Courteney Cox and David Arquette
06/14/2012 at 09:15 AM EDT
and David Arquette's divorce appears to be as amicable as can be.
The actress filed divorce papers on the same day as Arquette's June 8 filing
in Los Angeles Superior Court. Cox's filing, which surfaced the day after her ex's papers, cites the same reason for the split and requests the same custody arrangement.
Like Arquette, Cox, 47, cites irreconcilable differences and seeks joint legal and physical custody of their 8-year-old daughter Coco.
Cox, who also requests to drop "Arquette" from her last name, is representing herself without lawyer, just like her former significant other.
Cox told PEOPLE
in January that she and her ex have remained "best friends" even since announcing their separation in 2010
