Definition
A putative marriage is a marital union that is legally invalid due to an impediment — such as a prior existing marriage, a prohibited degree of kinship, or failure of legal capacity — but that was entered into in good faith by at least one of the parties, who genuinely believed the marriage to be valid at the time of its solemnization. Because at least one party acted in honest ignorance of the defect, courts in jurisdictions that recognize the doctrine extend certain legal protections to that party (and often to children of the union) that would otherwise be unavailable to participants in a void or voidable marriage.
The doctrine is protective rather than validating: a putative marriage is not transformed into a valid marriage. Instead, the good-faith spouse — the putative spouse — is treated as though married for limited purposes, including property division, inheritance rights, and in some jurisdictions spousal support, until the impediment is discovered or the relationship ends.
Common Language
Wiktionary: "A marriage that is invalid because of an impediment or a lack of consent, but entered into in good faith by at least one of the parties and follows the form established by canon law."
The ordinary sense of "putative" — meaning supposed, reputed, or commonly believed to be — tracks closely to the legal meaning here. The gap worth flagging is this: in common usage "putative" often implies mere assumption or reputation without particular legal consequence (as in "putative father," used loosely). In family law, however, the putative marriage doctrine carries a formal, operative legal significance. Good faith is not merely descriptive; it is a threshold requirement that triggers specific legal protections. A researcher using "putative marriage" loosely as a synonym for "informal" or "unregistered" marriage will misread historical and modern sources alike.
Core Elements
Three elements must concur for the putative marriage doctrine to apply:
1. A ceremonial or formal solemnization. The parties must have gone through a marriage ceremony or followed the recognized form of marriage. A purely informal cohabitation arrangement, even with subjective intent to marry, does not qualify.
2. A legal impediment rendering the marriage void or voidable. The marriage must in fact be legally defective — bigamy, consanguinity, lack of capacity, or similar bar. Without an actual impediment, the marriage is simply valid, and the doctrine is irrelevant.
3. Good faith on the part of at least one party. One spouse must have had an honest, reasonable belief in the validity of the marriage at the time of the ceremony. Good faith ends upon discovery of the impediment; protections generally do not extend beyond that point. The impediment need not be known by both parties — the doctrine protects whichever party acted in genuine ignorance.
Why It Matters in Research
The putative marriage doctrine is jurisdictionally uneven, and this is the most important navigational point for corpus researchers. The doctrine has deep roots in canon law and civil law traditions, which means it is well-established in Louisiana and California — both of which codified it — but has been adopted patchily or not at all in common law jurisdictions. Researchers working across state lines must not assume that a result reached in a California putative spouse case travels to a common law state.
Historical sources present a further trap: Bouvier and early editions of Black's describe the doctrine in terms drawn directly from ecclesiastical and civil law sources, including references to canon law form requirements. These descriptions may not map onto modern statutory codifications, which vary in what they protect (property rights, inheritance, support) and whether children of the union receive independent protection.
The relationship between putative marriage and common law marriage is a recurring source of confusion in the corpus. In jurisdictions that recognize both doctrines, they can overlap factually, but they rest on different foundations: common law marriage does not require a ceremony, while putative marriage does. Researchers analyzing historical family law disputes should identify which doctrine is actually at issue before drawing analogies across cases.
The doctrine also intersects meaningfully with conflict of laws problems. A marriage celebrated in one state that is void there may still trigger putative spouse protections in a second state where the couple later resided. The Law Mind Encyclopedia entry on Recognition of Foreign and Interstate Marriages is directly relevant to this research path.
Historical Dictionary Support
Both Black's and Bouvier's define the putative marriage in consistent terms — a marriage forbidden by law but contracted in good faith and ignorance of the impediment by at least one party. Bouvier is more detailed, explicitly requiring three concurring circumstances: bona fides, ignorance of the impediment at the time of the marriage (not merely afterward), and continuing good faith. The emphasis on the temporal dimension — ignorance at the moment of solemnization — is a point modern sources sometimes understate, and Bouvier's formulation is useful for anchoring historical analysis.
Black's treatment is compressed but aligns with Bouvier's on the substantive elements. Neither historical source provides sustained analysis of what protections attach — their entries are definitional rather than operational. For the legal consequences of putative marriage status, researchers will need to move beyond these dictionary entries into treatise and case law sources. The historical dictionaries are reliable on the structure of the doctrine but largely silent on its remedial scope.
Both sources reflect the doctrine's origins in ecclesiastical law, which treated the good-faith spouse as deserving protection from forfeitures that strict application of the impediment would otherwise impose. This moral-equitable rationale continues to animate modern applications.
Jurisdictional Note
Louisiana and California have codified the putative marriage doctrine by statute, making it the most reliably documented jurisdiction for research. Many other states have not adopted it by statute and courts vary in whether they apply it through equity or common law principles. In jurisdictions that recognize neither putative marriage nor common law marriage, a void marriage generally confers no spousal rights regardless of good faith.
