Definition
A plaint is a written statement of grievance or cause of action presented to a court, used historically in English practice as the procedural mechanism by which a party initiated litigation in inferior courts without the need for an original writ. The party filing the plaint is called the plaintiff — a term that survives in modern practice long after the plaint itself has been superseded.
Two closely related senses appear in the historical sources:
1. A private memorial tendered in open court to the judge, setting forth the complaining party's cause of action. This was the foundational document of the suit in inferior courts.
2. More broadly, the exhibiting or commencing of any real or personal action in writing — the act of laying a claim before a tribunal.
In English county court procedure, the registrar entered the plaint in a designated book, formally initiating the action. This mode was particularly associated with replevin proceedings.
Common Language
Modern common usage (Wiktionary): A complaint; a lament or woeful cry; a sad song; an accusation.
Historical common usage (Webster's 1913): Audible expression of sorrow; lamentation; complaint; a mournful song. Also, an accusation or protest on account of injury, and — in a narrower legal sense — a private memorial tendered to a court setting forth a cause of action.
The common meaning of plaint centers on sorrow, lamentation, or vocal complaint. The legal meaning is procedural and documentary: a written initiating instrument filed with a court. The emotional resonance of the word in ordinary speech has no bearing on its legal function. Researchers encountering plaint in older English legal materials should resist the pull of the literary meaning and read it as a term of procedure, not of feeling.
Common Confusion
Plaint, complaint, and declaration are often used interchangeably in older sources, but they are not identical. A complaint is the modern American successor concept and carries its own procedural rules under civil procedure codes. A declaration was the formal common-law pleading document that followed the writ in superior courts — the plaint served an analogous function in inferior courts where no writ issued. The plaint should not be confused with the plaintiff's eventual substantive pleadings; it was the threshold initiating act.
Why It Matters in Research
Plaint is a term of historical English procedure that has largely disappeared from modern practice, but its traces are everywhere in the corpus. Researchers working with English common law materials, county court records, or replevin proceedings from the seventeenth through nineteenth centuries will encounter plaint as a live procedural term. Its significance lies in what it replaced and what it preserved: the plaint was the inferior-court substitute for the original writ, which was required in the superior courts of common law. Understanding this distinction is essential for reading older procedural sources accurately.
The term's most durable legacy is the word plaintiff. Every modern reference to a plaintiff is etymologically and historically rooted in the concept of the plaint — the person who makes the plaint. Bouvier makes this connection explicit, and researchers tracing the history of party designations in civil litigation should anchor that genealogy here.
Trap for historical researchers: The Rapalje & Lawrence entry under this term in the source corpus appears to contain a misalignment, covering Place Bills and placed seines rather than plaint. This is likely a digitization or pagination error in the underlying source. Researchers relying on Rapalje & Lawrence for plaint should treat that entry with caution and cross-check against Black's and Burrill's, which are consistent with each other and with Blackstone.
County court procedure under the English system standardized the plaint book as the official register of commenced actions. References to the plaint book in English procedural histories or court records indicate the formal initiation of proceedings — equivalent in function to the filing of a complaint in modern American practice.
Historical Dictionary Support
Black's, Burrill's, and Anderson's are in close agreement, all tracing the plaint to Blackstone's Commentaries (3 Bl. Comm. 373) and Stephen's Commentaries (3 Steph. Comm. 666), identifying it as a proceeding in inferior courts to commence an action without original writ. This consistency reflects that by the time these dictionaries were compiled, plaint was already a historical term being defined rather than a living procedural tool being used.
Bouvier adds the broader framing — the exhibiting of any action, real or personal, in writing — and explicitly draws the etymological line to plaintiff, noting the French root pleyntife. This broader framing is useful: it positions the plaint not merely as a county court artifact but as the general concept underlying the plaintiff's role across forms of action.
Anderson's is notably spare, adding only that plaint is "preserved in complaint and plaintiff" — a concise acknowledgment that the term's functional life has ended but its linguistic legacy endures.
What the historical dictionaries collectively miss: none of them adequately address the transition from plaint-based inferior court procedure to the reformed civil procedure of the nineteenth century, particularly the impact of the County Courts Act 1846 and subsequent procedural reforms that standardized and eventually displaced the plaint as a distinct procedural category. Researchers tracing that transition will need to move beyond the dictionary sources to the procedural histories themselves.
Jurisdictional Note
Plaint as a distinct procedural term is specific to English law and has no direct American equivalent. American jurisdictions adopted complaint as the initiating pleading under code pleading and later the Federal Rules of Civil Procedure. Researchers working in colonial American materials may encounter plaint in early proceedings modeled on English inferior court practice, but the term was not carried forward into American procedural codes.
