“Southern Charm” star Patricia Altschul has been ordered to sit and be grilled under oath by Thomas Ravenel as part of his nasty custody battle with Kathryn Dennis.

According to court documents obtained by The Blast, a South Carolina judge has sided with Ravenel and denied Altschul’s motion to avoid being dragged into the case.

The judge ordered her to be deposed and it will “last no longer than six hours.” Ravenel and Altschul have to agree on the date.

She was also ordered to turn over all text and email communications between herself and Kathryn Dennis and Luzanne Otte, Ravenel's former girlfriend from April 1, 2018 until now.

Ravenel believes Altschul has information about Dennis colluding with another woman to accuse him of sexual assault. He will now be able to grill his former co-star all about his claims.
