Definition
Unmarried describes a person who does not have a legally recognized spouse. The term carries two distinct meanings depending on context:
1. Never having been married. The primary and historically dominant meaning: a person who has never entered into a valid marriage. Used in this sense, "unmarried" excludes those who were once married but are now widowed or divorced.
2. Not currently having a husband or wife. A broader, contextual reading: a person without a living spouse at the time in question, regardless of marital history. Under this construction, a widow, widower, or divorced person may qualify as "unmarried" for the purpose of a particular instrument, statute, or legal relationship.
Which meaning controls depends entirely on the governing document, statute, or jurisdiction. Courts look to context — the purpose of the provision, surrounding language, and the drafter's apparent intent — to determine which sense applies.
Common Language
Modern common usage (Wiktionary): Having no husband or wife.
Historical common usage (Webster's 1913): Not married; single; also, of or relating to the unmarried state; as, an unmarried person.
Both the common and legal meanings track closely, but the legal term introduces a critical ambiguity that ordinary usage does not. In everyday speech, "unmarried" simply means not currently married, with no particular attention to whether the person was ever married before. In legal instruments — wills, trusts, benefit designations, intestacy statutes — the distinction between "never married" and "not currently married" can be outcome-determinative. A drafter who means one thing may write language that courts interpret as the other.
Common Confusion
The two senses of "unmarried" are frequently confused in drafted instruments and sometimes in statutes. A bequest to "my unmarried children" may be intended to exclude only those currently in a marriage, or it may be intended to exclude any child who has ever been married. Courts have reached different results on nearly identical language. Researchers encountering the term in historical documents, wills, or statutes should not assume a uniform meaning and should examine the jurisdiction's interpretive case law before drawing conclusions.
"Unmarried" should also be distinguished from SINGLE, which in tax and administrative law often has a specific technical definition that may or may not align with marital status as understood in family law.
Why It Matters in Research
The dual meaning is the central research trap. When working with wills, trust instruments, or older statutes, do not assume which sense of "unmarried" the drafter intended. The same word in the same era could be interpreted either way depending on the court.
Historical documents pose a particular challenge. Before divorce was common and legally accessible, the distinction between "never married" and "not currently married" mattered less in practice — most unmarried adults in older instruments were genuinely never-married. As divorce became more prevalent in the 20th century, the interpretive tension sharpened, and courts began addressing the ambiguity more explicitly.
The term also surfaces in a modern context that the historical dictionaries could not anticipate: cohabitation, domestic partnerships, and unmarried parentage. Statutes and judicial decisions addressing property rights, support obligations, and parental rights frequently use "unmarried" as a qualifying term, and the meaning in those contexts is almost always the broader one — not currently married — rather than "never having been married." Researchers working in family law should consult the encyclopedia entries on unmarried cohabitants for how modern doctrine treats persons who are unmarried in the current-status sense.
Jurisdictional variation in intestacy and probate statutes is significant. Some states have updated statutory definitions to clarify which sense controls; others have not, leaving the question to case-by-case interpretation.
Historical Dictionary Support
Bouvier's is the more useful source here. It expressly acknowledges the dual meaning — primary sense as "never having been married," secondary sense as "not having a husband or wife at the time in question" — and signals that courts have applied both readings to the same term. The House of Lords cases Bouvier cites (9 H.L. Cas. 601) appear to have generated the interpretive framework that shaped subsequent common law treatment of the term. Researchers working with 19th-century English-origin doctrine will find Bouvier's formulation directly applicable to American courts that borrowed from English equity practice.
Anderson's adds nothing beyond cross-references to MAN and MARRIAGE, offering no independent analysis. Its entry reflects the 19th-century assumption that "unmarried" was self-evident enough to need only a pointer to related terms — an assumption that the case law contradicts.
Neither historical dictionary addresses the modern cohabitation context, domestic partnership law, or the administrative and tax law uses of the term. These are 20th- and 21st-century developments that require consulting current sources.
Jurisdictional Note
Statutes governing intestate succession, insurance beneficiary designations, and public benefits vary in whether they define "unmarried" expressly and, when they do, which sense they adopt. Some jurisdictions have enacted explicit statutory definitions that resolve the ambiguity; researchers should not assume the common law dual-meaning framework applies where a controlling statute speaks directly to the term.
