Definition
In old English and medieval Latin legal usage, acquietare means to acquit, discharge, or release a person from a debt or obligation. The term appears in Latin instruments and writs of the medieval English common law, where it functioned as the operative verb directing that one party be freed from a financial claim or demand. A typical formulation ran: quod acquietet B. de viginti solidis — that he acquit B. of twenty shillings.
The term is not in active use in modern legal writing. It survives principally as a Latin relic in historical legal instruments, Year Books, and early common law records.
Common Confusion
Acquietare should not be confused with acquittance (the noun form documenting a discharge of debt) or with acquittal (the verdict of not guilty in a criminal proceeding). The three terms share a common Latin root but operate in distinct legal contexts. Acquietare is the verbal command in an instrument; acquittance is the documentary evidence of a completed discharge; acquittal belongs to criminal procedure entirely. Researchers encountering any of these terms in historical records should confirm which form and context applies before drawing conclusions about the legal effect intended.
Why It Matters in Research
Researchers working in medieval English legal manuscripts, plea rolls, charter records, or early common law writs will encounter acquietare as a functional term of art in Latin instruments. Its significance is primarily paleographic and interpretive: when the verb appears, it signals that the instrument is operative as a release or discharge, and the researcher must identify what obligation is being extinguished and in whose favor.
Two research traps are worth flagging. First, the term's resemblance to the modern English acquit can mislead researchers into reading a debt-discharge instrument as a criminal acquittal or general release of liability — these are distinct legal acts. Second, because acquietare belongs to the Latin layer of medieval English law, it may not appear in English-language indexes or calendars of records that paraphrase or translate the underlying Latin. Researchers relying on English-language calendars alone may miss instruments in which acquietare is the operative verb.
The term connects to the broader cluster of medieval conveyancing and debt concepts, including quietum clamare (to quitclaim), acquittance, and the range of instruments by which feudal and commercial obligations were formally extinguished. Understanding acquietare in context requires familiarity with how medieval scribes structured debt instruments and the conventional Latin formulae they employed.
Historical Dictionary Support
Burrill's Law Dictionary is the sole dictionary source for this entry, and its treatment is brief but precise. Burrill traces the term to ad + quietare, glossing the underlying concept as making someone quit or free from molestation — that is, putting a matter at rest so that the obligee has no further claim. He supplies the example quod acquietet B. de viginti solidis and cross-references Spelman's Glossarium Archaeologicum under Acquietantia.
Burrill's derivation is consistent with the broader family of quietus and quitclaim terminology that runs through medieval English law. The gloss "to give quiet" is instructive: the conceptual core of acquietare is not merely formal cancellation of a debt but the assurance of peace — freedom from future pursuit by the creditor. This nuance distinguishes a mere receipt from a formal discharge and explains why the term appears in operative clauses of instruments rather than in recitals.
No other Law Mind shelf dictionaries supply additional entries for this term. Researchers needing deeper treatment should consult Spelman's Glossarium directly, as well as Du Cange's Glossarium Mediae et Infimae Latinitatis for broader medieval Latin context.
Jurisdictional Note
Acquietare is specific to the medieval English common law tradition and its Latin documentary practice. It does not appear as a term of art in Scottish, continental European, or ecclesiastical law records in the same operative sense, though cognate forms exist in medieval Latin instruments across jurisdictions. Researchers working in non-English archives should treat apparent cognates with care and verify local usage.
