A woman who accused Mayor Eric Adams of sexually assaulting her in 1993 told nine people about the encounter and documented her account in emails years ago, her lawyer said in a legal filing on Monday.

The filing did not contain specific details about what she said to each person or when she said it. But it did say that she told seven of the nine people he had assaulted her before the Adult Survivors Act took effect in 2022. That legislation opened a window for people to bring lawsuits over sexual assaults said to have occurred years ago.

The woman provided two documents showing that she sent emails about the assault in 2021 when Mr. Adams was running for mayor and before she had the ability to sue him under the new state law, according to the filing, which was a letter written to the judge, Richard G. Latin, of the State Supreme Court.

Mr. Adams has denied the allegations, and his allies have sought to attack the woman’s credibility and her history of filing lawsuits. Her past comments to people about the assault and any written documentation of it could be central to the lawsuit.

The mayor’s legal team has been battling with the woman’s lawyer, Megan Goddard, in court documents ahead of her deposition, which could take place as early as this summer.

The woman said she worked with Mr. Adams at New York City’s transit police bureau. After she asked him for help with a promotion, Mr. Adams drove her to a vacant lot and requested oral sex, according to the 26-page complaint. When she declined, he forced her to touch his penis and ejaculated on her leg, the complaint said.
