Definition
Per servitium is a Latin phrase from medieval feudal law meaning "by the service" or "by reason of the service." It describes the basis by which a tenant held land from a lord — that is, by performing specified feudal services as the condition and consideration of tenure. The phrase appears most commonly in two extended forms:
Per servitia debita — "by the services due" — indicating that the tenant's obligation was defined by whatever services had been formally owed under the terms of the grant.
Per servitia antehac consueta — "by the services hitherto accustomed" — indicating that the governing standard was not a formal written specification but the customary services historically rendered, a formulation with significant practical and evidentiary implications.
Together, these phrases locate the legal relationship between lord and tenant squarely within the feudal tenure system, where land was not owned outright but held conditionally in exchange for obligations of a military, agricultural, or ceremonial character.
Common Confusion
Per servitium should not be confused with per se, which in modern legal usage means "by itself" or "inherently" and is used across tort, criminal, antitrust, and constitutional law to describe a rule or quality that attaches without need of further inquiry. The two phrases share Latin roots and a superficially similar construction but are entirely unrelated in meaning and application. A researcher encountering per se in modern case law is reading a different term altogether. Per servitium is specific to feudal tenure doctrine and has no operative modern legal meaning outside historical analysis.
Why It Matters in Research
Per servitium is archaic terminology that researchers will encounter almost exclusively in sources predating the abolition of feudal tenures — primarily in English legal materials from the medieval period through the seventeenth century, and in early American sources that analyzed or debated the reception of feudal land law. Its primary research value is interpretive: understanding what kind of tenure arrangement is being described when this phrase appears in an old grant, plea, or treatise.
The distinction between per servitia debita and per servitia antehac consueta is not merely rhetorical. The first implies a defined, documentable obligation; the second shifts the evidentiary question to custom and historical practice, which was often disputed and litigated. When reading historical title chains, conveyances, or tenure arguments, these formulations can signal the nature of the dispute — whether it turned on a written grant or on proof of long-standing usage.
American researchers should note that feudal tenure doctrine was largely abolished in the colonies and early states, though its conceptual vocabulary persisted in legal arguments about land grants, particularly those originating under English or colonial charters. The Bacon reference (Arg. Low's case of Tenures) points to Francis Bacon's legal writings, which were influential in Anglo-American tenure analysis and remained a cited authority in early American courts grappling with colonial land title questions.
This term will not appear in modern statutory codes or contemporary case law as operative doctrine. It belongs to the interpretive layer of legal history research — useful for decoding primary sources rather than for constructing modern legal arguments.
Historical Dictionary Support
Burrill's Law Dictionary is the principal secondary source providing definition and context for this term in the Law Mind corpus. Burrill's treatment is sparse but precise: it supplies the Latin phrase, translates its core variants, and anchors them with the Bacon citation. This reflects the nature of the term — it is a formulaic expression from pleading and tenure practice, not a concept requiring extended doctrinal elaboration.
What historical dictionaries do not provide is guidance on the practical evidentiary weight of the distinction between the two variant forms, or on how early American courts treated feudal tenure vocabulary when applying or rejecting inherited English land law. Researchers needing that depth must move from the dictionary entry to treatise-level sources on feudal tenure history, including Coke on Littleton and Blackstone's Commentaries, neither of which are fully replicated in the dictionary corpus.
Jurisdictional Note
Per servitium as an operative legal concept is English in origin and historically specific to common-law jurisdictions that recognized feudal tenure. In the United States, its relevance is confined to historical analysis of pre-Revolutionary and early post-Revolutionary land titles, particularly in jurisdictions where English land grants or colonial charters form part of the documentary record.
