Sean “Diddy” Combs is facing a dispute with his civil attorneys, who have asked a court for permission to withdraw from representing him over unpaid legal fees.

Attorneys with the New York law firm Sher Tremonte claim Combs is significantly behind on payments and has become difficult to work with.

Combs disputes that account, saying he decided to change attorneys because of disagreements over charges he says were not approved. His former attorneys deny overcharging him.

The firm represented Combs in several civil cases, including a defamation lawsuit he filed against Nexstar Media and others.
