'Southern Charm' Star Thomas Ravenel Trying to Force 77-Year-Old Co-Star to Testify in Custody Battle With Kathryn Dennis

"Southern Charm" star Thomas Ravenel is demanding his 77-year-old co-star Patricia Altschul not be allowed to skip out on a deposition in his custody battle with Kathryn Dennis.

According to court documents obtained by The Blast, Ravenel is not interested in Altschul's efforts to not be grilled under oath in the case.

He says Altschul's objections to being deposed because of her gender and her age are without merit, pointing to her "energy to be the star of a reality TV show, she should have the energy to appear for one afternoon of deposition."

Ravenel says Altschul has known both him and Dennis for many years as both a friend and co-star on "Southern Charm." He says Altschul has witnessed them both with their kids and has relevant testimony to give in the case. He believes she may have text conversations that back up his claim Dennis colluded with another woman to accuse him of sexual assault.

Recently, Altschul went to court asking a South Carolina judge not to force her to be deposed by Ravenel in his custody battle with Dennis.

Altschul is a socialite who stars on "Southern Charm" and her son, Whitney Sudler-Smith, executive produces the reality show. She is a close friend of Kathryn Dennis.

Ravenel had fired off a subpoena seeking to question her about Dennis and Bravo, and about his claim they colluded together.

She says she is only “involved” in his matter because she is a character on a TV show. Altschul says she does not want to be involved in this case for either party.

Altschul’s lawyer points out that his client is a female in her seventies “who should not be subjected to hours of questioning regarding issues that are totally irrelevant to this case.”

She said Ravenel’s attempt to depose her is nothing more than harassment.

The judge has yet to rule.
