1. PRELIMINARY STATEMENT & AUTHORITY
Pursuant to Missouri Supreme Court Rule 57.01, [PROPOUNDING PARTY] serves these interrogatories on [RESPONDING PARTY]. Responses ordinarily must be served within 30 days after service. A defendant is not required to respond before 45 days after the earlier of the defendant’s appearance or service of process. The court may allow a shorter or longer time. Mo. Sup. Ct. R. 57.01(c)(1).
Unless the parties stipulate otherwise, the court orders otherwise, or an approved local rule applies under Rule 56.01(b)(8), this set may contain no more than 25 interrogatories, including all discrete subparts. Mo. Sup. Ct. R. 57.01(a). Count every discrete subpart after final editing and delete any question that is not relevant and proportional to the needs of this case.
2. DEFINITIONS
For purposes of these Interrogatories, the following definitions apply:
A. “You,” “Your,” or “Responding Party” means [RESPONDING PARTY NAME]. If the Responding Party is an entity, the responses must be made through an officer or agent and must furnish information available to the party. Mo. Sup. Ct. R. 57.01(c). This definition does not enlarge the scope of discovery or require disclosure of privileged matter.
B. “Document” and “Documents” include writings, electronically stored information (“ESI”), photographs, recordings, and tangible things within the scope of Mo. Sup. Ct. R. 56.01(b)(1).
C. “Communication” means any transmission of information, whether oral, written, electronic, or otherwise.
D. “Identify” when referring to a person means to provide the person’s full name, last known address, telephone number, employer, and job title. When referring to a document, “identify” means to provide (i) the type of document, (ii) its date, (iii) author(s) and recipient(s), (iv) general subject matter, and (v) present custodian or location.
E. “Incident” refers to the event or events giving rise to the claims or defenses in this Action, as further described in the pleadings.
F. “Action” means the above-captioned lawsuit.
3. GENERAL INSTRUCTIONS
-
Response Form
Quote each interrogatory, including its original paragraph number, and immediately below it state the answer or every reason for not completely answering. Answers must be signed under oath by the person making them; objections must be signed by the attorney making them or by the self-represented party. Mo. Sup. Ct. R. 57.01(c)(2), (5). -
Duty to Amend
Seasonably amend a response if You learn that it is materially incomplete or incorrect and the additional or corrective information has not otherwise been made known during discovery or in writing. Mo. Sup. Ct. R. 56.01(e). -
Objections
If information is withheld because of an objection, state each reason for the objection. If an interrogatory is not completely answered, identify all reasons for the incomplete answer. Mo. Sup. Ct. R. 57.01(c)(2)-(3). -
Privilege and Work Product
If privilege or the work-product doctrine is asserted, state information that permits others to assess the asserted protection without revealing the protected information. Mo. Sup. Ct. R. 57.01(c)(2)-(3). -
Scope and ESI
These interrogatories seek only nonprivileged matter within Rule 56.01(b)(1)’s relevance and proportionality limits. Rule 56.01(b)(3) separately addresses ESI sources identified as not reasonably accessible because of undue burden or cost. -
Option to Produce Business Records
If Rule 57.01(c)(4) applies, specify the records from which the answer may be derived or ascertained and afford the requesting party a reasonable opportunity to examine, audit, or inspect the records and make copies, compilations, abstracts, or summaries. -
Time Period
Unless otherwise specified, each Interrogatory seeks information from the earliest date relevant to the Action through the present.

☐ The final set contains no more than 25 interrogatories, including every discrete subpart, unless a stipulation, court order, or approved local rule authorizes otherwise. Mo. Sup. Ct. R. 57.01(a).

Legal authority
- Mo. Sup. Ct. R. 57.01(a)-(d) (interrogatory scope, issuance, response, and filing)
- Mo. Sup. Ct. R. 56.01(b)(1), (3)-(7), and (e) (scope, ESI, insurance, trial-preparation materials, experts, and supplementation)
These are the filings that drive a lawsuit through the system: complaints, answers, motions, briefs, discovery requests and responses, and post-judgment papers. Each has its own format requirements under federal and state procedural rules, and each has a deadline that cannot be missed without consequences. Clean, procedurally correct filings move a case forward; sloppy ones invite motions to strike, amended responses, and avoidable delays.
