Actor Ashton Kutcher has filed to officially end his marriage to Demi Moore, more than a year after their split.

The Hollywood couple announced its separation in November, 2011 after six years as husband and wife, and now the Two and a Half Men star has kickstarted the divorce process.

Kutcher, who has hired celebrity attorney Laura Wasser to represent his case, filed papers in Los Angeles Superior Court on Friday, citing irreconcilable differences for the break-up.

He is not seeking spousal support and has not asked a judge to deny Moore financial aid should she request it, according to People.com.

The couple, which wed in 2005, does not have any children.

Kutcher, 34, has since moved on to romance his former That �70s Show co-star Mila Kunis, while 50-year-old Moore was most recently linked to director Julian Schnabel�s art collector son Vito.
