60-233. Interrogatories to parties. (a) In general. (1) Availability; timing. A party may serve written interrogatories on the plaintiff after commencement of the action and on any other party with or after service of process on that party.
(2) Scope. An interrogatory may relate to any matter that may be inquired into under subsection (b) of K.S.A. 60-226, and amendments thereto. An interrogatory is not objectionable merely because it asks for an opinion or contention that relates to fact or the application of law to fact, but the court may order that the interrogatory need not be answered until designated discovery is complete, or until a pretrial conference or some other time.
(b) Answer and objection. (1) Responding party. The interrogatories must be answered:
(A) By the party to whom they are directed; or
(B) if that party is a public or private corporation, a partnership, an association, a governmental agency or other entity, by any officer or agent, who must furnish the information available to the party.
(2) Time to respond. The responding party must serve its answers and any objections within 30 days after being served with the interrogatories, except that a defendant may serve answers or objections within 45 days after being served with process. A shorter or longer time may be stipulated to under K.S.A. 60-229, and amendments thereto, or be ordered by the court.
(3) Answering each interrogatory. Each interrogatory must, to the extent it is not objected to, be answered separately and fully in writing under oath.
(4) Objections. The grounds for objecting to an interrogatory must be stated with specificity. Any ground not stated in a timely objection is waived unless the court, for good cause, excuses the failure.
(5) Signature. The person who makes the answers must sign them, and the attorney who objects must sign any objections.
(c) Use. An answer to an interrogatory may be used to the extent allowed by the rules of evidence.
(d) Option to produce business records. If the answer to an interrogatory may be determined by examining, auditing, compiling, abstracting or summarizing a party's business records, including electronically stored information, and if the burden of deriving or ascertaining the answer will be substantially the same for either party, the responding party may answer by:
(1) Specifying the records that must be reviewed, in sufficient detail to enable the interrogating party to locate and identify them as readily as the responding party could; and
(2) giving the interrogating party a reasonable opportunity to examine and audit the records and to make copies, compilations, abstracts or summaries.
