Jenji Kohan has filed for divorce from after two decades together.
Kohan and Noxon, who were married for 21 years, share three children together: daughter Eliza and sons Charlie and Oscar.
A rep for Kohan did not immediately respond to PEOPLE’s request for comment.
Noxon, who is best known for his 2006 book Rejuvenile: Kickball, Cartoons, Cupcakes, and the Reinvention of the American Grown-up, is asking for spousal support while Kohan is asking to deny him support, as reported by TMZ.
News of Kohan’s divorce filing comes over a year after she signed a lucrative multi-year deal with Netflix.
Kohan, who also created Weeds and GLOW, was a key part of the streaming service’s launch of original programming in 2013.
OITNB announced in October that the series will end after season 7.
“After seven seasons, it’s time to be released from prison,” Kohan said in a statement. “I will miss all the badass ladies of Litchfield and the incredible crew we’ve worked with. My heart is orange but fade to black.”
Season 7 of Orange Is the New Black will premiere in 2019 on Netflix.
