'Southern Charm' star Thomas Ravenel has fired off a subpoena to Uber in order to force the ride sharing company to hand over its records amid his custody battle with his ex Kathryn Dennis, which Uber has refused to do, DailyMail.com can disclose.

Ravenel, 56, is demanding that a hearing be set to have Uber explain why it has not complied with subpoenas to produce the documents, according to court papers filed in Charleston on Friday.

The former State Treasurer for South Carolina is duking it out in family court with Dennis, 27, who is the mother of his two children, Kensie, four, and St. Julien, three.

In his subpoena request, Ravenel demands that Uber turn over the records from the accounts attached to either Dennis and/or two phone numbers he had listed from the time period of June 2017 to present. Ostensibly Ravenel is seeking information that could prove neglect on Dennis' part.

Thomas Ravenel fired off a subpoena to Uber in order to force the ride sharing company to hand over its records amid his custody battle with his ex Kathryn Dennis - but Uber is refusing

The former State Treasurer for South Carolina is duking it out in family court with Dennis, 27, who is the mother of his two children, Kensington Calhoun, four, and St. Julien Rembert, three

But Uber wrote a letter to Ravenel explaining the subpoena was 'overbroad' and 'burdensome', and it was objecting to turning over any records to him.

Uber then said the documents could be requested from Dennis.

A judge has yet to rule on the most recent filing.

Ravenel's latest legal move comes days after Dennis alleged that he once threw a party and encouraged guests to take magic mushrooms.

The mother-of-two wants Ravenel to testify under oath about his alleged drug use, according to court documents obtained by The Blast.

She also wants the 56-year-old to produce evidence to support his claims made earlier this month that she has abused drugs.

He has earlier claimed in court documents that she had bought prescription medication from the show's producers and that she abused drugs and alcohol during both of her pregnancies.

But Uber wrote a letter back to Ravenel explaining the subpoena is overbroad and burdensome, objecting to turn over any records to him and said the documents could be requested from Dennis

In retaliation, Dennis asked: 'What date was it when you threw a party in your home downtown with illegal drugs present and you informed fellow party participants while standing in the bathroom that mushrooms don't show up on drug screens?'

She also questions in the court documents whether Ravenel has ever been evaluated for having bipolar disorder and asked him to provide a full list of the women who have accused him of sexual assault or harassment.

In his response, Ravenel asked the court for a protective order and refused to fulfill many of the requests Dennis made.

He said the information that Dennis has requested is only an attempt to 'annoy, embarrass, oppress or create an unburden' for him.

Dennis has previously used sexual assault allegations from two separate women against Ravenel to help bolster her effort to get custody of the children.

She filed court documents in December that raised claims he had paid one of the alleged victims $200,000 for her silence.

Dennis argued in the filing that since their custody agreement was put in place in 2017, 'many new things have come to light'.

Ravenel was arrested in September after former nanny Dawn Ledwell claimed she was in his Charleston home in January 2015 when he allegedly took off her pants and fondled her.

He now awaits trial over those charges. Ledwell also filed a lawsuit against him.

Ravenel was subsequently dropped from the reality show, as well as Bravo and its parent companies.

He was arrested in 2007 less than a year into his term as South Carolina treasurer after he bought cocaine for himself and his friends. The real estate developer pleaded guilty and spent 10 months in prison.

In 2014, Ravenel pleaded guilty to driving under the influence on Long Island, New York, resulting in his license being suspended for six months.
