Definition
The act of withdrawing, canceling, or making void something previously granted, authorized, or conferred. Revocation terminates the legal effect of the prior act as of the moment of revocation, leaving intact whatever was done under it before that point unless the revocation is given retroactive effect by law or agreement.
Revocation operates across several distinct legal contexts, each governed by its own rules:
1. Contracts and offers. An offeror may revoke an offer at any time before the offeree's acceptance, provided the revocation is communicated before acceptance occurs. Once accepted, an offer merges into a contract and can no longer be revoked unilaterally.
2. Wills and testamentary instruments. A testator may revoke a will during their lifetime by executing a later will, or by a physical act — burning, tearing, canceling, or obliterating the document — performed with intent to revoke (animo revocandi). Revocation restores the legal landscape to whatever it would have been without the revoked instrument; if no prior valid will exists, the estate passes by intestacy.
3. Agency and powers of attorney. A principal may revoke an agent's actual authority at will, subject to any contractual obligations. A power coupled with an interest is an exception — it cannot be revoked unilaterally because the authority was granted to protect the agent's own interest in the subject matter.
4. Licenses, permits, and public grants. A government body may revoke a license, permit, or franchise when the holder violates conditions of the grant, subject to procedural due process where a protected property or liberty interest is at stake.
5. Probation and parole. A court or supervising authority may revoke an individual's probation or parole upon finding a violation of conditions. Because liberty is at stake, revocation proceedings carry procedural protections established by constitutional due process doctrine, though they are less extensive than full criminal trial protections.
6. Continuing guaranties. A guarantor on a continuing guaranty may revoke prospective liability by giving notice to the creditor, although revocation does not extinguish obligations already incurred under the guaranty before the notice.

Common Language
Modern common usage (Wiktionary): An act or instance of revoking.
Historical common usage (Webster's 1913): The act of calling back, or the state of being recalled; the act by which one, having the right, annuls an act done, a power or authority given, or a license, gift, or benefit conferred; repeal; reversal.
The common meaning is accurate as far as it goes, but it obscures a critical legal distinction: revocation ordinarily operates prospectively only, preserving the legal effects of the prior act up to the moment of revocation. In ordinary speech, "canceling" something often implies erasure; in law, revocation rarely unwinds completed transactions. A researcher who imports the lay sense of total nullification into legal sources will misread both the doctrine and the cases applying it.

Common Confusion
Revocation is frequently confused with rescission and repudiation, but these are distinct concepts. Rescission voids a contract from its inception — ab initio — as though it never existed, often on grounds such as fraud, mutual mistake, or failure of consideration. Revocation, by contrast, terminates something going forward without necessarily disturbing what came before. Repudiation refers to one party's anticipatory refusal to perform a contractual obligation still in the future. In offer-and-acceptance analysis, only revocation applies to the act of withdrawing an offer; the other terms should not be imported into that analysis.
Revocation should also be distinguished from lapse, which occurs when an offer expires by the passage of time or the occurrence of a terminating condition, without any affirmative act by the offeror.

Recognized Forms
/SUBTYPES
General revocation: A broad revocation of all prior acts, authorities, or instruments of a given class. Common in the execution of a new will that purports to revoke all prior wills and codicils.
Special revocation: Revocation of a specific grant, instrument, or authority, leaving others unaffected.
Revocation by act of the party: An intentional, voluntary revocation executed by the person holding the right — as opposed to revocation by operation of law.
Revocation by operation of law: Revocation that occurs automatically upon a legally defined event, without any affirmative act by the grantor. Marriage, divorce, or the birth of a child after execution of a will may revoke it in whole or in part under applicable statute, depending on jurisdiction.
Implied revocation: Revocation that arises from conduct or a later instrument plainly inconsistent with the continued existence of the earlier one, even where no express revocation is stated.

Why It Matters in Research
The term appears in bodies of law that rarely cite each other, and researchers risk importing doctrine from one context into another where it does not apply. The rules for revoking a will are entirely distinct from the rules for revoking an offer, which are distinct again from the constitutional requirements governing revocation of probation or parole. Always identify which legal context controls before applying any authority.
In historical sources, revocation of wills receives the most sustained doctrinal attention, and the procedural requirements for valid physical revocation — particularly what acts qualify as "canceling" or "obliterating" under successive versions of the Statute of Frauds and later Wills Acts — shifted over time and varied between English and American jurisdictions. Sources that cite the Statute of Frauds on this point may not reflect the law in American states that enacted their own statutory formulations.
For offer revocation in contracts research, the historical common law rule of free revocability before acceptance hardened over time, and the firm offer exception (codified in UCC Article 2 for merchants) represents a significant departure that older sources predate entirely. Sources from before the mid-twentieth century should be read against modern statutory modifications.
In the agency and powers context, the "power coupled with an interest" exception is a persistent source of confusion in older case law, where courts did not always apply the distinction consistently. Burrill's cross-reference to judges' orders signals that historical usage was broader than modern doctrine, and researchers should not assume terminological uniformity across eras.
Probation and parole revocation is almost entirely a twentieth-century doctrinal development. Historical dictionaries are of little use here; the constitutional framework was established by Supreme Court decisions in the 1970s and refined thereafter. Researchers working on this subject should move directly to procedural due process doctrine rather than relying on general revocation principles from the treatise tradition.

Historical Dictionary Support
The historical sources converge on a core definition: revocation is the calling back of something granted, making void a deed or authority that previously had legal existence. Black's (both editions) and Burrill adopt this framing, and all note the general/special distinction drawn from Coke. This baseline is reliable for understanding pre-twentieth century usage.
Bouvier provides the most detail on will revocation, tracking the precise statutory language of the Statute of Frauds and the English Wills Act — an important reminder that the permissible modes of physical revocation were creatures of specific statutory text, not common law inference. Bouvier's reference to animo revocandi (intent to revoke) captures an element the other sources understate: the physical act alone is insufficient; intent must accompany it.
Burrill's note that revocation "is also sometimes applied in practice, as to judges' orders" reflects a broader historical usage that has since narrowed. Modern doctrine does not typically describe a court's modification or vacation of its own order as a "revocation," preferring "vacatur" or "modification." Researchers encountering the term in historical judicial opinions should not assume it carries the same doctrinal weight as revocation of a private instrument.
What the historical dictionaries largely omit: the constitutional dimension of revocation in the criminal supervision context, the UCC's firm offer rule, and the procedural architecture governing license and permit revocation under administrative law. These are twentieth-century developments and should not be expected from these sources.

Jurisdictional Note
Will revocation rules vary significantly by state statute. The modes of physical revocation, the effect of divorce or subsequent marriage on a prior will, and the doctrine of dependent relative revocation (which may restore a prior revoked will when the revocation was conditional on the validity of a later instrument) all depend on state-specific enactments and case law. Researchers should identify the applicable jurisdiction and governing statute before relying on any general statement of will revocation doctrine.
