Definition
"Tation of suit" is an archaic procedural term referring to the formal commencement or bringing of a legal action — that is, the act of initiating litigation by a party. The phrase captures the moment at which a suit is put in motion before a court, triggering the court's jurisdiction over the matter and the parties' obligations to appear and respond.
The term is closely associated with the Latin maxim recorded in Rapalje & Lawrence: *Contestatio litis eget terminos contradictarios* — "the joinder of issue in a suit needs contradictory terms" (Jenk. Cent. 117). This connection situates "tation of suit" within the pleading framework of early common law, where the formal "contestation" of a suit (the *contestatio litis*) was the procedural moment at which the parties joined issue, each asserting contradictory positions. The full phrase "contestation of suit" — of which "tation of suit" is a fragment — referred to this issue-joining stage as the foundational act that gave the litigation its adversarial shape.
In modern practice, the concept maps roughly onto the filing of a complaint and the defendant's responsive pleading, together constituting the moment when a genuine dispute is formally before the court.

Common Confusion
"Tation of suit" as it appears in older sources is almost certainly a truncated rendering of "contestation of suit" — a term derived from the civil and canon law concept of *contestatio litis*. Researchers encountering "tation of suit" in isolation should treat it as a fragment, not a freestanding term of art. The full phrase "contestation of suit" carries the substantive meaning; the truncated form likely reflects a copying or indexing artifact in historical legal materials. Do not confuse "contestation of suit" with the broader modern concept of "commencement of suit," which focuses on filing mechanics rather than issue-joining.

Why It Matters in Research
This term is primarily a trap for historical researchers rather than a living concept. Key navigational notes:
**It is almost certainly a fragment.** Any historical source rendering "tation of suit" as a standalone entry is almost certainly reproducing a partial phrase. The operative term is "contestation of suit" (*contestatio litis*), which has a well-developed history in civil law, canon law, and early English equity practice. Researchers should search for the full phrase.
**Civil law and equity origins matter.** The *contestatio litis* was a formal procedural act in Roman civil procedure marking the point at which the parties submitted their dispute to the judge. It migrated into canon law and from there influenced English equity pleading. In common law courts, the concept was less formalized, but the principle — that a suit requires contradictory positions joined between the parties — was absorbed into pleading doctrine.
**The Jenkins citation is real but narrow.** Rapalje & Lawrence cites Jenk. Cent. 117, referring to *Eight Centuries of Reports* by David Jenkins (published posthumously, 1661), a collection of cases from the Exchequer and other courts. Researchers using this citation should be aware that Jenkins's reports are of limited authority and were controversial even in their own era. The maxim is useful as evidence of how early modern lawyers understood pleading structure, not as binding precedent.
**Corpus connections.** In the Law Mind corpus, suits against states, citizen suits in administrative enforcement, and development agreements involving suit-triggering conditions each touch on the question of when a "suit" formally begins and what procedural acts constitute its initiation. The *contestatio litis* concept is relevant background for understanding why issue-joining — not merely filing — was historically treated as the constitutive act of litigation.

Historical Dictionary Support
Rapalje & Lawrence is the sole dictionary source for this entry, and their treatment is thin — one maxim, one citation. The entry appears to be a fragment of a larger discussion of *contestatio litis* rather than a complete definition of a freestanding term.
What Rapalje & Lawrence do capture, correctly, is the core principle: a suit in the adversarial tradition requires contradictory terms — a claim and a denial, a position and its opposite. This is not merely a pleading technicality. It reflects the deeper structural logic of common law adjudication, which requires a genuine dispute between parties before a court will act.
Historical dictionaries broadly omit "tation of suit" as a standalone entry, which is itself informative: the term did not achieve independent lexical status. Researchers should not expect to find it defined elsewhere in the standard legal dictionary corpus. The concept it points toward — issue-joining as the constitutive act of suit — is better developed under *contestatio litis* in civil law dictionaries and under "joinder of issue" in common law sources.
