A federal judge ruled on Friday that Cohen's legal team must publicly file any challenge they make against a special master's decision on evidence seized from Cohen during the raid.
Michael Cohen, who was President Donald Trump's longtime personal lawyer, is likely preparing to cooperate with federal prosecutors once he is dropped by the law firm that has been representing him, ABC News reports.
Lawyers for Mr. Cohen didn't respond to requests for comment.
Following a 9 April raid on his residences and office, Cohen has been represented by Stephen Ryan and Todd Harrison of the firm McDermott, Will & Emery LLP. Stormy Daniels, the adult film star who claims she had sex with Trump in 2006 and was then paid $130,000 to keep quiet about it, has also asked to join the case.
The AP reports federal prosecutors in NY have publicly said they are investigating alleged fraud in Cohen's business dealings, but haven't disclosed details.
CBS News correspondent Jeff Pegues, who has been in contact with Cohen, reports there appear to be changes afoot in his legal strategy going forward - on the key question of whether Cohen is ready to cooperate, or whether he will decide to do battle in court.
The source said Cohen had not yet met with prosecutors to speak about a potential deal, and it's unclear whether either side is seeking one.
Trump has acknowledged that he reimbursed Cohen for the payment, but he has denied that the affair with Daniels took place.
