Definition
To withhold lands or tenements from their rightful owner. The term describes the act of a person — a deforciant — who holds real property against the legitimate claim of another, not necessarily through force or fraud, but simply by refusing to yield possession to the person entitled to it. Deforciare is a term of art in the law of real property and conveyancing; it cannot be replaced by any synonym without altering the legal meaning.
Common Confusion
Deforciare should not be confused with disseisin or dispossession, though all three involve a person being kept from property. Disseisin implies an actual ouster — the rightful owner was once in possession and was displaced. Deforciare more broadly covers the withholding of property from one entitled to it, including situations where the claimant has not yet entered into possession. The distinction mattered in common law pleading, where the choice of word carried procedural consequences.
Why It Matters in Research
This term appears almost exclusively in older English common law sources and early American materials that drew directly from those sources. Researchers encountering it in historical documents — writs, pleadings, conveyancing records, or abridgments — should understand that it functions as a fixed term of art, not a descriptive phrase. Coke's authority (Co. Litt. 331b) for the proposition that no other word can supply its meaning was taken seriously by pleaders and courts: substituting a near-synonym in a writ or declaration could prove fatal to the action.
The term connects to a cluster of abolished real actions — formedon, mordaunt ancestor, writ of right, and related possessory and proprietary writs — that were the primary vehicles for resolving land title disputes before ejectment displaced them in practice and before the Real Property Limitation Acts and their American equivalents cleared much of the procedural landscape. Researchers working in colonial American land records, early state court archives, or English chancery and common pleas materials will encounter the term and its noun form, deforciant, with some regularity.
Modern legal research tools often fail to surface this term because it rarely appears in post-nineteenth-century materials. Keyword searches should include variant spellings and the noun forms: deforciant, deforcement, and the anglicized deforce.
Historical Dictionary Support
All four source dictionaries agree on the core definition: deforciare means to withhold lands or tenements from the rightful owner. Black's (both editions) and Bouvier each transmit Coke's caveat that the word is irreplaceable as a term of art — Bouvier adding support from Bracton and Fleta, which extends the pedigree of the term deep into medieval English jurisprudence. Rapalje & Lawrence offer the same substance in abbreviated form, omitting the term-of-art observation.
What the historical sources do not do is situate the term within the procedural machinery it served. None explains which writs employed it, how the deforciant's position differed from that of a disseisor, or why the courts treated it as incapable of substitution. Researchers should look beyond dictionary entries to Coke on Littleton directly and to Blackstone's treatment of the real actions for that procedural context.
Jurisdictional Note
Deforciare is a term of English common law origin and has no independent life in modern American statutory law. Its appearance in American legal materials is historically bounded — most heavily concentrated in the colonial period and the early republic, where English pleading forms were still in use. By the mid-nineteenth century, the real actions in which the term functioned had largely been abolished or fallen into disuse across most American jurisdictions.
