Definition
A Latin term drawn from Roman civil law, vitium (plural: vitia) means a fault, defect, imperfection, or blemish. In legal contexts it carries two distinct applications depending on the legal tradition in which it appears:
1. Civil Law (Roman and Continental). A flaw or defect in a person, thing, or legal instrument that may affect validity, liability, or legal consequence. The term was broad enough to encompass physical blemishes in persons or animals sold under contract, defects in title or legal instruments, and moral or legal faults giving rise to liability. Roman law sources, particularly the Digest, used vitium in the context of the aedilician actions governing sales of defective slaves or animals, distinguishing a vitium (a defect or blemish) from a morbus (a disease or illness).
2. Old English Law. Fault, mistake, or error — particularly in documents or legal instruments. English legal usage narrowed the term toward clerical and scribal error, giving rise to the compound phrases vitium clerici (a clerk's error) and vitium scriptoris (a copyist's or scrivener's error), which denoted mistakes in written instruments arising from the act of transcription rather than from the intent of the parties or the judgment of the court.
Common Confusion
Vitium and morbus were formally distinguished in Roman law, a distinction that matters when reading sources from the civil law tradition. A morbus was a disease — a pathological condition impairing function. A vitium was a defect or blemish that fell short of disease: a structural imperfection, a missing limb, a physical irregularity. The aediles' edict required sellers of slaves and animals to disclose both, but the legal consequences could differ. Researchers reading the Digest on sales warranties should not treat the two terms as interchangeable, as commentators in both the civilian and common law traditions occasionally conflate them.
Why It Matters in Research
Researchers will encounter vitium almost exclusively in two documentary contexts, and the term behaves differently in each.
In civil law sources — Roman, continental European, and Scots law materials — vitium operates as a term of art for defect in the law of sale, contracts, and property. The Digest passages Burrill cites (Dig. 21.1 and Dig. 50.16.101.2) sit within the titles governing the aedilician edict on warranties in sales, which became a foundational source for civilian warranty doctrine. Researchers working in comparative law, Scots law, or Louisiana law may find vitium appearing in discussions of redhibition (the right to return a defective thing) and the actio redhibitoria. In those traditions, the vitium / morbus distinction retains practical doctrinal significance.
In common law and English legal history sources, vitium has much narrower currency. Its survival in English legal writing is almost entirely confined to the compound phrases vitium clerici and vitium scriptoris. These appear in contexts involving the correction of errors in judgments, records, and instruments — situations where courts or parties sought to reform a written document on the ground that it failed to capture the true intent due to a mechanical error of transcription. The distinction between a vitium clerici (correctable clerical error) and a substantive legal error (not so easily correctable) mattered to the availability of relief and is a live issue when reading early chancery and common law materials.
A trap for researchers: English legal sources using vitium are not invoking Roman sales law. The term migrated into English legal Latin with a narrowed meaning, and reading it through the civilian lens will mislead. Cross-check usage against the compound form (vitium clerici vs. bare vitium) to identify which tradition you are working within.
Historical Dictionary Support
Burrill's entry is compact but precise, and its value lies in clearly flagging the two distinct contexts rather than collapsing them. Burrill correctly notes the civil law sense (fault, defect, blemish, bodily defect, vice), the Digest citations, the morbus distinction, and the separate old English law sense (fault, mistake, error). The cross-reference to "Vice" and to the compound phrases is useful navigational guidance.
What Burrill does not supply — and what researchers should seek elsewhere — is the doctrinal content of the Roman law rules to which vitium attaches. For that, the Corpus Juris Civilis itself (particularly Dig. 21.1) and civilian commentators such as Pothier or Domat are the appropriate next step. For the English clerical error context, secondary sources on amendment of records at common law fill the gap.
No meaningful divergence among historical dictionaries can be assessed from the available source material, but Burrill's treatment is consistent with how the term appears in standard Roman law glossaries and Scots institutional writers.
Jurisdictional Note
In Scots law and Louisiana law — both civilian jurisdictions with Roman law foundations — vitium and related concepts (particularly vitium reale, a real or inherent defect in property) remain part of the live doctrinal vocabulary in ways they are not in English common law jurisdictions. Researchers in those systems should not treat vitium as an archaic Latin label but as a term with continuing doctrinal weight.
