Definition
"Incidents" in law carries a specific and important meaning distinct from its common plural usage: it refers to rights, duties, privileges, or obligations that attach automatically to a legal status, relationship, or estate — not by separate agreement or grant, but as a necessary consequence of the primary legal relationship itself. When something is said to be an incident of a particular right or tenure, it means it follows along with that right as an inseparable or legally inherent attribute.
The term operates most prominently in three recurring legal contexts:
1. Incidents of tenure or property: Rights and obligations that accompany ownership or possession of an estate. Under feudal and early common law, certain duties (such as homage, fealty, and relief) attached automatically to land tenure. Modern property law retains echoes of this in the form of covenants that run with the land and easements appurtenant.
2. Incidents of a legal relationship: In family law, employment law, and constitutional law, the term describes rights or consequences that flow inherently from a recognized status. The incidents of marriage, for example, include rights of inheritance, spousal privilege, and certain tax treatments. The incidents of slavery — a phrase with particular constitutional significance — describes the legal disabilities and conditions associated with bondage beyond the formal institution itself.
3. Incidents of arrest or other legal acts: In procedural and criminal law, an incident of a lawful act is a consequence or authority that the law permits or requires as part of that act. A search incident to arrest is not a separate authority but a legally attached consequence of the arrest itself.
Common Language
Modern common usage (Wiktionary): Simply the plural of "incident" — events or occurrences, typically noteworthy or disruptive ones.
Historical common usage (Webster's 1913): An occurrence or event; something that happens in connection with something else, often of secondary importance.
The legal meaning inverts the ordinary sense of subordination. In common usage, an incident is incidental — minor, secondary, or coincidental. In law, an incident is structurally attached — it is not accidental or peripheral but a defined legal consequence that the law treats as inherent to the primary relationship or status. A researcher encountering "incidents" in a legal text should not read it as meaning mere occurrences.
Common Confusion
"Incidents" is frequently misread as a near-synonym for "consequences" or "side effects." The legal term implies legal entailment — the incident is not merely a result that tends to follow but one the law recognizes as inherently belonging to the primary status or act. Similarly, "incident to" should not be confused with "incidental to." The former signals legal attachment; the latter signals mere connection or tangential relationship. Courts and statutes treat these phrases differently.
Why It Matters in Research
Researchers will encounter "incidents" most often in three high-stakes areas of the Law Mind corpus, each requiring different attention:
In constitutional law, "badges and incidents of slavery" is a term of art under the Thirteenth Amendment with significant doctrinal weight. Congress's power to reach private conduct under the Thirteenth Amendment turns substantially on whether that conduct constitutes a badge or incident of slavery. Historical sources predating the mid-twentieth century civil rights statutes will not reflect the full modern scope of this doctrine.
In family law and tax research, "incident to divorce" is a defined phrase under IRC Section 1041, controlling whether property transfers between divorcing spouses trigger recognition of gain or loss. The statutory meaning is technical and narrow; general legal dictionary definitions of "incidents" will not capture the specificity required.
In criminal procedure, "search incident to arrest" has a constitutional framework built through case law. Historical dictionary sources predate the modern Fourth Amendment jurisprudence that defines the spatial and temporal limits of this doctrine. Rapalje & Lawrence and similar sources are useful for understanding the feudal and tenure-based roots of the concept but will not assist with Fourth Amendment application.
Trap for historical research: In older sources, "incidents of tenure" refers to feudal obligations that were largely abolished in England by the Tenures Abolition Act 1660 and have no direct American equivalent. Researchers using pre-twentieth century sources should be alert to whether the "incidents" described are part of a now-abolished feudal framework or a surviving common law principle.
Historical Dictionary Support
Rapalje & Lawrence connects "incidents" explicitly to the feudal landlord-tenant relationship, describing it as a mutually protective bond in which each party was legally obligated to assist and protect the other. This framing captures the core logic: incidents were not negotiated terms but structural features of the relationship itself, imposed by the legal system rather than chosen by the parties.
Historical dictionaries generally converge on this meaning — incidents are appurtenant, attached by operation of law, and inseparable from the primary right or status without that primary right being destroyed or transformed. What older sources uniformly lack is treatment of incidents in the constitutional and statutory contexts that have given the term its modern procedural and civil rights significance. The feudal origin remains useful as a conceptual anchor, but modern legal usage has extended far beyond tenure.
