The two wed in 2006 and separated in 2016. She filed for divorce this summer. They had a prenuptial agreement.
In November a judge signed off the papers for the divorce, according to People. The actor was ordered to pay his ex spousal and child support.
The documents show that Summer cited ‘irreconcilable differences’ as the reason for the split. She asked for joint legal and physical custody of their children as did he.
The pair tied the knot back in 2006, having met in 1995 through Summer’s brother Joaquin Phoenix, who was working with Casey on To Die For.
