C.R.C.P. 26. — General Provisions Governing Discovery; Duty of Disclosure

(a) Required Disclosures. Unless otherwise ordered by the court or stipulated by the parties, provisions of this Rule shall not apply to domestic relations, juvenile, mental health, probate, water court proceedings subject to sections 37-92-302 to 37-92-305, C.R.S., forcible entry and detainer, C.R.C.P. 120, or other expedited proceedings. (1) Disclosures. Except to the extent otherwise directed by the court, a party shall, without awaiting a discovery request, provide to other parties the following information, whether or not supportive of the disclosing party's claims or defenses: (A) the name and, if known, the address and telephone number of each individual likely to have discoverable information relevant to the claims and defenses of any party and a brief description of the specific information that each such individual is known or believed to possess; (B) a listing, together with a copy of, or a description by category, of the subject matter and location of all documents, data compilations, and tangible things in the possession, custody or control of the party that are relevant to the claims and defenses of any party, making available for inspection and copying such documents and other evidentiary material, not privileged or protected from disclosure, as though a request for production of those documents had been served pursuant to C.R.C.P. 34; (C) a description of the categories of damages sought and a computation of any category of economic damages claimed by the disclosing party, making available for inspection and copying pursuant to C.R.C.P. 34 the documents or other evidentiary material relevant to the damages sought, not privileged or protected from disclosure, as though a request for production of those documents had been served pursuant to C.R.C.P. 34; and (D) any insurance agreement under which any person carrying on an insurance business may be liable to satisfy part or all of a judgment which may be entered in the action or to indemnify or reimburse for payments made to satisfy the judgment, making such agreement available for inspection and copying pursuant to C.R.C.P. 34. Disclosures shall be served within 28 days after the case is at issue as defined in C.R.C.P. 16(b)(1). A party shall make the required disclosures based on the information then known and reasonably available to the party and is not excused from making such disclosures because the party has not completed investigation of the case or because the party challenges the sufficiency of another party's disclosure or because another party has not made the required disclosures. Parties shall make these disclosures in good faith and may not object to the adequacy of the disclosures until the case management conference pursuant to C.R.C.P. 16(d). (2) Disclosure of Expert Testimony. (A) In addition to the disclosures required by subsection (a)(1) of this Rule, a party shall disclose to other parties the identity of any person who may present evidence at trial, pursuant to Rules 702, 703, or 705 of the Colorado Rules of Evidence together with an identification of the person's fields of expertise. (B) Except as otherwise stipulated or directed by the court: (I) Retained Experts. With respect to a witness who is retained or specially employed to provide expert testimony, or whose duties as an employee of the party regularly involve

giving expert testimony, the disclosure shall be made by a written report signed by the witness. The report shall include: (a) a complete statement of all opinions to be expressed and the basis and reasons therefor; (b) a list of the data or other information considered by the witness in forming the opinions; (c) references to literature that may be used during the witness's testimony; (d) copies of any exhibits to be used as a summary of or support for the opinions; (e) the qualifications of the witness, including a list of all publications authored by the witness within the preceding ten years; (f) the fee agreement or schedule for the study, preparation and testimony; (g) an itemization of the fees incurred and the time spent on the case, which shall be supplemented 14 days prior to the first day of trial; and (h) a listing of any other cases in which the witness has testified as an expert at trial or by deposition within the preceding four years. The witness's direct testimony shall be limited to matters disclosed in detail in the report. (II) Other Experts. With respect to a party or witness who may be called to provide expert testimony but is not retained or specially employed within the description contained in subsection (a)(2)(B)(I) above, the disclosure shall be made by a written report or statement that shall include: (a) a complete description of all opinions to be expressed and the basis and reasons therefor; (b) a list of the qualifications of the witness; and (c) copies of any exhibits to be used as a summary of or support for the opinions. If the report has been prepared by the witness, it shall be signed by the witness. If the witness does not prepare a written report, the party's lawyer or the party, if self-represented, may prepare a statement and shall sign it. The witness's direct testimony expressing an expert opinion shall be limited to matters disclosed in detail in the report or statement. (C) Unless otherwise provided in the Case Management Order, the timing of the disclosures shall be as follows: (I) The disclosure by a claiming party under a complaint, counterclaim, cross-claim, or third-party claim shall be made at least 126 days (18 weeks) before the trial date. (II) The disclosure by a defending party shall be