Definition
The party who executes a release — that is, the person who relinquishes a legal claim, right, or cause of action in favor of another. In the context of a formal release instrument, the releasor is the claimant or potential plaintiff who surrenders their right to pursue further legal action. The counterpart is the releasee, who receives the benefit of the relinquishment.
The term appears most commonly in settlement agreements, tort releases, property conveyances, and discharge-of-debt instruments. When a personal injury claimant signs a release in exchange for settlement funds, that claimant is the releasor. When a lienholder signs off on a satisfied debt, the lienholder acts as releasor.
Common Language
Modern common usage (Wiktionary): A person who releases (surrenders) a claim on an estate.
Historical common usage (Webster's 1913): One by whom a release is given.
The lay and legal meanings are unusually close here, but the legal context adds technical weight. In common speech, "releasing" a claim sounds like an informal act. In law, the releasor's act is a binding, often irrevocable relinquishment that extinguishes the underlying right — not merely a waiver that might be retracted. Researchers should not assume that because the ordinary meaning is accessible, the legal consequences are proportionally simple.
Common Confusion
RELEASOR vs. RELEASER: These are variant spellings of the same role, not distinct legal actors. Historical legal writing, including Bouvier's, favors "releasor." Modern transactional drafting sometimes uses "releaser," but the terms carry identical meaning. Researchers encountering either spelling in historical instruments should treat them as synonymous.
RELEASOR vs. GRANTOR: In property contexts, a deed of release may resemble a conveyance, and the releasor may functionally transfer an interest to the releasee. The distinction is that a grantor conveys affirmative title or interest, while a releasor relinquishes a claim or encumbrance. The legal effects can overlap, but the operative mechanism differs. In older common law practice — particularly quitclaim-adjacent instruments — this distinction was sometimes blurred in drafting.
Why It Matters in Research
Releasor is a term of relation: it only has legal significance paired with a releasee and a valid release instrument. Researchers examining historical settlement documents, release deeds, or satisfaction-of-judgment papers should verify both parties are identified and that the instrument satisfies the formal requirements for a valid release (consideration, capacity, knowing and voluntary execution) in the relevant jurisdiction and era.
In older sources, the term carries particular resonance in the context of property releases — where a releasor in a common law conveyance might be extinguishing a future interest, a dower right, or a claim under a prior deed. This usage is distinct from modern tort-settlement releases and requires attention to the conveyancing context.
One research trap: pre-twentieth-century releases were sometimes structured as sealed instruments, and the presence or absence of a seal affected enforceability. A document that names a releasor but lacks the required formalities may not have operated as a legally effective release, regardless of the parties' intent. Researchers dating releases should be alert to seal requirements and the gradual erosion of the seal doctrine across jurisdictions in the nineteenth and twentieth centuries.
For corpus researchers working with settlement agreements, note that the identity of the releasor matters in disputes over scope: courts frequently litigate whether a release signed by one releasor binds affiliated parties, assigns, or unknown claimants. The named releasor's identity and capacity are threshold questions.
Historical Dictionary Support
Bouvier's defines releasor simply as "he who makes a release" — a compact, accurate entry that treats the term as purely functional. Bouvier offers no elaboration on capacity, consideration, or the formal requirements that make a releasor's act effective, which reflects the dictionary's tendency to define parties by their role in an instrument rather than the legal standards governing their conduct.
The brevity of Bouvier's treatment signals that "releasor" was considered settled usage requiring no extended discussion. What historical dictionaries do not address — and what modern researchers must supply from treatises and case law — is the doctrine governing who may act as releasor (competency, authority to release on behalf of others, effect on co-claimants) and the circumstances under which a release may be avoided (duress, fraud, mutual mistake). These questions are absent from the historical dictionary record and must be sourced elsewhere.
Jurisdictional Note
The formal requirements for an effective release — and thus for the releasor's act to have legal consequence — vary by jurisdiction and have changed over time. Some jurisdictions historically required consideration or a seal; others recognize releases without consideration under statute. Researchers working across state lines or across historical periods should not assume uniform enforceability.
