Title 4. Civil Discovery Act · Chapter 13. Written Interrogatories · Article 2. Response to Interrogatories · Last amended 2020 · Last verified July 29, 2026
In one sentenceSection 2030.210 requires a party responding to interrogatories to answer, exercise the option to produce writings, or object, separately to each interrogatory and in matching numbered sequence, and sets a process for exchanging both the interrogatories and the responses in electronic format on request, with the responding party including the question text when that format is used.
(a)The party to whom interrogatories have been propounded shall respond in writing under oath separately to each interrogatory by any of the following:
(1)An answer containing the information sought to be discovered.
(2)An exercise of the party's option to produce writings.
(3)An objection to the particular interrogatory.
(b)In the first paragraph of the response immediately below the title of the case, there shall appear the identity of the responding party, the set number, and the identity of the propounding party.
(c)Each answer, exercise of option, or objection in the response shall bear the same identifying number or letter and be in the same sequence as the corresponding interrogatory. The text of that interrogatory need not be repeated, except as provided in paragraph (6) of subdivision (d).
(1)Except as provided in paragraph (5), upon request by the responding party, the propounding party shall provide the interrogatories in an electronic format to the responding party within three court days of the request.
(2)Except as provided in paragraph (5), upon request by the propounding party after receipt of the responses to the interrogatories, the responding party shall provide the responses in an electronic format to the propounding party within three court days of the request.
(3)A party may provide the interrogatories or responses to the interrogatories requested pursuant to paragraphs (1) and (2) in any format agreed upon by the parties. If the parties are unable to agree on a format, the interrogatories or responses to interrogatories shall be provided in plain text format.
(4)A party may transmit the interrogatories or responses to the interrogatories requested pursuant to paragraphs (1) and (2) by any method agreed upon by the parties. If the parties are unable to agree on a method of transmission, the interrogatories or responses to interrogatories shall be transmitted by electronic mail to an email address provided by the requesting party.
(5)If the interrogatories or responses to interrogatories were not created in an electronic format, a party is not required to create the interrogatories or response to interrogatories in an electronic format for the purpose of transmission to the requesting party.
(6)A responding party who has requested and received the interrogatories in an electronic format pursuant to paragraph (1) shall include the text of the interrogatory immediately preceding the response.
Plain-English Summary
This section supplies the basic architecture every response to interrogatories has to follow. Each interrogatory gets its own separate response, and that response can only take one of three forms: an answer supplying the information sought, an exercise of the option under Section 2030.230 to point to underlying business records instead of writing out an answer, or an objection to that particular interrogatory. The response's caption has to identify the responding and propounding parties and the set number, and each answer, option, or objection must carry the same number or letter as its corresponding interrogatory, in the same order, though the interrogatory's own text does not have to be repeated unless the electronic-exchange rule below applies.
Subdivision (d) modernizes the exchange process for parties who want it. On request, the propounding party must supply the interrogatories themselves in electronic format within three court days, and the responding party must reciprocate with the responses in electronic format within three court days of a request made after the responses are served. The parties can agree on whatever file format and transmission method they like; absent agreement, the fallback is plain text sent by email to an address the requesting party supplies. A party need not create an electronic version of something that never existed in that format. And a responding party who receives the interrogatories electronically under this process has to include the actual interrogatory text immediately before its answer, so the electronic response reads as a self-contained document.
Frequently Asked Questions
What are the three permitted forms of response to a single interrogatory?
An answer providing the information sought, an exercise of the option to produce writings under Section 2030.230, or an objection to that interrogatory.
Must each response be numbered the same way as the interrogatory it answers?
Yes. Each answer, exercise of option, or objection must carry the same identifying number or letter, in the same sequence, as its corresponding interrogatory.
Can a party request the interrogatories or responses in electronic format?
Yes. On request, the propounding party must provide the interrogatories electronically within three court days, and the responding party must provide its responses electronically within three court days of a post-response request.
What format applies if the parties cannot agree on one for electronic exchange?
Plain text format, transmitted by email to an address the requesting party provides, if the parties cannot agree on a method.
Does a party have to create an electronic version of interrogatories or responses that were never in that format?
No. Subdivision (d)(5) excuses a party from creating an electronic format for something not originally created that way.
