Definition
An archaic legal term of medieval English origin referring to pre-emption — the right or practice of purchasing goods before they are offered to the general market. The term is closely associated with forestalling the market, a common law offense involving the interception of goods or merchants before they reached an open market, thereby manipulating prices or supply to the detriment of ordinary buyers and the public market order.
In historical usage, forcheapum described the act of buying up goods ahead of market availability, giving the buyer an artificial advantage inconsistent with fair trading norms enforced under medieval market regulation.
Common Confusion
Forcheapum is sometimes loosely grouped with related market offenses — engrossing (buying up large quantities of a commodity to control its price) and regrating (buying and reselling in or near the same market at a higher price) — but it is distinct. Forcheapum specifically concerns the pre-market interception or pre-emptive purchase, not the cornering of supply after market entry or the resale markup. Researchers should not treat these three offenses as interchangeable; medieval and early modern legal records treat them as separate wrongs, even when charged together.
Why It Matters in Research
This term appears almost exclusively in historical and antiquarian legal sources and has no operational role in modern law. Researchers encountering forcheapum will find it in records touching medieval market regulation, borough charters, fair courts, and early treatises on common law trade offenses.
Several research traps apply:
First, the term is sparsely indexed. Black's (both editions) define it only by cross-reference to Jacob's Law Dictionary and the concept of forestalling, with no substantive elaboration. Bouvier similarly offers only a one-word gloss. A researcher relying solely on these definitions will miss the broader regulatory context in which the offense functioned.
Second, the spelling is unstable across historical sources. Latin and Anglo-Norman legal manuscripts render the root in various forms, and the -cheapum element connects to the Old English term for bargain or market (cognate with "cheap" in place names like Cheapside). Researchers searching period records should use variant spellings and root terms.
Third, the offense of forestalling — the modern gloss applied to forcheapum by Black's and Bouvier — had a long independent legal history in English statute and common law before being formally abolished in England in the nineteenth century. Treating forcheapum as merely a synonym for forestalling elides distinctions that may matter in close historical analysis of a specific document or proceeding.
The term connects within the Law Mind corpus to entries on forestalling, pre-emption, engrossing, and regrating, as well as to encyclopedia material on market regulation and trade offenses in English legal history.
Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) are in agreement, defining forcheapum identically as "pre-emption; forestalling the market" and citing Jacob's Law Dictionary as authority. Bouvier echoes this with equal brevity, adding only the citation to Blount — a reference to Thomas Blount's Nomo-Lexicon (1670), which is among the earliest English legal dictionaries to record the term.
None of the three historical sources provides analytical content beyond the bare gloss. They agree on meaning but offer no guidance on how the offense was prosecuted, what courts had jurisdiction, what penalties applied, or how it related to the broader statutory scheme governing market offenses. This is a case where the historical dictionaries function as placeholders rather than authorities — they confirm the term existed and gesture at its meaning, but the substantive legal history must be recovered from primary sources and specialist scholarship on medieval trade law.
Blount's Nomo-Lexicon is the foundational source underlying all three dictionary entries and is the most instructive starting point for any researcher pursuing the term beyond the modern dictionary shelf.
Jurisdictional Note
Forcheapum is a term of English common law and has no recognized counterpart or usage in American, Scottish, or continental legal traditions. American legal dictionaries include it only as a historical import. Researchers working in American legal history will not encounter it in operative legal instruments.
