Okla. Stat. tit. 12, § 3230
A. WHEN DEPOSITIONS MAY BE TAKEN.
1. After commencement of the action, any party may take the testimony of any person, including a party, by deposition upon oral examination. Leave of court, granted with or without notice, shall be obtained only if the plaintiff seeks to take a deposition prior to the expiration of thirty (30) days after service of the summons and petition upon any defendant provided that leave is not required:
B. PLACE WHERE WITNESS OR PARTY IS REQUIRED TO ATTEND TAKING OF DEPOSITIONS.
C. NOTICE OF EXAMINATION; GENERAL REQUIREMENTS; SPECIAL NOTICE; NONSTENOGRAPHIC RECORDING; PRODUCTION OF DOCUMENTS AND THINGS; DEPOSITION OF ORGANIZATION; DEPOSITION BY TELEPHONE.
1. A party desiring to take the deposition of any person upon oral examination shall give notice in writing to every other party to the action. The notice shall state the time and place for taking the deposition and shall state the name and address of each person to be examined, if known, and, if the name is not known, a general description sufficient to identify him or the particular class or group to which he belongs. The notice shall be served in order to allow the adverse party sufficient time, by the usual route of travel, to attend, and three (3) days for preparation, exclusive of the day of service of the notice.
If a subpoena duces tecum is to be served on the person to be examined, the designation of the materials to be produced, as set forth in the subpoena, shall be attached to or included in the notice.
2. Leave of court is not required for the taking of a deposition by plaintiff if the notice states that the person to be examined is about to leave the state and will be unavailable for examination, unless his deposition is taken before expiration of the thirty-day period, and sets forth facts to support the statement. The attorney for the plaintiff shall sign the notice, and his signature constitutes a certification by him that to the best of his knowledge, information and belief the statement and supporting facts are true. For a willful violation of this section, an attorney may be subject to appropriate disciplinary action and sanctions under Section 3237 of this title.
If a party shows that when he was served with notice under this paragraph he was unable, through the exercise of diligence, to obtain counsel to represent him at the taking of the deposition, the deposition may not be used against him.
4. The parties may stipulate in writing or the court may upon motion order that the testimony at a deposition be recorded by other than stenographic means. Unless good cause is shown to the contrary, such motions shall be freely granted. The stipulation or order shall designate the person before whom the deposition shall be taken, the manner of recording, preserving and filing the deposition, and may include other provisions to assure that the recorded testimony will be accurate and trustworthy. If the deposition is recorded by other than stenographic means, the party taking the deposition shall upon request by any party or the witness furnish a copy of the deposition to the witness. The party taking the deposition may furnish either a stenographic copy of the deposition or a copy of the deposition as recorded by other than stenographic means.
Any objections under subsection D of this section, any changes made by the witness, the signature of the witness identifying the deposition as his own or the statement of the officer that is required if the witness does not sign, as provided in subsection F of this section, and the certification of the officer required by subsection G of this section shall be set forth in a writing to accompany a deposition recorded by nonstenographic means.
6. A party may in his notice and in a subpoena name as the deponent a public or private corporation or a partnership or association or governmental agency and describe with reasonable particularity the matters on which examination is requested. In that event, the organization so named shall designate one or more officers, directors or managing agents, or other persons who consent to testify on its behalf, and may set forth, for each person designated, the matters on which he will testify. Such designation of persons to testify and the subject of the testimony shall be delivered to the other party or parties prior to or at the commencement of the taking of the deposition of the organization. A subpoena shall advise a nonparty organization of its duty to make such a designation. The persons so designated shall testify as to matters known or reasonably available to the organization.
This paragraph does not preclude taking a deposition by any other procedure authorized in the Oklahoma Discovery Code.
D. EXAMINATION AND CROSS-EXAMINATION; RECORD OF EXAMINATION; OATH; OBJECTIONS. Examination and cross-examination of witnesses may proceed as permitted at the trial under the provisions of Section 2101 et seq. of this title except Section 2104. The officer before whom the deposition is to be taken shall put the witness on oath or affirmation and shall personally, or by someone acting under his direction and in his presence, record the testimony of the witness. The testimony shall be taken stenographically or recorded by any other method authorized by paragraph 4 of subsection C of this section.
All objections made at the time of the examination to the qualifications of the officer taking the deposition, to the manner of taking it, to the evidence presented, to the conduct of any party, or to any other aspect of the proceedings shall be noted by the officer upon the record of the deposition; however, the examination shall proceed, with the testimony being taken subject to the objections.
In lieu of participating in the oral examination, parties may serve written questions in a sealed envelope on the party taking the depositions and he shall transmit them to the officer, who shall propound them to the witness and record the answers verbatim.
E. MOTION TO TERMINATE OR LIMIT EXAMINATION.
G. CERTIFICATION AND FILING BY OFFICER; EXHIBITS; COPIES; NOTICE OF FILING.
1. The officer shall certify on any stenographic deposition:
d. that the officer is not a relative or employee or attorney or counsel of any of the parties, or a relative or employee of such attorney or counsel, and is not financially interested in the action.
Except on order of the court or unless a deposition is attached to a motion response thereto, is needed for use in a trial or hearing, or the parties stipulate otherwise, depositions shall not be filed with the court clerk. The officer shall securely seal any stenographic deposition in an envelope endorsed with the title of the action and marked "Deposition of (here insert name of witness)" and send it to the attorney who arranged for the deposition, who shall store it under conditions that will protect it against loss, destruction, tampering, or deterioration.
Documents and things produced for inspection during the examination of the witness shall, upon the request of a party, be marked for identification and annexed to the deposition and may be inspected and copied by any party. If the person producing the materials desires to retain them he may:
