Okla. Stat. tit. 12, § 12-2615: Exclusion of witnesses

At the request of a party the court shall order witnesses

excluded so that they cannot hear the testimony of other witnesses.

The court may make the order of its own motion. This rule does not

authorize exclusion of:

1. A party who is a natural person;

2. An officer or employee of a party which is not a natural

person designated as its representative by its attorney;

3. A person whose presence is shown by a party to be essential

to the presentation of the party's cause;

4. A parent, other relative, or next friend of a child as

defined by Section 1-1-105 of Title 10A of the Oklahoma Statutes who

is called to testify when the court deems it to be in the best

interests of the child and the interests of justice; or

5. The victim of an alleged criminal offense or a

representative, parent or other relative of said victim, in any

criminal prosecution, upon the motion of the state to bar such

exclusion, unless the court finds such exclusion to be in the

interest of justice.