made within 28 days after service of the claiming party's disclosure, provided, however, that if the claiming party serves its disclosure earlier than required under subparagraph 26(a)(2)(C)(I), the defending party is not required to serve its disclosures until 98 days (14 weeks) before the trial date. (III) If the evidence is intended to contradict or rebut evidence on the same subject matter identified by another party under subparagraph (a)(2)(C)(II) of this Rule, such disclosure shall be made no later than 77 days (11 weeks) before the trial date. (3) [There is no Colorado Rule-see instead C.R.C.P. 16(c).] (4) Form of Disclosures; Filing. All disclosures pursuant to subparagraphs (a)(1) and (a)(2) of this Rule shall be made in writing, in a form pursuant to C.R.C.P. 10, signed pursuant to C.R.C.P. 26(g)(1), and served upon all other parties. Disclosures shall not be filed with the court unless requested by the court or necessary for consideration of a particular issue. (5) Methods to Discover Additional Matters. Parties may obtain discovery by one or more of the following methods: depositions upon oral examination or written questions; written interrogatories; production of documents or things or permission to enter upon land or other property, pursuant to C.R.C.P. 34; physical and mental examinations; and requests for admission. Discovery at a place within a country having a treaty with the United States applicable to the discovery must be conducted by methods authorized by the treaty except that, if the court determines that those methods are inadequate or inequitable, it may authorize other discovery methods not prohibited by the treaty. (b) Discovery Scope and Limits. Unless otherwise modified by order of the court in accordance with these rules, the scope of discovery is as follows:

(1) In General. Subject to the limitations and considerations contained in subsection (b)(2) of this Rule, parties may obtain discovery regarding any matter, not privileged, that is relevant to the claim or defense of any party and proportional to the needs of the case, considering the importance of the issues at stake in the action, the amount in controversy, the parties' relative access to relevant information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit. Information within the scope of discovery need not be admissible in evidence to be discoverable. (2) Limitations. Except upon order for good cause shown and subject to the proportionality factors in subsection (b)(1) of this Rule, discovery shall be limited as follows: (A) A party may take one deposition of each adverse party and of two other persons, exclusive of persons expected to give expert testimony disclosed pursuant to subsection 26(a)(2). The scope and manner of proceeding by way of deposition and the use thereof shall otherwise be governed by C.R.C.P. 26, 28, 29, 30, 31, 32, and 45. (B) A party may serve on each adverse party 30 written interrogatories, each of which shall consist of a single question. The scope and manner of proceeding by means of written interrogatories and the use thereof shall otherwise be governed by C.R.C.P. 26 and 33. (C) A party may obtain a physical or mental examination (including blood group) of a party or of a person in the custody or under the legal control of a party pursuant to C.R.C.P. 35. (D) A party may serve each adverse party requests for production of documents or tangible things or for entry, inspection or testing of land or property pursuant to C.R.C.P. 34, except such requests for production shall be limited to 20 in number, each of which shall consist of a single request. (E) A party may serve on each adverse party 20 requests for admission, each of which shall consist of a single request. A party may also serve requests for admission of the genuineness of up to 50 separate documents that the party intends to offer into evidence at trial. The scope and manner of proceeding by means of requests for admission and the use thereof shall otherwise be governed by C.R.C.P. 36. (F) In determining good cause to modify the limitations of this subsection (b)(2), the court shall consider the following: (I) whether the discovery sought is unreasonably cumulative or duplicative, or is obtainable from some other source that is more convenient, less burdensome, or less expensive; (II) whether the party seeking discovery has had ample opportunity by disclosure or discovery in the action to obtain the information sought; (III) whether the proposed discovery is outside the scope permitted by C.R.C.P. 26(b)(1); and (IV) whether because of the number of parties and their alignment with respect to the underlying claims and defenses, the proposed discovery is reasonable. (3) Trial Preparation: Materials. Subject to the provisions of subsection (b)(4) of this Rule, a party may obtain discovery of documents and tangible things otherwise discoverable under subsection (b)(1) of this Rule and prepared in anticipation of litigation or for trial by or for another party or by or for that other party's representative (including the party's attorney, consultant, surety, indemnitor, insurer, or agent) only upon a showing that the party seeking discovery has substantial need of the materials in the preparation of the case and is unable without undue hardship to obtain the substantial equivalent of the materials by other means. In ordering discovery of such materials when the required showing has been made, the court shall protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney or other representative of a party concerning the litigation. A party may obtain without the required showing a statement concerning the action or its subject matter previously made by that party. Upon request, a person not a party may obtain without the required showing a statement concerning the action or its subject matter previously made by that person. If the request is refused, the person may move for a court order. The provisions of C.R.C.P. 37(a)(4) apply to the award of expenses incurred in relation to the motion. For purposes of this paragraph, a statement previously made is:

