Text sizeJump to: (a) (b) (c) (d)

(a) In General. —
(1) Number. — Unless otherwise stipulated or ordered by the court, a party may serve on any other party no more than 25 written interrogatories, including all discrete subparts. Leave to serve additional interrogatories may be granted to the extent consistent with Rule 26(b)(1) and (2).
(2) Scope. — An interrogatory may relate to any matter that may be inquired into under Rule 26(b). 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) Answers and Objections. —
(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, or a governmental agency, 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. A shorter or longer time may be stipulated to under Rule 29 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 Wyoming 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.

Plain-English Summary

Interrogatories are written questions one party sends another, and Rule 33 sets the ground rules for using them. Absent a stipulation or court order raising the number, a party may serve no more than 25 interrogatories on any other party, counting discrete subparts toward that total, though a party can ask the court for leave to serve more when the case calls for it. The subject matter interrogatories can cover is broad -- anything within the general scope of discovery under Rule 26(b) -- and an interrogatory does not become objectionable just because it asks for an opinion or a contention that touches on the application of law to the facts. The court can, however, hold off requiring an answer to that kind of interrogatory until later in the case, such as after other discovery wraps up or ahead of a pretrial conference, if answering early would not be efficient.

The responding party gets 30 days to serve answers and any objections, though the parties can agree to a different schedule under Rule 29 or the court can set one. Whoever answers has to do so under oath, addressing each interrogatory separately and in full to the extent it is not objected to, and sign the answers personally; the attorney raising an objection signs that objection. Objections must state their grounds with real specificity, and a ground left out of a timely objection is treated as waived unless the court excuses the omission for good cause -- a rule designed to stop a party from sitting on undisclosed objections and raising them for the first time much later. When a corporation, partnership, or other entity is the party being asked, any officer or agent with access to the needed information can answer on its behalf. Rule 33(d) gives a responding party an alternative to answering directly: if the answer can be found by examining the party's business records and the burden of digging it out would be about the same for either side, the responding party can instead point the interrogating party to the specific records and give it a fair chance to examine, copy, or summarize them.

Frequently Asked Questions

How many interrogatories can I send to another party in a Wyoming case?

Rule 33(a)(1) caps the number at 25, including all discrete subparts, unless the parties stipulate to more or the court grants leave to serve additional interrogatories.

How long does the other side have to answer written interrogatories?

Thirty days after being served, under Rule 33(b)(2), unless the parties agree to a different schedule under Rule 29 or the court orders a different time.

Can I object to an interrogatory just because it asks for an opinion or a legal conclusion?

Not on that basis alone. Rule 33(a)(2) says an interrogatory is not objectionable merely because it calls for an opinion or a contention relating to fact or the application of law to fact, though the court can delay when an answer to that kind of interrogatory is due.

What happens if I do not state the specific grounds for an objection to an interrogatory?

Rule 33(b)(4) requires that objection grounds be stated with specificity, and any ground left out of a timely objection is waived unless the court excuses the failure for good cause.

Can I answer an interrogatory by pointing to my business records instead of writing out a full answer?

Yes, under Rule 33(d), if the answer can be derived from examining, compiling, or summarizing business records and the burden of doing so would fall about equally on either party. You must specify the records in enough detail for the other side to locate them and give that party a reasonable chance to examine or copy them.
