Definition
A permanent trespass is a trespass consisting of repeated wrongful acts of the same character, committed on successive days, that are renewed or continued from day to day in such a way that the harm inflicted on each individual day cannot be meaningfully distinguished from the harm inflicted on any other day. Taken together, these recurring acts constitute a single, indivisible wrong rather than a series of separate, discrete injuries.
The defining feature is continuity: the wrongful conduct recurs with sufficient regularity and sameness that it is treated as one ongoing wrong rather than as multiple independent trespasses. Because the daily injuries merge into an aggregate, the pleading rules applicable to permanent trespass differ from those governing a one-time or readily distinguishable series of trespasses.

Common Confusion
PERMANENT TRESPASS vs. CONTINUING TRESPASS: These terms are often used interchangeably in older authorities, and the confusion is understandable — both involve trespassory conduct that extends over time. The critical distinction is one of legal character, not duration. A continuing trespass is a single wrongful act (such as placing an encroaching structure on another's land) that persists without repetition; the wrong is ongoing because the original act has never been undone. A permanent trespass, by contrast, arises from a repeated series of fresh acts, each of the same nature, that are renewed day after day. The practical consequence matters for limitations and pleading: a continuing trespass may give rise to a single cause of action, while a permanent trespass laid with a continuando treats the recurring acts as a cumulative, indivisible wrong for purposes of the declaration. Researchers using 19th-century sources should not assume the terms carry the same meaning across authorities.

Why It Matters in Research
Researchers encounter permanent trespass most often in historical property and tort materials, where it appears as a pleading concept tied directly to the common-law form of action. The term has limited independent life in modern civil practice — contemporary courts tend to fold the analysis into broader discussions of continuing nuisance, trespass to land, or the discovery rule as applied to ongoing property injuries. When tracing a modern dispute about recurring encroachments, flooding, or repeated entry, researchers working backward into 19th-century precedent will find the permanent trespass / continuing trespass distinction doing work that modern doctrine handles through different mechanisms.
The pleading connection is the most practically important thread. Because the daily injuries in a permanent trespass cannot be separated, the declaration was traditionally laid with a continuando — a pleading device that covered a range of dates rather than a single act. Researchers who see continuando in an old declaration or indictment should recognize it as a signal that permanent or repeated trespass is in play, and cross-reference accordingly.
Limitations traps: Courts in different eras treated the accrual question for recurring trespasses inconsistently. Some held that the statute of limitations ran from the first wrongful act; others held that each day's act generated a fresh cause of action. Knowing which characterization a court applied (permanent and indivisible vs. daily and separate) is essential to understanding how a historical case was decided on limitations grounds. Do not assume modern accrual doctrine maps cleanly onto historical permanent trespass analysis.
The term "permanent" is also a false friend. In modern property law, "permanent" trespass sometimes appears in condemnation and inverse condemnation contexts to describe a government intrusion that is irreversible in character — a usage that is analytically distinct from the historical pleading sense covered here. Researchers crossing between tort and takings materials should confirm which sense is operative.

Historical Dictionary Support
Black's Law Dictionary and Bouvier's Law Dictionary are in close agreement on the core definition, with Bouvier offering somewhat greater precision: the trespasses must be of one and the same kind, committed on several days, capable of renewal or continuation, actually renewed or continued, and the particular injury on each day must be indistinguishable from that on any other. Black's, drawing on Blackstone's Commentaries (Book 3), frames the same concept as acts of the same nature that are renewed or continued from day to day, making up one indivisible wrong. Both sources confirm the continuando connection.
Rapalje & Lawrence is less helpful here, directing the reader to CONTINUENDO and TRESPASS without supplying an independent definition of permanent trespass. This cross-reference pattern is itself instructive: it confirms that permanent trespass was understood primarily as a pleading category rather than a freestanding substantive tort, and that its meaning was inseparable from the mechanics of the continuando.
What the historical dictionaries collectively do not address is the boundary question — at what point a series of repeated trespasses fails to qualify as permanent because the daily injuries are distinguishable, or because the acts are not sufficiently uniform. That analysis was worked out in cases rather than dictionaries, and researchers will need to go to the reporters for it.

Jurisdictional Note
American courts adopted the English permanent trespass framework but applied it unevenly, particularly on the limitations question. Kentucky materials (see the 12 Bush reference in Rapalje & Lawrence) reflect one strand of American treatment. Researchers working in any specific jurisdiction should verify locally how courts characterized recurring trespasses for limitations and pleading purposes, as the answers varied.
