Definition
A single original is a legal instrument executed as one unique copy rather than in duplicate or multiple counterparts. Where parties sometimes execute an agreement by signing separate but identical copies — each of which is treated as an original — a single original is executed only once, producing one authoritative document. The executed instrument itself, rather than any copy or counterpart, constitutes the sole original record of the transaction.
Common Language
Modern common usage (Wiktionary): "Single" means alone, individual, or unaccompanied. "Original" means the first or primary form of something, as distinguished from a copy.
Historical common usage (Webster's 1913): "Original" is defined as "that which precedes all others of its class; the first copy of a writing, as opposed to a transcript."
The legal meaning does not so much conflict with common understanding as sharpen it. In ordinary speech, calling a document "the original" simply means it is not a photocopy. In legal usage, "single original" specifically distinguishes an instrument executed once in a single instance from one executed in duplicate or counterparts — the contrast is not between original and copy, but between one-document execution and multi-document execution.
Common Confusion
SINGLE ORIGINAL vs. DUPLICATE ORIGINALS / COUNTERPARTS: When parties sign separate but identical copies of an agreement, each signed copy is a "duplicate original" (or executed "counterpart"), and collectively they form one binding agreement. A single original, by contrast, exists as only one executed instrument. Modern commercial contracts routinely authorize execution in counterparts, making duplicate originals the norm. Researchers reviewing historical instruments should not assume that the absence of a counterparts clause means the document is unique — it may simply reflect an era when single originals were the default.
Why It Matters in Research
The concept of single original is most consequential in document authentication, chain-of-custody analysis, and evidentiary questions about best evidence. Researchers working with historical instruments in the Law Mind corpus should note:
Best evidence rule implications: Courts historically required production of the "original" instrument. Where an agreement was executed as a single original, loss or destruction of that document created evidentiary problems that would not arise with duplicate originals. Pleading and proof records from the 18th and 19th centuries often turn on this distinction.
Notarial and recording practice: Deeds, wills, and conveyances were commonly executed as single originals and then recorded (with the record copy serving as public evidence of the instrument's existence). The original might remain with the grantor, grantee, or notary depending on jurisdiction and era. Researchers tracing title or probate chains must distinguish between the executed original, the recorded copy, and certified copies — each has different evidentiary weight in historical sources.
Shift to counterparts: The rise of commercial practice, and later electronic commerce, made execution in counterparts standard. Modern statutes and the Uniform Electronic Transactions Act (UETA) address what constitutes an "original" in electronic contexts. Historical sources predating this shift use "single original" as the assumed baseline, not a marked category.
Sparseness of definition in sources: Because the single original was simply the ordinary mode of execution for most of legal history, historical dictionaries treat it almost as a residual category — defined only in contrast to duplicate originals. Researchers should not read its brevity in the sources as indicating minor importance; it was the default, unremarkable form.
Historical Dictionary Support
Black's Law Dictionary offers a compact, functional definition: "An original instrument which is executed singly, and not in duplicate." This is characteristic of Black's treatment of procedural and documentary terms — accurate but spare, with no treatment of evidentiary consequences or historical evolution.
No additional source dictionaries were available for this entry. The definition in Black's is consistent across editions and reflects the term's stable, technical use. What the historical sources collectively omit is any discussion of why the distinction matters — the connection to best evidence doctrine, notarial practice, and the transition to counterpart execution is not addressed in dictionary form and must be assembled from treatise and case sources.
