Definition
"Lawfully begotten" describes a child born of parents who were legally married to one another at the time of the child's conception or birth — that is, a child born in wedlock and recognized as legitimate under law. The phrase appears most commonly in wills, deeds, and instruments of succession, typically in phrases such as "heirs lawfully begotten," "issue lawfully begotten of the body," or "children lawfully begotten." Its function was to limit inheritance or succession to legitimate offspring, as distinguished from children born outside of marriage.
Historically, legitimacy carried profound legal consequences: only lawfully begotten children could inherit property under intestacy, bear the father's name by right, and take under entails or family settlements. The phrase was therefore a term of art in conveyancing and testamentary drafting, intended to confine a gift or line of descent to the legitimate bloodline.

Common Language
Modern common usage (Wiktionary): "Begotten" is the past participle of "beget," meaning to father or produce offspring. The compound "lawfully begotten" is not a current everyday phrase; it survives mainly in archaic, religious, or legal contexts.
Historical common usage (Webster's 1913): "Beget" — to procreate, as a father; to generate. "Lawfully" — in a lawful manner; legitimately.
The gap matters here: in ordinary language, the phrase might seem simply to mean "conceived through natural means" or even "conceived within moral norms." In law, it carried a specific and enforceable technical meaning tied entirely to the marital status of the parents — not morality, not biology, but legal marriage. A child could be biologically the son of a man and still not be "lawfully begotten" by him in the legal sense if no valid marriage existed.

Common Confusion
"Lawfully begotten" is sometimes treated as interchangeable with "legitimate issue," "lawful issue," or simply "heirs of the body." As Bouvier's notes, in many contexts the qualifier "lawfully" or "lawfully begotten" adds nothing: courts reading phrases like "lawful heirs" or "heirs lawfully begotten" have treated the modifier as redundant, not as a restriction beyond what "heirs" or "issue" already implies. Researchers should not assume the presence of "lawfully begotten" invariably signals a tighter or different limitation than "issue" standing alone — context and jurisdiction govern.

Why It Matters in Research
This term is a historical evolution term more than a modern one. It was a live phrase in will-drafting, conveyancing, and entail law from the medieval period through the late nineteenth and early twentieth centuries. Researchers working in those periods will encounter it repeatedly in primary sources — wills, deeds of settlement, family trusts, chancery proceedings — and must understand both its technical meaning and its limits.
**The redundancy trap.** Bouvier's expressly flags that "lawfully" and "lawfully begotten" are often mere redundances. A researcher reading an older will or deed should not automatically infer that the drafter intended something different from "issue" simply because "lawfully begotten" appears. Courts regularly treated the phrase as surplusage.
**Entail connection.** Where the phrase appears in a limiting clause — "to the heirs of his body lawfully begotten" — courts read this as creating or confirming an entail (fee tail). The entail dimension is critical: it brings in the entire law of estates tail, the Statute De Donis Conditionalibus (1285), and later statutory reforms (including fee tail abolition in most American jurisdictions). Researchers following a chain of title or a succession dispute will need to pivot to entail doctrine immediately.
**Illegitimacy law shifts.** The underlying legal concept — that only children born in wedlock are "lawfully begotten" — was dramatically reformed across the twentieth century. Uniform Parentage Acts, constitutional equal protection decisions, and intestacy reforms in virtually every common-law jurisdiction have eroded or eliminated the distinction between legitimate and illegitimate children for most inheritance purposes. "Lawfully begotten" as operative legal language is therefore largely obsolete in modern drafting. When it appears in a modern document, it may raise interpretive questions about whether the drafter intended an anachronistic restriction or simply used boilerplate.
**Corpus navigation.** In the Law Mind corpus, this phrase will surface primarily in: (1) older chancery and equity materials dealing with family settlements and entails; (2) wills and probate records; (3) treatises on real property and conveyancing; and (4) cases interpreting limiting language in grants or devises. Cross-check against entries on LEGITIMACY, ISSUE, HEIRS OF THE BODY, and FEE TAIL to build a complete picture.

Historical Dictionary Support
Bouvier's (Byrne edition) treats the phrase efficiently and correctly. Its two key points deserve emphasis. First, in a will, a limitation using this phrase creates an entail — consistent with the common-law reading of "heirs of the body lawfully begotten" as the classic fee tail formula. Second, in expressions like "lawful heirs" or "heirs lawfully begotten," the words "lawful" and "lawfully begotten" are mere redundances that do not affect the meaning of "heir" or "issue." This is sound doctrine and reflects the weight of English and American authority.
What Bouvier's does not address: the twentieth-century dismantling of legitimacy-based inheritance distinctions, and the interpretive problems that arise when this archaic phrase appears in instruments drafted or construed under modern law. Historical dictionaries treat the phrase as stable and operative; modern research must account for the possibility that it is now either surplusage or an unenforceable anachronism depending on jurisdiction.

Jurisdictional Note
American jurisdictions have largely abolished or severely limited the legal significance of the legitimate/illegitimate distinction in inheritance law, following constitutional developments and uniform act adoption. In England and Wales, the Family Law Reform Act 1969 and subsequent legislation similarly reformed the rule. Researchers should not assume the phrase carries its historical operative weight in any modern jurisdiction without checking current statutory law.
