The statements were detailed in court papers filed by the Manhattan district attorney’s office: a notification known as a voluntary disclosure form, which prosecutors are required to provide to defense lawyers within 15 days of a defendant’s arraignment.

The papers were dated Tuesday, but it was unclear when they were provided to Mr. Strauss-Kahn’s lawyers, William W. Taylor III and Benjamin Brafman. Mr. Taylor declined to comment on the contents of the documents.
