Definition
To falsify is to make something false, to prove something false, or to show that a recorded item is wrong. The term carries three distinct legal senses that must be distinguished by context:
1. To forge or counterfeit. To create or alter a document, record, instrument, or other item with intent to deceive. This is the primary criminal and regulatory sense. A person who falsifies business records, financial statements, or official documents commits an offense under most modern criminal codes.
2. To disprove or defeat. In older procedural usage, to falsify a verdict, appeal, or judgment meant to demonstrate it was erroneous and thereby avoid or reverse it. This sense is largely historical and has been displaced by modern appellate vocabulary.
3. To show an account item to be wrong (equity practice). In chancery proceedings, to falsify a charge in an account meant to demonstrate that a particular item debited against a party was either entirely false or in some part erroneous — without necessarily reopening the whole account. This is the technical equity sense, closely paired with the right to surcharge.

Common Language
Modern common usage (Wiktionary): To alter so as to make false, especially with intent to deceive; to misrepresent; to counterfeit or forge; also, to prove something to be false.
Historical common usage (Webster's 1913): To make false; to represent falsely; to counterfeit or forge; and also to prove to be false or untrustworthy, to confute or nullify.
Editorial note: The common meaning tracks two of the three legal meanings closely — forging and disproving — but entirely misses the technical equity sense. A researcher encountering "falsify" in a chancery accounting context who reads it as mere forgery will fundamentally misread the passage. The equity sense is narrow, procedural, and carries no suggestion of criminal fraud; it simply means identifying a bookkeeping entry that does not belong.

Common Confusion
The criminal/forgery sense and the equity accounting sense are frequently conflated by researchers reading historical materials. In criminal law, to falsify implies fraudulent intent and is the basis for prosecution. In equity practice, to falsify a charge in an account is a neutral procedural act — counsel for the accounting party identifies an item as incorrectly included. The same word in two adjacent paragraphs of an 18th-century treatise may carry entirely different weight depending on whether the context is chancery accounting or criminal pleading. Separately, do not confuse falsify (active alteration or demonstration of error) with surcharge (showing that an item was omitted from an account). The two rights — to surcharge and to falsify — are granted together as a pair but address opposite accounting errors: omission versus wrongful inclusion.

Recognized Forms
/SUBTYPES
Surcharge and falsify: A paired equitable remedy allowing a party challenging a settled account to (a) surcharge — show that credits or receipts were omitted — and (b) falsify — show that debits were improperly included — without requiring the court to tear open and restate the entire account from scratch. The party challenging the account bears the burden of demonstrating specific errors rather than requiring the accounting party to re-prove everything.
Falsification of records: The modern statutory offense of altering, destroying, or fabricating business records, public records, or official instruments with fraudulent intent. Often treated as a distinct crime from forgery in contemporary penal codes, though the concepts overlap significantly.

Why It Matters in Research
The three-sense problem is the central research trap. In primary sources from the 17th through 19th centuries, "falsify" can appear in criminal pleadings, chancery accounting proceedings, and appellate argument in quick succession — with different meaning in each context. Reading chronologically within a single document is not enough; the researcher must identify the procedural posture of every passage.
The equity accounting sense is underrepresented in modern legal vocabulary. Researchers trained on contemporary sources may never encounter "surcharge and falsify" as a paired doctrine and will not recognize it when it appears in historical chancery records, master's reports, or equity treatises. Bouvier and Rapalje give this sense more space than Black's first edition, making them better starting points for equity research.
The "disprove or defeat" sense — falsifying a verdict or judgment — is almost entirely historical. It appears in Coke, Blackstone, and Littleton citations but has no surviving procedural equivalent. Researchers reading early English common law materials or 18th-century American practice should flag this usage and not transpose modern criminal or accounting meanings onto it.
In regulatory and white-collar criminal research, falsify appears constantly in statutes and agency rules governing financial records, securities disclosures, and government documents. The term is often undefined in the statute itself and interpreted by courts with reference to common law forgery principles and the specific regulatory context. Jurisdictional variation in what counts as sufficient "falsification" — particularly regarding intent requirements — is significant.
Corpus connections: Researchers working in chancery records should cross-reference ACCOUNT, MASTER IN CHANCERY, and SURCHARGE. Researchers in criminal and regulatory contexts should cross-reference FORGERY, FRAUD, and FALSE STATEMENT.

Historical Dictionary Support
The historical dictionaries converge on the three-sense structure but weight the senses differently. Burrill gives the Latin and Law French roots and emphasizes the "prove false / avoid or defeat" sense with common law citations to Coke and Blackstone. Bouvier privileges the equity accounting sense and provides the fullest treatment of surcharge-and-falsify procedure. Black's second edition is the most complete single entry, expressly including all three senses — forging, disproving, and chancery accounting — and is the best historical reference for a researcher who needs to identify which sense is operative.
Black's first edition gives only the "disprove / avoid or defeat" sense, which understates the criminal forgery dimension that had already become prominent by the late 19th century. Researchers relying solely on the first edition will miss that gap.
No historical dictionary adequately covers the regulatory falsification offenses that proliferated in the 20th century — falsifying SEC filings, federal records, tax documents, and government contracts. For those, statutory text and case law must carry the load; the shelf sources provide background only.
Webster's 1913 is notably accurate here: it independently captures both the "make false / forge" and "prove to be false" senses, which aligns well with the legal record and can serve as a useful sanity check when a passage's legal context is ambiguous.

Jurisdictional Note
The criminal offense of falsifying records is defined by statute in every U.S. jurisdiction, but the elements — particularly intent requirements and what qualifies as a "record" or "document" — vary substantially. Federal law addresses falsification in multiple overlapping statutes depending on the type of document involved. The equity doctrine of surcharge and falsify, where it survives, has been absorbed into modern accounting and discovery practice and rarely appears by name outside historical proceedings.
