Definition
Utor de son tort (from the Law French meaning "executor of his own wrong") is a person who, without lawful authority — neither appointed by the will nor by a court — intermeddles with the goods or estate of a deceased person in a manner that exposes them to the duties and liabilities of an executor. By acting as though they were an executor without being one, such a person is treated by law as if they had assumed that office, and may be held accountable accordingly.
The doctrine operates as a form of legal accountability: a stranger who takes possession of a decedent's assets, pays debts, collects on obligations, or otherwise administers the estate without authority cannot later disclaim responsibility by pointing to the absence of a formal appointment. Their conduct binds them. They may be sued by creditors of the estate, and assets they have received or disposed of may be traced and recovered.

Common Language
This term has no meaningful presence in ordinary English. It is pure Law French legal vocabulary, retained in English legal usage as a technical term of art in the law of executors and estate administration. There is no Wiktionary entry and no Webster's 1913 entry for this phrase. A researcher encountering it for the first time should treat it as an entirely legal concept with no lay equivalent.

Common Confusion
UTOR DE SON TORT vs. EXECUTOR / ADMINISTRATOR: The confusion most likely to mislead a researcher is treating an executor de son tort as a species of executor or administrator. They are not. A lawfully appointed executor derives authority from the will; an administrator derives authority from the court. An executor de son tort derives authority from neither — their obligations arise not from appointment but from their own unauthorized conduct. The legal consequences may overlap, but the source of liability is entirely different.
UTOR DE SON TORT vs. TRUSTEE DE SON TORT: A parallel doctrine applies in equity to persons who intermeddle with trust property without authority, exposing themselves to the liabilities of a trustee. These are related but distinct doctrines. A researcher working in equity contexts should distinguish between the two.

Why It Matters in Research
This term appears almost exclusively in historical sources — English ecclesiastical court records, early American probate proceedings, and nineteenth-century treatise literature on executors and administration. Researchers working in pre-twentieth-century probate and estate law will encounter it with some regularity; researchers in modern materials will encounter it rarely, as most jurisdictions have absorbed the underlying doctrine into statutory estate law without preserving the Law French label.
The source material provided by Bouvier's appears to have been misdirected: the text supplied under this heading describes special executors and executors to the tenor, not executor de son tort as such. This is a meaningful research trap. When consulting historical dictionaries — including Bouvier's — on related executor concepts, entries may bleed into one another, and readers should verify they are reading the entry intended. Cross-checking across editions of Bouvier's is advisable.
The doctrine itself matters for researchers examining creditor claims against estates, priority disputes among those claiming to administer an estate, and the liability of persons who receive estate property informally. In early American cases, the executor de son tort concept was invoked where family members, business partners, or neighbors took charge of a decedent's affairs before formal administration was opened. Understanding the doctrine is essential to tracing asset flows in such cases.
The term also surfaces in English ecclesiastical jurisdiction materials, where the prerogative courts had authority over testamentary matters. Researchers consulting those sources should be aware that the doctrine was well-developed in English ecclesiastical law before American courts adopted it.

Historical Dictionary Support
Bouvier's Law Dictionary treats the concept within its broader discussion of executors, though the supplied text appears to have captured a passage describing special executors and executors to the tenor rather than the executor de son tort entry itself. This is consistent with a known organizational challenge in Bouvier's: the various executor subtypes are treated in proximity, and the distinctions among them — appointed executor, special executor, executor to the tenor, and executor de son tort — can blur across editions.
The core principle that historical dictionaries consistently preserve is this: the wrongdoer is estopped from denying the office they have effectively assumed. By intermeddling, they accept the burdens that accompany the benefits. Historical sources are reliable on this core principle. Where they are less reliable is on the precise scope of what conduct constitutes sufficient intermeddling — a question that received varying treatment across English ecclesiastical courts and early American probate courts, and which historical dictionaries tend to resolve by example rather than rule.
No major historical dictionary — including Bouvier's in its various editions — provides a comprehensive treatment of the evidentiary and procedural dimensions of executor de son tort claims. Researchers should supplement dictionary sources with treatise literature, particularly nineteenth-century treatises on the law of executors.

Jurisdictional Note
The doctrine was well established in English law and carried into American common law jurisdictions, but its continuing vitality varies. Many states have replaced or significantly displaced it through probate codes that define who may administer an estate and what liability attaches to unauthorized administration. Researchers should not assume the Law French label or its precise common law contours survive in any given modern jurisdiction without checking applicable statutes.
