Definition
In legal usage, *fix* carries three related but distinct meanings, all built around the idea of rendering something certain, settled, or binding:
1. To liquidate or render a liability certain. A contingent or possible obligation becomes fixed when the conditions precedent are satisfied and the liability attaches as a present, definite legal obligation.
2. To determine or settle a legal right, rule, or amount. Legislatures and courts fix compensation, interest rates, boundaries, and other terms when they prescribe the controlling rule or amount by authoritative act.
3. To fasten liability upon a particular person. A party is "fixed" with liability when the facts and law combine to make that person legally responsible — transforming potential exposure into actual obligation.
In colloquial courtroom and transactional usage, "fixed" also appears as a shorthand for *fixed rate*, *fixed price*, or *fixed term*, meaning an amount or period that is set and not subject to variation. This usage is descriptive rather than a distinct legal term of art.

Common Language
Modern common usage (Wiktionary): To attach, affix, or hold in place; to repair something; to direct a piercing look at someone; to focus or settle on a concept.
Historical common usage (Webster's 1913): Fixed; solidified. [Obs.] (Chaucer)
The gap matters for researchers: in ordinary English, *fix* most commonly means to repair or to attach physically. In legal sources, it almost never carries either meaning. When a legal text says a party "fixed" something, it means they made it certain, binding, or ascertainable — not that they repaired it. A reader importing the common meaning will systematically misread legal instruments and opinions.

Common Confusion
*Fix* in legal sources should not be confused with its colloquial sense of manipulating an outcome corruptly (as in "fixing a game" or "fixing a jury"). That usage — meaning to arrange a fraudulent result through bribery or improper influence — appears in criminal law contexts as part of offenses like jury tampering or bribery, but it is analytically separate from the civil law sense of rendering a liability certain. Historical sources use both meanings without always flagging the distinction. A nineteenth-century opinion that describes a party as having "fixed" a proceeding requires careful contextual reading to determine which sense is operative.

Why It Matters in Research
The primary research trap with *fix* is its chameleon quality: it shifts meaning depending on whether the surrounding context is liability law, constitutional law, contract drafting, or criminal law. Historical sources, including Black's second edition, define the term almost exclusively in the liability-rendering sense, but corpus searches will surface the term in all four contexts simultaneously.
**Liability contexts.** When researching when a cause of action accrues, when a lien attaches, or when a party's obligation matures, the question is often precisely *when* liability became fixed. The transition from contingent to fixed is legally operative — it may determine the limitations period, priority among creditors, or whether a bankruptcy estate can avoid the obligation. Cases and treatises from the late nineteenth and early twentieth centuries use "fixed" and "liquidated" in close proximity, sometimes interchangeably. They are not synonyms: liquidated refers to an amount that is ascertained or agreed; fixed refers to the character of the obligation as no longer contingent. Conflating them can distort analysis of historical damages doctrines.
**Constitutional and statutory contexts.** Bouvier's entry captures a usage that Black's underemphasizes: legislative bodies *fix* compensation, rates, or standards. In constitutional law research, particularly involving legislative delegation of power or separation of powers challenges, the question of whether a legislature "fixed" a rule or delegated the fixing to an agency is substantively important. Corpus searches for "fix" in constitutional contexts will yield material on rate-setting, legislative compensation clauses, and price regulation that requires this reading.
**Fixture law.** Anderson's entry drifts into fixture law — personal property affixed to real property — which reflects a legitimate historical connection. The word "fixed" appears in early fixture analysis because the question was whether an item was so affixed as to become part of the realty. Researchers working on fixture or secured transaction problems in historical sources will encounter this usage and should recognize it as distinct from the liability-rendering sense.
**Rate and price contexts.** Modern corpus material uses "fixed" heavily in transactional and regulatory settings: fixed-rate mortgages, fixed-price contracts, fixed annuities. These are descriptive usages, not terms of art in the classical sense, but they have regulatory significance in insurance and securities law contexts.

Historical Dictionary Support
Black's (both editions) and Black's second edition are in close agreement: fix means to liquidate, to render certain, and to transform contingent liability into present liability. This is the core definition and the most useful for liability and accrual research.
Bouvier's adds the constitutional dimension — that a legislature "fixes" compensation by prescribing the controlling rule — which Black's does not capture adequately. Researchers using only Black's will miss this usage in early constitutional materials.
Anderson's entry is partially garbled in the surviving text but meaningfully connects *fix* to fixture doctrine, linking the concept of something being "fastened upon" realty to the broader sense of permanence and attachment. This is historically coherent but analytically distinct from the liability-rendering sense.
Burrill's entry, as available in the corpus, does not address *fix* directly in its surviving text and should not be relied upon for this term.
None of the historical dictionaries adequately address the criminal law sense of *fix* as corrupt manipulation, which is a significant omission for researchers working with twentieth-century materials. That usage requires recourse to criminal law treatises and case law rather than the standard reference dictionaries.

Jurisdictional Note
The liability-rendering sense of *fix* is used consistently across American jurisdictions without meaningful variation. The constitutional sense — legislatures fixing compensation or rates — has generated state-specific doctrine depending on particular constitutional text, and researchers should not assume that one state's interpretation of what it means to "fix" a rate or salary translates directly to another.
