Definition
TIONE is a fragmentary label appearing in historical legal dictionaries as a heading or catch-term, not a self-contained legal term. The dictionary entries gathered under this heading are artifacts of alphabetical indexing in early law dictionaries, where the string "tione" appears as the tail-end of Latin words or as a truncated cross-reference stub. The substantive legal content associated with this heading in the historical sources relates to three distinct topics:
1. A writ of apportionment (pro rata tenement). A common-law writ available to a joint tenant or tenant in common who was distrained for more rent than his proportionate share of the land warranted. The writ compelled the distraining party to charge each co-holder only according to their rateable proportion. Referenced in Reg. Orig. 182 and Fitzherbert's Natura Brevium 234.
2. De verborum significatione. A title in the Digest of Justinian (Dig. 50, 16), consisting entirely of definitions of Latin legal terms and phrases. This title was one of the most heavily consulted sections of the Pandects for civilian legal argument and remains a primary reference for Roman law terminology.
3. Surcharge after admeasurement of pasture. A writ that lay where admeasurement of common pasture had already been made, and the party who originally surcharged the common did so again in violation of that admeasurement. Referenced in Reg. Orig. 157 and Fitzherbert's Natura Brevium 126.
The entries from Bouvier associated with this heading are clearly misaligned cross-references — fragments of neighboring Latin headings (IN SIMPLICI PEREGRINATIONE, IN SOLIDUM) that were captured by the same alphabetical stub.

Common Confusion
The heading "TIONE" as it appears in historical dictionaries does not represent a legal concept in its own right. It is an artifact of how Latin-derived terms were alphabetized and abbreviated in early print dictionaries. Researchers who encounter this heading in index tables or digests of Black's or Bouvier's should not treat it as a term of art. The substantive legal rules described under this heading are better located under their full Latin headings: DE VERBORUM SIGNIFICATIONE, PRO RATA, ADMEASUREMENT OF PASTURE, and related writs.

Why It Matters in Research
Researchers working in the Law Mind corpus who encounter "TIONE" as a dictionary entry should treat it as a navigational hazard rather than a term to be defined. Several practical points:
First, early law dictionaries — Black's in particular — used abbreviated or truncated Latin strings as alphabetical anchors, especially where a cluster of Latin terms shared a common suffix (-tione being the ablative/accusative singular of third-declension Latin nouns ending in -tio). Entries gathered under such a heading may span unrelated legal topics that share only a typographic accident.
Second, the writ pro rata (apportionment of rent among co-tenants) is the substantive rule most durably associated with this heading. That writ has genuine historical importance in the law of co-tenancy and distraint, and tracing its development requires moving to the fuller headings DISTRESS, JOINT TENANCY, and APPORTIONMENT in the same dictionaries.
Third, De verborum significatione (Dig. 50, 16) is a critical research resource for any work involving Roman-derived civil law concepts. It is not a writ or a rule of English common law but a definitional title of the Corpus Juris Civilis. Researchers in civilian or mixed-jurisdiction contexts should consult it directly rather than through this indirect index reference.
Fourth, the admeasurement of pasture writ is an archaic common-law remedy with no modern analog. It appears in early-modern form books (Fitzherbert, Registrum Brevium) and is of historical interest primarily for the study of common rights and agrarian tenure.

Historical Dictionary Support
The historical dictionaries are not in disagreement here because they are not, in fact, defining the same thing. Black's (both editions) presents the apportionment writ under this heading with consistent substance, citing Reg. Orig. 182 and Fitzherbert's Natura Brevium 234 — citations that check out against known form-book sources. Rapalje & Lawrence takes a different cut and leads with the surcharge-after-admeasurement writ, citing Reg. Orig. 157 and Fitzherbert 126, appending the maxim De similibus ad similia eadem ratione procedendum est as a gloss. Bouvier's entries under this heading are clearly fragments of neighboring entries and add no independent definitional content here.
What the historical dictionaries miss: none of them flags the meta-problem — that "TIONE" is a typographic artifact, not a term. A researcher relying solely on these sources could reasonably but wrongly conclude that a unified legal concept called "TIONE" exists.

Jurisdictional Note
The apportionment writ described under this heading was a creature of English common law and was not transplanted as a named writ into American practice. The underlying principle — that a co-tenant cannot be compelled to bear more than a proportionate share of a common obligation — survived in American property law, but through statutory apportionment frameworks and equitable contribution rather than through any writ by this name.
