Definition
A vivor, in equity practice, is a party who survives another party to a pending suit. The term appears almost exclusively in the phrase "bill of revivor," which was the procedural mechanism used in courts of equity to revive a suit that had abated due to the death, disability, or other disqualifying event affecting one of the original parties. The surviving party — the vivor — or the successor to the deceased or incapacitated party would bring or respond to a bill of revivor to continue the litigation.
The term is not used as a standalone substantive concept; it functions as a relational label identifying the living party in contrast to the one whose death or incapacity caused the abatement.
Common Confusion
VIVOR is sometimes loosely conflated with SURVIVOR in general usage, but the terms carry different technical weight in equity procedure. A survivor is anyone who outlives another; a vivor, in the equity context, is specifically the living party to a suit — the one whose continued standing defines whether and how the proceeding may be revived. The distinction matters when reading historical chancery records: "vivor" signals a procedural posture, not merely a fact of survivorship.
Why It Matters in Research
The term appears almost nowhere as a standalone entry in historical legal dictionaries, and Rapalje & Lawrence treat it only incidentally within the entry for BILL OF REVIVOR AND SUPPLEMENT. Researchers encountering "vivor" in historical equity pleadings or chancery records should understand immediately that they are reading revival procedure, not a substantive claim.
Abatement and revival were central mechanics of pre-merger equity practice. When a complainant or defendant died mid-suit in a court of equity, the suit did not automatically continue — it abated, and a formal bill of revivor was required to bring it back to life. The vivor (the surviving original party) or the representative of the deceased party would file or respond to this bill. Without successful revival, the original suit was extinguished.
After the merger of law and equity under the Federal Rules of Civil Procedure (1938) and equivalent state reforms, the bill of revivor was replaced by motion practice — specifically what is now Rule 25 in federal practice, governing substitution of parties. Researchers working in pre-merger federal equity records, or in state courts that retained separate equity jurisdiction longer, will encounter "vivor" terminology that has no direct modern procedural equivalent. Translating these historical proceedings into modern concepts requires understanding that a bill of revivor served the function now served by a motion to substitute.
The incomplete Rapalje & Lawrence entry in the source material — which cuts off mid-sentence into an entry for BILL OF RIGHTS — underscores that historical dictionaries are unreliable guides to equity procedure terms. Researchers should treat such truncations as a prompt to consult primary chancery practice treatises rather than assuming the dictionary entry captures the full doctrinal picture.
Historical Dictionary Support
Rapalje & Lawrence address this term only within the compound entry BILL OF REVIVOR AND SUPPLEMENT, and the available text breaks off before substantive treatment is complete. This is a notable gap: the bill of revivor was a well-developed procedural device in English and American equity practice, and its associated vocabulary — including "vivor" — was in regular use in chancery pleadings through the nineteenth century.
Historical equity treatises, including those of Joseph Story and Jeremy Bentham's critics, addressed revival practice in depth, but the term "vivor" itself was typically used functionally in pleadings rather than defined with precision in doctrinal texts. What emerges from the historical record is that the term was understood by practitioners without requiring definition — a sign of how thoroughly embedded equity procedure once was in legal education and practice, and how thoroughly that knowledge has since been lost to general legal literacy.
No meaningful divergence exists across historical sources on the core meaning; the scarcity of entries rather than conflicting definitions is the research problem here.
Jurisdictional Note
Revival procedure varied by state depending on whether a jurisdiction maintained a separate court of equity and for how long. States that merged law and equity early largely abandoned bill of revivor terminology before the twentieth century. Researchers working in jurisdictions with distinct chancery courts — Delaware being the prominent surviving example — may encounter the underlying concepts in live procedural contexts, though "vivor" as a term of art has receded even there.
