The court trying any civil case may upon its own motion, and shall upon the motion of any party, require the exclusion of every witness. However, the following shall be exempt from the rule of this section as a matter of right:
Where expert witnesses are to testify in the case, the court may, at the request of all parties, allow one expert witness for each party to remain in the courtroom; however, in cases pertaining to the distribution of marital property pursuant to § 20-107.3 or the determination of child or spousal support pursuant to § 20-108.1, the court may, upon motion of any party, allow one expert witness for each party to remain in the courtroom throughout the hearing.
