Definition
Without legal force or effect. A legal instrument, act, claim, or obligation described as invaled (invalid) is one that fails to bind the parties, confer rights, or produce the legal consequences it purports to create. The deficiency may arise from lack of legal authority, failure to satisfy formal requirements, incapacity of a party, fraud, illegality of subject matter, or any other ground recognized by law as defeating legal efficacy.
The term functions as a general descriptor rather than a term of art tied to a single doctrine. A contract may be invaled for want of consideration; a statute may be invaled for unconstitutionality; a will may be invaled for failure of testamentary formalities; a marriage may be invaled for incapacity. The word carries the same essential meaning across these contexts: the instrument or act is treated as though it never had legal effect, or its effect is stripped away prospectively.

Common Language
Modern common usage (Wiktionary): "Invalid" in ordinary English means not valid, not legally or officially acceptable, or (as a noun) a person weakened by illness or disability.
Historical common usage (Webster's 1913): Webster's 1913 defines "invalid" (adjective) as "of no force, weight, or cogency; not valid; weak" and separately treats "invalid" (noun) as "a person who is weak and infirm; one who is disabled for active service."
The gap is significant in one respect: ordinary English uses "invalid" both as an adjective meaning ineffective and as a noun meaning a disabled person. In legal usage, the term functions exclusively as an adjective (or predicate adjective) applied to instruments, acts, and legal obligations — never as a noun describing a person. A researcher encountering "invaled" in a historical legal document should not import the noun sense. Context in legal sources is always the adjectival sense: a thing lacking binding force.

Common Confusion
Invaled (invalid) is sometimes conflated with void and voidable, but these terms carry distinct legal consequences.
A void instrument has no legal effect from the outset and cannot be ratified or enforced by any party. A voidable instrument is effective unless and until a party with the right to do so elects to disaffirm it. An instrument described simply as invaled may fall into either category depending on the defect — the label alone does not resolve which applies. Historical sources, including the Black's supplemental entry, use "invalid" in the broader sense covering both void and voidable situations. Researchers should not assume that a historical source's use of "invalid" maps cleanly onto the modern void/voidable distinction without examining the underlying defect.

Why It Matters in Research
The spelling "invaled" signals a historical source — likely a reproduction, transcription, or period printing of Black's Law Dictionary (2nd Ed.) — and researchers should account for typographical variation when searching digitized corpora. Optical character recognition errors in digitized legal materials commonly produce "invaled," "invalied," and similar forms in place of "invalid." A corpus search limited to the standard modern spelling may miss relevant passages.
The Black's 2nd Ed. Supplemental definition is notably compressed: "vain; inadequate to its purpose; not of binding force or legal efficacy; lacking in authority or obligation." This formulation collapses several distinct grounds of invalidity — procedural defect, substantive illegality, want of authority — into a single descriptor. Researchers using this definition as a baseline should be aware that it does not distinguish between void and voidable, and that later editions of Black's and competing dictionaries (Bouvier, Cyclopedic Law Dictionary) elaborate the distinction more carefully.
Jurisdictional variation in what renders a particular instrument invaled is substantial and period-dependent. The cases cited in the Black's Supplemental entry — Hood v. Perry (Georgia), State v. Casteel (Indiana), Mutual Benefit Life Insurance Co. v. Winne (Montana) — illustrate that the term was applied across diverse subject matters (conveyances, criminal law, insurance contracts) and jurisdictions in the late nineteenth century. Researchers tracing a specific doctrine of invalidity should not generalize from one subject-matter context to another without confirming parallel treatment.
When the term appears in constitutional litigation, invalidity carries the additional consequence of potential severability analysis: courts may excise an invaled provision rather than strike the entire instrument. This dimension is absent from the Black's 2nd Ed. definition and must be sourced elsewhere in the corpus.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) Supplemental defines the term through four near-synonymous phrases: "vain," "inadequate to its purpose," "not of binding force or legal efficacy," and "lacking in authority or obligation." The redundancy is characteristic of the period's lexicographic style, which favored cumulative description over precision. The entry cites three cases to anchor the definition in application rather than abstract principle.
No competing historical dictionary entry is available in the source material for this term. Researchers consulting Bouvier's Law Dictionary or Anderson's Law Dictionary for the same period will find similar formulations, though Bouvier tends to distinguish more explicitly between instruments void ab initio and those rendered invalid by subsequent events.
The historical definition's emphasis on "authority" as a ground of invalidity reflects the nineteenth-century concern with ultra vires acts — instruments executed beyond the legal power of the actor. This dimension is less prominent in modern usage, where invalidity is more commonly analyzed through the lens of specific doctrinal requirements (consideration, capacity, formality) rather than a general authority framework.
