McDermott, 46, who previously announced their separation, seeks joint custody of their daughters, Collette, 12, and Charlotte, 2, according to the Los Angeles Superior Court papers filed Friday.
The papers cite the usual irreconcilable differences as the reason for the split.
McDermott, best known from TV's The Practice, and Rose, 39, an actress, were married in 1995 and separated in March 2007, according to the papers. McDermott, who played an attorney on TV, is acting as his own lawyer in the divorce, according to the papers.
