Definition
An archaic legal term referring to children born of a couple who subsequently marry one another. Under the civil law tradition, such children were considered legitimate by virtue of the subsequent marriage. Under the common law, however, the subsequent marriage of the parents did not retroactively legitimize children born before the ceremony. The term appears in older English legal writing as a designation for this class of children, whose legal status turned entirely on which legal system governed the question.
Common Language
Modern common usage (Wiktionary): Obsolete form of "pannier" — a basket, typically one carried by a beast of burden or worn on the hips.
Historical common usage (Webster's 1913): Refers to pannier in its basket sense; the 1913 edition notes "panier" as an obsolete variant spelling.
The common and legal meanings share no meaningful relationship. The legal term is a term of art from civil law vocabulary applied to questions of legitimacy; it has no connection to the basket sense of the word.
Common Confusion
"Panier" as a legitimacy term should not be confused with "spurious" children (those born of adulterous or incestuous unions) or simply "illegitimate" children in the general sense. The defining feature of a panier child is the specific factual predicate — birth before, and the subsequent marriage of, the natural parents — which gave rise to legitimation under civil law but not at common law. Researchers may also encounter "legitimation by subsequent marriage" as the functional doctrine without use of the term "panier" at all, particularly in later sources.
Why It Matters in Research
This term is nearly extinct in modern legal writing and will appear almost exclusively in older secondary sources, treatises drawing on civil law roots, and ecclesiastical or probate records where legitimacy of heirs was contested. Researchers working in succession law, inheritance disputes, or family law history should be aware that the term signals a civil law frame of reference. English common law courts did not accept the civil law rule of legitimation by subsequent marriage, so a source using "panier" is almost certainly drawing on continental or canonical authority, or making a comparative point.
The divergence between civil and common law treatment of these children was a live controversy in English legal history and carries over into American jurisdictions that trace their family law roots to civil law sources (notably Louisiana). A researcher encountering "panier" in a historical American document should immediately ask which legal tradition the author was applying.
The term may also appear in discussions of the Scottish and canon law rules, both of which were more receptive to civil law legitimation doctrine than English common law.
Historical Dictionary Support
Both editions of Black's Law Dictionary cover "panier" briefly, citing Jacob's Law Dictionary as authority. The entry in both editions is nearly identical, noting that children designated by this term were legitimate under the civil law but not under the common law. Neither edition provides substantial elaboration, and neither edition defines the precise conditions required (i.e., that the parents subsequently marry) with any more detail than the bare civil/common law contrast. The reliance on Jacob suggests the term was already archaic by the time Black compiled his dictionary and was being preserved as a historical reference rather than an active term of practice.
Neither edition addresses how American courts handled the question, and neither links the term to the broader doctrine of legitimation. Researchers should treat both entries as a starting point for locating older civil law and canonical sources rather than as a complete statement of the doctrine.
Jurisdictional Note
Louisiana, with its civil law heritage, historically followed the civilian rule that subsequent marriage of the parents could legitimate previously born children. Most common law American jurisdictions did not adopt this rule by default, though many eventually enacted statutes permitting legitimation by subsequent marriage without using the term "panier."
