, and almost exclusively in comparative law discussions or in contexts where civil law doctrine has been imported — notably in Louisiana contracts, international commercial agreements, and academic treatises on obligations.
The critical research trap: English-language common law dictionaries sometimes define resolutory condition loosely as a synonym for condition subsequent. While the concepts overlap functionally, they are not identical in operation or consequence. Using these terms interchangeably when reading Louisiana or international sources will produce errors.
In historical American sources predating Louisiana's modern codification revisions, the doctrine appears framed in French civilian vocabulary. Researchers consulting 19th-century Louisiana cases or treatises will see resolutoire used directly, sometimes without translation.
The retroactivity principle — that fulfillment of the condition restores the pre-obligation state — has significant practical implications in property and commercial research. A resolutory condition in a deed or conveyance can mean that title reverts automatically upon the condition's occurrence, without a judicial proceeding to declare forfeiture. This distinguishes it from common law conditions subsequent in property law, where enforcement often requires legal action.
When researching conditions in international contracts (especially those governed by UNIDROIT principles or French law), resolutory condition will be the operative term. Researchers should not substitute condition subsequent without verifying that the source jurisdiction's doctrine matches.
Historical Dictionary Support
All three source dictionaries — Black's, Rapalje & Lawrence, and Bouvier's — agree on the core definition: a resolutory condition is one whose accomplishment revokes a prior obligation. The definitions are notably convergent, reflecting the term's origin as a technical civil law concept with fixed meaning, leaving little room for interpretive drift.
Bouvier's illustrates the concept with the ship arrival example (the seller's obligation is extinguished when the named ship arrives within the forbidden period), which is the clearest pedagogical rendering among the three sources. Black's directly quotes the Louisiana Civil Code, grounding the definition in enacted law rather than general principle. Rapalje & Lawrence is the most compressed, offering only the functional description without illustration or statutory anchor.
What the historical dictionaries do not address: none of the three discusses the retroactivity mechanism in detail, nor do they engage with the tension between resolutory condition and the common law condition subsequent. Researchers relying solely on these entries for cross-system comparison will need to supplement with civilian treatises on the law of obligations.
Jurisdictional Note
Resolutory condition is operative doctrine primarily in Louisiana, where it is codified in the Civil Code. In other American jurisdictions, the concept has no independent existence as a term of art; common law courts reaching for equivalent doctrine will use condition subsequent. Researchers analyzing contracts with choice-of-law clauses or international agreements should determine which legal system governs before selecting terminology.
