Definition
In Roman and civil law, ruptum (from the Latin rumpere, to break) describes a will that has been broken, annulled, or rendered void. A ruptum testamentum is a testament that was validly executed but subsequently defeated — rendered of no legal effect — typically because a later will was made, because the testator underwent a change in civil status (capitis deminutio), or because an heir who was owed a formal portion of the estate was passed over without adequate provision. The will does not fail on its face at the moment of execution; it is "broken" by a subsequent event or legal operation.
Ruptum is distinguished from other modes of testamentary failure in Roman law. A will might be void from the start (nullum or non iure factum), broken after valid execution (ruptum), or simply abandoned without revocation (destitutum or desertum). Ruptum specifically captures the category of subsequent invalidation.

Common Language
Modern common usage (Wiktionary): "Ruptum" has no independent entry as an English word. The root concept survives in English "rupture" — a breaking apart or tearing, used in both physical and figurative senses.
Historical common usage (Webster's 1913): Webster's does not list "ruptum" as an English term. "Rupture" is defined as a breaking apart, a breach, or a hernia.
The ordinary English sense of something physically broken or torn is only loosely analogous to the legal meaning. In the civil law context, ruptum is a technical term of art describing a specific juridical event — the legal invalidation of a previously valid instrument — not a physical act of destruction. A will could be ruptum while the physical document remained entirely intact.

Why It Matters in Research
Ruptum appears almost exclusively in civil law and Roman law materials. Researchers working in English common law sources will encounter it only in historical treatises drawing on Roman sources, comparative law discussions, or glossaries of Latin legal terms embedded in general law dictionaries.
The key research trap is conflating the three Roman categories of testamentary failure — nullum (void from the start), ruptum (broken by subsequent event), and destitutum (abandoned) — which historical sources do not always distinguish with care. Black's entries for ruptum cross-reference Inst. 2, 17, 3 (the Institutes of Justinian), which is the primary locus for this taxonomy. Burrill adds a further citation to Digest 28.3, which addresses specifically the ruptum will in greater detail.
For researchers tracing the civil law influence on early American or Louisiana succession law, or on Scots law and other mixed jurisdictions, ruptum is a term that may surface in foundational treatises on wills without extensive explanation, on the assumption that the reader has Roman law training. Modern succession law has largely absorbed the concept into statutory provisions governing revocation of wills, but without using the term.
The Institutes citation (2.17.3) is genuine and verifiable in standard translations of Justinian's Institutes. The Digest citation (Dig. 28.3) covers the title "De inofficioso testamento" and related matters — researchers should note that Burrill's citation points to a distinct section of the Digest dealing with wills overthrown for failure of duty to close relatives.

Historical Dictionary Support
All three source dictionaries are in essential agreement: ruptum means "broken" in the civil law, applied to a will. Black's first and second editions are nearly identical, offering the single Institutes citation. Burrill adds meaningful depth by tracing the word to rumpere, adding the full phrase ruptum testamentum, and supplying the Digest citation alongside the Institutes reference.
What the historical sources do not address is the doctrinal mechanism — precisely how or why a will becomes ruptum. For that, the researcher must go to the primary Roman sources or to treatises on Roman private law (such as those by Gaius, or modern commentators like Buckland). The dictionary entries treat ruptum as a term to be identified and located, not explained. Burrill comes closest to utility by providing both citations, giving the researcher two separate loci in the Corpus Juris Civilis to pursue.
None of the three sources distinguishes ruptum from the related categories of testamentary failure (nullum, destitutum), which is the most significant doctrinal omission for a researcher trying to use the term correctly.

Jurisdictional Note
Ruptum as a live legal term is confined to jurisdictions whose law descends from Roman or civil law sources. In Louisiana, Quebec, and mixed civil law jurisdictions, the underlying concept of will revocation by subsequent events retains civil law roots, though modern codes use vernacular statutory language rather than the Latin term. In common law jurisdictions, the concept maps roughly onto statutory revocation doctrines but the term itself has no operative force.
