Definition
A post-mortem examination of a body, conducted to determine the cause of death or to gather information about the condition of the body at the time of death. The term is used interchangeably with autopsy in most legal and medical contexts, though necropsy has historically carried a slightly broader connotation and is now more commonly used in veterinary medicine when the subject is an animal rather than a human being.
In legal proceedings, a necropsy report may serve as evidence in criminal prosecutions, wrongful death actions, insurance disputes, and public health investigations. The findings of the examining pathologist — including cause of death, manner of death, and observable injuries or disease — can be central to establishing or defeating a claim.

Common Language
Modern common usage (Wiktionary): The pathological examination of a corpse, particularly to determine cause of death.
Historical common usage (Webster's 1913): A post-mortem examination or inspection; an autopsy.
The common and legal meanings are functionally identical in their core sense. The one gap worth noting for researchers is a divergence in modern usage: in contemporary general and scientific writing, necropsy is increasingly reserved for examinations of non-human animals, while autopsy is used for humans. Legal sources — including older statutes, coroner's regulations, and court opinions — do not consistently observe this distinction, using the terms interchangeably regardless of subject.

Common Confusion
NECROPSY / AUTOPSY / POST-MORTEM EXAMINATION: These three terms describe the same procedure and are used interchangeably in most legal sources. Researchers should not infer a meaningful legal distinction based on which term a source uses. Black's 2nd Edition defines necropsy as simply "an autopsy, or post-mortem examination," confirming the equivalence. In practice, the term appearing in a document reflects the drafter's preference or professional background rather than any difference in legal effect or procedural scope.

Why It Matters in Research
This term presents a low definitional complexity but a meaningful indexing challenge. Legal sources across the Law Mind corpus — particularly older case reporters, coroner's statutes, and medical jurisprudence treatises — use necropsy, autopsy, and post-mortem examination without standardization. A search on one term may miss relevant material filed under another. Researchers working in criminal law, tort, or insurance contexts should run parallel searches across all three variants.
The modern bifurcation of necropsy (animals) versus autopsy (humans) can create confusion when reading contemporary veterinary malpractice or animal cruelty cases, where necropsy reports carry the same evidentiary function that autopsy reports carry in homicide cases. The legal standards for admissibility, chain of custody, and expert qualification apply in the same manner regardless of which term is used.
Older coroner's statutes and inquest procedures are particularly likely to use necropsy without definition, treating it as a term of art understood by the medical profession. Researchers interpreting these provisions should consult the medical jurisprudence literature of the relevant period, not just the legal dictionary shelf.

Historical Dictionary Support
Black's 2nd Edition offers a minimal entry — "an autopsy, or post-mortem examination of a human body" — that is accurate but unrevealing. It confirms equivalence with autopsy and, notably, limits the definition to human bodies, which reflects the usage conventions of the era rather than any legal rule. No historical legal dictionary in the Law Mind corpus treats necropsy as a term with independent legal significance distinct from autopsy.
Webster's 1913 likewise defers to autopsy, reinforcing that necropsy was understood as a synonym rather than a term with distinct meaning. The convergence across legal and general dictionaries from this period is consistent: the term carried no specialized legal freight beyond identifying the procedure.
What the historical sources miss is the subsequent divergence in scientific usage, which has made necropsy the preferred term in veterinary and comparative pathology contexts. This development occurred largely outside legal literature and is not reflected in law dictionaries through the mid-twentieth century.

Jurisdictional Note
Statutes governing who may order or perform a post-mortem examination, and under what circumstances, vary significantly by jurisdiction and are typically found in coroner, medical examiner, or public health codes. The term used — necropsy or autopsy — in a given jurisdiction's statute does not affect the governing legal standards, but researchers should confirm which term appears in the controlling statute to ensure accurate cross-referencing.
