Definition
In old English law and practice, plevina (also written plevinum) is the engagement, undertaking, or liability assumed by a pledge or surety on behalf of another person. It denotes the formal bond or obligation by which a pledgor or surety bound themselves to answer for the conduct, appearance, or performance of the person they stood behind. The term describes both the act of pledging and the continuing state of obligation that flowed from it.
The concept is closely tied to the medieval suretyship system, in which a surety's liability was not merely financial but was understood as a personal undertaking — a formal engagement that the surety could be released from only when the underlying obligation was discharged or when the principals consented to their release.
Common Confusion
Plevina is closely related to, but distinct from, the person who provides it. The plevina is the obligation or engagement itself; the plegius (pledge or surety) is the person who undertakes it. Conflating the two leads to imprecision when reading medieval pleading records or bractonist texts, where the distinction between the surety's status and the surety's liability is legally operative.
Why It Matters in Research
Plevina appears almost exclusively in medieval English legal materials, particularly in texts following Bracton and Fleta. Researchers encountering the term in manuscript court rolls, plea rolls, or early treatise literature should treat it as a term of art for the surety's formal engagement rather than as a generic reference to bail or security.
The Latin phrase preserved in Burrill — plegii quieti erunt de plevina, nisi gratis velint eos sub eadem plevina retinere — is significant for understanding the default rule governing surety release: pledges were automatically discharged from their engagement once the underlying obligation was satisfied unless they voluntarily chose to remain bound. This rule has implications for interpreting medieval records in which sureties appear to remain liable after what might seem to be a completed transaction.
Researchers should also note that dimissio per plevinum — release or discharge by pledge — appears in Fleta as a distinct procedural concept, indicating that plevina had an active role in the formal process of releasing persons from custody or obligation. This distinguishes it from mere security deposits and situates it within the broader medieval framework of mainprise and bail.
Because plevina is rooted in Law Latin and belongs to a procedural vocabulary that did not survive into modern common law terminology, it will not appear in post-medieval statutory sources or modern case law. Its research utility is confined to medieval and early modern legal history, bractonist scholarship, and the interpretation of historical court records.
Historical Dictionary Support
Burrill's Law Dictionary provides the primary definition and the essential supporting quotations from Bracton (fol. 149b) and Fleta (lib. 1, c. 20, § 97). Burrill correctly situates plevina within "old English practice" and identifies its core meaning as the engagement or liability of a pledge or surety. The Latin quotation from Bracton is particularly useful because it encapsulates the default rule for surety release and shows the term operating in a complete legal proposition rather than merely as an isolated label.
No other source in the present corpus covers plevina. The term is absent from modern legal dictionaries, which reflects its complete obsolescence as a working legal concept. Researchers relying solely on general legal dictionaries will find no entry; Burrill and direct consultation of Bracton and Fleta remain the necessary starting points.
Jurisdictional Note
Plevina is a term of medieval English law and has no recognized counterpart in other common law jurisdictions or in civil law systems. Its application is historically confined to England before the consolidation of modern bail and suretyship doctrine.
