Definition
To revoke is to cancel, annul, or withdraw a previously granted right, instrument, authority, or act by the person or authority who created it. Revocation operates through the will of the revoking party — it is a voluntary act that undoes something previously done, as distinguished from avoidance by operation of law or termination by external event.
The term applies broadly across legal contexts:
1. Revocation of a will: The testator's cancellation of a prior will, either by executing a new will, by a physical act of destruction, or by operation of law (such as marriage or divorce in some jurisdictions). A will is ambulatory — it can be revoked at any time before the testator's death.
2. Revocation of a power of attorney: The principal's withdrawal of authority previously conferred on an agent. Unless the power is irrevocable (coupled with an interest), revocation terminates the agent's actual authority, though apparent authority may persist until third parties receive notice.
3. Revocation of an offer (contract law): The offeror's withdrawal of an offer before acceptance. Under general common law principles, an offer may be revoked at any time before acceptance, subject to limits such as option contracts and firm offers under the UCC.
4. Revocation of a license, permit, or professional authorization: A government or licensing body's withdrawal of a privilege it previously granted. This carries due process implications absent from private revocations.
5. Revocation of probation or parole: A court's or supervising authority's withdrawal of conditional liberty following a finding that conditions have been violated.
Common Language
Modern common usage (Wiktionary): To cancel or invalidate by withdrawing or reversing; also, to call back to mind or bring back.
Historical common usage (Webster's 1913): To call or bring back; to recall; hence, to annul by recalling or taking back; to repeal; to rescind; to cancel; to reverse anything granted by special act.
The common meaning tracks the legal meaning closely, but in ordinary usage revocation tends to feel passive or descriptive — something is simply undone. In law, the mechanics of revocation are highly context-dependent: who may revoke, how, when, with what notice, and with what effect on third parties are all substantive questions with different answers across different legal instruments. A reader encountering "revoke" in a historical legal text cannot assume the procedure or consequence without knowing the subject matter.
Common Confusion
Revoke is sometimes used interchangeably with rescind, cancel, and annul, but these are not synonyms in precise usage. Rescission typically involves mutual unwinding of a contract and implies restoration of the parties to their original positions; revocation is unilateral and prospective. Annulment often implies the act is void from inception; revocation confirms the act was valid but is now withdrawn. In contract formation, revocation applies to offers; rescission applies to executed contracts. In the will context, revocation is a term of art with specific formal requirements — a mere intent to revoke is insufficient without the required act.
Recognized Forms
/SUBTYPES
Express revocation: An explicit statement or instrument declaring a prior act cancelled.
Implied revocation: Revocation inferred from conduct or a subsequent instrument inconsistent with the prior one — most commonly, a later will that wholly disposes of the estate, which is construed to revoke an earlier will.
Revocation by operation of law: Automatic cancellation triggered by a legal event regardless of intent, such as the effect of marriage or divorce on a prior will under certain state statutes.
Revocation for cause: Used in licensing and professional regulation contexts, where the government withdraws a privilege based on misconduct or failure to meet ongoing conditions.
Why It Matters in Research
The word "revoke" appears across virtually every area of law, and the same term carries materially different procedural and substantive baggage depending on context. Researchers working in the Law Mind corpus should keep the following in mind:
Historical sources treat revocation primarily through the lens of wills, powers of attorney, and arbitration submissions. Coverage of offer revocation in the classical treatise tradition is thinner, and revocation of government-issued licenses receives almost no systematic treatment in nineteenth-century dictionaries — that doctrine is largely a twentieth-century development with constitutional due process dimensions.
For probation and parole revocation, the term's use in older materials is not coextensive with modern doctrine. The procedural protections now associated with revocation hearings are products of twentieth-century constitutional litigation and will not be reflected in pre-1970s sources.
In will research, the formal requirements for revocation vary by jurisdiction and era. Historical English practice required physical destruction or a written instrument; American states codified varying rules. A reference to revocation of a will in historical sources may not reflect the law of the jurisdiction under current research.
In contract research, watch for the term being used to describe both withdrawal of an offer and cancellation of an executed agreement — contexts that modern doctrine treats as distinct.
The Rapalje & Lawrence entry cross-references revocation of powers of attorney, arbitration submissions, and wills, which maps well to how the term operated in the nineteenth-century common law world. That framing will leave gaps for researchers dealing with statutory or regulatory revocation contexts.
Historical Dictionary Support
All five source dictionaries converge on the same core meaning: to call back, to recall, to annul by withdrawal. The Latin root (revocare) appears in Burrill and reinforces the "calling back" metaphor that runs through the historical definitions.
Anderson's Dictionary of Law is the most analytically complete of the historical sources, distinguishing revocable from irrevocable and noting that revocation is the nullification of a person's own act — an important clarification that the revoking party must be the creator of the thing revoked. This distinguishes revocation from avoidance or voidance, which may be invoked by another party.
Rapalje & Lawrence is the most practically useful of the historical sources for research navigation, listing the primary contexts (wills, powers of attorney, arbitration) with supporting authority. The cross-reference to REVOCATION suggests the compilers treated revoke as the verb form and revocation as the substantive entry deserving fuller treatment.
Black's (both editions) are characteristically brief and nearly identical, offering the definitional core without contextual elaboration. The consistency across editions confirms the term was not a site of definitional controversy in the classical period.
None of the historical dictionaries address revocation in the regulatory or constitutional sense — the procedural requirements for revoking a license or a grant of conditional liberty are entirely absent from these sources. Researchers should treat the historical definitions as accurate but incomplete for modern contexts.
Jurisdictional Note
Revocation of wills is among the most jurisdiction-sensitive applications of the term. States vary on whether divorce automatically revokes a prior will's provisions for the former spouse, whether physical mutilation (as opposed to destruction) constitutes revocation, and whether a lost will is presumed revoked. For licensing and regulatory revocation, whether the revocation requires a hearing, the standard of proof, and the availability of judicial review all turn on state administrative law.
