Definition
An exact and faithful reproduction of an original document, instrument, or writing, intended to replicate every material feature of the original, including its form, appearance, and content. In legal contexts, "facsimile" carries two related but distinct senses:
1. Physical or documentary facsimile: A reproduction of an original instrument — a will, deed, signature, or other legal document — reproduced so precisely that it captures not only the text but the visual and physical characteristics of the original. Courts and probate proceedings have historically ordered or relied upon facsimile reproductions where the physical appearance of the original bears on its legal interpretation.
2. Transmitted facsimile (fax): A copy of a document transmitted electronically over telephone or radio networks, producing a printed image at the receiving end. In modern legal practice, "facsimile" in procedural rules, filing deadlines, and service-of-process provisions typically refers to fax transmission. Statutes and court rules may specify whether a facsimile signature or facsimile-transmitted document has the same legal effect as an original.
Common Language
Modern common usage (Wiktionary): A copy or reproduction; reproduction in the exact form as the original; a fax machine or the image it sends.
Historical common usage (Webster's 1913): "A copy of anything made, either so as to be deceptive or so as to give every part and detail of the original; an exact copy or likeness."
The common and legal meanings align closely for the general documentary sense, but the legal context sharpens the stakes: in law, a facsimile is not merely a convenient duplicate but a reproduction whose fidelity — or lack of it — may determine admissibility, authenticity, or the validity of a signature. The modern colloquial reduction of "facsimile" to simply "fax" can mislead researchers reading older legal materials, where the word has no electronic connotation whatsoever.
Common Confusion
Do not conflate facsimile with copy in the loose sense. A photocopy, carbon copy, or digital scan may qualify as a facsimile if it reproduces the original with sufficient exactness, but not all copies rise to that standard. In authentication disputes, the distinction matters: a facsimile implies a degree of precision and fidelity that "copy" does not necessarily guarantee. Separately, modern procedural rules using "facsimile" to mean fax transmission are a narrower and more recent usage; importing that meaning into older statutory or case law contexts produces anachronism.
Why It Matters in Research
The term spans two largely non-overlapping legal eras and contexts, and conflating them generates research errors.
Pre-electronic facsimile appears in probate, evidence, and document authentication contexts. Bouvier's entry points to an important and often overlooked function: English probate courts ordered that probate pass in facsimile form when the physical appearance of the will — interlineations, handwriting characteristics, paper condition, arrangement of text — might illuminate testamentary intent or authenticity. Researchers working with 19th-century probate records, wills litigation, or treatises on documentary evidence should recognize this usage and not transpose modern fax-related law onto it.
Modern facsimile (fax) law emerged primarily in the 1980s and 1990s as courts and legislatures addressed whether faxed documents satisfied statutory requirements for "writing," "signature," or "original." Procedural rules on facsimile filing, facsimile service, and facsimile signatures vary considerably by jurisdiction and by date. Court rules adopted before widespread electronic filing often contain detailed facsimile-specific provisions that have since been superseded, amended, or folded into broader e-filing frameworks. A researcher tracing the procedural history of a filing deadline or service question must check whether "facsimile" in the applicable rule meant fax transmission at the time of the relevant event.
Signature authentication is a recurring intersection point. Facsimile signatures — pre-printed or stamped reproductions of a handwritten signature — raise distinct questions from fax-transmitted handwritten signatures. Both appear in legal literature under the same term, creating potential for confusion in secondary sources.
Historical Dictionary Support
Bouvier's definition is brief but precise: "an exact copy or accurate imitation of an original instrument." The entry's immediate move to probate practice is telling — Bouvier treats facsimile as primarily a tool of documentary evidence and will construction, not a general copying concept. The probate example Bouvier gives (court ordering probate to pass in facsimile) reflects actual English Ecclesiastical Court and later Probate Division practice, where the physical form of a will could be legally significant.
What Bouvier does not address, unsurprisingly, is any electronic dimension — that layer of meaning postdates the dictionary's relevant editions by nearly a century. Webster's 1913, while not a legal source, is useful as a calibration point: it confirms that the core meaning of exact, detailed reproduction was well-established in general usage and does not require legal gloss to understand. The historical legal dictionaries are therefore most useful to researchers for the probate and authentication contexts; they offer no guidance on modern procedural or electronic-signature issues and should not be pressed to do so.
Jurisdictional Note
Whether a facsimile transmission satisfies requirements for an "original" document, a valid signature, or timely filing varies by jurisdiction and by the specific statute or rule at issue. Federal courts and state courts developed facsimile filing rules independently through the 1990s, and many of those rules were later revised or replaced by electronic filing systems. Researchers should identify the controlling rule as it existed at the time of the relevant legal event, not as it currently reads.
