Definition
Latin: "it dies with the person." A maxim of common law stating that certain causes of action are extinguished upon the death of either the party who held the right or the party against whom the right was asserted. When a cause of action is said to moritur cum persona, it cannot be pursued by or against the deceased's estate — the death of the relevant party ends the legal claim entirely.
The maxim applies classically to personal actions grounded in the most strictly personal wrongs: those involving bodily injury, certain dignitary torts, and actions for purely personal penalties. The reasoning is that the remedy was conceived as attached to the specific person wronged or the specific wrongdoer, not to property or transferable interests.
Two distinct applications:
1. Death of the plaintiff's decedent: The claim held by a person during life does not survive to their executor or administrator and cannot be prosecuted for the benefit of the estate.
2. Death of the defendant's decedent: The claim against a wrongdoer does not survive against that person's estate; the wrong cannot be pursued by way of judgment against assets left behind.

Common Confusion
MORITUR CUM PERSONA is frequently conflated with the separate question of whether a cause of action "survives" under a survival statute. These are related but distinct concepts. The maxim states the common law baseline — the default rule that personal actions die with the person. Survival statutes are legislative departures from that baseline, abrogating or modifying the maxim for specified categories of claims. A researcher encountering the phrase in historical sources must ask: is the source stating the common law rule, or is it already accounting for statutory modification? The two are easily blurred in older secondary literature that does not clearly distinguish baseline from exception.
The maxim is also sometimes confused with the wrongful death doctrine, but the two operate differently. Wrongful death statutes create new causes of action in survivors for their own loss; survival statutes preserve the decedent's own cause of action for the estate. Moritur cum persona, at common law, stood as a bar to both — but modern statutory reform addressed them separately and through different mechanisms.

Why It Matters in Research
This term is a navigational marker for an entire zone of common law development that was substantially reshaped by legislation beginning in the nineteenth century, most influentially Lord Campbell's Act (1846) in England and its American analogues. Any source invoking this maxim must be read with a date in hand: pre-statutory sources state it as settled doctrine; post-statutory sources may be citing it only to explain what the statute changed.
In American research, the maxim's force varies dramatically by jurisdiction and by era. Some states enacted broad survival statutes early; others retained narrower common law rules well into the twentieth century. A case applying moritur cum persona in one state in 1880 may represent a rule that was already abrogated in a neighboring state. Do not assume uniform application.
The maxim also appears in historical sources as a shorthand explanation for why executors and administrators had no standing to bring or defend certain suits. This procedural dimension — standing and capacity — is distinct from the substantive question of whether a right existed at all. Researchers should be alert to sources that use the maxim in a procedural posture without engaging the underlying substantive analysis.
The source fragment from Rapalje & Lawrence provided with this entry demonstrates a key indexing trap: the entry provided relates to the personal/real action distinction generally, not to the survival-of-actions doctrine specifically. Historical dictionaries frequently cross-reference these doctrines without clearly separating them. The personal nature of an action (as opposed to a real action) is a precondition for the maxim's application, but the two concepts are not coextensive. Not every personal action dies with the person, and the conflation in older reference works can mislead a researcher who follows cross-references without checking the specific doctrine.

Historical Dictionary Support
Rapalje & Lawrence situate the term within the broader framework of the personal/real action distinction, noting that personal actions were those brought to enforce remedies against specific persons rather than against property. This framing is consistent with the traditional doctrinal foundation of the maxim: if the action runs against the person, and the person no longer exists, the action has no object against which to run. The logic is internally coherent within the common law structure of personal and real actions, though it produces results that were widely recognized as unjust in the context of physical injury and death — a dissatisfaction that drove the survival statute reform movement.
What historical dictionaries of this period characteristically understate is the degree to which the maxim was already under active statutory erosion at the time of writing. Works from the 1880s present moritur cum persona as settled doctrine without fully accounting for the patchwork of state survival statutes already on the books in American jurisdictions. A researcher relying solely on dictionary sources from this era will obtain an accurate statement of common law principle but an incomplete picture of the operative law in any given American state.

Jurisdictional Note
At common law the maxim applied broadly across English and American jurisdictions. Virtually every American state has now modified or abrogated the common law rule by statute for most categories of personal injury and property claims, but the scope of survival varies. Some states limit survival to economic damages; others permit full survival including pain and suffering. For claims arising before a statutory effective date, the common law rule may still control.
