The divorce papers come roughly one month after police were called to the Wainstein home.

E! News learned at the time that the Real Housewives of New York star called the police on her estranged husband after feeling threatened by her ex. "Jules was the one who called the police," a source told us, adding that Jules needed help because Michael was speaking to her in a threatening manner. No arrests were made.

The call to police came shortly after the reality star announced that their marriage has come to an end after eight years together. The insider added, "This divorce is contentious and it's going to be ongoing."

Michael filed for divorce from Jules after she allegedly caught him cheating on her. "They were having issues before the show but I think pressure from filming clearly put a strain the marriage," an insider previously told us before adding, "It brought things to a head."

The Bravolebrity was also hit with a lien for allegedly refusing to pay $25,000 in bills related to her lux New York condo, which E! News has learned is not the family home, but Jules' apartment that she lived in prior to her marriage.

According to The Daily Mail, The Board of Managers of the Apthorp Condominium filed a lien against Wainstein accusing her of not paying them $25,243.74 in costs related to commons charges and other amounts potentially linked to association fees.

E! News has reached out to both parties for comment.
