Definition
De vasto (Latin: "of waste") is the name of a common law writ that allowed a person holding an immediate estate of inheritance in reversion or remainder to bring an action against a limited-term tenant — including a tenant for life, a tenant in dower, a tenant by the curtesy, or a tenant for years — who had committed waste upon the land. The writ called upon the tenant to appear and show cause why they had committed waste and destruction upon the property, which was alleged to work to the disinheritance of the plaintiff as the future holder of the freehold.
The writ was, in essence, the procedural vehicle for the common law action of waste where the plaintiff's interest was reversionary or remainder in character. It did not address waste between co-tenants or other configurations; its operation was specifically tied to the relationship between a limited tenant in possession and a holder of the expectant fee.
Why It Matters in Research
De vasto is a purely historical term. It belongs to the pre-merger era of common law pleading and has no operative significance in modern American or English practice. Researchers will encounter it in early equity reports, in treatises on real property, and in older pleading manuals, almost always as a cross-reference to the broader doctrine of waste rather than as a subject of independent analysis.
The critical research trap is conflating the writ with the underlying doctrine. De vasto is the procedural instrument; waste is the substantive wrong. Sources that discuss "the action of waste" at common law may refer to de vasto by name only in passing, while dedicating most of their analysis to the elements of waste itself. Conversely, sources organized around forms of action will treat de vasto as its own entry while saying little about the substantive law. A researcher tracing the law of waste through historical sources should expect to navigate both registers.
In corpus sources organized by the Registers of Original Writs (Registrum Brevium) or the Natura Brevium, de vasto appears alongside kindred writs governing possession and tenure. Its placement in those registers situates it within a web of real property remedies that researchers must read together — including writs of entry, writs of right, and the separate action on the case for permissive waste — to get a complete picture of how common law courts policed tenant conduct.
Jurisdictional variation is not a meaningful concern here. The writ was abolished along with the forms of action in England and has no surviving independent procedural life in any American jurisdiction. What persists is the substantive law of waste, which has been absorbed into statutory and equitable frameworks.
Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) defines de vasto as a "writ of waste" and describes its operation consistently: it lay for the holder of the immediate estate of inheritance in reversion or remainder against the classes of limited tenant enumerated above. Both editions use the phrase "to the disinherison of the plaintiff" (ad exheredationem), which is the traditional formula carried forward from the original Latin writs and signals the nature of the plaintiff's interest — not a present possessory right, but an expectant one that waste threatened to diminish.
Rapalje & Lawrence tracks the same formulation and provides the most useful cross-referential detail, citing the Registrum Originale and the Registrum Judiciale as primary sources and directing the reader to the entry for WASTE. This redirection is informative: even in the heyday of form-of-action dictionaries, de vasto was understood as a procedural label, with the substantive content housed under waste.
None of the historical dictionaries surveyed address the distinction between voluntary and permissive waste as it bore on the availability of de vasto, nor do they discuss the equitable supplement to the writ. For those dimensions, researchers must go to Coke on Littleton or Blackstone's Commentaries, where the relationship between the forms of action and the underlying doctrine is worked out at greater length.
