Ryan Phillippe has filed a legal response to soon-to-be ex-wife Reese Witherspoon
's divorce claim, according to court documents obtained by PEOPLE.
In his filing submitted Tuesday, Phillippe, 32, cites irreconcilable differences as the reason for their split, and also seeks joint custody over their two kids, daughter Ava, 7, and son Deacon, 3.
The documents ask that child visitation be "equally allocated."
