While Anil has been summoned on August 22, Tina has been asked to appear before the court on August 23.
Special CBI judge OP Saini has taken on record the list of witnesses to be called for recording evidence submitted by the agency and issued fresh summons to them.
The court had on July 19 allowed CBIs plea to make Anil and Tina Ambani prosecution witnesses in the case.
The court issued the summons to the couple after Ambani, who was scheduled to depose before it on July 26, had sought exemption from personal appearance on the ground that he has pre-scheduled business engagements.
He had said he would appear before the court any day after August 15.
