Definition
To alter is to change a thing in one or more of its elements, ingredients, or details without substituting an entirely new thing or destroying the subject's identity. The thing altered must still exist after the change — it has shifted in form or character, but continues to have legal existence. The term operates across several legal contexts: 1. INSTRUMENTS AND DOCUMENTS. To alter a written instrument is to change its operative terms — its parties, dates, amounts, or conditions — after execution. Alteration is distinct from forgery (which involves fabrication) and from mere correction before execution. A material alteration changes the legal effect of the instrument; an immaterial one does not. 2. PROPERTY AND GOODS. To alter physical property is to modify it in a way that changes its form, use, or identifying characteristics without wholly destroying or replacing it. Removal of a brand or serial number is a classic example. The altered object retains identity even as its nature shifts. 3. ALTER EGO (CORPORATE LAW). The phrase alter ego — from the Latin meaning "another self" — is a distinct legal term of art. In corporate law, it describes the doctrine by which courts disregard the separate legal existence of a corporation and hold its owners personally liable when the corporation is shown to be a mere extension of those individuals. This usage derives entirely from the Latin root and is treated separately below under RECOGNIZED FORMS/SUBTYPES. ---
Common Language
Modern common usage (Wiktionary): To change the form or structure of something; to become different; to tailor clothing to fit; to castrate or neuter an animal; to affect mentally. Historical common usage (Webster's 1913): "To make otherwise; to change in some respect, either partially or wholly; to vary; to modify." The 1913 definition also notes an obsolete sense meaning to agitate or affect mentally. The everyday word "alter" maps closely onto its legal meaning, but the law draws a critical line the common usage does not: alteration must preserve the identity of the thing affected. In ordinary speech one might say a building was "altered" by demolition and reconstruction — in legal usage, that would more likely constitute replacement, not alteration. The legal concept excludes changes so complete that the original thing no longer exists in any meaningful sense. ---
Common Confusion
ALTER vs. CHANGE vs. AMEND. These three terms are frequently used interchangeably in non-legal writing but carry distinct legal weight. To change may import the substitution of something entirely different. To amend carries a corrective or improving connotation — often used in legislative, constitutional, and pleading contexts — and typically implies formal process. To alter occupies the middle ground: a modification of existing substance that preserves the thing's identity. Researchers working with constitutional documents, statutes, or contracts should attend to which word the drafters chose; courts have treated the distinction as operative. ALTER EGO (doctrine) vs. PIERCING THE CORPORATE VEIL. These terms are sometimes used as synonyms, but alter ego is more precisely the theory of liability — the finding that a corporation is merely the alter ego of its owner — while piercing the corporate veil describes the judicial remedy that follows from that finding. Some jurisdictions recognize both as interchangeable; others treat them as analytically distinct steps. ---
Recognized Forms
/SUBTYPES MATERIAL ALTERATION. A change to an executed instrument that modifies the legal rights or obligations of any party. Under negotiable instruments law (UCC Article 3), a material alteration may discharge a party's liability or limit recovery to the instrument's original terms. IMMATERIAL ALTERATION. A change that does not affect the legal operation of the instrument. Generally without legal consequence. ALTER EGO. The Latin phrase meaning "another self." In corporate and entity law, the alter ego doctrine holds that when a shareholder or controlling party treats a legal entity as an extension of themselves — commingling funds, ignoring formalities, using the entity to perpetrate fraud — courts may disregard the entity's separate existence. The doctrine is the theoretical foundation for piercing the corporate veil. ALTERATION AS A PRODUCTS LIABILITY DEFENSE. In tort law, post-sale alteration of a product by a party other than the manufacturer may defeat or reduce a product liability claim. The question turns on whether the alteration was foreseeable and whether it was the proximate cause of the harm. ---
Why It Matters in Research
Researchers will encounter "alter" in at least three largely separate doctrinal streams — negotiable instruments, corporate veil-piercing, and tort products liability — that use the word in related but distinct ways. Conflating sources across these streams produces analytical errors. In historical sources, the boundary between "alteration" and "forgery" is especially significant and not always cleanly drawn. Older treatises sometimes categorize an unauthorized post-execution change to a document as a species of forgery rather than a distinct wrong. Researchers working with pre-UCC commercial law materials should verify which framework a source is applying. The materiality distinction in instrument alteration is a research trap: a change that appears minor on its face (a date, a place of payment) may be material as a legal matter if it alters a party's obligation. Conversely, a seemingly significant change to surplusage may be immaterial. Do not assess materiality from common sense alone; consult the governing instrument law. For the alter ego doctrine, jurisdictional variation is substantial. The factors courts weigh — commingling, failure to observe formalities, undercapitalization, fraud — differ in number, weight, and label across states. Sources from one jurisdiction should not be imported to another without verification. The Latin alter (meaning "another" or "the other of two") appears throughout Latin legal maxims and in Burrill's dictionary. Researchers using Latin-language sources or early common law materials will encounter it as a standalone term meaning "the other party" or "another person," distinct from its role in the compound phrase alter ego. ---
Historical Dictionary Support
The historical dictionaries converge on the core meaning but approach it from different angles. Black's (both editions) emphasizes the definitional line between alteration and substitution: altering operates on a subject matter that survives the change. Anderson's reinforces this with the observation that a thing which has ceased to exist cannot properly be said to have been altered — if it remains, it has merely changed form or nature. This is a philosophically precise and legally useful distinction that modern sources sometimes elide. Burrill's entry for "alter" is the outlier: it records only the Latin meaning — "another; a different person or party; a third person; an opposite party" — reflecting Burrill's orientation toward civil law and Latin-language sources. This entry is not a definition of the English verb as used in common law practice and should not be read as one. Researchers using Burrill for common law alteration doctrine will find nothing of direct use under this headword; the relevant material appears under related entries. Anderson's notable contribution is the connection to forgery: the making element of forgery can be satisfied either by original fabrication or by changing an existing document into something legally different — placing alteration at the boundary of forgery doctrine. This analytical linkage is less explicit in Black's and is worth flagging for researchers working on fraud and instrument crimes. None of the historical dictionaries address the alter ego doctrine under this headword, which reflects the doctrine's primarily twentieth-century development in American corporate law. Researchers seeking historical support for alter ego analysis will need to work from equity sources and early veil-piercing cases rather than from these dictionary entries. ---
Jurisdictional Note
Alteration of negotiable instruments is governed in most U.S. jurisdictions by UCC Article 3, providing substantial uniformity, though pre-UCC decisions remain relevant for historical research and some states retain idiosyncratic interpretations. The alter ego doctrine, by contrast, is governed by state common law with no uniform code equivalent; the operative factors and burden of proof vary meaningfully across jurisdictions. ---

