Rule 57.01 – Interrogatories to Parties [Effective until August 2, 2021]

May 13, 2021 | Civil Procedure, Missouri

(a) Scope. Any party may serve upon any other party written interrogatories. Interrogatories may relate to any matter that can be inquired into under Rule 56.01. An interrogatory otherwise proper is not necessarily objectionable merely because an answer to the interrogatory involves an opinion or contention that relates to fact or the application of law to fact, but the court may order that such an interrogatory need not be answered until after designated discovery has been completed or until a pretrial conference or other later time.
(b) Issuance.

(1) Form. Interrogatories shall be in consecutively numbered paragraphs. The title shall identify the party to whom they are directed and state the number of the set of interrogatories directed to that party.
(2) When Interrogatories May be Served. Without leave of court, interrogatories may be served on:

(A) A plaintiff after commencement of the action, and
(B) Any other party with or after the party was served with process, entered an appearance, or filed a pleading.
(3) Service. Copies of the interrogatories shall be served on all parties not in default. The party issuing the interrogatories shall also provide each answering party an electronic copy, in a commonly used medium such as a diskette, CD-ROM or as an e-mail attachment, in a format that can be read by most commonly used word processing programs, such as Word for Windows or WordPerfect 5.x or higher. In addition to the information normally in a certificate of service, the certificate of service shall also state:

(A) The name of each party who is to respond to the interrogatories;
(B) The number of the set of interrogatories,
(C) The format of the electronic copy and the medium used to transmit the electronic copy to the responding party.

At the time of service, a certificate of service, but not the interrogatories, shall be filed with the court as provided in Rule 57.01(d).

(c) Response. The interrogatories shall be answered by each party to whom they are directed. If they are directed to a public or private corporation, limited liability company, partnership, association or governmental agency, they shall be answered by an officer or agent. The party answering the interrogatories shall furnish such information as is available to the party.

(1) When the Response is Due. Responses shall be served within 30 days after the service of the interrogatories. A defendant, however, shall not be required to respond to interrogatories before the expiration of 45 days after the earlier of:

(A) The date the defendant enters an appearance, or
(B) The date the defendant is served with process.

The court may allow a shorter or longer time.

(2) Form. The title of the response shall identify the responding party and the number of the set of interrogatories. The response to the interrogatories shall quote each interrogatory, including its original paragraph number, and immediately thereunder state the answer or all reasons for not completely answering the interrogatory, including privileges, the work product doctrine and objections.
(3) Objections and Privileges. If information is withheld because of an objection, then each reason for the objection shall be stated. If a privilege or the work product doctrine is asserted as a reason for withholding information, then without revealing the protected information, the objecting party shall state information that will permit others to assess the applicability of the privilege or work product doctrine.
(4) Option to Produce Business Records. If the answer to an interrogatory may be derived or ascertained from:

(A) The business records of the party upon whom the interrogatory has been served, or
(B) An examination, audit or inspection of such business records, or
(C) A compilation, abstract or summary based thereon,

and the burden of deriving or ascertaining the answer is substantially the same for the party serving the interrogatory as for the party served, it is a sufficient answer to such interrogatory to specify the records from which the answer may be derived or ascertained and to afford to the party serving the interrogatory reasonable opportunity to examine, audit or inspect such records and to make copies, compilations, abstracts or summaries.

(5) Signing. Answers shall be signed under oath by the person making them. Objections shall be signed by the attorney making them or by the self-represented party.
(6) Service. The party to whom the interrogatories were directed shall serve a signed original of the answers and objections, if any, on the party that issued the interrogatories and a copy on all parties not in default. The certificate of service shall state the name of the party who issued the interrogatories and the number of the set of interrogatories.

At the time of service, a certificate of service, but not the response, shall be filed with the court as provided in Rule 57.01(d).

(d) Filing. Interrogatories and answers under this Rule 57.01 shall not be filed with the court except upon court order or contemporaneously with a motion placing the interrogatories in issue. However, both when the interrogatories and answers are served, the party serving them shall file with the court a certificate of service.

The certificate shall show the caption of the case, the name of the party served, the date and manner of service, the designation of the document, e.g., first interrogatories or answers to second interrogatories, and the signature of the serving party or attorney. The answers bearing the original signature of the party answering the interrogatories shall be served on the party submitting the interrogatories, who shall be the custodian thereof until the entire case is finally disposed.

Copies of interrogatory answers may be used in all court proceedings to the same extent the original answers may be used.

(e) Enforcement. The party submitting the interrogatory may move for an order under Rule 61.01(b) with respect to any objection to or other failure to answer an interrogatory.
(f) Use at Trial. Interrogatory answers may be used to the extent permitted by the rules of evidence.
