The new court documents, which were filed on Monday and obtained by The New York Times on Tuesday, contain a series of details that describe what Ms. Miniutti alleges took place during the night in question. In the documents, Ms. Miniutti, an actress, refers to Mr. Avenatti, 47, as her “boyfriend.”

In a sworn declaration, Ms. Miniutti said she and Mr. Avenatti dated from October 2017 until Nov. 13, the night she alleges that they began to argue about money and that Mr. Avenatti berated her using expletives.

After the alleged verbal abuse, Ms. Miniutti said, she went to a guest bedroom in the apartment she says they shared to sleep alone. But Mr. Avenatti followed her, according to the declaration, and eventually began “forcefully” hitting her in the face with pillows.

Ms. Miniutti alleges that Mr. Avenatti then “grabbed my right arm and dragged me out of the bed.”

“He dragged me on the floor of the apartment towards and out of the door into the public hallway,” she wrote in the declaration. “I was wearing only my underwear and a T-shirt at the time, and suffered scratches to the bare skin on my side and leg.”

Mr. Avenatti then pulled Ms. Miniutti back into the apartment and initially blocked the door, the declaration says. Ms. Miniutti said she was eventually able to get around Mr. Avenatti and leave the apartment, but he followed her into an elevator, where she says he “repeatedly begged, ‘Don’t do this Mareli, don’t involve them.’”
