The 41-year-old actor and 38-year-old actress’ divorce announcement comes a little over a year after they revealed their separation.
The couple share two children – 13-year-old Indiana and 9-year-old Atticus.
Summer cited irreconcilable differences as the reason for their split and is requesting spousal support and joint physical and legal custody of their children.
The two met back in 1995 after Summer‘s brother Joaquin worked with Casey‘s brother Ben on To Die For.
The couple dated for many years before marrying in 2006.