(A) a written statement signed or otherwise adopted or approved by the person making it, or (B) a stenographic, mechanical, electrical, or other recording, or a transcription thereof, which is a substantially verbatim recital of an oral statement by the person making it and contemporaneously recorded. (4) Trial Preparation: Experts. (A) A party may depose any person who has been identified as an expert disclosed pursuant to subsection 26(a)(2) of this Rule whose opinions may be presented at trial. Each deposition shall not exceed 6 hours. On the application of any party, the court may decrease or increase the time permitted after considering the proportionality criteria in subsection (b)(1) of this Rule. Except to the extent otherwise stipulated by the parties or ordered by the court, no discovery, including depositions, concerning either the identity or the opinion of experts shall be conducted until after the disclosures required by subsection (a)(2) of this Rule. (B) A party may, through interrogatories or by deposition, discover facts known or opinions held by an expert who has been retained or specially employed by another party in anticipation of litigation or preparation for trial, and who is not expected to be called as a witness at trial only as provided by C.R.C.P. 35(b) or upon a showing of exceptional circumstances under which it is impracticable for the party seeking discovery to obtain facts or opinions on the same subject by other means. (C) Unless manifest injustice would result, (i) the court shall require that the party seeking discovery pay the expert a reasonable fee for time spent in responding to discovery under this subsection (b)(4); and (ii) with respect to discovery obtained pursuant to subsection (b)(4)(B) of this Rule, the court shall require the party seeking discovery to pay the other party a fair portion of the fees and expenses reasonably incurred by the latter party in obtaining facts and opinions from the expert. (D) Rule 26(b)(3) protects from disclosure and discovery drafts of any report or disclosure required under Rule 26(a)(2), regardless of the form in which the draft is recorded, and protects communications between the party's attorney and any witness disclosed under Rule 26(a)(2)(B), regardless of the form of the communications, except to the extent that the communications: (I) relate to the compensation for the expert's study, preparation, or testimony; (II) identify facts or data that the party's attorney provided and which the expert considered in forming the opinions to be expressed; or (III) identify the assumptions that the party's attorney provided and that the expert relied on in forming opinions to be expressed. (5)(A) Claims of Privilege or Protection of Trial Preparation Materials. When a party withholds information required to be disclosed or provided in discovery by claiming that it is privileged or subject to protection as trial preparation material, the party shall make the claim expressly and shall describe the nature of the documents, communications, or things not produced or disclosed in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the applicability of the privilege or protection. (B) If information produced in disclosures or discovery is subject to a claim of privilege or of protection as trial-preparation material the party making the claim may notify any party that received the information of the claim and the basis for it. After being notified, a party must not review, use or disclose the information until the claim is resolved; must take reasonable steps to retrieve the information if the party disclosed it before being notified; and shall give notice to the party making the claim within 14 days if it contests the claim. If the claim is not contested within the 14-day period, or is timely contested but resolved in favor of the party claiming privilege or protection of trialpreparation material, then the receiving party must also promptly return, sequester, or destroy the specified information and any copies that the receiving party has. If the claim is contested, the party making the claim shall present the information to the court under seal for a determination of the claim within 14 days after receiving such notice, or the claim is waived. The producing party must preserve the information until the claim is

resolved, and bears the burden of proving the basis of the claim and that the claim was not waived. All notices under this Rule shall be in writing. (c) Protective Orders. Upon motion by a party or by the person from whom disclosure is due or discovery is sought, accompanied by a certificate that the movant has in good faith conferred or attempted to confer with other affected parties in an effort to resolve the dispute without court action, and for good cause shown, the court may make any order which justice requires to protect a party or person from annoyance, embarrassment, oppression, or undue burden or expense, including one or more of the following: (1) that the disclosure or discovery not be had; (2) that the disclosure or discovery may be had only on specified terms and conditions, including a designation of the time or place or the allocation of expenses; (3) that the discovery may be had only by a method of discovery