Kathryn Dennis has responded to ex Thomas Ravenel’s recent allegations against her — and the Southern Charm star is firing back with some of her own.

In new court documents obtained by The Blast, Dennis is requesting that Ravenel — with whom she shares daughter Kensington Calhoun, 4, and son St. Julien Rembert, 3 — produce a series of documents that are in his possession and relate to their ongoing custody battle.

Dennis, 26, is requesting that Ravenel, 56, “identity every prescription drug and/or illegal drug that you have used during the past 6 years. For each prescription drug, please identify the doctor who prescribed the drug where you purchased your prescription drugs,” according to the documents.

The mother of two also inquires about a supposed party that Ravenel allegedly hosted and where illegal drugs were present.

“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?” the documents state.

PEOPLE has reached out for comment from Ravenel’s and Dennis’ attorneys.

Dennis lost custody of the children and entered rehab in 2016 after she failed a drug test, testing positive for marijuana. (Years earlier, Ravenel went to a 30-day rehab program himself; he served 10 months in federal prison after being indicted by a federal grand jury in June 2007 on a charge of conspiracy to possess with intent to distribute less than 500 grams of cocaine.)

In 2016, Ravenel was awarded full custody, but Dennis has since earned back 50/50 custody. In October, she filed documents in Charleston seeking to obtain primary custody of the two children, and on Nov. 6, Ravenel filed a counterclaim, vehemently denying all of Dennis’ allegations.

In his recent filing, Ravenel claimed that Dennis “buys, sells, and trades prescription medications to and from friends, cast members, and show producers to support her prescription drug habit.”

Now, she is requesting that Ravenel produce “any and all evidence (whether photos, statements, videos, documents, etc.)” that he has that supports his allegations that Dennis ” ‘abuses prescription drugs’; ‘is engaged in the use of illegal drugs’; ‘buys, sells, and trades prescription medications to and from friends, cast members and show producers’; and/or ‘has been intoxicated by the abuse of prescription drugs and/or use of illegal drugs while in the sole care and control of the parties’ minor children.’ ”

Among his series of previous claims, Ravenel alleged that Saint’s “developmental and behavioral problems” are a result of Dennis’ alleged “drug and alcohol consumption” while their son “was in utero.”

A source previously told PEOPLE that Saint has “tubes in his ears” and his speech was delayed as a result. “His eustachian tubes weren’t draining, so he had his adenoids out and needed tubes in his ears — like lots of little kids his age who have that same problem,” the source said.

She is now requesting “any evaluations of your son that have been performed by a medical doctor as to his abilities (whether for processing, speech, OT, or otherwise).”

In the new court documents, Dennis also asked about Ravenel’s own well-being — specifically his mental health.

“Have you ever been evaluated for a potential diagnosis of bipolar disorder or any other mental health issue, diagnosis or illness?” the documents state and ask him to provide the date of the evaluation and the name of the medical individual “who performed the evaluation.”

Dennis asked that Ravenel provide “copies of all your medical, psychological, counseling or other related records” from Jan. 1, 2008 to the present; “a comprehensive print-out of all prescription drug purchases made by you” from Jan. 1, 2014 to present; “all medical and/or counseling records that you have obtained that relate to” Dennis; “all rehabilitation records that you have obtained related to” Dennis; and “all drug/alcohol test results/reports that you have in your possession that you have had Kathryn Dennis take and/or which you have taken.”

Among her claims, Dennis alleged in the new court documents that Ravenel hired a private detective.

She has requested “copies of any private detective reports, notes, emails, correspondence, videos, pictures, GPS logs, billing statements (showing the time & date of surveillance and billing rate), and/or any related documents obtained by your private detective which have been retained by you or your counsel.”

Ravenel, who was arrested and charged with assault and battery in the second degree in September following allegations of sexual assault brought against him by his children’s former nanny, has also been asked to provide past correspondences he’s had with any of his alleged accusers and that he “identify each and every woman who has accused you of either assaulting her and/or sexually assaulting her,” the documents state.

The documents state that she wants her ex to “produce all text messages, email messages and/or other communications that you have sent to or received” from a number of women, whom she identified in the documents, “since January 1, 2016.”

She later requests in the documents “a copy of your complete file and any related documents regarding the sexual assault allegations made by” the former nanny Dawn. PEOPLE do not identify alleged victims of sexual assault, however, Dawn has previously chosen to identify herself publicly. Dennis also wants “a complete copy of all communications between” Ravenel and “any other women who have made allegations of inappropriate conduct by you” as well as copies of “any and all settlement agreements that you reached and payments that you have made (by yourself or through your attorneys).”

Among her series of requests, Dennis also asked for Ravenel’s “credit card monthly statements” from Jan. 1, 2016 to the present; “itemized cellular/mobile phone records” from Jan. 1, 2016 to the present; and copies of electronic or social media posts from the past four years, as well as whether Ravenel has “had any discussions” with on-off girlfriend Ashley Jacobs “about marriage and/or plans to marry Ashley Jacobs.”
