in effect

Cal. Code of Civil Procedure - CCP § 2030.210. Section 2030.210.

(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). (d) In order to facilitate the discovery process: (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.

Cal. Code of Civil Procedure - CCP § 2030.220. Section 2030.220.

(a) Each answer in a response to interrogatories shall be as complete and straightforward as the information reasonably available to the responding party permits. (b) If an interrogatory cannot be answered completely, it shall be answered to the extent possible. (c) If the responding party does not have personal knowledge sufficient to respond fully to an interrogatory, that party shall so state, but shall make a reasonable and good faith effort to obtain the information by inquiry to other natural persons or organizations, except where the information is equally available to the propounding party.

Cal. Code of Civil Procedure - CCP § 2030.230. Section 2030.230.

If the answer to an interrogatory would necessitate the preparation or the making of a compilation, abstract, audit, or summary of or from the documents of the party to whom the interrogatory is directed, and if the burden or expense of preparing or making it would be substantially the same for the party propounding the interrogatory as for the responding party, it is a sufficient answer to that interrogatory to refer to this section and to specify the writings from which the answer may be derived or ascertained. This specification shall be in sufficient detail to permit the propounding party to locate and to identify, as readily as the responding party can, the documents from which the answer may be ascertained. The responding party shall then afford to the propounding party a reasonable opportunity to examine, audit, or inspect these documents and to make copies, compilations, abstracts, or summaries of them.

Cal. Code of Civil Procedure - CCP § 2030.240. Section 2030.240.

(a) If only a part of an interrogatory is objectionable, the remainder of the interrogatory shall be answered. (b) If an objection is made to an interrogatory or to a part of an interrogatory, the specific ground for the objection shall be set forth clearly in the response. If an objection is based on a claim of privilege, the particular privilege invoked shall be clearly stated. If an objection is based on a claim that the information sought is protected work product under Chapter 4 (commencing with Section 2018.010), that claim shall be expressly asserted.

Cal. Code of Civil Procedure - CCP § 2030.250. Section 2030.250.

(a) The party to whom the interrogatories are directed shall sign the response under oath unless the response contains only objections. (b) If that party is a public or private corporation, or a partnership, association, or governmental agency, one of its officers or agents shall sign the response under oath on behalf of that party. If the officer or agent signing the response on behalf of that party is an attorney acting in that capacity for the party, that party waives any lawyer-client privilege and any protection for work product under Chapter 4 (commencing with Section 2018.010) during any subsequent discovery from that attorney concerning the identity of the sources of the information contained in the response. (c) The attorney for the responding party shall sign any responses that contain an objection.

Cal. Code of Civil Procedure - CCP § 2030.260. Section 2030.260.

(a) Within 30 days after service of interrogatories, the party to whom the interrogatories are propounded shall serve the original of the response to them on the propounding party, unless on motion of the propounding party the court has shortened the time for response, or unless on motion of the responding party the court has extended the time for response. (b) Notwithstanding subdivision (a), in an unlawful detainer action or other proceeding under Chapter 4 (commencing with Section 1159) of Title 3 of Part 3, the party to whom the interrogatories are propounded shall have five days from the date of service to respond, unless on motion of the propounding party the court has shortened the time for response, or unless on motion of the responding party the court has extended the time for response. (c) The party to whom the interrogatories are propounded shall also serve a copy of the response on all other parties who have appeared in the action. On motion, with or without notice, the court may relieve the party from this requirement on its determination that service on all other parties would be unduly expensive or burdensome.

Cal. Code of Civil Procedure - CCP § 2030.270. Section 2030.270.

(a) The party propounding interrogatories and the responding party may agree to extend the time for service of a response to a set of interrogatories, or to particular interrogatories in a set, to a date beyond that provided in Section 2030.260. (b) This agreement may be informal, but it shall be confirmed in a writing that specifies the extended date for service of a response. (c) Unless this agreement expressly states otherwise, it is effective to preserve to the responding party the right to respond to any interrogatory to which the agreement applies in any manner specified in Sections 2030.210, 2030.220, 2030.230, and 2030.240.

