Definition
Putative means reputed, supposed, or commonly regarded as something — applied to a status, identity, or relationship that is accepted as real by common belief or apparent circumstances, but which has not been legally established or which may rest on a factual or legal defect. The word functions as a qualifier, signaling that the legal designation it modifies is assumed or claimed rather than formally adjudicated.
In modern family law, the term appears most consistently in two high-stakes contexts:
1. Putative father: A man alleged or commonly believed to be the biological father of a child born outside of marriage, but whose paternity has not been legally established. Putative father status carries procedural consequences — particularly regarding notice of adoption proceedings and the right to assert parental rights — that differ significantly from legally adjudicated paternity.
2. Putative marriage: A marriage that is void or voidable due to a legal impediment (such as a prior undissolved marriage or a prohibited degree of relationship), but which was entered into in good faith by at least one party who was unaware of the impediment. The doctrine preserves certain legal consequences of marriage — most commonly property rights and spousal support claims — for the good-faith party, even though the marriage is invalid.
More broadly, putative can modify any legal status or relationship: putative owner, putative creditor, putative spouse, putative heir. In each case, the word flags that the person holds the described position by reputation or reasonable belief, not by confirmed legal right.

Common Language
Modern common usage (Wiktionary): Commonly believed or deemed to be the case; generally assumed; accepted by supposition rather than proof; alleged, purported, or ostensible.
Historical common usage (Webster's 1913): Commonly thought or deemed; supposed; reputed — illustrated with the example "the putative father of a child."
The gap between common and legal meaning is narrower here than with many legal terms, but it matters at the margins. In ordinary English, "putative" can describe almost any unconfirmed assumption. In law, the word does specific procedural and doctrinal work: a putative father has defined rights and registration obligations; a putative spouse may have enforceable property claims. The common usage carries no such freight. A researcher encountering "putative" in a legal context should resist treating it as a mere synonym for "alleged" or "supposed" and instead ask what legal regime the modifier triggers.

Recognized Forms
/SUBTYPES
Putative father: A man reputed to be the biological father of a nonmarital child. Distinguished from a legal father (established by adjudication, acknowledgment, or presumption). In modern American law, putative fathers who timely register with a state putative father registry may be entitled to notice of adoption proceedings and an opportunity to assert parental rights. Failure to register can result in termination of those rights without further notice.
Putative marriage: A formally invalid marriage treated as valid in equity for the benefit of a party who entered it in good faith and without knowledge of the impediment. The doctrine is civil law in origin and is recognized by statute or common law in a number of American jurisdictions. Rights that may be preserved include spousal support, inheritance, and community property claims, depending on jurisdiction.
Putative spouse: The good-faith party (or parties) to a putative marriage. The putative spouse doctrine protects the reasonable expectations of a party who believed in good faith that a valid marriage existed.
Putative owner / putative creditor: Less commonly encountered in modern American practice, but appearing in historical sources — particularly Scots law and civil law traditions — to describe persons holding a claimed property or creditor status not yet legally confirmed.

Why It Matters in Research
The term "putative" is a navigational signal, not just a modifier. When you encounter it in a historical source, identify which legal tradition is speaking: civil law jurisdictions (Louisiana, Quebec, and their historical predecessors) developed the putative marriage doctrine extensively; common law jurisdictions adopted it unevenly and often later. A case or treatise from a common law jurisdiction using "putative marriage" before the twentieth century may be borrowing civil law vocabulary without necessarily applying civil law doctrine — verify the jurisdictional context before assuming doctrinal alignment.
In family law research, the most consequential modern development is the proliferation of state putative father registries beginning in the 1970s and accelerating after the Supreme Court's decisions on the constitutional rights of unwed fathers. These registries fundamentally changed what "putative father" means procedurally: the status now triggers affirmative registration obligations, and researchers working with pre-registry case law should be careful not to read modern procedural requirements backward into older materials. Historical cases discussing putative fathers addressed a different procedural landscape.
The putative spouse doctrine presents a different research trap. Because it is equitable in origin and varies significantly by jurisdiction, historical dictionary sources tend to state it at a high level of generality that obscures whether and how a particular jurisdiction actually adopted it. Do not rely on Bouvier or Black's to confirm that a specific state recognized the doctrine at a specific time — go to the jurisdiction's statutes and cases directly.
The Burrill and Black's entries anchor "putative" primarily in Scots law references (Kames' Equity), which reflects the civil law ancestry of the concept. This is accurate as far as it goes but understates the doctrine's subsequent American development, especially in community property states.

Historical Dictionary Support
The historical dictionaries converge cleanly on the core meaning: reputed, supposed, commonly esteemed. Burrill traces the Latin root (putativus, from putare, to suppose) and offers the classical phrase pater puteri putativus — the reputed father of the child — with a citation to J. Brompton and Cowell, grounding the term firmly in medieval learned law.
Black's (both editions) and Burrill share the Kames' Equity citations for the Scots law application to creditors and proprietors. This narrow jurisdictional note reflects the civil law foundation of the concept in British legal history.
Bouvier makes the doctrinal point most directly: putative means "reputed to be that which is not" — a useful formulation because it captures the defining feature of the concept: legal fiction in service of fairness. Bouvier's reference to Toullier (a French civil law authority) and Lord Kames reinforces the civil law lineage.
Anderson's entry is the thinnest, essentially a cross-reference list. It confirms usage (putative father, wife, marriage) without adding analysis.
What the historical dictionaries collectively miss is the modern statutory architecture surrounding putative fathers — registries, notice requirements, and constitutional dimensions — and the jurisdictional patchwork of putative spouse recognition in American states. For those purposes, the historical shelf is a starting point only.

Jurisdictional Note
The putative marriage doctrine is most fully developed in civil law states (particularly Louisiana) and community property states, several of which codified it by statute. Common law states vary: some recognize the doctrine judicially, some by statute, and some have not clearly adopted it at all. The putative father registry system is a creature of state statute, and registry requirements, deadlines, and consequences differ materially across jurisdictions — a detail that significantly affects adoption and termination-of-parental-rights research.
