Definition
"Ter" is not a standalone legal term with a unified definition. It appears in legal sources exclusively as a Latin prefix or abbreviation embedded within compound legal terms and phrases. In that capacity, it carries the Latin meaning of "three times" or "thrice," used to distinguish a third instrument, proceeding, pleading, or document in a series — parallel to the use of "bis" (twice) or "quater" (four times) in the same convention.
As a discrete dictionary entry, "ter" surfaces in legal indexes and digests as a fragment — a shorthand notation or abridged heading pointing toward fuller entries. The source material attributed to this entry in historical law dictionaries reflects content misassigned under the heading rather than definitions of "ter" itself: the entries variously describe the unintentional killing of a person in the course of an unlawful but non-felonious act (se defendendo or misadventure territory), qualified property in animals ferae naturae, the plea of plene administravit praeter, Lancaster palatine court jurisdiction, and digest notations relating to uttering. None of these belong to "ter" as a term; they appear to be artifacts of alphabetical proximity or indexing error in the historical sources.
Common Confusion
"Ter" should not be confused with the entries that have migrated into its dictionary position. Researchers seeking the executor's plea should look under PLENE ADMINISTRAVIT PRAETER. Those seeking the qualified property doctrine in wild animals should look under FERAE NATURAE or QUALIFIED PROPERTY. Those seeking Lancaster court jurisdiction should look under DUCHY COURT or COURT OF THE DUCHY CHAMBER OF LANCASTER.
Why It Matters in Research
Researchers encountering "ter" in a Law Mind corpus search should proceed with caution. The term almost never appears as a freestanding legal concept. Its most common legitimate appearance is as a suffix notation in citation practice — for example, distinguishing a third reported case between the same parties (Jones v. Smith ter) — or as a component of Latin maxims and brocard phrases where the count of repetitions carries substantive significance.
The historical dictionary entries catalogued under this heading illustrate a structural hazard in using nineteenth-century legal dictionaries: alphabetical proximity and abbreviated indexing can cause entries from neighboring headings to bleed into adjacent ones, particularly in scanned or transcribed digital corpora. What appears under "ter" in these sources is more accurately attributable to entries for terms beginning with "ter-" (such as TERCE, TERMES, TERM, TERRA) or to nearby unrelated entries. A researcher relying on this heading as a substantive definition would be misled.
If you are searching for a legal concept and have arrived at "ter," the intended term is almost certainly one of the following: TERM (a fixed period of time; a session of court), TERCE (a widow's right of a third in Scots law), TERRE TENANT (one in actual possession of land), or a Latin phrase in which "ter" signals a third iteration.
Historical Dictionary Support
The historical dictionaries — Black's (1st and 2nd editions), Bouvier's, Burrill's, and Rapalje & Lawrence — do not offer a coherent independent definition of "ter" as a legal term. The entries appearing under this heading in the source material are substantively unrelated to each other and to the headword. Black's (1st Ed.) entries concern the killing of a person during an unlawful non-felonious act, qualified property in wild animals, and the executor's plea of plene administravit praeter. Bouvier's and Rapalje & Lawrence entries address the Lancaster palatine equity court and digest citations for uttering offenses.
This pattern suggests one of two explanations: either "ter" functioned purely as an index fragment pointing to fuller entries elsewhere in those volumes, or the entries were misfiled in the process of compilation or digitization. Burrill's Law Dictionary, which is especially attentive to Latin terms and their operational meanings in pleading and practice, would be the most likely source for a substantive treatment of "ter" as a prefix — but no such entry surfaces in the provided material. Historical sources are silent on "ter" as a term of art in its own right, and no treatise or reported authority appears to have treated it as such.
