Ravenel was granted custody of the children two years ago with an agreement to work with Kathryn towards fifty/fifty parenting.

The arrangement appeared to be working until Kathryn filed for sole custody last October in the wake of allegations of sexual assault made by the couple's former nanny, Dawn Ledwell.

Those allegations resulted in criminal charges for which Ravenel is currently awaiting trial.

Now Ravenel is fighting back with explosive new legal filings that are tantamount to a complete character assassination.

The filings seek to show Kathryn as a negligent mother, mentally unstable, heavily medicated, sexually active with multiple men and hopelessly reckless with her finances.

To add salt to the wounds these documents appear designed to inflict on his ex, Ravenel claims that he had believed that Kathryn had 'truly rehabilitated herself,' and was 'ready to share fifty-fifty time…and help financially support her life with Kensie and Saint.'

Now, he states, he views the prospect of her gaining even joint custody as, 'terrifying.'

But, had she not filed this custody action, Ravenel states,'I would never have known how at risk Kensie and Saint are in Kathryn's care.'

Self-medication: Drink and Drugs

Kathryn's history of drug abuse is well documented but, according to Ravenel and his team, it is not - as she would have people believe - a thing of the past.

Last month she failed a mandatory blood test that is part of their current custody agreement, testing positive for marijuana, benzos and amphetamine.

The 27-year-old mother of two is accused of having bad spending habits, which her ex calls 'excessive and out of control'

Ravenel's expert witness, forensic psychiatrist Dr Timothy Brewerton lists a staggering 17 diagnoses ascribed to Kathryn's mental health issues including bi-polar, ADHD and PTSD. He goes on to list 17 medications she has been recently and/or is currently being prescribed.

He concludes that she is continuing to take both 'uppers' and 'downers' and states, 'Multiple medications for similar complaints indicate either that the patient is not taking the medication as prescribed or not suffering from the complaint they are prescribed for.

'She always returns to Klonopin and Adderall, two drugs that can be characterized as ''high risk for drug abuse.'''

He also notes that she told staff at Promises rehab, which she attended in July 2016, 'I am a slave to marijuana.'

Ex-boyfriend Ashley Pillar dated Kathryn after that stint in rehab from the Fall of 2016 to the summer of 2017.

He has given an affidavit in which he states that during their time together, 'she was addicted to prescription medications, marijuana, alcohol, and sex.'

He took pictures of the 'inordinate amount' of prescription medication bottles she carried with her.

According to Pillar, 'I saw Kathryn self-medicate on uppers and downers depending on her mood every day…Kathryn was regularly on a cocktail of the two.'

In undated text message Lara Dawson, a friend of Kathryn's, appears to try to buy Adderall illicitly on Kathryn's behalf.

He claimed she 'always' took Adderall then would have to take a downer to help her sleep.

Pillar is also prescribed Adderall and said, 'It got so bad I started hiding my medication from her.'

In undated text message Lara Dawson, a friend of Kathryn's, appears to try to buy Adderall illicitly on Kathryn's behalf. It reads: 'I have Kathryn here at my house in a f***in full panic attack mode - she has been on Adderall since 14 and her ex stole her entire bottle….I told her I would do everything I possibly could to get her covered and she will come to you and pay you well.'

Elsewhere, a prescription for Adderall in addition to her regular amount includes the prescribing doctor's notes, 'Reports meds were stolen when she was in New York. She's been out of meds for 3d. Only Adderall was taken.'

Pillar also claims that Kathryn 'routinely mixed her prescription medications' with dark liqor - Bourbon or Whiskey (straight).

He claims that there were many occasions on which he had to 'look after Kathryn due to her drinking, partying, or sleeping late on pills.'

According to Pillar her Southern Charm pay was cut because she 'consistently' failed to show up for filming on time as a result.'

Rehab or Ruse?

Medical records show that during her time at Promises Rehab Kathryn was briefly hospitalized and had an abortion.

In his affidavit Ravenel states, 'This makes me wonder if Kathryn's time at Promises was a ruse and that she really went to California to have an abortion.'

The records also show that she did not participate in any of the group sessions she was assigned to.

Ravenel states, 'Kathryn's credit car and bank records show that immediately upon her return from rehab in July 2016, Kathryn began drinking again.'

Certainly the statements show she began spending significant sums of money in liquor stores and bars. Between August and October 2016 the total expenditure was $1,239.63.

Credit card statements also show repeated purchases of a product called Test Clear, which provides synthetic urine and detoxifying shampoo to help pass drug tests.

Men

Kathryn is now publicly dating country singer Hunter Price. In a text from Ravenel to Kathryn dated March 2019 Ravenel takes issue with the fact that Price has been staying overnight when she has the children in the house.

This is in breach of their custody agreement that states that no 'paramours' will stay overnight unless they are married.

In his affidavit Ravenel claims, 'I wouldn't have such a problem with Hunter living with Kathryn if I felt that Kathryn was capable of being in a healthy, long-term relationship.

But according to Ravenel the opposite is true and her 'hyper sexuality' was an issue in his own relationship with her.

He claims that when she was pregnant with Saint 'she hooked up with one of my polo players on a weekend we spent together with Kensie in Aiken.'

She was, he continues, 11 weeks 3 days pregnant and went out 'drinking..and slept with Pedro.'

Ex Pillar states that while they were dating, 'sexually explicit text messages from a guy popped up on her phone,' and that he found out that she was sending 'sexually erotic photos and text messages' to 'multiple men,' while they were dating.

They broke up soon after.

Some explicit text messages to an unnamed man, who is clearly in a relationship, are included as exhibits. In them, Kathryn talks of taking Adderall and drinking red bull in order to stay up for sex. They are not dated nor is there any indication that Kathryn was looking after the children at the time they were sent.

Money

According to Ravenel the chaos of Kathryn's existence is reflected in her spending which, he presents, as excessive and out of control.

He claims that she owes 'hundreds of thousands of dollars in back taxes' and has not filed since 2015 despite making a six-figure salary during those years.

Kathryn has disputed this saying she has retained an accountant and is in the process of filing.

He claims that she spent $85,000 on hair, make-up and clothing in 2018 and $90,000 in 2017. From June 2017 to October 2018 she spent $34,000 on traveling.

He points out that she rented a house in downtown Charleston for $6,600 and recently had to move out, as she could not afford it. And that she 'attempted to purchase a Rolls Royce for $125,000.'

This, and everything else that he has learned during discovery, Ravenel states, 'gives me serious concern for her ability to meet basic needs and provide our children with a stable environment.'
