Per the lawsuit, Kardashian claims Dream Kardashian's momma consumed drugs and alcohol on December 14, which resulted in violent and erratic behavior.
Chyna and her legal team accused Rob of violating California's revenge porn laws, claiming in court documents obtained by PEOPLE that he allegedly hit her and threatened to kill himself multiple times.
The siblings also say BC committed "nothing short of an outright fraud to shake down the Kardashian family without any concern about the consequences" by entering into a relationship and having a baby with Rob.
As for Rob and Chyna's reality show, the docs say E! tried to make a second season work, but realized filming the show would not be safe for the network. In the papers, Rob details an incident that went down on December 14, where he claims Chyna "became extremely intoxicated on drugs and alcohol and physically assaulted" him while carelessly playing with his gun.
The suit describes Chyna as a stripper who created a reputation as a money-hungry pseudo-celebrity.
Rob has mainly kept out of the spotlight since he posted a lengthy rant and a string of intimate pictures of his former fiancé and the mother of his 11-month-old daughter Dream Renée, Blac Chyna, online.
Rob says he attempted to get in his Bentley and drive away, but "Chyna threw a nearby chair at Rob's auto causing damage to the vehicle and also used a metal rod to injure Rob".
