Okla. Stat. tit. 12, § 12-3229: Stipulations regarding discovery procedure

Unless the court orders otherwise, the parties may by written

stipulation:

1. Provide that depositions may be taken before any person, at

any time or place, upon any notice, and in any manner and when so

taken may be used like other depositions; and

2. Modify other procedures governing or limitations placed upon

discovery, except that stipulations extending the time provided in

Sections 3226, 3233, 3234 and 3236 of this title for responses to

discovery may, if they would interfere with any time set for

completion of discovery, be made only with the approval of the

court. A person designated by the stipulation has the power by

virtue of his designation to administer any necessary oath.
