Definition
Adjustment carries distinct legal meanings across several practice areas. The core sense in each is a formal settling or recalibration — of a loss, a debt, a status, or an account — through agreed or prescribed procedure.
1. Insurance (primary legal sense). The process of determining the amount an insured party is entitled to recover under a policy after a loss has occurred. Adjustment includes ascertaining the fact and extent of the loss, applying policy conditions and exclusions, making all allowances and deductions, and fixing the proportion each underwriter or insurer is liable to pay. The result is a settled figure binding on the parties when made with the intent to be final.
2. Tax law. A modification to income, deductions, basis, or tax liability required or permitted under the tax code. "Adjustments to income" — items subtracted from gross income to arrive at adjusted gross income (AGI) — are a foundational concept in federal income tax computation. Upward and downward adjustments to the basis of property affect gain or loss on disposition.
3. Immigration law. A change in an alien's immigration status while present in the United States, most commonly from a nonimmigrant or other temporary status to lawful permanent resident (LPR) status. This is the central meaning in "adjustment of status," the domestic alternative to obtaining an immigrant visa abroad at a consular post.
4. Commercial and general law. The settlement or reconciliation of conflicting monetary claims between parties, including the equitable distribution of shared obligations or benefits. Used in contexts such as average adjustment in maritime law, adjustment of accounts in partnership dissolution, and the allocation of prorated expenses at real estate closing.
Common Language
Modern common usage (Wiktionary): The action of adjusting something; a small change, minor correction, or modification; the settling or balancing of a financial account; the assessment by an insurance company of a claim and the settlement of that claim.
Historical common usage (Webster's 1913): The act of adjusting or the condition of being adjusted; bringing into proper relations; settlement of claims; an equitable arrangement of conflicting claims, as in set-off, contribution, exoneration, subrogation, and marshaling.
The common and legal meanings are close enough that the word rarely deceives a general reader — both treat adjustment as a process of bringing something into proper order. The research trap is not confusion but imprecision: in common usage, "adjustment" suggests a minor tweak, while the legal uses often describe a formal, binding determination. An insurance adjustment is not a small correction; it is a concluded legal settlement of a claim. An immigration adjustment of status is a permanent change in legal standing, not a procedural modification.
Recognized Forms
/SUBTYPES
Average Adjustment (Marine Insurance). The apportionment of a general average loss among the cargo owners, shipowner, and freight interests in proportion to the value of property saved. Performed by a specialized professional called an average adjuster.
Loss Adjustment (Property and Casualty Insurance). The broader insurance context — determination of the insurer's liability following any covered loss, whether or not marine in nature.
Adjustment of Status (Immigration). Formal administrative procedure under which an eligible alien present in the United States applies to U.S. Citizenship and Immigration Services (USCIS) to become a lawful permanent resident without departing the country for consular processing.
Basis Adjustment (Tax). An increase or decrease to the cost basis of an asset required by the tax code, affecting the calculation of gain or loss upon sale or other disposition.
Cost-of-Living Adjustment (COLA). Periodic modification of benefit amounts — Social Security payments, pension benefits, wage scales — tied to changes in a price index.
Why It Matters in Research
The single greatest research hazard with this term is domain confusion. "Adjustment" appears throughout the Law Mind corpus in insurance, tax, immigration, maritime, and commercial law contexts, often without a qualifying noun. A researcher pulling sources on "adjustment" without confining the search to a practice area will surface an undifferentiated mix.
Insurance sources dominate the historical legal dictionary record. All five source dictionaries define adjustment almost exclusively in the insurance (particularly marine insurance) context. Researchers using historical dictionaries to understand the tax or immigration sense of the term will find no guidance and should not assume the silence is meaningful — those specialized uses developed later or in separate statutory frameworks.
The immigration "adjustment of status" concept is entirely statutory in origin and will not appear in any of the historical dictionaries in this corpus. Researchers working in immigration law should proceed directly to the encyclopedia entries and relevant statutory materials rather than the historical dictionary shelf.
In tax research, "adjustment" is rarely used as a standalone term — the operative phrases are "adjustments to income," "basis adjustment," "tax benefit adjustments," and similar compound forms. Searching the corpus for "adjustment" alone in a tax context will produce noise.
For insurance research, the historical sources are genuinely useful. The process they describe — ascertaining loss, applying allowances and deductions, fixing each underwriter's proportionate share — reflects doctrine that remained stable across centuries of insurance law. Bouvier's note that adjustment must be "intended and understood by the parties to be absolute and final" to be binding captures a principle still operative in modern insurance disputes.
In real estate and commercial closings, "adjustments" (often shown on a settlement statement) refers to the proration of taxes, rents, insurance, and similar items between buyer and seller as of the closing date. This use is common in practice but underrepresented in the historical legal dictionaries.
Historical Dictionary Support
The five source dictionaries are in substantial agreement on the insurance meaning, differing only in detail and completeness. All center on marine insurance and share the core formulation: adjustment is the settling and ascertaining of the amount the assured is entitled to receive after allowances and deductions, with each underwriter's proportionate share fixed.
Rapalje & Lawrence is the most thorough on the marine insurance context, noting explicitly that the term applies to "the proportion which each underwriter is liable to pay" and cross-referencing merchant shipping law sources. Black's (both editions) follows closely the same formulation and cites Marshall's treatise on insurance.
Bouvier's adds the most practically useful point: no specific form is required for an adjustment to be valid, but it must be intended and understood by both parties to be final. This distinguishes adjustment from preliminary or interim loss estimates.
Burrill's entry is notable for a transcription artifact in the available text — the marine insurance definition is intercut with an unrelated entry on common of pasture — but the insurance substance it contains aligns with the other sources.
None of the five source dictionaries address the tax or immigration senses of the term. This is not a deficiency in the dictionaries but a reflection of historical timing: the federal income tax and the statutory immigration adjustment of status procedure both postdate the core editions of these works.
Jurisdictional Note
The insurance adjustment process is governed by a combination of policy terms, state insurance codes, and common law. State law controls the enforceability of adjustments and the obligations of adjusters, with variation in licensing requirements and unfair claims settlement practice standards. The immigration adjustment of status is exclusively federal, administered by USCIS under the Immigration and Nationality Act. Tax adjustments are governed by the Internal Revenue Code for federal purposes; states maintain parallel but often divergent adjustment rules for state income tax purposes.
