Definition
To rescind a contract or agreement is to undo it — to treat it as though it never existed. Rescission is not merely cancellation going forward; it is a retroactive annulment that restores both parties, as nearly as possible, to their pre-contract positions. The act of rescinding may be performed by a party (unilateral rescission, typically on grounds such as fraud, mutual mistake, failure of consideration, or material breach) or by mutual agreement of both parties (mutual rescission). Courts may also decree rescission as an equitable remedy.
Rescission is distinct from termination or cancellation, which operate prospectively. When a contract is rescinded, it is treated as void from inception — obligations under it are extinguished, and any performance already rendered must be restored through restitution.

Common Language
Modern common usage (Wiktionary): "To repeal, annul, or declare void; to take (something such as a rule or contract) out of effect."
Historical common usage (Webster's 1913): "To vacate or make void, as an act, by the enacting authority or by superior authority; to repeal; as, to rescind a law, a resolution, or a vote."
The common usage is broad and comfortable with non-contractual contexts — rescinding a law, a vote, or a resolution. Legal usage is far more exacting. In contract law, rescission carries the specific consequence of retroactive nullification and triggers restitutionary obligations. A researcher who treats "rescind" as a loose synonym for "cancel" or "repeal" will misread the legal stakes involved in any given transaction dispute.

Common Confusion
RESCIND vs. TERMINATE: Termination ends a contract prospectively; future obligations are discharged, but past performance stands. Rescission, by contrast, reaches back to the beginning — the contract is treated as never having been made. This distinction controls whether a party can recover contract damages (available after termination for breach) or restitution (the remedy after rescission).
RESCIND vs. VOID/VOIDABLE: A void contract requires no act of rescission — it has no legal effect from the start. A voidable contract remains in force until the aggrieved party elects to rescind it. The act of rescinding is the mechanism by which a voidable contract is undone; the two concepts are related but not interchangeable.
RESCIND vs. CANCEL: "Cancel" is common in commercial usage but lacks the retroactive and restitutionary implications of rescission. Historical legal sources occasionally use the terms interchangeably; modern usage has sharpened the distinction.

Core Elements
For rescission to be effective — whether by party action or court decree — several conditions are generally required:
1. Grounds: A recognized basis must exist. Common grounds include fraud or misrepresentation, mutual mistake, unilateral mistake (in limited circumstances), failure or total lack of consideration, duress, undue influence, or material breach by the other party.
2. Election and timeliness: The right to rescind is elective and can be waived. A party who affirms the contract after learning of the ground for rescission — by continuing performance, accepting benefits, or unreasonable delay — may lose the right.
3. Notice: The rescinding party must communicate the election to rescind clearly and promptly.
4. Restoration (restitution): The rescinding party must offer to restore any benefit received under the contract. This condition of mutual restoration is central — rescission is not a mechanism for retaining performance while avoiding counter-performance.

Why It Matters in Research
The most important navigational point for corpus researchers: the term "rescission" appears in two distinct registers in legal sources — at law (a self-help remedy pursued by a party) and in equity (a court-ordered remedy). These doctrines developed along separate tracks and are not always treated consistently across jurisdictions or historical periods. A case or treatise from the nineteenth or early twentieth century may use "rescission" to describe only one of these, without flagging the distinction. Researchers working with older materials should confirm which sense is operative before drawing conclusions.
The restitutionary consequences of rescission are frequently underweighted in secondary sources. Rescission is often discussed purely as a mode of contract avoidance, but its flip side — the obligation to make restitution and the right to recover what was given — is what makes it strategically significant in litigation. Encyclopedia entries on unjust enrichment and restitution are directly relevant here.
Watch also for the distinction between rescission for breach and rescission for vitiating factors (fraud, mistake, duress). These are sometimes collapsed in older dictionaries and case annotations, but they operate differently and carry different requirements. Rescission for breach is now frequently treated under the heading of "termination" in modern contract codes, including Article 2 of the Uniform Commercial Code, which largely displaces the classical terminology in sale-of-goods contexts.
Finally, consumer protection statutes in many jurisdictions create statutory rescission rights — most notably in credit transactions and door-to-door sales — that operate on different timelines and conditions than common law rescission. These statutory variants appear frequently in twentieth-century regulatory materials and should not be assumed to track classical doctrine.

Historical Dictionary Support
Both editions of Black's define rescission consistently: "to abrogate, annul, avoid, or cancel a contract; particularly, nullifying a contract by the act of a party." The formulation is serviceable but compressed. The phrase "by the act of a party" distinguishes rescission from judicial annulment, though both editions acknowledge the term's broader application without spelling out the distinction. The second edition adds case citations without expanding the substantive definition.
What the historical dictionaries omit: the restitutionary dimension, the waiver and timeliness requirements, the equity/law divide, and the distinction between rescission for breach and rescission for vitiating factors. Researchers relying solely on the Black's formulations will have a structurally incomplete picture of how rescission operates in practice or in equity courts. Webster's 1913, by contrast, naturally gravitates toward the legislative usage (rescinding statutes and resolutions), which reflects how the term lived in general educated usage — broader and less technically freighted than the legal meaning.

Jurisdictional Note
In sale-of-goods transactions, Article 2 of the Uniform Commercial Code largely displaces common law rescission vocabulary, substituting concepts such as rejection, revocation of acceptance, and cancellation. Common law rescission doctrine remains significant in real estate, services contracts, and non-UCC commercial transactions. Jurisdictions vary on whether rescission for breach requires a "material" breach or a "total" breach and on the conditions governing restoration of performance.
