Definition
De hsquitate (also rendered de aequitate or de aquitate in historical sources) is a Latin phrase meaning "in equity" or "according to equity." It appears in legal texts to contrast equitable rights or claims with rights enforceable at strict law. The phrase signals that a party has no remedy or entitlement under the rigid rules of the common law but may nonetheless obtain relief through the equitable jurisdiction of a court of conscience.
The phrase is most familiar in its classical formulation drawn from Fleta: de jure stricto, nihil possum vendicare, de aquitate tamen, nullo modo hoc obtinet — "in strict law, I can claim nothing, but in equity this by no means obtains." The statement encapsulates the foundational tension between ius strictum (strict law) and aequitas (equity): where the letter of the law denies a remedy, equity may supply one.
Common Confusion
The variant spellings in historical sources — de aequitate, de aquitate, de hsquitate — are not distinct legal terms. They reflect scribal variation, typographic corruption in early printed texts, and inconsistent transliteration of the Latin ae ligature (æ). Researchers encountering "de hsquitate" in a source should treat it as a corrupted or archaic rendering of de aequitate. The "hs" combination is a recognized typographic artifact of early modern printing, where the æ character was misread or misset. Do not treat the variants as terms of art with separate meanings.
Why It Matters in Research
The primary research challenge here is recognition. A researcher encountering "de hsquitate" in a historical legal text may not recognize it as a form of de aequitate and may fail to connect it to the broader body of equity jurisprudence. This is a textual artifact problem, not a doctrinal one.
Several specific traps exist for corpus researchers:
First, early printed editions of Fleta and similar medieval treatises were reproduced with variable fidelity. The Law Mind corpus may contain multiple printings of the same source text with divergent spellings of the same phrase. A keyword search for "de aequitate" will not surface instances rendered as "de hsquitate" or "de aquitate" unless the search is constructed to account for the variation.
Second, the phrase appears almost exclusively in learned and academic legal writing — treatises, commentaries, and Latin maxim collections — rather than in case reporters or statutes. Researchers looking for the underlying doctrine (equitable relief where strict law fails) will find it expressed in English-language opinions without the Latin tag. The Latin form is a signal of source type, not of a distinct doctrinal rule.
Third, the substantive doctrine the phrase encodes — that equity intervenes where strict law produces unjust results — is foundational to the entire equity tradition. Researchers who find this phrase in a historical source should treat it as an entry point into a much larger body of equitable jurisprudence, not as a self-contained rule.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) Supplemental is the sole source dictionary providing a formal entry, and it is brief. The entry reproduces the Fleta passage without elaboration, suggesting that by the time of Black's second edition, the phrase was already primarily of antiquarian interest — a Latin tag useful for locating the classical statement of equitable jurisdiction rather than a term in active doctrinal use.
The Fleta passage itself (lib. 8, c. 2, t. 10) dates to the late thirteenth century and represents one of the earliest systematic attempts to articulate the distinction between legal and equitable entitlement in English legal literature. The phrase thus carries historical weight disproportionate to its brevity. Historical dictionaries generally treat it as a maxim of equity rather than a term of art, which is the correct framing.
No substantive divergence among historical sources is noted, because the source base here is essentially a single transmitted text. The variation is orthographic, not interpretive.
