(a) Availability; procedures for use. During standard discovery, any party may serve written interrogatories upon any other party, subject to the limits of Rule 26(c)(5). Each interrogatory shall be separately stated and numbered.
(b) Answers and objections. The responding party shall serve a written response within 28 days after service of the interrogatories. The responding party shall restate each interrogatory before responding to it. Each interrogatory shall be answered separately and fully in writing under oath or affirmation, unless it is objected to. If an interrogatory is objected to, the party shall state the reasons for the objection. Any reason not stated is waived unless excused by the court for good cause. An interrogatory is not objectionable merely because an answer involves an opinion or argument that relates to fact or the application of law to fact. The party shall answer any part of an interrogatory that is not objectionable.
(c) Scope; use at trial. Interrogatories may relate to any discoverable matter. Answers may be used as permitted by the Rules of Evidence.
(d) Option to produce business records. If the answer to an interrogatory may be found by inspecting the answering party’s business records, including electronically stored information, and the burden of finding the answer is substantially the same for both parties, the answering party may identify the records from which the answer may be found. The answering party must give the asking party reasonable opportunity to inspect the records and to make copies, compilations, or summaries. The answering party must identify the records in sufficient detail to permit the asking party to locate and to identify them as readily as the answering party.

Plain-English Summary

Interrogatories are written questions one party sends another to pin down facts before trial. Rule 33 lets any party serve them on any other party during standard discovery, subject to the numeric limits set out in Rule 26(c)(5). Each question has to stand on its own — separately stated and separately numbered — so the responding party can address every one without guessing what's being asked.

The responding party gets 28 days to serve a written response. Before answering, that party must restate the interrogatory, then answer it fully and under oath or affirmation, unless the party objects instead. An objection has to come with reasons; leave a reason out and it's treated as waived unless the court excuses the omission for good cause. Utah courts won't let a party dodge a question just because answering calls for an opinion or requires applying law to fact — that alone isn't a valid objection. And even when part of a question is objectionable, the responding party still has to answer whatever part isn't.

Interrogatories can cover any matter that's otherwise discoverable, and the answers can be used at trial the same way any other evidence is, subject to the Rules of Evidence. Rule 33 also gives the responding party an alternative to writing out a narrative answer: when the answer sits in the party's own business records, including electronic records, and pulling it out would take about the same effort for either side, the responding party can point to those records instead. That shortcut comes with strings attached — the responding party has to give the other side a real chance to inspect the records, make copies or summaries, and has to identify the records specifically enough that the asking party can find the answer just as easily as the responding party could.

Frequently Asked Questions

What is an interrogatory under Utah Rule 33?

It's a written question one party serves on another party during discovery, requiring a written answer under oath or affirmation, or a valid objection, within 28 days.

How long does a party have to answer interrogatories in Utah?

28 days after service of the interrogatories. The responding party must restate each question before answering it.

Can I object to an interrogatory instead of answering it?

Yes, but the objection has to state the reasons. Any reason left out is waived unless the court excuses the omission for good cause, and you still have to answer any part of the interrogatory that isn't objectionable.

Can I refuse to answer an interrogatory because it asks for my opinion?

No. An interrogatory isn't objectionable merely because answering it calls for an opinion or requires applying law to a set of facts.

Do interrogatory answers have to be sworn?

Yes. Each interrogatory must be answered separately and fully in writing, under oath or affirmation, unless it's objected to.

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

Yes, when the answer can be found in your business records, including electronically stored information, and locating it would take about the same effort for either side. You have to give the other party a real opportunity to inspect and copy the records and identify them specifically enough to be found readily.

Are there limits on how many interrogatories a party can serve?

Yes. Rule 33 interrogatories are subject to the numeric limits set out in Rule 26(c)(5).
