Definition
DETERMINATION carries two distinct legal meanings that appear throughout the sources and across legal contexts:
(1) Decision by a tribunal. A determination is the resolution of a question, dispute, or controversy by a court, agency, or other authoritative body. In this sense, it refers to the outcome of adjudicative proceedings — the formal conclusion reached after considering evidence and applying law. It is used both specifically (a court's finding on a discrete issue) and broadly (the overall disposition of a case or proceeding).
(2) Ending or termination of a legal interest. In property law and related contexts, a determination is the coming to an end of an estate, right, power, or authority — not by natural expiration according to a fixed schedule, but contingently, by operation of law or the occurrence of some event. This usage is especially common in describing estates at will and life estates, where the termination depends on circumstances rather than a set date.
Common Language
Modern common usage (Wiktionary): The act of determining, or the state of being determined; also used for the result of a measurement or inquiry, and in ordinary speech for a quality of mind — resoluteness or decisiveness.
Historical common usage (Webster's 1913): The act of determining or the state of being determined; bringing something to an end or limit; direction toward a certain end; also, the quality of reaching definite conclusions — decision of character.
In ordinary English, determination is most familiar today as a personal virtue — firmness of purpose, perseverance. In legal usage, this meaning is entirely absent. The legal term is always procedural (a tribunal's decision) or doctrinal (the ending of a property interest). A researcher encountering the word in a legal instrument or opinion should not import the lay sense of resolve or intent.
Common Confusion
The two legal meanings of determination are frequently read past each other in historical sources. A treatise discussing the "determination of a lease" is using the property-law sense — the lease has ended. A court "making a determination" is using the adjudicative sense. The confusion is compounded because older texts sometimes use determine and determination interchangeably with decide, adjudge, and expire, without flagging which sense controls. Burrill draws a specific distinction between determination and expiration: expiration implies a fixed endpoint already built into the instrument, while determination implies a contingent ending triggered by some event or condition. This distinction matters in property disputes where the nature of an estate's ending affects the rights of remaindermen and third parties.
Recognized Forms
/SUBTYPES
Determination of a lease or estate: The contingent ending of a leasehold or other property interest by act of the parties, breach of condition, or operation of law — as distinguished from expiration by lapse of a fixed term.
Determination of an authority: The termination of an agent's or official's power to act, typically upon completion of the task for which authority was granted or upon occurrence of a specified condition.
Determination of will: A term of art for the ending of an estate at will, which by definition cannot expire on a fixed date and so is always a determination in Burrill's sense — contingent and dependent on the act or will of a party.
Judicial determination: A court's or tribunal's formal decision on a question of law or fact, used in contrast to informal or advisory opinions.
Why It Matters in Research
The dual meaning of determination is a genuine research trap in historical sources. Pre-twentieth-century legal writing shifts between the adjudicative and property-law senses without signaling the switch, and modern researchers trained in the adjudicative usage may misread passages dealing with estates. Conversely, property scholars may overlook the adjudicative usage in older case law.
In administrative law research, determination has expanded significantly beyond either historical sense. Modern regulatory materials use determination to describe agency findings, rule interpretations, and eligibility decisions — a usage that is functionally adjudicative but procedurally distinct from court judgments. Historical dictionaries do not anticipate this administrative meaning, so researchers working in regulatory contexts should treat the historical entries as partial coverage only.
Jurisdictional variation is also relevant in the property-law sense. In jurisdictions that modernized their real property vocabulary through statutory reform, determination of estates may have been replaced with termination or expiration in the statutory text, even when the underlying concept tracks the contingent/fixed distinction Burrill identifies. Researchers should check whether the jurisdiction's current code preserves or collapses this distinction.
In criminal law research, determination surfaces in specific doctrinal contexts — custody determination for Miranda purposes, bail determinations, and competency determinations — each of which has acquired its own body of procedural rules. These specialized uses are largely post-historical-dictionary and require current doctrinal sources.
Historical Dictionary Support
The sources agree on both core meanings, with useful variation in emphasis. Black's (both editions) states each meaning cleanly and without elaboration. Bouvier adds specific property-law texture, citing Comyn's Digest on estates by grant and Blackstone on determination of will, and notes that determination of an authority ends when the return-day of a writ passes — a detail that connects the property sense to procedural contexts. Rapalje & Lawrence present the two meanings in numbered parallel form, the most structurally explicit treatment, and flag that determine in a statute does not necessarily mean adjudge — a caution for statutory interpretation that the other sources miss.
Burrill offers the most analytically useful treatment of the property-law sense. His distinction between determination (contingent ending) and expiration (fixed ending) is drawn from Blackstone and Crabb's Real Property, and it is a distinction the other dictionaries either elide or omit. This makes Burrill the preferred source for property-law research involving the term.
All five sources predate the administrative law expansion of determination and are silent on agency proceedings. Researchers should treat the historical entries as covering the common-law core only.
Jurisdictional Note
In English and early American property law, determination of an estate carried precise technical force distinguishing contingent endings from fixed ones. American jurisdictions that codified property law in the nineteenth and twentieth centuries often replaced determination with termination in statutory text, which may or may not preserve the contingency distinction. In modern administrative law, determination is a term of art defined by statute or regulation in specific regulatory schemes, and its meaning may vary by agency context.
