Definition
Direct interrogatories are written questions submitted to a witness or deponent by the party who called or designated that witness, as distinguished from cross-interrogatories submitted by the opposing party. They are the written equivalent of direct examination questions posed in live testimony — the first round of questioning, framed by the sponsoring party to elicit testimony favorable to their case.
In practice, direct interrogatories arise specifically in the context of depositions conducted on written questions rather than oral examination. Instead of attorneys appearing in person to question a witness, both sides submit their questions in advance in written form. The sponsoring party's questions are direct interrogatories; the adverse party's responsive questions are cross-interrogatories.

Common Confusion
DIRECT INTERROGATORIES vs. INTERROGATORIES (DISCOVERY): These are distinct procedural devices. Interrogatories in modern discovery practice — governed by rules such as Federal Rule of Civil Procedure 33 — are written questions directed to a party, answered in writing under oath, and used as a standalone discovery tool. Direct interrogatories, by contrast, are written questions posed to a witness as part of a deposition on written questions. Conflating the two is easy in historical sources, where "interrogatories" alone could refer to either context. A researcher encountering "interrogatories" in older materials must determine from context whether a deposition proceeding or party discovery is being described.
DIRECT INTERROGATORIES vs. DIRECT EXAMINATION: Direct interrogatories are the written-question analog to oral direct examination, but they operate within a distinct procedural mechanism — the deposition on written questions — rather than live courtroom testimony. The substantive logic is the same; the procedural form is different.

Why It Matters in Research
This term appears almost exclusively in older procedural materials and historical case law. The deposition on written questions — the procedure in which direct interrogatories live — has become increasingly rare in modern litigation. Under the Federal Rules of Civil Procedure, depositions on written questions (Rule 31) remain available but are seldom used compared to oral depositions. Researchers working with pre-twentieth-century sources will encounter this term frequently, particularly in equity practice and admiralty proceedings where written interrogatories were the dominant mode of taking testimony.
Historical trap: In older equity practice, written interrogatories to witnesses were the norm, not the exception. Sources from chancery or early American equity procedure will use "direct interrogatories" and "cross-interrogatories" in ways that assume this context. Modern readers accustomed to oral depositions may misread these passages as referring to party discovery interrogatories under modern rules — a significant interpretive error.
Jurisdictional variation matters here historically. Different court systems — federal equity, state chancery, admiralty — had varying rules about the form and sequence of written interrogatories, the right to redirect (re-direct interrogatories), and how objections were handled. Researchers should not assume uniform procedure across these tribunals.
The term connects naturally to the broader law of evidence and witness examination. Understanding direct interrogatories requires understanding the structural logic of examination sequences: direct, cross, redirect, recross. That logic is identical whether testimony is taken orally or in writing; the terminology shifts to reflect the written form.

Historical Dictionary Support
Black's Law Dictionary provides a clean and reliable definition: direct interrogatories correspond to direct examination questions and are posed by the calling party, while cross-interrogatories are posed by the adverse party. This entry accurately captures the core distinction and situates the term within deposition practice on written questions.
Black's framing is largely complete for the term's primary meaning. What it does not address is the practical disappearance of this procedural device in modern litigation, nor does it flag the confusion risk with discovery interrogatories — a conflation that became increasingly common as Rule 33-style party interrogatories dominated twentieth-century civil practice and displaced the older written-deposition usage in everyday legal vocabulary.
No meaningful divergence exists across historical dictionary sources on this term; the definition has been consistent because the term's usage was always procedurally specific and technically bounded.

Jurisdictional Note
The deposition on written questions, within which direct interrogatories operate, exists in federal practice under Federal Rule of Civil Procedure 31 and has analogs in most state procedural systems. However, the procedure's practical significance varies dramatically: it remains in occasional use for geographically remote witnesses or in international proceedings, but it is effectively obsolete in routine domestic federal and state litigation.