Cal. Code of Civil Procedure - CCP § 2030.280. Section 2030.280.

(a) The interrogatories and the response thereto shall not be filed with the court. (b) The propounding party shall retain both the original of the interrogatories, with the original proof of service affixed to them, and the original of the sworn response until six months after final disposition of the action. At that time, both originals may be destroyed, unless the court on motion of any party and for good cause shown orders that the originals be preserved for a longer period.

Cal. Code of Civil Procedure - CCP § 2030.290. Section 2030.290.

If a party to whom interrogatories are directed fails to serve a timely response, the following rules apply: (a) The party to whom the interrogatories are directed waives any right to exercise the option to produce writings under Section 2030.230, as well as any objection to the interrogatories, including one based on privilege or on the protection for work product under Chapter 4 (commencing with Section 2018.010). The court, on motion, may relieve that party from this waiver on its determination that both of the following conditions are satisfied: (1) The party has subsequently served a response that is in substantial compliance with Sections 2030.210, 2030.220, 2030.230, and 2030.240. (2) The party’s failure to serve a timely response was the result of mistake, inadvertence, or excusable neglect. (b) The party propounding the interrogatories may move for an order compelling response to the interrogatories. (c) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion to compel a response to interrogatories, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust. If a party then fails to obey an order compelling answers, the court may make those orders that are just, including the imposition of an issue sanction, an evidence sanction, or a terminating sanction under Chapter 7 (commencing with Section 2023.010). In lieu of or in addition to that sanction, the court may impose a monetary sanction under Chapter 7 (commencing with Section 2023.010).

Cal. Code of Civil Procedure - CCP § 2030.300. Section 2030.300.

(a) On receipt of a response to interrogatories, the propounding party may move for an order compelling a further response if the propounding party deems that any of the following apply: (1) An answer to a particular interrogatory is evasive or incomplete. (2) An exercise of the option to produce documents under Section 2030.230 is unwarranted or the required specification of those documents is inadequate. (3) An objection to an interrogatory is without merit or too general. (b) (1) A motion under subdivision (a) shall be accompanied by a meet and confer declaration under Section 2016.040. (2) In lieu of a separate statement required under the California Rules of Court, the court may allow the moving party to submit a concise outline of the discovery request and each response in dispute. (c) Unless notice of this motion is given within 45 days of the service of the verified response, or any supplemental verified response, or on or before any specific later date to which the propounding party and the responding party have agreed in writing, the propounding party waives any right to compel a further response to the interrogatories. (d) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion to compel a further response to interrogatories, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust. (e) If a party then fails to obey an order compelling further response to interrogatories, the court may make those orders that are just, including the imposition of an issue sanction, an evidence sanction, or a terminating sanction under Chapter 7 (commencing with Section 2023.010). In lieu of, or in addition to, that sanction, the court may impose a monetary sanction under Chapter 7 (commencing with Section 2023.010).

Cal. Code of Civil Procedure - CCP § 2030.310. Section 2030.310.

(a) Without leave of court, a party may serve an amended answer to any interrogatory that contains information subsequently discovered, inadvertently omitted, or mistakenly stated in the initial interrogatory. At the trial of the action, the propounding party or any other party may use the initial answer under Section 2030.410, and the responding party may then use the amended answer. (b) The party who propounded an interrogatory to which an amended answer has been served may move for an order that the initial answer to that interrogatory be deemed binding on the responding party for the purpose of the pending action. This motion shall be accompanied by a meet and confer declaration under Section 2016.040. (c) The court shall grant a motion under subdivision (b) if it determines that all of the following conditions are satisfied: (1) The initial failure of the responding party to answer the interrogatory correctly has substantially prejudiced the party who propounded the interrogatory. (2) The responding party has failed to show substantial justification for the initial answer to that interrogatory. (3) The prejudice to the propounding party cannot be cured either by a continuance to permit further discovery or by the use of the initial answer under Section 2030.410. (d) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion to deem binding an initial answer to an interrogatory, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust.
