Definition
Custody carries two distinct legal meanings that arise in entirely separate areas of law. Researchers should be careful not to assume the term is operating in one context when it may be operating in the other.
1. Criminal and procedural custody. The detention or restraint of a person by lawful authority; actual imprisonment. A person is "in custody" when their freedom of movement is meaningfully curtailed by state authority. This encompasses formal arrest and incarceration but extends to any significant deprivation of liberty short of complete freedom. The question of whether someone is "in custody" has constitutional significance, particularly in the context of interrogation and Miranda rights.
2. Parental and guardianship custody. The legal right and responsibility to care for a person who cannot care for themselves, most commonly a minor child. This meaning subdivides further into legal custody (decision-making authority over the child's upbringing, education, health, and welfare) and physical custody (where the child lives and who provides day-to-day care). These two components may be held by the same person or split between parties.
3. Custodial possession of property. The care, charge, and keeping of a thing on behalf of another, without any adverse claim of ownership. A servant, bailiff, or officer who holds another's property for safekeeping exercises custody in this sense. This is distinct from legal possession, which implies a fuller set of rights against third parties.

Common Language
Modern common usage (Wiktionary): "The legal right to take care of something or somebody, especially children"; also "the state of being imprisoned or detained, usually pending a trial."
Historical common usage (Webster's 1913): "A keeping or guarding; care, watch, inspection, for keeping, preservation, or security"; also "state of being guarded and watched to prevent escape; restraint of liberty; confinement; imprisonment."
The common and legal meanings overlap more than usual here, but the gap worth noting is this: in ordinary speech, "custody" in the child context often implies simple physical care or possession of the child. In law, custody is a bundle of rights and duties that can be divided, shared, conditionally granted, and judicially modified. The assumption that whoever the child lives with automatically holds "custody" in the legal sense misreads how modern family courts allocate the term.

Common Confusion
Legal custody vs. physical custody. These are frequently collapsed in casual usage and even in older judicial opinions. Legal custody is the authority to make major decisions about a child's life. Physical custody is the right to have the child reside with you. A parent can hold joint legal custody while the other parent holds primary physical custody. Conflating the two creates serious errors when reading custody orders or historical case law that predates the formal distinction.
Custody vs. detention vs. arrest. In criminal procedure, these terms occupy related but distinct positions. Arrest requires formal invocation of legal authority. Detention may be brief and investigatory. Custody is the operative term for constitutional purposes — particularly under Miranda — and may arise without a formal arrest. Older sources sometimes treat the terms as interchangeable in ways modern doctrine does not permit.
Custody vs. possession (property law). Anderson's Dictionary draws the distinction precisely: custody is charge to keep and care for the owner, subject to the owner's direction and without adverse right. Possession implies a broader legal relationship with the thing itself. A warehouse employee has custody of stored goods; a buyer under a sales contract has possession.

Why It Matters in Research
The two primary meanings — criminal detention and parental rights — appear in entirely separate bodies of law, separate court systems, and separate indexes. A search across historical sources for "custody" without limiting context will retrieve results from both, and the results will not be obviously distinguishable in older digest headings.
In the criminal context, the meaning of custody has expanded significantly over the twentieth century. Historical sources reflect a definition rooted entirely in physical imprisonment — the Pennsylvania cases cited by Black's and Bouvier's held that custody meant nothing less than actual imprisonment. Modern constitutional doctrine, developed through case law the historical dictionaries cannot reflect, extends "custody" to encompass a broader range of liberty restraints. Researchers reading pre-twentieth-century sources should be alert to this contraction of the concept.
In the family law context, the major transformation is the formal split between legal and physical custody. This distinction is largely a product of late-twentieth-century statutory reform and judicial practice. Historical sources — including all six dictionaries surveyed here — treat custody as a unitary concept, generally vested in the father as a matter of common law. They do not anticipate joint custody, the best-interests-of-the-child standard as a freestanding doctrine, or the equal standing of mothers. Researchers using nineteenth-century sources to understand custody law should treat them as reflecting a legal regime that has been substantially replaced, not merely modified.
The property custody meaning appears regularly in commercial law, bailment, and estate administration contexts. It is easy to overlook because it is grammatically identical to the other uses. When reading sources on property, trusts, or agency, confirm which meaning is operative before drawing doctrinal conclusions.
The Law Mind corpus connects custody across family_68, family_69, and family_76 for the child custody context. Researchers working on criminal procedure custody questions should look beyond the family law entries.

Historical Dictionary Support
The historical dictionaries converge on two core meanings: physical imprisonment and the care or keeping of persons or property. Black's (both editions), Bouvier's, Anderson's, and Burrill's all treat these meanings as settled. Bouvier's is the most explicit in grounding the imprisonment meaning in case authority, citing Pennsylvania decisions for the proposition that custody means "nothing less than actual imprisonment." This was a real doctrinal position in nineteenth-century jurisprudence, not merely rhetorical emphasis.
Anderson's Dictionary offers the most analytically useful treatment of the property custody meaning, distinguishing it from legal possession with a precision the other sources lack. The characterization of custody as "charge to keep and care for the owner, subject to his direction, and without any adverse right, which every servant possesses with regard to goods confided to his care" is a formulation that remains conceptually sound and useful for historical research on bailment and agency.
On parental custody, the historical dictionaries reflect the common law default without examining it critically. Bouvier's notes that the father's rights include authority over children and the right to delegate to tutors — a framing that assumes paternal custody as the norm requiring no justification. The mothers' rights dimension is absent. This is not an omission by the editors so much as an accurate reflection of the law they were reporting, but it is a significant gap for researchers working on custody disputes involving mothers or on the evolution of the best-interests standard.
Burrill's is the briefest of the sources on this term and adds little beyond confirming the core definitions. The note in Burrill's regarding "custom" as toll or tribute under "customs" is a separate term and should not be treated as part of the custody entry.

Jurisdictional Note
Child custody law is almost entirely state-governed in the United States, and statutory frameworks vary considerably. Most states have adopted some version of the Uniform Child Custody Jurisdiction and Enforcement Act, which governs which state's courts have authority to issue and modify custody orders — a jurisdictional question with significant practical consequences in interstate disputes.