other than that selected by the party seeking discovery; (4) that certain matters not be inquired into, or that the scope of the disclosure or discovery be limited to certain matters; (5) that discovery be conducted with no one present except persons designated by the court; (6) that a deposition, after being sealed, be opened only by order of the court; (7) that a trade secret or other confidential research, development, or commercial information not be revealed or be revealed only in a designated way; and (8) that the parties simultaneously file specified documents or information enclosed in sealed envelopes to be opened as directed by the court. (d) Timing and Sequence of Discovery. Except when authorized by these Rules, by order, or by agreement of the parties, a party may not seek discovery from any source before service of the Case Management Order pursuant to C.R.C.P. 16(b)(18). Any discovery conducted prior to issuance of the Case Management Order shall not exceed the limitations established by C.R.C.P. 26(b)(2). Unless the parties stipulate or the court upon motion, for the convenience of parties and witnesses and in the interests of justice, orders otherwise, methods of discovery may be used in any sequence, and the fact that a party is conducting discovery, whether by deposition or otherwise, shall not operate to delay any other party's discovery. (e) Supplementation of Disclosures, Responses, and Expert Reports and Statements. A party is under a duty to supplement its disclosures under section (a) of this Rule when the party learns that the information disclosed is incomplete or incorrect in some material respect and if the additional or corrective information has not otherwise been made known to the other parties during the disclosure or discovery process, including information relating to anticipated rebuttal but not including information to be used solely for impeachment of a witness. A party is under a duty to amend a prior response to an interrogatory, request for production or request for admission when the party learns that the prior response is incomplete or incorrect in some material respect and if the additional or corrective information has not otherwise been made known to the other parties during the discovery process. With respect to experts, the duty to supplement or correct extends both to information contained in the expert's report or statement disclosed pursuant to section (a)(2)(B) of this Rule and to information provided through any deposition of the expert. If a party intends to offer expert testimony on direct examination that has not been disclosed pursuant to section (a)(2)(B) of this Rule on the basis that the expert provided the information through a deposition, the report or statement previously provided shall be supplemented to include a specific description of the deposition testimony relied on. Nothing in this section requires the court to permit an expert to testify as to opinions other than those disclosed in detail in the initial expert report or statement except that if the opinions and bases and reasons therefor are disclosed during the deposition of the expert by the adverse party, the court must permit the testimony at trial unless the court finds that the opposing party has been unfairly prejudiced by the failure to make disclosure in the initial expert report. Supplementation shall be performed in a timely manner. (f) [No Colorado Rule - See C.R.C.P. 16.]

(g) Signing of Disclosures, Discovery Requests, Responses, and Objections. (1) Every disclosure made pursuant to subsections (a)(1) or (a)(2) of this Rule shall be signed by at least one attorney of record in the attorney's individual name. An unrepresented party shall sign the disclosure and state the party's address. The signature of the attorney or party constitutes a certification that to the best of the signer's knowledge, information, and belief, formed after a reasonable inquiry, the disclosure is complete and correct as of the time it is made. (2) Every discovery request, or response, or objection made by a party represented by an attorney shall be signed by at least one attorney of record in the attorney's individual name. An unrepresented party shall sign the request, response, or objection and state the party's address. The signature of the attorney or party constitutes a certification that to the best of the signer's knowledge, information and belief, formed after a reasonable inquiry, the request, response or objection is: (A) Consistent with these rules and warranted by existing law or a good faith argument for the extension, modification, or reversal of existing law; (B) Not interposed for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation; and (C) Not unreasonable or unduly burdensome or expensive, given the needs of the case, the discovery already had in the case, the amount in controversy, and the importance of the issues at stake in the litigation. If a request, response or objection is not signed, it shall be stricken unless it is signed promptly after the omission is called to the attention of the party making the request, response or objection, and a party shall not be obligated to take any action with respect to it until it is signed. (3) If without substantial justification a certification is made in violation of this rule, the court, upon motion or upon its own initiative, may impose upon the person who made the certification, the party on whose behalf the disclosure, request, response or objection is made, or both, an appropriate sanction, which may include an order to pay the amount of the reasonable expenses incurred because of the violation, including reasonable attorney fees.
