Definition
A Latin term from Roman law meaning a previous act or thing done before. *Antegestum* refers to a prior act or transaction that has legal bearing on a subsequent matter — typically used to describe antecedent conduct relevant to interpreting or adjudicating a later legal question.
The term operates as a descriptor rather than a doctrine: it names the category of prior act without prescribing what legal consequence follows from it. Its significance in any given context depends on what rule or principle attaches legal weight to prior conduct.

Why It Matters in Research
This is a narrow term of Roman law origin with limited survival into modern common law sources. Researchers encountering *antegestum* will almost always be working in civil law materials, Roman law texts, or early jurisprudential writing that draws on the Digest.
The principal research trap is assuming the term carries a defined doctrinal content of its own. It does not function like a cause of action or a legal standard. When *antegestum* appears in a source, the researcher's task is to identify what the surrounding legal rule does with the prior act — whether it bars a claim, modifies liability, establishes intent, or serves some other function. The term labels the temporal relationship; the legal consequences come from the surrounding framework.
Researchers working in civil law jurisdictions or comparative law contexts should note that the concept of antecedent acts shaping legal outcomes is well-developed in both Roman and modern civil law systems, though the term *antegestum* itself rarely appears in contemporary civil codes or commentary. It is most useful as a finding aid when tracing historical doctrinal arguments through classical and humanist legal writing.
The Digest citations in Burrill (38.1.40 and 48.23.3) anchor the term in Roman sources. Dig. 38.1 concerns the duties of freedmen (*operae libertorum*), and Dig. 48.23 concerns the restoration of rights (*restitutio in integrum* and related matters). The appearance of *antegestum* in both a private law and a public/criminal law context suggests the term was a general descriptor used across different areas of Roman legal writing rather than a term of art confined to one field.

Historical Dictionary Support
Burrill's Law Dictionary provides the sole identified historical dictionary entry for this term. Burrill defines it straightforwardly — "a thing done before; a previous act" — and supplies the Latin construction (*ante*, before + *gestum*, done) along with two Digest citations without further elaboration.
The brevity of Burrill's entry is itself informative: this is not a term that attracted extended commentary in the Anglo-American legal dictionary tradition. Its presence in Burrill reflects the nineteenth-century practice of cataloguing Roman and civil law terms as part of a comprehensive legal lexicon, not evidence that the term was in active use in common law courts or pleading.
No comparable entry has been identified in other major historical law dictionaries surveyed. The absence of the term from sources like Black's early editions or Bouvier's reinforces its character as a learned borrowing rather than an operating term of common law practice.
