Jay Z's one-time business partner claims Roy, who he divorced in 2009, needs to pay up amid accusations of breach of contract and interference with cash distributions due to him from their firms Royale Etenia LLC and Topson Downs, reports TMZ.com.

He filed suit in a U.S. court on Thursday (23Apr15), just three days after a judge awarded Roy full custody of their daughters, 15-year-old Ava and six-year-old Tallulah. Dash was granted supervised visitation.
