Definition
An assize of fresh force was a summary common law writ available to a plaintiff who had been disseised — that is, wrongfully dispossessed of freehold land — where the dispossession had occurred within a short and recent period, traditionally forty days. The writ's defining characteristic was its speed: because the wrong was fresh, the courts could proceed on an expedited basis, with less procedural formality than an ordinary assize of novel disseisin. Like all assizes of its kind, the writ was addressed to a body of recognitors (a jury-like panel) who would determine, on a summary inquiry, whether the disseisin had in fact occurred. Relief took the form of restoration of seisin to the plaintiff.
The assize of fresh force is distinct from the broader assize of novel disseisin, which governed disseisin of any recent vintage within the ordinary limitation period. Fresh force was the more urgent remedy — reserved for the most immediate wrongs and available in certain municipal or borough courts as well as the royal courts.
Common Confusion
ASSIZE OF FRESH FORCE / ASSIZE OF NOVEL DISSEISIN: These writs are closely related and are sometimes treated as interchangeable in older secondary literature. The critical difference is timing and venue. Novel disseisin operated within a statutory limitation period set by successive acts of Parliament; fresh force was reserved for disseisin so recent — traditionally within forty days — that the circumstances of the wrong could still be freshly examined. In borough custom, fresh force had a recognized place in local court practice that novel disseisin did not always enjoy. Researchers encountering either term in historical records should not assume they name the same proceeding.
ASSIZE / WRIT: In medieval legal usage, "assize" could refer to the jury panel itself, the form of action, the proceeding, or the court sitting to hear the matter. The assize of fresh force is primarily a form of action (and the writ initiating it), not a standing court or legislative enactment. Conflating these meanings, common in non-specialist sources, will mislead corpus searches.
Why It Matters in Research
This is an obsolete writ with no modern procedural equivalent. Researchers will encounter it only in historical contexts — medieval and early modern English common law materials, borough records, and treatises on real property actions predating the reforms of the nineteenth century. Several navigational points matter:
The forty-day rule is the defining threshold. Any source discussing "fresh force" that omits or contradicts the time limitation should be read critically; some borough customs modified the period, and the rule was applied inconsistently across jurisdictions and time periods.
Borough court usage is significant. The assize of fresh force had a recognized life in municipal courts — particularly in London and other chartered boroughs — that operated with some independence from the royal courts. Corpus materials touching borough custom or city court practice may reference fresh force in contexts where royal court materials would not.
Fitzherbert's Natura Brevium is the anchor citation. Bouvier cites Fitzh. Nat. Brev. 7, and this reference to Anthony Fitzherbert's early sixteenth-century treatise on the forms of writs is the standard authority for this writ's existence and scope. When evaluating any historical source on fresh force, proximity to Fitzherbert's account is a useful indicator of reliability.
The writ disappeared from practical use well before the nineteenth-century procedural reforms, which means it will not appear in American legal materials in any operative sense. Any American dictionary entry that treats fresh force as a living writ is simply carrying forward English antecedents without updating for American practice.
Corpus researchers should also note that "force" in the phrase "fresh force" carries the older legal sense of wrongful seizure or dispossession — not physical violence in the modern sense. Word-search approaches using "force" alone will return enormous noise.
Historical Dictionary Support
Bouvier provides the most complete entry available in the Law Mind corpus: a writ of assize lying where disseisin had been committed within forty days, with citation to Fitzherbert. This is brief but accurate in its essentials. Rapalje & Lawrence's entry is fragmentary — truncated to little more than a category label — and adds nothing of substance. Neither source addresses borough court usage, the relationship to novel disseisin, or the writ's obsolescence, all of which a researcher requires for contextual understanding. The silence of both dictionaries on American practice reflects the reality that the writ was never naturalized into American law; it belonged entirely to the English common law inheritance as received and then set aside.
Jurisdictional Note
The assize of fresh force is an English common law writ with no recognized counterpart in American law. It was not adopted or adapted in American jurisdictions following independence. Researchers working in English historical materials should consult sources on borough custom and Fitzherbert's Natura Brevium; researchers in American materials will not encounter this writ in any operative context.
