Definition
A Law French adverbial phrase meaning "in the future" or "for the time to come." Used in older legal instruments and judicial writings to indicate prospective operation — that a rule, obligation, or legal effect runs forward from a given point rather than backward. The phrase functions as a temporal qualifier, signaling that what follows applies to future circumstances rather than past or existing ones.
Common Language
Modern common usage (Wiktionary): "En avant" is a French phrase meaning "forward" or "onward," used in general speech to urge progress or movement ahead.
Historical common usage (Webster's 1913): Not entered as a distinct headword; the component words "en" and "avant" carry the ordinary French senses of "in" and "before/forward."
The gap between ordinary and legal usage is modest but worth noting. In common French, the phrase emphasizes directional movement or encouragement. In legal usage, it is strictly temporal — it designates future legal operation, not motion or exhortation. A reader encountering the phrase in a legal instrument should not read it as rhetorical flourish but as a precise indicator of prospective effect.
Common Confusion
EN AVANT is occasionally conflated with the Latin phrase IN FUTURO, which carries essentially the same meaning. Both signal prospective legal operation, and in practice the two phrases were used interchangeably in older English legal sources. The distinction is purely one of linguistic register: EN AVANT is Law French; IN FUTURO is Latin. Neither carries a substantive legal difference, but researchers should search both forms when working through historical materials, as a given scribe or reporter may have preferred one over the other without signaling the substitution.
Why It Matters in Research
EN AVANT appears almost exclusively in pre-modern sources — English Year Books, early chancery records, and treatises from the period when Law French remained the working language of the English common law courts. By the eighteenth century the phrase had largely given way to English equivalents or the Latin IN FUTURO, so its density in the corpus is heavily weighted toward medieval and early modern materials.
Two practical traps exist. First, transcription and translation inconsistency: manuscript sources sometimes render the phrase as "en avent" or "en avaunt," reflecting variation in Law French orthography. A researcher relying on keyword search alone may miss occurrences spelled differently. Second, context sensitivity: the phrase does not itself specify the triggering date from which futurity runs. That anchor must be found in the surrounding text. A grant operative "en avant" from a feast day, a judgment, or a statute's enactment will have different practical reach depending on which anchor the instrument uses.
For researchers working in property law history, the phrase appears in conveyancing contexts where grantor and grantee needed to distinguish between rights vesting immediately and those arising from a future date. In statutory construction materials, it sometimes appears in glosses distinguishing prospective from retrospective legislation — a distinction with enduring constitutional relevance even if the phrase itself is archaic.
Historical Dictionary Support
Burrill's Law Dictionary is the single shelf source here, and its entry is spare: "In future; for the time to come," with attribution to Kelham's Norman-French dictionary. Burrill does not elaborate on how the phrase operated in specific legal contexts, which is characteristic of his treatment of Law French particles and phrases — he records meaning without contextual instruction.
Kelham's Dictionary of the Norman or Old French Language (1779), to which Burrill refers, is the primary philological authority for this class of term. Researchers who need the fuller linguistic history of the phrase should consult Kelham directly rather than relying on Burrill's compressed citation. No major disagreement exists between available sources on the core meaning; the phrase is unambiguous and was not a site of legal controversy in the way that substantive terms of art often were.
What historical dictionaries collectively omit is any guidance on the phrase's relationship to prospective-versus-retrospective legal doctrine more broadly — a gap the researcher must fill by moving from the dictionary shelf to doctrinal sources.
Jurisdictional Note
EN AVANT is a term of English legal history and does not appear as a term of art in American or Scottish legal materials with any frequency. Researchers working in American legal history will encounter it only in sources that explicitly draw on early English common law, and then typically in quoted or reprinted English texts rather than as native American usage.
