Definition
A Latin term from the civil and common law meaning "impersonality" — a mode of expression in which no specific person is identified or named. In legal usage, impersonalitas describes language that speaks in general or passive terms, making no reference to any particular individual. The classic example is the phrase *ut dicitur* ("as is said"), which attributes a statement to no one in particular.
The doctrine embedded in the associated maxim — *impersonalitas non concludit nec ligat* ("impersonality neither concludes nor binds") — carries the operative legal weight: language that identifies no specific person cannot create a binding obligation on, or a conclusive finding against, any particular party. An impersonal expression in a legal instrument or pleading does not estop or bind anyone because it commits to nothing about anyone specifically.
Common Confusion
Impersonalitas should not be confused with anonymity or with the modern concept of a "John Doe" pleading. Anonymity concerns the concealment of a known identity; impersonalitas concerns language that is structurally depersonalized — it names no one not because an identity is hidden, but because the expression makes no personal attribution at all. Similarly, the term should not be conflated with the concept of impersonal obligations in civil law (obligations attaching to property or office rather than a person), which is a distinct doctrine.
Why It Matters in Research
This term is almost exclusively encountered in older common law sources and in materials tracing the influence of Coke's *Institutes* on Anglo-American legal doctrine. Researchers will find it cited principally in discussions of pleading precision and the binding effect of language in deeds, judgments, and other formal instruments.
The maxim *impersonalitas non concludit nec ligat* was invoked to police vagueness in legal instruments: a document that spoke impersonally — failing to name the party bound or the party benefited — could not be enforced as if it had done so. This had practical consequences in deed construction and in the interpretation of recitals. A recital couched in impersonal terms (*ut dicitur*, "it is said," "as reported") could not serve as an admission binding a named party, because the impersonal form committed no one to the statement.
For corpus researchers working in early modern English legal materials, this term is a signal that the surrounding discussion concerns either (1) the sufficiency of a pleading or instrument in identifying the parties it purports to bind, or (2) the evidentiary weight of recitals and hearsay-like expressions in formal documents. It frequently appears in proximity to discussions of estoppel by deed, the effect of recitals, and pleading certainty.
The term effectively disappears from active legal usage by the nineteenth century. Modern pleading doctrine addresses the same underlying concerns through rules requiring identification of parties and through hearsay doctrine, but uses entirely different vocabulary. Researchers should not expect to find *impersonalitas* in post-1850 primary sources except as a historical reference.
Historical Dictionary Support
All four source dictionaries — Black's (both editions), Burrill, and Bouvier — converge tightly on the same definition, the same illustrative phrase (*ut dicitur*), and the same Coke citation (Co. Litt. 352b). This uniformity reflects the fact that all four are drawing from the same original source: Coke's *Institutes*, specifically the commentary on Littleton's *Tenures* at folio 352b. There is no meaningful divergence among the dictionaries on substance.
Burrill and Bouvier reproduce the maxim in the same form. Black's (1st ed.) and the 2nd edition are textually nearly identical, with only minor typographical differences reflecting transcription from the original folio page.
What the historical dictionaries collectively omit is any explanation of how the principle operated in practice or what consequences followed when an instrument was found to speak impersonally. They record the maxim and its translation without doctrinal elaboration. Researchers seeking application rather than definition must go to Coke directly or to treatises on pleading and the construction of deeds from the sixteenth through eighteenth centuries.
Jurisdictional Note
This is a common law term derived from Coke's *Institutes* and belongs primarily to the English legal tradition. It has no distinct American statutory or constitutional dimension, and American courts did not develop independent doctrine around the term. Its relevance in American legal research is essentially historical.
