Definition
Ex scriptis olim visis (Latin: "from writings formerly seen") is a evidentiary standard describing one recognized method by which a witness may establish familiarity with another person's handwriting for purposes of authenticating a document. Under this standard, the witness's knowledge of the handwriting is derived not from direct instruction or side-by-side comparison, but from having previously seen writings purporting to be in the hand of the person in question, and having subsequently acted upon those writings — either by communicating directly with that person about the contents, or by responding in writing — in a manner that reasonably confirms the attribution.
The phrase identifies the specific epistemic foundation for the witness's testimony: the witness saw the writings, treated them as genuine in the ordinary course of affairs, and that course of dealing supplies the basis for an opinion that the writing in question came from the same hand.

Common Confusion
Ex scriptis olim visis is one of several Latin formulas used to classify the permissible grounds for handwriting testimony. It should not be conflated with proof by direct comparison (where the witness watched the party write), nor with proof arising purely from reputation or official record. The distinction matters because courts and treatises historically used these Latin categories to assess whether a witness's foundation was sufficient to be received at all — not merely to weight the testimony once admitted. A researcher encountering one formula in a historical opinion or pleading should not assume the others are interchangeable.

Why It Matters in Research
This phrase appears almost exclusively in older common law sources — primarily English and early American — dealing with the authentication of private documents. Researchers working with 18th and 19th century trial records, evidence treatises, or appellate opinions on document authentication will encounter it as a term of art describing the admissibility threshold for handwriting witnesses, not merely a descriptive label.
The practical trap: modern evidence law has largely dissolved the formal categorical distinctions that Latin phrases like this one encoded. Federal Rule of Evidence 901(b)(2) permits lay opinion on handwriting based on familiarity "not acquired for purposes of the litigation," without requiring the witness to identify which classical category their knowledge falls into. A researcher reading a 19th century ruling that a witness was competent ex scriptis olim visis should understand this as a finding about the specific legal adequacy of a particular type of prior familiarity — a finding that modern doctrine absorbs into a more general inquiry but would not frame in these terms.
The phrase also signals the procedural context in which handwriting proof was treated as a preliminary legal question (going to admissibility) rather than a factual one (going to weight). That distinction has practical consequences when tracing how handwriting authentication doctrine evolved from a gatekeeping rule into a sufficiency standard.
Corpus connections: this term will appear alongside related authentication vocabulary — comparison aliunde, attesting witness, proof of execution — and in the same sources that discuss the broader taxonomy of handwriting evidence. Gilbert's Law of Evidence and Starkie's Treatise on Evidence are the treatise sources most likely to use this classification system in depth.

Historical Dictionary Support
Both Black's editions define the phrase identically in substance, with the second edition adding only the Latin gloss "From writings formerly seen." The definition is stable across both sources: the witness must have seen documents purporting to be the party's handwriting, and must have subsequently communicated with the party about those documents or otherwise acted on them — as by a written reply.
What the dictionary entries do not address is why the subsequent communication or reliance matters. The doctrinal logic is that such conduct supplies independent corroboration that the writings were, in fact, the party's: if the party responded to a letter without objecting that it misrepresented what they had written, or if correspondence proceeded on the assumption of authenticity, that course of dealing tends to confirm the attribution. The knowledge is not merely visual recognition but recognition validated by conduct.
Historical dictionaries are silent on the question of how courts handled witnesses who saw the writings but never had occasion to act upon them — a gap that practitioners and scholars addressed through other doctrinal categories. Researchers should not assume that ex scriptis olim visis was the only, or even the most common, basis for admitting handwriting testimony; it was one recognized category in a structured system that also included witnesses who had seen the party write and those with official or business knowledge of the handwriting.

Jurisdictional Note
The Latin classification system this phrase belongs to was primarily an English common law construct. American courts adopted the underlying doctrine but varied in how strictly they applied categorical distinctions. By the late 19th century many American jurisdictions were collapsing the categories into a general familiarity standard. Researchers should check whether the jurisdiction in question was still applying formal categorical analysis at the time of the source they are reading.