Black's Law Dictionary • 1891
To make a change in; to mod- ify; to vary in some degree; to change some of the elements or ingredients or details, without substituting an entirely new thing or destroying the identity of the thing af- fected. This term is to be distinguished from its synonyms "change" and "amend." To change may import the substitution of an entirely different thing, while to alter is to operate upon a subject-matter which con- tinues objectively the same while modified in some particular. If a check is raised, in re- spect to its amount, it is altered; if a new check is put in its place, it is changed. To "amend" implies that the modification made in the subject improves it, which is not nec- essarily the case with an alteration. An amendment always involves an alteration, but an alteration does not always amend.

ALTERmain
Anderson's Dictionary of Law • 1890
To make a thing different from what it was; as, by cutting out a brandmark. 3 The word implies "another." A thing which ceased to exist can in no proper sense be said to be "altered." If altered it has merely changed its form or nature, but still has an existence. Thus, in forgery making may be by an original fabrication or by merely changing a thing already made into another thing. An altered note is still a note.4 To "alter judicial districts" means to change them. It is not a violation of usage to speak of the increasing or diminishing of a given number as an alteration or change in the number. Alteration. 1. A change or substitution of one thing for another: as, the alteration of a way.6 See ADDITION, 1. 2. An act done upon an instrument by which its meaning or language is changed. If what is written or erased has no tendency to produce this result or to mislead it is not an "alteration." The term applies to the act of the party entitled under the instrument and imports some fraud or improper design to change its effect. The act of a stranger is a mere "spoliation" or mutilation of the instrument, and does not change its legal operation as long as the original writing remains legible, and, if it be a deed, any trace of the seal remains.7 Material alteration. Such alteration as changes the language or meaning of the contract in a material particular. Immaterial alteration. Such merely verbal change as does not vary the contract in an essential particular.8 Suspicious alteration. Such change, apparent upon inspection, as would lead a man of ordinary caution to infer that the instru1 Evans v. Knorr, 4 Rawle, 68-70 (1833), cases; 22 111. 366. 2 L.

That is a "material alteration" which causes the instrument to speak a language different in legal effect from what it originally spoke; 1 or which gives the instrument a different legal effect.2 A material alteration made without consent after execution avoids the instrument; but not so as to words which the law would supply. The question of materiality is for the court. If attested as made before execution does not detract from credit; nor, if it is against the interest of the holder. If suspicious upon its face, the law presumes nothing, but leaves questions of time, person, and intent, to the decision of a jury. If immaterial, presumed to have been made before execution. But some authorities require explanation before any altered instrument can be admitted in evidence.3 It will not be presumed that a party would sign a document with material clauses interlined or in the margin. The rule is strict as to negotiables. The burden of explaining alterations in ancient writings is not imposed when they are taken from their proper repository. Formal blanks may always be filled. The material alteration of a written contract by a party to it discharges a party who does not authorize or consent to the alteration, because it destroys the identity of the contract and substitutes a different agreement. Any change which alters the contract, whether increasing or diminishing liability, is "material." 5 Some authorities hold that where there are no particular circumstances of suspicion the presumption of law is that the alteration was made contemporaneously with the execution, giving as a reason that a deed cannot be altered after its execution without fraud, which is never assumed without proof; other authorities hold the presumption to be the other way, and require an explanation of the alteration before the deed can be admitted in evidence. In the absence of proof the presumption is that a correction by erasure in a deed (a patent to land) was made before execution. This doctrine rests upon principle. "A deed cannot be altered after it is executed without fraud or wrong; and the presumption is against fraud or wrong." The cases are not uniform in this country, but the most stringent ones leave the question to the jury." 11 Greenl. Ev. § 565; 9 Baxt. 462. 2 Eckert v.
