Definition
The Lex Cornelia de Falso was a Roman statute enacted under the dictator Lucius Cornelius Sulla (Sylla) in the first century BCE, establishing criminal liability for forgery, counterfeiting, and related acts of falsification. It is among the foundational sources of Western law's treatment of documentary fraud and the integrity of legal instruments.
The law addressed conduct falling broadly under the Latin concept of falsum — falsification or deception — and covered a range of specific offenses including: forging or altering written instruments such as wills and legal documents; counterfeiting coins or seals; giving false testimony or suborning perjury in formal proceedings; and substituting or suppressing documents intended to have legal effect.
The statute established the quaestio de falsis, a standing criminal tribunal with jurisdiction over these offenses. Conviction under the Lex Cornelia de Falso originally entailed capital punishment or, during the later Republic and Empire, deportation and forfeiture of property for persons of free status; lesser penalties applied to those of lower social standing.

Common Confusion
The Lex Cornelia de Falso is one of several leges Corneliae attributed to Sulla's legislative program, which also included the Lex Cornelia de Sicariis et Veneficis (homicide and poisoning) and others. Researchers encountering references to "the Cornelian law" in English-language sources must confirm which statute is intended. Similarly, falsum as a concept in Roman law is broader than the English word "forgery" implies — it encompassed any deliberate falsification with legal consequence, not merely the fabrication of handwriting or signatures. Reading falsum through the narrow lens of modern forgery doctrine produces anachronistic interpretations.

Why It Matters in Research
This term appears almost exclusively in historical and comparative legal research. Researchers will encounter it in three primary contexts:
First, in treatises on Roman criminal law, the Lex Cornelia de Falso is treated as one of the quaestiones perpetuae — the standing jury courts Sulla established — alongside statutes on murder, extortion, and electoral corruption. Understanding its place within that institutional framework is essential for reading Roman legal sources accurately.
Second, in the history of forgery and fraud law, common law and civil law scholars routinely trace modern doctrines back through medieval canon law and Roman law to the Lex Cornelia de Falso. Researchers working on the development of forgery as a criminal offense, the evidentiary treatment of documents, or the law of wills and testamentary fraud will find this statute cited as a conceptual ancestor. The continuity is real but requires care: the Roman concept of falsum was considerably broader than its modern descendants, and direct analogical reasoning across the gap is a common methodological error.
Third, in civil law jurisdictions, the influence of Roman law on forgery statutes is more direct than in common law systems. Researchers comparing civilian and common law approaches to documentary fraud should treat the Lex Cornelia de Falso as a background source rather than a governing authority.
The Digest reference (Dig. 48, 10) is the primary surviving juristic material on this statute and is the source most frequently cited in secondary literature. Researchers relying on English-language summaries of that material should be aware that translations and paraphrases vary in their treatment of technical categories within falsum.

Historical Dictionary Support
Black's Law Dictionary provides a minimal entry: "In Roman law. The Cornelian law respecting forgery or counterfeiting. Passed by the dictator Sylla. Dig. 48, 10; Calvin." The citation to Calvin refers to Johannes Calvin's Lexicon Juridicum, a standard reference for Latin legal terminology in earlier centuries.
Black's entry is accurate as far as it goes but omits the breadth of the statute's coverage. Characterizing the Lex Cornelia de Falso as a law "respecting forgery or counterfeiting" captures only part of the falsum category. The statute's treatment of false testimony, suppressed documents, and will fraud is equally significant in the historical literature and in the Digest commentary.
No substantive divergence exists among the historical dictionaries on this term; the limitation is one of brevity rather than error. Researchers should treat Black's entry as a pointer to primary sources rather than a substantive account.
