Definition
To make a sworn statement in writing; to depose. In its strict legal sense, depone is a term drawn from Scots law meaning to give sworn testimony, particularly in written form. It functions as the active verb form associated with the noun deponent (one who depones) and the process of deposition.
The term appears narrowly in historical Anglo-American legal sources and is confined almost entirely to Scottish legal practice and older common law contexts. In modern usage, the act it describes — giving sworn written testimony — is handled by depose, testify, or swear, depending on jurisdiction and procedure.
Common Language
Modern common usage (Wiktionary): To testify, especially in the form of a deposition; to take the deposition of someone; also (archaic) to lay down or wager.
Historical common usage (Webster's 1913): To assert under oath; to depose. Flagged explicitly as a Scotticism. Also carried obsolete senses of "to lay as a stake" and "to lay down."
The gap matters: In ordinary English, Webster's already treats depone as a near-synonym for depose or testify. In legal usage, however, the term carries a more specific procedural implication — sworn written testimony within the Scots law tradition — rather than the broader oral or written testimony the common usage suggests. A researcher encountering depone in a historical English-language source should consider whether it reflects genuine Scots legal influence or informal adoption of the Scotticism into general testimony language.
Common Confusion
DEPONE / DEPOSE: These terms overlap almost entirely in function, and historical sources often use them interchangeably. The distinction, where one exists, is largely jurisdictional: depone is the preferred form in Scots law; depose is the standard term in English and American law. A witness who depones in a Scottish proceeding performs the same essential act as one who deposes in an English court. Researchers should not read substantive procedural differences into the word choice unless the source context makes one explicit.
Why It Matters in Research
Depone is a marker term. Its appearance in a source signals either Scots law influence or a historical period (roughly pre-nineteenth century) when Scottish legal vocabulary was more freely absorbed into English legal writing. Researchers working in early modern British legal records, ecclesiastical court materials, or cross-border commercial disputes between England and Scotland are most likely to encounter it.
The term rarely appears in American legal sources, and when it does, treat it as archaic or as a quotation from a Scottish or English authority rather than as operative American legal vocabulary. Modern American practice uses depose exclusively.
One research trap: because Webster's 1913 labels depone a Scotticism and gives an example from the State Trials (1606), a researcher may encounter the term in English legal proceedings from this period without any direct connection to Scottish courts. The Scotticism had some circulation in early modern English legal writing before falling out of use entirely south of the border.
Corpus connections: Entries for DEPONENT, DEPOSITION, and AFFIDAVIT will capture the procedural framework that depone fits within. If a source uses depone, the surrounding procedural context — whether it describes in-court testimony, pre-trial examination, or written affidavit — will determine which of those related terms governs the substance of what is happening.
Historical Dictionary Support
Black's Law Dictionary and Burrill's Law Dictionary are in complete agreement: depone belongs to Scots practice and means to depose or to make oath in writing. Burrill adds the Latin root deponere, which also underlies depose and deponent, reinforcing that the terms share a common ancestor and differ primarily by legal tradition rather than by meaning.
Neither source elaborates on procedure, and neither addresses how the term was used in English (non-Scottish) courts. Webster's 1913 is actually more informative on the English reception of the term, flagging it as a Scotticism and providing the 1606 State Trials citation as evidence of its appearance in English legal language. That citation is useful precisely because it shows the term crossing jurisdictional lines early.
What historical dictionaries miss: No source addresses the decline of depone in British legal writing after the eighteenth century or its complete absence from American legal vocabulary. Researchers should not assume that finding the term in a legal dictionary means it was widely used in practice — its appearance in Black's and Burrill's likely reflects antiquarian completeness rather than active circulation.
Jurisdictional Note
Depone is operative Scots law terminology and appears in Scottish legal practice. In English and American law, it is archaic and has no procedural standing independent of depose. Researchers working in Scottish court records, including those digitized in British archive collections, will find depone in its natural procedural habitat.
