It doesn’t look as if Jay Mohr will be calling off his divorce from Nikki Cox a second time.

In new court documents, the comedian, 46, alleges that his estranged wife, 38, is battling drug and mental health problems, according to People magazine. He is also asking for sole physical custody of the couple’s son.

In the papers, Mohr claims that he and Cox have continued to live in the same residence since he filed for divorce, for a second time, last December, and that it has had a negative effect on the couple’s 5-year-old son, Meredith Daniel.

He highlighted several instances he claims illustrate Cox’s inability to care for the couple’s son, including leaving the oven on while she and Meredith were asleep and administering a double dose of medicine that caused the boy to vomit in the middle of the night. The actor also said her presence has caused Meredith to regress emotionally and that the child “has been urinating and defecating in his pants.”

“Nikki’s poor parenting decisions affect Meredith’s well-being,” read the papers, which were obtained by People. “Her refusal to discipline Meredith has made me the parent who enforces the rules in our house. When I have checked on Meredith in the middle of the night, I have walked into the master bedroom to see Meredith and Nikki awake at 2:00 a.m, watching cartoons and eating candy.”

Mohr also said that Cox came to him this January and told him she thought she was pregnant again and that the child was his, even though he is azoospermic, meaning that his semen contains no sperm.

Last July, Mohr filed for divorce from Cox claiming that the actress self-medicated to cope with depression and that he feared for their son’s safety.

He rescinded the petition six days later, telling Page Six, “We are very married, very in love and that’s really all there is.”

In the documents, Mohr also explained why he filed for divorce a second time, stating, “While I acknowledge that I still love Nikki, I also acknowledge that we can no longer be married to each other, and I cannot continue to raise our son in a toxic environment.”

The comedian and Cox started dating in 2004 and married two years later. He has another son, Jackson, from a previous marriage to model Nicole Chamberlain.

Representatives for Mohr declined a request for comment.
