The law firm Buckley sued actor Johnny Depp on Monday, claiming the star actor failed to pay $348,000 he owes the firm for its work litigating a legal malpractice suit against his previous lawyers.

Buckley said in a complaint filed in Los Angeles Superior Court that it spent a year and a half trying to claw back some $30 million from Depp’s former lawyers at Bloom Hergott Diemer Rosenthal LaViolette Feldman Schenkman & Goodman. Depp has accused Bloom Hergott of illegally taking contingency fees without a written agreement.
