Definition
In law, "born" designates the point at which a person acquires legal existence as a separate human being — the moment of live birth, when a child is fully delivered from the mother and capable of independent life. This threshold matters because legal rights, protections, and property interests frequently attach at birth or depend on whether a person was "born" in the legally operative sense.
Two qualifications shape how courts and legal instruments apply the term:
1. The fiction of prior birth (en ventre sa mere): A child conceived but not yet delivered is treated as already born — that is, as a person in being — whenever doing so benefits that child. This principle applies in property law (inheritance, gifts, trusts), tort law (prenatal injury), and similar contexts. The fiction runs only in the child's favor; it is not used to disadvantage the unborn.
2. Stillbirth and non-viable birth: A child born dead, or born at so early a stage of development as to be incapable of independent life, is treated as though never born. No legal personhood attaches, no rights vest, and the birth has no operative legal effect for most purposes.
Common Language
Modern common usage (Wiktionary): Primarily the past participle of "bear" — brought into existence, delivered from the womb. Also separately, an alternative spelling of "burn" (a stream), in Scottish/Northern English dialect.
Historical common usage (Webster's 1913): "Brought forth, as an animal; brought into life; introduced by birth." Also used attributively — "a born liar," "a born matchmaker" — meaning having a characteristic by nature from birth.
The gap between common and legal usage is not in what "born" means, but in when it is deemed to have occurred. Common usage treats birth as the moment of delivery. Legal usage reaches backward (treating the unborn as already born for their benefit) and excludes forward (treating a non-viable delivery as no birth at all). The legal concept is a calibrated fiction; the everyday concept is a biological fact.
Core Elements
The legal significance of "born" depends on satisfying conditions that vary by context:
Live birth (baseline requirement): The child must be delivered and, ordinarily, show signs of independent life — breathing, heartbeat, movement. A stillbirth does not satisfy this requirement for most legal purposes.
Viability at birth: Where viability is relevant (particularly in determining whether a non-viable delivery counts as a birth), courts assess whether the infant was capable of sustaining life outside the womb, even briefly.
The en ventre sa mere exception: Where the question is whether an unborn child holds a legal interest (as a beneficiary, heir, or plaintiff), courts treat the child as born if it is later delivered alive. The fiction is conditional — it crystallizes only upon live birth.
Why It Matters in Research
Researchers encounter "born" most often as a threshold concept embedded inside larger doctrines — inheritance, citizenship, tortious injury, criminal law (fetal homicide statutes), and constitutional law. The word rarely appears alone as a term of art; it is the pivot on which related doctrines turn.
Historical sources, including both Bouvier and Anderson, are thin on "born" as a standalone entry precisely because the real action is in adjacent terms: BIRTH, CHILD, EN VENTRE SA MERE, NATUS, LEGITIMACY, VIABILITY. Researchers should not expect "born" entries to carry the full doctrine — they function as cross-reference nodes pointing elsewhere.
The en ventre sa mere fiction is old common law doctrine and appears consistently across historical dictionaries and equity cases. It is not a modern invention, but its application has expanded in some jurisdictions (particularly tort law) in ways that historical sources do not fully anticipate.
Citizenship law adds another dimension: "born" in the constitutional phrase "born... in the United States" (Fourteenth Amendment) has its own body of interpretation distinct from the property-law and common-law meanings discussed here. Researchers working on citizenship questions should treat that strand separately.
Fetal homicide statutes in many states have extended criminal liability for killing a fetus, sometimes defined without reference to the traditional "born alive" rule. These statutes mark a significant divergence from common law and from historical dictionary treatments, which uniformly anchor legal existence to live birth.
Historical Dictionary Support
Bouvier's treatment is characteristically practical: it redirects to BIRTH, then supplies the two operative rules — the en ventre sa mere fiction and the non-viable birth rule — with case support. The equity court authority cited (Paige, Ch.) reflects the doctrine's origins in chancery, where courts fashioned the born-alive fiction to protect interests of unborn children in trust and estate matters.
Anderson offers no independent analysis, cross-referencing only CHILD and NATUS, which confirms that historical legal dictionaries treated "born" as a threshold marker rather than a doctrine in its own right.
Neither dictionary addresses the constitutional dimension (birthright citizenship) or the modern statutory expansions into fetal homicide — significant gaps for any researcher working beyond the 19th-century common law context.
Jurisdictional Note
The "born alive" rule as a baseline for legal personhood is near-universal in common law systems, but its edges vary sharply by jurisdiction. Fetal homicide statutes in many U.S. states have effectively redefined legal existence to begin at fertilization or viability for criminal purposes, while civil law (tort recovery for prenatal injury) varies further. Constitutional birthright citizenship is federal and controlled by Fourteenth Amendment doctrine. Researchers should not assume uniformity across these domains even within a single jurisdiction.
