Definition
To adjust, in legal usage, means to determine what is owed, settle a disputed or unliquidated claim, or bring competing rights or accounts into proper relation. The term appears across several distinct legal contexts:
1. Insurance. To investigate a loss, determine the amount payable under a policy, and settle the claim accordingly. This is the most technically developed legal use of the term and has generated its own body of practitioners (adjusters) and doctrine (adjustment).
2. Accounts and debts. To liquidate or reconcile competing claims or cross-demands — determining what, if anything, one party owes another after offsets, credits, and counterclaims are applied.
3. Administrative and regulatory law. To modify a status, rate, amount, or entitlement in accordance with a legal standard or formula. Tax law uses "adjust" in this sense extensively (adjusted basis, adjusted gross income). Immigration law uses "adjust status" as a term of art for changing a noncitizen's immigration classification to lawful permanent resident without leaving the United States.
4. General settlement. Broadly, to bring any disputed matter to a satisfactory resolution agreed upon by the parties.

Common Language
Modern common usage (Wiktionary): To modify; to improve or rectify; to change to fit circumstances; to settle an insurance claim.
Historical common usage (Webster's 1913): To make exact; to fit; to make correspondent or conformable; to bring into proper relations. To put in order; to regulate, or reduce to system. To settle or bring to a satisfactory state so that parties are agreed in the result.
The common and legal meanings share the same root sense — bringing something into proper alignment — but legal usage adds a precise procedural dimension. In law, to adjust is not merely to modify informally but to undertake a formal determination of rights or amounts, often with binding effect. The insurance and immigration law uses are especially technical: an insurance adjuster performs a quasi-judicial function, and "adjusting status" in immigration law has no ordinary-English analogue at all.

Common Confusion
ADJUST vs. SETTLE: These terms appear in tandem in older legal sources (Bouvier pairs them explicitly) and are sometimes treated as synonyms. They are not. To settle typically implies agreement between parties and the extinguishment of a claim. To adjust may precede settlement — it is the act of determining what is owed — and can occur unilaterally, as when an insurer adjusts a claim. An adjusted claim has been evaluated and quantified; a settled claim has been resolved and closed.
ADJUST STATUS (immigration) vs. ADJUST (general): Researchers working across practice areas should be alert to the immigration-specific compound. "Adjust status" is a statutory term of art under the Immigration and Nationality Act with its own eligibility rules, procedures, and history. It does not mean merely to change or modify a person's immigration paperwork — it refers to a specific administrative process with permanent legal consequences. Conflating this with the general sense of "adjust" produces serious research errors.

Why It Matters in Research
The word "adjust" is a research trap precisely because it is so ordinary-looking. Corpus researchers will encounter it in at least four distinct legal registers — insurance, accounting, tax, and immigration — and the operative meaning shifts substantially across each.
In historical sources, "adjust" appears most often in insurance and mercantile contexts. Nineteenth-century cases and treatises using "adjust" almost certainly mean insurance loss adjustment or account reconciliation. Do not import the modern administrative-law sense (regulatory modification, tax basis adjustment) back into pre-twentieth-century materials.
The insurance adjustment meaning is the most doctrinally developed in the historical dictionaries. Anderson's entry is the most complete of the historical shelf sources: it defines not only the verb but "adjuster" and "adjustment" as standalone terms, and flags the useful compound "unadjusted" as it appears applied to claims. Researchers tracking insurance disputes in historical sources should note that an "unadjusted" claim is one where liability and amount have not yet been determined — it is not merely unpaid.
In tax research, "adjusted" functions as a modifier with technical meaning fixed by statute and regulation. "Adjusted gross income," "adjusted basis," and similar compounds are not synonyms for "reduced" or "modified" in any colloquial sense. The Law Mind Tax Encyclopedia entry on adjusted gross income is the appropriate starting point for that line of research.
In immigration research, "adjustment of status" is a creature of the post-1952 statutory framework. Historical immigration sources will not use the phrase in its modern sense. Researchers should consult the relevant Immigration Law Encyclopedia entries for the country-specific adjustment programs (Cuban Adjustment Act, Nicaraguan Adjustment) that operate under distinct eligibility rules outside the general adjustment framework.

Historical Dictionary Support
The four shelf sources are in substantial agreement on the core meaning: to determine what is due and to settle it. Black's (both editions) leads with the relational sense — "to bring to proper relations" — while Bouvier draws a useful distinction between liquidated and unliquidated claims. For a liquidated claim (amount already certain), to adjust means to pay. For an unliquidated claim (amount disputed or uncertain), to adjust means first to determine what is due. This distinction, which Black's elides, is practically significant in historical research involving contested accounts.
Anderson's is the most expansive of the historical entries and the only one to develop "adjuster" and "adjustment" as derivative terms. Its definition of "adjustment" as "settlement of the relative rights of parties, of a demand or cross-demands of any nature" is broader than the insurance-specific sense and worth noting for researchers encountering the term in non-insurance contexts.
Black's 2nd edition adds case citations absent from the 1st edition, which grounds the definition in reported authority and confirms the insurance-adjustment context predominated in turn-of-the-century case law.
None of the historical dictionaries address the immigration or tax-law senses of "adjust," which are twentieth-century statutory developments beyond their scope.

Jurisdictional Note
Insurance adjustment practices are regulated at the state level, and the licensing and duties of public adjusters vary across jurisdictions. The tax and immigration uses of "adjust" are governed by federal law and are uniform nationally, though state tax codes may use the term with independent definitions.
