Definition
A Latin phrase meaning "from the bond of matrimony." Used as a modifier to describe an absolute divorce — one that completely and permanently dissolves the marriage contract, restoring both parties to the status of unmarried persons and enabling them to remarry. Distinguished historically from divorce a mensa et thoro, which amounted only to a legal separation.
The phrase is not a standalone legal doctrine but a descriptive term, appearing most commonly in older case law, ecclesiastical court records, and treatises on domestic relations. Modern courts and statutes have largely replaced it with the terms "absolute divorce" or simply "divorce."

Common Language
Wiktionary: "Describing an absolute divorce, after which the parties may remarry."
The Wiktionary definition is accurate as far as it goes. The meaningful gap for researchers is not in the common-versus-legal meaning but in the temporal dimension: this phrase carries no force in modern statutory language and functions today almost exclusively as a historical or comparative law term. Encountering it in a source signals that the document predates or deliberately echoes older ecclesiastical or common-law divorce frameworks.

Common Confusion
A vinculo matrimonii is frequently paired with and contrasted against a mensa et thoro (from bed and board), its functional opposite. The two were the twin categories of divorce recognized under English ecclesiastical law and early American law. A mensa et thoro did not dissolve the marriage — it suspended cohabitation and marital duties while leaving the bond intact, meaning neither party could remarry. A vinculo matrimonii was the true divorce, severing the legal bond entirely.
Researchers who see the term "divorce" in pre-19th-century sources without the qualifying Latin phrase should not assume it means an absolute dissolution. The unqualified word "divorce" in early ecclesiastical and equity records often referred to the partial separation (a mensa et thoro), not the full rupture. The Latin qualifiers are the controlling language in those sources.

Why It Matters in Research
This term is a navigational signal more than a substantive doctrine. Its presence in a document almost always indicates one or more of the following: the source predates widespread divorce codification; the court had ecclesiastical or equity jurisdiction over matrimonial causes; or the writer is consciously invoking common-law categories.
In American sources, the phrase appears most frequently between the colonial period and the mid-19th century, before state legislatures systematically codified divorce law and abandoned the a vinculo / a mensa distinction in favor of statutory classifications. After roughly 1870–1900, its frequency drops sharply in American legal writing, though it persists longer in English sources and in treatises.
Researchers working in probate, inheritance, or property records should pay close attention to which type of divorce is documented. An a mensa et thoro separation left property rights and inheritance entitlements largely intact; an a vinculo matrimonii divorce could alter dower rights, intestate succession, and the legitimacy status of children depending on jurisdiction and era.
In corpus searches, the phrase may appear abbreviated, paraphrased, or translated. Search variants should include "from the bond of matrimony," "absolute divorce," and "a mensa et thoro" (to find documents that contrast the two categories). The phrase is also sometimes rendered with ligatures or variant Latin spellings in older printed sources.

Historical Dictionary Support
Black's Law Dictionary (both the 1st and 2nd editions) and Burrill's Law Dictionary are in agreement on the core meaning: a form of divorce effecting complete dissolution of the marriage contract. Burrill cites Blackstone's Commentaries (1 Bl. Com. 440) and Kent's Commentaries (2 Kent's Com. 95), which remain the most useful primary treatise sources for understanding the operation of this distinction in early Anglo-American law.
None of the historical dictionary entries elaborate on the procedural or jurisdictional context in which the term operated — specifically, the role of ecclesiastical courts in England and the shift of matrimonial jurisdiction to equity and eventually legislative courts in the American states. That institutional history is essential context the dictionaries omit.
Black's first and second editions reproduce the entry almost identically, a pattern common to basic Latin maxims and terms of art that were not contested or evolving. The stability of the entry reflects the term's status as a fixed descriptive label rather than a living legal concept.

Jurisdictional Note
In England, a vinculo matrimonii divorce required a private Act of Parliament for most of the common law period, making it extremely rare before the Matrimonial Causes Act 1857 transferred jurisdiction to secular courts. In American states, absolute divorce was available earlier by legislative or judicial decree, but the grounds and procedures varied significantly. Researchers should not assume uniform treatment across jurisdictions when working with pre-codification sources.
