Definition
A cadaver is a dead human body; a corpse. In legal contexts, the term appears most often in discussions of property rights, the right of burial, and the obligations of those who come into possession of human remains. The term is sometimes used interchangeably with "corpse" or "remains," though "cadaver" carries a clinical and anatomical connotation, frequently appearing in contexts involving medical examination, dissection, or forensic investigation.
Common Language
Modern common usage (Wiktionary): A dead body; especially the corpse of a human to be dissected.
Historical common usage (Webster's 1913): A dead human body; a corpse.
The common and legal definitions are nearly identical in their basic description. The meaningful gap lies not in what a cadaver is, but in what the law says one can do with it. Common usage treats "cadaver" as a neutral descriptive noun. Legal usage activates a body of doctrine about who has rights over a cadaver and what those rights consist of — questions the ordinary definition entirely omits.
Core Elements
The central legal principle attaching to the term is the rule cadaver nullius in bonis: no one can hold a property right in a corpse. This principle, rooted in common law, produces several downstream legal consequences that researchers will encounter repeatedly:
1. No ownership: A human body after death cannot be owned as personal property in the traditional sense. It cannot be sold, bequeathed, or seized by creditors.
2. Quasi-property rights: Despite the no-property rule, courts have recognized a qualified right — sometimes called a quasi-property right — held by the next of kin to possess the body for purposes of burial. This right is enforceable against interference but is not property in the full commercial sense.
3. Duty of burial: The law imposes obligations on certain persons (surviving spouse, next of kin, sometimes an executor) to arrange for the burial or lawful disposition of the cadaver. This duty runs alongside the quasi-property right.
4. Tortious interference: Wrongful handling, mutilation, or withholding of a cadaver can give rise to tort liability, often framed as interference with the right of burial or negligent infliction of emotional distress.
Why It Matters in Research
Researchers working in early common law sources will encounter cadaver primarily in two contexts: the ecclesiastical law of burial and the criminal law governing treatment of the dead (e.g., body-snatching, which generated significant 19th-century litigation). The phrase cadaver nullius in bonis is the doctrinal anchor — tracking it through case law reveals how courts managed the tension between the no-property rule and the practical need to give next of kin enforceable rights against those who disturbed or withheld remains.
A significant research trap: the no-property rule has been substantially modified by statute in most modern jurisdictions. Uniform acts, anatomical gift legislation, and state burial statutes have layered positive rights and duties over the common law baseline. A researcher relying only on the Black's definition or pre-20th-century cases will miss this statutory transformation. The common law rule describes the historical baseline; it does not describe the current state of the law in most U.S. jurisdictions.
The term also appears in modern forensic and evidentiary contexts — cadaver dogs, cadaver decomposition, chain of custody for human remains in criminal prosecutions — where the legal issues concern evidence rules and criminal procedure rather than property or burial rights. These are distinct research tracks that happen to share the same term.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) defines cadaver as "a dead human body; a corpse" and immediately pivots to the maxim cadaver nullius in bonis, citing Coke's Institutes (3 Co. Inst. 110), Blackstone's Commentaries (2 Bl. Comm. 429), and Griffith v. Railroad Co. This is characteristic of the era's dictionary treatment: a minimal nominal definition followed by the operative legal rule. The entry does not address quasi-property doctrine, tortious interference, or statutory modification — all of which developed more fully in 20th-century case law. Researchers should treat the Black's entry as a correct but incomplete statement of the law even as of its own period; by the time quasi-property rights were firmly recognized in American courts, the 2nd edition was already dated.
Webster's 1913 and the Black's definition are identical at the descriptive level, which confirms that the legal and ordinary meanings of the word itself were never in dispute. The legal content lies entirely in the doctrine attached to the term, not in the term's meaning as a word.
Jurisdictional Note
Anatomical gift statutes (modeled on the Uniform Anatomical Gift Act, with multiple revision cycles) and state burial and disposition statutes have significantly altered the common law framework across U.S. jurisdictions. Some states expressly recognize a property right in donated cadavers or cadaver parts for medical and research purposes, directly contradicting the common law nullius in bonis rule. Researchers should always identify the applicable state statutory scheme before relying on common law doctrine.
